Charaxinae (Lepidoptera: Nymphalidae) has a worldwide distribution, although it occurs mainly between the tropics. Most species occur in the Neotropics, where three tribes, Preponini, Anaeomorphini, and Anaenini, can be found. Collectively, these three tribes encompass 109 species. Because of its relevance to systematics and taxonomy, the male genitalia of Lepidoptera have been extensively studied. The male genitalia are composed of the last two abdominal segments and their modifications for mating, known as claspers of the bodies. In order to improve upon the systematic classification of the subfamily, 31 species of 13 genera of Neotropical Charaxinae were analyzed. All characters relevant to species and generic taxonomy were analyzed. Most structures showed morphological variations among tribes, genera, and species. These variations demonstrated to be important to Preponini, because the structural patterns of the genitalia allow the separation in two groups, Prepona Boisduval and Archaeoprepona Fruhstorfer, and are in accord with the recent taxonomic classification proposed by Ortiz-Acevado and Willmott (2013), wherein Agrias Doubleday is synonymized in Prepona and Noreppa Rydon within Archaeoprepona. In the same way, Anaeomorpha splendida Rothschild showed considerable differences from Preponini's genera, the tribe in which it was included, confirming the revalidation of the tribe Anaeomorphini (Ortiz-Acevado and Willmott 2013). Substantial variation was found in the genital structures of Anaeini, making it difficult to establish structural patterns for this group. Such structural variation, however, may be very efficient to diagnose species, such as some species of Memphis Hübner and Fountainea Rydon, which can be easily identified through the presence and location of spines on the valva.
Introduction
The male genitalia of butterflies has been the subject of several very detailed studies, as its morphology can provide the basis for work of taxonomy, systematic analysis, and phylogenetic analysis (Simonsen 2006a). Some recent work on the comparative morphology of male genitalia has examined genital muscles (Simonsen 2006a, b) and intraspecific structural variations (Caldas 1997; Tóth 2011).
Charaxinae (Lepidoptera: Nymphalidae) are a group of medium to large, robust butterflies. They fly fast and circulate around tree canopies, behaviors that make them difficult to observe. Males and females are easily attracted by bait containing fruit, decomposing animals, feces, urine, and/or sweat (Rydon 1971). Charaxinae butterflies occur mainly between the tropics, primarily inhabiting the Neotropical region (Mielke et al. 2004a).
Recently, this subfamily has undergone drastic changes in its taxonomic classification. Through phylogenetic study of the tribe Preponini, using data from DNA sequences, Ortiz-Acevado and Willmott (2013) classified Preponini as follows: two genera were synonymized, Noreppa to Archaeoprepona and Agrias to Prepona; the fifth genus (monotypic), Anaeomorpha splendida, had its tribe status revalidated to Anaeomorphini. So, the neotropical Charaxinae contained two tribes, 17 genera, and 109 species (Salazar and Constantine, 2001; Lamas, 2004; Salazar, 2008), and today is made up of three tribes, 15 genera, and 109 species (Ortiz-Acevado and Willmott 2013).
The Charaxinae are characterized by the following synapomorphies: parapatagium sclerotized (Ehrlich 1958); forewings with R4 and R5 longer than their common branch; R4 curved downward near its end, which may be at the costal margin, the apex, or the outer margin of the wing; posterior discal cell closed; anepisternum II present as a distinct sclerite; and mesothoracic pre-episternum well-developed (Ackery 1984). These synapomorphies were corroborated in a series of contributions by Mielke et al. (2004a, b, c), who also found some variation in the way vein R4 ends in Zaretis itys itylus (Westwood) and Prepona claudina annetta (Gray).
With the goal to clarify the classification and systematics of the Neotropical Charaxinae, we have illustrated, compared, and ascertained variation in the male genitalia of 31 species of 13 genera. Some of the characters mentioned have been previously mentioned in other literature, whereas others are new.
Materials and Methods
The species studied and material studied are listed in Table 1. The specimens analyzed are retained at Coleção Entomológica Pe. Jesus Santiago Moure, Departamento de Zoologia, Universidade Federal do Paraná, and Coleção Prof. Dr. Olaf Mielke.
The abdomen of each exemplar was removed and immersed in potassium hydroxide 10% for at least 24 hours (depending on the size of the abdomen) to soften the tissues. After that, the abdomen was washed in water.
The genitalia were removed through a slit on the pleura of the 7th abdominal segment. After study, the genital parts were stored in a microvial containing glycerin, which was attached to the same pin as the exemplar.
Drawings were made using a camera lucida attached to a dissecting microscope. The main lines were inked and watercolor was used to mark each sclerite with a different color.
Illustrations were coded as follows: full lines represent the boundaries of morphological structures on the first focal plane; dashed lines represent the boundaries of structures that lay underneath the main structure under study. As with structures represented by dotted lines, structures represented by dashed lines were only shown when they were important for the interpretation of the genital anatomy. Sclerites lacking a well-defined boundary were represented by intermediate colors. Sclerites, and their respective color codes, are as follows: tegumen - yellow; saccus - cadmium red; uncus - navy blue; gnathos - alizarin red; fultura inferior - turquoise; valvae - lemon yellow; penis - green.
In some illustrations, the sclerites were omitted in order to facilitate interpretation. For instance, the fultura inferior was omitted from illustrations showing the lateral aspect of the genitalia. A minimum of nine drawings were produced for each species as follows: lateral, dorsal, and posterior aspects of the genitalia; inner and outer aspects of the valva; and lateral (left and right), dorsal, and ventral aspects of the penis. In the descriptions and comparisons, only the greatest values are given for width and length.
SEM photographs were taken following standard procedures. First, the parts were dehydrated by immersion in decreasing ethanol dilutions (70%, 80%, 90%, and 100%) for 10 minutes, and then immersed for an additional 10 minutes in ethanol absolute. Second, they were subjected to critical point drying, glued to a stub, and coated.
The main terminology used was adopted from Niculescu (1978) (Figure 1), with adaptations from Petersen (1904), Pierce (1909; 1914), Kuznetsov (1915), Snodgrass (1935), Oiticica (1946), Okagaki et al. (1954), Sibatani et al. (1954), Klots (1956), Ogata et al. (1957), Snodgrass (1957), Srivastava (1965), Casagrande (1979), and Bilotta (1994).

Discussion
Tegumen
This sclerite is structurally diverse across the group, with differences in at least five areas. Four shapes have been identified in lateral view: (1) semi-trapezoidal, clustering species of Agrias, Prepona, and Hypna, as well as Memphis philumena corita, Memphis lemnos, and Memphis polyxo; (2) rectangular, common to species of Archaeoprepona and Noreppa; (3) triangular, clustering Anaea troglodyta with Anaeomorpha splendida; and (4) subtriangular, common among species of Anaeini, and clustering species of Coenophlebia, Consul, Fountainea, Prozikania, Pseudocharaxes, Siderone, Zaretis, and most species of Memphis.
With a few exceptions, enumerated below, the anterior projection of the tegumen is developed. It is lacking in most species of Fountainea (the anterior projection is found only in Fountainea ryphea phidile, of the four species studied) and a few species of Anaeini (Memphis acidalia victoria, Memphis lemnos, and Prozikania suprema). When present, the anterior projection of the tegumen is often developed, longer than wide or as wide as long. Such projection is reduced or is as wide as long only in Anaeomorpha splendida, Archaeoprepona amphimachus pseudomeander, and Archaeoprepna demophon muson.
Other modifications in the tegumen were the presence or absence of a fold in the tegument on the anterior margin and appendices angulares. The latter are ubiquitous among the species studied and vary in their dimensions, being wider than long, as wide as long, or longer than wide.
Saccus
Some differentiation between the ventral arms from the tegumen and the dorsal arms from the saccus was found in 23 of the 31 species analyzed, with special emphasis for P. xenocrates punctimarginale, with the arms of the tegumen separated and distant from the arms of the saccus. Therefore, the fusion between these two structures has not revealed a suitable character to group species or genera.
Thirty species have a saccus with an anterior projection. The degree of development of this projection varies among species, and six shapes have been identified for it: oval, common among species of Agrias and Prepona; rectangular, a shape found only in Anaea troglodyta; subtriangular, characteristic of Anaeomorpha splendida, Archaeoprepona demophoon andicola, Archaeoprepona licomedes licomedes, Pseudocharaxes xenocrates punctimarginale, and Memphis lemnos; subrectangular, as in Archaeoprepona amphimachus pseudomeander, Archaeoprepona domophon muson, and Memphis hirta; triangular, as in Archaeoprepona meander castorina and Memphis glauce glauce; and elongated, characteristic of species of Consul, Fountainea and Hypna, as well as Coenophlebia archidona, Noreppa chromus chromus, Prozikania suprema, Siderone nemesis catarina, Zaretis isidora, Memphis acidalia victoria, Memphis moruus stheno, Memphis phlilumena corita, and Memphis polyxo.
A posterior projection arising from the saccus was present in approximately 50% of the species studied. This projection can be shorter than the anterior projection, a widespread state, or it can be subequal to or longer than the anterior projection, a state present in Anaeomorpha splendida and Archaeoprepona domophon muson.
Uncus
Among the structural differences found in the uncus, we highlight its shape in lateral view, which can be thick (three times longer than wide) or slender (more than three times longer than wide). The tribe Preponini contains only one species with a slender uncus, Archaeoprepona meander meander. All other species in this tribe, as well as the species Hypna and Coenophlebia (Anaeini), have a thick uncus. The uncus is slender in species of Anaea, Consul, Memphis, Fountainea, Siderone, Prozikania, Pseudocharaxes, and Zaretis.
The uncus also varies in the presence or absence of setae on its dorsal portion. The uncus of Anaeomorpha splendida, Archaeoprepona amphimachus pseudomeander, and Prepona laertes laertes have a dorsal seta. Other differences in this structure among species are as follows: the presence or absence of crests (present only in two subspecies of Hypna clytemnestra), presence or absence of spines on the dorsal portion (present in Anaeomorpha splendida, Archaeoprepona amphimachus pseudomeander, and Prepona laertes laerte), and the presence or absence of a fenestra. When present, the fenestra may be found either on the central portion (Pseudocharaxes xenocrates punctimarginale and Siderone nemesis catarina) or at the base of the uncus (Hypna clytemnestra forbesi and Hypna clytemnestra huebneri).
Anal tube
The degree of sclerotization of the ventral portion was the only difference found in the anal tube. Species that have the ventral portion of the anal tube sclerotized were considered as having a subscaphium. This character can be used to separate between Anaeini, Anaeomorphini and Preponini. Species of Preponini and Anaeomorphini do not have a subscaphium, whereas species of Anaeini do, with two exceptions, Fountainea nessus and Fountainea ryphea phidile.
Gnathos
The gnathos has two basic shapes in the species studied. It may form a handle enveloping the anal tube, in which case it is called “single” or “close,” or it may be divided into two distinct arms, and be called “double” or “open.” In our sample, the gnathos is single in species of Anaeini and double in species of and Anaeomorphini Preponini, with some modifications among species.
Five aspects were identified concerning the shape of the gnathos: elongated, present in species of Agrias and Prepona; shaped as an anvil, unique to Anaea troglodyta; covered by the tegument, unique to Anaeomorpha splendida; thick, present in Archaeoprepona and Noreppa; with base wider than distal portion, as in Anaeini, except for Anaea troglodyta. Regarding the modifications on the distal portion, they can be smooth, with spiny club, or with distal margin serrated or striated and enveloped by membranes.
Valvae
The valvae assume various shapes: triangular, as in Agrias and Prepona; subtriangular, in species of Anaea, Anaeomorpha, and Archaeoprepona; circular, common to the species of Hypna and Consul, as well as Memphis acidalia victoria, Memphis hirta, and Memhis polyxo; rectangular, as in Pseudocharaxes xenocrates punctimarginale, Siderone nemesis catarina, and Zaretis isidora; and subrectangular, as in all species of Fountainea, Coenophlebia archidona, Memphis philumena corita, Memphis moruus stheno, Memphis lemnos, Memphis glauce glauce, and Prozikania suprema.
Besides the shape, the structure of the valvae may also vary. For instance, the presence of an apical projection is a variable feature within tribes, but stable within genera. In our sample, the valva of all species of Archaeoprepona, Fountainea, Consul, Prozikania, Pseudocharaxes, and Memphis (except for Memphis moruus stheno) had an apical projection.
Beyond the characters described above, the following features have been found to be variable: presence or absence of spines on costa (present in Fountainea halice halice, Memphis glauce glauce, Memphis hirta, Memphis polyxo); presence or absence of spines on the saccus (present in species of Memphis); presence or absence of an apical projection of the valva, presence or absence of setae on the inner tegument of the valva (present only in Memphis lemnos and Pseudocharaxes xenocrates punctimarginale). These characters can be further investigated, and the location and shape of spines can be detailed.
Fultura inferior
Differences were found in the fultura inferior of all species. Within this structural diversity, we were able to devise some basic aspects. One is the general shape, with six variations: rectangular, as in all species of Agrias and Prepona; semi-circular, as in Anaeomorpha splendida, Fountainea ryphea phidile, Prozikania suprema, and Pseudocharaxes xenocrates punctimarginale; elongated, present only in Coenophlebia archidona; V-shaped, present among Hypna subspecies; narrow, stripe-like, unique to Memphis hirta; and bilobed, present in all other species analyzed.
Other characters identified for the fultura inferior were useful for grouping species, such as the presence of absence of tegument folds, uniting species of Agrias and Prepona. Another such character is the presence or absence of spines and their location.
Penis
The penis presents variations in the aedeagus, which can be completely sclerotized or membranous ventrally. A ventrally membranous aedeagus was found in the studied species of Archaeoprepona and Noreppa.
Another character that varied in the penis was the direction of the projection from the bulbus ejaculatorius. It was ventral in species of Agrias and Prepona, and also in Noreppa chromus chromus. In Archaeoprepona licomedes licomedes and Archaeoprepona meander castorina, this projection was ventral. It was dorsal in 25 of the 31 species studied.
Final considerations
The present analysis revealed the importance of conducting detailed morphological analyses that focus on certain tagmas, particularly for groups whose morphology has been neglected, such as the Charaxinae. It is possible that this group has been poorly studied because specimens are rare and consequently they are considered precious. For this reason, their taxonomy has been based on venation and coloration of the wings only.
The observation of Rydon (1971) was confirmed, because the differences of the gnathos, club-like and striated-like, were able to differentiate Archaeoprepona and Prepona. According to the results, species of Preponini can be divided into two distinct groups, Prepona (including Prepona claudina annetta) and Archaeoprepona (including Archaeoprepona chromus chromus), thus confirming the arrangement of the genera proposed by Ortiz-Acevedo and Willmott (2013).
Among the characters observed in this study, the following putative synapomorphies support groups within Preponini:
Archaeoprepona: Aedeagus with ventral portion membranous and distal portion of gnathos striated;
Prepona: Presence of lateral folds in the tegument of the fultura inferior, and gnathos with a club covered with spines.
Morphological characters can resolve taxonomic problems, and can still be more exploited, thus making them more accurate when included in analyses such as female genitalia, color and shape of wings, and even the shape and color of odoriferous scales in males.
The structural modifications of Anaeomorpha splendida confirm a tribe, although in some aspects it resembles Anaea troglodyta, which deserves attention and further research about the degree of closeness between these two species belonging to different tribes, Anaeomorphini and Anaeini, respectively.
Contrasting with the genitalia of species of Preponini, the gentialia of Anaeini species is variable, making it difficult to establish structural patterns within this group. However, it is possible to distinguish among species based on some genitalic characters. For instance, species of Memphis and Fountainea are easily separated by the presence and location of spines on the valva. For Comstock (1961), the great variety of forms of gnathos, which despite having a structural pattern as a basal line can provide many features useful for the determination of species.
The results obtained herein reflect detailed dissections and observations of structures from different views (positions) that had not been previously used in the taxonomy of the group. Therefore, they include structures not previously considered. These characters can be used in the future in a phylogenetic analysis or when devising more consistent diagnostic characters for species and genera.
The detailing of such structures can be geared towards the maintenance of the status of Prozikania and Pseudocharaxes as genera, synonymized by Lamas (2004) with Polygrapha, the first as Zikania (nom. nud.), and again used by Salazar (2008). The significant differences in the genitalia of the species of both genera as described and illustrated in this study corroborate the observations of Comstock (1961), Rydon (1971), and Salazar (2008), justifying the maintenance of the genera, despite being monotypical.
