The genus MorphnodesHebard, 1930 is restored from synonymy with RhabdoblattaKirby, 1903. Detailed morphological descriptions of Morphna maculata (Brunner von Wattenwyl, 1865), the type species of the genus MorphnaShelford, 1910, of Morphnodes goliath (Shelford, 1906), Pseudocalolampra inexpectataRoth & Princis, 1971, and Colapteroblatta compsaHebard, 1919, the type species of the genus ColapteroblattaHebard, 1919, are given. The male genitalia of Morphna maculata and Morphnodes goliath and the ovipositor and adjacent structures of M. maculata and C. compsa are described for the first time. Relationships of the genera Morphna, Morphnodes and Rhabdoblatta are briefly discussed.
INTRODUCTION
This paper is devoted to cockroaches of the subfamily Epilamprinae (Blaberidae). It is the third paper of a series of papers dealing with this taxon. The aim of this and previously published papers (Anisyutkin, 2015, 2016) is to provide morphological descriptions which are detailed enough for further phylogenetic investigations.
Morphna maculata (Brunner von Wattenwyl, 1865) and Colapteroblatta compsa Hebard, 1919 are the type species of the genera Morphna Shelford, 1910 and Colapteroblatta Hebard, 1919, respectively. These are the type genera of the tribes Morphnini McKittrick, 1964 and Colapteroblattini Hebard, 1919, respectively. Consequently, the morphology of these species is important for the reconstruction of Epilamprinae phylogeny. The genera Morphnodes Hebard, 1930 and Pseudocalolampra Roth & Princis, 1971 are insufficiently known and a detailed redescription of their morphology allows us to elucidate their phylogenetic position in the subfamily Epilamprinae.

Remarks: The genus Morphna includes relatively large and wide cockroaches (Figs 1, 3) in comparison with the vast majority of Epilamprinae. The genus is characterized by the structure of its hind tarsi (Figs 14, 15): metatarsus slightly shorter or about as long as other segments combined, with large euplantula along lower margin, tarsal spines few or absent.
Species included: As given in Beccaloni (2014), with the addition of M. indica Anisyutkin in Anisyutkin & Yushkova, 2017 and M. srilankensis Anisyutkin in Anisyutkin & Yushkova, 2017.

Genus Morphnodes Hebard, 1930
Type species: Epilampra vasta Walker, 1868, by original designation.
Remarks: The genus Morphnodes was described as closely related to Morphna, but differs from it as follows: “Pronotal disk with a weak to moderately developed impression latero-cephalad. Tegmina showing distinct distal truncation. Hind metatarsus biseriately spined ventrad.” (Hebard, 1930: 93). Later, Morpnodes was synonymized with Pseudophoraspis Kirby, 1903 by Princis (1958). It was argued that the type species of Morphnodes, E. vasta, belongs to the genus Pseudophoraspis as stated by Shelford (1910). It must be noted that Shelford (1910: 12) did not discuss the taxonomical position of E. vasta, but only listed this species under the genus Pseudophoraspis. In 1967 Princis listed E. vasta in the genus Rhabdoblatta Kirby, 1903 and placed Morphnodes in the synonymy of that genus without giving reasons (Princis, 1967).
Morphnodes goliath (Shelford, 1906), redescribed below, is similar to Morphna maculata, but differs from this and other representatives of the genus Morphna in the structure of the hind tarsi – a character mentioned by Hebard in the original description of the genus Morphnodes. Morphnodes goliath differs from Rhabdoblatta praecipua (Walker, 1868), the type species of the genus Rhabdoblatta (see redescription in Anisyutkin, 2014), and other species of this genus (Anisyutkin, 2000, 2003) in the presence of a well developed “dorsal outgrowth” of the apical part of sclerite L2D (Figs 56-61) and in the structure of fore and mid tarsi: presence of large euplantulae and absence of any spines (Figs 46-47). In all representatives of Rhabdoblatta known to the author all metatarsal euplantulae are small and apical. Morphnodes goliath is similar to representatives of the genus Pseudophoraspis in the presence of a “dorsal outgrowth” on the apical part of sclerite L2D, but differs from species of Pseudophoraspis in the shape of the “dorsal outgrowth”. In M. goliath the “dorsal outgrowth” is short and directed upward (Figs 56-61, d.o.), in contrast to the long and cranial-directed “dorsal outgrowth” of Pseudophoraspis species (see Anisyutkin, 1999; Wang et al., 2013). The head structure is also different: in species of Pseudophoraspis the facial part of the head has a distinct longitudinal impression (see Anisyutkin, 1999; Wang et al., 2013). The apical part of sclerite L2D in Pseudophoraspis fruhstorferi Shelford, 1910 and P. tramlapensis Anisyutkin, 1999 have no “dorsal outgrowth” (Anisyutkin, 1999; Wang et al., 2013), but these species probably belong to another genus.
Taking into account the aforementioned, I prefer to restore the genus Morphnodes from synonymy. To clarify the status of the genus Morphnodes, it is necessary to redescribe the type species, Epilampra vasta.
The genera Morphna and Morphnodes are similar in appearance and in the structure of the male genitalia. They are probably sister-groups with the following synapomorphies: (1) wide costal field of tegmina; (2) fore and mid tarsi with large euplantulae; (3) fore and mid tarsi with reduced spines; (4) “dorsal outgrowth” of apical part of sclerite L2D large and directed upward (large and directed cranially in Pseudophoraspis).
A species with a similar venation of the tegmina was described from the Paleocene (Vršanský et al., 2013).
In the catalogues of Princis (1967) and Beccaloni (2014) the date of publication of Hebard's paper is incorrectly given. Volume 81 of the Proceedings of the Academy of Natural Sciences of Philadelphia for the year 1929 was in fact published in 1930, as stated on the first page of the issue.
Included species: Morphnodes vasta Walker, 1868, M. imperatoria (Stål, 1877), M. goliath (Shelford, 1906), M. miranda (Shelford, 1906).

Remark: This species was described on the basis of one male from Mt Matang in northern Borneo (Shelford, 1906). The holotype (not examined) is kept in the University Museum of Oxford (Beccaloni, 2014).
Genus Pseudocalolampra Roth & Princis, 1971
Type species: Epilampra pardalina Walker, 1868, by original designation.
Remarks: This genus was described on the basis of two species from Africa: P. pardalina Walker, 1868 (from Kenya to Botswana) and P. inexpectata Roth & Princis, 1971 (Kenya). Later, P. pilosa Grandcolas, 1993 from Madagascar was added (Grandcolas, 1993).
There are several types of armament along the lower margin of the tarsus. In one of the most common types, two more or less symmetrical rows of spines are present along the lower margin of the tarsus. Each of the two rows of spines (interior and exterior) is situated on a more or less developed longitudinal elevation. These elevations are symmetrical. In my opinion this is a plesiomorphic state, at least for the Blaberidae. In a derived state, one of these elevations is displaced laterally and consequently the corresponding row of spines is displaced to a lateral position (see Anisyutkin, 1999: figs 7-8). This character state is probably a synapomorphy of several genera of Epilamprinae: Calolamprodes Bey-Bienko, 1969, Paracalolamprodes Anisyutkin, 2015 and Pseudocalolampra.

Genus Colapteroblatta Hebard, 1919
Type-species: Colapteroblatta compsa Hebard, 1919, by monotypy.
Remarks: The genus was described as monotypical, on the basis of 1 male, 7 females and 3 larvae (Hebard, 1919). The morphology of external structures was described in detail in the original description. The male genitalia of C. compsa were illustrated by Roth (1971). Later, the genera Poroblatta Hebard, 1919, Acroporoblatta Hebard, 1919 and Nauclidas Rehn, 1930 were synonymized under Colapteroblatta by Roth & Gutiérrez (1998).
Colapteroblatta compsa Hebard, 1919
Figs 8-9, 85-105
Material examined: MHNG; 1 male; N. Colombia, Dept. Magdalena, N. Sierra Nevada de Sta. Marta, San Lorenzo, 2200 m; 18.-24.08.1985; coll. H.G. Müller, “am Wegrand, aus der Vegetation”. – MHHG; 1 female; same data as for the male, but 22.08.1985, “am Wegrand, unter Stein”.
Remarks: The original description (Hebard, 1919) and the data of Roth (1971) and Roth & Gutierrez (1998) are sufficient and a re-examination of the types is therefore not necessary. The type material (not examined) is probably kept in entomological collection of Academy of Natural Sciences of Drexel University (former Academy of Natural Sciences of Philadelphia). The type locality is “San Lorenzo, Sierra Nevada de Santa Maria, Magdalena, Colombia” (Hebard, 1919), i.e. the specimens redescribed below were collected not far away from the type locality. The following supplementary details can be given.
