The three species of Symmocinae (Autostichidae) known to occur in North America are reviewed, and imagos and male and female genitalia are illustrated. A new genus and new species of Symmocinae are described and novel morphological characters are illustrated.

The Symmocinae (Lepidoptera: Autostichidae) includes 170 species of moths in 42 genera, with highest diversity in xeric areas of the Palearctic Region (Gozmány 1957, 1959, 1963, 1964; Hodges 1983). Larvae are known to feed on decaying plant materials (Gozmány 1963; Griffith 1890; Powell 1960). Three species have been reported from North America: Sceptea aequepulvella (Chambers) (Figs. 1, 5) Oegoconia quadripuncta (Haworth) (Figs. 2, 6), and Symmoca signatella Herrich-Schäffer (Figs. 3, 7), with the latter two species introduced from the Palearctic Region (Hodges 1983; Powell 1960). Specimens of an unknown symmocine, initially collected in Mississippi and later from other states, have been identified here as a new species as well as a new genus.

The classification and phylogenetic position of Symmoca and related genera have been unstable. In recent years, the Symmocinae has been treated as a family (Gozmány 1963), a subfamily of Blastobasidae (Hodges 1983), and a subfamily of Autostichidae (Hodges 1999; Kaila 2004).

Hodges (1999) defined the Autostichidae by homoplasous characters of an articulated gnathos (Fig. 8) and presence of spiniform setae on abdominal terga (Fig. 12). He further defined the Symmocinae by homoplasous characters of a forewing with CuP absent (Fig. 10A), female with retinaculum composed of a series of anteriorly directed scales between CuA and R (Fig. 16), abdominal terga crossed by bands of slender, spiniform setae, sometimes deciduous, and the gnathos forming a mesial hook (Fig. 8).

The purpose of this study is to review and illustrate North American species of Symmocinae and describe novel morphological characters of a new genus and species that may be valuable for resolving the phylogenetic relationships of gelechioid taxa in future studies.


Published figures of 139 species representing 42 genera, including male genitalia of 38 type species, were examined. Figures of male genitalia are lacking for type species of five genera, including Tenieta Gozmány, Hamartema Gozmány, Symmoletria Gozmány, Sceptea Walsingham, and Gigantoletria Gozmány, the latter four described to include species represented only by females.

One to two male and female specimens of the following species were borrowed from the National Museum of Natural History (USNM): Amselina oxybiella (Millière), Aprominta designatella (Herrich-Schäffer), Nestorellus meyricki Gerasimov, and the three species in North America, Sceptea aequepulvella (Chambers), Oegoconia quadripuncta (Haworth), and Symmoca signatella Herrich-Schäffer.

Dissection and slide mounting methods for genitalia followed Clarke (1941), except the preparations were stained in eosin and mounted in euparol. Wing venation slides were made with the same method used for genitalia, except the denuded wing was stained in eosin overnight. A hind leg from each species of the known Symmocinae in North America was cleaned of scales, stained, and slide mounted separately. Whole body mounts of the new species were made following methodology of Lee & Brown (2006), and these were compared with whole body mounts of the following taxa: Agonopterix thelmae Clarke, Antaeotricha humilis (Zeller), Antaeotricha leucillana (Zeller), Autosticha kyotensis (Matsumura), Blastobasis glandulella (Riley), Callima argenticinctella Clemens, Calosima lepidophaga (Clarke), Coleophora cratipennella Clemens, Dichomeris ligulella Hübner, Durrantia piperatella (Zeller), Ethmia longimaculella (Chambers), Ethmia trifurcella (Chambers), Eupragia hospita Hodges, Gelechia albisparsella (Chambers), Gerdana caritella Busck, Glyphidocera democratica (Meyrick), Glyphidocera lactiflosella (Chambers), Inga sparsiciliella Clemens, Homaledra heptathalma Busck, Machimia tentoriferella Clemens, and Pseuderotis obiterella (Busck).

A Leica MZ 125 Stereo-Microscope and Olympus Compound Microscope were used for examining specimens and slide mounts. Images were made with a Leica TCS NT confocal laser scanning microscope, LEO S360 scanning electron microscope, and a Leica stereoscope with Image Pro Plus 5.1 program for auto formatting. For scanning electron microscopy, specimens were air dried and mounted on aluminum stubs with silver paste, coated with gold-palladium, and examined at an accelerating voltage of 5kV. Distributional data are based on publications and on specimens in collections of the Mississippi Entomological Museum (MEM) and USNM.

DNA samples were extracted from two pairs of hindlegs from two pinned specimens of the new species following the protocol for Qiagen's DNeasy Tissue Kit. Five of ten clones could be sequenced and checked in GenBank using the BLAST function to determine the identity of spore-like structures associated with the hindlegs.

  • Distribution. Fifty-seven specimens (52 males, 5 females) have been collected during April–October in the midsouthern states and Kansas (Fig. 23).

  • Etymology. The species epithet is a patronym for Ronald W. Hodges, who first recognized this species as being a new genus and new species.

    Distribution of Spinitibia hodgesi.



    The assignment of Spinitibia to Symmocinae is validated by presence of an unarticulated gnathos, abdominal terga with bands of spines, hooked gnathos, unique form of the female retinaculum, and absence of forewing vein CuP. The forms of the uncus and female genitalia (Fig. 10) are similar to those in other genera of Symmocinae.

    Spinitibia hodgesi is the second known endemic species of Symmocinae in North America. Most specimens have been collected in a variety of dry forests, but 18 specimens have been collected in prairies, cedar glades, inland dunes, and old fields.

    Scanning electron microscopy revealed spore-like structures on the spiniform setae of the hindleg, some of which are imbedded between longitudinal ridges (Fig. 15). DNA sequences from the hindlegs revealed the presence of a basidiomycete mushroom (Russula sp.) in one clone, and basidiomycete yeasts (Cystofilobasidium sp. and Asterotremella sp.) in three clones. However, the spore-like structures are not considered to be of fungal origin, and they are smaller than the smallest yeast cells (Steven Miller personal communication); thus, their identity remains unknown. Similar spore-like structures were detected on the antenna of a specimen of Sceptea aequepulvella borrowed from the U.S. National Museum. Such spore-like structures have not been seen on bodies of a large number of species of Tortricidae and Gelechiidae in the MEM that have been examined previously with scanning electron microscopy.


    We thank Ronald W. Hodges for confirming the undescribed status of Spinitibia hodgesi. We thank John Brown and David Adamski for making loans of specimens from the U.S. National Museum. We thank Richard E. Baird, Mississippi State University, for cloning the DNA samples, and Steven Miller, University of Wyoming, for confirming that the spore-like structures were not of fungal origin. We thank Terrence Schiefer and Gerald Baker for reviewing this manuscript. We thank the staff of Bon Secour National Wildlife Refuge and Noxubee National Wildlife Refuge for allowing collection of specimens on land under their management. Support for collection of specimens and this research was provided by National Science Foundation grants BSR-9024810, DEB-9200856, and DEB-0416078 and by Mississippi Agricultural and Forestry Experiment Station project MIS-6538. Approved for publication as Journal Article No J-11600 of the Mississippi Agricultural and Forestry Experiment Station, Mississippi State University.
