Name
Leucotrichia padera Flint, 1991 – Wikispecies link – Pensoft Profile
- padera Flint, 1991: 41 [Type locality: Colombia, Dpto. Antioquia, Quebrada Espadera, 7 km E Medellín, road to Sta. Elena; NMNH; male].
Diagnosis
This species is most similar to Leucotrichia brochophora, Leucotrichia lerma, and Leucotrichia rhomba sp. n. All four species share a similar form of the apex of the phallus, sternum VIII, and segment IX, as discussed under Leucotrichia brochophora. Leucotrichia padera differs from these species by the presence of the dorsal arm of the subgenital plate (Fig. 32A), which is absent in the other 3 species. It can also be recognized by the shape of the ventral arm of the subgenital plate in ventral view, which appears large and obovate with a rounded apical emargination (Fig. 32D).
Description
Male. Length of forewing 3.0 mm (n=1). Head unmodified, with 3 ocelli; antennae unmodified. Dorsum of head cleared, brown; thorax brown with light yellow setae dorsally, light brown ventrally; leg segments with brown setae. Forewings covered with fine brown setae with 2 broad patches of light yellow setae, apex with dark brown setae. Genitalia. Abdominal sternum VII with elongate mesoventral process curving dorsad. Sternum VIII in ventral view with posterior margin concave. Segment IX anterolateral margin convex, posterolateral margin straight; in dorsal view anterior margin concave, posterior margin concave. Tergum × with dorsal sclerite small, reniform; ventral sclerite subdeltoid; membranous apex suborbicular. Subgenital plate elongate, mildly sinuate, extending dorsally along posterior edge of tergum × ventral sclerite; with dorsal arm digitate, apex enlarged; ventral arm with basal projection, broadest mesally, apex slightly hooked dorsad, in ventral view obovate with rounded apical emargination. Inferior appendage broadest basally, apex hooked dorsally, bearing single dorsal spine; in ventral view with basal projection on inner margin, apically digitate. Phallus apex bearing pair of elongate dorsolateral sclerites and internal ventral apodeme.
Material examined
Holotype male: COLOMBIA: Antioquia: Quebrada Espadera, 7 km E Medellín, road to Santa Elena, 6.iii.1984, C.M. and O.S. Flint, Jr. (USNM 104526) (NMNH).
Etymology
Presumably named for Quebrada Espadera, the location where the holotype was collected.
