Ordo: Trichoptera
Familia: Hydroptilidae
Genus: Leucotrichia
Name
Leucotrichia dinamica Bueno-Soria, 2010 – Wikispecies link – Pensoft Profile
- dinamica Bueno-Soria, 2010: 23 [Type locality: Mexico, Distrito Federal, Delgación Magdalena-Contreras, Parque “Los Dinamos”; CNIN; male].
Diagnosis
Leucotrichia dinamica is distinct from all other species in the genus due to the presence of the large scissor-like apical sclerites on the phallus apex (Fig. 16F). The semielliptic sclerite found on the basal loop of the phallus midlength complex is also unique to Leucotrichia dinamica.
Description
Male. Length of forewing 5.1 mm (n=1). Head unmodified, with 3 ocelli; antennae unmodified. Color in alcohol brown. Genitalia. Abdominal sternum VII with acute mesoventral process with apex enlarged in ventral view. Sternum VIII in ventral view with posterior margin concave. Segment IX anterolateral margin produced dorsolaterally, posterolateral margin irregular; in dorsal view anterior margin concave, posterior margin straight. Tergum × with dorsal sclerite simple; ventral sclerite semielliptic with tridentate posterior margin; membranous apex truncate. Subgenital plate with dorsal arm slender, arched mesally, apex slightly hooked dorsad; in ventral view, ovate and produced apically with small emargination; ventral arm digitate, apex slightly hooked dorsad, in ventral view oval. Inferior appendage dorsomesally “humped,” apex acute, bearing single dorsal spine; in ventral view with elongate basal projection strongly bent inward, apex strongly curved outward. Phallus with basal loop with mesal semielliptic sclerite and removed from “windows,” apex bearing pair of elongate internal sclerites and pair of scissor-like apical sclerites.
