Leucotrichia sarita Ross, 1944 – Wikispecies link – Pensoft Profile
- sarita Ross, 1944: 274 [Type locality: United States, Texas, Balmorhea, along stone irrigation flume; INHS; male]. — Flint 1970[1]: 9 [male, larva, case, distribution].
Diagnosis
Leucotrichia sarita is similar to Leucotrichia fairchildi, Leucotrichia imitator, and Leucotrichia pictipes. Leucotrichia sarita is distinct from Leucotrichia imitator and possesses a more modified head, due to the presence of eversible posterolateral warts (Fig. 4D). It does not have any of the further head modifications found on either Leucotrichia fairchildi or Leucotrichia pictipes. The presence of the membranous lobes on the phallus terminating in sclerotized spines also distinguishes Leucotrichia sarita from the other 3 species of the pictipes species group.
Description
Male. Length of forewing 2.1–3.0 mm (n=306). Head with posterolateral wart large, eversible, with membranous lobe beneath, with 2 ocelli; antennae unmodified. Dorsum of head brown with yellow setae; thorax brown with dark brown and yellow setae dorsally, brown ventrally; leg segments with brown setae. Forewings covered with fine dark brown setae with stripe of yellow setae running the length of basal 1/3 and scattered patches of yellow setae near apex. Genitalia. Abdominal sternum VII with mesoventral process absent, in its place a few dark, prominent setae. Sternum VIII in ventral view with posterior margin concave. Segment IX anterolateral margin convex, posterolateral margin irregular; in dorsal view anterior margin concave, posterior margin concave. Tergum × with dorsal sclerite slender; ventral sclerite semielliptic with crenulate posterior margin; membranous apex with dorsal and ventral lobes. Subgenital plate with dorsal arm not apparent; ventral arm hollow, subtriangular, with basal projection, curved dorsad, in ventral view lanceolate. Inferior appendage straight, digitate, bearing single dorsal spine; in ventral view broadly fused, apex rounded, with small apical “lip” (Fig. 39D). Phallus apex bearing pair of mesolateral lobes ending in sclerotized spine and numerous small apical spines on dorsal and lateral surface.
