Leucotrichia inflaticornis Botosaneanu, 1993  Figs 3B, 24

inflaticornis  Botosaneanu, in Botosaneanu and Alkins-Koo 1993: 10 [Type locality: Trinidad, 2nd. order stream at "La Laja", catchment of Rio Guanapo; ZMUA; male; larva, case]. - Botosaneanu and Sakal 1992: 201 [biology].

Diagnosis.

Leucotrichia inflaticornis  can be separated from other species in the genus by the inflated basal segments of the antennae (Fig. 3B) for which it was named, and the lack of mesoventral process on sternum VII. Additionally, the phallus apex bears 4 pairs of distinct dark spines.

Description.

Holotype pharate adult, abdomen missing, genitalia redescribed from Botosaneanu and Alkins-Koo (1993). Male. Length of forewing 1.2 mm (n=1). Head unmodified, with 3 ocelli; antennae scape normal, next 5-6 basal flagellum broadened similar to that of Leucotrichia pictipes  . Color in alcohol brown. Genitalia. Abdominal sternum VII with mesoventral process not apparent. Sternum VIII in ventral view with posterior margin with V-shaped concavity. In dorsal view anterior margin of segment IX convex, posterior margin concave. Membranous apex of tergum × suborbicular. Subgenital plate apically bilobed, with small pointed projection at base of each lobe. Inferior appendage apex truncate; in ventral view entirely fused. Phallus with median complex present but only slightly developed, apex bearing 4 pairs of symmetrically arranged stout, dark spines.

Material examined.

Holotype male: TRINIDAD: 2nd order stream at "La Laja", catchment of Rio Guanapo (in alcohol) (UMSP000140327) (ZMUA).

Etymology.

Specific epithet refers to the inflated appearance of basal antennal segments.
