Neotrichia abbreviata Flint 1983

Neotrichia abbreviata

This species appears to be most closely related to N. bifida Flint from Surinam. It is easily distinguished because the clasper is not bilobed as it is in N. bifida.

ADULT.—Length of forewing, 2 mm. Color in alcohol, brown.

Male Genitalia: Ninth segment with anterior margin evenly rounded; posterior margin with a sclerotized, pointed lobe dorsally. Tenth tergum membranous. Subgenital plate truncate apically; apparently with a long appendage tucked between bases of claspers. Bracteole membranous, enlarged apicad. Claspers short, apical half black, virtually truncate in lateral and ventral aspects. Aedeagus with a spiral process; apical portion long, with a long internal tubule ending in a shallow U-shaped cup.

MATERIAL.—Holotype (male): BRAZIL, EDO. SANTA CATARINA, Nova Teutonia (27°11′S, 52°23′W), 300–500 m, Nov 1963, F. Plaumann, USNM Type 100517.
