Comprehensive Description

provided by Smithsonian Contributions to Zoology
Neotrichia elongata

Both this species and N. chilensis have very long ventromesal processes from the ninth sternum, but I can not tell if they are truly homologous. The claspers are more pointed apically in this species, and the aedeagus is totally different in construction, lacking the black spine.

ADULT.—Length of forewing, 3 mm. Color in alcohol, pale brown.

Male Genitalia: Ninth segment with anterior margin produced into a rounded lobe. Tenth tergum membranous. Subgenital plate bearing apically a mesoventral process. Bracteole membranous, very broad. Claspers elongate, slender; with an elongate, slender mesoventral process between them. Aedeagus with a spiral process; apex elongate, tubular, with a darkened internal tubule.

MATERIAL.—Holotype (male): ARGENTINA, PCIA. SALTA, Cañada la Gotera, Rt. 59, km 23.5, 16–17 Oct 1973, O.S. Flint, Jr., USNM Type 100525.

Paratypes: Same data as holotype, 2.
