Trichomyia fairchildi Vargas and Díaz­Nájera, 1953

( Fig. 1 )

Trichomyia fairchildi Vargas and Díaz­Nájera, 1953: 154 . Type locality: Mexico, Chiapas, San Cristóbal de las Casas, Cerro Hueytepec. Additional references: Satchell 1956:155; Duckhouse 1973:5 (neotropical Cat.); Ibáñez­Bernal 2000:625 (Mexican Psychodidae list).

Trichomyia fairchildi was described based only on wing characteristics ( Fig. 1 ), the unique structure preserved in a microscope slide by Dr. Alphonse Dampf in 1947. Because the wing characteristics are not useful alone for species recognition, it is necessary to consider it as species inquirenda. Nevertheless, it is important to mention that this specimen shares wing characteristics with Trichomyia urbica Curtis, 1839 (as figured by Vargas and Díaz­ Nájera 1953, and Satchell 1956), such as the broadly rounded wing apex, the radial fork apicad of the wing center, vein r­m present, and the median fork approximately at the level of CuA2.

Material examined: Holotype (wing): Mexico, Chiapas, San Cristóbal de las Casas, Cerro Hueytepec, 14­VI­1926. A. Dampf, col. & pp., 3­IX­1947, slide in Canada balsam: InDRE (PsT­87005).
