Description

Docidiadia, new genus

DIAGNOSIS: Head round. Flagellum 14­segmented. First flagellomere length slightly more than width. Fore tibial comb absent. Wing membrane without macrotrichia. C ends beyond tip of R 5; Sc long, ends free; RS base at the middle of R 1; crossveins r­m,

tb, and m­cu in one line; M3 section and base of M fork absent; CuA strongly curved back at the apex. A short. Male 9th tergite without marginal bristles, with one large, acute, triangular medial appendage and two small lateral ones; gonostyli do not bifurcate at apex.

TYPE SPECIES: Docidiadia burmitica, n.sp.

ETYMOLOGY: The name is a feminine anagram of Diadocidia.

COMMENTS: The genus is close to Diadocidia Ruthe, but differs in having the first flagellomere short; wing membrane without macrotrichia, Sc ending free, base of RS rather distal, M3 section and base of M fork reduced; CuA curved at apex rather than with two straight sections; and male tergite IX narrow, triangular, and with two lateral appendages. Diadocidia consists of two subgenera and includes 10 Holarctic species (Chandler, 1994; Laštovka and Matile, 1972; Polevoi, 1996; Wu, 1995; Zaitzev, 1994) and a Neotropical one (Edwards, 1940; Papavero, 1977a), as well as undescribed Australian species (Tonnoir, 1929; Colless, 1963). One species is known from Baltic amber (Evenhuis, 1994).
