Trichomyia Haliday in Curtis 1839

Description

TRICHOMYIA (DICROTRICHOMYIA) DUCKHOUSE, 1978

Dicrotrichomyia Duckhouse, 1978: 204.

Type species: Trichomyia leei Duckhouse, 1965, by original designation.

Species included: Trichomyia bulbosa Duckhouse, 1978; Trichomyia brachypenis Duckhouse, 1978; Trichomyia leei Duckhouse, 1965; Trichomyia lyrata Duckhouse, 1978; Trichomyia quadrispinosa Duckhouse, 1978; Trichomyia trukensis Quate, 1959; and Trichomyia uncinata Duckhouse, 1978.

Comments: Only one synapomorphy for this subgenus was recovered: presence of three supracervical bristles (10-2). Species of the subgenus Dicrotrichomyia have a spiniformandstronglysclerotizedarmofthegonocoxitein the mediodorsal region. In addition, the aedeagus is apically forked, resembling a fork, and the gonostylus is short, robust and apically expanded. The cercus has rod-like apical bristles (Duckhouse, 1978).

The present phylogenetic analysis and Duckhouse’s (1978) work recovered Dicrotrichomyia as monophyletic, with synapomorphies already defined for the group, such as the aedeagus with a bifurcation point at the apex of the gonocoxite arm, in addition to other homoplastic characteristics, including the wing with a medial fork closer to the base than CuA 2; base of R 2 without microtrichia; male genitalia with a long cercus, larger than the epandrium and with differentiated bristles; and gonostylus cylindrical, and hypandrium and gonocoxite separated from each other.
