Gynodiplosis Felt

[ Figs 16 a–i]

Gynodiplosis Felt, 1927a: 383 .

Type species: Gynodiplosis humata Felt , by original designation.

Description. Adult. Antennae in both sexes with 12 binodal flagellomeres, basal node with one, distal with two loops of circumfila [ Figs 16f, i ]. Occipital protuberance absent. Palpus 1-segmented [ Fig. 16g ]. Wing with R 5 curved distally, joining C beyond wing apex; C broken at juncture with R 5; R 1 half-length of wing; Rs not present, M 4 and Cu 1 forming fork [ Fig. 16b ]. Tarsal claws with two teeth on all legs [ Figs 16d, e ].

Male. Terminalia (seen in lateral view only)[ Fig. 16c ]: gonocoxite with bulbous, setulose mesobasal lobe; gonostylus long, cylindrical, gradually tapered, with many setae on distal two-thirds, setulose basally, carinate beyond; aedeagus longer than gonocoxite, cylindrical, curved dorsally, rounded apically; cerci ovoid with many setae; hypoproct incised apically, lobes narrow, each with single seta.

Female. Terminalia in lateral view [ Fig. 16h ]: ovipositor barely protrusible; cerci separate, ovoid, microsetose, with many setae, an apical pair thickened and blunt.

Pupa, larva unknown.

Remarks. This monotypic genus belongs to the supertribe Cecidomyiidi and is notable for the one-segmented palpus, the curved, two-toothed tarsal claws and the female flagellomeres with two nodes and three circumfila, identical to that of the male. It is unplaced to tribe.
