Genus Sinogodavaria gen. nov.
Type species.
Sinogodavaria multiformis sp. nov.
Diagnosis.
Supra-antennal setae absent; flagellomere 1 not elongate; costa of female thickened; wing vein Rs with several fine setulae along upper side; vein Rs deflected slightly at the junction with vein M1; vein R2+3 absent; tip of vein R4+5 not enlarged; hind tibia with an antero-apical seta but without an antero-basal seta; male hypandrium without dense microsetae; aedeagus with a long, curled sclerotized process.
Description.
Head. Frons generally broader than long. Median furrow present, vestigial. Supra-antennal setae absent. First and second rows of setae convex. Flagellomere 1 globose; arista sub-apical. Palpus oval, with apical setae and ventral setulae.
Thorax. Propleuron of thorax with three ventral setae, two posterior setae, and scattered setulae. Anepisternum with fine setulae on upper part. Notopleura with four setae, the second being smaller than the others. Scutellum with an anterior pair of small setulae and a posterior pair of setae.
Legs. Fore tibia with a dorsal seta near basal two fifths and several small setulae below it. Mid tibia with the normal basal pair of setae and an antero-apical seta. Hind tibia with two dorsal longitudinal setal palisades, one antero-apical seta, one robust ventral spur and a series of weak posterior and postero-dorsal spurs.
Wing. Costa usually extending to half of wing length. Wing vein Rs with several fine setulae along upper side. Female costa thickened around junction with vein R1 or at the first section of costa. Vein Sc reaching vein R1. Axillary ridge with 4-6 long, black, feathered setae. Haltere yellowish brown, knob black.
Abdomen. Female without tergite VII. Left side of epandrium slender, rounded apically; right side of epandrium large, triangular. Hypandrium with ventrally directed outer lobe covered with rounded spinuli. Aedeagus dark brown, supported by aedeagal apodeme; its left plate with a long, curled, sclerotized process. Anal tube short.
Etymology.
The genus name is derived from Sino and Godavaria and refers to the locality and to the relationship with the genus Godavaria Brown.
Distribution.
China (Liaoning, Hebei, Shaanxi, Sichuan).
Recognition.
In Disney’s (1994) male and female keys to genera, the new genus runs to couplets 9 (males) and 119 (females), respectively, both Borophaga Enderlein, 1924. There is no further division of the genus Borophaga in these keys. In the modified key to the Borophaga group ( Bänziger and Disney 2006), the new genus runs to couplet 3 as Peromitra Enderlein, 1924 and Latiborophaga Brown, 1992. Sinogodavaria gen. nov. is distinguished from Peromitra by a subcircular and non-erect anterior ocellus and thickened costa of the female wing. It differs from Latiborophaga by the more-or-less straight vein Rs and the absence of an antero-basal seta on the hind tibia. It differs from the genus Chaetogodavaria Liu, 1996 by the absence of a long seta on the anepisternum ( Liu 1996). In consideration of new data, the following modifications of the male and female keys to genera by Disney (1994) are proposed.
Partial modification of the key to genera (males) by Disney (1994)
Partial modification of the key to genera (females) by Disney (1994)
