description: Impatiophila Fu & Gao, gen. nov.
Diagnosis. One or two apically blunt, stout spine(s) present at outer apex on underside of hindleg tarsomeres I to IV (Fig. 3 I, K). Dorsal, stout, upturned prensiseta(e) of surstylus more or less separated from others (Fig. 5 E). Ovisensilla on ventral margin of oviscapt valve not more widely spaced in proximal portion than in other portions (Fig. 6 C, G).
Common characters. Eyes red to reddish purple, with thick interfacetal setulae. Frons brown to blackish brown, nearly parallel-sided; ocellar triangle and fronto-orbital plates glossary black. Antennal pedicel cylindrically conical, yellow to brown, blackish brown laterally, with 2 prominent and a few small setae; first flagellomere yellow. Face yellowish brown; carina narrow, relatively flat. Gena narrow, yellowish brown; postgena and occiput black. Palpus apically roundish, with 1 prominent seta apically and several short ones apically to ventrally. Cibarium protruded at anterolateral corners, with 4 anterior sensilla arranged in somewhat irregular quadrangle and 2 pair of sensilla campaniformia. Acrostichal setulae in 8 regular rows. Postpronotal setae 2 (4 in I. actinia comb. nov.), subequal. Prescutellar setae absent. Basal scutellar setae usually diverged from each other; apical scutellar setae cruciate. Mid katepisternal seta as long as or slightly longer than anterior katepisternal one; katepisternum without setulae beside prominent seta near caudoventral corner. Wing apically round, relatively long and narrow, extending much beyond abdominal tip; C1 setae 2; R2+3 slightly curved to costa; R4+5 and M nearly parallel distally. Preapical dorsal setae present on tibiae of all legs; apicals only on tibiae of midlegs; tarsomere Vs of all legs dark, with large claws. Female abdominal tergite VII separated into 2 lateral plates, blackish brown. Epandrium usually truncate ventrally. Surstylus with a row of prensisetae like canine teeth along caudal margin. Cercus separated from epandrium. Hypandrium without paramedian setae, posteriorly fused with gonopods. Gonopods flap-shaped, apically narrowing, close to each other, forming clamp-like structure. Paramere postolaterally fused with gonopod, with sensilla arranged in longitudinal row from subapical to subbasal portion (except I. quadrangulata sp. nov.: in chevroned row). Aedeagus membranous; basal process well developed, sclerotized; apodeme rod-shaped, anteriorly expanded in lateral view.
Type species. Hirtodrosophila yapingi Gao, 2011.
Etymology. Referring to the preference (Latin: -philus) to the genus of their main host plants (Impatiens). Gender: feminine.
Key. The multiple-entry key “ Impatiophila (Diptera: Drosophilidae)” to all species of this genus has been constructed based on a database of morphological characters, and is available from the website “Biological Classification and Identification System (BioCIS: http://biokey.museum.hokudai.ac.jp/Classification/index.jsp)”.
