1. Impatiophila yapingi species group, new

Diagnosis. Anteromost, posterior sensillum of cibarium not shorter than twice length of posteromost, medial sensillum ( Fig. 3 A). Patch of dense, small setae or stout setulae present on caudoventral portion of epandrium ( Fig. 5 B). Ovisensilla on ventral margin of oviscapt valve distally increasing or nearly constant in size ( Fig. 6 E). Subapical, trichoid ovisensillum of oviscapt valve stout, longer than apical, peg-like ovisensillum ( Fig. 6 E). Spermathecal capsule wider than long, apically somewhat round or flat in lateral view ( Fig. 6 M).

Common characters. Cibarial, posterior sensilla slightly curved anteriad. Labellum with 6 pseudotracheae per side (small variation seen in I. trifurcatosternata ). Hindleg tarsomeres I‒IV each with 1 black, apically blunt, stout spine at outer apex on underside ( Figs. 3 K, 12A; unknown for I. limbicostata ). Distal margin of surstylus deeply concave in ventral 2/3 (except for I. quadrangulata : moderately concave). Paramere more or less roundish on apical margin (except for I. quadrangulata : quadrangular as a whole) in lateral view. Aedeagal basal process longer than 1/2 of paramere. Oviscapt valve horizontally expanded at apical portion (except for I. yangi and I. forcipivalva : not distinctly expanded); lateral ovisensilla tightly arranged in a nearly straight (in ventral view) row on margin of apicolateral flap (except for I. yangi and I. forcipivalva ); ovisensilla on ventral margin of valve entirely arranged at nearly equal intervals.
