Diagnosis.

Adult (Fig. 1c) with wing expanse 14.0-15.0 mm. This species is similar to Halolaguna sublaxata Gozmány, 1978 superficially by sharing small and rounded discal spot and relatively large fold and discocellular spots. It can be separated from the latter by the valva broadly rounded apically, the relatively short gnathos slightly shorter than the uncus, and the juxta with postero-lateral lobes shorter than the juxta in the male genitalia (Fig. 3c). In Halolaguna sublaxata , the valva is narrow and thin apically, the slender gnathos is distinctly longer than the uncus, and the postero-lateral lobes of the juxta are longer than the juxta.

Female genitalia (Fig. 4b): Eighth sternite bearing dense setae, with caudal margin slightly emarginated at middle. Anterior apophyses about 3/4 length of posterior apophyses. Ductus bursae about four times length of corpus bursae, long and heliciform; ductus seminalis slender, arising from basal 1/8 of ductus bursae. Corpus bursae nearly rounded; two small papillate signa placed posteriorly, with dense granules; one big rhombic signum placed at middle of corpus bursae, with a nearly triangular horizontal fig arising medially.

Distribution.

China (Chongqing, Guangdong, Guangxi, Guizhou).

Remarks.

Halolaguna guizhouensis was described by Wu (2012) based on two male specimens from Guizhou. The valva of this species is not distinctly narrowed distally, whereas the valva of its congeners is obviously narrowed to pointed apex. However, the venation of this species is consistent with that of the type species. The female is described here for the first time.
