Genus Austrochrysa Esben-Petersen, 1928

Esben-Petersen 1928: 98; New 1987: 281; Brooks and Barnard 1990: 190.

Type species: Austrochrysa samoana Esben-Petersen, 1928 , by original designation.

Synonym. Scoliochrysa Navás, 1929: 365 ; Banks 1937: 149 (synonymized with Chrysopa Leach ); Brooks and Barnard 1990: 190 (synonymized with Austrochrysa Esben-Petersen ).

Yunchrysopa Yang & Wang, 1994: 69 ; Yang et al. 2005: 329. syn. nov.

Diagnosis. (Adapted from Brooks and Barnard 1990). Forewing length 12–18 mm. Head unmarked or with labrum marked brown, scape unmarked or marked with lateral brown stripe; head width/eye width = 1.60–2.55; scape swollen, elongate; antenna much longer than fore wing. Pronotum with a pair of medio-lateral oval spots; dorsal setae long, pale. Legs unmarked. Forewing narrow or broad (length: width = (2.4–4.0: 1), with pale brown suffusion around most crossveins or black spots on distal cubital cell (dcc), median radial crossveins, base of outer gradates; outer gradates usually black; pterostigma marked with grey spot basally; first intramedian cell long, narrow, quadrangular or ovate; gradates in two or three irregular rows. Abdomen marked or unmarked. Male genitalia: Tergum 9+ectoprocts with deep apico-dorsal invagination; callus cerci ovate, large; trichobothria, large, widely dispersed; sterna 8+9 and ectoprocts sometimes widely separated; sterna 8+9 fused, invaginated apically, gonocristae present, microtholi absent. Tignum present; gonarcus long, narrow; mediuncus trilobed apically; entoprocessus short, narrow or broad, L-shaped; gonosaccus large, circular; gonosetae long, numerous, evenly dispersed. Female genitalia: Tergum 9+ectoprocts without apico-dorsal invagination; callus cerci small, rounded; trichobothria not widely dispersed; sternum 7 straight or slightly convex posteromedially. Subgenitale narrow, bilobed apically, with long basal extension; spermatheca small, narrow; ventral impression shallow or moderate; vela long; spermaduct long, sinuous.

Distribution. China, India, Philippines, Indonesia, Malaysia, Papua New Guinea, Samoa and Fiji.

Remarks. Yunchrysopa was established by Yang and Wang (1994), with Y. tropica as the type species by original designation. We have examined the holotype of the type species and found it has median spots on the pronotum, gonocristae on the male sterna 8+9, the oval callus cerci, the tignum and the L-shape entoprocessus. These characters represent strongly morphological evidence for considering this species belonging to the genus Austrochrysa Esben-Petersen, 1928 . Therefore, Yunchrysopa is herein considered as a junior synonym of Austrochrysa .

Brooks and Barnard (1990) stated that there is an undescribed species of Austrochrysa from Assam ( India) in Natural History Museum, London (NHML). Though we have not examined the specimen in NHML, we believe that the information provided by Brooks and Barnard (1990) is accurate and Austrochrysa also occurs in India because the locality ( China, Xizang, Mêdog) of A. angusta sp. nov. is adjacent to Assam.
