Amurinocellia australis Liu, H. Aspöck & U. Aspöck , sp. nov.

( Figs. 4–5 , 16–18 )

Diagnosis. This species is characterized by the triangular yellowish markings on the terga of the pregenital segments and by the female eighth tergite strongly produced into a pair of acutely pointed processes on the posteroventral corners.

Description. Female. Body length with ovipositor 15.2 mm, body length without ovipositor 10.9 mm; forewing length 8.9 mm, hindwing length 8.1 mm.

Head ( Fig. 4 ) subquadrate, black, with anterior clypeus pale yellow. Compound eyes blackish brown. Antennal sclerite (torulus) pale yellow, antennae brownish with scape and pedicel pale yellow. Mouthparts brown.

Thorax blackish brown; pronotum with anterior margin yellow, anterior half medially with a pair of hooklike brownish markings; meso- and metanota anteriorly with a yellowish median spot posteriorly connected to yellowish scutellum, lateral portions of meso- and meta thorax mostly brown ( Fig. 5 ). Legs yellow with yellowish setae except for coxae brown; apices of femora and middle portions of tibiae slightly darker. Wings hyaline, pterostigma brown, veins brown, longitudinal veins proximally pale yellow except for anal veins. Anterior branch of Rs with one forked vein and one simple vein running to wing margin.

Abdomen blackish brown; each pregenital segment dorsally with a triangular yellowish marking posteriorly, ventrally with a narrow yellowish stripe; genital segments blackish brown with ectoproct and ovipositor yellowish brown ( Fig. 4 ). Seventh sternite ( Figs. 16–17 ) in lateral view subtrapezoidal with posteroventral corner strongly pointed, in ventral view posterior margin arcuately incised, forming a pair of obtuse processes. Eighth tergite ( Figs. 16–17 ) strongly expanded ventrad, nearly enveloping ventral portion of eighth abdominal segment, with posteroventral corners strongly produced into a pair of acutely pointed processes, which are directed posteriorly. Subgenital plate absent. Ectoproct ( Fig. 16 ) in lateral view subquadrate, slightly narrowed toward apex. Atrium bursae ( Fig. 18 ) rounded, slightly pointed dorsad; sacculus bursae bulbiformed; receptaculum seminis short, with a pair of ovoid glandulae receptaculi subdistally.

Male. Unknown.

Material examined. Holotype Ƥ [preserved in alcohol], CHINA: Zhejiang Province, Lin-an County, Tianmushan, 30°20'N, 119°26'E, 3.V.1980, Chikun Yang ( CAU).

Distribution. China (Zhejiang).

Etymology. The specific epithet ‘ australis ’ refers to the geographic distribution of the new species in the southern part of China.

Remarks. Although the new species is described based on a single female, it can be easily distinguished from the other two Amurinocellia species by a number of general and genitalic characters. It differs from A. calida by the female seventh sternite with a pair of obtuse posterior processes and the female eighth tergite with the posteroventral corners strongly produced into a pair of acutely pointed processes, while it differs from A. sinica by the absence of the yellowish markings on the lateral portions of the meso- and meta thorax, by the triangular yellowish markings on the terga of the pregenital segments, and also by the modification of the female eighth tergite. In A. calida , the posterior processes of the female seventh sternite are triangular and the female eighth tergite is feebly produced into a pair of obtuse processes. In A. sinica , the meso- and metathorax possess broad yellowish markings on its lateral portions, the abdominal markings are all transversely band-like, and the posteroventral processes of the female eighth tergite are short and obtuse.
