Diagnostic characters.

Male. Body pale green. Anal point taper-shaped and tapering towards the sharp apex, bearing lateral setae and microtrichia. Gonostylus thick, blade-shaped projection. Superior and inferior volsellae absent. The conjunction of gonostylus and gonocoxite shrunken and obviously tapered. Gonostylus short, with a weak projection at base, almost as long as gonocoxite. Pupa. (Fig. 5 A–F) Sternite I with only spinose anterolateral tubercles; hook row medially interrupted; segment VIII without comb or spur.

Description.

Pupa [n = 1] Total length 6.55 mm. Cephalothorax brown; abdomen pale brownish.

Cephalothorax (Fig. 5A, C–D). Frontal setae 45 µm long, fine, arising subapically from conical, 130 µm long cephalic tubercles. Thoracic horn (Fig. 5C) plumose, with numerous fine branches; basal ring oval. Thorax granulose dorsally, more densely granulose anteriorly. Prealar tubercle low, rounded. Scutal tubercle prominent. Wing sheath without nose; pearl row absent. Two short precorneals, 2 short antepronotals and 4 dorsocentrals present.

Abdomen (Fig. 5B, E–F). Tergite I (Fig. 5E) bare; II with posteromedian group of small points; III-VI with transverse, posterior band of spinules; VII with a pair of anterior patches fine shagreen; VIII with a pair of anterior and posterolateral patches of shagreen. Hook row widely interrupted medially. Conjunctives bare. Pedes spurii A present on segment IV; pedes spurii B present on segment I and II. Sternite I (Fig. 5B) with spinose anterolateral tubercles. Segment VIII without posterolateral comb or spur. Segment II-IV with 3 strong L setae; V-VII with 4 LS setae, VIII with 5 LS setae.

Anal lobe (Fig. 5F) 1.74 × as long as broad, with complete fringe of 70 lamelliform setae. Genital sac 300 µm long, extending beyond anal lobe.

Distribution.

China (Hubei), Russian Far East; Afghanistan; Lebanon; Europe (Gemary, Poland, Yugosiavia, Romania, France, Belgium, Spain, Italy).

Remarks.

The species was recorded in China by Wang S. (1977). The Chinese specimens of pupal stages mainly agree with the description of Langton (1991), but fringe setae of anal lobe of specimens from China (70) more than from Europe (45-59).
