Diagnosis and notes

Chrysopa dubitans is similar to C. formosa by the similar dark marking on frons and vertex, but it can be distinguished by pale green subcostal veinlets in forewing and the male sternum 9 (S9) with two pairs of large gonocristae (gcr) at lateral margins, consisting of small and large teeth ( Tjeder 1936: plate XIV A–L).

Redescription

Measurements (♂ n=7, ♀ n=5). Forewing: length ♂ 10.7–13.0 mm, ♀ 12.0– 14.5 mm, width ♂ 4.0– 5.1 mm, ♀ 4.6–5.7 mm; hindwing: length ♂ 10.0– 12.5 mm, ♀ 11.0–13.0 mm, width ♂ 3.4–4.2 mm, ♀ 4.0– 4.9 mm; body length: ♂ 7.2–8.6 mm, ♀ 7.5–8.5 mm.

Head ( Figs 28A–B, D View FIGURE 28 ). Vertex moderately raised, with two dark spots at proximal 1/2, rounded in frontal view. Postorbital sclerite unmarked. Frons yellow, with a transverse dark spot around the base of antennal toruli, and medially with a dark spot below interantennal marking. Clypeus yellow, distally with a few long yellow setae. Labrum yellow, covered with short yellow setae. Genae yellow, with a dark spot. Maxillary and labial palpi dark brown, yellow at proximal 1/2, terminal segment wholly brownish yellow, covered with short dark brown setae. Antennal toruli yellow. Antennal yellow, unmarked, covered with short pale yellow setae; scape yellow, unmarked; pedicel yellow, distally dark brown; flagellum yellow.

Thorax ( Figs 28D–E View FIGURE 28 ). Pronotum slightly wider than long (length 0.47–0.68 mm, width 0.93–1.03 mm), yellow, covered with short dark brown setae, laterally with mixed short black and yellow setae. Meso- and metanotum yellow, sparsely covered with short pale yellow setae.

Legs ( Fig. 28E View FIGURE 28 ). Pale yellow, unmarked, covered with short brownish setae. Pretarsal claws with distinct basal dilation, less than 1/3 of the length of claws hook, quadrate at base ( Fig. 28C View FIGURE 28 ).

Wings ( Figs 27A–B View FIGURE 27 ). Forewing: Costal area relatively narrow at both ends, slightly wider at the longest subcostal veinlets (4–13). Subcostal area with three to four crossveins below pterostigma; basal subcostal crossvein (bsx) dark brown. Longitudinal veins pale green except subcostal veinlets narrowly dark brown at extreme base, distal branches of anal veins dark brown (pale green in some specimens), crossveins of intramedian and intracubital cells dark brown (pale in some specimens). Pterostigma pale brown. 11–14 radial cells (r cell); radial crossveins proximally dark brown. Four Banksian cells (b cell); four lower Banksian cells (b’ cell). Basal crossvein between Rs and M (r-m 1) oblique, meets at subdistal margin of im cell. Two series of gradates, both meet psm; four to five inner gradates (ig) and seven to eight outer gradates (og). Two intramedian cells; first intramedian cell (im1) ovate. Second (m2) and third (m3) median cells of similar size. Three intracubital cells (two closed); first cubital crossvein proximal to second mediocubital crossvein (m-cu2); first (icu1), second (icu2) and third (icu3) intracubital cells of similar size. Hindwing: Veins pale green. Costal area narrow, proximal 1/2 of subcostal veinlets 1–11 dark brown. Subcostal area with three crossveins below pterostigma. Pterostigma pale brown. 10–13 radial cells (r cell). Four Banksian cells (b cell); four lower Banksian cells (b’ cell). Two series of gradates, both meet psm; five inner gradates and six to seven outer gradates.

Abdomen ( Figs 28D–E View FIGURE 28 ). Tergum pale green, covered with short yellow setae. Sternum pale green, covered with short yellow setae, except S5–7 with dark brown setae.

Male genitalia ( Figs 29A–F View FIGURE 29 ). Tergum 8 (T8) quadrated in lateral view. T9+ectoproct rounded in lateral view, covered with brown setae. Dorsal arm of apodeme (da) on ectoproct arcuated, not extending beyond callus cercus; submarginal apodeme (sa) of S9 straight. Callus cerci (cc) oblong, with 32–35 trichobothria. S8 subtrapezoidal in lateral view; S9 triangular, slightly longer than T9+ectoproct in lateral view; a pair of large gonocristae (gcr) at lateral margins of S9, consisting of small and large teeth. Gonarcus (gon) broad, arcuated with lateral shorthorn. Entoprocessus (ent) small, with lateral dorsal shorthorns. Arcessus (arc) absent. Pseudopenis arcuated, pointed distally. Gonosetae (gst) in lateral pockets below gonarcus in lateral view. Tignum absent. Hypandrium internum (hi) V-shaped with small and straight comes (c) in dorsal view.

Female genitalia ( Figs 29G–K View FIGURE 29 ). Tergum 8 (T8) subquadrate in lateral view. T9+ectoproct rounded in lateral view. Sternum 7 (S7) quadrate in ventral view. Gonaphophyses lateralis (gl) oblong in lateral view. Callus cerci (cc) oblong, with 35–37 trichobothria. Subgenitale (sg) broad, rounded, bilobed distally, heavily sclerotized, membrane above lobes with crescent-shaped. Spermatheca (sm) small, rounded, doughnut-shaped, with distinct median rounded invagination (inv) in lateral view. Spermathecal duct (sd) long, cylindrical, double-coiled, attached to bursa copulatrix (bc).
