Stirellus yeongnamensis ( Kwon & Lee, 1979) n. rec., comb. nov.

( Figs. 27–29 )

Doratulina yeongnamensis Kwon & Lee, 1979: 100 , plate I; Lee, 1979: 331, Figs. 224–226.

Length. Male: 3.0– 4.3mm; female: 3.4–4.8mm.

Color. General color yellow green throughout ( Figs. 27–28 ). Frontoclypeus stramineous with fuscous arcs from lateral frontal suture reaching only part way across ( Figs. 27 F, 28F).

Body. Head nearly subequal in width to pronotum, subconical, anterior margin rounded to face, acutely angled ( Figs. 27 A–E, 28A–E). Vertex nearly as long as width between eyes or somewhat longer ( Figs. 27 A–E, 28A–D). Ocellus next to eye on anterior margin ( Fig. 28 E). Eye relatively large ( Figs. 27 A–E, 28A–E). Anteclypeus nearly parallel-sided, extending beyond normal curve of genae ( Figs. 27 F, 28F). Pronotum median length nearly as long as median length of crown. Mesonotum and scutellum shorter than pronotum ( Figs. 27 A–E, 28A–D). Forewing macropterous, sometimes exposing apex of abdomen ( Figs. 27 A–E, 28A–E).

Male. Pygofer side without macrosetae, apex as in Fig. 29 A. Subgenital plate slightly concave laterally, macrosetae not uniseriate laterally ( Fig. 29 D). Style narrow, apophysis digitate, laterally curved ( Fig. 29 E–G). Connective stem shorter than arms ( Fig. 29 H). Aedeagal shaft bent at near base, straight, tip slightly curved dorsad, parallel to aedeagal base ( Fig. 29 I–J).

Female. Hind margin of seventh sternum nearly straight ( Fig. 28 G).

Distribution. Korea; China (Fujian, Guangdong, Guangxi, Hainan, Sichuan, Yunnan, Zhejiang).

Remarks. This species was described from the following specimens from Korea with the following data: “Holotype Ƌ, Whasan, IX 1974; allotype ♀, the same with holotype, and paratypes: 15Ƌ, 18♀, the same with holotype and allotype; Taegu, 1♀, 24, VII, 1971; Samsan near Taegu, 1♀, 15, VI, 1975.”. The types have not been examined and the identity of the species is based on the figures of Kwon & Lee (1979). This species is similar to S. dindorensis ( Pruthi, 1930: 38, plate III, 6 & 6a, text-fig. 51–53), but differs in having the male pygofer without macrosetae. This species is also similar to S. lahorensis (Distant) , but the latter has a longer and more acute vertex (see Khatri & Webb, 2010, Fig. 24 .)
