Jembra kuanae Shih, sp. nov.

Jembra kuanae Shih sp. nov. (Figs. 2, 3) Coloration: General color brown (Fig. 2 A). Tegmen without markings (Fig. 2 B); wing hyaline, veins brown, apical area with brown pubescence except apical cells. Two color variations on head (Figs. 2 D, 2E), pronotum and mesoscutellum: dark brown type with irregular dark brown mottles (Fig. 2 E), and yellowish brown type with one obviously inverted and yellowish V-shaped stripe (Fig. 2 D). Structure: Head width: body width: body length= 1:1.6:3.2. Head in ventral view rhombus shaped (Fig. 3 B), as long as wide; head in dorsal view triangular (Fig. 3 A), about 2.6 times as wide as long. Head subequal to pronotum at level of anterior margin, about 1.04:1.0. Frons with a median longitudinal carina and 10 transverse ridges in ventral view (Fig. 3 B). Expanded flagellar base with 4 plate-shaped basiconic sensillae on ventrolateral side. Rostrum nearly extended to apex of middle trochanters. Pronotum width at widest part greater than median length by about 1.5: 1.0. Tegmen densely punctured (Fig. 3 D) with pits about 0.1 mm in diameter; 3 times as long as wide, AM (length of anal margin): PM (length of posterior margin): LT (length of tegmen) = 1.0: 3.0: 3.9. Wing with 3 apical cells (Fig. 3 E). Hind tibia with two lateral spines, distal one about 2.0–2.5 times as long as basal one; apical spines arranged into 2 rows, upper row composed of 11 spines, lower one composed of 12 spines. First hind tarsomere with apical spines arranged in two rows (Figs. 2 C, 3H), upper row composed of 18–21 spines, lower one composed of 7–12 spines. Male Genitalia: Pygofer in lateral view subquadrate (Fig. 3 I), about 1.3 times wider than long; basal margin of pygofer straight downward, then protruding at ventral third; pygofer ventral view oval (Fig. 3 J); dorsal process of pygofer (dp) in lateral view cone like, ventrally directed (Fig. 3 I); ventral process of pygofer (vp) (= genital plate) in lateral view, about 0.7 times longer than posterior margin of pygofer; ventral processes of pygofer in ventral view bilobed, acute at tip and direct mesade (Fig. 3 J). Abdominal segment X cylindrical, subequal to the abdominal tergite of segment XI (XIt) in length. Aedeagus T-shaped (Figs. 3 O–P) in both dorsal and ventral views, joined with basal part and apical winged plate; basal part of aedeagus short in lateral view, cylindrical, and membranous; apical winged plate somewhat hardened; transversely enlarged at caudal view, widest at middle and with a obviously concave gonopore (Fig. 3 N). Genital style triangular, basal part narrow and gradually widening to apex (Figs. 3 K–L). Measurements: Body length (from apex of vertex to tip of tegmen): 3, 7.9 ± 0.2 mm (n =17); Ƥ, 8.5 ± 0.1 mm (n =2); Body width: 3, 3.8 ± 0.3 mm (n =17); Ƥ, 3.9 ± 0.3 mm (n =2).

Shih (Canadian National Collection of Insects, Ottawa, Canada); 1 male, Nantou, Chushan, 24-IX-1999, H. T. Shih (National Museum of Natural Science, Taiwan, ROC.). Etymology: Named for the first author’s mother K. C. Kuan. Distribution: Taiwan. Host plants: Unknown. Remarks: This species can be distinguished easily from other Jembra species by the following characteristics: (1) antenna with 4 plate-shaped basiconic sensillae (Figs. 2 G–H) on the expanded flagellar base; (2) pronotum without obvious lateral carinae, median carina interrupted by some longitudinal wrinkles on the anterior margin (Fig. 3 A); (3) frons with median longitudinal carina (Fig. 3 B); (4) wing with 3 apical cells and without pubescence in apical cells (Fig. 3 E); (5) the first tarsus with apical spines arranged in 2 rows (Figs. 2 C, 3H); (6) the dorsal process of pygofer conical (Fig. 3 I); (7) genital style triangular (Figs. 3 K–L), without distinct slender inner and outer processes; (8) apical portion of aedeagus winged, and each lateral tip of winged portion directed ventrad (Figs. 3 O–P).
