Libnotes (Libnotes) basistrigata ( Alexander, 1934) View in CoL
Limonia basistrigata Alexander, 1934: 40 View in CoL .
General body coloration yellow. Body length of male 10.715.0 mm, female 14.115.3 mm. Wing length of male 16.321.0 mm, female 17.519.0 mm.
Head brownish yellow, covered with sparse light gray pruinosity, which is denser along eye margin. Anterior vertex very narrow, covered with sparse erect light brown setae. Eyes large, ventrally nearly reaching each other. Length of male antennae 2.3 mm, if bent backwards, far not reaching base of wing. Antenna of female 2.65 mm long. Scape elongate, nearly cylindrical, brown, covered with sparse gray pruinosity. Pedicel very short, nearly rounded, light brownish yellow, bearing few erect setae. Flagellum 12segmented, yellow. Basal flagellomere very similar in shape and size to pedicel. Remaining flagellomeres getting oval to elongate towards apex, apical flagellomere wider at base, distal part suddenly narrow ed and blackened. It is approximately twice as long as preceding segment. Verticils approximately as long as respective segments on basal flagellomeres and approximately 1.5 times as long as respective segments on distal flagellomeres. Pubescence, covering segments short, yellowish, uniformly dense on all sides of flagellum. Rostrum brown, semipolished, covered only with very short pubescence. Palpus dark brown, covered with erect dark brown setae and silvery pubescence. Mouth parts brown at base, distal margin dark brown.
Thorax entirely yellow, unmarked. Wing ( Fig. 7D View Fig ) pale yellow, patterned with dark brown or black: distinct black spot at wing base in costal area before humeral vein; small brown spots surround base of Rs, Sc 2 and R 2, restricted brown areas surround cord, distal end of discal cell, basal and distal parts of vein Cu, middle part of R 4 + 5, distal end of A 2; dark spot also present at the very wing base, in axillary region. Costal field lighter than remaining wing area. Veins yellow, but brown in darkened areas. Venation: Sc long, Sc 1 reaching wing margin far beyond branching point of Rs, Sc 2 close to Sc 1 tip. Rs very short, slightly arched. Vein R 1 very short, transverse; R 2 transverse, slightly beyond the tip of R 1. Both branches of Rs very long, parallel to each other and distinctly arcuated towards posterior wing margin, thus cell r 1 very wide at wing margin. Crossvein rm distinct, at base of discal cell. Discal cell very long and narrow, approximately five times as long as wide. Longitudinal veins issuing from it arcuated towards posterior wing margin. Basal deflection of CuA 1 approximately its own length beyond branching point of M. A 1 long and nearly straight, A 2 shortened and strongly curved towards posterior wing margin, thus leaving very wide cell a 1 at wing margin. Anal angle small, but comparatively wide. Length of male halter 2.502.60 mm, that of female 2.352.55 mm. Stem of halter pale, base yellowish, knob blackish. Coxae and trochanters light yellow. Distal margin of trochanter rimmed with black. Femur yellow with dark brown distal end. Darkened part slightly widened. Whole segment covered with minute semierect brown setae. Tibia yellow with dark brown distal end. Basal half of first tarsomere brownish yellow, distal half dark brown, remaining tarsomeres dark brown. Male femur II: 13.3 mm, III: 14.616.2 mm; tibiae II: 14.1 mm, III: 15.8 mm; tarsus III: 7.7 mm long. Female femur I: 12.813.5 mm long, II: 12.5 mm, III: 15.3 mm; tibiae I: 15.5 mm, II: 15.3 mm, III: 13.5 mm; tarsus I: 14.1 mm, II: 15.4 mm long. Claw black, with few small subbasal teeth in both sexes.
Basal part of abdomen light yellow, distal segments obscure yellow. Male genitalia ( Fig. 7B View Fig ) yellow. Gonocoxite with elongate setose ventromesal lobe. Outer gonostylus long, narrow, rodshaped, strongly sclerotised. Inner gonostylus rounded, with long rostral prolongation armed with two long unequal spines arising from same tubercle and with additional lobe bearing four or five long powerful setae. Paramere with narrow distal part. Penis simple, elongate. Basal part of ovipositor ( Fig. 7G View Fig ) brownish yellow. Cercus and hypovalvae dark brown, semipolished. Cercus bifid at tip. Hypovalvae long and narrow, nearly reaching tip of cercus, distal end slightly enlarged.
Elevation range in Korea. Specimens from North Korea have no data at which altitudes they were collected. Single specimen from Jirisan National Park was found at nearly 380 m altitude.
Period of activity. Adults were collected only in the middle of October in North Korea.
General distribution. The species is known only from North Korea and Fujian province of China.
