description: Homalictus (H.) nabanensis sp.n.
(Figs 1 a–f, 2a–h, female; 3a–h, 4a–d, male)
Diagnosis. Homalictus nabanensis sp.n. belongs to Homalictus s. str. by its carinate propodeum. It is ended to H. behri (Cockerell, 1910) following the key of Walker (1986), but it can be distinguished from H. behri by the following combination of characters: Body with metallic greenish reflexions, propodeum, metasoma and legs black, tarsi yellowish brown in female, tarsi and tibias yellowish brown in males; female scutum superficially reticulate, not distinctly punctuate (Fig 2 b); dorsal surface of propodeum with strong rugae reaching rim of propodeum (Fig 2 c); disc of S2–S5 with brown hairs; and male genitalia with uniquely shaped penis valve.
Description. Female, flagellum 10–segmented, metasoma with five segments exposed, prepygidial fimbria separated by a longitudinal median specialized area of T5 (Fig 2 h). BL=5.0–5.5mm (holotype: 5.5mm) (Fig 1 a); first recurrent vein meets second submarginal crossvein, second recurrent vein enters third marginal cell (Fig 1 b); fore basitarsal comb fan shaped (Fig 1 d); hind basitibal plate complete and angulate apically (Fig 1 e); hind inner tibial spur with three teeth (Fig 1 f); outer undersurface of hind tibia concave (Fig 2 f); head broader than long, HW: HL = 47: 38, UOD: MOD: LOD: IOD: OOD = 22: 35: 25: 7: 7 (Fig 2 d); antenna geniculate; clypeus slightly convex, broader than long, width as nearly three times as its length, supraclypeal area obviously convex, antennal sockets separated by distance equal to diameter of socket (Fig 2 a), gena slightly narrower than eye, GW: EW = 9: 11; malar area absent; metasoma broader than that between tegulae, MtW: TW =56: 51. Frons and paraocular area with vertical striate, clypeus and supraclypeal area finely reticulate, no punctuate (Fig 2 a); scutum reticulate (Fig 2 b), without distinct punctuations; dorsal surface of propodeum sparsely reticulate, with strong rugae reaching rim of propodeum (Fig 2 c); metasomal terga no punctuate, shiny and transversely fine lineolate (Fig 2 d). Clypeus brassy with metallic reflection, supraclypeal area greenish blue with metallic reflection (Fig 2 a); scutum greenish blue intermixed with brassy metallic reflection (Fig 2 b); antennal flagellum ventrally dark blackish brown; distal 2/ 3 part of mandible reddish brown, basal 1/3 part black; tarsi yellowish brown, other parts of all legs black; frons, paraocular area, pronotum, scutellum, metanotum, propodeum and metasomal terga black. Clypeus, paraocular area, vertex, and scutum with yellowish white plumose hairs; gena, pronotal lobe and posterior surface of propodeum with white long plumose hairs; disc of T2–T3 with brown short simple hairs; ventrolateral parts of T1– T3 with numerous large yellowish brown plumose hair branches (Fig 2 e); plumose hair series of S2–S5 brown (Fig 2 g).
Male, flagellum 11-segmented, metasoma with seven segments exposed. BL=4.7–5.0mm (Fig 3 a); head broader than long, HW: HL = 44: 35, UOD: MOD: LOD: IOD: OOD = 25: 29: 20: 6: 6 (Fig 3 b); antenna geniculate; gena slightly narrower than eye, GW: EW = 8: 10; malar area absent; clypeus slightly convex, broader than long, width as nearly three times as its length, supraclypeal area convex, antennal sockets separated by distance equal to diameter of socket (Fig 3 b); metasoma slightly narrower than that between tegulae, MtW: TW =50: 55; wing venation of fore wing as same as that of female, first recurrent vein meets second submarginal crossvein, second recurrent vein enters third marginal cell (Fig 3 d); fore basitarsal comb fan shaped (Fig 3 e); hind basitibal plate complete and angulate apically (Fig 3 f); hind inner tibial spur with three teeth, hind tibia normal, without concave on outer undersurface (Fig 3 g). Frons and paraocular area with vertical striate, clypeus and supraclypeal area finely reticulate, no punctuate (Fig 3 b); scutum finely reticulate, sparsely punctate (Fig 3 h); dorsal surface of propodeum sparsely reticulate, median with a few longitudinal strong rugae reaching rim of propodeum (Fig 4 a); metasomal terga no punctuate, shiny and transversely fine lineolate (Fig 4 b); gonobase slightly narrower than gonocoxite (Fig 4 c), penis valve long, tapering sharp apically and bending ventrally (Fig 4 d). Clypeus, supraclypeal area, and scutum greenish blue; pronotum, scutellum, metanotum, propodeum and metasomal terga black; antennal flagellum ventrally dark blackish brown; apical 1/3 part of mandible reddish black, middle part yellowish brown, basal part black; tibiae and tarsi yellowish brown, other parts of all legs black. Clypeus covered with denser yellowish white plumose hairs; gena and scutum with sparse white plumose hairs; disc of S2–S5 with sparse yellowish brown branched hairs.
