Sphecodes pseudoredivivus Astafurova & Proshchalykin sp. nov. Figures 103, 104-109

Type material.

Holotype: ♀, Laos, Louang Prabang prov., 20°33'N, 102°14'E, Ban Songcha, 1200 m, 24.IV-16.V.1999 (OLBL/PCMS), Fig. 103.

Diagnosis.

This species is sculpturally closest to Sphecodes malayensis Blüthgen, 1927, S. redivivus Blüthgen, 1927 and S. sauteri Meyer, 1925 (refer to diagnosis of S. sauteri below) and possibly is the unknown female of S. redivivus owing to a similar sculpture of the hypoepimeral area.

Description.

Female (holotype, Fig. 103). Total body length 5.0 mm, fore wing 4.4 mm. Head (Fig. 104) black (except reddish antenna, yellow mouthparts and lower clypeus); transverse, ca. 1.2 times as wide as long; preoccipital carina absent; vertex weakly elevated, distance from top of head to upper margin of a lateral ocellus at most a half ocellar diameter as seen in frontal view and ca. 2 diameters as seen in dorsal view; mandibles simple; labrum short, semi-oval, 0.2 times as long as basalwidth; F1 transverse, 0.7 times as long as wide; F2 square; F3 1.2 times as long as wide; face densely punctate (15-20 μm / 0.5-1.5); ocello-ocular area (Fig. 105) and gena shiny, sparsely punctate (ca. 10 μm / 1-3); paraocular and supraclypeal areas with relatively dense plumose setae, but not obscuring integument; gena with sparse thin pubescence.

Mesosoma black with legs yellow-brownish to light yellow; wings hyaline, with weak yellowish darkening and light brown stigma and veins; stigma wide, 0.4 times as long as wide; hind wing with angle between basal (M) and cubital (Cu) veins ca. 90°, costal margin with five hamuli; mesoscutum and mesoscutellum (Fig. 106) finely punctate (10-20 μm / 1-4); metafemur elongate, weakly enlarged in the proximal half, maximum width 0.3 times its length; hypoepimeral area smooth with coarse and dense punctures (Fig. 108), mesepisternum areolate-punctate to rugose, but smooth with minute punctures along posterior margin. Propodeal triangle (metapostnotum) with a few coarse longitudinal wrinkles and shining smooth large interspaces (Fig. 107); lateral and vertical parts of propodeum roughly rugose with dense short plumose setae almost obscuring integument.

Metasomal T1 almost impunctate with a few minute setae pores (Fig. 109); remaining terga with sparse minute setae pores; marginal zones impunctate; T1-T2 red, remaining terga red-brownish; pygidial plate shining and very narrow, 0.4 times as wide as metabasitarsus. Sterna finely tessellate with dense shallow setae pores.

Male unknown.

Etymology.
