Lathrolestes sexmaculatus Reshchikov & Lee sp.n. – Wikispecies link – ZooBank link – Pensoft Profile
Diagnosis
This species is similar to Lathrolestes grahami Reshchikov, 2012 and Lathrolestes tolstoyi Reshchikov, 2012 but distinguishable by combination of the following characters: claws not pectinate, malar space 0.9 × as long as basal mandible width; face in female black with small yellow macula between antennal socket and eye margin, ventral part of eye, lateral edge of clypeus, face in male mostly yellow with black bands ventral part of antennal sockets, malar space and middle apical part of clypeus.
Description
Female. Body length 7.3 mm.
Head. Matt, distinctly punctate with fine and dense punctures on shagreen surface (Fig. 2C). Face 1.3 × as broad as eye height, relatively flat, bulging (Fig. 2B). Clypeus distinctly separated from face by groove, at apex projecting anteriorly (Fig. 2B); apical margin of clypeus thick. Clypeal fovea relatively small. Malar space 0.9 × as long as basal mandible width. Lower mandible tooth almost equal to upper. Occipital carina complete.
Mesosoma. Matt. Pronotum distinctly punctate. Epomia absent. Mesoscutum distinctly punctate, matt, with notaulus shallow. (Fig. 2E). Mesopleuron finely and densely punctate, polished (Fig. 2D). Claws not pectinate. Fore wing with R intercepting pterostigma before its middle (Fig. 2J); areolet petiolate; vein 2m-cu of fore wing with single bulla. Vein cu-a of hind wing interstitial, with cu-a intercepted by Cu1 below middle. Propodeal carinae complete (Fig. 2H).
Metasoma. Matt, distinctly and densely punctate (Fig. 2K). Tergite 1 1.2 × as long as broad apically, convex, with longitudinal dorsal carinae distinct basally and medial impression (Fig. 2I). Tergite 2 transverse, trapezoidal (Fig. 2K). Following tergites also transverse. Ovipositor straight, stout, with rather shallow notch in the middle (Fig. 2L).
Color. Body mostly black (Figs 2A–K). Mandible except teeth, lateral edges of clypeus, maculae ventral eye and between eye and antennal sockets, fore tibia and tarsus except apical tarsal segment, basal half of middle tibia, and basal part of hind tibia yellowish (Fig. 2A)
Male. Body length 7 mm. Character states are mostly the same as in female. Parameres elongate (Fig. 2F).
Color. Same as in female but scape and face mostly yellow (with band ventral part of each scape, tip of clypeus and malar space black) (Fig. 2G).
Etymology
Name sexmaculatus refers to six yellow maculae on head in female.
