DISTRIBUTION: NC Vietnam: Ha Tinh (Huong Son). BIOLOGY: Unknown. DIAGNOSIS: Antenna with 38 segments, with antennal segments 11–20 cream white; maxillary palp 1.6 <b>×</b> as long as head; frontal protuberance long, acute and raised higher than lateral carinae of frons; in dorsal view width of head 1.6 <b>×</b> its median length; height of eye 1.55 <b>×</b> temple. Length of mesosoma 1.9 <b>×</b> as long as high; notauli wide and shallow, largely rugose, fused posteriorly with longitudinal rugosities; scutellum rather short, rugose; propodeum coarsely rugose. Foretarsus 1.2 <b>×</b> longer than foretibia; forewing 3.1 <b>×</b> longer than its maximum width; vein 3-SR short, 0.6 <i>×</i> vein r; second submarginal cell trapezium-shaped, vein 2-M 3.7 <b>×</b> 3-SR; vein 1-M of hind wing 0.55 <i>×</i> vein 1r-m; vein 2-SC+R transverse; hind wing with 4 hamuli. Hind femur robust, with a rather wide obtuse protuberance, without distinct ventral serrations; length of hind femur (without protuberance) 3.1 <i>×</i> its maximum width; outer side of hind coxa sparsely finely punctate; hind femur densely punctate laterally. First tergite 1.1 <b>×</b> longer than its apical width; dorsal carinae in basal 0.7 of tergite; median length of second tergite 0.6 <b>×</b> as long as its basal width, and 1.15 <b>×</b> third tergite; first tergite largely smooth basally, transversely rugose mediolaterally and nearly areolate-rugulose medioapically; second tergite punctate-reticulate, but smooth medially and remainder shiny and smooth. NOTES: <i>W. aspera,</i> sp. nov., runs in the key by Yan et al. (2017) to <i>W. zhejiangensis</i> Yan and van Achterberg, 2017, from China and can be separated as follows: (1) frontal protuberance near antennal sockets evenly narrowed from base to apex, roundly pointed apically (frontal protuberance with posterior protruding narrow lamella in <i>W. zhejiangensis</i>); (2) forewing vein r 1.7 <b>×</b> vein 3-SR (1.1 <b>×</b> in <i>W. zhejiangensis</i>); and (3) hind wing vein 1-M 0.55 <b>×</b> vein 1r-m (0.4 <b>×</b> in <i>W. zhejiangensis</i>). The new species is also similar to <i>W. albobasalis</i> van Achterberg and Chen, 2017, from China, but differs from the latter by having: (1) hind femur slender, length 3.1 <b>×</b> its maximum width (2.8 <b>×</b> in <i>W. albobasalis</i>); (2) vein r of forewing 1.7 <b>×</b> vein 3-SR (1.1 <b>×</b> in <i>W. albobasalis</i>); (3) vein 1-M of hind wing 0.55 <b>×</b> vein 1r-m (0.4 <b>×</b> in <i>W. albobasalis</i>); and (4) occiput smooth (sparsely punctate in <i>W. albobasalis</i>), 11th–20th antennal segments 11–20 cream white (3–11 in <i>W. albobasalis</i>).

ETYMOLOGY: From <i>asper</i> (Latin for “rough,” “harsh”), because the flat medioposterior area of mesoscutum is coarsely rugose.
