Dolichomerus nigritus Bigot, 1859: 431.
Differential diagnosis.
A brown to black-brown species (Fig. 7 View Figures 7, 8 ) without distinct macula on wing but with darker medial area (Fig. 75 View Figures 74–76 ). It can be diferentiated from other Senaspis species with dark scutum and similar wing marking ( S. melanthysana , S. umbrifera ) by the contrasting yellow scutellum (Fig. 59 View Figures 56–59 ) (scutellum largely concolourous with scutum, at least along basal half in other species (Figs 58 View Figures 56–59 , 61 View Figures 60–63 ).

Description.
Body length: 14.2-18.2 mm. Wing length: 8.7-13.5 mm.
Male (Fig. 7 View Figures 7, 8 ). Head (Figs 36 View Figures 36–39 , 37 View Figures 36–39 ). Eye bare; holoptic, eye contiguity for distance equal to length of ocellar triangle, facets dorsally slightly larger, approx. three times as large in diameter as ventral ones. Frons black-brown; subshiny with brownish pollinosity; long pale yellow pile, especially dorsally and along eye margin. Face black-brown; subshiny with pale brownish to greyish pollinosity, in parts more densely so, ventral lateral margins largely devoid of pollinosity; in parts with dispersed long pale pile; facial tubercle strongly pronounced. Gena colour and pollinosity as ventral lateral margins of face; with short to long pale pile. Occiput black-brown, covered with grey pollinosity; with dispersed pale pile except dorsally where sometimes darker yellow. Antennal segments black-brown, basoflagellomere apically more brown, arista orange-brown.
Thorax (Fig. 59 View Figures 56–59 ). Scutum subshiny black, weak brownish pollinose; with short pale brown pile in anterior half, posterior part more black pile; postpronotum and notopleuron with longer mixed pale and dark pile. Scutellum apical margin weakly rounded, distinctly marginated, three times as wide as long; pale yellow to straw yellow, anterior margin narrowly black-brown; with short pale pile, along posterior margin somewhat longer. Pleura ground colour black-brown, covered with dispersed long pale or dark pile except on meron, dorsomedial anepimeron, ventral part of katepimeron, anterior part of katepisternum and anterior anepisternum.
Legs. Brown to black-brown, sometimes more rufous; with short black pile, along posterior margin of pro- and mesofemora with longer pale pile, along ventral margin of metafemur with longer dark pile. Metaleg (Fig. 87 View Figures 86–90 ), femur slightly thickened, with two distinct ventral swellings in apical third, swellings with dispersed short thick setae; tibia bent at base, thickened and slightly curved, pile along ventral margin in apical half to two-thirds longer and more dense.
Wing (Fig. 75 View Figures 74–76 ). Faint yellowish tinge, near cross-veins r-m and bm-cu more yellow-brown but no distinct medial macula; distal part of cells r2+3 and r4+5 more hyaline, as well as along posterior margin, paler areas not distinctly demarcated; alula largely hyaline. Calypters dull straw yellow with fringe of silvery white pile. Cell r1 closed, petiole very short, at most half height of base of stigma, rarely longer. Vein R4+5 sinuate, appendix absent or present.
Abdomen (Fig. 97 View Figures 97–101 ). Uniformly subshiny brown to black-brown, sometimes more rufous; with short dark pile except tergum I where more densely silver-grey pile; lateral margins intermixed with short pale pile, especially near postabdomen. Terga with dispersed long pale pile. Male genitalia as in Fig. 107 View Figures 102–113 .
Female. As male except for the following character states: Eye dichoptic (Figs 38 View Figures 36–39 , 39 View Figures 36–39 ), facets subequal in size. Frons and face pollinosity predominantly greyish; frons with short dark pile dorsally, greyish pile ventrally; with narrow pale fascia dorsally of antennal implant. Thorax dark pile sometimes more extensively so. Leg pilosity sometimes more brownish.
