Diagnosis
Methocha flavipalpus resembles Methocha nasiformis and Methocha strigosa based on the strong medial clypeal projection. It can be distinguished from those species by the coloration of the parategula, which has a transparent margin and the yellowish mandibles, palpi and legs; all black to dark or reddish brown in Methocha nasiformis and Methocha strigosa.
Description
Male.
Body length. 9–11 mm.
Head. Clypeus with acute to digitate medial projection (Fig. 11), apical margin emarginate; antennal lobes strongly convex; frons without medial projection or lobe above antennal sockets; frons punctures separated by 1 puncture diameter; vertex nearly impunctate; scapal ridge two-thirds length of scape; flagellomere I 1.7× as long as broad; flagellomere II 2.2× as long as broad; flagellomeres II and III 2.4× as long as broad; flagellomeres III–X arcuate; flagellomere XI 5× as long as broad.
Mesosoma. Pronotal disk gently convex medially, shoulders rounded, punctures large nearly contiguous; scutal punctures contiguous sublaterally becoming sparser medially; scutellum punctures 1–3 puncture diameters apart; mesopleuron with punctures separated by 1–2 puncture diameters apart; propodeum with coarse, contiguous, transversely striatiform punctures.
Metasoma. Terga polished, punctures separated by 1–2 puncture diameters; sterna I and VI with punctures separated by 1–2 puncture diameters; sterna II–V basally with punctures separated by 1 puncture diameter, separated from posterior part by smooth, transverse groove, posteriorly convex, with punctures separated by 2–4 puncture diameters.
Genitalia (Fig. 26). Paramere breadth at medial angle 3.0–3.3× breadth at halfway point between apex and medial angle, paramere length versus breadth at submedial angle is 4.6×.
Color. Black; mandibles and palpi whitish to yellow; fore and midcoxae may be pale brown, fore and mid legs brown with paler joints and tarsi; parategula bicolored, brown and whitish with transparent margin; wing membrane untinted, except posterior margin slightly brown-tinted in some specimens.
Vestiture. Sparse erect, silvery.
