Methocha arcuata Kimsey 2011

Male. Body length. 7–11 mm. Head. Clypeus flattened medially (Fig. 9), apex truncate; antennal lobes rounded; frons without medial projection or lobe above antennal sockets; frons and vertex punctures separated by 1–2 puncture diameters; flagellomere I twice as long as broad; flagellomeres II and III 2.6–2.7× as long as broad; flagellomere XI 4× as long as broad. Mesosoma. Pronotal disk gently convex medially, shoulders evenly rounded; scutal punctures separated by 1 puncture diameter, except for less densely punctate medial area; scutellum nearly impunctate; mesopleuron highly polished with tiny sparse punctures, more than 4 puncture diameters apart; propodeum with dense, fine ridges, dorsally and ventrally arcuate (Fig. 25). Metasoma. Terga highly polished, punctures tiny and separated by 4 or more puncture diameters; sterna impunctate except for basal band of punctures 1 puncture diameter apart. Genitalia (Fig. 22). Paramere slender, with small medial angle, marked by transparent lobe, breadth at medial angle 2.0–2.3× breadth at halfway point between apex and medial angle, paramere length versus breadth at submedial angle is 6×. Color. Black, with pale yellow mandibles and fore and midcoxae, fore and mid legs may be yellowish brown; palpi whitish; wing membrane faintly brown-tinted apically. Vestiture. Sparse erect, silvery.
