Diagnosis
The most distinctive features of Methocha depressa are the coarsely areolate propodeum, the shape of the frontal projection above and between the antennal lobes and the sublaterally impressed pronotal disk. This species does not closely resemble any of the other Malagasy Methocha species, although the depressed pronotum resembles that of Methocha robusta, which differs in having the pronotal depression interrupted medially.
Description
Male.
Body length. 5–7 mm.
Head. Clypeus with obtuse medial projection (Fig. 10), apex linear or shallowly emarginate; antennal lobes rounded; frons with strong medial projection or lobe above antennal sockets (Fig. 18); frons and vertex punctures separated by 1–2 puncture diameters; scapal carina less than half length of scape; flagellomere I 1.7× as long as broad; flagellomere II 2.5× as long as broad; flagellomere III 2.8× as long as broad; flagellomeres IV–X arcuate; flagellomere XI 5× as long as broad.
Mesosoma. Pronotal disk strongly depressed on either side of elevated midline posterior to anterior margin, shoulders evenly rounded (Fig. 18); scutal punctures separated by 1 puncture diameter, except for less densely punctate medial area; scutellum nearly impunctate; mesopleural punctures 1–2 puncture diameters apart; propodeum with coarse, contiguous areolae (Fig. 24).
Metasoma. Terga highly polished, punctures tiny and separated by 4 or more puncture diameters; sternum I punctures 1 puncture diameter apart; sterna II-V anteriorly with contiguous punctures, separated from posterior part by punctulate transverse groove, posteriorly strongly convex, punctures 1–2 puncture diameters apart.
Genitalia (Fig. 23). Paramere breadth at medial angle 1.5× breadth at halfway point between apex and medial angle, paramere length versus breadth at submedial angle is 6×.
Color. black; clypeus sometimes partly reddish brown; mandibles reddish; palpi yellow to pale brown; parategula black; legs dark brown to black; palpi whitish; wing membrane untinted apically.
Vestiture. Sparse erect, silvery.
