Type material
Holotype male: “BRASIL: Mato Grosso: Mpio. Cotriguaçu, Fazenda São Nicolau, Prainha, 9°51.6'S, 58°12.9'W, flight intercept, Oct. 2009, F.Z.Vaz-de-Mello” / “Caterino/Tishechkin Exosternini Voucher EXO-01301” (CEMT).
Diagnostic description
Length: 2.0 mm, width: 1.8 mm; as for generic description, plus the following specific characters: body rufescent, with ground punctation very fine and sparse; right mandible with small, acute basal incisor tooth; apical marginal elytral stria absent, apical sutural striole strongly reduced; basal propygidial stria interrupted for about one-fifth width of propygidium; ground punctation of propygidium slightly more conspicuous than that of pygidium; pygidium about one-third longer than basal width, with lateral marginal striae in basal half, apex bluntly subacute; prosternal keel lacking carinal striae; prosternal lobe with marginal stria well impressed in middle; postmesocoxal stria recurved around coxa to mesepimeron; secondary punctures of sides of metaventrite small and uniform but rather dense; lateral stria absent from metepisternal margin; metepisternum with complete longitudinal stria; 1st abdominal ventrite with lateral stria difficult to distinguish from ground strigosity.
Remarks
This species’ most distinctive character is its very distinctly prolonged pygidial apex (Fig. 16D). It also, like the preceding species, has its postmesocoxal stria recurved completely to the mesepisternum, but has its basal propygidial stria interrupted medially.
Etymology
This species’ name refers to the acuminate pygidium.
