Calomutilla crucigera ( Burmeister, 1854)

( Figs 6–9 , 31–35 , 46–53 )

Description. MALE (hitherto undescribed). Body length 4.0 mm. Color: integument dark reddish brown, with head, mesoscutum, scutellum and propodeum darker, and pronotum, T1, apical terga and all sterna slightly paler; antennal tubercle translucent above yellowish radicle of scape, clypeus and appendages reddish brown, mandible yellow with dark apex, tegula translucent yellowish brown; tibial spurs pale whitish; wings very weakly infuscated, veins pale yellowish brown; head mostly with long white setae, except inner margin of eye with very few long dark brown erect setae; mesosoma and metasoma with long erect white setae except mesoscutum and scutellum with dark setae, metapleuron and side of propodeum with short recumbent white setae; legs with white setae.

Head. Transverse in dorsal view, broadly trapezoidal, sides behind eyes converging posterad and broadly round- ed into weakly convex posterior margin, 1.77 × as wide as long; frons, vertex and gena with small, fairly dense punctures, and a distinct smooth area postero-lateral to ocelli; eye 0.56 × as long as minimal distance between them; ocelli very small, interocellar distance 2.43 × diameter of lateral ocellus, distance between eye margin and lateral ocellus 5.71 × as long as diameter of ocellus and 2.35 × interocellar distance; genal carina absent; clypeus convex medially, its antero-medial margin slightly concave and with a small sharp obtuse tooth in front of each antennal tubercle; oral fossa not extending to base of mandible; hypostoma without spines; mandible apex tridentate, inner margin with a small obtuse tooth intermediate between insertion of mandible and dorsal tooth of apical three, ventral margin smooth, without a process or tooth; scrobal carina reduced to an inconspicuous tubercle between antennal tubercle and eye; antennal tubercle simple, without protuberance or carina; scape with a single longitudinal carina below; first flagellomere 1.19 × as long as second.

Mesosoma. Pronotum, mesoscutum, scutellum and mesopleuron with small, fairly dense punctures; tegula evenly convex, smooth and shining; scutellum slightly convex; disk and declivity of propodeum evenly merging, broadly and strongly reticulate; pronotum with humeral area rounded except for small tuberculate epaulet; metapleuron and propodeum laterally smooth and shining; fore wing with two closed submarginal and one closed discal cells, veins 3rs-m and 2m-cu faintly spectral, marginal cell with rectangular apex.

Metasoma. T1 conical, broadened apically with contour merging with T 2 in dorsal view, 0.65 × as long as wide, 0.43 × length and 0.55 × width of T2; T1 with few small punctures; T2 with lateral felt line narrow and well defined, 0.43 × as long as lateral margin; T2 mostly shining with small very sparse punctures, except posterior fifth with smaller, dense punctures similar to those on T3–T6; T7 with small dense punctures sparser medially, apical margin briefly recurved and almost straight medially; S1 with weak median, longitudinal carina tapering posteriorly; S2 without felt line; S2 mostly with small sparse punctures; S3–S6 with small, close punctures sparser medially; S7 very short, smooth; hypopygium simple and flattened, with small dense punctures, apex weakly convex.

Genitalia. Paramere in dorsal view narrow and strongly sinuate, in lateral view broad basally, weakly curved ventrad and evenly narrowed to simple and scarcely recurved apex, with dense long setae on most of ventral margin but becoming sparser apicad, few shorter setae mesad on apical fifth; parapenial lobe apically narrow and strongly incurved; gonobase in ventral view with strong medio-apical acute tooth projecting into concavity of penis valve; volsella with cuspis and digitus short, cuspis broad with long setae ventrally and medium-size setae apically, digitus narrow without setae, shorter than apex of cuspis; penis valve with dorsal margin of body almost straight, uneven and very weakly concave anteriorly, very small apico-ventral tooth and no preapical tooth, apex with laterally recurved margin forming a concavity but without any lateral lamellate flange.

Material examined. BRAZIL: MARANHÃO, Vitória do Mearim , ~ 150 km SW São Luís, 26.ix.1992, R. Cam- bra, D. Quintero, 1♂, 6♀ (1♂, 1♀ DJBC, 5♀ MIUP) . (det. as Calomutilla crucigera by Quintero 1992).

Comments. The identification of this specimen as being the male of C. crucigera is based on the capture of the male and females at the same place and time (see material examined). No other species of Calomutilla was collected at this locality. Therefore, we feel justified in describing the male as the opposite sex of C. crucigera instead of as a new species.
