Pseudisobrachium magnum sp. nov. ( Figs. 61–64 View FIGURES 52 – 64. 52 – 57 )

Description.— Male. Body length 4.76 mm; LFW 3.20 mm. Color: head, mesosoma and metasoma black; mandible and antenna black; legs black; wings subhyaline, veins light castaneous. Pubescence conspicuous.

Head ( Fig. 61 View FIGURES 52 – 64. 52 – 57 ): mandible with 5 teeth ( Fig. 62 View FIGURES 52 – 64. 52 – 57 ). Clypeus with trapezoidal median lobe, with a median polished spot. First four antennal segments in a ratio of 40: 7: 21: 20; segment III 2.0 X longer than thick, segment XI 2.75 X; flagellar pubescence subappressed, with some erect setae. Frons strongly coriaceous, with small, conspicuous and abundant punctures, WH 0.95 X LH, WF 0.71 X WH, WF 1.48 X HE; DAO 0.12 X WF; OOL 1.15 X WOT, frontal angle of ocellar triangle acute; VOL about 0.87 X HE. Vertex broadly convex. Temples slightly divergent anteriorly.

Mesosoma: pronotum and mesonotum coriaceous, punctured as on frons, pronotal disc short, concave in profile, with a posterior transverse furrow; notauli shallow, present only apically; parapsidal furrows almost complete; scutellar disc coriaceous. Propodeal disc 1.02 X as long as wide, 1.86 X as long as high, basal triangle striate, posterior portion of disc and declivity finely strigulate, median carina incomplete, the posterior absent, lateral portion of propodeum weakly aciculate. Mesopleuron strongly punctured, with a large and polished callus. Fore wing with discoidal vein spectral, weakly pigmented, interstitial with median vein.

Genitalia ( Fig. 63–64 View FIGURES 52 – 64. 52 – 57 ): paramere with ventral arm approximately 2.5 X wider than dorsal arm, the ventral concave; vannus with 5 grooves; aedeagus elliptical, apex emarginate, wide before the apex.

Material examined.— HOLOTYPE: male, BRAZIL, Espírito Santo, Santa Teresa, Estação Biológica de Santa Lúcia, 30.I. 2001, sweeping, C.O. Azevedo & R. Kawada col. ( UFES). PARATYPES: BRAZIL, Espírito Santo, 0 2 males, Santa Teresa, Estação Biológica de Santa Lúcia, 23.II– 28.III. 2001, sweeping, C.O. Azevedo & R. Kawada col. ( UFES); 0 1 male, Cariacica, Reserva Biológica de Duas Bocas, 26.XII. 1996, sweeping, C.O. Azevedo & H. S. Sá col. ( UFES).

Discussion.— This species is similar to P. cuspidatum , but here the apical margin of clypeus is concave and the ventral arm of paramere is narrower.

Etymology.— The specific epithet refers to the genitalia size.

Distribution.— Brazil (Espírito Santo).
