Ischnopodabrasiliana Pa ś nik, sp. n. ( Figs. 53–55 )

Type material. Holotype: ♂: Brazil, S. Paulo, Estacao Atto da Serra vor., meridionalis , det. Bernhauer ( FMNH) . Paratype: ♀: Brazil, Catharina , Nova Teutonia, Plaumann, T. brasiliana Bernh., Cotyp. (manuscript name) ( FMNH) .

Description. Body. Length 2.9–3.1 mm, convex, parallel­sided, glossy; head pitch brown, pronotum red, elytra reddish brown, abdomen black with two basal tergites red, legs red, antennae brown with antennomeres 1–2 red.

Head circular in outline, convex, narrowly and shallowly impressed medially, widest across eyes; eyes large, moderately protruding from lateral contours of head, length of each seen from above subequal to that of postocular region; surface of head without microsculpture; puncturation fine and moderately dense; pubescence short and dense, directed inward. Antennae short, clearly increased in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4–6 longer than wide, antennomeres 7–10 quadrate, antennomere 11 nearly conical.

Pronotum slightly transverse, convex, widest in apical third, lateral sides rounded in front, gradually narrowed in straight line to obtuse hind angles; before base with moderately small and shallow transverse impression, moderately broadly and relatively shallowly impressed medially; surface without microsculpture; puncturation very fine, pinprick­like and dense; pubescence at midline directed entirely anteriorly.

Elytra subquadrate, wider than pronotum, at suture as long as pronotum at midline; surface without microsculpture; puncturation similar to that on pronotum.

Abdomen parallel­sided, bases of tergites 3–5 each with deep transverse impression, impressions coarsely and densely punctuate, tergal puncturation fine and moderately dense; pubescence short, dense and recumbent.

Male. Aedeagus as in Figs. 53–54 .

Female. Spermatheca as in Fig. 55 .

Remarks. Ischnopoda brasiliana resembles I. fissicollis , from which it differs by the pronotal surface impressed medially, the less transverse elytra; the more distinctly convex pronotum and by the shape of genitalia.

Distribution. The species is known only from two localities in Brazil.
