28. Dilatitibialis connie Canepari and Gordon , new species

Description. Male holotype. Length 2.6 mm, width 2.2 mm; body rounded, slightly elongate, convex. Dorsal surface smooth, shiny except pronotum feebly alutaceous, shiny. Color dark brown except head yellow, pronotum with dark brown, basomedian macula extended almost 2/3 distance to anterior margin, apex of macula broadly, weakly emarginate with yellow; elytron with 5 small, yellow spots arranged in rows of 2 each plus apical spot, sutural spot triangularly elongate, apical spot transversely oval ( Fig. 152 ); ventral surface with mouthparts, prothoracic hypomeron, and legs yellow; abdomen with basal 3 ventrites dark brown medially, yellowish brown near lateral margin, remaining ventrites brownish yellow. Head punctures small, separated by a diameter or less, each puncture about as large as 2 eye facets; pronotal punctures larger than head punctures, separated by less than to twice a diameter; elytral punctures larger than those on pronotum, separated by 1 to 3 times a diameter; metaventral punctures larger than those on elytron, separated by a diameter medially, coarser, separated by less than a diameter toward lateral margin. Clypeus apically truncate or nearly so, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 5 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin rounded, basal margin without trace of bordering line. Epipleuron narrow, grooved, weakly descending externally, deeply emarginate for reception of femoral apices. Protibia widely flanged, flange wider than remainder of protibia, outer margin curved, smooth, sponda distinctly extended beyond protibial flange. Carinae on prosternal process narrowly separated at apex, convergent toward base, joined at basal 1/4 with single carina extended to basal margin of prosternum. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with primary pores laterally between ventrites 4-5 small, extended under apical 1/4 of 4th ventrite; postcoxal line on basal abdominal ventrite flattened along posterior ventrite margin, extended forward, ventrite with sparse, short pubescence and large, dense punctures medially; ventrites 2-4 pubescent throughout, punctures large medially, small, dense, becoming denser toward lateral margin; 5th ventrite coarsely, densely punctured in basal 1/3, apical 2/3 depressed, feebly depressed by primary pore laterally, without tubercle on each side of middle, apical margin broadly, weakly emarginate; 6th ventrite short, narrow, depressed medially, apical margin broadly emarginate, sparsely pubescent on each side of median depression, lateral angle abruptly rounded, surface feebly punctured. Apical tergite with apex weakly rounded. Genitalia with basal lobe short, wide, 2/3 as long as paramere, asymmetrical, sides parallel, apex rounded; paramere wide, curved, Psc, apex somewhat truncate, with small, ventral projection, trabes straight ( Fig. 153, 154 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm long, slender, nearly straight, apex rounded, outer arm about as long as inner arm, with accessory piece, basal border broadly emarginate ( Fig. 155, 156 ).

Female. Unknown.

Variation. Length 2.4 to 2.6 mm, width 2.0 to 2.2 mm. Dorsal background color varies from dark brown to black.

Type material. Holotype male; Peru, Tingo Maria , IX-10 44, EJ Hambleton. ( USNM) . Paratype; 1, same data as holotype ( USNM) .

Other specimens. 2. Brazil, Chapada, Brazil, Acc. No. 2966 ; horto flor ITCLS Paulo, 14.IX 1959, J. Halik, 13131, Halik Collection 1966. ( CMNH) ( USNM) .

Remarks. Dilatitibialis connie is distinguished from other species in this by an elytron with 5 yellow spots, sutural spot elongately triangular, apical spot transversely oval, and a Peruvian type locality. It bears a spot pattern similar to those of D. edna and D. florence , but has male genitalia with a more or less truncate parameral apex while the parameral apices of the other two species are rounded.
