24. Dilatitibialis gladys Canepari and Gordon , new species

Description. Male holotype. Length 2.4 mm, width 1.8 mm; body rounded, convex. Dorsal surface weakly alutaceous, shiny. Color yellow; pronotum with 6 small, brown spots, 1 triangular basomedian spot on each side of middle, 1 triangular spot on each side at middle of pronotum, and 1 irregular oval spot on each side near lateral margin; elytron with suture narrowly brown, 4 brown spots in rows of 2 each, humeral spot irregularly rounded, discal spot narrowly elongate, outer spot on apical declivity elongately triangular, inner spot on apical declivity elongate oval ( Fig. 129 ); ventral surface with head, prosternum, meso- and metaventrites dark brown; abdomen with median area of ventrites 1-3 dark brown medially, ventrites 1-3 laterally and ventrites 4-5 yellowish brown. Head punctures separated by less than to twice a diameter, each puncture as large as 1-2 eye facets; pronotal punctures larger than head punctures, separated by less than to about a diameter, elytral punctures larger than on pronotum, separated by 1 to 2 times a diameter; metaventral punctures larger than on elytron, separated by a diameter or less medially, becoming larger and separated by less than a diameter toward lateral margin. Clypeus feebly emarginate apically, lateral angle rounded, clypeus with sparse, long pubescence. Eye canthus elongate, about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle abruptly rounded, anterior angle abruptly rounded, lateral margin straight, basal margin without bordering line. Epipleuron narrow, grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia narrowly flanged, flange narrower than remainder of protibia, outer margin slightly arcuate, smooth, sponda slightly extended beyond flange. Carinae on prosternal process widely separated at apex, convergent toward base, acutely joined at basal 1/3 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 large, extended under apical 1/3 of 4th ventrite; postcoxal line on basal abdominal ventrite rounded throughout, extended forward, ventrite with sparse, long pubescence and dense punctures medially; ventrites 2-4 sparsely pubescent throughout, punctures large, dense, becoming denser toward lateral margin; 5th ventrite depressed in apical 1/2, apical margin broadly emarginate, surface densely punctate in basal 1/2, apical 1/ 2 nearly impunctate; 6th ventrite depressed medially, apical margin shallowly emarginate, angle on each side of median depression pronounced, abruptly rounded, surface impunctate. Apical tergite densely punctured, apex rounded. Genitalia with basal lobe 3/4 as long as paramere, asymmetrical, narrow, triangular from base to apex, apex rounded; paramere Psc, slender, weakly curved ( Fig. 130, 131 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm long, slender, apically truncate, outer arm slightly wider and longer than inner arm, with accessory piece, basal border widely emarginate ( Fig. 132, 133 ).

Female. Similar to male except clypeus and apex of frons brown, pronotal spots slightly larger than in male. Genitalia with spermathecal capsule short, wide in basal 1/2, abruptly narrowed in apical 1/2; bursal cap oval, with 3 arms, apical strut short, slender, slightly widened at apex ( Fig. 134 ).

Variation. Length 2.3 to 2.4 mm. Size and shape of dark pronotal and elytral spots slightly variable.

Type material. Holotype male; Brazil, San Antonio, No. 306, Montevideo So Amer Paras Lab , Date 5.23.43, Host, Berry. ( USNM) . Paratypes; 3, Brazil, Sao Paulo, Campos do Jordao , VII.1957, K. Lenko ( CMNH) .

Remarks. This is another species with a unique dorsal color pattern, although slightly reminiscent of D. poortmanni .

The holotype was collected in Brazil by a member (Berry) of a U.S. Department of Agriculture parasite laboratory then located in Montevideo, Uruguay.
