Description. Male. Length 3.6 mm, width 2.8 mm; body rounded, convex. Dorsal surface shiny, lacking alutaceous sculpture except head alutaceous, dull. Color yellow except pronotum with 7 brown spots, 1 small, round spot on each side in lateral 1/4, 1 small, round, basomedian spot anterior to scutellum, 1 triangular basal spot on each side of middle anterior to scutellum, 1 triangular spot medially on each side of middle; elytron with 9 small brown spots, basal row with 2 spots, discal and apical declivity with rows of 3 spots each, 1 apical spot ( Fig. 39 ); ventral surface with prosternum, meso- and metaventrites black; abdomen mostly dark brown except ventrites 5-6 brownish yellow. Head punctures small, separated by a diameter or less, as large as or slightly larger than an eye facet; pronotal punctures slightly larger than head punctures, separated by a diameter or less; elytral punctures as large as on pronotum, separated by 1 to 2 times a diameter; metaventral punctures larger than on pronotum, separated by a diameter or less medially, becoming larger and separated by less than a diameter toward lateral margin. Clypeus apically emarginate, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 5 eye facets long, straight, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin feebly curved, basal margin without bordering line. Epipleuron narrow, grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia narrowly flanged, flange as wide as remainder of protibia, outer margin rounded, smooth, sponda slightly extended beyond protibial flange. Carinae on prosternal process widely separated at apex, convergent to basal 1/4, joined at basal 1/4 with single carina extended to basal margin of prosternum. Metaventrite with dense, long setal tuft. Basal abdominal ventrite with dense, long setal tuft. Abdomen with primary pores laterally between ventrites 4-5 small, extended under apical 1/4 of ventrite 4; postcoxal line on basal abdominal ventrite rounded, extended to apical margin of ventrite at middle, flattened along margin, then broadly forward, ventrite with sparse, long pubescence and dense, sparse punctures medially; ventrites 2-4 sparsely pubescent throughout, punctures small, dense; 5th ventrite depressed medially at apex, dense patch of long pubescence on each side of median depression, without tubercle on each side of middle, apical margin broadly emarginate, surface nearly impunctate; 6th ventrite short, narrow, depressed medially, apical margin broadly emarginate, sparsely pubescent on each side of median depression, surface nearly impunctate. Apical tergite densely punctured, pubescent, apical border rounded. Genitalia with basal lobe shorter than paramere, asymmetrical, slightly narrowed from base to oblique apex; paramere Unm, straight, ventrally narrowed before apex ( Fig. 40, 41 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm short, narrow, apically obliquely truncate, outer arm wider than inner arm, slightly longer than inner arm, with large accessory piece, basal border widely emarginate ( Fig. 42, 43 ).

Female. Similar to male except head with small, triangular brown spot widest on clypeus, narrowed to median portion of frons. Genitalia with spermathecal capsule short, wide, narrowed at middle; bursal cap rounded, with 2 distinct outer arms, apical strut long, strongly spatulate at apex in lateral view ( Fig. 44 ).

Variation. Length 2.6 to 3.9 mm, width 2.3 to 2.9 mm. Dorsal brown spots vary from pale brown to nearly black; pronotal spots may be partially connected, forming a mediobasal loop with small, elongate yellow spot in middle; brown spot on female head varies from that described above to very small, present only on anterior 1/2 of frons.

Type locality. Brazil.

Type depository. ZMHB (lectotype here designated).

Geographical distribution. Brazil.

Specimens examined. 58. Brazil. Distributed throughout much of eastern Brazil. ( BMNH) ( CMNH) ( MZSP) ( USNM) ( ZMHB).

Remarks. Dilatitibialis glyphica is recognized by the distinctive dorsal color pattern, although it has a superficial resemblance to D. hybridula . In addition to superficial color differences, D. glyphica is distinguished from D. hybridula by slightly smaller size and males with dense, long setal tufts on both metaventrite and basal abdominal ventrite.

The lectotype is a male labeled “ZMHUB - “55688/ glyphica Muls. Bras (handwritten)/ Zool. Mus. Berlin (yellow paper)/ Hist. Coll. ( Coleoptera ), Nr. 55688, Psyllobora glyphica Muls. , Brasil, Zool. Mus. Berlin (dark green paper).” Mulsant (1850) had specimens from the Dupont, Germar and Schaum, and Paris Museum collections.

Milléo et al. (1997) correctly transferred this species from Hyperaspidini to Brachiacanthini , placing it in Cyra . Because it has obvious primary abdominal pores, we transfer C. glyphica to Dilatitibialis .
