1. Cyrea mattie Canepari and Gordon , new species

Description. Male holotype. Length 3.0 mm, width 2.3 mm; body oval, convex. Dorsal surface slightly alutaceous, shiny. Color yellow except pronotum with narrow, pale brown basomedian macula extended about 1/6 distance to anterior pronotal margin, medially with faint trace of small, triangular macula on each side of middle; elytron with narrow brown border on sutural margin, laterally with dark brown macula narrow at humeral callus, obliquely extended posteriorly to apical declivity, then curved toward suture, connected to suture on apical declivity ( Fig.1 ); ventral surface including abdomen entirely yellow. Head punctures small, separated by a diameter or less, each puncture about as large as an eye facet; pronotal punctures larger than head punctures, separated by a diameter or less, elytral punctures larger than on pronotum, separated by less than to about a diameter; metaventral punctures larger than on elytron. Clypeus emarginate apically, 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 weakly rounded, basal margin with trace of bordering line medially. Epipleuron narrow, not grooved, descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin slightly curved, smooth, sponda slightly extended beyond protibia. Carinae on prosternal process widely separated at apex, convergent toward base, joined at basal 1/3, single carina extended to prosternal base. Metaventrite with setal tuft. Basal abdominal ventrite with setal tuft. Abdomen with postcoxal line on basal abdominal ventrite slightly flattened along posterior ventrite margin, extended forward at apex, ventrite with small, dense punctures; ventrites 2-6 pubescent throughout, punctures fine, dense; 5th ventrite not depressed medially, apical margin broadly, feebly emarginate, angle on each side of emargination with tuft of setae; 6th ventrite short, narrow, depressed medially, apical margin weakly emarginate, angle on each side of emargination abrupt. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe 3/4 as long as paramere, asymmetrical, sides convergent from base to rounded apex; paramere Unm, widened from base to obliquely rounded apex ( Fig. 2, 3 ); sipho strongly curved in basal 2/3, without visible alae, basal capsule with inner arm elongate, narrow, apex obliquely truncate, outer arm slightly wider and longer than inner arm, with small accessory piece, basal border widely, shallowly emarginate ( Fig. 4, 5 ).

Female. Similar to male except head pale brownish yellow, pronotum with median 1/2 pale brownish yellow, lateral 1/4 yellow. Genitalia with spermathecal capsule short, wide, weakly curved, widened from base to apex; bursal cap oval, with 2 sclerotized arms, apical strut long, slender, sinuate ( Fig. 6 ).

Variation. Length 2.6 to 3.3 mm, width 2.0 to 2.5 mm. Elytron with brown sutural border pale brown to darker brown, often widened in basal 1/2, curved macula may be broken posterior to humeral callus, forming small anterior spot and long posterior macula, or it may be reduced to small, pale brown spot on humeral callus and large, dark brown spot on apical declivity.

Remarks. Cyrea mattie has a distinctive, although somewhat variable, dorsal color pattern by which it may be usually recognized. It has male genital parameres of the type found in Serratitibia , and also has males with long setal tufts on both metaventrite and basal abdominal ventrite, both characters will aid in distinguishing this species.
