49. Cyrea gina Canepari and Gordon , new species

Description. Male holotype. Length 2.7 mm, width 2.0 mm; body elongate oval, convex. Dorsal surface with head, pronotum and elytron smooth, shiny. Color yellow except pronotum with black basomedian macula extended 3/4 distance to anterior pronotal margin, macula protruding medially, anterior border narrowly, deeply emarginate with yellow medially, anterolateral 1/4 of pronotum yellow; elytron black with 5 small, pale spots arranged in rows of 2 each with apical spot, humeral spot yellow, small, triangular, scutellar spot reddish yellow, irregularly rounded, apex slightly “ragged,” mediolateral spot reddish yellow, square, widely removed from lateral margin, discal spot reddish yellow, irregularly triangular, apical spot yellow, transversely oval with anterior border entire ( Fig. 271 ); ventral surface with head, prosternum, meso- and metaventrite black; abdomen yellowish brown, paler toward lateral margins. Head punctures small, separated by less than a diameter, each puncture slightly larger than an eye facet; pronotal punctures larger than head punctures, separated by less than to about a diameter, elytral punctures larger than on pronotum, separated by 1 to 3 times a diameter; metaventral punctures much larger than on elytron, separated by less than to about a diameter medially, larger and separated by less than a diameter in lateral 1/3. Clypeus emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 4 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin curved, basal margin without trace of bordering line medially. Epipleuron narrow, grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia with wide oblique angle, outer margin slightly arcuate, smooth, sponda slightly extended beyond angle ( Fig. 272 ). Carinae on prosternal process widely separated at apex, weakly convergent, joined at basal 1/3, connected to prosternal base by single carina. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite rounded throughout, extended forward at apex, ventrite with sparse, long pubescence and fine, dense punctures medially becoming denser laterally; ventrites 2-6 pubescent throughout, punctures fine, dense; 5th ventrite slightly depressed in median 1/3, apex shallowly emarginate; 6th ventrite medially depressed, apex weakly emarginate. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe 3/4 as long as paramere, asymmetrical, sides weakly convergent from base to rounded apex; paramere Pvl, lower margin produced in apical 1/2, lower margin curved upward to rounded apex ( Fig. 273, 274 ); sipho strongly curved in basal 1/2, without visible alae, basal capsule with inner arm long, wide, outer arm short and about as long as inner arm, with accessory piece, basal border broadly emarginate ( Fig. 275, 276 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Bolivia, Mapiri. ( ZMHB).

Geographical distribution. Bolivia.

Remarks. This species has male genitalia very similar to those of C. wilma , but differs from that species by the black elytral surface; spots on elytron small, pale, humeral and apical spots yellow, all other spots reddish yellow; mediolateral spot on elytron small, square, widely removed from lateral margin, not projected inward; prosternal carinae widely separated at apex; and head smooth, shiny, not alutaceous. In spite of similar male genitalia, these 2 species present strikingly differing appearances.
