24. Cyrea maureen Canepari and Gordon , new species

Description. Male holotype. Length 2.3 mm, width 1.8 mm; body somewhat rounded, oval, convex. Dorsal surface with head slightly alutaceous, weakly shiny, pronotum and elytron smooth, shiny. Color yellow except pronotum with short, narrow, dark brown basomedian macula extended slightly more than 1/2 distance to anterior pronotal margin, macula with wide, oblique projection on each side of middle, projections widely separated; elytron dark brown with 6 yellow spots arranged in rows of 2 each with apical spot plus intermediate spot at middle posterior to humeral and scutellar spots, humeral spot rectangular, scutellar spot widely triangular, mediolateral spot irregularly oval, discal spot oval, apical spot transversely rectangular, anterior border of spot entire, intermediate spot small, oval ( Fig. 128 ); ventral surface with head, prosternum, meso- and metaventrite dark brown; abdomen yellowish brown. Head punctures small, separated by less than a diameter, 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 on pronotum, separated by less than to twice a diameter; metaventral punctures larger than on elytron, separated by less than to twice a diameter medially, larger and separated by less than a diameter in lateral 1/3. Clypeus weakly 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 narrow, bisinuate flange, outer margin sinuate, smooth, sponda slightly extended beyond angle ( Fig. 129 ). Carinae on prosternal process narrowly separated apically, convergent, joined at basal 1/6 of prosternum, connected to base with single carina. Metaventrite without setal tuft. Basal abdominal ventrite with setal tuft. Abdomen with postcoxal line on basal abdominal ventrite rounded throughout, extended forward at apex, ventrites 1-2 with dense, short pubescence and fine, dense punctures; ventrites 3-6 with long, dense pubescence throughout, punctures fine, dense; 5th ventrite depressed in median 1/3, apex widely, shallowly emarginate; 6th ventrite medially depressed, apex deeply, abruptly emarginate. Apical tergite finely, densely punctured, apex emarginate, lateral angle widely, strongly projected. Genitalia with basal lobe nearly as long as paramere, asymmetrical, sides convergent to narrowly rounded apex; paramere Pav, sinuate, apically truncate, widened from base to apex, upper margin broadly emarginate medially, with large, almost membranous projection terminating in small, apically acute, sclerotized “ear” ( Fig. 130, 131 ); sipho strongly curved in basal 1/2, without visible alae, basal capsule with inner arm long, slender, apex slightly rounded, outer arm slender, curved, slightly longer and wider than inner arm, with accessory piece ( Fig. 132, 133 ), basal border sinuate.

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Surinam, Paramaribo, 20-vii-1980, M.I. Russell, general sweeping. ( BMNH).

Geographical distribution Surinam.

Remarks. This species differs from most other Cyrea taxa by having 6 spots on each elytron, the 6th spot medially in anterior 1/2 posterior to humeral and scutellar spots. It shares with C. colleen protibiae with bisinuate flange, apex of male 6th abdominal ventrite abruptly, deeply emarginate, and apical tergite with wide, large projection on lateral angle.

Cyrea maureen and C. colleen share similar protibial flanges, but have nothing else in common. The sinuate paramere of the male genitalia of C. maureen is slightly similar to that of C. agnes , but that species does not have an apical “ear.”
