51. Cyrea jessie Canepari and Gordon , new species

Description. Male holotype. Length 2.6 mm, width 2.0 mm; body elongate oval, convex. Dorsal surface with head, pronotum and elytron smooth, shiny. Color yellow except pronotum with faint, obscure, difficult to define pale brown maculae; elytron brown with 5 pale brown, mostly connected spots, humeral spot connected to apical spot along lateral margin of elytron, scutellar spot discrete but feebly separated from humeral and discal spots, discal spot narrowly connected to apical spot ( Fig. 283 ); ventral surface with head, prosternum, meso- and metaventrite yellowish brown; abdomen yellow. 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 a diameter, elytral punctures larger than on pronotum, separated by less than to twice a diameter; metaventral punctures slightly larger than on elytron, separated by a diameter or less 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 slightly curved, basal margin without trace of bordering line medially. Epipleuron wide, grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin slightly arcuate, smooth, sponda slightly extended beyond angle. Carinae on prosternal process widely separated at apex, convergent, joined at basal 2/5 of prosternum, 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 coarse, dense punctures; ventrites 2-3 with coarse, dense punctures medially, punctures finer laterally, ventrites 4-6 pubescent throughout, punctures fine, dense; 5th ventrite 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, slightly asymmetrical, slender, sides convergent from base to nearly acute apex; paramere Pvl, lower margin produced in apical 1/2, lower margin curved upward to rounded apex ( Fig. 284, 285 ); sipho strongly curved in basal 2/3, without visible alae, basal capsule with inner arm long, slender, apex feebly rounded, outer arm as wide as and longer than inner arm, with accessory piece, basal border widely, shallowly emarginate ( Fig. 286, 287 ).

Female. Similar to male except head with clypeus and apex of frons obscurely darkened. Genitalia with spermathecal capsule elongate, slightly curved medially, slightly wider in basal 1/4, cornu with abruptly rounded apex; bursal cap oval with 2 sclerotized arms, apical strut long, slender ( Fig. 288 ).

Variation. Paratype with pronotum and ventral surface reddish yellow.

Geographical distribution. Argentina, Paraguay.

Type material. Holotype male; ( Argentina) Argentine, J.M. Bosq, # F. C.C. 109. ( USNM) . Paratype; 1, Paraguay, Febrig , 24.III (remainder of handwritten label illegible) ( ZMHB) .

Remarks. The large, mostly connected elytral spots and primarily pale coloration of C. jessie are distinctive within this genus. The male genitalia have a paramere very similar to that of C. gina , but basal lobes differ as do the dorsal color patterns.
