50. Cyrea maxine Canepari and Gordon , new species

Description. Male holotype. Length 2.6 mm, width 2.0 mm; body elongate oval, convex. Dorsal surface with head alutaceous, weakly shiny, pronotum and elytron smooth, shiny. Color yellow except pronotum with narrow, wide, dark brown basomedian macula extended almost 1/3 distance to anterior pronotal margin, small, curved brown spot present on each side of middle anterior to basomedian spot; elytron brown with 5 large yellow spots arranged in rows of 2 each with apical spot, humeral spot elongately triangular, feebly connected to mediolateral spot, scutellar spot rounded, mediolateral spot strongly projected inward, discal spot oval, apical spot transversely oval with anterior border entire ( Fig. 277 ); ventral surface with head, prosternum brown, meso- and metaventrite black; abdomen with median 2/3 of ventrites 1-3 dark brown, lateral 1/3 of ventrites 1-3 and ventrites 3-6 reddish brown. Head punctures small, separated by less than a diameter, each puncture as large as an eye facet; pronotal punctures larger than head punctures, separated by less than to twice diameter, elytral punctures larger than on pronotum, separated by less than to twice a diameter; metaventral punctures much 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, descending externally, deeply emarginate for reception of femoral apices. Protibia with wide oblique angle, outer margin slightly arcuate, smooth, sponda slightly extended beyond angle. Carinae on prosternal process widely separated at apex, abruptly convergent, joined at prosternal base. 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 medially becoming denser laterally; ventrites 2-6 pubescent throughout, punctures fine, sparse medially, becoming denser laterally; 5th ventrite depressed in median 1/3, apex shallowly emarginate; 6th ventrite medially depressed, apex emarginate. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe 3/4 as long as paramere, asymmetrical, sides convergent from base to obliquely truncate apex; paramere Pvl, slender, lower margin weakly produced medially in apical 1/2, lower margin curved upward to rounded apex ( Fig. 278, 279 ); sipho strongly curved in basal 1/2, without visible alae, basal capsule with inner arm short, narrow, apex truncate, outer arm wider and longer than inner arm, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 280, 281 ).

Female. Similar to male except head yellowish red with faint, dark brown border along eye, pronotum with basomedian macula extended nearly to anterior pronotal margin. Genitalia with spermathecal capsule elongate, slightly curved medially, slightly wider in basal 1/4, cornu with rounded apex; bursal cap oval with 3 sclerotized arms, apical strut long, slender except apical 1/8 weakly spatulate ( Fig. 282 ).

Variation. Length 2.4 to 2.6 mm, width 1.9 to 2.0 mm. Pronotal macula subject to minor change in size and shape.

Type material. Holotype male; Brazil, Faz. Pau d’Alho Itú, 27-XII-959, Col: U. Martins. ( MZSP) . Paratypes; 2, 1, ( Brazil) Vila Monte Verde , Minas Gerais., 10.ZII 1969, J. Halik 9280 ( MZSP) ; 1, V. Monte Verde , Minas Gerais., 19.XI.1966, J. Halik 5364 ( MZSP) .

Geographical distribution. Brazil.

Remarks. Cyrea maxine has the male paramere slender, with ventral projection limited to the apical 1/2. Within this group it has the least modified paramere. It is distinguished from other group members by the patterned male pronotum; reddish female head; and elytron with humeral and mediolateral spots weakly connected along the lateral border.
