31. Cyrea natalia Canepari and Gordon , new species

Description. Male holotype. Length 2.5 mm, width 2.1 mm; body rounded, somewhat elongate, convex. Dorsal surface with head slightly alutaceous, weakly shiny, pronotum slightly alutaceous, shiny, elytron smooth, shiny. Color yellow except pronotum with black basomedian macula extended 4/5 distance to anterior pronotal margin, macula protruding medially, anterior border narrowly, deeply emarginate with yellow medially, anterolateral 2/5 of pronotum yellow; elytron black with 5 small, yellow spots arranged in rows of 2 each with apical spot, humeral spot small, triangular, scutellar spot rounded, mediolateral spot projected inward, discal spot oval, apical spot transversely rectangular with anterior border slightly emarginate ( Fig. 171 ); ventral surface with head, prosternum, meso- and metaventrite black; abdomen yellowish brown except median portions of ventrites 1-3 dark brown. 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 twice a diameter, elytral punctures larger than on pronotum, separated by less than to twice 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 slightly emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 6 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 wide, weakly 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 narrowly separated at apex, 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 flattened medially, extended forward at apex, ventrite and ventrite 2 with sparse, long pubescence and coarse, dense punctures; ventrites 3-6 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 nearly as long as paramere, asymmetrical, sides parallel from base to rounded apex; paramere Pem, widened from narrow base to wide apex, lower margin curved, apex appearing truncate but with faint trace of emargination ( Fig. 172, 173 ); sipho strongly curved in basal 1/2, without visible alae, basal capsule with inner arm short, slender, outer arm long, slender, sinuate, wider and longer than inner arm, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 174, 175 ).

Female. Similar to male except head black with median yellow spot at base of frons, pronotum entirely black except anterolateral angle triangularly yellow. Genitalia with spermathecal capsule short, weakly curved, slightly widened from base to rounded apex; bursal cap lost ( Fig. 176 ).

Variation. Length 2.4 to 2.5 mm. The Rio de Janeiro paratype has apex of basomedian macula very slightly emarginate with yellow, yellow pronotal spots about 2/3 the size of spots on the holotype.

Type material. Holotype male; ( Brazil), Sitio Bananal , Guarulhos, S. Paulo, 6.X.1957, J. Halik, 4544. ( USNM) . Paratypes; 3, 1, same data as holotype except date 19.IX.1957, J. Halik, 3104 ( USNM) ; 1, ( Brazil) 4268, Fry Rio Jan. , Fry Coll. 1905.100.( BMNH) ; 1, Fry, Rio Jan , Fry Coll, 1905.100., Cleothera trivialis Muls. ( BMNH) .

Geographical distribution. Brazil.

Remarks. This species has a dorsal color pattern identical to that of many other species of Cyrea , and only male genitalia will differentiate it from those species as well as others in the hexastigma group.

The specific name honors Natalia Vandenberg, fellow researcher in Coccinellidae systematics, in recognition of her fellowship and help in constructing this and many previous manuscripts.
