Hyperaspis mariae Crotch, 1874:220 ; Korchefsky 1931:192; Blackwelder 1945:447; Gordon 1987:27.

Description. Male. Length 2.8 mm, width 2.4 mm; body rounded, convex. Dorsal surface with head alutaceous, dull, pronotum and elytron smooth, shiny. Color yellow except pronotum with 5 dark brown maculae, basomedian macula short, wide, extended about 1/4 distance to apical pronotal margin, anterior margin of macula sinuate, 1 obliquely oval spot present on each side of middle of pronotum, 1 small, irregularly round spot present medially near lateral pronotal margin; elytron with brown sutural border from scutellum to apex, border widened anterior to middle, apical margin narrowly bordered with brown, 7 discrete brown spots present, humeral spot small, round, scutellar spot elongate oval, discal spot oval, spot on middle of elytron irregularly square, mediolateral spot irregularly, obliquely oval, lateral spot on apical declivity irregularly rectangular, inner spot on apical declivity oval ( Fig. 109 ); ventral surface with head, prosternum, meso- and metaventrites dark brown; abdomen yellow except median 1/3 of ventrites 1-4 brown. Head punctures small, separated by a diameter or less, each puncture smaller 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 less than to twice a diameter; metaventral punctures larger than on elytron, separated by a diameter or less medially, slightly larger, nearly contiguous in lateral 1/2. Clypeus 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 slightly curved, basal margin without trace of bordering line medially. Epipleuron wide, grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin arcuate, smooth, sponda extended beyond angle. Carinae on prosternal process widely separated at apex, convergent, joined just before prosternal base, connected to prosternal base by single, short carina. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite flattened along posterior ventrite margin, extended forward at apex, ventrite with sparse, long pubescence and coarse punctures medially, punctures becoming denser laterally; ventrites 2-6 pubescent throughout, punctures fine, sparse medially, becoming denser laterally; 5th ventrite depressed in median 1/3, apex emarginate; 6th ventrite deeply depressed medially, apex shallowly emarginate with lateral angle rounded. Apical tergite finely, densely punctured, apex weakly emarginate. Genitalia with basal lobe slender, about 2/3 as long as paramere, asymmetrical, sides slightly convergent from base to apex, apex rounded; paramere Pav, widened from base to obliquely rounded apex, upper margin with shallow, median emargination and large, sclerotized projection, or “ear” slightly posterior to apex; sipho strongly curved in basal 2/3, without visible alae, basal capsule with inner arm long, slender, apex slightly rounded, outer arm about as wide and slightly longer than inner arm, with accessory piece, basal border widely, shallowly emarginate ( Fig. 110, 111 ).

Female. Similar to male except head with clypeus brown. Genitalia with spermathecal capsule slightly elongate, slender, widened anterior to base, narrowed to narrowly rounded apex of cornu; bursal cap oval, with 2 weakly sclerotized arms, apical strut long, narrow, slightly widened apically ( Fig. 112 ).

Remarks. The dorsal color pattern of C. mariae with 7 brown spots on each elytron distinguishes it from other species in the emiliae group except C. maculosa , as well as most other species of Cyrea . These spots are small and discrete in C. mariae , larger and with a tendency to coalesce in C. maculosa . The short prosternal carinae extended just past the middle of the prosternal process is also distinctive for this species. See remarks under C. maculosa .
