Asklepia surinamensis Zamorano & Erwin sp. n. Surinam pattern-wing beetle Figs 54 , 73 , 78

Holotype.

Surinam, Paramaribo, l’Hermitage, Surinam River, 5.8182°N, 55.1639°W, 2m, 14 July 1969 (N. Nieser)(CMNH: ADP130040, male).

Derivation of specific epithet.

The specific epithet, surinamensis, is a singular Latinized feminine noun in apposition, based on the name of the country in which these beetles are found.

Proposed english vernacular name.

Surinam pattern-wing beetle.

Diagnosis.

With the attributes of the genus Asklepia as described by Liebke (1938) and as noted above under the generic diagnosis, and medium-size to large-size for the genus (SBL = 2.841-2.99 mm). Adults with head fuscous, prothorax fulvous, elytral maculae fulvous or slightly aurantiacus in some individuals; elytron fuscous with a triangular flavous macula in the upper right corner of the proximal basal quadrant, broad flavous macula ending in hook crossing from medial lateral quadrant to left half of medial proximal quadrant, triangular flavous macula crossing from the lower right corner of apical proximal quadrant to lower half of apical lateral quadrant, apical and lateral margin fulvous; metepisternum fuscous, metasternum fuscous laterally flavous medially, abdominal sterna with III-VI, and epipleuron fulvous, abdominal sternum VII fuscous; legs flavotestaceous; antennal scape, pedicel and antennomere 3 testaceous, antennomeres 4-6 deeply infuscated, 7-11 white. Dorsal surface devoid of microsculpture, surface luster very shiny. Pronotum markedly convex and globose with lateral margin effaced except just anterior to hind angle and there a feeble bead; hind angle moderately prominent; anterior angles feebly produced; median line feebly defined. Elytral interneurs evident as continuous rows of widely spaced coarse punctures.

Description.

( Fig. 54 , 73 ). Habitus: Fig. 54 ). Size: [See also Table 25 ] Medium-size to large for the genus; ABL = 3.002-3.372 mm, SBL = 2.841-2.992 mm, TW (total width) 1.420-1.584 mm, LP = 0.575-0.626 mm, WP = 0.795-0.836 mm, LE = 1.709-1.803 mm. Color: See diagnosis above. Luster: See diagnosis above. Head ( Fig. 54 ): as in description for genus above. Prothorax. Pronotum ( Fig. 54 ) slightly broad, as wide as head across eyes (WH/WP, mean both sexes: 1.101), length about the same (LP/LH, mean both sexes: 1.093), wider than long (W/L, mean both sexes: 1.367); markedly cordiform and rounded, lateral margin effaced with seta at anterior third on slightly raised area; apex markedly constricted; anterior angle feebly produced, hind angle slightly produced and setose; median line feebly defined, apical transverse impressions punctate, punctures infuscated; surface smooth throughout. Pterothorax. Normal for genus, see description for genus above. Elytra moderate convex; at apical third twice as wide as head across eyes (WH/TW, mean both sexes: 0.542) and pronotum (WP/TW, mean both sexes: 0.4923). Elytral interneurs evident as continuous rows of widely spaced coarse punctures, punctures infuscated, interneurs continuous along length of entire elytron. Hind wings fully developed. Legs. Overall, normal for genus, see description for genus above. Abdominal sterna. Overall, normal for genus, see description for genus above. Male genitalia ( Fig. 73 , see Fig. 61 for attribute labels). Median lobe with phallobase moderate in length, about a fifth the length of shaft, basal opening moderate, oriented oblique to shaft. Shaft broad, slightly curved ventrally, dorsally sclerotized except for short ostium; in ventral aspect tapered toward broadly rounded apex, in lateral aspect, a rounded blunt apex. Left paramere very large and broad, right paramere moderately large and triangular; apex of left paramere lobate much, longer than right paramere about two-thirds the length of shaft (measured in left lateral aspect). Endophallus with one small median spine, and one very large distal spine. Female genitalia. Not investigated, presumably similar to that of Asklepia demiti sp. n.

Dispersal potential.

These beetles are macropterous and capable of flight; they are attracted to lights. They are moderately swift and agile runners.

Distribution.

( Fig. 78 ). This species has been found at only one location on the white-water system of the middle Surinam River drainage system. But that does not at all indicate its real distribution: as has been pointed out above, very small beetles are inadequately sampled, especially in the Neotropics.

Way of life.

See Erwin (1991) for a general description. Adults of this species are active in July.
