Asklepia campbellorum Zamorano & Erwin sp. n. Campbells’ pattern-wing beetle Figs 30 , 58 , 77

Holotype.

Brazil, Amazonas, 20 km SW Manaus, 3.166°S, 60.234°W, 47m, 6 November 1969 (J.M. Campbell, B.A. Campbell)(NMNH: ADP133032, male).

Derivation of specific epithet.

The specific epithet, campbellorum, is an eponym based on the family name of Milt and Beverly Campbell †, collectors of the type series.

Proposed english vernacular name.

Campbells’ 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 to large-sized for the genus (SBL = 2.941-3.198 mm). Adults with head and prothorax brunneus, elytral maculae aurantiacus; elytron fuscous with a small rounded aurantiacus macula in the lateral apical quadrant and proximal apical quadrant and an oval aurantiacus macula in the proximal apical quadrant, maculae reach the sutural area. Color pattern variable, maculae in the apical quadrants are connected, forming a single macula or completely absent in some individuals. Metasternum, abdominal sterna III-VI, and epipleuron brunneus, abdominal sternum VII paler; legs testaceous; antennal scape and pedicel testaceous, antennomeres 3-7 deeply infuscated, 8-11 white. Dorsal surface devoid of microsculpture, surface luster very shiny. Pronotum cordiform, narrowly explanate, with medial lobe at base, lateral margin beaded; anterior angles markedly produced, hind angle angulate, very prominent; median line moderately defined. Elytral interneurs evident as rows of continuous closely spaced fine punctures.

Description.

( Figs 30 , 58 ). Habitus: ( Fig. 30 ). Size: [See also Table 2 ] Small-size to large-size for the genus; ABL = 3.17-3.61 mm, SBL = 2.182-3.198 mm, TW (total width) 1.106-1.824 mm, LP = 0.467-0.691 mm, WP = 0.611-0.956 mm, LE = 1.386-2.069 mm. Color: See diagnosis above. Luster: See diagnosis above. Head ( Fig. 30 ): as in description for genus above. Prothorax. Pronotum ( Fig. 30 ) moderately broad, slightly wider than head across eyes (WH/WP, both sexes: 0.966), longer than head (LP/LH, mean both sexes: 1.414), wider than long (W/L, mean both sexes: 1.395); markedly cordiform and explanate, lateral margin beaded with seta at anterior third; base markedly constricted and lobed medially; anterior angles markedly produced, hind angle markedly prominent, produced and setose; median line moderately defined, apical transverse impression punctate, punctures infuscated; surface smooth throughout. Pterothorax. Normal for genus, see description for genus above. Elytra slightly convex; at apical third twice as wide as head across eyes (WH/TW, mean both sexes: 0.492) and pronotum (WP/TW, mean both sexes: 0.510). Elytral interneurs evident as rows of continuous closely spaced fine punctures; punctures homogeneous. 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. 58 , see Fig. 61 for attribute labels). Median lobe with phallobase short about a fourth the length of shaft, basal opening small, oriented parallel to shaft. Shaft broad, slightly curved ventrally, dorsally sclerotized except for short ostium; in ventral aspect tapered toward rather narrowly acute apex, in lateral aspect, a rounded apex. Parameres: left very large and broad, right small and triangular; apex of left paramere lobate much longer than right paramere about half the length of shaft (measured in left lateral aspect). Endophallus with 7 preapical spines. Female genitalia. Not investigated, presumably similar to that of Asklepia demiti sp. n.

Dispersal potential.

These beetles are macropterous and probably capable of flight. They are moderately swift and agile runners.

Distribution.

( Fig. 77 ). This species has been found at only one location on the shore of a small lake near the middle of the Amazon River drainage system. But that does not at all indicate its actual 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 lowland rainforest in the transition from rainy to dry seasons.
