Two-lights pattern-wing beetle Figs 32 , 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: ADP132555, male). Derivation of specific epithet. The specific epithet, derived from the Greek duofos , δυο (duo) = two, fɸσ (fos) = lights) is a noun used in apposition referring to the two bright spots on the elytra. Proposed english vernacular name. Two-lights 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 small to medium-sized for the genus (SBL = 2.248-2.941 mm). Adults with head and prothorax brunneus, elytral maculae aurantiacus; elytron fuscous with small rounded aurantiacus macula in the lower left corner of proximal basal quadrant, a small rounded aurantiacus macula in the upper left corner of proximal basal quadrant, maculae about the size of 1/4 of the quadrant, a semicircular aurantiacus macula in the proximal apical quadrant, macula does not reach the apical margin; proximal quadrants slightly paler compared with lateral quadrants; metasternum, abdominal sterna III-VI, and epipleuron brunneus, abdominal sternum VII paler; legs testaceous; antennal scape and pedicel testaceous, antennomeres 3-6 and basal half of 7 deeply infuscated, apical half of 7, 8-11 white. Dorsal surface devoid of microsculpture, surface luster very shiny. Pronotum cordiform, narrowly explanate, lateral margin beaded; anterior angles feebly produced, hind angle markedly prominent; median line moderately defined. Elytral interneurs evident as short discontinuous rows of widely spaced coarse punctures. Description. Habitus ( Fig. 32 ). Size : [See also Table 4 ] Small-sized for the genus; ABL = 2.433 mm, SBL = 2.248 mm, TW (total width) 1.124 mm, LP = 0.495 mm, WP = 0.666 mm, LE = 1.407 mm. Color : See diagnosis above. Luster : See diagnosis above. Head ( Fig. 32 ): as in description for genus above. Prothorax . Pronotum ( Fig. 32 ) moderately broad, as wide as head across eyes (WH/WP: 0.939), longer than head (LP/LH: 1.423), wider than long (PW/PL: 1.397); markedly cordiform and explanate, lateral margin beaded with seta at anterior third; base markedly constricted; anterior angles feebly produced, hind angle markedly prominent, produced and setose; median line markedly defined, apical transverse impressions 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/MW: 0.489) and pronotum (WP/MW: 0.521), longer than wide. Elytral interneurs evident as short rows of discontinuous widely spaced coarse punctures. 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 . The male paratype was dissected for illustrating the male aedeagus; however, it was damaged in the process and we were hesitant to dissect the holotype at this time. We do note the presence of multiple spines on the endophallus. 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 Amazon 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 lowland rainforest during the transition from rainy to dry seasons Other specimens examined. None.
