Holotype.

Brazil, Amazonas, 20 km SW Manaus, 3.166°S, 60.234°W, 47m, 6 November 1969 (J.M. Campbell, B.A. Campbell)(NMNH: ADP132519, male).

Derivation of specific epithet.

The specific epithet, matomena, is derived from the Greek ματωμενα (bleeding) and used as an adjective in reference to the blood-red color of the head and elytra of these beetles.

Proposed english vernacular name.

Reddish 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 = 2.189-2.551 mm). Adults with head and prothorax fuscous, elytral maculae if present aurantiacus; elytron fuscous with a small semicircular aurantiacus macula in the proximal apical quadrant, macula does not reach the apical margin; 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 feebly produced, hind angle angulated, very prominent; median line moderately defined. Elytral interneurs evident as continuous rows of fine closely spaced punctures.

Description.

( Figs 37 , 63 ). Habitus: ( Fig. 37 ). Size: [See also Table 9 ] Small to medium-sized for the genus; ABL = 2.476-2.961 mm, SBL = 2.189-2.551 mm, TW (total width) 0.575-0.726 mm, LP = 0.447-0.546 mm, WP = 0.603-0.730 mm, LE = 1.411-1.622 mm. Color: See diagnosis above. Luster: See diagnosis above. Head ( Fig. 37 ): as in description for genus above. Prothorax. Pronotum ( Fig. 37 ) moderately broad, as wide as head across eyes (WH/WP, mean males: 1.011), longer than head (LP/LH, mean males: 1.387), wider than long (W/L, mean males 1.345); markedly cordiform and explanate, lateral margin beaded with seta at anterior third; base markedly constricted and lobed medially; anterior angles feebly 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 males, 0.520) and pronotum (WP/TW: mean males, 0.514), longer than wide. Elytral interneurs evident as rows of continuous fine punctures closely spaced; 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. 63 , 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 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 in the transition from rainy to dry seasons.
