Marituba pattern-wing beetle Figs 47 , 78 Holotype. Brazil , Para , Marituba, Ananindeua, 1.3712 °S , 48.3689°W , 10m, (F.M. Oliveira, P. Wygodzinsky)(AMNH: ADP132494, female). Derivation of specific epithet. The specific epithet, marituba , is a singular Latinized feminine noun in apposition, based on the name of the place where these beetles are found. Proposed english vernacular name. Marituba 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 for the genus (SBL = 2.732 mm). Adults with head and prothorax aurantiacus, elytral maculae fulvous; elytron brunneus with scutellar area flavous, a broad flavous macula transversely oriented in the medial lateral quadrant, barely prolonged into the medial proximal quadrant, and a narrow oval flavous macula in the proximal apical quadrant, macula extended to the sutural area; metasternum, abdominal sterna III-VI, and epipleuron flavotestaceous, abdominal sternum VII infuscated; legs testaceous; antennal scape and pedicel fulvous, antennomeres 3-7 infuscated, 8-11 white. Dorsal surface devoid of microsculpture, surface luster very shiny. Pronotum markedly convex with lateral margin effaced except just anterior to hind angle and there a simple bead; hind angle slightly prominent; median line feebly defined. Elytral interneurs effaced from the greater part of the elytron, only visible as scattered coarse punctures. Description. ( Habitus , Fig. 47 ). Size : [See also Table 19 ] Medium-size for the genus; ABL = 2.924 mm, SBL = 2.732 mm, TW (total width) = 0.820 mm, LP = 0.605 mm, WP = 0.768 mm, LE = 1.694 mm. Color : See diagnosis above. Luster : See diagnosis above. Head ( Fig. 47 ): as in description for genus above. Prothorax . Pronotum ( Fig. 47 ) moderately broad, as wide as head across eyes, (WH/WP: 1.069), longer than head (LP/LH: 1.398), slightly wider than long (WP/LP: 1.268); markedly cordiform and explanate, lateral margin beaded with seta at anterior third; base markedly constricted with medial lobe at base; anterior angles moderately produced, hind angle slightly produced, a right angle, and setose; median line markedly defined, basal and 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/TW: 0.521) and pronotum (WP/TW: 0.488), longer than wide. Elytral interneurs evident as rows of continuous 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 . Male unknown. 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 attracted to lights. They are moderately swift and agile runners. Distribution. ( Fig. 78 ). This species has been found at only one location on a white-water system on the lower Rio Amazonas. 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. Nothing is known about the way of life of this species. Other specimens examined. None.
