Genus: Asklepia
Name
Asklepia biolat Erwin & Zamorano sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Holotype
Perú, Madre de Dios, BIOLAT Biological Station, Pakitza, Zone 9, 11.8931°S, 71.2564°W, 382m, 1 October 1989 (T.L. Erwin)(MUSM: ADP132509, male).
Derivation of specific epithet
The specific epithet, biolat, is used as a noun in apposition based on the acronym of the Smithsonian Institution’s past program “Biodiversity in Latin America” (BIOLAT) which sought to field-train young Latin American biology students in biodiversity techniques and did so for more than 200 of them between 1987 and 1991 in Perú and Bolivia. These beetles were collected under the auspices of the BIOLAT Program.
Proposed english vernacular name
Biolat pattern-wing beetles.
Diagnosis
With the attributes of the genus Asklepia as described by Liebke (1938)[1] and as noted above under the generic diagnosis, and medium to large-sized for the genus (SBL = 2.787–3.247 mm). Adults with head, prothorax, and elytral maculae (slightly fulvous in some individuals); elytron fuscous with scutellar area, basal third of disc, and apical sutural area aurantiacus; metasternum, abdominal sterna III-VI, and epipleuron flavotestaceous, abdominal sternum VII infuscated; legs testaceous; antennal scape and pedicel testaceous, antennomeres 3-6 and base of 7 deeply infuscated, apical half of 7 and 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 acute, not very prominent. Elytral interneurs evident as rows of subsurface dots in the substantially transparent elytron.
Description
(Fig. 40, 65). Habitus: (Fig. 40). Size: [See also Table 12] Large-size for the genus; ABL = 3.127–3.421 mm, SBL = 2.787–3.247 mm, TW (total width) 0.694–0.908 mm, LP = 0.637–0.746 mm, WP = 0.747–0.935 mm, LE = 1.750–2.035 mm. Color: See diagnosis above. Luster: See diagnosis above. Head (Fig. 40): as in description for genus above. Prothorax. Pronotum (Fig. 40) moderately broad, not quite as wide as head across eyes (WH/WP, mean both sexes: 1.007), longer than head (LP/LH, mean both sexes: 1.603), slightly wider than long (WP/LP, mean both sexes: 1.244); markedly cordiform, lateral margin effaced with seta at anterior third on slightly raised area; base markedly constricted; hind angle slightly acutely produced and setose; surface markedly smooth throughout. Pterothorax. Normal for genus, see description for genus above. Elytron twice as wide as head across eyes (WH/TW: mean, both sexes, 0.522), and pronotum (WP/TW, mean both sexes: 0.518), longer than wide, moderately convex, intervals and interneurs effaced (see diagnosis above), interneur 2 with 7 setae, interneur 5 with two setae. Hind wings dimorphic; most specimens studied are brachypterous. Legs. Overall, normal for genus, see description for genus above. Abdominal sterna. Overall, normal for genus, see description for genus above. Male genitalia (Fig. 65, see Fig. 61 for attribute labels). Median lobe with phallobase moderate in length, about a fifth the length of shaft, basal opening large, oblique to shaft. Shaft broad, slightly curved ventrally at distal sixth, dorsally sclerotized except for short ostium; in ventral aspect tapered toward rather moderately rounded apex, in lateral aspect, a rounded blunt apex. Left paramere 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 one very large preapical spine. 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. 78). This species has been found at locations on the white-water system of the upper 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)[2] for a general description of the genus. Adults of this species are active in all seasons in lowland rainforest along small stony stream margins in wet leaf litter on sand and are active at night. They also inhabit wet leaf litter lying on half submerged tree trunks and branches. In addition, they climb culms of Paspalum grasses at river edges.
