Name
Asklepia grammechrysea Zamorano & Erwin sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Holotype
Perú, LORETO, circa Pithecia, Cocha Shinguito, 5.1757°S, 74.655°W, 111m, 16 August 1989 (T.L. Erwin, G.P. Servat)(MUSM: ADP133151).
Derivation of specific epithet
The specific epithet, grammechrysea derived from the Greek γραμμή (grammae) = line, κριχισηα (chrysea) = golden), is a noun in apposition referring to the yellow (flavous) line on the pronotum.
Proposed english vernacular name
Golden-line pattern-wing beetle.
Diagnosis
With the attributes of the genus Asklepia as described by Liebke (1938)[1] and as noted above under the generic diagnosis. Individuals of this species present a wide range of sizes from small to large for the genus (SBL = 2.265–3.736 mm). Adults with head fuscous, pronotum bicolored, its lateral areas fuscous, medial area aurantiacus; elytral maculae aurantiacus, elytron fuscous with an elongated horizontally oriented flavous macula crossing basal lateral and proximal quadrant, sutural area fuscous, and with a semicircular flavous macula in the apical proximal quadrant, sutural area fulvous, lateral margin of medial and apical quadrants fulvous; metasternum, abdominal sterna III-VI, basal half of sternum VII and epipleuron brunneus, apical half of abdominal sternum VII paler; legs fulvous; 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, apical margin slightly concave lateral margin beaded; hind angle markedly prominent; median line markedly defined. Elytral interneurs evident as continuous rows of fine closely spaced punctures; punctures fuscous; basal and apical punctures each with infuscated halo.
Description
(Figs 33, 60). Habitus: (Fig. 33). Size: [See also Table 5] Small to large-sized for the genus; ABL = 2.336–3.78 mm, SBL = 2.265–3.736 mm, TW (total width) 1.382–2.216 mm, LP = 0.481–1.016 mm, WP = 0.659–1.065 mm, LE = 1.440–2.381 mm. Color: See diagnosis above. Luster: See diagnosis above. Head (Fig. 33): as in description for genus above. Prothorax. Pronotum (Fig. 33) moderately broad, as wide as head across eyes (WH/WP, mean both sexes: 1.002), larger than head (LP/LH, mean both sexes: 1.512), about as wider than long (WP/LP, mean both sexes: 1.381); markedly cordiform and explanate, lateral margin beaded and fuscous with seta at anterior third; base markedly constricted and lobed medially; anterior angles moderately produced, hind angle markedly produced and setose; median line markedly defined, basal and apical transverse impressions punctate, punctures fuscous; surface smooth throughout.
Pterothorax. Normal for genus, see description for genus above. Elytra slightly convex; at apical third twice as width as head across eyes (WH/TW, mean both sexes: 0.481) and pronotum (WP/TW, mean both sexes: 0.493), longer than wide. Elytral interneurs evident as continuous rows of fine closely spaced punctures; punctures each with a fuscous halo in the basal and apical proximal quadrant of elytron. 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. 60, 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 rounded 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 locations on black-water systems across the northern and western areas of the 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
Adults of this species are active in lowland Igapó rainforest during the rainy season. They have been found in wet leaf litter at the edge of small streams and lake shores as well as in old levee forests of Attalea palms near a black water river; they also occur on mud with grasses and among crumbly clods of yellowish clay at salt licks, as well as near rotting tree trunks at the water’s edge in low lying inundation forest at the edge of a black water lake and on sandy shorelines with matted rhizomes and dry leaf litter.
