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
(

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

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
