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.

Size
:
[See also

] 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.

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.
