Mycolybas sanguinosa
:

[chkl.]
Etymology:
sanguinosus—
blood red, in Latin, and
pennis—
wing, in Greek. The name refers to the reddish elytra and pronotum, according to the original description (
Motschulsky 1858
).
Diagnosis:
Elytra orange red (SSO-6-9°), pronotal color stronger (fig. 10). Body oval (fig. 12, 15, 19), slightly convex (fig. 11). Nine elytral striae, the most external absent on the anterior third, punctation very small (fig. 49, 50). Pronotal median lobe not truncate at scutellum (fig. 10, 19); legs scarlet orange (SO-7-10°—fig. 10); pro-, meso- and metacoxal lines present (fig. 60).
Redescription:
length:
5 mm
; thorax-abdomen: r = 0.7. Sternal color lighter and less strong than elytral or pronotal. Elytral pubescence absent.
Thorax (fig. 10, 19, 60): pronotum: r = 0.5; prosternum: prosternal suture complete. Scutellum: r=0.6. Sternum scarlet orange (SO-7-12°). Metasternum: r = 0.4, supracoxal lines present, metepisterna: r=5.0. Legs (fig. 12, 19): tibiae slightly expanded distally.
Elytra (fig. 49, 50): r = 2.4.
Abdomen: scarlet orange (SO-7-10°).
Material Examined: Colombia—
one exemplar, possibly
syntype
(
ZMUM
).
Intraspecific variation:
Unknown.
Geographical distribution:
Colombia
.
Discussion:
Mycolybas sanguinosus
does not match at least some characters of the genus (absence of coxal lines, truncate base of scutellum and tibiae moderately expanded distally). However,
M. sanguinosus
remains in
Mycolybas
until a comprehensive phylogenetic analysis is completed.
