Differential Diagnosis.
The habitus of this species (
Fig. 52
) is very similar to that of other members of the
Costatus
group; reliable determinations will be based on examination of the aedeagus. The aedeagus has arching parameres somewhat similar to those of
E. apocinus
, but otherwise the aedeagi of the two species are quite dissimilar (
Figs. 48
,
56
). The aedeagus of
E. mucronatus
is smaller and narrower, the median lobe is more acutely pointed apically, and the parameres are arched differently and, in lateral view, lack the sinuations present in
E. apocinus
.
Description
.
Size:
holotype
(length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.25/0.78; head (width) 0.39; pronotum 0.50/0.52; elytra 0.88/0.78. Habitus and sculpture as illustrated (
Fig. 52
). Head black, dorsum red, venter light brown, maxillary palpi testaceous. Eye with ca. 3–4 facets between canthus and posterior margin. Protibiae slightly arcuate. Elytral punctures each with a granule at anterior and posterior margins, granules usually not linking punctures. Metaventral depression moderately deep, ca. eight granules along base.
Etymology.
Named in reference to the pointed apex of the median lobe of the aedeagus.
Distribution.
Currently known from
Mexico
and
Honduras
(

).
