Distribution: previously
known from South America. Two species are now known to occur
in Panama with one reaching Costa Rica and Nicaragua (Ratcliffe 2003a).
|
|
|
|
Composition: 5
species.
|
|
Diagnosis: Erioscelis differs from Stenocrates in its
larger clypeus (small and trapezoidal in Stenocrates, pronotum
widest before the middle (widest at the middle in Stenocrates),
and elytra with indistinctly paired rows of punctures (distinct in Stenocrates).
|
|
|
|
|
Larvae: the immature stages are unknown for all species
in the genus.
|
|
Biological notes: life history information is also sparse, although
adults of E. columbica Endrödi
have been observed feeding on the flowers of aroids in Panama. Adults
are occasionally attracted to lights, but if they are hidden within the
spathe of an aroid inflorescence, then they may not see the lights. This
could account for low light trapping success with species of Erioscelis.
