Distribution
This species is known from the
area around the Rancho Grande Biological
Station,
north
of
Maracay
in
Venezuela. A single old specimen is
labeled as having been taken at Caracas.
Biology
Specimens were collected in flight intercept traps in montane cloud forest between
1100 and
1450
m and in lindgren traps at
1800 m
, from March through June.
Comments
This species is named after my friend and colleague James Steven Ashe, deceased on
27 December 2005
. Steve was a wonderful field companion and friend and I’ll always miss his youthful exuberance and enthusiasm upon making exciting new discoveries in the field; field trips are not the same without him. His widespread use of flight intercept traps led to the collection of many specimens of
Alloscolytroproctus
, including numerous specimens of this species that now bears his surname. Of the three species known this one is the least distinctive. The elytra are not distinctly modified as in
A
.
peruanus
or
A
.
dominicae
. All specimens examined have the same elytral color pattern, with both posterior and anterior red maculations but an entirely black pronotum.
