Comments:
An additional locality from
Vanin (1986)
is:
Dominican Republic
:
Arroyo
Hondo (near Ciudad Trujillo); this specimen was not examined. This species is very similar to
S. perezi
and was confused with the latter by me during early manuscript preparation. The rostrum is shorter in both sexes in
S. championi
and the basal sclerite of the internal sac is different (compare figs. 23 and 59).
Vanin (1986)
noted a similarity to
S. tinamus
, which has a less deeply and densely punctate pronotum and a different basal sclerite of the internal sac.
Sicoderus championi
exhibits some variation in the extent of punctation of the pronotum, especially dorsally on the disc which can vary from widely spaced and shallow to deep and subcontiguous, forming weak to distinct striolae.
This species appears to be common and widespread in low elevation or coastal areas throughout
the Dominican
Republic.
