Loxandrus accelerans
Casey, 1918:386
This
taxon was described from an unspecified number of specimens collected at «Galveston,
Texas
».
Casey’s
collection in
USNM
contains two conspecific specimens, both females, under that name.
One
of them, herein selected as the
lectotype
, is labelled «Tex/Casey bequest 1925/Type

The
lectotype
(SBL
¼
5.6 mm
; ABL
¼
about 6.0 mm) belongs to the
agilis
group. I cannot associate it with any species described by Allen (1972) but by its size and shape of pronotum, particularly the non protruding front angles, it looks more similar to members of
L. algidus
Allen
than to any other species seen. It differs from the
holotype
and
one paratype
of
L. algidus
studied in having the antennae and legs entirely yellowish (
6
reddish-black in
L. algidus
), the elytral striae slightly shallower and less coarsely punctate, and the microsculpture on the proepisternum and metepisternum coarser.
