Loxandrus piceolus
Chaudoir, 1868:343
This taxon was described from a single specimen collected in «
Texas
». The
holotype
, a female in
MHNP
, is labelled «piceolus
Texas
C. Pilate
[handwritten]/ Muséum Paris [handwritten]». Both labels appears to be of recent origin
.
The specimen (SBL
¼
5.2 mm
; ABL
¼
about
5.8 mm
) belongs to the
agilis
group and along with the
lectotype
of
L. piciventris
(see next entry) rank among the smallest members of the group. Only some specimens of
L. accelerans
,
L. algidus
and
L. unilobus
Allen
have a SBL under 6.0 mm. Based on various structural details, the
holotype
of
L. piceolus
cannot be associated with any of the species mentioned. The wings are fully developed in the sole known specimen of
L. piceolus
. They are reduced in
L. unilobus
(
one paratype
studied) and along with
L. icarus
Will & Liebherr
, from
Virginia
, they are the only brachypterous
Loxandrus
species
in North America, though
L. straneoi
Will & Liebherr
, from
Mississippi
, is dimorphic in this respect (Will and Liebherr 1998).
