Name
Liogluta atriventris (Casey, 1906) – Wikispecies link – Pensoft Profile
- Athetota atriventris Casey, 1906: 336. As Atheta (Liogluta): Bernhauer and Scheerpeltz 1926[1]: 656; Moore and Legner 1975[2]: 355. Lectotype (male): Canada, Victoria, Vancouver Island; atriventris Casey; Type USNM 39475; H.F. Wickham, Casey Bequest 1925 (USNM). Present designation.
Diagnosis
(based on male lectotype). This species may be distinguished by the following combination of characters: small body size, length 2.8 mm; head and abdomen dark brown, pronotum, elytra and legs reddish-yellow (Fig. 86); integument glossy with weak meshy microsculpture; pronotum and elytra with moderately dense punctation and pubescence, elytra with very fine micro-granulation (Fig. 86); head subquadrate, slightly narrower than pronotum; large eyes, each about as long as postocular region in dorsal view (Fig. 86); antennae of the holotype are partially damaged and cannot be completely described, but fifth and sixth articles suggest that missing funicle articles are subquadrate; pronotum slightly transverse, widest near the middle (Fig. 86); elytra wider and slightly longer than pronotum (Fig. 86); abdomen subparallel, about as wide as elytra (Fig. 86). Male. Apical margin of tergite VIII with broad, truncate projection in middle two-thirds bounded laterally by small tooth-like processes, apical margin crenulate (Fig. 88); apical margin of sternite VIII evenly broadly parabolic from base (Fig. 89); median lobe of aedeagus with tubus bent slightly ventrad at middle, apical part relatively broadly rounded in lateral view (Fig. 87). Female. Unknown.
Liogluta atriventris may be distinguished from the other species of the granulosa group by the following combination of characters: body size small, length 2.8 mm; elytra slightly longer than pronotum (Fig. 86); pronotum glossy with weak microsculpture (Fig. 86); shape of median lobe of aedeagus different in lateral view (Fig. 87), and projection on apical margin of male tergite VIII crenulate, with tooth-like processes laterally (Fig. 88).
Natural history
Unknown.
Distribution
Known only from Vancouver Island, British Columbia.
Comments
This species is known only from one damaged male specimen. More specimens, including females, are needed for study to confirm the status of this species.
