Indoquedius recticollis (Scheerpeltz, 1965)

Figs 1F, 4C–D, 7C

Quedius (Indoquedius) recticollis Scheerpeltz, 1965: 294 .

Diagnosis

Among members of the Bipunctatus group, I. recticollis can be easily recognized by the combination of: impunctate middle areas and posterior half to two-thirds of abdominal tergites III–VI (Fig. 4D); the sparse but regularly spaced elytral punctures (Fig. 4C); and the darkened middle and hind femora (Fig. 1F). Indoquedius recticollis is somewhat similar to I. dispersepunctatus in the sparsely punctate abdomen and darkened middle and hind femora but can easily be distinguished by the darkened first antennomere, much finer and regularly spaced elytral punctures, the longer elytra, the coarser abdominal punctures and the pale apices of the abdominal tergites. These two species may be related as they share a similar shape of female tergite X (Fig. 7A, C).

Type material

Redescription

Similar to Indoquedius dispersepunctatus and differing only in the following: antennomere 1 darkened on dorsal surface; abdominal tergites broadly paler apically; head with two parocular punctures; temples slightly smaller; antennomere 3 slightly longer than 2, about 1.4 ×; antennomere 10 distinctly broader at apex, shape more obviously triangular; pronotum slightly transverse, more strongly convergent anteriad; scutellum longer, more typical of the genus, densely punctate with only outer margins impunctate; elytra longer at both suture and at sides, at sides distinctly longer than pronotum at midline; elytral punctures much finer and less strongly impressed, regularly distributed though sparse, separated by more than one puncture diameter; abdominal punctation coarser, tergite III with sparse punctures across disc, middle of tergites impunctate or nearly so on tergites III–VI; female tergite X slightly less strongly narrowed to apex, which is broader overall and more shallowly and broadly emarginate (Fig. 7C).

Distribution

Known only from the type locality in Myanmar (Kachin).

Remarks

The type material contains only the female holotype, which was dissected. Based on external morphology, this species does not appear to have any synonyms and can be recognized based on external morphology alone.
