SPECIES
:
Staphylinus chloropterus

.
COMMENTS: Members of this genus share the following character states: (
1
) mandibles with similarly developed teeth, each with large tridentate middle tooth (individual dents not at same plane) and a small tooth basad of it in a deep, subrectangular indentation (
fig. 124
); (
2
) mandibular prostheca appearing bilobed or even multilobed, with extensive basal group, and long distal group of ciliae originating on separate supporting arm (
fig. 12
); (
3
) mentum with anterolateral portions (bearing two anterolateral setae) each obliquely deflected at an angle and therefore not at same level as disc of mentum, separated from it by obtuse carina (
fig. 123
); and (
4
) postmandibular ridge almost reaching infraorbital puncture, running close to eye basally, infraorbital puncture situated three to four diameters from margin of eye.
Further character states include: maxillary and labial palpi both with last segment asetose, fusiform; mandibles each with dorsolateral ridge as in
Ontholestes
or
Thoracostrongylus
; submentum with anterior margin not beaded; lateral end of nuchal ridge distinctly, but moderately, removed from nuchal constriction, directed toward level of transverse postgenal ridge; epimeron of prothorax well developed, projecting triangularly (
fig. 111
); prosternum moderately prominent with broadly rounded slope anteriad, with prominent, arcuate carina continuing evenly onto furcasternum; mesosternum with long serial setae originating behind small elevations in moreorless Vshaped pattern (
fig. 122
), mesosternal intercoxal process rather acute apically, mesocoxal acetabulum moderately impressed behind; metasternum more or less horizontal, with little difference in convexity between projections and disc.
