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.
