Subfamily Smeringurinae Soleglad et Fet ,

subfam. nov.

Type Genus. Smeringurus Haradon, 1983 .

Composition. This subfamily, established here, includes the tribes Smeringurini and Paravaejovini .

Distribution. North America: Canada (southwest), Mexico (north, Baja California), USA (northwest, southwest).

Diagnosis. Scorpions in the subfamily Smeringurinae can be distinguished by the following characters: genital operculum sclerites of female divided on posterior two-fifths to one-half, operating separately, not connected to mesosoma on extreme distal aspect, but more midpoint; ib–it positioned proximal to basal inner denticle (ID), but never basally on finger; chelal trichobothria V 2 –V 3 distance approximately twice as long as V 1 –V 2; fixed finger trichobothria dsb and dst positioned proximal of esb and est, respectively; leg tarsus with one pair of ventral distal spinules; setal combs present on legs; number of constellation array sensilla low, exhibiting 2–3 sensilla; cheliceral ventral edge of movable finger usually with denticles or serrations; serrula vestigial to non-contiguous, weakly developed; dorsal carinal terminus of metasomal segments I–III rounded, not terminating with an enlarged denticle; dorsolateral carinae of metasomal segment IV not flared at the terminus, essentially coinciding with articulation condyle; carapace anterior edge variable, from straight to a conspicuously convexed; median eye tubercle and eyes enlarged, 21–30 % as wide as carapace at that point.
