Tribe Paravaejovini Soleglad et Fet , trib. nov.

Type Genus. Paravaejovis Williams, 1980 .

Composition. This monotypic tribe, established here, includes the genus Paravaejovis .

Distribution. Mexico (Baja California Sur).

The monotypic genus Paravaejovis is endemic of the central-western and southwestern regions of Baja California Sur, and is the most southern taxon of subfamily Smeringurinae found in Baja California peninsula (see map in Fig. 197 ). The range of this genus is essentially disjunct from other members of its subfamily except for the two isolated species of Paruroctonus found in the Vizcaino Desert.

Diagnosis. Hemispermatophore lamellar hook well developed, extending well distal of the ventral trough, exaggerated by conspicuous basal constriction; mating plug barb toothed (after Stockwell, 1989); chelal trichobothrium Dt positioned distal of palm midpoint; femoral trichobothrium d distal to i, and e positioned near midsegment; major neobothriotaxy present on ventral aspect of the palm; three constellation array sensilla; chelicerae without denticles on the ventral edge of the movable finger or protuberances on the ventral aspect of the fixed finger; vesicular tabs reduced and rounded, distal granule vestigial to obsolete in adults.

Discussion. See discussion of genus below.
