Clutch size in the "vorhiesi" group of the genus Vaejovis

Richard Ayrey has recently published an interesting article documenting the clutch size for the 12 species in the "vorhiesi" group of the genus Vaejovis C. L. koch, 1836 (Vaejovidae). The article has color pictures of females with scorplings for many of the species.

A total of 2,287 newborn scorpions were counted and photographed on 100 females of all 12 described species of  the  “vorhiesi”  group  of  the  genus  Vaejovis  (Scorpiones:  Vaejovidae)  found  in  Arizona,  USA,  and  several  undescribed species. Average clutch size for the “vorhiesi” group and for each individual species is reported. The  data clearly shows that the larger species have more young, per parturition, than the smaller species. Representative  photographs are presented for each species discussed.
