Wd. Sissom, A NEW SPECIES OF VAEJOVIS (SCORPIONES, VAEJOVIDAE) FROM WESTERN ARIZONA, WITH SUPPLEMENTAL NOTES ON THE MALE OF VAEJOVIS-SPICATUS HARADON, The Journal of arachnology, 21(1), 1993, pp. 64-68
A new species of Vaejovis is described from two localities along the C
olorado River in western Arizona. The species is related to Vaejovis s
picatus Haradon, to which it is compared. The first known male specime
n of V. spicatus is briefly described, and comments on its hemispermat
ophore are provided. Hemispermatophore morphology of V. spicatus sugge
sts a close phylogenetic relationship of these two species with member
s of the genus Serradigitus, although they lack several features consi
dered diagnostic for that genus.
