DIAGNOSIS. A member of the ‘ Grosphus ’ group differentiated as follows: small-sized scorpions, adults ca. 24–30 mm in length; pedipalp finger granule rows 8–9 (Fig. 612–613, 616), movable finger with no more than 3 external subdistal granules; femur trichobothrium d 2 located on dorsal, carinal or internal surface; chela manus with petite trichobothrium Eb 3 usually well separated from Eb 2, by more than half the distance between Eb 1 and Eb 2 (Figs. 25–27); manus trichobothrium V 2 strongly displaced internally relative to V 1; higher pectinal tooth counts: ♂ 27– 31, ♀ 27–29 (Figs. 28–31); basal pectinal tooth of females wide, oval, only slightly longer than other teeth (Fig. 614); hemispermatophore capsule short, posterior lobe rounded, without lanceolate extension (Fig. 70); sternites with moderately narrow spiracles (Figs. 610, 614); metasoma I with ventromedian carinae moderate, finely granulate; telson with elongate vesicle, without subaculear tubercle; legs with ventral surface of telotarsus densely setose, with> 20 long, filiform setae (Figs. 618–619); telotarsus with dorsal terminal process very small; cuticle with strong UV fluorescence.

REMARKS. Neogrosphus shares some primitive characters with Grosphus, and some derived characters with Teruelius gen. n. (summarized in Table 4). One interpretation of this is that Neogrosphus is descended from an intermediate stage in the evolution of Teruelius gen. n. from a Grosphus - like ancestor. Other characters, such as small size, internal displacement of V 2, reduced dorsal terminal process of telotarsus and elongated telson appear to be autapomorphies for the genus.
