Ojanguren-Affilastro, Andrés A., Ochoa, José A., Mattoni, Camilo I. & Prendini, Lorenzo, 2010, Systematic Revision of the granulatus Group of Urophonius Pocock, 1893 (Scorpiones, Bothriuridae), with Description of a New Species from Central Chile, American Museum Novitates 2010 (3695), pp. 1-44 : 5-6

KEY TO THE SPECIES IN THE GRANULATUS GROUP Of GENUS UROPHONIUS

1. Pedipalp femur, trichobothrium e situated proximal to dorsal macroseta M1 (fig. 10A); hemispermatophore, basal lobe with well-developed internal laminar extension, with internal notch ( fig. 8A )............................... U. granulatus

– Pedipalp femur, trichobothrium e situated in same axis as or distal to dorsal macroseta M1 (figs. 13A, 16A, 19A); hemispermatophore, basal lobe without internal laminar extension or, if laminar extension present, weakly developed, forming concave surface without internal notch ( fig. 8C, E, G )...................... 2

2. Pedipalp femur, trichobothrium e situated in same axis as dorsal macroseta M1 (fig. 13A); sternite VII and metasomal segment I, ventral surfaces without VSM carinae, only scattered granules evident; VL carinae weakly developed (♀), absent or almost indistinguishable (♂) ( figs. 3B , 4B ); hemispermatophore, distal lamina one third shorter than basal portion ( fig. 8C ).............. U. somuncura

– Pedipalp femur, trichobothrium e situated distal to dorsal macroseta M1 (figs. 16A, 19A); sternite VII and metasomal segment I, ventral surfaces with well-developed VSM carinae (more so in ♀) ( figs. 3C, D , 4C, D ); hemispermatophore, distal lamina similar in length to basal portion ( fig. 8F, H )................... 3

3. Color yellowish with dark brown spots ( fig. 15 ); carapace, anterior half weakly pigmented, with small dark spot medially on anterior margin ( fig. 2C ); metasomal segments IV and V, VL and VM pigmentation stripes not joining at posterior margins of segments; hemispermatophore, lobe region weakly developed, basal lobe forming slightly concave surface ( fig. 8E )..................... U. tregualemuensis

– Color dark brown with black spots ( fig. 18 ); carapace, anterior half densely pigmented, with a well-developed dark spot occupying almost entire anterior margin ( fig. 2D ); metasomal segments IV and V, VL and VM pigmentation stripes joining at posterior margins of segments; hemispermatophore lobe region well developed, basal lobe deeply excavated ( fig. 8G ).......... U. pizarroi , n. sp.
