Table 1: Variation of pectinal tooth count in Rhopalurus caribensis sp.n. , including data from the types, additional specimens herein recorded and Botero-Trujillo & Fagua (2007). Abbreviations: number of pectines (N), standard deviation (SD). Diagnosis (emended): species of moderately small size (males 38–40 mm , female 43–55 mm ) for the genus. Body pale yellow to light orange brown, with metasomal segment V moderately infuscate and a diffuse pattern of gray spots over carapace and tergites (confluent and darker in earlier juveniles); metasoma ventrally with all carinae infuscate and a thin, dark line between the ventrosubmedian carinae. Pedipalp chelae robust in both sexes, more conspicuously in males; fingers without basal lobe/notch combination, but with subtle scallop in adult males; fingers with eight principal rows of granules, flanked by a few supernumerary granules. Sternite III and pectines with stridulatory apparatus greatly reduced; sternite V without smooth patch. Metasoma distally incrassate on both sexes, much more conspicuously in males; telson vesicle small, subaculear tubercle vestigial, blunt and far removed from the base of aculeus. Pectinal tooth count 22–25 (mode 24) in males, 19–23 (mode 21) in females. New Records: COLOMBIA : La Guajira Department , Palomino, at Magdalena border, September 2008 , leg. C. A. Roncallo , 1♀ (Sco-0419); Ranchería El Pasito , 3 km northeast of Riohacha , 5 December 2008 , leg. J. Zubiria , 1♀ (Sco-0415), Riohacha downtown, 27 September 2008 , leg. J. Brito ; 1 juvenile (Sco-0417), Riohacha, Colegio Sagrado Corazón, km 1 Maicao road, 16 July 2008 , leg. C. A. Roncallo , 2 juveniles (Sco- 0394); Riohacha, 7 km beyond Colegio Sagrado Corazón, path to Rancherías river , 11 February 2009 , leg. C. A.

Roncallo , 1 juvenile (Sco-0418); Ranchería Irrujunai, km 12 El Pájaro path, on Maicao road, 2 January 2008 , leg. C. A. Roncallo , 1♂ , 3♀♀ , 1 juvenile (Sco-0393) . VENEZUELA : Zulia State , Mara Municipality , Cuatro Bocas , La Sierrita , June 1998 , 1♂ (Sco-0328) . Figure 3: Adult male of Tityus tayrona from Turbaco: a) entire dorsal view; b) entire ventral view. Remarks: all specimens recorded herein were obtained under different conditions, but always in arid to desert areas, just as for the types (Teruel & Roncallo, 2008a). The individuals from Irrujunai were all found packed together inside a tree hole, and the one from Rancherías river was found under a rock in a secondary dry forest, syntopically with Tarsoporosus macuira Teruel et Roncallo 2007 . The remaining specimens were all captured in places associated with human environments: inside crevices of benches and walls in schoolyards (three specimens from Riohacha), and inside inhabited houses (one each from El Pasito and Riohacha), syntopically with Centruroides margaritatus and T. macuira . The additional specimens now available allow to assess intraspecific variability in R. caribensis , and to update its diagnosis. For example, the specimens from Irrujunai are basically light orange-brown with the dark pattern less marked, and thus, the scorpions look essentially ferrugineus to unaided eye. Also, one female from Irrujunai is smaller ( 43 mm ), and the ones from Palomino and El Pasito are larger (52 and 55 mm , respectively) than those of the type series ( 48–50 mm ). On the other hand, the undetermined male from Zulia associated by Teruel & Roncallo (2008a: 8) to R. caribensis was re-examined and compared to the additional samples, and it was confirmed to belong to this species (see above, in New Records).
