DIAGNOSIS. Total length 25–52 mm. Dentate margin of pedipalp chela movable finger with distinct granules divided into 10 linear rows, apical rows of 3 granules, and 3 terminal granules. Tergites and carapace smooth to finely granular (more so in males). Median eyes located anteriorly in the ratio ca 1:2.5. Metasomal segments III– IV with well developed dorsolateral carinae. Dorsal surface of metasomal segments mesially granulated. Metasomal segments I–V granulated. Pectinal teeth number 14–17 in both sexes. Telson without subaculear tooth.
HEMISPERMATOPHORE (Figs. 30–33, 47). Trunk and capsule region very narrow, elongate (Fig. 47). Flagellum cylindriform, short, pars recta with broad base; pars reflecta thickened, about the same length as capsule region. Median lobe narrow with prominent, curved dorsal carina. Basal lobe strongly developed as a prominent, blunt, rounded scoop arising dorsally from base of median lobe carina. External surface of capsule region roughly sculptured with series of transverse corrugations.
COMMENTS. Buthoscorpio sarasinorum is probably endemic to Sri Lanka. Tikader & Bastawade (1983: 158– 163, figs. 430–452) and Thulsi Rao et al. (2005: 7) cited B. sarasinorum from India but according to the characters they cited, their records probably represent a different species. Aswathi et al. (2015: 218) cited B. sarasinorum only from Sri Lanka (Aswathi et al., 2015: 217, fig. 1) but in their table (Aswathi et al., 2015: 218, tab. 2) they listed variable or incorrect diagnostic characters for B. sarasinorum.
