|Distribution||India (Tamil Nadu)|
Type locality: Chitteri (= Sitteri), a hill range located near Dharmapuri, in Southern Eastern Ghats.
|Types||Holotype: ZSI 22393|
|Diagnosis||Description: A small and short-bodied skink, with tiny pentadactyle limbs, short and supple trunk and a fairly robust tail. Head slightly wider than neck, neck not evi- dent; trunk short thick and wide; anteriorly adpressed forelimb reaches tympanum; adpressed ipsilateral limbs bent inwards along trunk fail to contact each other by slightly more than one head length; regenerated tail shorter than rest of body (Ganesh & Aengals 2019).|
Comparisons: Here L. pruthi is compared with peninsu- lar Indian congeners: L. punctatum, L. albopunctatum (whole of the region), L. guentheri (Western Ghats, East- ern Ghats), L. lineatum (Western Ghats, Coromandel Coast?), L. vosmaeri (Eastern Ghats, Deccan plateau). Lygosoma pruthi can be diagnosed by its higher midbody scale row counts 32-34 (vs. < 28 in all other regional congeners); lower eyelid with a transparent disc (vs. scaly in L. albopunctatum); both manus and pes with 5 digits (vs. 4 digits in manus and / or pes in L. lineatum, L. vosmaeri); proportionally shorter axilla-groin distance 1.2-1.3 times snout-shoulder distance (vs. longer in all other regional congeners); frontal scale subequal to com- bined lengths of frontoparietal and interparietal (vs. frontal distinctly longer in L. punctatum); frontoparietals divided (vs. single in L. vosmaeri, L. lineatum); dorsum with feeble linear series of black dots (vs. a pair of dorso- lateral yellow stripes and bold black spots in L. puncta- tum; pair of obscure dorsolateral yellow stripes in L. guentheri; a distinct series of dorsal stripes in L. linea- tum); lateral body with a dark brownish wash (vs. lateral body without such a colouration in L. punctatum, L. line- atum; with dense patches of white spots in L. albopuncta- tum); tail colour in subadults dull slaty blue (vs. orange red in L. punctatum, L. vosmaeri, L. guentheri; brown in L. albopunctatum, L. vosmaeri) (Ganesh & Aengals 2019).
|Etymology||Named after its collector Dr. Hem Singh Pruthi (1897-1969) an eminent entomologist from the erstwhile ‘Punjab’ (Lal, 1954; Beolens et al., 2011)|
