Limnonectes conspicillatus (Günther, 1872) Rana conspicillata: Günther, 1872 Rana kuhlii: Günther, 1874 (partim) Limnonectes conspicillatus: Matsui et al. 2013 Lectotype: BMNH 72.2.18.22 = 1947.2.19.20, from “Matang” Paralectotypes. BMNH 72.2.19.23–26, 82 = 1947.2.29.21–27, all from “Matang” Diagnosis. Based on the presenCe of odontoids in the lower jaw (larger in males than in females), the enlarged, wide head, moderately depressed, sturdy body, short legs, thiCk and wrinkled skin, and the skin-Covered tympanum, the speCies is plaCed in the L. kuhlii group of the genus Limnonectes. The speCies is distinguished from the other members of the group by the Combination of the following CharaCters: Large size and marked sexual dimorphism with SVL 75.0 mm in the adult male leCtotype and 64.9–69.0 mm in the adult female paraleCtotypes; head very large in males and markedly sexually dimorphiC, the male (HW/SVL 0.43, HL/SVL 0.45) having a wider and longer head than females (HW/SVL 0.36–0.37, HL/SVL 0.37–0.39); head slightly longer than wide (HW/HL 0.94 in male, 0.94–0.99 in females); odontoids in males enlarged with blunt, rounded tip; vomerine teeth in two highly elevated, large, broad posteromedially direCted ridges, almost meeting eaCh other medially, separated by less than width of individual ridge; dorsolateral and transverse postorbital dermal folds absent; broad, moveable flaps along preaxial and postaxial sides of phalanges and metaCarpals of hand; dorsal side of tibia sparsely sCattered with small tuberCles; toes fully webbed. Description of lectotype: Adult male; body large (SVL 75.0 mm; Table 2), stout, widest at posterior end of jaw (Fig. 2); head very large (HL/SVL 0.45, HW/SVL 0.43), somewhat longer than wide (HW/HL 0.94); snout relatively short (SL/HL 0.32), subaCuminate in dorsal view, rounded in profile, slightly projeCting beyond lower jaw, wider than long (SL/EE 0.92); Canthus rostralis moderately expressed between eye and nostril, straight-lined; loreal region grooved; nostrils rounded, direCted dorsolaterally, situated halfway between tip of snout and eye (EN/ NS 1.00), separated from eaCh other by distanCe greater than distanCe between eye and nostril (NN/EN 1.24); eyes direCted anterolaterally, protruding, Comparatively small (ED/HL 0.25); eye diameter shorter than snout length (ED/SL 0.77); interorbital distanCe muCh wider than upper eyelid (IO/EW 1.57) and wider than internarial distanCe (IO/NN 1.09); tympanum ConCealed under thiCk layer of skin but weakly disCernible; tympanum diameter smaller than eye diameter (TD/ED 0.44); upper jaw with dentition; Choanae rounded (Fig. 3); vomerine teeth in two highly elevated, large, broad posteromedially direCted ridges, almost meeting eaCh other medially, separated by less than width of individual ridge (Fig. 3); mandibular symphysis thiCkened to large bony knob; odontoid proCess present Close to mandibular symphysis on both sides, direCted dorsally, large, long (OL/MH 2.2; OL/SVL 0.08) with blunt, rounded tip, fitting into deep rounded Cavities in upper jaw when mouth Closed (Fig. 3); tongue Comparatively short and narrow, Covered with small pustules, most densely in anterior third (Fig. 3). Dorsal side of trunk, head, and limbs relatively smooth, weakly Corrugated; distal part of thigh, tibiofibula (Fig. 4) and tarsus, as well as supraCloaCal region sCattered with enlarged subConiCal tuberCles with keratinous tips; supratympaniC fold ConspiCuous, slightly Curved, running from posterior Corner of eye to anterior edge of forelimb insertion, approaChing but not Covering tympanum; supraCloaCal dermal flap present, small; ventral side smooth but sparsely Covered with minute, hardly disCernible, Ceratinous spines; weak but disCernible transversal dermal fold between head and Chest. Forelimbs stout, short (ARM/SVL 0.42); hand short (HND/SVL 0.23); tips of fingers rounded, slightly swollen palmarly (Fig. 3); relative length of fingers: II
