DiagnosisDiagnosis. Hemiphyllodactylus goaensis sp. nov. can be diagnosed from congeners by the unique combination of snout-vent length up to 32.4 mm (n=3); five or six chin scales; postmentals not enlarged; 10–12 supralabials and 10 or 11 infralabials; 16–18 dorsal scales and 13 or 14 ventral scales at mid-body contained within one longitudinal eye diameter; four or five subdigital lamellae on the digit I of manus and pes; lamellar formula of manus 2222; la- mellar formula of pes 2323 and 2333; males with nine or ten precloacal pores separated by 1–5 poreless scales from a series of 10–12 femoral pores on each thigh (n=2); no plate-like enlarged subcaudals; head with dark postorbital streak and longitudinal markings on nape, dark postorbital streak more or less well-defined and may continue until hindlimb insertions, longitudinal markings on nape extending just past forelimb insertions; dorsal pattern of broken dark longitudinal markings and light and dark speckling; postsacral marking with light-coloured anteriorly project- ing arms indicated by broken streak extending anterior to hindlimb insertions; belly stippled with black (from Khandekar et al. 2021).

Comparison with peninsular Indian congeners. Hemiphyllodactylus goaensis sp. nov. can be distinguished from all other Indian congeners on the basis of the following differing or non-overlapping characters: males with nine or 10 precloacal and 10–12 femoral pores (versus males with eight or nine precloacal and two or three femoral pores in H. arakuensis, six or seven precloacal and 6–8 femoral pores in H. aurantiacus, nine or 10 precloacal and six or seven femoral pores in H. jnana, nine precloacal and eight femoral pores in H. kolliensis, nine or 10 precloa- cal and six or seven femoral pores in H. minimus, eight or nine precloacal and 7–9 femoral pores in H. nilgiriensis, and 11 precloacal and 11 femoral pores in H. peninsularis); males with 1–5 poreless scales between precloacal and femoral pores (versus 11–14 in H. arakuensis, 9–11 in H. aurantiacus, 10–12 in H. jnana, and 7–9 in H. nilgirien- sis); 16–18 mid-body dorsal scales in one eye diameter (versus 13–16 in H. arakuensis and H. aurantiacus, and 20 in H. peninsularis); 13 or 14 mid-body ventral scales in one eye diameter (versus 9–13 in H. aurantiacus, 10–13 in H. kolliensis, and eight or nine in H. minimus); lamellar formula of pes 2323 and 2333 (versus 2333 or 3333 in H. arakuensis; 2233, 2333 and 3333 in H. aurantiacus; 2222 in H. jnana, H. kolliensis, H. nilgiriensis and H. peninsu- laris; 2332 or 2333 in H. minimus) (from Khandekar et al. 2021).
