|Distribution||Thailand, Vietnam, Cambodia|
Type locality: Thailand, Nakhon Ratchasima Province, Amphoe Pak Thong Chai, Sakaerat, 14°30'N, 101°55' E
|Types||Holotype: FMNH 181825, paratypes: ROM|
|Diagnosis||Diagnosis. Ptychozoon trinotaterra differs from all known species of Ptychozoon except P interme dium by the presence of three dark transverse bands in the axilla-groin region (vs four in remaining species). The new species differs from P. intermedium and further from P horsfieldiiby the presence of an enlarged (vs reduced) tail terminus, lateral (vs more caudal) orientation of the denticulate lobes of the tail, and the arrangement of preanofemoral pore-bearing scales in a continuous series (vs preanals and femorals separated). Ptychozoon trinotaterra differs from P lionotum in having a smaller maximum body size (Table 1), 15-16 (vs 18-23) denticulate tail lobes, reduced lobe fusion at the proximal border of the straight-edged tail terminus (vs crenulate tail terminus composed of 3-9 denticulate lobes fused at the proximal border), and absence (vs presence) of a predigital notch in the preantebrachial cutaneous expansion. Ptychozoon trinotaterra differs from P kuhli in having a smaller maximum body size (Table 1), limited terminal tail flap expansion (vs lateral expansion of the terminal flap well beyond the nearest denticulate lobe), and the absence (vs presence) of paravertebral tubercle rows. The new species is distinguished from P rhaco phorus by its larger body size, absence (vs presence) of highly spinose dorsal tubercles, presence (vs absence) of a terminal tail flap, presence (vs absence) of a lateral infraauricular cutaneous expansion, and presence (vs absence) of enlarged, imbricate membrane support scales on limb and midbody cutaneous expansions. Table 1 summarizes the distribution of diagnostic characters within the genus Ptychozoon and the Comparisons section provides more extensive comparisons between the new species and individual congeners (Brown 1999).|
|Etymology||Named after the three transverse dark bands in the axill-groin region (Latin “tri-” and “nota”). This species is the only known Ptychozoon from the Asian mainland ("terra").|
