DistributionIndonesia (Wetar Island)

Type locality: “Uhak, north coast of Wetar, Dutch East Indies.”  
Reproductionoviparous 
TypesHolotype: AMNH 32263, female; paratype: AMNH 32264 
DiagnosisDiagnosis: This form may be distinguished from the most closely related subspecies, Liasis mackloti mackloti (Duméril and Bibron) of Timor and Samao, by the larger number of scale rows (61-63 instead of 49-55) and the unpitted rostral shield.
Description: Female. Squamation: scale rows 48-63-31; ventrals 304; caudals cannot be counted as the tail is injured; supralabials 12 on the right side, with the sixth and seventh entering the eye, 11 on the left, with the fifth and sixth entering the eye; infralabials 18; preoculars 1; postoculars 2; supralabials 1-2 faintly pitted; infralabials 10-14 deeply pitted; rostral unpitted; 2 loreals on each side. Anal spurs present. Dentition: premaxillary teeth 2; mandibular teeth 22; maxillary 20; palatine 6; pterygoid 13.
Coloration: dorsum brownish gray with irregularly scattered black scales; sides paler but with black scales more frequent and merging into irregular black spots; belly grayish, speckled with black, and with large black spots at the sides.
Variation:-The paratype differs from the type as follows: scale rows 48-61-32; ventrals 301; supralabials on both sides 12, with fifth and sixth entering the eye; infralabials 17, with 9-13 pitted; 1 loreal; maxillary teeth 22; palatine 7; pterygoid 16. Another new subspecies of the genus Liasis is Australian. and is named for the type locality. (Stull 1932)
