|Distribution||Philippines (Panay, Luzon)|
Type locality: Western foothills of Mt. Madja-as (11°23’N, 122°09’ E, elev. 1500 m), Barangay Allojipan, Municipality of Culasi, Antique Province, Panay Island, Philippines.
|Types||Holotype: PNM 2712|
|Diagnosis||Diagnosis: Elongate loreal (= Iori-ocular) present, extending from the posterior border of the nasal to the orbit of the eye; ventrals (M) 139-146; subcaudals (M) 36-39; total of ventrals plus subcaudals (M) 175-185; scales of dorsum each edged with a mottling of brown pigment, the posterior and central portions of each scale pale, lacking a dense infusion of dark pigment, the lateral and latero-ventral scales with larger pale areas than those on the dorsum; no distinct nuchal collar but pattern of pale centers and dark rims characterizes nuchal scales and head shields, which are somewhat mottled dark and light. Pseudorabdion talonuran belongs to the section of the genus Pseudorabdion characterized by the presence of a loreal (lori-ocular) shield. From the allied Philippine P. mcnamarae, it differs in lacking a pale nuchal color in adults and in having more than 30 subcaudals in both males and females; from P. taylori it differs in having the centers and apical tips of the dorsal scales nearly pigmentless whereas in P. taylori the centers are pale brown, and in having the hemipenes minutely spinose (in P. taylori the apical tips are calyculate). Among the non-Philippine species having a lori-ocular, P. talonuran differs from P. sarasinorum in having the anterior chin shields in contact with the mental, from P. albonuchalis in having fewer subcaudals (36-39 vs. 43) and the frontal not border the eye, and from P. saravacensis in having a greater number of subcaudals (36-39 vs. fewer than 30) and fewer maxillary teeth (8 vs. 14). From the remaining species in the genus, it differs in having an elongate loreal (lori-ocular) shield that borders the eye (Brown et al. 1999).|
|Etymology||Named after the words “talon” (= forest) and “uran” (= rain) in the Philippine dialect Caray-a, in reference to the high elevation rain forest habitat where the new species was collected on Mt. Madja-as.|
