|Distribution||Philippines (Lubang, Luzon, Mindoro, Polillo)|
alcalai: Negros, Cebu, Panay; type locality: ridge on the north side of the Maite River, 5 km west of Valencia.
|Types||Holotype: ZMUC 60489|
Holotype: CAS 101587 [alcalai]
|Diagnosis||Diagnosis (Cyclocorinae): Members of the Philippine endemic subfamily Cyclocorinae can be distinguished from many members of the Elapoidea by possession of (1) intermediate body size (250–600 mm total length, excepting the unnamed lineage represented here by the specimen KU 337269); (2) 15 or 17 smooth scale rows at midbody; (3) a single row of subcaudals (shared by members of the genera Cyclocorus, Hologerrhum, and the unnamed lineage represented by KU 337269); (4) a distinctively elongate snout, characterized by the presence of enlarged anterior chin shields and an elongate loreal scale (shared by members of Oxyrhabdium and Myersophis); (5) a small number (5–6) of supralabials (Oxyrhabdium, Myersophis, and the unnamed lineage represented by KU 337269); and (6) markedly bulging, dorsally protruding eyes (Oxyrhabdium and Myersophis).|
Definition (genus): maxillary teeth 16 to 21, the anterior three to seven increasing in size posteriorly, the last two very large and fanglike, followed by a short diastema and 12 to 15 small teeth; maxillary bone bent inwards anteriorly; head slightly distinct from neck; eye small, pupil round ; body cylindrical; scales in 17 longitudinal rows at midbody, smooth, without apical pits; ventrals rounded ; subcaudals unpaired ; hypapophyses present throughout dorsal vertebrae; hemipenes elongate, narrow, un- forked; sulcus spermaticus unforked (from LEVITON 1967).
Diagnosis (lineatus): Usually two anterior temporals; eight upper labials, three of which border eye; ventrals: males 142 to 157, females 146 to 163; subcaudals: males 52 to 59, females 42 to 48; tail length/standard length ratio: males 0.337 [0.295 to 0.371], females 0.226 [0.196 to 0.262]; white spots present on lateral edge of ventrals; venter with many dark usually triangularly-shaped blotches.
Diagnosis (alcalai): Usually two anterior temporals; eight upper labials, three of which border eye; ventrals: males 142 to 153, females 144 to 159; subcaudals : males 42 to 53, females 33 to 44; tail length/ standard length ratio : males 0.259 [0.235 to 0.296], females 0.197 [0.152 to 0.223]; very small white spots present on outer lateral edges of ventrals ; venter with dark, triangularly-shaped blotches, especially well developed along lateral edges of ventral shields.
|Comment||Type species: Lycodon lineatus REINHARDT 1843 is the type species of the genus Cyclocorus DUMÉRIL et al. 1854.|
Type genus: Cyclocorus DUMÉRIL 1853: 460 is the type genus of the subfamily Cyclocorinae Weinell & Brown 2017.
Phylogenetic definition (Cyclocorinae): Cyclocorinae refers to the clade originating in the last common ancestor of Oxyrhabdium leporinum (Günther, 1858), Cyclocorus lineatus (Reinhardt, 1843), the unnamed lineage represented by KU 337269, and all species that descend from that ancestor. It can also be conceived of as the largest crown-clade containing members of the genera Cyclocorus, Hologerrhum, Myersophis, and Oxyrhabdium, and members of the unnamed lineage represented by KU 337269.
Distribution: see map in LEVITON 1967.
