| Distribution | Costa Rica, Panama Type locality: Finca Las Cruces, near San Vito de Java, 4 km S San Vito, 1,200 m elevation, Puntarenas Province, Costa Rica |
| Reproduction | oviparous (not imputed, fide Zimin et al. 2022) |
| Types | Holotype: LACM 148599, an adult male. Collected in September 1972 by James E. DeWeese and Ron T. Harris. Figs. 2C, 12, 14B in Cadle 2012. |
| Diagnosis | Diagnosis: Dendrophidion crybelum is characterized by (1) dorsocaudal reduction from 8 to 6 occurring posterior to subcaudal 40 (range, 42–58); (2) single anal plate; (3) low subcaudal counts (<120 in males and females); (4) black-edged pale crossbands on the neck nearly always more than one scale row wide; (5) pale crossbands continuing to the vent but posteriorly tending to become invested with dark pigment, forming a lateral and vertebral series of ocelli within dark bands; (6) in adults, a tendency for small dark spots and flecks on subcaudals and posterior ventrals; (7) a relatively long cylindrical hemipenis with a large number of spines (>70) and a short, nonbulbous apex ornamented with freestanding membranous ridges. The combination of few subcaudals and a single anal plate will distinguish D. crybelum from all other species of Dendrophidion except D. vinitor, D. apharocybe, and D. paucicarinatum. (CADLE 2012: 210) |
| Comment | Distribution: not known from Panama with certainty, but the closest locality in Costa Rica is only ~1 km away from the Panamanian border, hence most likely in Panama too (S. Lotzkat, pers. comm., 23 Dec 2015). Habitat: partly arboreal (Harrington et al. 2018). |
| Etymology | The species name is derived from the Greek adjective krybelos meaning ‘‘hidden’’ or ‘‘secret.’’ Transliteration to Latin yields crybelum (with neuter gender ending to agree with the neuter generic name). It recognizes the cryptic nature of this species and the fact that it remained unrecognized for so long in a well-studied herpetofauna. |
