Pseudogonatodes furvus is an endemic gecko from the region of the Sierra Nevada de Santa Marta, an isolated massif located in the continental Caribbean region of Colombia. Pseudogonatodes furvus is the type species of the genus, and its morphology and natural history remain poorly known. This lizard was described based on two specimens. After its description, the species has only been mentioned in a handful of taxonomic studies of Pseudogonatodes, in which a few morphological characters of P. furvus have been mentioned. One other paper reported two new localities, without providing new information on the external morphology, especially the lepidosis of the newly obtained specimens. Here we review the external morphology of P. furvus, based on examination of the holotype and six additional specimens. We provide an extended diagnosis and definition, description of holotype, variation, comparisons with other Pseudogonatodes, geographic distribution (adding a fourth locality to the known distribution for the species), and conservation status. Additionally, we describe osteological features for the diagnosis of the genus.

Geographic distribution and habitat use of Lepidoblepharis miyatai (Squamata: Sphaerodactylidae), with comments on the taxonomic status of the genus in northern Colombia. We present some ecological and biogeographic data on Lepidoblepharis miyatai, a small and endangered gecko endemic to the northwestern foothills of the Sierra Nevada de Santa Marta (SNSM), 31 years after its description. Based on museum specimens and feld observations, we recorded four new localities with confrmed presence of L. miyatai. We calculated the extent of occurrence and altitudinal distribution of this species reaching 21.3 km2 and from sea level to 360 m respectively. Lepidoblepharis miyatai inhabits plant formations of scrub thorn and tropical deciduous forest. Based on microhabitat data obtained from 88 individuals observed in “Las Tinajas Village” we can state a differential use of three substrates with predominant use of leaf-litter. We consider L. miyatai an endemic species of the northwestern sector of the SNSM with a distribution range limited to the south-west by the occurrence of L. sanctaemartae, and towards the east by a thus far undetermined Lepidoblepharis species (here called Lepidoblepharis cf. sanctaemartae). We do not register sympatry of L. miyatai with any other congener. Accordingly, we consider that the recent records of this species in the southeast sector of SNSM are erroneous, given that the specimens cited as L. miyatai of this zone correspond to Lepidoblepharis cf. sanctaemartae. Finally, a reevaluation of the conservation status of L. miyatai is needed, including precise information of its distribution.

We describe new findings on the geographic distribution, habitat uses, relative abundance, tadpoles, and advertisement call of Allobates ignotus . Data of habitat uses and relative abundance were collected during five annual fieldtrips of seven days each one, from April 2010 to June 2014, in a mining zone of Canime Creek Basin, La Jagua de Ibirico, Cesar Department, northeast Colombia. Tadpoles and advertisement call were obtained in La Veguita Creek Basin, Manaure Balcon del Cesar, Cesar. We report six new localities with presence of A. ignotus , all between 7-96 km in straight line to the type locality, from 194-1236 m a.s.l. This species is recorded for the first time in the Tropical Dry Forest Life Zone and in La Guajira Department. Four substrate categories used by A. ignotus were detected (leaf-litter, rocks, naked floor, and lower branches), and differential use was highlighted. The larval morphology of A. ignotus was described, based on 11 specimens between 25-29 stages. Like other Allobates tadpoles, the gap of the second teeth row is “wide”. The advertisement call of A. ignotus is composed by a series of high frequency ascending pulsed notes. Possibly, the high frequency of the call is due to the acoustic disturbance generated by the streamflow noise of the creeks. In 2014, a decrease of relative abundance of A. ignotus in Canime Creek was detected. This, coupled to restricted distribution and loss of habitat quality are sufficient criteria to suggest the category of vulnerable for A. ignotus .
