A previous paper has described some of the tanaidomorph species found. Records of apseudomorph species from deep-sea chemosynthetic habitats are almost non-existent. The present study reports on seven apseudomorph species from five different genera from this material; two of the species, one in each of the genera Sphyrapus and Pseudosphyrapus are new to science, although there was insufficient material available to describe fully the Pseudosphyrapus species. Two of the other species are reported herein for only the second time. A neo-type is erected for Apseudes setiferus Bacescu, and a lectotype for Sphyrapus malleolus Norman & Stebbing; these two, plus Atlantapseudes nigrifrons Bacescu and Fageapseudes retusifrons Richardson are redescribed. The habitus of Apseudes grossimanus is figured. None of the taxa appear to show any morphological features specifically adapted to the peculiar habitat around mud-volcanoes. The genus Collossella is relegated to the synonymy of Fageapseudes. The non-chemosynthetic-habitat-associated species Apseudes coriolis is moved to Taraxapseudes

The new species is the first dendrobatid reported from this mountain range, though many other congeners are known from theCordillera de Merida, also in the Venezuelan Andes. It can be readily distinguished from all congeners by the unique combination of the following characters: dorsal skin granulate, paired and protuberant dorsal digital scutes, finger I shorter than finger II, fringes absent on fingers I and IV, present and conspicuous on all toes, toe webbing basal, dorsolateral stripe present, oblique lateral stripe diffuse, ventrolateral stripe absent. With this new species the number of Aromobates species from Venezuela increases to 13.

Recent molecular investigations transferred the species to genus Pseudohynobius and presence of the internasal bone was shown to be a variable character. Taxonomically this species is relatively poorly known with no descriptions of egg, larvae, habitat, and other biological data. Furthermore, the extent of adult variation is unknown. We describe features of the adult, larvae, egg sacs, karyotype, breeding habitat and habits. The species is characterized by the following features: dorsal color gray-yellow with yellowish spots; dorsal tail with distinct yellowish line; total length shortest in the genus; tail length shorter than snout-vent length; head length to head width ratio smaller than 1.53; and a moderate number of vomerine teeth (11-15). The karyotype and the breeding season of Ps. puxiongensis are similar to that of other species of the genus.

(male, Panama), E. triste sp. nov. (male, Venezuela), E. caricoi sp. nov. (male, Colombia), E. venezuelana sp. nov. (female, Venezuela), E. silvae sp. nov. (female, Peru), E. frijoles sp. nov. (female, Panama) and E. zurqui sp. nov. (female, Costa Rica). A new record of Enna estebanensis (Simon, 1898) is reported from Ecuador.
