ABSTRACT
Given the growing use of alternative sources of protein, studies on the commercial viability of amazonians wild species, based on the yield of their carcass, are still scarce in the literature. To evaluate yields of carcass and commercial cuts of caiman meat (Caiman crocodilus yacare), according to sex and weight categories, besides analyzing their revenue. Thirty animals in termination phase were selected, separated by sex and weighed. The cuts analyzed was of 59.7% in relation to total live weight, and of 70.7% in relation to the carcass. Regarding the yields of the cuts, the average weight difference in detriment to the sex of the animals was minimal, however, in the weight categories, animals classified as intermediate and heavy (5.9-9.1 kg) resulted in higher cut weights (p < 0.01) and consequently in revenue for most of the meat cuts (66.7%), especially for tail, back, and sirloin fillets. It can be concluded that the carcass yield of caiman is high, and that heavy animals resulted in higher yields of prime cuts, emphasizing the need to carry out studies that prioritize the cost/benefit ratio taking into account the age and weight of the animals.

Aplectana longa n. sp. (Ascaridida: Cosmocercidae) from the small intestine of Gastrotheca microdiscus (Amphibia: Hemiphractidae) is described and illustrated. The new species is characterized by the combination of a unique set of morphological characters: 1) Large body size in both sexes; 2) Lateral alae absent; 3) Gubernaculum present, small, thin, weakly sclerotized, pointed at the distal end and curved proximally at the end, with a small and punctiform papilla-like dilation, and 4) Caudal papillae arrangement (9+1:0:6). The distribution pattern of caudal papillae is similar only to Aplectana chamaeleonsis. Nevertheless, Aplectana longa n. sp. is easily differentiated from this species by the arrangement of precloacal papillae. This is the 57th species of the Aplectana and the 16th species reported from Brazil.

Parapharyngodon silvoi n. sp. (Nematoda: Pharyngodonidae) is described from the large and small intestine of the Muller's termite frog Dermatonotus muelleri (Boettger, 1885) from the biome Caatinga, Exu municipality, Pernambuco State, Brazil, Dermatonotus muelleri is a fossorial species with a specialized termite diet, and feeding and reproductive behavior occurring only during the wet season. The new species is distinguished from other species of the genus Parapharyngodon by showing ovary not coiled around the esophagus, morphology of anterior cloacal lip, spicule size and number of caudal papillae.
