The two species differ in relative lengths of the fingers, skin texture, coloration, and advertisement call. Although the new species has an elevational range of2000-3300 m, it is most abundant at 2400-2800 m. A phylogenetic analysis of a previously defined clade of Gastrotheca based on a fragment of 16S mitochondrial gene provides strong support that the sister taxon to the new species is G. atympana, a species from farther north in the Cordillera Oriental in Peru.
查看更多>>摘要：A large new species of Callulina is described from a series of 22 specimens from the montane and upper montane forest of the Nguru Mountains, Tanzania. The most striking features of Callulina meteora sp. nov. are the massive and boldly coloured glandson the arms and legs and a metallic sheen to the skin. The new species is distinguished further on the basis of acoustic and molecular data. The position, size and conspicuousness of the enlarged glands in the new species are strikingly similar to thoseof Nectophrynoides viviparus, a toad found also in the Eastern Arc Mountains of Tanzania. The new species is known from a single forest reserve and is of high conservation concern.
查看更多>>摘要：Odontosyllis pentalineata, a new species from California is described. It differs from all other Odontosyllis species in the following characters: colour pattern consisting of five longitudinal black bands along body at median, dorso-lateral and lateral sides, a long pharynx with five large teeth directed backwards, and compound chaetae with short bidentate blades, slightly spinulated. Sequence data from COI are provided for molecular characterization. Additionally, the type species of O. Uniata Hartmann-Schroder, 1962 and O. gymnocephala Hartmann-Schroder, 1965 are re-described based on type material.
查看更多>>摘要：Cassidulus infidus Mortensen 1948b is one of the few recent species of the family Cassidulidae Agassiz & Desor 1847 and known only from its poorly described holotype. In Brazil, this family is represented only by two extant species and, to date, bothare endemic to Bahia (C. infidus) and Rio de Janeiro {Cassidulus mitis Krau 1954). After a century of its first capture, some topotypes of C. infidus were found enabling its redescription, which are provided herein. The characterization of some of its ecological aspects and a key to the known species of Cassidulus are also given.
查看更多>>摘要：A survey of the parasites associated with the nesting freshwater turtles Podocnemis lewyana and Trachemys callirostris callirostris revealed the presence of seven Digenea species. Pseudonematophila n. gen. is described from the stomach of P. lewyana.The new genus is distinguished from other Schizamphistominae because it possesses a genital sucker and numerous tegumental papillae from the posterior level of the genital sucker to the posterior end of the body, which had not been described before for this subfamily. Nematophila ovalis Cordero & Vogelsang, 1940 is transferred to Pseudonematophila n. gen. as P. ovalis n. gen. n. comb, based on morphological characteristics. The genus Nematophila Travassos, 1934 is emended by the inclusion of Allassostoma venezuelensis andParamphistomum argentinum described by Cordero & Vogelsang in 1940. Both species are redescribed based on Colombian specimens, and the first key for the genus is provided. Telorchis hagmanni Lent & Freitas, 1937 is redescribed from Colombian specimens, and Telorchis corti, Heronimus mollis and Neodeuterobaris pritchadae are reported. Prevalence, meanrtntensity, and mean abundance values are estimated for all species. Host feeding habits and behavior are considered the main factors determining the taxonomic composition founded in these turtles species.

Collected at 73 m, Apogonichthyoides erdmanni has very distinctive markings on the head and body. It is brown with a dark spoton the body below the anterior lateral line, two slightly darker body bars and darker markings on the head, all similar features to those of the Philippine species Apogonichthyoides uninotatus. The new species has vivid, horizontal dark cheek and post-ocular marks, a small oval spot between the eye and tip of upper preopercular arm, yellowish anal, second dorsal and caudal fins, a narrow basicaudal bar less than 1/3 the length of the caudal peduncle, a vertical bar under the posterior half of the second dorsal-fin base reaching the base of the anal fin, small dark spots on the lower half of the body onto the lower portion of the caudal peduncle and a body spot smaller than the pupil of the eye. Apogonichthyoides uninotatus has a faint diagonal cheek mark, a faint horizontal post-ocular mark, a faint dash between the eye and the tip of the upper preopercular arm, brownish anal, second dorsal and caudal fins, a broad basicaudal bar more than 2/3 the length of the caudal peduncle, a broad body bar as achevron including all of the second dorsal-fin base reaching the base of the anal fin, no small dark spots on the lower half of body and a body spot larger than the pupil of the eye. A key to twenty-two species of Apogonichthyoides is provided.
