We describe a new species of the genus Ninia from the Chocó-Magdalena biogeographic province, which was previously reported as a distinct population of N. maculata or as N. atrata from the western slopes of the Cordillera Occidental of Colombia. The new species is similar to N. atrata, N. celata, N. espinali, N. franciscoi, and N. maculata. It shares the following characteristics with the species mentioned above: 19 dorsal scale rows without reductions; dorsal ground color black or dark brown; white or cream occipital nuchal collar. However, it is easily distinguished from all other congeners because it has a non-regular color pattern in the ventral surfaces of the head and body, subcaudal surface homogeneously black or dark brown, two nasal scales, and one lateral projection ornamented with a large basal hook-shaped spine that is larger than any other spine on the hemipenial body. The presence of a lateral projection on the hemipenial body makes the new species the only member of the genus from South America that shares this feature with its Central American congeners. This feature suggests a closer relationship with this linage. Finally, our results indicate that proper and careful revision of the Ninia atrata species complex will help to understand and clarify the taxonomic composition of the genus.

Unknown Male

The genus Decidia Stål, 1875 is revised with an updated description of the genus, descriptions of all four known species, illustrations and keys are provided. The male of the type-species Decidia soranus (Westwood, 1859) is described and illustrated for the first time and a re-description of the females is given. Examination of the Colombian Peruphasma doylei (Caudell, 1906) has shown this to belong in Decidia (n. comb.); the male is re-described and the previously unknown female described and illustrated for the first time. Also Autolyca blapoides Redtenbacher, 1906 from South Ecuador has proven to belong in Decidia and is here transferred (n. comb.) with the female re-described and unknown male described and illustrated for the first time. These two species show the genus Decidia to contain not only winged but apterous species as well. A very colourful new species, Decidia magnifica n. sp. from the central Cordillera of Colombia, is described and illustrated from both sexes. The eggs of Decidia remain as yet unknown. Decidia appears to be restricted to the Andean regions of Central and Southern Colombia and Ecuador above an altitude of 2000 metres, referred to as the biogeographical province Cauca. The genus shows close relation to the Central American Autolyca Stål, 1875 and is hence re-transferred from Pseudophasmatini to the tribe Anisomorphini (rev. stat.).

A New Species

The Asian Temple Pitviper Tropidolaemus wagleri is a widespread polytypic species complex with a complicated taxonomic history, a lengthy species synonymy list, and a geographic distribution encompassing Vietnam, Thailand, Malaysia, Singapore, Brunei, portions of Indonesia, and the Philippines. As a prelude to a comprehensive review of this species complex, we describe a new species of Temple Pitviper based on five historic museum specimens from the Indonesian island of Sulawesi. The new species can be distinguished from sympatric members of the Tropidolaemus subannulatus complex and other congeners on the basis of its conspicuous color pattern and scalation characters. Available collecting data suggest that the new species has a wide distribution in rainforests and lower montane wet forests of Sulawesi Utara and Sulawesi Tengah provinces.

A New Species

Pseudancistrus reus is a new species from the Río Caroní (Río Orinoco drainage) of Venezuela known from two individuals. It differs from all other Pseudancistrus by having a color pattern consisting of alternating dark and light bars. In addition, it differs from all except P. genisetiger and P. papariae by having an incomplete mid-dorsal plate row and from P. genisetiger and P. papariae by having 18 contiguous mid-dorsal plates vs. 14 plates, a plateless break and then two more plates at the end of the caudal peduncle. The type locality of P. reus was submerged by the construction of the Caruachi dam, and is also the only known locality of the gymnotiform Sternarchorhynchus gnomus, making it imperative that the conservation status of these and other potential Caroní endemics be assessed. Pseudancistrus reus is the first species of Pseudancistrus sensu stricto from the Orinoco. Although the relationship of the species to other Pseudancistrus is unknown, P. reus may have gained access to the Orinoco either via stream capture between the Caroní and the Rio Uraricoera (Rio Branco – Rio Negro drainage) or via stream capture between the Caroní and either the Cuyuní or Mazaruni Rivers (Essequibo River drainage).key word: Siluriformes, Loricariidae, taxonomySe describe como especie nueva Pseudancistrus reus del río Caroní (cuenca del río Orinoco) en Venezuela, basada en dos ejemplares. Difiere de todas los demás Pseudancistrus en tener un patrón de pigmentación que consiste de barras claras alternando con oscuras. Además, difiere de todas los demás, menos P. genisetiger y P. papariae en tener la fila medio-dorsal de placas incompleta, y de P. genisetiger y P. papariae difiere en tener 18 placas medio-dorsales contiguas vs. 14 placas seguidas por una zona sin placas y luego dos placas más en el pedúnculo caudal). La localidad típica de P. reus fue sumergida por las aguas del embalse Caruachi. Ese sitio es también la localidad típica de Sternarchorhynchus gnomus, haciéndolo imprescindible evaluar el estado de conservación de estas dos especies más las otras endémicas del bajo Caroní. Pseudancistrus reus es la primera especies de Pseudancistrus sensu stricto de la cuenca del río Orinoco. Aunque desconocemos las relaciones con otras Pseudancistrus, P. reus puede haber ganado acceso al Caroní vía la captura de caños en las cabeceras del río Uraricoera-Branco-Negro o del río Cuyuní o Mazaruni, afluentes del río Essequibo.

A New Species

A new definition for the genus Moribaetis Waltz & McCafferty 1985 is given. Its type species, Moribaetis maculipennis (Flowers 1979) is redescribed based on male and female imagoes reared from larvae near the type locality in Panama. Larvae, formerly wrongly attributed to Moribaetis salvini (Eaton 1885), and a male imago, formerly wrongly attributed to Moribaetis macaferti Waltz 1985, belong to a new species Moribaetis latipennis sp. n., which is described here based on a male imago reared from larva in Panama. Both species, M. maculipennis and M. latipennis sp. n., are distinct from M. salvini, which is known as a single male imago (lectotype) from Costa Rica. All other species, formerly attributed to Moribaetis, are excluded from this genus; a new combination Caribaetis macaferti comb. n. is proposed for the species originally described as Moribaetis macaferti Waltz (in Waltz & McCafferty) 1985, and a new combination Baetis (Rhodobaetis) mimbresaurus comb. n. is proposed for the species originally described as Moribaetis mimbresaurus McCafferty 2007.
