The genus Freziera Willd. is distributed in Venezuela along major mountain systems, including Los Andes, Coastal Cordillera, and Guayana Shield. Two out of 11 Freziera species known from Venezuela are endemic to this country and could be endangered, but their actual conservation status is unknown, being Data Deficient according to the criteria of the IUCN. In this work, a key for the Venezuelan species is provided for the first time, and Freziera polita A.L.Weitzman ex J.R. Grande, sp. nov., from Cordillera de Mérida, is described and illustrated. Diagnostic characters of the new species, which is most closely similar to F. Guaramacalana D.Santam. & Cuello, include elongated petioles, subglabrous mature leaves, and corollas (at anthesis) that are exerted less than half the length of sepals.

As a part of an ongoing review for the genus Ternstroemia in the Guayana Shield, in northern South America, T. tepuiensis J.R.Grande, sp. nov. is described as new to science. This species, characterized by its relatively large leaves, flowers and fruits, as well as by its circumscissile dehiscent fruits, is only known from the sandstone tabletop mountains commonly named as «tepuis», where it seems to be a rather common floristic element. Ecological and biogeographical notes are included, while the conservation status of the new species is assessed as LC —Least Concern, following the IUCN Red List Categories—. A key to separate this species from remaining members of the genus that bear fruits with circumscissile dehiscence is offered at the end of the paper.

In this study, Fritillaria arsusiana (Liliaceae) is described and illustrated as a new species from Hatay province in southern Anatolia, Turkey. It is related to F. amana and F. hermonis by habitus features and broadly campanulate flowers, but differs mainly by its bulb shape and size, smaller leaf and flower features, and flower colour. It has also been morphologically compared with F. wendelboi, F. pinardii, and F. latakiensis. The detailed description, diagnostic characters, original photographs, geographical distribution, habitat and phenology, etymology, conservation status, and identification key of the new and the related species are presented in this study. IUCN conservation status of F. arsusiana is suggested as Critically Endangered (CR).

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.

ABSTRACT The rare Amazonian snake Eutrachelophis papilio is known from only five individuals, from four localities, belonging to its type-series, the more recent collected over 10 years ago. Here, we expand its distribution and describe its color in life for the first time. We also provide an estimate of its distribution area using the minimum convex polygon method and identify the values of anthropic pressure within its known distribution range with the Human Footprint Index. The new occurrence is located 291 km from the nearest known locality and its distribution is associated with pristine forests. Considering its rarity, and the absence of demographic and biological data, we suggest that the species should be classified as Data Deficient by IUCN criteria.

The genus Ludioctenus Fairmaire, 1893 hitherto included only L. cyprius (Baudi di Selve, 1871) from the eastern Mediterranean and L. pakistanicus Schimmel & Tarnawski, 2012 from Pakistan. Here, we describe L. afghanicus sp. nov. from the Nuristan Province in eastern Afghanistan. The distribution and morphological diversity of Ludioctenus is discussed, main diagnostic characters for all species are figured, and an identification key to the species of this genus is provided. Female pregenital segments and genitalia are figured for the first time for Ludioctenus, and the systematic position of this genus and its relatives is discussed.

Leuctra adjariae sp. n. and Leuctra georgiae sp. n. (Plecoptera: Leuctridae) are described as two new apterous stonefly species from the Meskheti Range (Lesser Caucasus) in southwestern Georgia. Descriptions and illustrations are provided for both sexes and diagnostic characters are discussed. Males and females of the two species are associated by DNA barcodes. Comparisons with corresponding regions of COI between L. adjariae sp. n. and L. georgiae sp. n. produced K2P genetic distances of 8.38%, values well associated with interspecific variation. The well-supported monophyly as well as results of an ABGD analysis confirms the validity of both new species. Capnioneura gouanerae Vinçon & Sivec, 2011, previously described and known only from Turkey, is reported for the first time for the Caucasus.
