A new species of Kohleria (Gesneriaceae) from Southwestern Colombia

A new species of Kohleria (Gesneriaceae) is described from the Colombian Andes, in the departments of Huila and Cauca. The new species, Kohleria huilensis, has long been documented from the Merenberg Natural Reserve (La Plata, Huila), but has been confused with K. inaequalis var. inaequalis and K. inaequalis var. ocellata. The new species is distinguished by the following characters: white sericeous and sparse villous indumenta on vegetative structures; calyx lobes elongate with revolute margins; corolla magenta to fuchsia, ventral lobe orbicular with apex truncate; filaments hirsute with glandular trichomes distally; and staminodes < 2.8 mm long.

Leptoscyphus revolutus (Marchantiophyta, Lophocoleaceae) sp. nov. from Ecuador Notes on the Bryophytes of Ecuador III

Leptoscyphus Mitten (1851: 358), a medium-sized genus of the Lophocoleaceae, is mainly distributed in tropical and temperate South America, Africa and Australasia, and is generally characterized by the brownish gametophyte colour and a laterally compressed perianth with a more or less bilabiate mouth due to the reduction of the ventral lobe (Vanderpoorten et al. 2010). 15 species are reported to occur in Ecuador (Gradstein & Benitez 2017). During revision of recent collections in the National Herbarium of Ecuador (QCNE) an undescribed species came to our attention which we here describe and illustrate.

Paraonis fulgens (Annelida: Paraonidae), a new record for the marine fauna of Turkey

This paper deals with the occurrence of Paraonis fulgens on the coast of Turkey. Three specimens of this species were found at 4 m on sandy mud bottom in İskenderun Bay, north-east Levantine Sea. The morphological and distributional features of the species were explained. The present study described a ventral lobe on chaetigers in the family Paraonidae for the first time.

A new genus and species of catshark (Carcharhiniformes: Scyliorhinidae) from eastern Indonesia

A new genus and species of catshark is described based on a single specimen collected off Ambon in the Maluku Islands of eastern Indonesia. Akheilos suwartanai belongs to the subfamily Schroederichthyinae which differs from the other catsharks in a combination of: similar sized dorsal fins, supraorbital crests present, pseudosiphon present on claspers, broad subocular ridges under eyes, posterior nasal flaps present, tips of rostral cartilage fused into a rostral node. It represents the first record of this subfamily outside of the Americas. Akheilos differs from the other genus in the subfamily, Schroederichthys in a combination of: clasper groove not fused dorsally, ventral lobe of caudal fin produced, more intestinal valve turns, anal fin slightly larger than second dorsal fin, and in colour pattern.

Two new species of Gyrodactylus von Nordmann, 1832 (Monogenoidea: Gyrodactylidae) parasitizing introduced poeciliids in Patagonia

Gyrodactylus superbus (Szidat, 1973) Popazoglo & Boeger, 2000 was described from Corydoras paleatus (Jenyns) (Callichthyidae) and represents the only known viviparous gyrodactylid reported from the Parano-Platense basin of Argentina. We describe two new species of viviparous neotropical gyrodactylids parasitizing the introduced poeciliid, Cnesterodon decemmaculatus (Jenyns, 1842) (Poeciliidae), from southern Argentina: Gyrodactylus decemmaculati n. sp. and Gyrodactylus breviradix n. sp. The new species differ from other gyrodactylids parasitizing poeciliids in the morphology of superficial bars and hooklets. Gyrodactylus decemmaculati n. sp. has a superficial bar with two robust and rounded anterolateral projections (each with a ventral lobe), and a subtriangular shield, and has a slender hooklet with a delicate recurved point, a straight, elongate shaft, and a depressed, acute toe. Gyrodactylus breviradix n. sp. has a superficial bar with two robust, elongate anterolateral projections, folded inward, and a trapezoidal shield, and has a hooklet with a short point, angled at 90º, ending before level of toe tip, a straight, short shaft, a round, prominent heel, and a pointed, depressed toe. These identifications were supported by DNA analyses based on sequences of the ITS2 region and a barcoding gap analysis. Sequences of the Cytochrome oxidase II gene and fragments of the Internal Transcribed Spacers 1 for both species are also provided.

A synopsis of Microperla (Plecoptera: Peltoperlidae), with a new species from Shaanxi Province of China

A new species of the peltoperlid genus Microperla Chu, 1928, Microperla qinlinga Chen, sp. nov. from Shaanxi Province of northwestern China is described and illustrated. The new species is characterized by the widely rounded ventral lobe in males and the extremely large and bilobed subgenital plate in female. In addition, the taxonomic history and current status of the genus Microperla is reviewed.

A new species of Bryconops (Characiformes: Iguanodectidae) from the Rio Tapajós basin, Brazil

A new species of Bryconops is described from upper rio Juruena drainage, rio Tapajós basin, Amazon basin, state of Mato Grosso, Brazil. The new species is hypothesized as belonging to the subgenus Creatochanes by presenting the posterior extension of maxilla reaching to the junction of second and third infraorbital bones, and the ventroposterior margin of second infraorbital forming a complete border with third infraorbital, resulting in the lack of a naked area between them. The new species is easily distinguished from other species of the subgenus Creatochanes by the color pattern of the caudal fin, which consists of the dorsal lobe conspicuously dark pigmented on its distal half and the ventral lobe dark gray pigmented along its ventral portion below the horizontal through the ventral margin of the caudal peduncle.

STUDI ANATOMIS DAN HISTOLOGIS PANKREAS BIAWAK AIR (Varanus salvator) (Anatomical and Histological Study of the Pancreas of Water Monitor Lizard (Varanus salvator))

The aim of this research was to determine the anatomy and histology of pancreas of water monitor lizard (Varanus salvator). Two pancreas were used in this research (a male and a female). Water monitor lizard was euthanized using chloroform and subsequently necropsied to collect the pancreas. The pancreas was washed in 0.9 % NaCl solution. Anatomical observations were carried out including location, shape, and color of pancreas, also the length and weight measurements. Then, pancreas was fixed with 4% paraformaldehyde for 7 days to proceed to histological preparation and hematoxylin eosin (HE) staining. The results of the anatomical observations showed that pancreas of water monitor lizard have two lobes, dorsal lobe (splenic lobe) and ventral lobe (duodenal lobe). Dorsal lobe which was in oval form adhered with the spleen, and ventral lobe was located in the cranial of intestines with the form of long spherical. Both of pancreas lobes were white-yellow color with the length of 1.45±0.64 cm (dorsal lobe) and 7.00±0.42 cm (ventral lobe). Weight of dorsal lobe was 0.15±0.01 g and ventral lobe was 6.35±2.30 g. The histological observations found the acinar cells, ducts, and blood vessels in both of pancreas lobes. Additionally, the similar structure of Langerhans islet only found at the ventral lobe of pancreas. In conclusion, pancreas of water monitor lizard consists of two lobes which located differently. Ventral lobe is larger than the dorsal lobe. Both lobes have similar histological structure except the Langerhans islets are only appeared in the ventral lobe.
