Two New Species

Curranosia vanemdeni spec. nov. is described from Kenya. The species is characterized by features such as protruding mouthparts, slender proboscis and an anterior seta on mid tibia, which were not previously known to occur in this genus. Curranosia wyatti spec. nov., collected in The Gambia differs from other Curranosia species by wing colour, absence of white dusted markings on the presutural mesonotum, and differences in the numbers of large setae of the body, characters that are more common for the differentiation of species of the genus.   Taxonomic acts Curranosia vanemdeni spec. nov. – urn:lsid:zoobank.org:act:192F65AF-3E14-4DDE-921C-DB840B8A06B4Curranosia wyatti spec. nov. – urn:lsid:zoobank.org:act:971D4E89-CCE4-471D-BAF2-6703B1766324

A New Species

The genus Cicadulina was established in 1926 (Bull. Ent. Res. 17, p. 43) to hold a new species, C. zeae, China, injurious to maize in Kenya Colony. Later (Bull. Ent. Res., 19, 1928, p. 66) it was shown that Balclutha mbila, Naude, recorded as transmitting the virus of streak disease of maize in Natal, also belonged to this genus, and two new species C. arachidis and C. similis were described from the Gambia, where they were reported as injurious to ground-nut and suspected of transmitting the virus of the rosette disease of that plant. Since that time Dr. H. H. Storey of the Amani Research Station has been investigating the possibility of transmission of the streak virus of maize by C. zeae. In attempting to breed strains capable of transmission of the disease certain crosses were made which showed conclusively that he was dealing with two distinct species. These species he was able to separate on the colour pattern of the abdomen. Dr. Storey has now sent to me material of both these species and a study of the genitalia corroborates his finding. One, of course, proved to be C. zeae, the other is new and I therefore propose to dedicate it to the discoverer.

Two new species of the genus Crenicichla from the upper rio Uruguay basin are described, Crenicichla hadrostigma and C. empheres. Both are included in the C. missioneira species group along with C. missioneira, C. minuano, C. tendybaguassu, C. igara, and C. jurubi, all occurring in the upper and middle rio Uruguay drainage. Crenicichla hadrostigma is distinguished by the conspicuous ocellated posttemporal blotch, absence of a humeral spot and lateral band, and the presence in males of nine to 16 narrow vertical bars extending from the dorsum to a horizontal line that passes through the lower edge of pectoral axilla. Crenicichla empheres is distinguished from the other species of the missioneira-group by the presence of six to eight horizontally elongate dark blotches along the middle portion of the body, slightly below the upper lateral line, absence of a lateral band, presence in males of numerous dark and irregularly arranged spots on nape, back, and sides of body, and isognathous mouth. A key to the species from rio Uruguay basin is presented.

Palawan Island

Two new species of Rhinogobius found in streams on central part of Palawan Island, Philippines are described. The two new species, Rhinogobius estrellae and Rhinogobius tandikan share unique transverse rows of sensory papillae on the cheek with Rhinogobius similis Gill, 1859, but differ from the latter in fin ray counts, arrangement of the scales, etc. The two new species are distinguished from each other by the pectoral-fin ray count, the longitudinal- and predorsal-scale counts, and colouration of the body. Rhinogobius estrellae new species and R. tandikan new species have been found allopatrically in a stream within Malatgao River system flowing into the Sulu Sea and in the Cayulo River flowing into the South China Sea, respectively. The Malatgao River system is the southernmost habitat of the genus Rhinogobius. Rhinogobius similis had been considered as the only member of the most basal lineage of this genus, but our mitochondrial genome analysis suggested that the two new species are additional members of this lineage. They are considered to be relicts of their common ancestor with R. similis, which probably had a wider distribution.

Andeogryllus n. gen. including two new species from the inter-Andean slopes and valleys of the Magdalena and Cauca rivers of Colombia are described. This new genus is similar to Zebragryllus in their habitus, differed by not have white stripes on the body or antennae and by a modified pseudoepiphallic sclerite. The genus Atsigryllus (Atsigryllae group) is located in the subtribe Anurogryllina, highlighting the secondary reduction of the median lobe. An updated key is provided for the genera of the subtribe Anurogryllina and the species of the new genus.

Two new species of the genus Styela are described, with very rare characteristics in this genus: both are shallow-water and tropical, with more than two gonads in each side of the body. Styela panamensis sp. nov. is described from specimens collected in Bocas del Toro, Atlantic coast of Panama, and Styela multicarpa sp. nov. from specimens collected in Espírito Santo, Brazil and Margarita Island, Venezuela. They are probably native to the south Caribbean and S. multicarpa sp. nov. is introduced in Brazil.

The present paper deals with the diversity of nephtyid polychaetes (Nephtyidae) from the Sea of Marmara and the Black Sea. Three species belonging to two genera (Micronephthys and Nephtys) were found in the Black Sea (coast of Turkey) and six species belonging to three genera (Inermonephtys, Micronephthys and Nephtys) were found in the Sea of Marmara. The material includes two species new to science, Inermonephtys turcica n. sp. and Nephtys sinopensis n. sp., and a species record (Nephtys kersivalensis McIntosh, 1908) new to the Sea of Marmara’s marine fauna. Nephtys sinopensis n. sp. is mainly characterized by having 1–4 geniculate chaetae in the postacicular position of the parapodia; digitiform antennae, palps, and ventral cirri at chaetiger 1 with swollen tips; small and cirriform branchiae present from chaetiger 4 to the end of the body; poorly developed parapodial prechaetal lamellae in median and posterior chaetigers and long ventral cirri along the body. Inermonephtys turcica n. sp. is mainly characterized by having cushion-like palps with digitiform tips; well developed neuropodial postchaetal lamellae; barred chaetae in preacicular position of the anterior and median parapodia; and branchiae first appearing between chaetiger 3 and 13 (depending on body size).

Salamander Species

Two new species of lungless salamanders (Plethodontidae) are described from high montane habitats of the border region between Costa Rica and Panamá. Bolitoglossa pygmaea and B. robinsoni are distinguished from each other and from other salamander species in this remote area by differences in adult body size, external proportions, foot webbing, tooth counts and/or external coloration. Both new species are assigned to the B. subpalmata species group, subgenus Eladinea. The miniaturized B. pygmaea is remarkable in being extensively depigmented, yet having the peritoneum and stomach area heavily pigmented and visible through the body wall.

Initial Description

A comprehensive material of Afrotropical Sciophila including 262 male specimens of 15 species collected from 7 countries are studied. Two new species—S. geiri sp. n. and S. tchabalensis sp. n.—are described from Madagascar and Cameroon, respectively. New records of the following 13 species are presented: S. digitilenta Søli, 1997 (Uganda), S. fenestralis Søli, 1997 (South Africa), S. kakumensis Søli, 1997 (Cameroon, Uganda), S. kjaerandseni Søli, 1997 (Uganda), S. koundensis Søli, 1997 (Uganda), S. leptosoma Søli, 1997 (Democratic Republic of Congo), S. longistyla Søli, 1997 (South Africa), S. mazumbaiensis Søli, 1997 (Uganda), S. ocreata Philippi, 1865 (France: La Réunion), S. papula Søli, 1997 (Democratic Republic of Congo), S. pinniger Søli, 1997 (South Africa, Cameroon, Uganda, Kenya), S. quadra Søli, 1997 (Democratic Republic of Congo), S. stellata Søli, 1997 (Uganda). The majority of the new records represent the first ones since initial description of the species. S. ocreata is considered to be introduced to the Island of La Réunion. The number of Afrotropical Sciophila species is set at 23.

Two new species of sisorid catfish of the genus Pseudecheneis are described from tributaries of the Ganges River in Nepal: Pseudecheneis crassicauda and P. serracula. Pseudecheneis crassicauda can be distinguished from congeners by a unique combination of 38–39 vertebrae, caudal peduncle depth 6.0–6.6% SL, eye diameter 7.5–8.3% HL, length of adipose-fin base 20.3–24.3% SL, pelvic fins reaching the base of the first anal-fin ray, and the presence of pale spots on the body. Pseudecheneis serracula can be distinguished from congeners in having a unique combination of 36–38 vertebrae, strongly elevated neural spines of the last 2–3 preanal and first 6–7 postanal vertebrae, length of adipose-fin base 26.8–30.4% SL, pelvic fins reaching the base of the first analfin ray, and the presence of pale spots on the body.
