GUCLU, Salim Serkan/0000-0002-9256-449X; Kaya, Cuneyt/0000-0002-4531-798XWOS: 000315765700006PubMed: 23794819Alburnoides manyasensis, sp. n., is described from the Koca Stream (Lake Manyas drainage, Marmara Sea basin) in Anatolia. It is distinguished from all species of Alburnoides in Turkey and adjacent regions, Alburnoides tzanevi (Rezovska [Rezve], Istranca and Terkos streams in the western Black Sea drainage), Alburnoides cf. smyrnae (Banaz Stream, a drainage of Buyuk Menderes River, Aegean Sea basin), Alburnoides fasciatus (streams and rivers in the eastern Black Sea drainage) and Alburnoides eichwaldii (Kura and Aras rivers [a drainage of Kura River], Caspian Sea basin) by a combination of the following characters (none unique to the species): marked hump at nape, especially in specimens larger than 60 mm SL; partly developed ventral keel between pelvic fin and anal fin, scaleless 1/2 to 2/3 its length; body depth at dorsalfin origin 29-32% SL; caudal peduncle depth 11-12% SL; 45-52+ 2-3 lateral-line scales; 9-12 scale rows between lateral line and dorsal-fin origin; 4-5 scale rows between lateral line and anal-fin origin, 101/2-121/2 branched anal-fin rays; 40-42 total vertebrae

Opis dviju novih vrsta, Phoxinellus krbavensis i P. jadovensis, rediskripcija vrste P. fontinalis Karaman, 1972 i rasprava o rasprostranjenju vrsta roda Phoxinellus (Teleostei: Cyprinidae) u Hrvatskoj i u Bosni i Hercegovini

Including description of two new species, ten Phoxinellus species are reported from Croatia and Bosnia-Herzegovina. Phoxinellus krbavensis, new species, and Phoxinellus jadovensis, new species, together with P. adspersus and P. ghetaldii, constitute a group which is characterized by an irregular spotted color pattern, an elongate caudal peduncle, a large postcleithrum, an increased number of precaudal anal-fin pterygiophores, and the presence of a large genital papilla in females. P. krbavensis also differs from all congeners in having a short, highly interrupted lateral line formed from small, separated poorly ossified scales, commonly 20–40, extremely reduced body scales, a very short V-A distance, and the highest number of gill rakers (usually 11). P. jadovensis is distinguished from the other species of the group in having a conical slightly pointed snout, a terminal mouth, body scales embedded, poorly ossified, and spaced, and a long lateral line, commonly 51–60 total scales. P. pstrossii, described from the Trebišnjica River is tentatively considered to be a synonym for P. ghetaldii. P. fontinalis, a poorly-known striped Phoxinellus, differs from all other species of the genus in particular by having a strongly laterally compressed, humped body with a straightened ventral profile and a short caudal peduncle, well developed scales, an incomplete interrupted lateral line with (17)23–37(56) total scales, terminating in the area between the pectoral and anal fins, and a rel-atively elongate abdominal vertebral region, total count usually 23+16 or 23+17 with numerous both predorsal (15) and intermediate (5) vertebrae.Zajedno s opisom dviju novih vrsta poznato je deset opisanih vrsta roda Phoxinellus iz Hrvatske i Bosne i Hercegovine. Dvije nove vrste, P. krbavensis i P. jadovensis zajedno s P. adspersus i P. ghetaldii tvore skupinu koju karakteriziraju: nepravilne točkaste šare, izduženi korijen repa, veliki postkleitrum, povećani broj pterigiofora u podrepnoj peraji, te povećana genitalna kvržica kod ženki. P. krbavensis se od srodnih vrsta razlikuje po kratkoj i vrlo isprekidanoj bočnoj pruzi, koju čini najčešće 20 do 40 sitnih razdvojenih i slabo okoštalih ljusaka, veoma kratkoj A–V udaljenosti, te najvećem broju škržnih lukova (najčešće 11). P. jadovensis se razlikuje od drugih vrsta iz skupine po koničnom, blago zašiljenom rostrumu, terminalnim ustima, slabo osificiranim uraslim ljuskama i dugoj neprekinutoj bočnoj pruzi s najčešće ukupno 51 do 60 ljusaka. P. pstrossii opisan iz rijeke Trebišnjice je najvjerojatnije sinonim P. ghetaldii. P. fontinalis je dosad slabo poznata Phoxinellus vrsta koja se razlikuje od ostalih vrsta roda po izrazito bočno spljoštenom grbavom tijelu s izravnatim trbušnim profilom i kratkim korijenom repa, dobro razvijenim ljuskama, nepotpunom i isprekidanom bočnom prugom s ukupno (17)23–37(56) ljusaka koja završava između prsne i podrepne peraje, relativno produženim abdominalnim dijelom kralježnice (najčešće 23+16 ili 23+17) s brojnim predleđnim (15) i središnjim (5) kralješcima

Opis nove vrste, Phoxinellus dalmaticus (Cyprinidae: Leuciscinae), iz rijeke Čikole u slivu rijeke Krke, Jadranski bazen (Hrvatska)

Phoxinellus dalmaticus, new species, is described from the Čikola River in the Krka River system in Croatia. It is distinguished from congeners by a suite of characters which includes a naked body with scales only in a relatively short, often interrupted, lateral line series (sq. l. 18–44) formed from both pored (l. l. 16–29) and unpored scales, a low number of vertebrae (37 or 38 total) with 21 vertebrae in the abdominal and 16 or 17 in the caudal region, a shallowly forked caudal fin with considerably rounded lobes and the lack of a foramen between the cleithrum and coracoid.Nova vrsta Phoxinellus dalmaticus opisana je iz rijeke Čikole u slivu rijeke Krke u Hrvatskoj. Razlikuje se od srodnih vrsta nizom osobina koje uključuju golo tijelo s ljuskama samo u relativno kratkoj, često isprekidanoj lateralnoj seriji linija (sq. l. 18–44), koje čine ljuske s porama (l. l. 16–29) i bez njih, mali broj kralježaka (ukupno 37 ili 38) s 21 kralješkom u abdominalnom i 16 ili 17 u kaudalnom dijelu, plitko urezana repna peraja sa znatno zaobljenim režnjevima i nepostojanje otvora između kleitruma i korakoidne kosti

A recent record of Romanogobio antipai (Actinopterygii, Cyprinidae, Gobioninae) from the Danube River in Bulgaria

The Danube delta gudgeon, Romanogobio antipai, has been considered to be extinct because there were no reliable recent observations. The latest record confirmed by a voucher specimen dating from 1992. We report here on a specimen of R. antipai collected in 2016 in the Bulgarian sector of the Danube main stream using a bottom drift net at a depth of 8 m. The species determination is supported by morphological examination including discriminant and cluster analyses in comparison with three syntypes and five non-type specimens of R. antipai, samples of the R. kesslerii species complex and R. vladykovi. Romanogobio antipai most clearly differs from both R. kesslerii and R. vladykovi by proportional measurements (caudal peduncle depth, head width, eye horizontal diameter, and interorbital width), from R. kesslerii also by the number of scales above and below the lateral line (6 and 4, respectively, (vs. commonly 5 and 3), and from R. vladykovi, also by 8½ branched dorsal-fin rays (vs. 7½) and the vertebral caudal region longer than the abdominal vertebral region (abdominal+caudal vertebrae 19+21 or 20+21, vs. commonly 20+20 or variants with a caudal region shorter than the abdominal one). The possibility that R. antipai represents a deep-water cophenotype of either R. kesslerii or R. vladykovi, cannot be excluded. The new record demonstrates that R. antipai is still extant in the lower Danube but may be restricted to greater depths in the main channel and the deltaic branches

Freshwater ecoregions of the world: A new map of biogeographic units for freshwater biodiversity conservation

We present a new map depicting the first global biogeographic regionalization of Earth's freshwater systems. This map of freshwater ecoregions is based on the distributions and compositions of freshwater fish species and incorporates major ecological and evolutionary patterns. Covering virtually all freshwater habitats on Earth, this ecoregion map, together with associated species data, is a useful tool for underpinning global and regional conservation planning efforts (particularly to identify outstanding and imperiled freshwater systems); for serving as a logical framework for large-scale conservation strategies; and for providing a global-scale knowledge base for increasing freshwater biogeographic literacy. Preliminary data for fish species compiled by ecoregion reveal some previously unrecognized areas of high biodiversity, highlighting the benefit of looking at the world's freshwaters through a new framework.La lista completa de autores que integran el documento puede consultarse en el archivo.Facultad de Ciencias Naturales y Muse

†Kenyaichthyidae fam. nov and †Kenyaichthys gen. nov - First Record of a Fossil Aplocheiloid Killifish (Teleostei, Cyprinodontiformes)

The extant Cyprinodontiformes (killifishes) with their two suborders Cyprinodontoidei and Aplocheiloidei represent a diverse and well-studied group of fishes. However, their fossil record is comparatively sparse and has so far yielded members of the Cyprinodontoidei only. Here we report on cyprinodontiform fossils from the upper Miocene Lukeino Formation in the Tugen Hills of the Central Rift Valley of Kenya, which represent the first fossil record of an aplocheiloid killifish. A total of 169 specimens - mostly extraordinarily well preserved and a sample of ten extant cyprinodontiform species were studied on the basis of morphometrics, meristics and osteology. A phylogenetic analysis using PAUP was also conducted for the fossils. Both the osteological data and the phylogenetic analysis provide strong evidence for the assignment of the fossils to the Aplocheiloidei, and justify the definition of the new family dagger Kenyaichthyidae, the new genus dagger Kenyaichthys and the new species dagger K. kipkechi sp. nov. The phylogenetic analysis unexpectedly places dagger Kenyaichthys gen. nov. in a sister relationship to the Rivulidae (a purely Neotropical group),a probable explanation might be lack of available synapomorphies for the Rivulidae, Nothobranchiidae and Aplocheilidae. The specimens of dagger K. kipkechi sp. nov. show several polymorphic characters and large overlap in meristic traits, which justifies their interpretation as a species flock in statu nascendi. Patterns of variation in neural and haemal spine dimensions in the caudal vertebrae of dagger Kenyaichthys gen. nov. and the extant species studied indicate that some previously suggested synapomorphies of the Cyprinodontoidei and Aplocheiloidei need to be revised
