This study described a new stone loach species in France, Barbatula leoparda, which is endemic to French Catalonia (T{\^e}t and Tech river drainages). Seven specimens were compared to 49 specimens of B. barbatula\ (Linnaeus, 1758) and 71 specimens of B. quignardi (B{\u a}cescu-Me{\c s}ter, 1967). This new species is characterized by the presence of blotches on the belly and the jugular area in individuals longer than 47 mm SL and by a greater interorbital distance (35.5 to 41.8\% of the head length). We brought moreover the sequence of two mitochondrial markers (COI and 12S, respectively 652 and 950 bp) of the holotype, which are well distinct from all other species, for molecular identifications. This discovery is important for conservation.

A new species of the heptapterid genus Mastiglanis, M. durantoni, is described from three adjacent localities in the upper reaches of the Maroni River in French Guyana. The new species is distinguished from the only other known species in the genus, M. asopos, by several qualitative and quantitative characteristics, such as the slender caudal peduncle (caudal peduncle depth 4.3-5.3\% of SL vs. 5.6-6.3\%); the upper jaw protruding markedly beyond lower, resulting in long snout (36.5-42.0\% of HL vs. 23.4-33.6\%); the head depressed (head depth 34.0-44.4\% of HL vs. 44.4-53.0\%); the procurrent caudal fin rays 12 dorsally and ventrally (vs. 14-17); the dorsal margin of adipose fin concave (vs. variably convex, straight or gently sinusoidal); the occipital process deeply notched, distally V-shaped (vs. distal margin of occipital process variably-shaped, with notch, when present, not deep and forming an obtuse angle); the mesethmoid cornu widest at its midlength (vs. gradually narrower from base to tip). Characters of taxonomic and phylogenetic relevance are observed and illustrated with CT-scan imaging technique. The narrowly endemic and outlying geographical distribution of the new species contrasts with the extremely wide range of M. asopos and suggests a history of peripheral isolation and differentiation. In conformity with that interpretation, the new species has some autapomorphic specializations, while none is currently known for M. asopos.

This integrative taxonomy study of French pikes compares morphological characters and molecular sequence data (mitochondrial COI and nuclear Plagl2 genes). In addition to the expected E.\ lucius, DNA sequences and morphology both support a new species in France, E.\ aquitanicus sp. nov. from the Charente to the Adour drainages. It is characterized by a color pattern of sides with narrow 1{\textendash}1.5-scale-wide oblique vertical bands, conferring it a marbled coat, a snout only 0.9 times larger than the postorbital length, an anal fin basis 1.1{\textendash}1.2 times larger than the caudal peduncle length, 101 to 121 lateral scales, 53 to 57 vertebrae, as well as 24 diagnostic sites in the COI gene and 3 in the Plagl2 gene. Partial COI sequences (131bp) from modern and historical specimens indicate also the presence of E.\ cisalpinus and E.\ lucius during the 19th century in Lake Geneva. Morphological and molecular data points to a possible hybridization between E.\ lucius with both other local pike species, representing a risk for them. Their endangerment status should be evaluated rapidly in order to take conservation measures.
