Abstract On the basis of fish collections made between 1991 and 2014, four species of the seasonal killifish genus Neofundulus are reported to occur in the Brazilian Pantanal, Paraguay river basin: N. parvipinnis, endemic to the Cuiabá and São Lourenço river drainages, in the northern portion of the Pantanal;

N. rubrofasciatus, new species, from the Miranda river drainage, N. aureomaculatus, new species, from the Aquidauana river drainage, both in the south-eastern portion of the Pantanal; and N. paraguayensis, occurring in the Paraguay and Nabileque river floodplains, in the southern part of the Pantanal. The new species are diagnosed by unique colour patterns, and a combination of morphological characters states indicating that they are more closely related to N. parvipinnis and N. splendidus than to N. paraguayensis. 

Neofundulus splendidus D. T. B. Nielsen & Brousseau, 2013 

Description of a new species of annual fish of the genus Neofundulus (Cyprinodontiformes: Rivulidae) from the upper río Mamoré basin, Bolivia. aqua, International Journal of Ichthyology, 19 (3): 109-114.

Abstract

Neofundulus splendidus n. sp. is described from Bolivia, departamento de Santa Cruz, río San Miguel, upper Mamoré basin. Neofundulus splendidus n. sp. is distinguished from the remaining Neofundulus species by a combination of characters: Large black spot at humeral region with diameter of approximately 1.5-2.0 of pupil in males and females (vs. black spot in humeral region, when present, small- half of pupil), 40-41 scales in longitudinal series (vs. 35-38 in remaining congeners).This is the first record for the genus Neofundulus in río Mamoré basin.

A new genus of miniature cynolebiasine from the Atlantic Forest and alternative biogeographical explanations for seasonal killifish distribution patterns in South America (Cyprinodontiformes: Rivulidae)  (Costa 2014)

 Info:

Abstract The analysis of 78 morphological characters for 16 species representing all the lineages of the tribe Cynopoecilini and three out-groups, indicates that the incertae sedis miniature species ‘Leptolebias’ leitaoi Cruz & Peixoto is the sister group of a clade comprising the genera Leptolebias, Campellolebias, and Cynopoecilus, consequently recognised as the only member of a new genus. Mucurilebias gen. nov. is diagnosed by seven autapomorphies: eye occupying great part of head side, low number of caudal-fin rays (21), distal portion of epural much broader than distal portion of parhypural, an oblique red bar through opercle in both sexes, isthmus bright red in males, a white stripe on the distal margin of the dorsal fin in males, and a red stripe on the distal margin of the anal fin in males. Mucurilebias leitaoi is an endangered seasonal species endemic to the Mucuri river basin. The biogeographical analysis of genera of the subfamily Cynolebiasinae using a dispersal-vicariance, event-based parsimony approach indicates that distribution of South American killifishes may be broadly shaped by dispersal events. The analysis supports south-eastern Brazilian coastal plains as the centre of dispersal for cynolebiasine killifishes. Alternative biogeographical explanations are compared and possible dispersal routes and means of dispersal are discussed.
