“…As anticipated by Myers (), Rosen () and many subsequent authors, one of the most striking patterns is the extreme paucity of primary freshwater fish species, notably ostariophysans, in northern and nuclear Central America. This contrasts with the high species richness of poeciliids and cichlids that originated in South America, became emplaced in northern Middle America in the Paleogene, and later came to dominate the freshwater fish assemblages throughout all of Central America (Morales‐Cazan and Albert, ).…”

Although attempts to understand Central American freshwater fish provincialism date to the 1960s, early efforts lacked the wealth of distributional data now available. Biogeographic work on Central American freshwater fishes has been largely descriptive and regional, and lacked a broader synthesis. Here we use parsimony analysis of endemicity (PAE) to elucidate faunistic relationships between major drainages and to delineate areas of endemism. We then perform a Brooks parsimony analysis (BPA) on the resulting areas. The PAE recovered a primary division between four Pacific and six Atlantic slope areas of endemism. In contrast, the BPA recovered two Central American geographic clades, one sharing a history with North America and the other with South America. Fish diversity is uneven across Central America, with greater diversity in areas adjacent to the more species‐rich regions of North and South America. In northern and nuclear Central America, the paucity of ostariophysan freshwater fishes such as catfishes and characins (groups that dominate adjacent regions) contrasts with high species richness of poeciliids and cichlids. Results of this study are consistent with Myer's hypothesis that poeciliids and cichlids dispersed to Northern or Nuclear Middle America early in the Cenozoic, long before the Plio‐Pleistocene rise of the Isthmus of Panama.

“…Remarks: Regan (1913) initially considered the genus Pseudoxiphophorus as a subgenus within the genus Heterandria Agassiz 1853, Rosen and Bailey (1963) placed Pseudoxiphophorus in synonymy with Heterandria, while other authors recognized Pseudoxiphophorus and Heterandria as different genera (Hubbs, 1924;Miller, 1974). Based on morphological evidence, the genus Pseudoxiphophorus was recognized as valid and Heterandria remained as a monotypic genus with its only known member H. formosa (Morales-Cazan & Albert, 2012). Recently, all Middle American species of the genus Heterandria were reassigned to the genus Pseudoxiphophorus (Morales-Cazan & Albert, 2012).…”

“…In general, the information on the Cyprinodontiforms of El Salvador is relatively scarce, however, some regional studies include in their analyses distributional data and museum specimens collected in the country (e.g. Miller, 1966;Parenti, 1981;Ghedotti, 2000;Hrbek et al, 2007;Matamoros, Kreiser, & Schaefer, 2012;Morales-Cazan & Albert, 2012;Alda et al, 2013;Palacios et al, 2013;Bagley et al, 2015;Matamoros et al, 2015;Ho et al, 2016;Palacios et al, 2016;Reznick, Furness, Meredith, & Springer, 2017;Amorim & Costa, 2018). Even some specimens have been used as holotypes for species descriptions (e.g.…”

Introduction: The Cyprinodontiformes are a group of secondary freshwater fishes widely distributed in El Salvador. Currently, many species of this group are usually incorrectly identified for lack of adequate tools. Additionally, their taxonomy and distribution have changed in recent years. Objective: To provide updated information about the taxonomy and distribution of El Salvador Cyprinodontiformes through identification keys, distribution notes, and general descriptions for all species. Methods: We carried out an extensive review of the literature, electronic databases, and museum specimens to generate a list of valid species present in El Salvador. Results: Eleven species in three families are confirmed: Profundulidae (two species), Anablepidae (one species), and Poeciliidae (eight species). We also include distribution data, both vertical and by main basins, and an illustrated guide. Conclusions: There are 11 species of Cyprinodontiformes in El Salvador and they can be found and identified with this article.

“…Comparative analyses require a good coverage of terminal taxa (species or genera) to allow meaningful inferences. Our analyses included 16 of the 20 genera (we place Heterandria bimaculata in the genus Pseudoxihophorus; Morales‐Cazan & Albert, ), and 50 of the 93 species included in the Poeciliinae phylogeny of Pollux et al. ().…”

Sexually selected sexual selection: Can evolutionary retribution explain female ornamental colour?

By preferring mates with increasingly costly ornaments or courtship displays, females cause an escalation of male reproductive costs. Such increased costs should promote male selectivity based on fecundity‐linked female attributes, leading to female ornamentation in species with traditional sex roles. Consequently, female ornamentation should evolve more frequently in taxa where male reproduction is costly than in comparable taxa where it is cheaper. We assessed the prevalence of female ornamental colouration in two clades of viviparous cyprinodontid fish: the Goodeinae, where stringent female choice imposes male mating costs, and the Poeciliinae, whose males can circumvent female mate choice. We found that although in the Poeciliinae female ornamental colour is a correlated, but paler version of male coloration, females of the Goodeinae often display vivid ornamental colours that are distinct from those of males. Thus, male and female ornaments are not (phylo)genetically correlated in the Goodeinae. Furthermore, phylogenetic signal on male and female colour is clearly detectable in the Poeciliinae, but absent in the Goodeinae, suggesting that ornamental colour of males and females in the latter may be the consequence of selection. Given that enforceable female choice has promoted male ornaments, we propose that evolutionary retribution has promoted distinct female ornaments in the Goodeinae.
