Due to the absence of more sequences of the species, we could not analyse the intraspecific genetic variability. However, the sequence obtained indicates a clear distinction in relation to the other + +Palaemon +species + +from +Brazil +. In addition, there is no evidence for the proposition of any species closely related to + +P. mercedae + +, since no consistent morphological differences were found within the characters analysed between the Brazilian specimens and those from the +type +locality (Atabapo River, Chamuxina, +Amazonas +, +Venezuela +). Further collecting efforts to obtain specimens suitable for molecular analyses along the species distribution are necessary to evaluate the existence of cryptic species and to re‐evaluate small variations in the external morphology. + + + +Palaemon mercedae + +may present a distribution pattern similar to + +P. ivonicus + ++ + +P. yuna +( +Carvalho et al., 2014 + +), since it occurs both in the Amazon basin and in the Orinoco basin. However, the divergence time between + +P. mercedae + +and + +Palaemon +s.s. + +(estimated at approximately 21 My) is older than the estimates of divergence among the other Amazonian species. Although this value has a wide degree of uncertainty, we suggest that this Amazonian species diverged from + +Palaemon +s.s. + +in an event different from that associated with the other species of this region. + + +Furthermore, the pattern of larval development between + +P. mercedae + +and the other species of the “ + +Palaemon + +” lineage is significantly different. Whereas the land‐locked + +P. mercedae + +exhibits an extremely abbreviated postembryonic development (Magalhães, 1988), the marine or estuarine + +P. argentinus +, +P. floridanus + +, + +P. northropi + +and + +P. paivai + +have extended larval development (Abrunhosa, Costa, Moura, & Pires,2009; +Knowlton & Vargo, 2004 +; +Menu‐Marque, 1973 +; Moura, Abrunhosa, & Pereira Da Costa,1990, respectively). Although the evolution of larval development patterns in palaemonid shrimps does not reflect phylogenetic traits ( +Botello & Alvarez, 2013 +; +Magalhães & Walker, 1988 +; +Murphy & Austin, 2005 +), the high degree of “freshwaterization” shown by + +P. mercedae + +may indicate an early invasion of the continental aquatic habitats and consequently divergence from the other species of + +Palaemon + + +s.s +. + + + +As suggested by Carvalho et al.

Rostral characters, appendix masculina and the anterolateral projection of the first segment of antennular peduncle are also useful for distinguishing the Brazilian species of + +Palaemon +s.s. + + + +Although the external morphology of + +P. ritteri + +and + +P. paivai + +is very similar and overlaps in the diagnostic characters proposed by Fausto Filho (1967), new characters of the appendix masculina proposed herein allow the distinction between them. + +Palaemon paivai + +has a stronger and curved appendix, with a dense row of setae on almost the entire length of the anterior face of the appendix masculina. + +Palaemon ritteri + +has a slender and straight appendix masculina, with a sparse row of setae on the entire length of the anterior face of the appendix (Figure S4). The name + +P. ritteri + +has been attributed to some populations found in +Pará +and +Ceará +( +Ferreira et al., 2010 +; +Gomes‐Correa, 1980 +). However, a population earlier on attributed to + +P. ritteri + +from São João de Pirabas ( +Pará +), and included in our molecular analysis, was allocated outside the clade that includes the Pacific population of this species. Although histone H3 is a conserved gene, the sequence obtained from the +topotype +of + +P. paivai + +allowed the confirmation of a close relationship between individuals from +Pará +and +Ceará +, which were separated from the populations of the Pacific. In addition, analysing the appendix masculina from specimens used in previous works, we discovered that + +P. ritteri + +in +Brazil +represent a misidentification, being + +P. paivai + +in fact. The analysis of the samples from the Atlantic slope of +Panama +and +Venezuela +cited by Holthuis (1952) also revealed higher similarity of the appendix masculina with + +P. paivai + +. Therefore, we suggest that + +P. ritteri + +and + +P. paivai + +are sibling species separated after the complete closure of the isthmus of +Panama +, supporting the use of this lineage as a calibration point for recent phylogenetic divergence in +Palaemonidae +. + + + +Palaemon northropi + +was not recovered as monophyletic. It was intercalated by + +P. floridanus + +specimens, which was described by Chace (1942) from western +Florida +specimens. Some of the characters proposed by Chace (1942) for distinguishing both species were inconsistent in the analysis conducted by Holthuis (1952). Additionally, Knowlton and Vargo (2004) emphasized that the larval morphology of the two species is almost identical. Despite this similarity, Holthuis (1952) maintained + +P. floridanus + +as a valid species and reported that + +P. northropi + +has three or four teeth on the ventral margin of the rostrum and fingers of the second pereopod up to 2/3 of the length of the palm, while + +P. floridanus + +has five to seven teeth and more than 2/3. + + +The topology indicates that the distinction between + +P. northropi + +and + +P. floridanus + +based on the number of dorsal teeth and the relationship between the size of the fingers and the size of the chela may not represent natural groups. Although the morphological distinction between the two species may be easy when + +P. floridanus + +individuals from the Gulf of Mexico are compared to + +P. northropi + +from other regions, this distinction is not very clear when specimens of + +P. floridanus + +from the Caribbean and + +P. northropi + +are compared. Baeza and Fuentes (2013) reported the genetic differentiation between + +P. floridanus + +from the Gulf of Mexico (west coast of Florida) and those from the east coast of Florida. Additionally, they described high similarity between individuals from eastern Florida and +Panama +. These results indicate that the populations of the Gulf of Mexico have a distinct phylogeographic history from the remaining populations, being the result of an event of recent divergence ( +Baeza & Fuentes, 2013 +), which may be associated with the establishment of a morphological pattern in this area, which was recognized by Chace (1942) as compatible with the species level. A similar phylogeographic pattern for the Gulf of Mexico populations of the freshwater shrimp + +Atya scabra +( +Leach, 1816 + +) was discovered by Oliveira, Terossi, and Mantelatto (2019). However, the phylogenetic relationships recovered in the present work indicate that the diagnostic characters of + +P. floridanus + +may be autapomorphies that do not represent a lineage other than + +P. northropi + +. In this context, an expansion of sampling in the Gulf of Mexico, with the inclusion of individuals with more than five teeth in the ventral margin of the rostrum, is essential for a better understanding of the phylogenetic relationships between + +P. floridanus + +and the populations of + +P. northropi + +and to test the representativeness of this character on a possible distinct lineage. + + +A small genetic structuring was observed, with a tendency of separation, between specimens of the North and South Atlantic. As both the +type +localities of + +P. northropi + +and + +P. floridanus + +are in the North Atlantic, taxonomic adjustments may be necessary if the topology is confirmed after the amplification of samples from the Gulf of +Mexico +, resulting in + +P. floridanus + +being placed in the synonymy of + +P. northropi + +. The genetic structuring could justify the revalidation of another synonym, + +Palaemon brachylabis +Rathbun, 1902 + +, whose topotypic specimen (Mamanguape River, +Paraíba +) was included in our analyses and, in general, showed a closer relationship with individuals from the South Atlantic. Nevertheless, low genetic divergence and the absence of morphological characters or other supporting evidence indicate that the genetic structuring found can be attributed to a reduction in gene flow, and this divergence is considered to be at the population level. + + +An unrecorded species for +Brazil +was identified after the molecular comparison of some populations of +Rio de Janeiro +and +Pará +in relation to the other + +Palaemon + +from +Brazil +. Although specimens of the +type +locality of + +P. octaviae +( +Chace, 1972a + +) were not included in the molecular analysis, the absence of distinctive characters between the later species and newly recorded one from +Brazil +allows us to assign the name + +P. octaviae + +to the populations found in +Brazil +. In addition, the first record of + +P. octaviae + +is made herein for +Venezuela +(data in Appendix S1), thus expanding the distribution of the species previously restricted to +Mexico +and Guadalupe to South America ( +Venezuela +and +Brazil +—states of +Pará +and +Rio de Janeiro +). + + + +Palaemon octaviae + +has high morphological similarity with + +P. argentinus + +, as indicated by Chace (1972a). However, the molecular data indicate a clear separation between the two species and differences in the appendix masculina, male thoracic sternite, stout setae of the telson and shape of the rostrum allow the separation between them. Distinguishing + +P. octaviae + +from the species of + +Palaemon +s.s. + +occurring in +Brazil +can be done by the absence of a mandibular palp in + +P. octaviae + +and comparing characters of the rostrum, distal margin of the telson, appendix masculina and the fifth thoracic sternite. + + +Both + +P. octaviae + +and + +P. northropi + +have a wide disjunct distribution, extended larval development (judging by the observed number and size of the eggs), and occur in the same environments. Considering the distribution of + +P. northropi + +in both North Atlantic and South Atlantic with low intraspecific genetic divergence, it is suggested that + +P. octaviae + +may also show the same geographical amplitude. The species has a markedly disjunct distribution in +Brazil +, without records from the north‐east region so far. A comparable pattern was also reported for a recently described alpheid species (Almeida, Terossi, & Mantelatto, 2014), which in +Brazil +occurs in +Pará +, +Bahia +and +São Paulo +, in similar environments to those in which + +P. octaviae + +was collected. Sampling efforts at such environments but including other regions of +Brazil +may reduce distribution gaps, since the absence of structuring on the analysed genes may suggest the existence of recent gene flow in both + +Alpheus petronioi +( +Almeida et al., 2014 + +) and + +P. octaviae + +, and the existence of intermediate populations along the distribution. + + +Alternatively, the current distribution of + +P. octaviae + +may represent a relict distribution as a result of interactions with other species of the group. The sympatric distribution of + +P. octaviae + +and + +P. northropi + +, the ecological similarity between the two species in terms of habitat and some reproductive features, and the larger size of + +P. northropi + +do not allow the rejection, a priori, of the hypothesis of competitive exclusion of + +P. octaviae + +by + +P. northropi + +. This hypothesis is reinforced by the fact that the two species are the result of two distinct colonization events on the American continent (see +Carvalho et al., 2017 +). However, comparative ecological studies with these species are necessary so that the competitive exclusion hypothesis can be tested. + + + + \ No newline at end of file
