Three New Species

A taxonomic revision of the pyramidellid genus Eulimella from Brazil was performed based on shell morphology. The holotype of Eulimella rudis Watson, 1886 is illustrated and compared to shells from the southeast Brazilian coast, this being the first confirmed record of this species after its original description. Eulimella smithii (Verrill, 1880), previously known from northern localities in the western Atlantic, is recorded from the southwestern Atlantic, along virtually the entire Brazilian coast; it is herein considered a distinct taxon from Eulimella unifasciata (Forbes, 1844), a very similar species from the eastern Atlantic, given the lack of data on development to consider an amphi-Atlantic distribution. Three new species are described: Eulimella torquata sp. nov., diagnosed by a constriction in the middle of each teleoconch whorl caused by a strong spiral furrow, producing a bilobed whorl profile; Eulimella cylindrata sp. nov., diagnosed by a large subcylindrical teleoconch; and Eulimella ejuncida sp. nov., characterized by its very slender shell, and small protoconch with only one whorl and with an “arc” shaped suture. The shells herein identified as Eulimella cf. calva from Brazil are conchologically identical to Eulimella calva Schander, 1994, from West Africa, but their taxonomic status should remain dubious because of lack of biological information to evaluate a possible amphi-Atlantic distribution pattern. All the species studied (except Eulimella ejuncida sp. nov.) have characteristic short microscopic axial threads organized in a spiral belt, varying in position and expression among species, but usually located in the middle of each teleoconch whorl or below the suture; this characteristic is also present in some species from the eastern Atlantic. Three South American species, originally or subsequently allocated in Eulimella, are herein considered as not belonging to this genus: Eulimella argentina Doello-Jurado, 1938; Eulimella bahiensis Castellanos, 1982; and Eulimella xenohyes (Melvill & Standen, 1912). The holotype of Eulimella lissa is illustrated with SEM micrographs.

Dipsadine snakes of the genus Atractus are endemic to the Neotropical region, occurring from Panama to Argentina. Currently, the taxonomic status of most species of the genus is unclear and previous attempts of taxonomic revisions have been local in scale. In this paper we evaluate the taxonomic status of the Brazilian Atlantic Forest species of Atractus based on meristic, morphometric, maxillary dentition, and hemipenis characters. Quantitative and qualitative analyses suggest the recognition of one new species (A. caete sp. nov.) from the state of Alagoas, another (A. francoi sp. nov.) from the mountainous regions of the states of Rio de Janeiro and São Paulo, and the synonymy of A. kangueryensis with A. thalesdelemai. Specimens previously assigned to A. taeniatus in Argentina and Brazil are here considered A. paraguayensis. A key to the Atlantic Forest Atractus is provided and three new species groups are proposed for some cisAndean Atractus, mainly on the basis of hemipenial morphology: the A. emmeli, A. maculatus, and A. pantostictus species groups.

The South American species of Pseudocanthon Bates, 1887 (Coleoptera: Scarabaeidae: Scarabaeinae: Deltochilini) are reviewed. In this work, 10 valid species and two subspecies are recognized for the genus. Among these species, five are recorded in South America, including three new species: P. perplexus (LeConte, 1847), P. xanthurus (Blanchard, 1847), P. vazdemelloi new species, P. pantanensis new species, and P. chaquensis new species. A lectotype is designated for P. xanthurus (Blanchard, 1847). In this revision, each species is analyzed as follows: a detailed literature review, an identification key for the South American species, a diagnosis, descriptions, illustrations of key morphological characters, list of examined material, and geographic distribution.

A New Species

Snappers of the family Lutjanidae contain several of the most important reef-fishery species in the tropical western Atlantic. Despite their importance, substantial gaps exist for both systematic and ecological information, especially for the southwestern Atlantic. Recent collecting efforts along the coast of Brazil have resulted in the discovery of many new reef-fish species, including commercially important parrotfishes (Scaridae) and grunts (Haemulidae). Based on field collecting, museum specimens, and literature records, we describe a new species of snapper, Lutjanus alexandrei, which is apparently endemic to the Brazilian coast. The newly settled and early juvenile life stages are also described. This species is common in many Brazilian reef and coastal estuarine systems where it has been often misidentified as the gray snapper, Lutjanus griseus, or the schoolmaster, L. apodus. Identification of the new species cast doubt on prior distributional assumptions about the southern ranges of L. griseus and L. apodus, and subsequent field and museum work confirmed that those species are not reliably recorded in Brazil. The taxonomic status of two Brazilian species previously referred to Lutjanus, Bodianus aya and Genyoroge canina, is reviewed to determine the number of valid Lutjanus species occurring in Brazil. Twelve species of Lutjanus are now recognized in the western Atlantic, eight of which occur in Brazil (one endemic). A key for the identification of all western Atlantic Lutjanus species and their known distributional ranges is also provided.

A neotype is designated for Chemnitzia puncta C. B. Adams, 1850, now placed in the genus Turbonilla and considered to be a senior synonym of Turbonilla peilei Dall & Bartsch, 1911, Turbonilla haycocki Dall & Bartsch, 1911 and Turbonilla alfredi Abbott, 1958. Turbonilla obsoleta Dall, 1892, described as a variety of T. puncta, exhibits great deal of intraspecific variation in shell morphology and is considered as valid at the specific level. Turbonilla deboeri Jong & Coomans, 1988, Turbonilla westermanni Jong & Coomans, 1988 and Turbonilla punicea Dall, 1884 share a spiral sculpture pattern very similar to T. puncta, differing in the outline of the whorls, details of the ribs and/or width of the protoconch. Turbonilla puncta, T. deboeri, T. obsoleta and T. westermanni are reported for the first time from the Brazilian coast. Turbonilla tupinamba n. sp. is described from the southeast coast of Brazil and is distinguished from the conchologically related T. puncta and T. deboeri, by the shape of the ribs, outline of the whorls and growth pattern of the shell.

Trindade and Martin Vaz (TMV) is a highly isolated, oceanic volcanic archipelago located some 1200 km off the Brazilian coast and about 4200 km away from the nearest African coast. For almost 100 years Calcinus tibicen (Herbst, 1791) was the only hermit crab species known from TMV. From 2012 to 2018, 263 daytime SCUBA diving and intertidal samplings conducted at TMV yielded 1075 paguroid specimens in 10 species, three of which are established herein as new species: Iridopagurus martinvaz sp. nov., Nematopagurus micheleae sp. nov., and Pagurus carmineus sp. nov. Iridopagurus margaritensis García-Gómez, 1983, and Phimochirus leurocarpus McLaughlin, 1981, both only known from the northern hemisphere, are recorded for the first time from the southwestern Atlantic. Opportunity was taken herein to include hitherto unreported or little known specimens from along the Vitória-Trindade Seamount Chain, namely, Dardanus venosus H. Milne Edwards, 1848, Nematopaguroides pusillus Forest & de Saint Laurent, 1968, Pagurus provenzanoi Forest & de Saint Laurent, 1968, and Phimochirus holthuisi (Provenzano, 1961). The lectotype of Pagurus venosus H. Milne Edwards, 1848 is designated as the neotype for the obscure Pagurus arrosor divergens Moreira, 1905, which thus becomes an objective junior synonym of the former. A list of all paguroid species known from the tropical southern-central Atlantic oceanic archipelagoes and islands (Ascension, Cape Verde, Fernando de Noronha, Gulf of Guinea, Rocas Atoll, Saint Helena, Trindade and Martin Vaz) with their gross distribution in the Atlantic Ocean is provided. Investigation on the existence of patterns of geographic distribution for the paguroid fauna of the tropical southern-central Atlantic oceanic islands showed that 70% percent of the paguroids from TMV are western Atlantic in origin and 30% endemic. No amphi-Atlantic paguroid species are known from TMV. Conversely, the affinity of Ascension’s (33%) and Saint Helena’s (50%) paguroids is with the eastern Atlantic; no western Atlantic paguroids have been reported from these two islands so far. Exploration on the existence of trends of correlation between islands area and species richness through the Spearman’s coefficient of correlation showed that the patterns in the number of paguroid species cannot be explained by variation in island area alone (rs = 0.4728; p = 0.28571).

The ancient Malili lake system on the Indonesian island Sulawesi hosts a large species flock of the viviparous freshwater gastropod Tylomelania. Molecular and morphological data have previously shown that this species flock resulted from three independent lake colonizations and subsequent adaptive radiations. In a recent taxonomic revision of these radiations 25 species have been recognized. Here we describe three new species from the system found during new sampling campaigns. Despite their highly distinct shell morphology, these species were previously overlooked because of their very restricted distribution range and, in one case, the very small size. Of these new species, two are endemic to a section of the Larona River, which drains the entire lake system, while the third species has only been found at one locality in central Lake Mahalona. The discovery of these species can contribute significantly to our understanding of evolution in the entire species flock, as two of the species form a basal branch of an entire clade and all show a high degree of habitat specialization. The local endemism of the Larona River species in particular makes them highly vulnerable to extinction caused by habitat destruction.

A taxonomic revision of the Nystiellidae from Brazil, including samples from the Rio Grande Rise, South Atlantic, was performed based on shell morphology. Five genera and 17 species were recognized. For the richest genus,Eccliseogyra, the three species previously recorded from Brazil were revised:E. brasiliensisandE. maracatu, previously known only from their respective type series, were re-examined. Newly available material ofE. maracatuexpanded the known geographic range of this species to off south-east Brazil.Eccliseogyra nitidais now recorded from north-eastern to south-eastern Brazil, as well as from the Rio Grande Rise. Three species ofEccliseogyraare newly recorded from the South Atlantic:E. monnioti, previously known from the north-eastern Atlantic, occurs off eastern Brazil and on the Rio Grande Rise; its protoconch is described for the first time, confirming its family allocation.Eccliseogyra pyrrhiasoccurs off eastern Brazil and on the Rio Grande Rise, andE. folinioff eastern Brazil. The genusIphitusis newly recorded from the South Atlantic.Iphitus robertsiwas found off northern Brazil, although the shells show some differences from the type material, with less-pronounced spiral keels. Additional new finds showed thatIphitus cancellatusranges from eastern Brazil to the Rio Grande Rise, and Iphitusnotiossp. nov. is restricted to the Rio Grande Rise.Narrimania, previously recorded from Brazil based on dubious records, is confirmed, including the only two living species described for the genus:N. azelotes, previously only known from the type locality in Florida, andN. concinna, previously known from the Mediterranean. A third species,Narrimania raquelaesp. nov. is described from eastern Brazil, diagnosed by its numerous and thinner cancellate sculpture. To the three species ofOpaliopsispreviously known from Brazil, a fourth species,O. arnaldoisp. nov., is added from eastern Brazil, and diagnosed by its very thin spiral sculpture, absence of a varix, and thinner microscopic parallel axial striae.Papuliscala nordestina, originally described from north-east Brazil, is recorded off eastern Brazil and synonymized withP. elongata, a species previously known only from the North Atlantic.
