ABSTRACT

A new species of Moenkhausia is described from the rio Arinos drainage, rio Tapajós basin, Mato Grosso, Brazil. The new species is diagnosed from all congeners, except M . hemigrammoides , M . nigromarginata , and Moenkhausia rubra by having intense diffuse dark pigmentation on the dorsal and anal fin-rays. The new species can be distinguished from the above mentioned species by the combination of 20-23 branched anal-fin rays, presence of a vertically elongate roughly rectangular humeral spot surpassing the lateral line ventrally, absence of a well-defined black spot on the distal portion of the dorsal fin and lack of a series of longitudinal dark zigzag stripes on body. The new species is herein described along with a report and discussion of a possible connection between the rio Tapajós and rio Paraguay basins, near Diamantino Municipality, Mato Grosso.

RESUMO

Uma espécie nova de Moenkhausia é descrita das drenagens do rio Arinos, bacia do rio Tapajós, Mato Grosso, Brasil. A nova espécie é diagnosticada de todas as congêneres, exceto M . hemigrammoides , M . nigromarginata , e Moenkhausia rubra por possuir pigmentação escura intensa e difusa nos raios das nadadeiras dorsal e anal. A nova espécie pode ser distinguida das espécies supracitadas pela combinação da presença de 20-23 raios ramificados na nadadeira anal, presença de uma mancha umeral aproximadamente retangular, ultrapassando a linha lateral ventralmente, ausência de uma mancha negra conspícua na porção distal da nadadeira dorsal e pela ausência de uma série de linhas longitudinais negras em forma de zigue-zague no corpo. A nova espécie é aqui descrita, juntamente com o relato de uma possível conexão entre as bacias dos rios Tapajós e rio Paraguay, próximo ao município de Diamantino, Mato Grosso.

Introduction

Moenkhausia Eigenmann currently includes about 80 valid species (Eschmeyer, 2016Eschmeyer, W. N. 2016. Catalog of fishes: genera, species, references. Available from: Available from: http://researcharchive.calacademy.org/research/ichthyology/catalog/fishcatmain.asp . (1 April 2016).
http://researcharchive.calacademy.org/re... ) widely distributed in South American freshwaters. It is a Characidae genus defined by a combination of the presence of teeth arranged in two rows in the premaxilla, with five teeth in the inner row, lateral line complete, and small scales partially covering the caudal-fin lobes (Eigenmann, 1903Eigenmann, C. H. 1903. New genera of South American fresh-water fishes, and new names for old genera. Smithsonian Miscellaneous Collections 45: 144-148. , 1917Eigenmann, C. H. 1917. The American Characidae. Part IMemoirs of the Museum of Comparative Zoology, 43: 1-102.). None of these characters are unique for the genus and all are known to be highly homoplastic within the Characidae (Mirande, 2010Mirande, J. M. 2010. Phylogeny of the family Characidae (Teleostei: Characiformes): from characters to taxonomy. Neotropical Ichthyology,8: 385-568.). Therefore, the delimitation of Moenkhausia based on such character combination is very likely artificial.

The genus comprises species with a broad variety of body forms and coloration patterns. For example, species of the "Moenkhausia oligolepis/M. sanctaefilomenae- species complex" (Costa, 1994Costa, W. J. E. M. 1994. Description of two new species of the genus Moenkhausia (Characiformes: Characidae) from the central Brazil. Zoologischer Anzeiger, 232: 21-29.; Lima & Toledo-Piza, 2001Lima, F. C. T. & M. Toledo-Piza. 2001. New species of Moenkhausia (Characiformes: Characidae) from the rio Negro of Brazil. Copeia, 2001(4): 1058-1063.; Lima et al ., 2007Lima, F. C. T., H. A. Britski & F. A. Machado. 2007. A new Moenkhausia (Characiformes: Characidae) from central Brazil, with comments on the area relationship between the upper rio Tapajós and upper rio Paraguai systems. Aqua International Journal of Ichthyology, 13: 45-54.; Benine et al., 2009Benine, R. C., T. C. Mariguela & C. Oliveira. 2009. New species of Moenkhausia Eigenmann, 1903 (Characiformes: Characidae) with comments on the Moenkhausia oligolepis species complex. Neotropical Ichthyology, 7: 161-168.) have a characteristic reticulated color pattern on body, red eye and a light area followed by a large dark caudal-peduncle blotch, Moenkhausia browni Eigenmann, M. comma Eigenmann, and M. levidorsa Benine are relatively large species with deep body, M. ceros Eigenmann, M. collettii Steindachner and M. lopesi Britski & de Silimon are small and shallow-bodied forms as well as Moenkhausia bonita Benine, Castro & Sabino and M. hemigrammoides Géry, which are Hemigrammus -like species very similar to H. marginatus Ellis and H. unilineatus Gill, respectively, and M. agnesae Géry and Moenkhausia cosmops Lima, Britski & Machado, with colorful bodies, appreciated as ornamental species.

A recent examination of the species of Moenkhausia deposited in the Museu de Zoologia da Universidade de São Paulo revealed specimens of a undescribed species from the rio Arinos drainage, rio Tapajós basin. The undescribed species have dark fins, similar to M. nigromarginata Costa and M. rubra Pastana & Dagosta. Additional material from the species was later located at Museu de Ciências e Tecnologia da Pontifícia Universidade Católica do Rio Grande do Sul and ZUEC. For color in life description, an expedition to the rio Arinos in the surroundings of Nova Mutum, Mato Grosso was performed. The new species is herein described along with a report and discussion of a possible connection between the rio Tapajós and rio Paraguay basins.

Material and Methods

Morphometric and meristic data follow Fink & Weitzman (1974Fink, W. L. & S. H. Weitzman. 1974. The so-called cheirodontin fishes of Central America with descriptions of two new species (Pisces: Characidae). Smithsonian Contributions to Zoology, 172: 1-46.), except for number of horizontal scale rows below lateral line, counted to the pelvic-fin origin, and with the addition of head depth, measured at vertical through the posteriormost tip of supraoccipital spine. Standard length (SL) is given in millimeters, subunits of body are expressed as percentage of SL, and subunits of head as percentage of head length (HL). In the description, the frequency of each count is provided in parentheses after the respective count, with the count of the holotype indicated by an asterisk. Counts of maxillary tooth cusps, posterior small dentary teeth, supraneurals, branchiostegal rays, gill rakers, vertebrae, unbranched anal-fin rays and procurrent caudal-fin rays are obtained from cleared and stained specimens (c&s) prepared according to Taylor & Van Dyke (1985Taylor, W. R. & G. C. Van Dyke. 1985. Revised procedures for staining and clearing small fishes and other vertebrates for bone and cartilage study. Cybium, 9: 107-119.). Vertebrae of the Weberian apparatus are counted as four elements and the compound caudal centra (PU1+U1) as one element. The sex of five specimens was confirmed by dissection. In the list of type and comparative material, catalog numbers are followed by the number of specimens in alcohol, their SL range, measured and counted specimens and their SL range in parenthesis, and if any, the number of c&s specimens with their SL range. Institutional abbreviations follow Ferraris Jr. (2007Ferraris Jr., C. J. 2007. Checklist of catfishes, recent and fossil (Osteichthyes: Siluriformes), and catalogue of siluriform primary types. Zootaxa, 1418: 1-628.). Figure 3 was produced with the aid of Google Earth (Google Inc.) and Quantum GIS (Geographic Information System - Open Source Geospatial Foundation Project) software in association with geographic maps of IBGE (Instituto Brasileiro de Geografia e Estatística).

Diagnosis. Moenkhausia mutum is distinguished from all congeners, except M . hemigrammoides , M . nigromarginata and Moenkhausia rubra by having intense diffuse dark pigmentation on the dorsal and anal fin-rays, especially in anteriormost rays and in the distal portion (vs . fins hyaliane or only with scattered chromatophores). It can be distinguished from M . rubra by the number of branched anal-fin rays 20-23, modally 21 (vs . 17-20, modally 19) and by having a vertically elongate humeral spot (vs. approximately rounded), from M . hemigrammoides by having pelvic fin intensely dark pigmentated (vs . hyaline), by the anal fin with a relative diffuse dark pigmentation (vs . presence of a black oblique line extending from the urogenital cavity to the tip of second or third branched anal-fin ray), and by lacking a well-defined black spot on the distal portion of the dorsal fin (vs. present), and from M . nigromarginata by lacking a series of longitudinal dark zigzag stripes on body formed by the concentration of dark chromatophores in the upper and lower portions of the exposed area of scales (vs. presence) and by having a vertically elongate roughly rectangular humeral spot surpassing the lateral line ventrally (vs. humeral spot approximately rounded, with an anteroventral projection not surpassing the lateral line ventrally).

Geographic distribution. Moenkhausia mutum is known from the rio Arinos drainage, tributary of rio Juruena, upper rio Tapajós basin, Mato Grosso State, Brazil (Fig. 2).

Fig. 2
Distribution map of Moenkhausia mutum in the upper rio Tapajós basin, Amazon basin. Type locality represented by white star.

Etymology. The specific name mutum is in allusion to the Brazilian popular name of the curassow birds of the genus Crax Linnaeus, which are typically dark colored, as well as the fins of Moenkhausia mutum . Also, the name refers to the Nova Mutum Municipality, the type locality, and where most of the type specimens were collected. A name in apposition.

Conservation status. Moenkhausia mutum is so far known from the rio Arinos drainage, the major tributary of rio Juruena, rio Tapajós basin, where it is widely distributed. Despite existing some riparian forest degradation for pasture in several sites where M . mutum occurs, it seems to not preclude the presence of the species in these areas. Therefore, Moenkhausia mutum would be classified as Least Concern (LC) following the International Union for Conservation of Nature (IUCN) categories and criteria (IUCN Standards and Petitions Subcommittee, 2014IUCN Standards and Petitions Subcommittee. 2014. Guidelines for using the IUCN Red List Categories and Criteria. Version 11. Prepared by the Standards and Petitions Subcommittee. Available from Available from http://www.iucnredlist.org/documents/RedListGuidelines.pdf . (28 April 2015).
http://www.iucnredlist.org/documents/Red... ).

Discussion

A notable condition present in Moenkhausia mutum is the concentration of dark chromatophores at the distal portions of pelvic, dorsal, and anal fins. Among its congeners, this feature is solely present in M . nigromarginata and M . rubra , species also from the upper rio Tapajós basin. The shared presence of such unique color pattern among these species of Moenkhausia along with the similar overall body morphology may indicate that they are closely related. However, phylogenetic studies including these and other species currently assigned to Moenkhausia and related genera are necessary to a proper understanding of the phylogenetic significance of these characters.

It is important to mention two specimens of a putative undescribed species (ZUEC 6352, MZUSP 106156) from the rio Manso (rio Paraguay basin), which shares a similar pigmentation pattern on fins and overall body morphology with the new species. Nevertheless, these specimens lack humeral spot and have more branched anal-fin rays (24 vs . 20-23 in Moenkhausia mutum ) and therefore were herein considered as representing a distinct species.

Two lots of Moenkhausia mutum (MCP 31997 and MCP 32005) were collected at the córrego Caju which, along with córrego Mata Grande and córrego Cedro (Fig. 3), forms the headwaters of the rio Preto, a tributary of the rio Arinos (rio Tapajós basin, Amazon basin). It is noteworthy the great proximity between the headwaters of the córrego Mata Grande (rio Arinos basin) and córrego Macaco (rio Paraguay basin) (Fig. 3). These headwaters are close to such extent, about few ten meters in a relatively flat relief, that it is difficult to precise for sure whether these basins were connected or not before the construction of the BR-364 road (dashed line in Fig. 3), which today separates their headwaters. Further remarkable features of these headwaters are the longitudinal alignment between the córrego Macaco (rio Paraguay basin) and córrego Mato Grande (rio Tapajós basin) and the unusual shape of the córrego Macaco, with an acute angle of nearly 90^o (yellow arrow in Fig. 3), which, together, may be geologically meaningful. Acute angles in water bodies may indicate a stream capture (Bishop, 1995Bishop, P. 1995. Drainage rearrangement by river capture, beheading, and diversion. Progress in Physical Geography, 19: 449-473.; Pederson, 2001Pederson, D. T. 2001. Stream piracy revisited: a groundwater-sapping solution. Geological Society of America - GSA Today, 9: 4-10.; Bharatdwaj, 2006Bharatdwaj, K. 2006. Physical Geography: Hydrosphere. New Delhi, Discovery Publishing House, 356p.; Pastor et al., 2012Pastor, A., J. Babault, A. Teixell & M. L. Arboleya. 2012. Intrinsic stream-capture control of stepped fan pediments in the High Atlas piedmont of Ouarzazate (Morocco). Geomorphology, 173-174: 88-103.). It can be defined as the point where the course of a captured stream has been diverted to the course of the captor stream (Bharatdwaj, 2006Bharatdwaj, K. 2006. Physical Geography: Hydrosphere. New Delhi, Discovery Publishing House, 356p.). A detailed ichthyofaunal inventory in the area would be helpful in the pursuit of shared species, towards an independent confirmation of such geological event in the region.
