E-mail: [email protected] 2Universidad Nacional de Colombia (Instituto de Ciencias Naturales), Cerro Punta Betín, A.A. 1016 (INVEMAR), Santa Marta, Colombia. E-mail: [email protected] Abstract Notarius armbrusteri n. sp. is described from specimens purchased in the fish market of Buenaventura, Valle del Cauca, Colombia. The species is distinguished from other eastern Pacific species of Notarius by the following combination of features: mouth small, width 11.1–11.8% SL; eye large, diameter 4.3–4.9% SL; distance between anterior nostrils 6.1–6.9% SL, distance between posterior nostrils 5.9–6.9% SL; short maxillary barbels, length 20.5–22.2% SL; and gill rakers on first arch 3–4+8–9 (total 11–13). Based on mitochondrial evidence (cytochrome b and ATP synthase 8/6, total 1937 base pairs), the new species is closely related to N. insculptus, from the Pacific Panama. An updated key to identify the eight described species of Notarius from the eastern Pacific is provided. Key words: Notarius armbrusteri n. sp., Ariidae, sea catfishes, eastern Pacific Introduction The amphiamerican sea catfish genus Notarius Gill was recently revised by Betancur-R. and Acero P. (2004). Notarius includes at least 14 species, with seven distributed in the eastern Pacific (EP). -

Species Assessments
Species Assessments The following 787 species in trade were assessed by researchers at the University of Notre Dame using STAIRfish. Only seven were likely to establish in the Great Lakes. Of these seven, only Ictalurus furcatus (blue catfish), Leuciscus idus (ide), Morone saxatilis (striped bass) and Silurus glanis (Wels catfish) were identified as likely to have a high impact.

O. Birindelli. Licensed under Creative Commons BY-NC. Available: http://eol.org/data_objects/26104614. (August 2018). 1 Native Range and Status in the United States Native Range From Froese and Pauly (2018): “South America: Amazon and Orinoco River basins, north and eastern Guiana Shield rivers, and northeastern Brazilian coastal rivers [Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, Venezuela].” Froese and Pauly (2018) also list Uruguay among the countries where S. rhombeus is native. 1 Status in the United States From Nico and Loftus (2020): “Status: Failed and/or eradicated in Florida. A locally established population south Florida was exterminated in 1977.” “This species was stocked in Florida in an isolated sinkhole pool at Monkey Jungle, a tourist attraction in the Miami area of Dade County in 1963 or 1964. Those fish reproduced and sustained the population for 13 or 14 years until all were killed with rotenone or removed alive by state personnel in September 1977 (Shafland and Foote 1979; identified as Serrasalmus humeralis) (museum specimen). Two specimens were taken from an abandoned swimming pool in South Miami, Dade County (Courtenay et al. 1974). A single fish was taken from a pond in Gainesville, Alachua County in 1985 (museum specimen).” [See Remarks regarding species identity.] This species is currently in trade in the United States. For example: From AquaScapeOnline (2018): “Baby Black Piranha Peru .75"-1" (Serrasalmus Rhombeus [sic]) […] Special 10 for 150.00 Our Price: $25.00” “Black Piranha 4.5" Peru (Serrasalmus Rhombeus [sic]) […] Our Price: $100.00” “Black Piranha 14"-15" Peru (Serrasalmus Rhombeus [sic]) […] Our Price: $1,000.00” Possession or importation of fish of the genus Serrasalmus, or fish known as “piranha” in general, is banned or regulated in many States. -
Revision of the Species of the Genus Cathorops (Siluriformes: Ariidae) from Mesoamerica and the Central American Caribbean, with Description of Three New Species

Marceniuk1 and Ricardo Betancur-R.2 The ariid genus Cathorops includes species that occur mainly in estuarine and freshwater habitats of the eastern and western coasts of southern Mexico, Central and South America. The species of Cathorops from the Mesoamerica (Atlantic slope) and Caribbean Central America are revised, and three new species are described: C. belizensis from mangrove areas in Belize; C. higuchii from shallow coastal areas and coastal rivers in the Central American Caribbean, from Honduras to Panama; and C. kailolae from río Usumacinta and lago Izabal basins in Mexico and Guatemala. Additionally, C. aguadulce, from the río Papaloapan basin in Mexico, and C. melanopus from the río Motagua basin in Guatemala and Honduras, are redescribed and their geographic distributions are revised. O gênero de ariídeos Cathorops inclui espécies que habitam principalmente águas doces e estuarinas das plataformas orientais e ocidentais do sul do México, Américas do Sul e Central. Neste estudo, se apresenta uma revisão das espécies de Cathorops da Mesoamérica (bacias do Atlântico) e Caribe centroamericano, incluindo a descrição de três espécies novas: C. belizensis, de áreas de manglar em Belice; C. higuchii, de águas costeiras rasas e rios costeiros do Caribe centroamericano, desde Honduras até o Panamá; e C. kailolae, das bacias do rio Usumacinta e lago Izabal no México e Guatemala. -

A New Species of Ergasilus (Copepoda: Cyclopoida: Ergasilidae) from Coastal Fishes of the Mexican Pacific
FOLIA PARASITOLOGICA 55: 224–230, 2008 A new species of Ergasilus (Copepoda: Cyclopoida: Ergasilidae) from coastal fishes of the Mexican Pacific Eduardo Suárez-Morales1 and Ana María Santana-Piñeros2 1El Colegio de la Frontera Sur (ECOSUR), Chetumal, Quintana Roo 77900, Mexico; 2Universidad del Mar, Campus Puerto Angel, Oaxaca 70902, Mexico Key words: Copepoda, Ergasilidae, Ergasilus davidi, copepod taxonomy, fish parasites, Tropical Pacific, Mexico, Chiapas Abstract. A new species of the cyclopoid copepod genus Ergasilus von Nordmann, 1832 is described based on adult female specimens removed from the gills of the yellow snapper Lutjanus argentiventris (Peters) and the yellowfin snook Centropomus robalito Jordan et Gilbert from a Pacific coastal system of Mexico. The new species Ergasilus davidi sp. n. has a combination of characters that includes a two-segmented first leg endopod, a three-segmented fourth leg endopod, and the presence of a single seta on the first antennular segment. These characters are shared with 14 other congeners known mainly from Brazil and North America. It differs from these other species in the armature and ornamentation of legs 1 and 4, the shape of the body, and the structure and ornamentation of the antennae. Additional characters include a maxillar basis armed with blunt teeth, distally bent maxillular setae, and naked margins of first exopodal segments of legs 2–4. Previous regional records of Ergasilus sp. from both fish species are probably assignable to E. davidi. The prevalence and intensity of infection was estimated for both teleost species and agrees to previous data. Based on other records of the genus from several other teleost species in the surveyed area and adja- cent zones of the Eastern Pacific, it is presumed that the new species could have a wider range of hosts. -
