03AE87C3FF8CFFCFFF33FA4AFE9DF9B6.taxon	discussion	Remarks. The characteristics of the examined material were consistent with the original description provided by Rathbun (1906) and additional taxonomic information provided by Guinot (1969 a) and Hernández Aguilera (1982) for specimens collected in the islands of Central America. Pseudorhombila octodentata differs from the other species occurring in Brazil (P. quadridentata) in the following characters: antero-lateral margin with four teeth (vs. two teeth in P. quadridentata) (Figs. 1 A; 2 A); ocular peduncle with acute lateral granules (vs. less pronounced in P. quadridentata); the external surface of the third maxilliped is granulated (vs. smooth or little granulated in P. quadridentata) (Figs. 1 C; 2 C); merus of the third ambulatory legs with strong and acute spines (vs. granulated in P. quadridentata); the first and second pleonal somites are corrugated (vs. only the first pleonal somite is corrugated in P. quadridentata) (Figs. 1 D; 2 D); well-developed gonopod 1 (G 1), convergent at midline of thoracic sternum, slightly curved, and with few spines at the tip (vs. strongly curved, with several spines at the tip, and showing an apex elevation in P. quadridentata) (Fig. 4 A – D) (see more details in Guinot, 1969 a; Hernández Aguilera, 1982). Pseudorhombila octodentata presents a similar geographic distribution to that of P. quadridentata (Fig. 5), although P. octodentata does not occur in the Gulf of Mexico, only in the South and Southwest regions of Brazil (see P. octodentata distribution topic). However, considering the vertical distribution, P. quadridentata occurs more commonly in shallow waters (between 20 and 64 m) (see remarks under P. quadridentata), and P. octodentata has a bathymetric distribution between 180 and 329 m (Chace, 1940; Gómez and Ortiz, 1976; Martínez-Iglesias and Gómez, 1994). The examined specimen was found at 130 m, thus providing a new shallow record for this species. It is also the first record of this species in the Northeast region of Brazil.	en	Cintra, Flavio de Almeida Alves-Júnior Girlene Fábia Segundo Viana Maria Fernanda Abrantes Torres Kátia Cristina de Araújo Silva Israel Hidenburgo Aniceto (2021): New distributional records of species of the family Pseudorhombilidae Alcock, 1900 (Crustacea: Decapoda) from Brazilian waters.

03AE87C3FF8DFFC8FF5DF98BFBA1FD43.taxon	materials_examined	Material examined. 2 males (CL = 45 – 48 mm; CW = 38 – 41 mm), Revizee / Norte, R / V Almirante Paulo Moreira col., Amapá, Station # 11, (3 ° 40 ’ N 50 ° 25 ’ W), 12 September 1999, 114 m, gravel bottom, MOUFPE: 19994. Geographic distribution. USA (Florida), Gulf of Mexico, Cuba, West Indies, Mexico, Colombia (Atlantic side), and Brazilian states of Amapá (present record), Alagoas, and Bahia (Abrolhos) (Martínez-Iglesias and Gómez, 1994; Melo, 1996; Silva and Calado, 2002; Coelho et al., 2008) (Fig. 5). Remarks. The characteristics of the P. quadridentata specimens examined were consistent with the original description provided by Latreille (1828) and additional remarks prepared by Rathbun (1906), Guinot (1969 a), and Hernández Aguilera (1982). Pseudorhombila quadridentata is widely distributed in the western Atlantic, which is similar to other closely related species (see remarks of P. octodentata), however, with disjunct records especially in the Caribbean Sea (recorded only from Colombia) and in Brazil (only two previous records, in the states of Alagoas and Bahia), but it is a common species in the Gulf of Mexico (see Fig. 5). In Brazil, these records were made by Melo (1996) and Silva and Calado (2002), between the depths of 20 and 64 m, on bottoms of gravel and mud along the continental shelf. However, in the present work, the specimens were found at a depth of 114 m, increasing the bathymetric distribution to deeper waters. Coelho et al. (2008) compiled several records of brachyuran and anomuran crabs from Brazilian waters, however, these records were only based on published literature (without examined material). Thus, the present work is the first record of P. quadridentata from the North region of Brazil (state of Amapá) and only the second record after 18 years for this species.	en	Cintra, Flavio de Almeida Alves-Júnior Girlene Fábia Segundo Viana Maria Fernanda Abrantes Torres Kátia Cristina de Araújo Silva Israel Hidenburgo Aniceto (2021): New distributional records of species of the family Pseudorhombilidae Alcock, 1900 (Crustacea: Decapoda) from Brazilian waters.

03AE87C3FF8BFFCAFEFBFF0DFA72FDDE.taxon	materials_examined	Material examined. 1 male (CL = 12.21 mm; CW = 16.86 mm), Bpot (Potiguar Basin), R / V Seward Johnson col., Rio Grande do Norte, Station # MT- 52 (04 ° 44 ’ S 36 ° 25 ’ W), date: 23 May 2011, 180 m of depth, gravel bottom, MOUFPE: 19231. Geographic distribution. Western Atlantic: Brazilian states of Rio Grande do Norte (Potiguar Basin — present record) and Santa Catarina (Tavares and Gouvêa, 2013) (Fig. 5). Remarks. The characteristics of the R. meridionalis specimens were consistent with the original description provided by Tavares and Gouvêa (2013), who listed some morphological differences between the only two described species of the genus Robertsella. The species of R. meridionalis can be distinguished from R. mystica by the following characters: strongly def lexed frontal region of carapace (Fig. 3 B) (vs. a distinctly less deflected frontal region of carapace in R. mystica); densely and coarsely tuberculate cheliped ischial ridge (vs. less tuberculate cheliped ischial ridge); the merus of the pereiopods P 2 – P 5 is densely and coarsely tuberculate ventrally (vs. the merus of the ventral surface of P 2 – P 5 is smooth); the abdominal suture 5 / 6 is well above the thoracic sternal suture 6 / 7 (Fig. 3 C) (vs. abdominal suture 5 / 6 and thoracic sternal suture 6 / 7 aligned with each other); portion of the thoracic sternite 8 not covered by the lateral expansion of the third abdominal somite (Fig. 3 C) (vs. proportionally larger) (see more characteristics in Tavares and Gouvêa, 2013). The genus Robertsella was recorded only once in the original description of R. meridionalis provided by Tavares and Gouvêa (2013), specifically from the southern region of Brazil (state of Santa Catarina) from a depth of 400 m. Thus, the present work provides a second report of the species R. meridionalis from Brazil (Northeast region - Potiguar Basin) at about 4,200 km distance from the type locality and increases the bathymetric distribution range for this species to 180 – 400 m.	en	Cintra, Flavio de Almeida Alves-Júnior Girlene Fábia Segundo Viana Maria Fernanda Abrantes Torres Kátia Cristina de Araújo Silva Israel Hidenburgo Aniceto (2021): New distributional records of species of the family Pseudorhombilidae Alcock, 1900 (Crustacea: Decapoda) from Brazilian waters.
