( Figs. 3View FIGURE 3 G; 21H; 29B; 36C, D; 49H; 65I)

Chasmocarcinus  sp. C.— Coelho et al. 1980: 39, table III, appendix II [in list].— Barreto et al. 1993: 651 [in list]. Chasmocarcinus hirsutipes Coelho & Coelho, 1998: 804  , 813, figs. 5‒7 [type localilty: Brazil, Pará].— Coelho et al. 2008: 12 [in list].— Ng et al. 2008: 76 [in list]. 

Type material (not examined). Holotype male (DOUFPE 521); Brazil, Pará, Almirante Saldanha , stn 2476, 01°11’N, 47°05.5'W, 44 m.GoogleMaps 

Paratypes: 2 males (MZUSP 13607, ex-DOUFPE 514; see Melo et al. 2003: 431), Proj. Geomar, stn 46, 01°05’N, 47°42.4'W; specimens of unknown sex (DOUFPE 517, DOUFPE 518, DOUFPE 519).

Diagnosis. Anterolateral margins of carapace ( Fig. 3View FIGURE 3 G; Coelho & Coelho 1998: fig. 5a, b) with low granular ridge, setose dorsal surface. Orbits short, proportionally short eye peduncles ( Fig. 21View FIGURE 21 H; Coelho & Coelho 1998: fig. 5c, d). Antennular articles relatively short ( Fig. 21View FIGURE 21 H). Third maxilliped ( Fig. 29View FIGURE 29 B; Coelho & Coelho 1998: fig. 6e) ischium elongated, about same size as elongated merus. Bulging pterygostomial region, clearly visible from dorsal view. Fingers of major chela of holotype male ( Fig. 36View FIGURE 36 C; Coelho & Coelho 1998: fig. 6d, e) setose, proportionally short, slightly shorter than propodus in dorsal view; pollex as long as dactylus. Fingers of minor  chela of holotype male ( Fig. 36View FIGURE 36 D; Coelho & Coelho 1998: fig. 6f) scissor-like; with small, sharp teeth. Inner margin of cheliped carpus with tooth ( Fig. 3View FIGURE 3 G; Coelho & Coelho 1998: fig. 5a). Ambulatory legs ( Fig. 3View FIGURE 3 G; Coelho & Coelho 1998: fig. 5a) setose, proportionally short; no subdistal spur on P5 dactylus. Fused thoracic sternites 1, 2 (Coelho & Coelho 1998: fig. 7a) broadly triangular, proportionally narrow, short. Male pleon ( Fig. 49View FIGURE 49 H; Coelho & Coelho 1998: fig. 7c) with proportionally long, narrow telson, nearly triangular in shape. G1 slightly slender, narrow at base, distal segment with spinules ( Fig. 65View FIGURE 65 I; Coelho & Coelho 1998: fig. 7d). G2, female pleon, thorax, vulvae undescribed.

Remarks. Although no material of this species was examined, the description of the species by Coelho & Coelho (1998) leaves little doubt that it is indeed a separate species on account of its setose carapace and pereiopods and tooth on the inner margin of cheliped merus ( Fig. 3View FIGURE 3 G; Coelho & Coelho 1998: fig. 5).

Distribution. Brazil (Amapá, Pará). Depth: 24‒77 m (Coelho & Coelho 1998).
