Material examined . Southwestern Atlantic Ocean off Brazil : 1 female (pocl 5.3 mm , rl 2.2 mm ), TAAF MD 55 / BRÉSIL 1987, off Espírito Santo, eastern slope of Abrolhos Bank, station 43 CB 77, 19º00’S 37º47’W , depth: 790–900 m , 27.V.1987 ( MZUSP 31148); 1 ovigerous female (pocl 6.2 mm , rl 2.6 mm ), TAAF MD 55 / BRÉSIL 1987, station 43 CB 77, 19º00’S 37º47’W , depth: 790–900 m , 27.V.1987 ( MZUSP 31149); 1 male (pocl 6.9 mm , rl 2.9 mm ), TAAF MD 55 / BRÉSIL 1987, off Rio de Janeiro, south of Cabo Frio, station 65 CB 106, 23º54’S 42º10’W , depth: 830 m , 02.VI.1987 ( MZUSP 31150). Description . For detailed description and illustrations see Fransen (1990) ; for illustrations of the Brazilian material see Figs. 1 a–g, 2. Distribution . Eastern Atlantic: Azores and Cape Verde , 1100–1350 m ( Fransen 1990 ). Western Atlantic: Brazil , off Espírito Santo and Rio de Janeiro, 790–900 m (present study). Remarks . Bitias stocki was previously known only from the type series: a male holotype and an ovigerous female paratype (allotype) collected at 1320–1350 m south of Pico, Azores, and a female paratype collected at 1100–1300 m southwest of Fogo, Cape Verde ( Fransen 1990 ). The present specimens represent the first record of B. stocki and the genus Bitias from the western Atlantic ( Brazil ). The Brazilian material agrees well with the type material of B. stocki as described and illustrated by Fransen (1990) . The dorsal teeth on the carapace and rostrum are movable (posterior half of the rostrum and carapace posterior to the post-orbital margin) or fixed (distal half of the rostrum); their number ranges from 14 to 16 ( Fig. 1 b, f, g). The ventral subdistal tooth may be present or absent and the development of the lateral rostral carina is also variable ( Fig. 1 b, f, g). An important morphological feature of B. stocki not mentioned nor illustrated in the original description of the species ( Fransen 1990 ) is the presence of sharp processes on the abdominal sternum. All three Brazilian specimens have a pair of spine-like processes on the first to fourth abdominal sternites, strongest on the first and diminishing in size towards the fourth; the fifth sternite has a small median process continued by a median carina. At our request, Dr. Charles H.J.M. Fransen examined the holotype of B. stocki (RMNH D 39051), in which he found the same armature on the abdominal sternum. Dr. Fransen’s schematic drawing is reproduced here ( Fig. 1 h), thereby completing the description of the holotype . The only other presently known species of Bitias is the Indo-West Pacific Bitias brevis ( Rathbun, 1906 ) , which differs from B. stocki in only a few very subtle details ( Crosnier & Fransen 1994 ).
