AB6C87932351FF8FFF3EFD2CFDF4F923.taxon	materials_examined	Material examined. TALUD XIV, Station 4 (28 ° 10 ' 05 " N, 112 ° 31 ' 59 " W), 7 Apr 2011, 1 male (CL 38.4 mm), 2 females (CL 20.7 and 34.2 mm), 1 ovigerous female (CL 32.6 mm), and 2 juveniles (CL 14.3 and 15.7 mm), benthic sledge, 435 – 451 m, rocky bottom (EMU- 8919). Same station, 2 males (CL 38.3 and 43.0 mm), and 2 ovigerous females (CL 36.5 and 37.6 mm) (EMU- 8920). Same station, 1 male (CL 38.2 mm), and 3 ovigerous females (CL 35.6 – 41.8 mm) (EMU- 8921). Color. Fresh specimens were examined onboard and color photographs (Fig. 2) of freshly collected individuals allow for a precise color description. Carapace white, tips of large spines orange; rostrum white with blush of orange at about mid-length; antenna and antennula dark orange. Chelipeds and walking legs dark orange, tips of large spines white. Size and fecundity. Compared to the 10 specimens reported by Haig (1968) in the original description, the sample from the TALUD XIV cruise is larger and includes much larger specimens: largest male, 43.0 mm CL vs. 26 mm for the male holotype; largest female, 41.8 mm vs. 21.2 mm for the paratypes. No ovigerous females were reported by Haig (1968), but our sample includes six females, with CL ranging from 32.6 to 41.8 mm. Number of eggs per individual is as follow: 139 (CL 32.6 mm); 251 (CL 37.6 mm); 87 (CL 36.5 mm; female partly spent); 174 (CL 35.6 mm); 301 (CL 36.9 mm); 259 (CL 41.8 mm). Egg size of largest female: 1.96 mm (average based on 20 measurements). Ecology. The material of G. perarmatus reported herein was collected in 435 – 451 m depth, in a relatively cold (6.84 ° C) and severely hypoxic (0.21 ml O 2 / l) environment (Table 1). These 14 specimens were collected incidentally. Indeed, the sampling area was selected based on the assumption that the bottom was muddy. Although the sampling device was recovered safely after the trawl, there were clear signs of damages when examined on deck, and the front section of the collecting net was severely torn. Large and small pieces of rock were found in the net, thus indicating that the equipment had been trawled at least for a period of time on hard bottom. Haig (1968) noted that G. perarmatus was collected from green mud, in 229 m depth. Video footage taken by a Remote Operated Vehicle (ROV) in the Gulf of California (JASON dive) are currently being studied and show G. perarmatus associated with a gorgonian, probably of the genus Callogorgia (Fig. 3), fixed on a rocky bottom.	en	Hendrickx, Michel E.

AB6C87932351FF8FFF3EFD2CFDF4F923.taxon	discussion	Remarks. According to Baba et al. (2008), the genus Gastroptychus contains 21 species: two in the Indian Ocean, five in the Atlantic and 16 in the Pacific. Of the 16 species with records in the Pacific Ocean, only five have been found in the eastern Pacific (west coast of America): G. milneedwardsi (Henderson, 1885), from the Straits of Magellan, Chile; G. c a v i m u r u s Baba, 1977, from off Ecuador and Peru; G. defensus (Benedict, 1902) from the Galapagos Islands; G. iaspis Baba & Haig, 1990, from off British Columbia to western Mexico; and G. perarmatus (Haig, 1968), from off California (Hendrickx & Harvey 1999; Baba et al. 2008). Gastroptychus perarmatus was described from a small series of 10 specimens collected north of Anacapa Island, California, at a depth of 125 fm (ca 230 m) and was never found again until now, although it is a large animal (TL is over 21 cm in the largest male examined). The material examined herein fits very well with the original description of Haig (1968), including: the presence of many small spines and the position, size and number of large spines on the carapace; the relative size and orientation of the rostrum; the shape of the sternal plates as well as the position and size of the sternal spines; the length of the chelipeds and the proportion of the joints; and the spination of the walkings legs. The carapace of largest specimens is particularly fragile and somewhat flexible. In largest specimens also the postcervical portion of the carapace is more elevated (Fig. 2 C) than in the holotype illustrated by Haig (1968: fig. 2). Baba (2005) discussed the affinities among species of Gastroptychus, noting that the genus can be divided into two groups. The first features a pair of third maxillipeds widely separated at their base and the anterior end of the sternal plastron somewhat concave and with a row of spines; the second group has the third maxillipeds closely set and the anterior end of the sternal plastron is medially ridged, sloping, and with a pair of spines behind it. Considering that G. spinifer should be included in the group with gaping third maxilliped (K. Baba, pers. comm. May 2011), there are nine species in the former group and 11 in the latter (including G. perarmatus) (see Baba 2005). Gastroptychus meridionalis de Melo-Filho & de Melo, 2004, available after K. Baba’s monograph was in print, features a row of spines on the anterior portion of the sternal plate and the bases of the third maxillipeds are widely gapping, thus indicating it belongs to the first group of species as defined by Baba (2005).	en	Hendrickx, Michel E.

Size and fecundity. Baba & Wicksten (1997) reported a maximum CLr of 22.5 mm for males and 21.2 mm for females. Maximum size (CLr) of material examined herein is 28.7 mm for males, 18.5 for females, and 24.1 for ovigerous females. A total of 37 specimens of J. californiensis were collected, including 12 ovigerous females.

AB6C87932356FF8EFF3EFF3CFB8AFB65.taxon	discussion	Remarks. Hendrickx et al. (2011) recently discussed the geographic and bathymetric distribution of J. californiensis, noting that the oxygen minimum zone that characterizes most of the Gulf of California, seems to play an important role in local distribution of this species. Prior to this study, J. californiensis had been reported in three localities in the Gulf of California, including two “ Velero ” and one GUAYTEC (R / V “ El Puma ”) cruises (see Hendrickx et al. 2011). All three stations were revisited during the TALUD XIV but no specimens of this species were found. The material reported herein is from four sampling stations, thus increasing to seven the total number of known localities within the Gulf of California. Altogether four males, two females, three ovigerous females, and one juvenile have been previously reported from the Gulf of California (Wicksten 1987; Baba & Haig 1997; Hendrickx et al. 2011). Material examined herein includes an additional 37 specimens.	en	Hendrickx, Michel E.

The rediscovery of M. bapensis in samples of the TALUD X cruise in 2007 (488 specimens in one sample; Hendrickx 2008) and present material (405 specimens in six samples) undoubtedly indicate that this species is one of the most abundant galatheids in the northern part of the central Gulf of California. Ecology.

Color. Carapace and pereiopods bright red. Size and fecundity. The type material obviously corresponds to small specimens (18 mm total length, “ from the front to the end of the telson ” [sic]; Benedict, 1902: 275; about 12 mm of maximum CLr, based on illustration by Benedict 1902). The large series of specimens reported by Hendrickx (2000) from 12 stations throughout the northern and central Gulf of California included specimens of up to 16.0 mm CLr. Among the TALUD XIV material examined, the largest male is 34.2 mm CLr and the largest female 29.1 mm CLr. In total 85 specimens were collected, and only two ovigerous individuals of about the same size (CL 17.7 and 18.0 mm) were found among the 41 females, carrying over 1000 eggs each. Egg size: 0.37 – 0.44 mm (based on 20 eggs of largest female). Ecology. Munida tenella was captured in depths of 208 – 414 m (Table 1), much deeper than previously known (70 – 130 m) (Hendrickx 2000). The series of large specimens (CLr> 20.0 mm) captured during the TALUD cruises in depth of 208 – 414 m contrasts with the series of much smaller specimens (CLr <16 mm) reported by Hendrickx (2000) between 27 and 112 m depth. This might indicate that larger specimens occur in deeper water. Epibenthic values of temperature and dissolved oxygen associated with the capture of M. tenella were 11.4 – 13.7 ° C and 0.41 – 2.77 ml O 2 / l, respectively (Table 1).

AB6C8793235BFF83FF3EFC25FB18F930.taxon	discussion	Remarks. Pleuroncodes planipes features both a pelagic and a benthic phase, making it difficult to determine its bathymetric range as specimens are often caught up in trawls hauled back to surface. Within the Gulf of California, the species is known from the east coast, north to about Tiburon Island and it is occasionally very abundant (Hendrickx 1995). In the California Current area, it ranges from San Francisco, California, to the tip of the Baja California Peninsula, then further south to Central America. In the Gulf of California, environmental data indicate that it usually occurs close to the upper limit of the oxygen minimum zone (OMZ) (Hendrickx 1985; Aurioles-Gamboa & Balart 1995). Because the material examined could have been captured at the bottom or during return of the trawl net to surface, it is not possible to relate the epibenthic values of parameters measured at the sampling stations with the presence of P. planipes. In addition to the references provided in the synonymy, P. monodon has been cited in many contributions dealing with its biology, ecology or fishery (Aurioles-Gamboa & Balart 1995; Poore et al. 2011).	en	Hendrickx, Michel E.

AB6C8793235BFF82FF3EF897FB2DFE52.taxon	discussion	Remarks. Previously known from off California and from the Gulf of California (from ca 26 ° N south to off Tres Marias Islands). The present record extends the northernmost limit of M. depressa in the Gulf of California by over two degrees of latitude, to ca 28 ° 16 ’ N. The recorded depth range of M. depressa in the Gulf of California is from 780 to 1300 m, just below the OMZ (Hendrickx 2003). As noted by Hendrickx & Serrano (2010), deep-water species occurring below the OMZ off western Mexico are unable to migrate to shallow water due to the physiological barrier formed by the OMZ and they form a distinct community, with no representative of the continental shelf community.	en	Hendrickx, Michel E.
