Munidopsis villosa Faxon, 1893

( Fig. 12 )

Restricted synonymy:

Munidopsis villosa Faxon, 1893: 182 .— Luke, 1977: 28 (list).— Wicksten, 1989: 316.— Baba, 2005: 197 –197, 299, fig. 93. Munidopsis villosa chilensis Bahamonde, 1964: 162 , pl. 1, fig. C, D.

Type locality. Gulf of Panama (07°21.00'N, 79°35.00'W, 935 m).

Other records. Arica ( Luke 1977) off Algarrobo (32°20’S – 71°40’W), Chile ( Bahamonde 1964; as M. villosa chilensis ).

Distributional range. Gulf of Panama and off Arica, Chile ( Luke 1977); Off Algarrobo ( Bahamonde 1964).

Bathymetric range. 800–1773 m.

Material examined. Paratype ( MNHNS 10064).

Description. Rostrum triangular ( Fig. 10 a), 3–4 times carapace length. Carapace subrectangular, covered with scale-like tubercles; antennal spine short, not reaching base of antennular peduncle; anterolateral spine robust but short, barely projecting ( Fig. 10 a); gastric region with 2 spines and 2 minor pairs near to margin of region ( Fig. 10 a); dorsal surface flat, no prominent regions; cervical groove shallow; posterior margin unarmed ( Fig. 10 b). Second to fifth abdominal somites with acute, short median spine; pleura unarmed ( Fig. 10 b). Cheliped short, covered by tubercles, without spines; palm longer than wide; fixed finger almost as long as palm; dactyl unarmed ( Fig. 10 c). Walking legs short, almost one and one quarter carapace length ( Fig 10 d). Telson divided in ten plates ( Fig 10 e).

Remarks. We compared the paratype in the MNHNS from Santiago with M. villosa from the collection of the Marine Biology Department of the Panama University (Catalog number 670), and no differences between both specimens were observed.

As was noted by Baba (2005) the figure in Retamal (1981) is not M. villosa chilensis , because of the absence of epigastric and other dorsal spines, and the presence of dorsal marginal spines on the merus of P2–4. No specimens of this species were found in the collections of the MZUC. The figure in Retamal (1981) was probably drawn from the plate of Bahamonde’s paper. No other records of material are known apart from the original descriptions.
