Material examined . Campeche Bank (Gulf of Mexico ): SMF 49248, 2 males , 4.1–5.6 mm , 23°50.121’N , 87°10.484’W , 565 m , RV ‘ Maria S. Merian’ MSM 20/4 Station GeoB 163 08-1, BC, 22 March 2012 , on muddy pteropod-foraminiferan ooze, associated with stalked crinoids, sponges, bryozoans, barnacles, brachiopods and few dead scleractinian fragments (mainly Lophelia pertusa (Linnaeus, 1758)) ; SMF 49254, 2 males , 2.8–5.9 mm , 23°49.731’N , 87°10.319’W , 578 m , RV ‘ Maria S. Merian’ MSM 20/4 Station GeoB 163 09-1, BC, 22 March 2012 , no sediment collected—associated with Munidopsis tuerkayi n. sp. , sponges and few dead scleractinian fragments (mainly Lophelia pertusa ). Colour in life. Carapace and abdomen pale brown; P1–4 whitish or pale brown. Cornea pale brown. Remarks . The material examined agrees quite well with the original description. Pequegnat & Williams (1995) compared this species with M. scabra Faxon, 1893 and M. tanneri Faxon, 1893 , both from the eastern Pacific. Munidopsis penescabra is also close to M. acutispina Benedict, 1902 , from the north-east Atlantic and Mediterranean Sea ( Froglia et al. 2002 ; Macpherson & Segonzac 2005 ). The differences are in the following: The dorsal surface of the carapace has numerous small scales each ending in a well-developed spine in M. penescabra , whereas these scales are large each ending in a small spine in M. acutispina . The eyespine is much larger in M. penescabra than in M. acutispina . The suborbital spine is well developed in M. penescabra , whereas this spine is absent in M. acustina . The spines on P1–4 are stronger in M. penescabra than in M. acutispina . Distribution . The species was only known from off Georgia and northwestern Gulf of Mexico , 543– 807 m . The present specimen is from the southeastern Gulf of Mexico , at 565– 578 m .
