Mimonecteola beebei Shoemaker (Figs 40 & 41) Mimonecteola beebei Shoemaker, 1945: 224–228, figs 29, 30. Vinogradov 1956: 199; 1957: 204, fig 11; 1962: 12, fig 7; 1964: 119–120, fig 6. Hurley 1969: 33. Vinogradov 1970: 385 (table). Yoo 1971: 44–45. Vinogradov et al. 1982: 100–102, fig 37. De Broyer & Jazdzewski 1993: 109. Type material. The holotype male and a paratype female are in the USNM (109470 & 109471), in spirit. The type locality is the North Atlantic, off Bermuda [32°12’N 64°36’W]. Material examined. Types: Holotype male, measuring 9.0 mm (USNM 109470) and paratype female, measuring 11.5 mm (USNM 109471) from the North Atlantic, near Bermuda [32°12’N 64°36’W], William Beebe Oceanographic Expedition, col. 8 Sep. 1930 and 15 Jul. 1930 respectively; both trawled from 1000 fathoms. Other material examined. Indian Ocean: Juvenile male (BMNH 1999.2359), near the Seychelles, Sealark exped, 1909. Southern Ocean: Juvenile female (USNM); between South America and Antarctica [67°28’S – 67°11’S 74°39’W – 75°06’W]; Eltanin Stn. 280, 2577 m, 24 Oct. 1962. Diagnosis. Body length of sexually mature females 12.0 mm, of males 11.0 mm (Vinogradov et al. 1982). Antennae 1 slightly longer than head and first 1.5 pereonites combined (medially); peduncular articles and callynophore relatively broader and longer in males; terminal article elongate, marginally longer than preceding two articles combined. Antennae 2 slightly longer than A1. Gnathopod 1; basis marginally shorter than remaining articles combined; dactylus straight, length about half propodus. Gnathopod 2; length 1.4x G1; basis slightly shorter than remaining articles combined; dactylus straight, length about half propodus. Pereopods 3 & 4 similar in structure, with P4 slightly longer than P3; basis length slightly more than twice merus; carpus slightly expanded with several moderate setae on posterior margin, length about twice merus; propodus relatively narrow, subequal in length to carpus; dactylus relatively straight, length about 0.3x propodus. ...
