description: <i>Notopoma</i> n.gen. Diagnosis. <i>Antenna</i> 1: peduncular article 1 with dorsodistal flange partially overlapping article 2 and produced medially to form an operculum; without accessory flagellum. <i>Mandibles:</i> left incisor with 4-5 teeth; left lacinia mobilis with 4 teeth; left accessory setal row with 3-4 broad robust setae and 0-3 intermediate plumose setAe; right incisor with 4-5 teeth; right lacinia mobilis with 1 large tooth and a minutely denticulate margin; right accessory setal row with 2 robust setae and 2 plum9Se svtae; mandibular palp short, broad. <i>Maxilla</i> 1: outer plates each with 7-10 setal-teeth. <i>Gnathopod</i> 2: carpochelate in male, subchelate in female. <i>Peraeopods</i> 3 <i>to</i> 7: dactyli all directed posteriorly. <i>Peraeopod</i> 4: merus short, not expanded posteriorly. <i>Peraeopod</i> 5: coxa in femqle subequal or larger than in male, without fringe of long setae; dactylus with large unguis and 1-2 small accessory spines. <i>Peraeopod 6:</i> dactylus with large unguis and 2 small accessory spines. <i>Peraeopod</i> 7: dactylus with large unguis and 1-2 small accessory spines. <i>Pleopod</i> 2: inner ramus reduced, 1­ articulate or pleopod uniramous. <i>Pleopod</i> 3: one reduced I-articulate ramus or pleopod absent. <i>Uropod</i> 2 with one ramus. <i>Uropod</i> 3 with one vestigial ramus bearing small recurved spines. Type species. <i>Notopoma stoddartae</i> n.sp. Species compositipn. <i>Notopoma</i> currently contains 10 species: <i>N. africana</i> n.sp.; <i>N. crassicornis</i> (Bate, 1857); <i>N. fallohidea</i> (Lowry, 1981); <i>N. harfoota</i> (Lowry, 1981); <i>N. lutkini</i> (Tzvetkova, 1990); <i>N. moorea</i> n.sp.; <i>N. opposita</i> (K.H.' Barnard, 1931); <i>N. sismithi</i> (Stebbing, <i>1888</i>) <i>; N. stoddartae</i> n.sp. and <i>N. stoora</i> (Lowry, 1981). Etymology. The name <i>Notopoma</i> is derived from the Greek "poma" for lid and refers to the peduncle of antenna 1 which forms a lid to seal the tube, and "noto" for southern which refers to the distribution of the genus. Remarks. <i>Notopoma</i> differs from <i>Bathypoma</i> in having a carpochelate gnathopod 2 in the male and from all other genera in the <i>Cerapus</i> clade in having an expanded peduncular article 1 on antenna 1. Sars (1894) observed that the peduncular articles function as an operculum in <i>N. crassicornis.We</i> have seen this phenomenon a number of times in preserved specimens still in their tubes. Apparently the antenna geniculates strongly between peduncular articles 1 and 2 so that the distal end of the antenna folds back into the tube leaving the dorsal surfaces of the first peduncular articles to form a cap which closes the tube.
