Figure 6. Typhlotanais Compactus, Female A In Family Nototanaidae Sieg, 1976 And Typhlotanaidae Sieg, 1984 Author Błażewicz-Paszkowycz, Magdalena text Zootaxa 2007 2007-09-28 1598 1 141 http://dx.doi.org/10.5281/zenodo.178692 journal article 10.5281/zenodo.178692 1175­5334 7604A52C-F935-459C-91DD-F7C7AD9F2CC6 Genus: Hamatipeda n. gen. Diagnosis (female): Pereonite-1 long (subequal or longer than carapace), pereonites 1–5 longer than wide (pereonites 2 and 3 over 1.5 times as long as wide). Mandible molar process with irregular edge but without tubercles and teeth. Maxillipedal endites lack distal tubercles. Chelae smaller than carpus, tapering distally. Pereopods 4–6 merus and carpus with two large specialized hooks, propodus with two long spiniform setae in the distal part of ventral margin, unguis tip trifurcate. Etymology: Named after the large spiniform-setae on pereopods 4–6: hamatus [lat.] = bearing hooks; pedes [lat.] = legs. Type species: Hamatipeda trapezoida n. sp. Gender of generic name: Feminine. Species included : Hamatipeda (= Typhlotanais ) longa ( Kudinova-Pasternak, 1975 ) ; H. trapezoida n. sp. Remarks: Hamatipeda n. gen. lacks prickly tubercles in pereopods 4–6 but, because it also lacks a cheliped ‘side piece’ and the climbing character of pereopods 4–6 is evident, it is included into the family Typhlotanaidae as was Obesutanais .
