Genus: Pulcherella n. gen Diagnosis: Carapace almost as long as pereonite-1. Pereonites 1–3 longer than wide; pereonites 5 and 6 wider than long. Mandible molar with teeth or tubercles on margin. Maxilliped bases as wide as long, with long setae (reaching end of endites); endites with two tubercles and with one seta distally. Cheliped bases separated from pereonite-1 by gap ventrally. Pereopod-1 carpus with long seta (over half of propodus length) and unguis with spatulate apex. Pereopods 4–6 carpus with large (about as long as half of article) but flat prickly tubercles, merus with one spiniform and one simple seta; unguis bifurcated. Pleopod rami with gap between most proximal and other setae. Uropod endopod two-articled, exopod one-articled. Exopod little longer than endopod proximal article. Male : Unknown. Etymology: The generic name is derived from the name of the type species Typhlotanais pulcher Hansen, 1913. Type species: Typhlotanais pulcher Hansen, 1913. Gender of generic name: Feminine. Species included: Pulcherella (= Typhlotanais ) pulcher P. (= Typhlotanais ) filatovae (Kudinova-Pasternak, 1975); P. (= Typhlotanais ) spiniventris (Dollfus, 1897); Pulcherella juraszi n. sp. Remarks: Pulcherella n. gen. is characterized by having a carapace shorter than pereonite-1, pereonites 1–3 longer than wide and flat prickly tubercles on pereopods 4–6. The combination of these three character allows clear separation of the new genus from the other typhlotanaids. The long first three pereonites, which are almost as long as the carapace, are elsewhwere found only in the genus Hamatipeda , although in contrast to Pulcherella its members have a trifurcated unguis and strong spines instead of prickly tubercles on the carpus of pereopods 4–6. Further differences can be observed in the mouthparts, where the maxilliped endites have two tubercles distally in Pulcherella and none in Hamatipeda . : Published as part of Błażewicz-Paszkowycz, Magdalena, 2007, Figure 6.
