(2004): A new deep water leucosiid genus (Crustacea, Decapoda, Brachyura). Zoosystema 26 (3): 495-502, DOI: http://doi.org/10.5281/zenodo.4689549
775687ED3252E7197BBB4FC0FF797138.taxon	diagnosis	DIAGNOSIS Carapace subhexagonal, globose, granulate; regions of carapace excluding hepatic region indistinct. Front produced, bilobed, uptilted. Postorbital region concave. Antennula folded diagonally into antennular fossa, basal antennular segment sealing lower portion of fossa. Antenna short, inserted into orbit, between antennular fossa and ventral orbital tooth. Orbital margin bifissured dorsally, V-shaped fossa ventrally, triangulate tooth proximally on ventral margin. Eyes retractible. Anterior margin of efferent branchial channel laminate, projecting, unifissured, visible in dorsal view. External maxillipeds concealing trapezoid buccal opening, granulose; exognath shorter, more slender than endognath; merus nearly as long as ischium. Anterolateral margin of carapace sinuous, posterolateral margin rounded. Posterior margin prominent, transverse. Intestinal region tumescent. Chelipeds very long, nearly equal, slender, subcylindrical; longer, more robust, in adult male than in female specimens. Cheliped merus bearing small knob proximally on posterior margin. Propodus somewhat thicker distally; fingers long, their cutting edge unevenly denticulate. Cheliped dactyl of adult male proximally arched. Pereiopods slender, short; dactyls longer than propodi, lanceolate. Male abdominal sulcus deep, elongate, nearly reaching buccal cavity. Male abdomen with segments 3 - 6 fused, narrowing distally, basiolaterally inflated, bearing subdistal tooth, telson triangular; its lateral margin bearing medially vertical ridge fitting into suture between thoracic segments 4 and 5. Adult female abdomen with segments 3 - 6 fused, greatly enlarged, shield-like; telson laciniate. Shaft of male first pleopod flanged on interior margin, elongate, slender, tapering distally. Second male pleopod longer than first pleopod, filiform.	en	Galil, Bella S. (2004): A new deep water leucosiid genus (Crustacea, Decapoda, Brachyura).

775687ED3252E7197BBB4FC0FF797138.taxon	discussion	REMARKS Ancylodactyla n. gen. differs from Praebebalia emend. in having the male abdomen with segments 3 - 6, rather than 3 - 5, fused; lateral margins of carapace rounded rather than medially tuberculate, male second pleopod filiform, longer than first pleopod, rather than short and distally scoop-like; and in lacking spines laterally on the posterior margin of the carapace (Galil 2001). Ancylodactyla n. gen. differs from Randallia s. s. in having the male abdominal somites 3 - 6 fused, antennular operculum sealing only the lower portion of the antennular aperture, the anterior margin of efferent branchial channel bilobate, and the second male pleopod longer than first pleopod (Galil 2003).

DESCRIPTION Dorsal surface of carapace uniformly paved with minute rounded granules. Frontal lobes subtruncate, slightly sinuous. Hepatic region slightly tumid. Anterolateral margins medially constricted. Epibranchial lobe convex, prominent; margin prominently lamellate. Intestinal region inflated, prominent, laterally demarked by shallow grooves. Posterior margin lamellar. Anterior margin of efferent branchial channel narrowly slit medially. Third maxilliped minutely granulate. Chelipeds minutely granulate; merus in adult male about 1.5 as long as carapace; fingers about half as long as propodus. Lower margin of propodus of first pereiopod granulate. Abdominal sternites, somites closely set with minute granules. Subdistal denticle on fused male abdominal segment prominent, medially sulcate. Male first pleopod slightly curved, distally with few marginal setae; second pleopod sinuous, distally curved. REMARKS Zarenkov’s (1994) description and illustrations of Praebebalia elata emphasize the lamellate lateral margins of the carapace, as well as the prominent intestinal region, the keeled pterygostomian margin, the basio-lateral protuberances on fused male abdominal segment, and the shape of the first and second male pleopods. These findings greatly increase the known range of the species.	en	Galil, Bella S. (2004): A new deep water leucosiid genus (Crustacea, Decapoda, Brachyura).

775687ED3251E71F79F44E60FB6070B8.taxon	discussion	REMARKS Zarenkov’s (1969) description and illustrations of Praebebalia elongata emphasize the bidentate subdistal denticle on the fused male abdominal segment. The detailed illustrations of P. bidentata (Chen & Sun 2002) depict the bidentate denticle on the male abdomen, as well as the granulate carapace and cheliped, the keeled lower margin of first pereiopod, and the shape of first and second male pleopods. Examination of Chen’s (1989) single female type specimen of P. semblatae (MNHN B 17975) left no doubt that it is identical with A. elongata n. comb. These findings greatly increase the known range of the species.	en	Galil, Bella S. (2004): A new deep water leucosiid genus (Crustacea, Decapoda, Brachyura).

775687ED3257E71D79F04E00FB977778.taxon	discussion	REMARKS The description and the illustrations of the specimens identified by Zarenkov (1990) as Randallia nana differ from Randallia s. s. (Galil 2003) in having the antennular operculum sealing only the lower part of the antennular aperture, the anterior margin of efferent branchial channel bilobate rather than trilobate, and the segments 3 - 6 of the male abdomen fused, rather than segments 3 - 5. Ancylodactyla nana n. comb. differs from A. elongata n. comb. in its finer granulation on the carapace, lozenge-shaped rather than bidentate subdistal denticle on fused male abdominal segment, and distally coiled second male pleopod. It differs from A. elata n. comb. in lacking lamellate epibranchial margins. These findings greatly increase the known range of the species.	en	Galil, Bella S.
