J. (2011): A note on an Ancylomenes (Crustacea: Decapoda: Pontoniinae) from the Siboga expedition.

03EF879FFFCCFF9DFF48FAB8878DDF66.taxon	diagnosis	Diagnosis. Small sized slender shrimp of the genus Ancylomenes Okuno & Bruce. Rostrum (Fig. 1 B) about 0.77 of CL, strongly arched, moderately elevated, ventrally concave, reaching to middle of intermediate segment of antennular peduncle, with 10 small acute teeth dorsally, first tooth situated on carapace, ventral margin concave, setose, with minute acute subterminal tooth; carapace (Fig. 1 A) with inferior orbital angle strongly produced, acute, with reflected inner flange; antennal spine slender, marginal, well below inferior orbital angle, slightly above level of slender hepatic spine, slightly anterior to the level of first dorsal rostral; basicerite with acute dorsal protuberance proximally; third abdominal tergite (Fig. 1 D) slightly posteriorly produced, not carinate; ophthalmic somite (Fig. 1 B) with small rounded ophthalmic process; first pereiopod normal, second pereiopod (Fig. 1 E) chela not bowed (Fig. 1 F), 0.8 of CL, with fingers (Fig. 1 G) about 0.65 of palm length, dactylus with 3 teeth mainly on proximal half, subacute, moderately recurved, tip of dactylus swollen, feebly notched, semi-dentate (Fig. 1 H), fixed finger with 4 small blunt recurved teeth acute teeth proximally, on both fingers the distal tooth well separated from the proximal teeth by feeble diastema; carpus 0.8 of chela length, 0.9 of meral length: ischium subequal to merus length; third ambulatory pereiopod with dactyl biunguiculate, slender (Fig. 1 J), 7.0 times longer than basal width, 0.3 of propod length, with small slender accessory tooth at 0.7 of length, not closely adpressed, unguis not clearly demarcated: propod (Fig. 1 J) about 15.7 times longer than width, with single long distoventral spine, one long ventral spine at 0.75 of propod length, distoventral spine shorter than ventral spine. Systematic position. Closely resembling A adularans (Bruce, 2003). Differs from that species in the following features: Rostral dentition 10 / 1 (vs 11 – 13 / 1), dorsal carina less deep, dorsal margin less strongly convex, first rostral tooth only on carapace, ventral margin with minute distal tooth, inferior orbital angle less acute, without upturned tip, ventral flange feebly developed, antennal spine further removed below inferior orbital angle, almost on same level as hepatic spine (vs at much higher level), second pereiopod with fingers of chela greater than half palm length (vs shorter than palm), fingers with 3 – 4 small recurved teeth (vs dactyl unarmed, fixed finger with 2 small teeth), palm longer than merus (vs shorter), carpus shorter than palm (vs longer), subequal to merus and ischium, ambulatory pereiopod dactylus with accessory tooth less adpressed to unguis (vs strongly adpressed), propod with single long distoventral spine (vs paired distoventral teeth), single extra long ventral spine only (vs with short additional ventral spine).	en	Bruce, A.

03EF879FFFCCFF9DFF48FAB8878DDF66.taxon	etymology	Etymology. The species is named in honour of the late Dr Lipke B. Holthuis, in recognition of his outstanding contribution to the systematics of the Pontoniinae and with thanks for the seminal donation to the author of his last author’s copy of the pontoniine volume of the Siboga Expedition monographs many years ago. The present species is also closely related to Ancylomenes holthuisi (Bruce, 1969).	en	Bruce, A. J. (2011): A note on an Ancylomenes (Crustacea: Decapoda: Pontoniinae) from the Siboga expedition.
