Gonodactylaceus falcatus was first recorded from Lord Howe Island by Stephenson &amp; McNeill (1955) and reported in detail by Ahyong (2001). The largest specimen in the present series is an adult male (TL 58 mm, AM P100916) but most specimens are juveniles. As observed by Ahyong (2001, 2012) for other specimens from Lord Howe Island and northern New Zealand, the anterior margins of the rostral plate slope posteriorly and the median carinule on abdominal somite 6 is indistinct or absent. The left side of the rostral plate in the TL 58 mm male is deformed, possibly as a result of prior injury.</p> <p>Distribution. Currently attributed a wide range from Eastern Africa and the Red Sea, to Indonesia, Australia, New Caledonia, Japan, Fiji, Hawaii (introduced), French Polynesia and northern New Zealand; intertidal to less than 80 m, possibly 400 m (Ahyong 2012).</p></div> 	https://treatment.plazi.org/id/332D5473FF8C1020FF70FE2CFDF1FAFD	Public Domain	No known copyright restrictions apply.

TL 42 mm, CL 7.90 mm, cornea width 2.15 mm, antennular peduncle 4.84 mm, antennal scale 3.27 mm, raptorial claw propodus length 7.68 mm, abdominal somite 5 width 8.15 mm.</p> <p>Remarks. Acaenosquilla currently includes two species: the type species, A. latifrons (de Haan, 1844), from Japan and Korea (Hwang et al. 2019), and A. brazieri (Miers, 1880) from coastal eastern Australia and New Caledonia (Ahyong 2001). Acaenosquilla keablei sp. nov., the third known species of the genus, is the first lysiosquilloid to be recorded from Lord Howe Island.</p> <p>Acaenosquilla keablei differs from both A. latifrons and A. brazieri in having nine instead of six or seven (usually six) teeth on the dactylus of the raptorial claw. The new species further differs from A. brazieri in having a rounded rather than conical mesial lobe of the cornea and in lacking carinae between the median elevation and submedian carina of the telson. Acaenosquilla keablei is further distinguished from A. latifrons by the presence of the ventral spine on the rostral plate (absent in A. latifrons), sharply defined submedian and intermediate carinae on the telson (versus indistinct) in which the submedian carina is flanked mesially by a small spine (absent in A. latifrons). Acaenosquilla keablei is ecologically unusual in the genus in occurring intertidally. Both other species of Acaenosquilla are currently known only from sublittoral depths: 36–59 m for A. brazieri (see Ahyong 2001), and shallower than 20 m in A. latifrons (see Hwang et al. 2019).</p> <p>Acaenosquilla is closely related to three other Indo-West Pacific tetrasquillid genera sharing five or more teeth on the dactylus of the raptorial claw and a postanal spine on the telson: Heterosquillopsis Moosa, 1991 (type species: H. danielae Moosa, 1991, New Caledonia), Kasim Manning, 1995 (type species: K. philippinensis (Moosa, 1986), South China Sea; K. insuetus (Manning, 1970), southwestern Australia; K. karubar Ahyong, 2002, Indonesia), and Pariliacantha Ahyong, 2012 (type species: P. georgeorum Ahyong, 2012, New Zealand) (Ahyong &amp; Harling 2000; Ahyong 2012). Of these, Acaenosquilla is closest to the monotypic Pariliacantha Ahyong, 2012 from New Zealand, differing chiefly in the armature of the ischium and dactylus of the raptorial claw (ischium unarmed versus with prominent distoventral spine; dactylus with 6–9 versus 12–17 teeth) (Ahyong 2012). Along eastern Australia, A. brazieri is a largely warm-temperate water species ranging from southern Queensland south to Sydney (Ahyong 2001; Hutchings et al., 2013), corresponding the Peronian marine region (Ebach et al. 2013). Discovery of Acaenosquilla on the southern Lord Howe Rise, at an intermediate locality between eastern Australia and northern New Zealand, is biogeographically parsimonious.</p> <p>Distribution. Presently known only from Lord Howe Island; intertidal.</p></div> 	https://treatment.plazi.org/id/332D5473FF8F1022FF70FC04FC6DF845	Public Domain	No known copyright restrictions apply.
