            <p> Genus  Ancylocaris Schenkel, 1902</p>
            <p>Type species.</p>
            <p> Ancylocaris brevicarpalis Schenkel, 1902, by monotypy. </p>
            <p>Included species.</p>
            <p> Ancylocaris brevicarpalis Schenkel, 1902 (Figs 1, 3A, B). </p>
            <p>Gender.</p>
            <p>Feminine.</p>
            <p>Diagnosis.</p>
            <p> Subcylindrical body form. Carapace smooth; rostrum well developed, subequal to antennular peduncle and moderately high, dorsal margin convex, dentate, with first tooth postorbital, ventral margin convex, with 1-2 teeth on distal third of rostrum length. Inferior orbital angle produced, without reflected inner flange, supraorbital and epigastric teeth absent, antennal and hepatic teeth present. Fourth thoracic sternite with broad transverse ridge subdivided by deep narrow median incision. Pleon smooth, third tergite non-carinated or posteriorly produced, pleura 1-5 posteroventrally rounded; telson with 2 pairs of minute dorsal spines on distal third of telson length and 3 pairs of short posterior marginal spines. Ophthalmic somite without interocular process. Antennule and antenna as usual for the family; upper ramus of antennular flagellum biramous, with fused basal part; scaphocerite moderately broad, with small distolateral tooth falling short of anterior margin of lamina; carpocerite short.

            <p>Figures</p>
            <p> (selected). Schenkel (1902: Pl. 13, fig. 21), Kemp (1922: figs 40-42, Pl. 6, fig. 8), Kubo (1940: figs 13-14), Miyake and Fujino (1968: fig. 4), Bruce (1978: fig. 6; 1979: Pl. 1, fig. A), Fransen (1989: fig. 1  a–c ). </p>
            <p>Systematic position.</p>
            <p> Ancylocaris brevicarpalis (under the name  Periclimenes brevicarpalis ), together with  Periclimenes inornatus Kemp, 1922,  Periclimenes nevillei Bruce, 2010,  Periclimenes ornatus Bruce, 1969,  Periclimenes ornatellus Bruce, 1979, and  Periclimenes albolineatus Bruce &amp; Coombes, 1997, were previously believed to be members of a "  Periclimenes brevicarpalis " group (see Bruce and Svoboda 1983, Bruce and Coombes 1997, Bruce 2010) some of which are sea anemone associated species. On the contrary, Fransen (1989) stated that only three of those species, i.e.  Periclimenes inornatus ,  Periclimenes ornatellus , and  Periclimenes ornatus , are closely related to each other and comprise a "  Periclimenes inornatus " group (see  Actinimenes gen. n., below), rather than belong in the "  Periclimenes brevicarpalis " group. The available comprehensive molecular phylogenies (Gan et al. 2015,  Horká et al. 2016) show that at least  Ancylocaris brevicarpalis (under the name  Periclimenes brevicarpalis ) occupies a position away from the  Periclimenes inornatus group. </p>
            <p> While the species of the "  Periclimenes inornatus " group share with  Ancylocaris the general shape of the body, especially of the rostrum and the second pereiopods, they may easily be distinguished from  Ancylocaris brevicarpalis by the presence of deeply subspatulate chelae of the first pereiopod, but also by the more numerous proximal teeth on the fingers of the second pereiopod, as well as larger and more anteriorly placed dorsal telson spines (the first pair before mid-length). The propodal segment of the second maxilliped in  Ancylocaris brevicarpalis is broader than the dactylus and distomesially expanded, while sub-equally broad in the "  Periclimenes inornatus " group (e.g. Kubo 1940, Bruce 1979). </p>
            <p> The sister taxon for  Ancylocaris , as revealed by the analyses of Gan et al. (2015) and  Horká et al. (2016), is actually a pair of  Periclimenes species, the crinoid-associated  Periclimenes affinis (Zehntner, 1894) and  Periclimenes kallisto Bruce, 2008, which is symbiotic with antipatharian corals. The significant genetic distance of this pair however indicates that their position is most likely quite distant from  Ancylocaris . Both those species show some resemblance to  Ancylocaris brevicarpalis in the size and position of the dorsal telson dentition, and in the distomedial coxal lobe and fingers on the first pereiopods.  Periclimenes affinis also has a short carpocerite and a similar carpus of the second pereiopod, and similar male pleopod shape and setation.  Periclimenes kallisto has feeble dentition of the fingers of the second pereiopod and the ambulatory dactyli with a minute distoventral tooth. These two species are more slender and smaller than  Ancylocaris brevicarpalis and bear a slender rostrum with obsolete ventral carina, unequal second pereiopods, ventrally spinulose ambulatory propodi, and the endopod of the male first pleopod has a distomedial lobe (Holthuis 1958, Bruce 1980, 2008a). A close affinity between these two species was suggested by Bruce (2008a), who highlighted a group of species of a similar morphology, additionally including  Periclimenes canalinsulae Bruce &amp; Coombes, 1997, and  Periclimenes jugalis Holthuis, 1952. Some other taxa, for instance  Periclimenes novaffinis Bruce &amp; Coombes, 1997,  Periclimenes albolineatus and  Periclimenes nevillei , may also belong to this group. The systematic relation of this assemblage as well as of each particular member to the genus  Ancylocaris remains to be resolved. </p>
            <p>Remarks.</p>
            <p> The earliest report on the present species was published by Zehntner in 1984. However, Holthuis (1952) places  Palaemonella amboinensis Zehntner, 1894 into the synonymy of  Ancylocaris brevicarpalis Schenkel, 1902 under the name  Periclimenes brevicarpalis (Schenkel, 1902), as he considers the drawing of the scaphocerite and the antennular peduncle in Zehntner (1894) not to be entirely correctly drawn. After the examination of a photograph of the holotype (Fig. 1) kindly provided by L. Monod (MHNG) we fully concur with this position.  Palaemonella amboinensis Zehntner (1894) should thus have priority over  Periclimenes brevicarpalis (Schenkel, 1902); however as stated by Holthuis (1952) the latter name is preoccupied by  Periclimenes amboinensis (De Man, 1888), originally described as  Anchistia amboinensis De Man, 1888. For some time now both taxa are no longer considered congeneric, as  Anchistia amboinensis De Man, 1888 was placed in the genus  Laomenes AH Clark, 1919, resurrected for a group of crinoid dwelling species by Okuno and Fujita (2007). Conversely,  Ancylocaris brevicarpalis Schenkel, 1902 was maintained in the genus  Periclimenes up to now, although now returned to the resurrected genus  Ancylocaris . This creates some ambiguity as to what is the correct name for the taxon currently known as  Periclimenes brevicarpalis (Schenkel), a rather widespread, well-known and often photographed species. </p>
            <p> Article 60.1 (ICZN 1999) specifies that a junior homonym must be rejected and replaced either by an available and potentially valid synonym or, for lack of such a name, by a new substitute name. We herein interpret  Holthuis’s (1952) action in proposing to use a junior synonym,  Ancylocaris brevicarpalis Schenkel, 1902, for  Palaemonella amboinensis Zehntner, 1894 as a "substitute name". In which case, Art. 59.3 specifies "that a junior secondary homonym replaced before 1961 is permanently invalid  unless the substitute name is not in use and the relevant taxa are no longer considered congeneric, in which case the junior homonym is not to be rejected on grounds of that replacement". Clearly, the substitute name,  Periclimenes brevicarpalis (Schenkel) is in widespread use, throughout the scientific literature as well as popular accounts, as it is one of the most photographed shrimp species. Even though both taxa have not been considered congeneric since the resurrection of the genus  Ancylocaris makes  Ancylocaris brevicarpalis Schenkel, 1902 the valid name for the species in question. </p>
            <p>Distribution.</p>
            <p> The single species in the genus is widely distributed throughout the whole Indo-West  Paciﬁc , from South Africa and Red Sea to Japan and Polynesia. </p>
            <p>Ecology.</p>
            <p> Ancylocaris brevicarpalis is obligatory associated with sea anemones (  Cnidaria :  Actiniaria ) (cf. Fransen 1989,  Müller 1993), although juveniles may also occur on alcyonarian and scleractinian corals. </p>

            <p>Etymology.</p>
            <p> From  Actiniaria , the order of  Anthozoa which comprises the host sea anemones for the genus, and  Periclimenes to which genus the species previously belonged; gender masculine. </p>
            <p>Figures</p>
            <p> (selected). Kemp (1922: figs 43-46), Bruce (1976: 10-11; 1979: figs 3B, 4-7, Pl. 1: fig.  B–E ; 1982: figs 11-12), Fransen (1989: figs 2-3). </p>
            <p>Systematic position.</p>
            <p> Based on recent molecular studies (Gan et al. 2015,  Horká et al. 2016), species of the genus  Actinimenes gen. n. show a close phylogenetic relationship to two groups of taxa,  Zenopontonia Bruce, 1975 and some other echinoderm-associated taxa on the one hand, and to the  Periclimenes diversipes species group on the other hand. While the latter are also cnidarian associates, they are distinctly smaller species with more slender ambulatory pereiopods and dactyls, but mainly with very distinctive second pereiopods with both or at least one of the chelae of a specific subspatulate shape, with fingers generally longer than palm. Further, the species of the latter group share a similar shape of rostrum, and position of the carapacial teeth, subspatulate first pereiopod chela, short carpus of second pereiopods, simple ambulatory dactyli with elongate sharp unguis, and the shape and spinulation of the male pleopods (Bruce 1989). </p>
            <p> Zenopontonia as well as other related echinoderm-associated taxa, such as  Periclimenes colemani Bruce, 1975, and  Lipkemenes lanipes (Kemp, 1922), are generally also very similar to  Actinimenes by the position of antennal and hepatic teeth, an incised transverse ridge on the fourth thoracic sternite, the deeply subspatulate chelae of the first pereiopod, the shape of the chela of the second pereiopod and the very short carpus, and by the shape and spinulation of the male pleopods (Bruce 1989). These species however differ from  Actinimenes spp. by a more down curved rostrum, more posteriorly situated and smaller dorsal telson spines, fine pectination on the fingers of the first pereiopod, and the ambulatory dactyli having small distoventral tooth on the corpus, sometimes also fully reduced (Marin 2012). Some mollusc- or ascidian-associated genera, e.g.  Anchistus Borradaile, 1898,  Paranchistus Holthuis, 1952, or  Dasella Lebour, 1945, show some phylogenetic relationship to these echinoderm associated taxa (Gan et al. 2015,  Horká et al. 2016), and thus more remotely also to  Actinimenes gen. n. All species of these genera differ however from  Actinimenes gen. n. by specialized biunguiculate ambulatory dactyli. </p>
            <p> The three species of  Actinimenes gen. n. were previously thought to be part of the '  Periclimenes brevicarpalis group’ (Bruce and Svoboda 1983, Bruce 2010), although  Fransen (1989) regarded them as comprising a '  Periclimenes inornatus group’ of identical composition of the new genus (see also Remarks for  Ancylocaris brevicarpalis comb. n., above). </p>
            <p>Distribution.</p>
            <p> Widely distributed in the Indo-West  Paciﬁc from the Red Sea and Kenya to Japan, Marshall Islands, and Fiji. </p>
            <p>Ecology.</p>
            <p> The species of the present genus are all obligate associates of sea anemones (  Cnidaria :  Actiniaria ) (see Fransen 1989,  Müller 1993). </p>

Uropodal exopod elongate, laterally straight, with small distolateral tooth with mobile spine medially. </p>
            <p>Etymology.</p>
            <p> A combination of the subgeneric name  Cristiger (see below) proposed by Borradaile, 1915 and  Periclimenes in which genus the species were previously placed;  gender masculine. As suggested by Holthuis (1993), the etymology of the name  Cristiger (Latin = crest-bearer) was possibly in reference to the convex upper margin of the rostrum in the type species (from crista = crest, and gero = to bear). </p>
            <p>Figures</p>
            <p> (selected). Holthuis (1952: figs 18-19), Miyake and Fujino (1968: fig. 2  e–g ), Bruce (1965: figs 1-2; 1967: figs 26-29; 1982: fig. 2). </p>
            <p>Systematic position.</p>
            <p> The present new genus is closely related to three crinoid-associated genera,  Araiopontonia Fujino &amp; Miyake, 1970,  Laomenes AH Clark, 1919, and  Unguicaris Marin &amp; Chan, 2006. This was already suggested by Marin and Chan (2006), and later supported by phylogenetic analyses (Kou et al. 2013, Gan et al. 2015,  Horká et al. 2016). All these echinoderm-associated shrimps have a well-developed, somewhat downturned rostrum, generally dentate both dorsally and ventrally; the epistome is with a pair of lateral lobes (low, rounded in  Cristimenes gen. n. and  Araiopontonia , but acutely produced in the remaining genera); similar and subequal second pereiopods, and ambulatory legs possessing a specific type of  ‘triunguiculate’ dactylus with a long main unguis. Such dactyli are secondarily reduced to a more biunguiculate state by the reduction of the dorsal spinule in the echinoid-associated species  Cristimenes cristimanus and  Cristimenes zanzibaricus , as well as in the crinoid associated genus  Laomenes . The depressed supraorbital teeth associated with the lateral rostral carina are a synapomorphic character for the group, however, secondarily lost in  Unguicaris . Such a reduction of the supraorbital teeth and lateral carinae was illustrated in some specimens of  Cristimenes commensalis by Monod (1976), or Bruce (1982). </p>
            <p> Cristimenes gen. n., together with  Araiopontonia , can be distinguished from the genera  Laomenes and  Unguicaris by the rounded lateral lobes on the epistome (vs. acute projecting lobes). The new genus differs from all the three genera by a 3-dentate mandibular incisor (vs. distally expanded, multidentate), and by the unique carpo-propodal articulation of the second pereiopods, with the subterminal proximo-ventral articulation on the propodus leaving a distinctive posterior part of the propodus dorsally overhanging the articulation (Fig. 2). This lobe is deeply subdivided by a short but deep longitudinal groove into a pair of lobes which smoothly fit into the dorsal cavity of the short cup-shaped carpus when the propodus is extended anteriad. The proximal end of the propodus is then well hidden inside the carpus from dorsal view. </p>
            <p>Range.</p>
            <p>Widely distributed throughout the whole Indo-West Pacific region.</p>
            <p>Ecology.</p>
            <p> The genus  Cristimenes comprises a single crinoid-associated species,  Cristimenes commensalis comb. n., with the other two species,  Cristimenes cristimanus comb. n., and  Cristimenes zanzibaricus comb. n., living on echinoids (  Echinodermata :  Crinoidea ,  Echinoidea ). </p>
            <p>Remarks.</p>
            <p> The genus  Cristimenes is established here for three species, with  Periclimenes (Cristiger) commensalis as the type species. This species was designated as the type species of the subgenus  Cristiger Borradaile, 1915 by Holthuis (1955) since the previous designation of  Alpheus scriptus Risso, 1822 by Borradaile (1917) as the type was invalid. As pointed out by Holthuis (1955, 1993), the name  Cristiger Borradaile is a junior homonym of  Cristiger Gistel, 1848 (  Hymenoptera ), and thus not available to be used for the present genus. </p>

[  Pennatulacea ]; coll.: N Sirakawa &amp; Y Yamada, lgt. R Minemizu.-1 spm. SW Taiwan, coll. C-W Lin (fcn 20130202-08). </p>
            <p>Diagnosis.</p>
            <p> Medium sized shrimps. Carapace smooth, with antennal and hepatic teeth; epigastric tooth lacking or, if present, clearly separated from them; hepatic tooth subequal and situated posteriorly of antennal tooth and slightly below. Rostrum slender, dorsal lamina bearing 6-10 teeth, ventral lamina obsolete, with 1-2 subterminal teeth. Inferior orbital angle produced, rounded. Pleon smooth, pleura posteroventrally rounded; telson slender, tapering distally, with 1-2 pairs of small dorsal spines and three pairs of posterior marginal spines. Ophthalmic somite without interocular process. Antennula and antenna normal, scaphocerite 3-4 times longer than broad. Eye with globular cornea and small accessory pigment spot, stalk distinctly longer than corneal diameter. Mandible without palp, incisor and molar processes  stout . Maxillula with bilobed palp, upper and lower laciniae well developed. Maxilla with slender palp, well developed scaphognathite, distal (basal) endite bilobed; proximal (coxal) endite lacking. First maxilliped with simple palp, basal endite broad, coxal endite feebly demarcated, exopod well developed, caridean lobe normal, epipod distally bilobed. Second maxilliped with normal endopod and exopod, epipod small, simple, without podobranch. Third maxilliped with slender segments, ischiomerus and basis fused; exopod well developed, coxa with rounded lateral plate, single small arthrobranch present. Fourth thoracic sternites without special structures. First pereiopods slender, fingers narrow, simple, with dense tufts of long setae on sides, coxa with or without distoventral setose process, basis unarmed. Second pereiopods long and slender, distinctly unequal in length; major pereiopod overreaching scaphocerite by distal part of merus in adults; fingers simple, cutting edges entire or with 1-2 feebly developed teeth on proximal third of minor chela, and with 2-4 obtuse proximal teeth on major chela fingers; major pereiopod with palm 2.5-5 times longer than fingers. Ambulatory pereiopods slender, propodus with prehensile structure of long straight distoventral spines arranged to 2-5 pairs, spines longer than distal propodal depth; dactyli slender and curved, simple, or with distinct or minute distoventral tooth. Endopod of first male pleopod with angulate apex and distinct medial lobe; second male pleopod with appendix masculina with 3 terminal serrated setae and 2 lateral setae. Uropods normal; distolateral angle of exopod with small tooth and movable spine medially. </p>
            <p>Etymology.</p>
            <p> Combination of rapina, Latin for claw, to point on the prehensile structures on the ambulatory legs, and the name of the genus  Periclimenes Costa, 1844, from which the new genus is separated; gender masculine. </p>
            <p>Figures</p>
            <p> (selected). Bruce (1978: figs 16-19),  Ďuriš (1990: figs 1-2; 2010: figs 1-8). </p>
            <p>Systematic position.</p>
            <p> Based on the recent molecular phylogeny in  Horká et al. (2016), the therein included two species of  Rapimenes gen. n. are closely related to the genus  Phycomenes Bruce, 2008, and to a pair of further  Periclimenes spp., i.e.  Periclimenes affinis , and  Periclimenes kallisto , positioned near to  Ancylocaris brevicarpalis comb. n. From  Phycomenes , the species of the genus  Rapimenes gen. n., can be easily distinguished by their larger size, distinctly unequal second pereiopods, prehensile ambulatory legs, and lack of a triangular process on the fourth thoracic sternum (see Bruce 2008b,  Ďuriš 2010). Morphologically, the new genus (i.e. the previous "  Periclimenes granulimanus group") is phylogenetically close to the "  Periclimenes obscurus group", as already indicated by Eilbracht and Fransen (2015) who also listed the characters distinguishing all species of those two groups. Included in the "  Periclimenes obscurus group" are some species which show distinct similarities to  Rapimenes , such as  Periclimenes macrorhynchia Eilbracht &amp; Fransen, 2015,  Periclimenes nomadophila Berggren, 1994, and  Periclimenes tonga Bruce, 1988 (the latter synonymized with  Periclimenes granulimanus by Marin 2012, but regarded as valid by Eilbracht and Fransen 2015), particularly in the shape and proportions of the pereiopods and rostrum. These species have biunguiculate walking dactyli, sternal thoracic ridges, and distinct setose coxal lobe on the first pereiopod, i.e. the characters typical for the "  Periclimenes obscurus group". The ambulatory dactyli vary in  Rapimenes spp. from simple to bearing a minute additional  tooth ; the latter is true for  Rapimenes brucei , new comb., for which a coxal setose lobe also was reported (  Ďuriš 1990). It is thus possible that both species groups represent a common evolutionary clade which inner diversity is still to be resolved. </p>
            <p>Distribution.</p>
            <p>Madagascar; Maldive Islands; Indonesia; Vietnam and Taiwan, South China Sea; Japan; Heron Island, Great Barrier Reef, Australia.</p>
            <p>Ecology.</p>
            <p> The species of the present genus have been recorded as associated with antipatharians, hydroids, pennatularians, and scyphozoans (  Cnidaria ) (Bruce 1978, 1988,  Ďuriš 1990, 2010, Minemizu 2013, Eilbracht and Fransen 2015). </p>
            <p>Remarks.</p>
            <p> The generic name  Rapimenes was used as a nomen nudum by Marin (2009: 15) in reference to the then undescribed species  Periclimenes laevimanus Ďuriš (2010), as "  Rapimenes laevimanus Ďuriš &amp; Petrusek (in press)". The name is herein validly reinstated for the genus, indeed now containing  Rapimenes laevimanus . </p>
