Lamarckdromia Guinot & Tavares, 2003 Remarks. McLay (1993) revised the genus Dromidiopsis Borradaile, 1900 to include Dromia globosa Lamarck, 1818, and five other species. The lectotype of Dromia globosa (MNHN B22033) consists of the dried remains of a male, CL = 21.1 mm, of unknown provenance. The recognizable fragments fit most closely with specimens labelled Dromidia excavata Stimpson, 1858 (MNHN B22041) from Sydney Harbour and were therefore believed to be synonyms. Guinot & Tavares (2003) argued that D. globosa did not belong in Dromidiopsis and erected a new genus, Lamarckdromia, for this species. The key features of Lamarckdromia are: all male abdominal segments free (last two fused in Dromidiopsis), uropods concealed (versus uropods conspicuous), apertures of sternal grooves end between P2 (versus apertures end between P1) and uropods not used in the abdominal locking mechanism (versus uropods used to retain abdomen). The conclusion that Lamarckdromia globosa is a senior synonym of Dromidia excavata was reasonable at the time, given the fragmentary nature of the dried material, and because there was apparently only one Australian species. However, closer inspection of Australian material shows that there are two species, Dromidia excavata Stimpson, 1858 and a new species described herein as Lamarckdromia beagle sp. nov. It is not possible to say which, if any, of these two species might be synonymous with Dromia globosa so we conclude that in the absence of more intact specimens of this species it is best to resurrect the name Dromidia excavata and conclude that there are three species in Lamarckdromia. Morphological features of the species are compared in 2.

WAM C25771, Dampier Archipelago, north coast of Goodwyn Island, collected by hand, intertidal, 20°32’S, 116°32.7’E, 31-08-1999, wide intertidal limestone platform with algal turf, large pools, some loose rocks, “much red and green” (?algae): male 10.2 × 9.8 mm, cockle shell carried Vasticardium vertebratum (Jonas, 1844) (= Acrosterigma reeveanum (Dunker, 1852)) (Family Cardiidae). [Some details of these records previously reported by McLay & Hosie 2012.] Diagnosis. Carapace about as wide as long or slightly wider than long, subpentagonal, surface flattened or slightly convex, smooth or finely granulated. Rostrum tridentate, supraorbital margin and anterolateral teeth flattened and eave-like. Chelipeds of similar size to P2, without epipod. Chelipeds and other pereopods armed with long, thin, crest-like ridges. Female sternal sutures ending apart between bases of first walking legs. P4 and P5 reduced, no propodal spines opposing dactyli. All abdominal segments freely movable. Uropods well developed, visible externally and used in abdominal locking mechanism. (After McLay 2001). Distribution. Desmodromia tranterae carries bivalve shells using its last two pairs of legs in a manner similar to Hypoconcha and Conchoecetes. These prehensile limbs are used by all the species in these genera to carry camouflage, each in their own way. The holotype of D. tranterae was dredged (14.7 m) off Ninety Mile Beach, between Broome and Wallal in the Kimberley region. The present specimens were collected from the intertidal to 8.5 m on the same coast around 500 km to the south. Desmodromia griffini McLay, 2001 is known from 10 m depth in Darwin Harbour suggesting that this genus is restricted to shallow waters, from the intertidal zone to 15 m, off northwestern Australia., Published as part of Mclay, Colin L. & Hosie, Andrew M., 2022, The sponge crabs of Western Australia and the Northwest Shelf with descriptions of new genera and species (Crustacea: Brachyura: Dromiidae), pp. 301-355 in Zootaxa 5129 (3) on page 324, DOI: 10.11646/zootaxa.5129.3.1, http://zenodo.org/record/6501010, {"references":["McLay, C L.

The specific name commemorates the importance of the ship HMS “Beagle” that first carried Charles Darwin to Albany, Australia in 1836 during its second voyage (1831–1836) and surveyed and mapped many coastal areas around Australia during the third voyage (1837–1843), captained by Commander John Clements Wickham. Used as a noun in apposition. Description. Carapace about as long as wide, convex, smooth beneath dense cover of long tangled setae, which also covers all limbs and the abdomen. Front weakly vaulted, weak median groove separates pair of low rounded epigastric swellings; branchial grooves evident, lateral cardiac grooves strongly marked with pair of small pits medially. Rostrum tridentate, lateral teeth short, blunt, triangular; similar median tooth strongly deflexed, scarcely visible dorsally when carapace is horizontal. Lateral tooth continuing as supraorbital margin interrupted by small blunt tooth above eyestalk; external orbital corner projecting, evenly rounded and separated by narrow fissure from infraorbital margin, bearing small blunt tooth beneath cornea of eye, visible dorsally. Broad flattened area lateral to orbit, weakly concave, with shorter setae; oral area arranged as most anterior part of face on which longer setae accentuate mouth-frame, pterygostomial surface and orbital margins, making eyes appear deeply sunken. Viewed anteriorly, elongate narrow sunken strip above the eyes and 2 small sunken patches amongst the setae lateral to the orbits. Anterolateral carapace margin obtuse, sinuous, sloping gradually down to weakly concave sub-hepatic area; lower sub-hepatic margin forming convex diagonal edge armed with 3 faint, evenly-spaced convexities; edge connecting epistome to blunt shoulder-like corner, marking widest part of carapace. Carapace margin posterior to widest point convex, interrupted by notch marking branchial groove. Posterior carapace margin weakly concave. Chelipeds fitting closely against inferior carapace surface; both fingers white, curved, gaping widely when closed, hollowed out internally, tips spoon-like, occlusal margins with 7 or 8 teeth, decreasing in size proximally, only distal 3 teeth interlocking. Distal inner edge of carpus without tubercle; inner superior border of propodus with 3 or 4 small rounded proximal tubercles. Cheliped coxae with epipod. P2–3 shorter than cheliped, dactylus curved, well developed, inner margins armed with 4 short spines decreasing in size proximally. P4–5 reduced, last pair shortest, P4 dactyl strongly curved, opposed by well-developed propodal spine; P5 dactyl similar but with 2 to 5 spines at base of dactyl on outer propodal margin, arranged in comb-like row, decreasing in size anteriorly when limb is in normal sub-dorsal position. Abdomen of 6 free segments and telson, uropods reduced to small plates hidden ventrally beneath joint between segment 6 and telson. Male abdominal holding mechanism consisting of well-developed tubercles on P2 coxae, which can be rotated into position at joint between segments 5 and 6, when abdomen is folded. Male without pleopods 3–5. Gonopods stout setose-tipped G1 and long needle-like G2, extending well beyond tip of G1 when engaged. G2 without exopod. Mobile penial tube extending from male P5 coxa, inserted into base of G1 endopod. Female thoracic sternal sutures 7/8 deeply incised into sternum, strongly convergent, ending together on raised sternal area between chelipeds. Tips of sutures 7/8 encased in hardened dark brown secretion (sperm plaque). Posterior margin of female sternite 8 concave, medially depressed to form anvil-shaped pit, separating sternal sutures. Vestigial first pleopods fitting into channels on sternite margins and terminating in anvil pits. Male thoracic sternite 8 with evenly concave posterior margin, not depressed. Remarks. A comparison of morphological characters that separate the three species of Lamarckdromia is given in Table 2. The main differences between the two Australian species are: long shaggy tomentum and tangled mass of setae on the carapace and chelipeds in L. beagle sp. nov. (most of carapace has short even tomentum except for conspicuous post-frontal fringe of longer erect setae across whole width of carapace in L. excavata); median rostral tooth strongly deflexed and scarcely visible dorsally (versus median rostral tooth prominent); post-frontal area of carapace weakly vaulted (versus post-frontal area strongly vaulted, cliff-like; sub-hepatic area weakly concave, ventral margin obtuse, maze-like patches on hepatic area with very short setae (versus strongly excavated, ventral area forms a shelf, almost whole area uniformly covered in short setae); inner superior border of cheliped propodus has 3 or 4 small rounded proximal tubercles (versus inner superior border of cheliped propodus armed with 6 or 7 prominent evenly spaced sub-acute tubercles). The chief difference between the two Australian species and L. globosa is that neither has a strong sub-acute tooth on the anterolateral carapace margin, but they do have a similar row of small tubercles along the inner superior border of the cheliped propodus (see De Man’s 1887: pl. 18 fig. 1) illustration of L. globosa reproduced in Fig. 24b). Distribution. Western Australia; shallow subtidal.

Carapace slightly wider than long, surface gently convex, mostly devoid of setae, finely granulated (especially in frontal area); cardiac and branchial grooves faintly marked. Rostrum tridentate, teeth bluntly triangular, similar in length, median tooth on lower level, lateral teeth separated by broad sulcus extending posteriorly as shallow frontal groove; supraorbital margin interrupted by small tooth, post-orbital corner with small projection, suborbital margin armed with small tooth not visible dorsally. Anterolateral margin initially concave followed by largest tooth and 3 smaller teeth along convex margin interrupted by faint branchial notch (more evident on right hand side. In the present specimen there are some differences between the right and left-hand sides of the carapace. Sub-hepatic area finely granulate with 2 teeth, second larger tooth visible dorsally below margin of post-orbital concavity. Cheliped merus inner face smooth, flattened; carpus flattened armed with 3 prominent unequal tubercles on outer face; propodus superior face bearing 3 smaller tubercles, outer face with several small granules some arranged in rows; fingers white, down curved, not gaping widely, margins armed with 8 or 9 small interlocking occlusal teeth. P2–3 shorter than cheliped; flattened, ridged, tuberculate, especially on distal ends of articles; dactylus short, curved, inner margin armed with 2 strong spines. Merus and propodus of P1 and P2 with entire dorsal crests. P3–4 reduced, used to carry camouflage cap, P4 shortest, P5 flattened sub-dorsal, dactylus opposed by single, long, propodal spine. Abdomen fringed with short dense setae. Telson of mature female much wider than long, posterior margin strongly truncated; uropods visible externally. Abdominal surface strongly ridged along axis, with concave sulcus on each side; lateral margins of segments 3–5 each with small blunt tubercle. Female thoracic sternal grooves deeply marked, converging but ending apart on low swellings between bases of P2. Remarks. Distinctive features of S. lamellata are the finely granulated carapace with granules extending on to the subhepatic area and third maxillipeds, anterolateral margin shoulder-like armed with unequal teeth, merus and propodus of chelipeds and walking legs flattened with dorsal crests or lamellae, telson posterior margin truncate (see also Griffin 1972).

WAM C13507, Port Willunga, intertidal limestone reef platform under rocks, 22-01-1965: male 17.0 × 15.0 mm (sponge cap). Description. Carapace wider than long, convex, smooth, regions not defined, covered by short dense tomentum. Rostrum tridentate lateral teeth broadly triangular, rounded, median tooth shorter, sharper, at lower level, slightly deflexed; supraorbital margin continues interrupted by weak supraorbital tooth and similar postorbital tooth, suborbital tooth more prominent. Anterolateral margin armed with 2 similar blunt teeth and strong subhepatic tooth visible dorsally between postorbital corner and first anterolateral tooth; margin between 2 anterolateral teeth convex; well defined posterolateral tooth behind branchial notch. Chelipeds well developed, tubercular, inner surface of carpus and propodus densely setose, dorsal surface tends to be flattened with poorly defined ridge running along inner border; fingers white and gaping. Outer face of cheliped propodus sometimes with fine tubercles tending to be arranged in longitudinal rows. P2 and P3 also with strong distal tubercles on dorsal margins. P4 and P 5 smaller, dactyli opposed by single propodal spine with another similar spine on outer propodal margin. Posterior margin of telson broadly rounded, subtruncate. Female thoracic sternal grooves ending well apart on small tubercles between P2 coxae. Remarks. The true identity of Cryptodromia lateralis was uncertain until Stimpson (1907: pl. 20 fig. 3) published a figure of this species, based on material collected from Port Jackson, i.e., Sydney Harbour. The differences between S. lateralis and S. lamellata include: carapace tomentose and smooth (versus bare and granular in S. lamellata); rostral teeth unequal (versus teeth approximately same size); anterolateral carapace margin armed with two teeth (versus three irregular teeth); cheliped and P1 and P2 tubercular on distal ends of carpi and propodi (versus crest-like). Brood young are carried by female (Montgomery 1922). Distribution. Endemic to Australia, found around most of the coastline. Old records of this species from New Zealand refer to Metadromia wilsoni (Fulton & Grant, 1902). Miers’ (1884) records of S. lateralis based on specimens from Bohol, Philippines and Madjicasima, Japan, (HMS Samarang) in the NHM need verification.

Description (based on male, WAM C6517). Entire body and pereopods covered by short, sparse bristly tomentum, somewhat denser on chelipeds and P2–3. Carapace smooth after removal of tomentum, tumid, rising steeply behind rostrum and frontal margins, then sloping gradually down to posterior margin; overall shape changing during ontogeny from approximately as wide as long to much wider than long, ratio ~1.22 (see Remarks below); rostrum tridentate, strongly deflexed, all 3 teeth similar short, sub-acute, median tooth on lower level; similar teeth on supra-orbital margin and at postorbital corner; sub-orbital margin separated by narrow fissure from supra-orbital margin and bearing small tooth visible dorsally; anterolateral margin with 5 similar evenly-spaced teeth beginning at level of sub-orbital tooth, curving posteriorly towards widest point of carapace; deeply marked branchial notch just behind widest point of carapace, bluntly rounded posterolateral tooth directed upwards, followed by strongly convergent margin to posterior carapace border; branchial groove deeply marked and connecting with deep cardiac grooves, encompassing area marked by pair of depressions and short ridges; short, shallow frontal groove extending posteriorly from median rostral tooth and pair of shallow depressions, separated by 2 small tubercles, behind first 2 anterolateral teeth. Third maxillipeds operculate, crista dentata armed with 9 or 10 strong corneous spines. Male chelipeds massive, merus trigonal, margins dentate; carpus surface smooth except for shallow groove on outer surface, inner distal margin with stout subacute tooth with 2 similar teeth on distal margin above propodal joint. Inner dorsal margin of propodus with 3 large sub-equal teeth, outer face smooth to finely granulate. Cheliped fingers stout, slightly down-curved, occlusal margins armed with 9 or 10 well developed, white, sub-acute teeth that interlock when closed leaving small basal gape. Occlusal teeth on right cheliped fingers larger than those on left: teeth on pollex gradually becoming smaller proximally, dactyl teeth of similar size except for proximal 3, being more widely spaced and stronger. Occlusal armature forming “crusher” teeth, but similar on both right and left cheliped (Fig 4). P2–3 shorter than chelipeds, margins smooth, dactyli ending in brown, sharp, curved, corneous tips and inner margins armed with 5 stout spines, decreasing in size proximally. P4 much shorter than P2–3, used for carrying camouflage over carapace, sub-chelate with strongly curved dactylus opposed by 2 large spines on propodal margin with 2 further spines on outer propodal margin at base of dactyl. P5 missing. Male abdomen with 6 free segments and telson, surface smooth, strong, sculptured median ridge on last segments 2–6. Lateral margins of segment 6 deeply indented to accommodate well developed tubercles on coxae of first walking legs providing abdominal locking mechanism. Telson triangular, posterior margin evenly rounded. Uropod plates at articulation between telson and segment 6, not visible dorsally. Remarks. Various incomplete descriptions of A. octodentata have been published (Haswell 1882; Baker 1907; Rathbun 1923a; Hale 1925, 1927). These accounts are not all in agreement so we present a more detailed description based on the largest specimen available to us (WAM C6517, male, 91.3 × 74.9 mm). The morphology of A. octodentata changes as it grows larger. Juveniles have a carapace width/length ratio of around 0.9, reaching 1.0 at maturity and around 1.2 in the largest crabs (compare Figs 5 and 7 herein). During growth, the lateral margin of the carapace becomes more convex, as a result of carapace widening and the number of teeth increases from 3 to 5. The front (orbital-rostral area) becomes proportionally smaller and teeth (including the post-orbital tooth) become more prominent (see Hale 1925: text figs. 1–5; Fig. 5). This species has large eggs (1.9 mm diam.) that give rise to juvenile crabs, brooded by the female. Distribution.

Ritchie, WAMSI Survey 4 Lynher Bank, 01-11-2016: female 18.8 × 19.1 mm. Description. Carapace as wide as long, covered by short tomentum, moderately convex, branchial and cardiac grooves distinct. Anterior half of carapace sparsely covered by low rounded tubercles, irregular in distribution and density. Rostral, orbital and anterolateral teeth are distinctive in being blunt and flattened. Some teeth also few low rounded granules. Rostrum tridentate, lateral teeth prominent, median tooth much smaller, strongly deflexed and barely visible dorsally. Short frontal groove extends backward from median tooth. Supraorbital and post-orbital teeth strong. Suborbital margin has 2 blunt teeth, larger tooth easily visible dorsally between supra- and postorbital teeth. Subhepatic area with scattered low rounded tubercles, largest visible dorsally between postorbital and first anterolateral teeth. Outer face of third maxillipeds also tuberculate. Anterolateral carapace margin convex, with 3 teeth decreasing in size posteriorly; smaller subacute posterolateral tooth marks branchial groove. Chelipeds and first 2 pairs of legs thickly covered with short coarse setae and tubercles similar to carapace. Cheliped fingers gaping armed with 6 or 7 teeth only last 3 interlocking. First and second legs slightly shorter than cheliped, inner margins of dactyli with 4 spines increasing in size distally. Fourth and fifth legs sub-dorsal, shorter, third pair shortest; dactylus of fourth leg with 2 strong propodal spines opposing and 3 spines on outer margin at base of dactyl; dactylus of third leg opposed by 2 strong spines with 2 spines on outer margin. Surface of abdominal segments tuberculate, freely moveable, abdomen fringed with longer setae; uropod plates visible externally locking in front of tubercles on coxae of first legs in males; posterior margin of telson concave in males, convex in females. Female sternal sutures 7/8 convergent ending apart on low rounded transverse ridge between chelipeds. Remarks. Examination of the lectotype of “ Dromidiopsis michaelseni Balss, 1935 ” shows that it is referable to “ Dromia nodipes Lamarck, 1818 ”, confirming the opinion of McLay (1993). The figure of D. michaelseni provided by Balss (1935: fig. 1) is not a very accurate representation of the holotype specimen collected by the Hamburg Museum Expedition. While the figured CW/CL ratio is similar to the lectotype, the outline of the carapace is much distorted by anterior half being narrowed and the posterior half widened as though the crab was viewed from a posterior perspective, thereby stretching the front. However, the size and arrangement of the anterolateral teeth match the lectotype. This has led to identification problems, perhaps explaining why Balss’ species has never been reported subsequently. Hale’s (1927: fig. 110) labelled “ Petalomera depressa Baker, 1907) shows a specimen of Fultodromia nodipes (Lamarck, 1818).

Lamarckdromia globosa. — Guinot & Tavares, 2003: 70 (in part). Type material. Lectotype: MNHN-B22033, male, CL 21.1 mm, damaged, dry, locality unknown. Description. Carapace globose, smooth, finely punctate, covered by short tomentum of thick plumose setae, rostrum tridentate, teeth similar median tooth slightly longer; supraorbital margin armed with pointed tooth, suborbital margin triangular, with slightly protruding tooth. Anterolateral carapace margin armed with prominent pointed tooth at widest point, below sub-orbital level, dividing it into and anterior concave part (hepatic region) and convex posterior section (branchial region). Hepatic region concave with blunt ventral lobe, at level of buccal frame corner, connected by concave margin to the anterolateral tooth. Branchial region interrupted by indistinct tooth at branchial groove margin continuing almost directly posteriorly (apparently not convergent towards the middle). Pair of “epigastric” (frontal) lobes protruding slightly, separated by weak frontal groove and branchial groove present. Milne Edwards (1837) described legs as large and very short; those of last pair almost as large as third pair. Dorsal margin of cheliped propodus with 3 or 4 small blunt proximal tubercles, with perhaps couple of smaller granules beside, remaining surface smooth; margins of movable and fixed fingers dentate, length of fingers approximately same as palm. Remarks. Complete description of the type, as far as possible, is included here because it has not been written before. Only a few recognizable dry fragments of the type specimen remain, but a composite description can be made from the observations of those who examined it in its more intact state (Lamarck 1818; Milne Edwards 1837; De Man 1887: pl. 18, fig. 1A, B) and our own observations of the fragments. Figure 24A–E includes De Man’s drawings and photographs of the male lectotype. The drawings accurately depict the recognizable fragments of the type and depict the same two intact pieces that we found and photographed (Fig. 24A–C). There are no figures of the intact animal, which may imply that when De Man examined the crab, it was already fragmented. Milne Edwards (1837) mentions the branchial grooves, but does not describe them, and he does not describe any other carapace features such as the cardiac grooves. Distribution. Unknown.

Description, Carapace width similar to carapace length in small specimens, ranging up to approx. 1.1 × cl in adults. Surface smooth, strongly convex, covered by short setae with fringe of longer setae across anterior margin. Frontal area steeply vaulted, short median groove from rostrum separates pair of gentle epigastric swellings; frontal fringe following edge of vault. Branchial groove deeply marked; mid-way on anterior side with pair of deep pits; groove connecting with deep lateral cardiac groove; anterior cardiac border marked by shallow lunate groove; intestinal area, posterior to cardiac area, deeply sculptured with ridges arranged in face-like manner; posterior carapace margin deeply concave. Rostrum tridentate, teeth well developed, sub-acute, similar size, lateral teeth directed horizontally, median tooth on lower level, slightly deflexed. Supraorbital tooth small blunt, postorbital tooth similar, suborbital margin with prominent blunt tooth visible dorsally between supra- and postorbital teeth. Anterolateral carapace margin obtuse, slightly convex followed by concave section ending at widest point, shoulder-like without distinct tooth; sub-hepatic area deeply excavated, slightly visible dorsally, lower margin prominent, obtuse, curving upward to meet shoulder. Posterior to widest point, carapace margin convex, interrupted by branchial groove without tooth.

Since revision of Dromidiopsis by McLay (1993) Dromidia excavata Stimpson, 1858 from Sydney Harbour (Port Jackson) has been known as Dromidiopsis globosa (Lamarck, 1818). Haswell (1882) had suggested that the “closest ally” of Dromia excavata was Dromia globosa Lamarck, 1818. The descriptions given by the authors of these species were brief, but De Man (1887: pl. 18 fig. 1A, B) provided an illustration of a presumed lectotype (MNHN-B22033, male damaged, locality unknown). Milne Edwards (1837) gives the size as CL = 21.1 mm. However, close comparison of our L. excavata specimens with De Man’s figure of the type in Paris (see below) show that they differ from L. globosa and are not synonymous as had been assumed. While the overall conformation of the anterior half of the carapace of L. globosa (the part illustrated by De Man, 1887) is similar, the sub-hepatic area is much more exposed in dorsal view and there is a strong anterolateral tooth near the widest point, a feature not shared by either of the Australian species dealt with herein (see 2). De Man’s figure of L. globosa also shows the right cheliped with 3 or 4 distinct tubercles along the dorsal margin of the propodus and a distinct tubercle on the superior distal corner of the carpus. Both of these characters are found in D. excavata but not in L. beagle sp. nov. Therefore, we conclude that there are three species of Lamarckdromia: L. beagle sp. nov., L. excavata and L. globosa, but only the first two are known to occur around Australia. The distribution of L. globosa is unknown. Hale (1927) said that in live L. excavata the carapace setae are pink. Distribution.

This species is very similar to Cryptodromia tuberculata (Fig. 13). Alcock (1900) proposed C. pileifera a sub-species of C. tuberculata, but in 1901 treated as a separate species. Comparison shows that in C. pileifera there are four evenly spaced anterolateral carapace teeth, with the last pair weaker (three teeth second and third separated by an edentate convex margin in C. tuberculata), the supraorbital margin is concave and weakly eave-like (supraorbital margin concave strongly eave-like), and the cheliped fingers are narrow, curved, gape slot-like (fingers stout, straighter, gape triangular). Both of these species have comparatively large eggs and C. pileifera only has a single larval stage (Tan et al. 1986). Cryptodromia tuberculata has even larger eggs (> 1.2 mm diameter) and so may well have an even shorter larval phase. Clutch size is correspondingly smaller, often with fewer than 10 eggs.

Cryptodromiopsis bullifera. — McLay, 1993: 189, fig. 17e. Material examined. Western Australia: WAM C42521, Ningaloo Marine Park, off Osprey Reef, 40.5– 40 m, 22°10’04”S, 113°50’39”E to 22°10.01”S, 113°50’40”E, 11-05-2006: male 7.7 × 8.2 mm (damaged). Description. Carapace as wide as long, evenly convex, covered in short tomentum, margins fringed with longer spatulate setae; branchial groove distinct but shallow; rostrum with 3 similar strong acute teeth, lateral teeth slightly divergent, median tooth on lower level; frontal groove extending posteriorly separating 2 low mounds; small, acute supraorbital tooth and strong postorbital and suborbital teeth visible dorsally; anterolateral margin distant from postorbital corner, shoulder-like, marking widest point, with strong tooth followed by smaller tooth close by; 2 tiny tubercles between postorbital corner and widest point, a little above the anterolateral margin; small posterolateral tooth behind branchial groove; subhepatic area with 2 prominent rounded smooth pearl-like tubercles, with similar tubercle on second antennal article; smaller tubercle on merus of third maxilliped. Edges of epistome shelf-like. Chelipeds well developed, covered in coarse setae (as with other pereopods), 3 prominent erect tubercles on carpus and similar distal tubercle on superior margin of propodus. Fingers white, gaping, occlusal margin with 6–7 small teeth. P2–3 shorter than chelipeds, distal border of carpus produced, dactylus long curved, bearing 5 small spines along inner margin. P4–5 legs slender, shorter than P2–3, P4 shortest, P5 subdorsal, dactylus short curved and opposed by single propodal spine. Female sternal grooves ending close together on elevated platform between bases of chelipeds. Male abdomen held in place by uropods between bases of first pair of walking legs, third to fifth segments with 3 median tubercles and flattened lateral tubercle on each side. Telson wider than long, apex rounded. Remarks. The small female specimen reported by McLay (1993) had sternal grooves ending close together on an elevated platform between the bases of the chelipeds. In species of Cryptodromia Stimpson, 1858, the sternal grooves are shorter, ending apart between the bases of P2. The main features used for establishing Baccadromia gen. nov. are the longer sternal grooves ending close together as well as the unusual facial ornamentation. Our male specimen has a damaged left rostral tooth and the right postorbital tooth is broken off, but otherwise intact. The distinctive features of this crab include the rather long and acute nature of the rostral teeth as well as the tubercles on the chelipeds and the pearl-like tubercles that adorn its “face”. These characteristic rounded tubercles are to be found on the sub-hepatic area, on the basal article of the antenna and on the merus of the third maxilliped. Together each group of four is reminiscent of a constellation of stars mirrored about the median plane. Their pearl-like shape is a reminder of the large pearl-like tubercles found on the fourth abdominal segment of the dynomenid, Acanthodromia spp. Distribution. Red Sea, East Africa, Madagascar, South Nilanda Atoll, Maldives Archipelago, Cinque Island (Andaman Sea) (type locality), Philippines, Japan, Chesterfield Ids.

Etymology. The specific name for this new species acknowledges the Dambimangari, traditional owners of Camden Sound, where the species was first discovered. It is a noun used in apposition. Description. Carapace as wide as long or slightly wider, weakly convex, weak frontal groove, cardiac area well defined, branchial groove marked; surface covered in low subacute scattered tubercles of different sizes with larger tubercle roughly behind supraorbital tooth, surface between them smooth. Rostrum strongly tridentate; subacute median tooth shorter than flattened lateral teeth but visible dorsally; supraorbital margin interrupted by strong blunt tooth, postorbital tooth absent, suborbital tooth not visible dorsally. Anterolateral carapace margin armed with 2 prominent flattened teeth, second tooth bifid, smaller blunt posterolateral tooth behind branchial groove; posterolateral margin convergent, occasionally with several smaller blunt tubercles; posterior carapace margin sinuous. Subhepatic area flat with pair of tubercles beneath anterolateral teeth and broken “saw-tooth”-like ridge extending from buccal corner, epistome plate-like. Female sternal grooves ending apart but in close proximity on elevated humps at either end of ridge lying between boundary between chelipeds and P2. When closed, telson lying directly over (in ventral view) termini of sternal grooves. Chelipeds and P2 and P3 elongate, not massive, sparse small rounded tubercles, dorsal distal borders of merus, carpus and propodus produced as prominent blunt lobes. Inner margins of P2 and P3 dactyli armed with 3 or 4 evenly spaced stout spines. Cheliped fingers flattened, gaping, with 7 or 8 small teeth. P4 and P5 both dorsal, P4 shortest, P5 reaching almost to second anterolateral tooth when extended anteriorly. P4 and P5 dactylus short stout acute bent into right-angle shape and twisted upwards at around 45°; opposed by single stout propodal spine. Abdomen strongly ornamented and sculptured, segments immobile. Female segments with large blunt tubercles tending to be arranged in pairs: medially with two adjacent pairs on first segment, becoming merged into single ridge on posterior segments; laterally with pair, one behind the other, becoming larger posteriorly. Telson triangular, tip rounded, basal width about twice length, centrally 2 pairs of small blunt tubercles, small angled ridge is suggestive of uropods often present in dromiids but these are absent here. Male abdomen ornamentation similar to that of females but tubercles much less prominent; telson trapezoidal in shape, length slightly more than half basal width, tip truncate posterior corners end in subacute lobes. Abdominal locking mechanism consisting of lateral projections from margins of penultimate segment fitting in front of tubercles on P2 coxae. Male G1 flattened, setose tube, G2 longer than G1, needle-like. Remarks. The major differences between Alainodromia dambimangari sp. nov. and A. timorensis are as follows: lateral rostral teeth broader (less flattened in A. timorensis); median rostral tooth prominent (deflexed less prominent); only second anterolateral tooth deeply bifid (both teeth bifid); frontal carapace surface covered in low subacute scattered tubercles of different sizes with one larger tubercle roughly behind supraorbital tooth (surface covered with scattered small tubercles but prominent row of five larger tubercles at level of first anterolateral tooth) (Fig. 1). McLay (1998) stated that the abdominal segments of the type male were “free”, but while there are sutures present between them, there is very little flexibility and the abdomen as a whole only articulates with the thorax. When specimens are preserved in formalin it can be difficult to determine whether inflexibility is a result of preservation or a natural condition. The present material allows us to show that in both males and females, segment immobility is the natural condition and that the abdomen has a largely fixed shape in both sexes articulating with the thorax. In males, the abdomen is approximately linear, retained by the abdominal locking mechanism, whereas in females, it is rounded, forming a brood chamber held closely against the sternum by musculature. The female abdomen does not have abdominal locking mechanism. The plesiomorphic condition in decapods is to have all segments free, but in Brachyura the ventrally folded abdomen requires some holding mechanism: segment immobility (resulting from fusion or ankylosis) or a locking mechanism are alternatives. Partial ankylosis of abdominal segments is a feature of species of Dromidiopsis Borradaile, 1900 and Lauridromia McLay, 1993. When describing Alainodromia timorensis McLay (1998) speculated that this species may carry pieces of sponge, but both P4 and P5 are dorsal in this genus, unlike most other dromiid genera where P4 is directed ventrally and P5 is sub-dorsal. In A. timorensis they both lie in the same horizontal plain so that their movements are only anterior/posterior, linked to the weakly convex shape of the carapace. The dactyli are unusual in being short, stout and bent into a right angle and oriented vertically at approximately 45° so that neither are directed ventrally as might be found in a sponge-carrying dromiid. They show closest resemblance to the P4 and P5 of Desmodromia McLay, 2001, which is a bivalve shell-carrier also found in northwest Australia (see McLay & Hosie 2012). Desmodromia has a more convex carapace and the P5 is subdorsal, whereas the P4 is directed ventrally and has been found with cockle shells. However, the P4 and P5 dactyli of Alainodromia dambimangari sp. nov. are opposed by a small propodal spine not found in Desmodromia. Both of these genera have distinctive lamellate anterolateral carapace margins, which may be related to the use of shells for camouflage. These structures would increase the amount of carapace surface in contact with the inner surface of the shell. The carapace of species of Alainodromia is only weakly convex, so it may utilize more flattened shells. The ovigerous female of A. dambimangari sp. nov. had approximately 100 large eggs of diameter 1.5 mm. The small brood-large eggs strategy is a feature shared with Desmodromia tranterae whose females have been recorded with ~ 20 eggs, 0.8–0.9 mm diameter. The difference in brood size is probably a reflection of female size, but egg size of A. dambimangari is considerably larger, having 4.7 × the volume of those of Desmodromia tranterae. On this basis A. dambimangari possibly has direct development and D. tranterae abbreviated development. Direct or abbreviated development is apparently a feature of the Australian dromiid crab fauna (see McLay 1993; McLay et al. 2001; Morgan 1987). The type female of A. dambimangari had a tubiculous polychaete, 3 mm diameter, attached to the left third maxilliped suggesting that it may not have moulted recently. The other species in the genus, Alainodromia timorensis has been collected from 27–44 m in the Timor Sea. Distribution. Known only from northwestern Australia.

Carapace longer than wide, oblong-shaped; evenly convex; branchial groove shallow; short dense tomentum; rostrum short, tridentate, median tooth small not visible dorsally; strong supraorbital and suborbital teeth; concave area immediately behind orbit shelf-like; anterolateral margin beginning at orbital level, without teeth. Cheliped without epipod. Female thoracic sternal sutures 7/8 ending together on central raised ridge between bases of P2, apertures directed anteriorly. Remarks. Lewindromia unidentata was first recorded from Australia as Cryptodromia unilobata Campbell & Stephenson, 1970, having been found in Moreton Bay Queensland. Guinot & Tavares (2003) erected the monotypic genus Lewindromia to accommodate Dromia unidentata Rüppell, 1830, because it has several distinctive features. They compared L. unidentata with several sponge carrying genera, but it is more constructive to compare it with species that have an intimate association with ascidians, such as Ascidiophilus Richters, 1880 because L. unidentata often uses ascidians and soft corals for shelter. The life style of Ascidiophilus caphyraeformis Richters, 1880 is described by Gordon (1950). This species lives almost totally enclosed in an ascidian or other soft-bodied host. Lewindromia unidentata has an elongate body with a smooth surface, long P5 to carry its host and female thoracic sternal grooves ending close together between the P2s as found in A. caphyraeformis. However, in Ascidiophilus caphyraeformis the rostrum is strongly projecting forming a triangular extension, entire and supported beneath by a keel, whereas in L. unidentata it is weakly tridentate, a condition more typical of sponge-carrying dromiid crabs. In A. caphyraeformis the rostrum and superior orbital border are continuous whereas in L. unidentata the border is interrupted by a blunt preorbital tooth. In A. caphyraeformis the orbits are exposed, but in L. unidentata they are protected and have a suborbital tooth. The body shape also differs: in A. caphyraeformis the body is divided into 2 unequal sections by deep branchial grooves whereas in L. unidentata these grooves are much weaker and the carapace is more or less ovoid in shape. In L. unidentata uropods are present as dorsal plates (concealed) whereas they are absent in A. caphyraeformis. Lewindromia unidentata has a very hirsute body, densely covered by long setae, whereas A. caphyraeformis only has a short tomentum. In many respects the morphology of L. unidentata is intermediate between the sponge-carrying habit and more specialized ascidian-carrying habit found in A. caphyraeformis. Distribution. Red Sea, Indian Ocean, Singapore, Japan, Philippines, Queensland, New Caledonia, Kermadec Islands (New Zealand), Tonga, Hawaii and Easter Island.
