Carapace wider than long, maximal width at fourth anterolateral tooth, minutely granular near anterolateral margins, coarsely granular posterolaterally; mesogastric, cardiac, intestinal regions smooth, poorly defined by faint grooves; hepatic region little more distinct. Ventrally, granulation neatly more distinct on suborbital, subhepatic and branchiostegal regions. Pterygostomian region coarsely granular near moulting suture, minutely granular near mxp3, with dense, coarse granules on low crest (scrapper) above inhalant channel. Branchiostegal margin lined with granules, above and, along margin row of strong granules. Fronto-orbital width little more than half of maximal width of carapace; frontal margin V-shaped, with medial cleft; frontal margin smooth; just behind frontal margin inconspicuous scattered granules and pits. Supraorbital margin interrupted by 2 small notches, margin serrated with low, acute granules, serration coarsest in lateral half, continued to outer orbital tooth (first anterolateral). Inner supraorbital tooth separated from front by wide, shallow gap, low, blunt; outer orbital tooth very low, lobe-like. Suborbital margin lined with small granules, mesially with broadly triangular tooth directed toward front, laterally with broad lobe, V-shape wide cleft between suborbital lateral lobe and outer orbital tooth. Anterolateral margin projecting in 5 distinctly granular teeth (outer orbital included), increasing successively in size posteriorly from first to fourth tooth: second tooth triangular, blunt; third very strong, broad triangular; fourth spiniform, sharp; fifth (last anterolateral tooth) very small but distinct, acute. Gap between anterolateral teeth 3

3. Posterolateral margin well defined and rather straight behind last anterolateral tooth, poorly defined posteriorly, about as long as anterolateral margin. Limit between epistome, endostome well defined, forming pronounced, sinuous lip, interrupted by 2 V-shaped, deep notches, one at each side of deep mesial notch. Ocular peduncle cylindrical, very scattered granular dorsally, freely movable, thick, constricted subproximally, fully retractable into orbital cavity; cornea occupying much less than half-length of whole eye; ommatidia dark, poorly recognizable. Antennules prominent; proximal article thickest laterally, with semicircular, transverse row of granules; second article smooth, elongated, subcylindrical, articulated with proximal article at mesial end of antennular fossa; third article nearly equal in length to second, swollen distally, tapered to proximal articulation with second article, terminally with long marginal setae at either side of dorsal flagellum. Antennal article 2+3 immovable, filling orbital gap; articles 4, 5 freely movable, subcylindrical. Thoracic sternum minutely granular anteriorly, granulation stronger posteriorly; sterno-abdominal cavity deep, slightly granular anteriorly, lateral margins with scattered granules, more discernible posteriorly. Abdominal locking system functional in male, thoracic sternal button small, directed forward, placed about mid-length between thoracic sternal sutures 4/5 and 5/6. Third maxillipeds inserted wide apart from each other; ischium smooth, pitted, with faint longitudinal furrow, mesial margin granular; merus distinctly shorter than ischium, evenly granular; palp smooth. Chelipeds heterochelous, right P1 strongest. Merus of major P1 trigonal, dorsal margin with strong, blunt, subdistal tooth; surfaces evenly covered with fine granules, granulation strongest dorsally. Carpus with acute spine on inner margin; surfaces finely granular, granules stronger anteriorly and ventrolaterally. Propodus stout, surfaces minutely granular, granules forming reticular patterns. Fingers black, closing terminally only; cutting edges bluntly dentate, teeth becoming more coalescent posteriorly; teeth stronger on fixed finger. Minor cheliped similar to major cheliped except for its slender fingers. Ambulatory legs (P2–P5 detached from body) long, slender, similar to each other. Meri P2–P5 meri spinous dorsally, granular ventrally. P2

P5 carpi with dorso-lateral, longitudinal, smooth depression, on each side a row of distinct granules; ventral surface smooth. P2–P5 propodi with scattered granular proximally. P2–P5 dactyli corneous-tipped, 6 longitudinal rows of dense, long setae, 2 dorsal, 2 ventral, 2 lateral. Abdomen of 4 somites and telson; abdominal somites 1–2 markedly short, somite 1 much broader than somite 2; somites 3–5 fused together; abdominal somite 3 expanded laterally, almost completely covering penis; abdominal suture 3/4 faint, still recognizable; suture 4/5 indistinct, its position indicated laterally only by faint cleft. Telson semicircular. G1 distinctly curved outward, just reaching to thoracic sternal suture 4/5. G2 very short, just reaching to sternal suture 7/8.

probably produce sound by stridulation. Both species have an ischial ridge on the mesial side of the right and left chelipeds (par stridens, see Guinot-Dumortier & Dumortier 1960) that rubs against a scrapper (plectrum) on the carapace, a curved tuberculate edge located above the inhalant water opening. The chelipeds basis-ischium is fused together into a single article providing additional leverage for the rasping movement.
