Shield (Fig. 2a) broader than long; dorsal surface weakly calcified medially; rostrum triangular, with low dorsal ridge; anterior margins straight; lateral projections broadly rounded, often nearly obsolete; ventrolateral margin unarmed; posterior margin broadly rounded. Ocular peduncles more than half length of shield; ocular acicles subtriangular, terminating in spine (rarely bifid on one side); corneae slightly dilated. Sternite of 3rd maxillipeds with spine on each side of midline. Epistomial spine straight, often absent. Antennular peduncle exceeding distal margin of corneae by full length of ultimate segment. Antennal peduncle at most slightly exceeding distal margin of cornea; 4th segment unarmed; 3rd segment with strong ventromesial distal spine; 2nd segment with dorsolateral distal angle produced, terminating in strong spine with 3 small spines dorsally; acicles reaching at most distal margin of corneae, mesial margin armed with 9 to 12 spines; flagellum with few setae &lt;1 flagellar article in length. Chelipeds markedly dissimilar, with numerous tufts of setae (not shown in Fig. 3a,b) obscuring surfaces. Right cheliped (Fig. 3b) with chela varying from 1.5 to more than twice as long as broad in larger individuals; fingers weakly curved ventromesially, dactyl with weakly concave ventromesial face; dorsal and ventral faces of palm unarmed, smooth except for tufts of setae; mesial and lateral faces ofpalm rounded, with lateral and dorsomesial rows of spines; carpus with numerous small tubercles or spines on dorsal surface. Left cheliped (Fig. 3a) with chela unarmed, well calcified; carpus with dorsodistal spine, and dorsal row of 2 to 4 well-spaced spines. Ambulatory legs (Fig. 2b,c) exceeding tip of extended right cheliped; dactyl about twice as long as propodus, with ventromesial irregular row of 20 to 25 minute corneous spines, dorsal row of long setae, and 3 dorsomesial oblique rows of long setae distally; carpus with small dorsodistal spine; ischium and merus of 2nd pereopod with row of few small tubercles or spines. Anterior lobe of sternite of 3rd pereopods unarmed or with 1 marginal spine, setose. Fourth pereopod with dactyl terminating in corneous claw; propodal rasp of adults consisting of 4 to 6 rows of ovate scales (Fig. 2d), and of juveniles (SL &lt;5.5 mm) of 1 or 2 rows of ovate scales (Fig. 6g). Uropods and telson (Fig. 4 a­ d) markedly asymmetrical; telson with weak transverse suture separating anterior and posterior lobes, dorsal surface with low blister-like tubercles; posterior lobes separated by V-shaped cleft, terminal margins armed with often long corneous spines, spines on left side strongly curved laterally, usually much longer in females than in males (Fig. 4c,d). Male 1st gonopods (Fig. 4e) each with concave distal lobe; 2nd gonopods (Fig. 4t) each with distal segment nearly flat, rounded distally, often with rudimentary exopod. Females with vestigial right 2nd pleopod. <b>Habitat and symbiotic associations.</b> Lives associated with an actinian (Fig. 5a) that secretes a carcinoecium similar to that produced by species of <i>Stylabates</i> (see Fautin Dunn <i>et al.,</i> 1980; Fautin Dunn &amp; Liberman, 1983; Fautin, 1987). <b>Distribution.</b> Indo Pacific: Zanzibar; Indonesia; Philippines; and Australia. Depth: 267 to 794 m. <b>Remarks.</b> As pointed out by the De Saint Laurent (1972: 106), specimens of this species can attain a large size. The largest specimen measured during the present study has a SL of 26.0 mm, exceeding all other specimens of <i>Sympagurus</i> species. This species is among the most common of <i>Sympagurus</i> found in Australia but apparently is confined to the north. <b>Comparison ofjuveniles and adults.</b> Juvenile specimens of S. <i>brevipes</i> that are as large or larger than adult specimens of other <i>Sympagurus</i> species are frequently encountered. As in other species in the genus, such as S. <i>dimarphus</i> (see Lemaitre &amp; McLaughlin, 1992), the morphology of juveniles of S. <i>brevipes</i> can be quite different from that of adults. The most important differences between juveniles and adults of this species are summarised below. The ocular peduncles of juveniles are subequal in width throughout their length (Fig. 6a); the peduncles of adults are medially constricted (Fig. 2a). The antennal acicle of juveniles is armed mesially with usually four weak spines (Fig. 6b); the acicle of adults is armed with nine to 12 spines. Chelipeds ofjuveniles, when extended, have nearly the same length, the spines are weak, not numerous (Fig. 6c,d), and pilosity does not obscure the surfaces; chelipeds of adults are markedly different in distal extension, spination is strong, and pilosity is dense, obscuring the surfaces. The meri of the 2nd and 3rd pereopod in juveniles (Fig. 6e,t) are not as broad as those of adults (Fig. 2b). In juveniles, the propodal rasp of the 4th pereopod has two rows of scales (Fig. 6g), smaller specimens (SL &lt;3.5 mm) only one row; the rasp of adults has four or five rows (Fig. 2d). The 2nd to 5th pleopods ofjuveniles are paired, asymmetrical, the left biramous with a short endopod, the right uniramous (Fig. 6 h-k). Juvenile males exhibit rudimentary paired 1st gonopods. Adults have gonopods or pleopods as indicated in the diagnosis. The terminal margin of the posterior lobes of the telson of juveniles are armed with few small spines (8, left lobe; 5, right lobe; Fig. 61); the terminal margins of adults are armed with many spines (20+ on left lobe, 8 on right lobe). The vestigial pleurobranch on the last thoracic somite is occasionally absent in small juveniles (SL &lt;3.5 mm), whereas the pleurobranch is invariably present in adult specimens.
