No full textNeopalicus halihali n. sp. (Figs. 4, 5) Holotype. Ovigerous female, 5.5 mm × 6.2 mm, off southwestern Maui, dredged, 91 m (300 ft), Mike Severns & Shirley Speer coll., 26.10.2112 (USNM 121140). Description of female holotype. Carapace subquadrate (Figs. 4, 5a), slightly wider than long (cl/cw = 0.9); small size; dorsal surface covered with fine granules; horizontal row of 6 large, low, granular bosses across carapace posterior to conspicuously elevated mesogastric region; bosses with numerous short plumose setae. Confluence of branchial, mesogastric regions depressed; depression along median portion of frontal region. Short, bilobed rostrum. Frontal border of carapace lateral to rostrum with single, rounded frontal lobe slightly salient anteriorly. Margin between frontal lobes, supraorbital border sinuous, ending in sharp angle, forming deep Vshaped fissure before supraorbital border. Supraorbital border with 2 rounded lobes (right outer lobe missing), inner lobe slightly larger than outer lobe. Postorbital angles short, rounded, not extending beyond dorsal border of retracted eye peduncle, nearly straight. Anterolateral border of carapace (Fig. 5a) with 3 large, salient, triangular teeth with acute tips, plus short, blunt fourth teeth; teeth decrease in size posteriorly, first (anteriormost) largest, most conspicuous. Posterior border with row of short, elongated tubercles, few plumose setae; 2 rows of rounded tubercles anterior to border. Basal antennal article (Fig. 5b) slender, rectangular, with wide, long, wing-like extension on outer margin; flagellum long, with few short, simple setae. Epistome dorso-ventrally expanded, forming broad, semicircular, nearly flat median lobe; 2 acute teeth on median margin. Ocular peduncle (basophthalmite) (Fig. 5b) thick, with 3 dorsal, triangular, crest-like tubercles, median tubercle largest, rounded tubercle on distal extension of peduncle nearly encircled by cornea. Cornea dorso-ventrally depressed, wider than base of ocular peduncle. Suborbital border (Fig. 5b) with 2 lobes; short, rounded inner lobe, wider, slightly convex, rounded outer lobe with microscopically dented margin. Pterygostomial lobes projecting ventrally, forming flat, rounded structure posterior to inner suborbital lobe. Inner margins of third maxilliped ischium straight; surface granular, upper margin rounded. Merus much narrower than ischium, straight-edged. Chelipeds (P1) (Fig. 4) slightly unequal; propodus of larger cheliped slightly higher, thicker than smaller cheliped, few plumose setae. Dorsal, outer margin of cheliped propodus with crest having 2 high, rounded tubercles plus several smaller tubercles, denticles; inner surface bare of setae; fingers slender, with cutting edges or rounded teeth. Carpus short, dorsal, outer margin with conspicuous, high, rounded tubercle; merus slender, smooth. Ambulatory legs (P2–P4) (Figs. 4a, 5c) dorsoventrally flattened; P2 shorter than P3, P4; P3 nearly as long as P4. Upper, lower margins of P3, P4 meri with several short, tooth-like tubercles; distalmost upper margins angular, without distinctive tubercle. Outer margins of P3, P4 carpi with 2 or 3 triangular, tooth-like tubercles, distalmost largest. Outer margins of P3, P4 propodi smooth, inner margins armed with 6 or 7 short teeth, low carina along middle portion. P3, P4 dactyli (Fig. 5c) with long, inner margins armed with 5 or 6 short teeth, low carina along middle portion. Few long plumose setae on inner, outer margins of P2–P4 meri, distal portion of carpi; numerous long plumose setae on inner surface of propodi, dactyli. P5 (Fig. 4) reduced (0.8 cl), dorsal to P4; merus slender, with microscopic tubercles along inner margin, scattered plumose setae; propodus with 3 long spines along inner margin; dactylus with microscopic tubercles along margins, acuminate tip. Abdomen with all somites freely articulating, outer surface smooth without transversal ridges. Vulva small, on thoracic sternite 6 but displaced to median plate of sternum. Male unknown. Etymology. Reduplication for emphasis of hali, Hawaiian for “to transport,” in reference to the carrying behavior recorded in the new species. The name is treated as a Latin noun in apposition. Remarks. Neopalicus halihali n. sp. is assigned to Neopalicus Moosa & Serène, 1981, as re-described by Castro (2000: 548). Neopalicus until now consisted of three Indo-West Pacific species: N. contractus (Rathbun, 1902), N. jukesii (White, 1847), and N. simulus Castro, 2010. The new species shares with its congeners a subquadrate carapace with horizontal rows of large and low bosses on its dorsal surface; large, spherical (not rheniform) eyes with ocular peduncles each having three dorsal tubercles, supraorbital borders with two rounded lobes; basal antennal article with a flattened expansion; dorso-ventrally flattened, expanded epistome, without an apparent median fissure; P2–P4 with dorso-ventrally flattened (not filiform) carpi, propodi, and dactyli; spinous posterior margins of the P5 propodus; and abdomen of adult females with all somites freely articulating (see Castro 2000: 548, tab. 1). There are nevertheless differences between N. halihali n. sp. and its three congeners: presence of three triangular teeth along each anterolateral border (Fig. 5a) instead of two large truncated teeth (Castro 2000: fig. 39; 2010: fig. 1A, B), presence of a small fourth anterolateral tooth absent in congeners, P3 and P4 propodi with simple margins (Fig. 4a) without a wide and convex extension (Castro 2000: fig. 39; 2010: fig. 1A, B), P2 and P3 dactyli posterior margins dentate (Fig. 5c) instead of entire, and female abdomen with smooth somites instead of the presence of ridges. The rostrum is bilobed as in N. contractus and N. jukesii (Castro 2000: fig. 39) but different from the simple rostrum of N. simulus (Castro 2010: fig. 1A, B). The suborbital border consists of two slightly convex lobes (Fig. 5b), similar to N. simulus (Castro 2010: fig 1C), but different from the triangular lobes of the other two congeners (Castro 2000: fig. 40). Neopalicus halihali n. sp. is closest to N. simulus, another small-size species known only from French Polynesia. In addition to the similarities and differences indicated above, the new species differs from N. simulus by having a row of low, elongated tubercles on the posterior border of the carapace (Fig. 5a) (short, rounded tubercles, one at each end, plus three median tubercles in N. simulus); basal antennal article with wide, long outer extension (Fig. 5b) (short, wing-like extension in N. simulus; Castro 2010: fig. 1C); outer margin of cheliped propodus with a conspicuous crest consisting of two high, rounded tubercles plus several smaller tubercles and denticles (Fig. 4a) (two high, rounded tubercles and no crest in N. simulus; Castro 2010: fig. 1A); dorsal, outer margin of cheliped carpus with a conspicuous, high, rounded tubercle (Fig. 4a) (smooth in N. simulus; Castro 2010: fig. 1A); outer margins of P3 and P4 carpi with tooth-like tubercles and denticles (Fig. 4a), inner margin dentate (outer margin with rounded tubercles, smooth inner margin in N. simulus; Castro 2010: fig. 1A); outer margins of P4 propodi with microscopic tubercles (entire, with wide, convex, carina-like extension in N. simulus); inner margins of P3 and P4 dactyli dentate (Fig. 5c) (entire in N. simulus; Castro 2010: fig. 1A); and smooth female abdomen, without transversal ridges (transversal ridge along each somite 1–4, less pronounced in other somites in N. simulus). The male of the new species remains unknown. Males of the three congeners are characterized by having elongated abdomens with all somites freely articulating, and a long and slender G1 with sinuous basal portion but very different terminal portions (see Castro 2000: fig. 41a–c for N. contractus and N. jukesii; 2010: fig. 1D for N. simulus). Although some of the differences between the chelipeds of the new species and N. simulus may be sex related, the characters of the female holotype alone are distinctive enough to warrant its description as a separate species of Neopalicus. Neopalicus contractus is known from across the Indian (type locality: Maldives) and western Pacific oceans (Philippines to New Caledonia and the Marshall Islands). The distribution of N. jukesii (type locality: Queensland, Australia) is close to that of N. contractus except that N. jukesii is also known from the Red Sea and Japan but not from the central Pacific (Castro 2000: fig. 49, 588). Both N. simulus and N. halihali n. sp. are known only from the eastern limits of the Indo-West Pacific region, N. simulus from the Austral Islands, French Polynesia, and N. halihali n. sp. from the Hawaiian Islands. Neopalicus contractus and N. jukesii have been collected, sometimes sympatrically, in coarse sand near coral reefs at depths of 10–146 m (see Castro 2000: 587), N. simulus from rocky bottoms containing coral rubble at 90–200 m (one specimen from 360–840 m; Castro 2010: 78), and N. halihali n. sp. from coral rubble at 91 m. The live holotype of the new species was photographed carrying what appears to be a dead fragment of a filamentous red alga (Fig. 4b). Two other species of palicids have been recorded as carrying fragments of sediment or seaweeds with their reduced, dorsally-placed P5, a behavior known as carrying behavior (see Guinot et al. 2013: 246, fig. 54). This behaviour is most probably widespread, even universal, among palicids. The new species represents the fourth species of Palicidae known from the Hawaiian Islands (see Castro 2011: 10, 54).Published as part of Castro, Peter & Naruse, Tohru, 2014, New species of Latreillopsis Henderson, 1888 (Brachyura: Homolidae) and Neopalicus Moosa & Serène, 1981 (Brachyura: Palicidae) from the Hawaiian Islands, pp. 169-180 in Zootaxa 3764 (2) on pages 175-179, DOI: 10.11646/zootaxa.3764.2.4, http://zenodo.org/record/504561

DISTRIBUTION. — Western Atlantic along the west coast of Africa from Western Sahara and Cabo Verde Is to Angola. Depth: 200- 586 m. REMARKS Capart (1951: 172) described Goneplax barnardi n. comb. under Carcinoplax on account of the shape of the carapace, the relatively short eye peduncles, and "the other characteristics of the genus". He agreed that Carcinoplax was nevertheless close to Goneplax and that the male first pleopods of his new species were difficult to be used as a diagnostic character. In contrast to Carcinoplax, G. barnardi n. comb. has longer eye peduncles, the dorsal margins of the ambulatory leg (P2-P5) meri are armed with an acute distal tooth (although present in C. spinosissima Rathbun, 1914), and the dactyli are slender and have a carina on each side. Sakai (1976: 531, as Carcinoplax barnardi) mentioned that the species "seems to belong to Psopheticus, near P. insignis " but without giving any explanations. Goneplax barnardi n. comb. may be distinguished from G. rhomboides and G. clevai, which are also found along the West African coast, by the rounded anterolateral borders of its carapace and the presence of conspicuous tubercles on the subhepatic region (Fig. 27B). The borders are straight or nearly straight and the subhepatic region lacks large tubercles in G. rhomboides (Fig. 27A) and G. clevai (see Guinot 1989: fig. 45, as [Carcinoplax] barnardi; Guinot & Castro 2007: figs 1-3). Also diagnostic is the length of its eye peduncles. They are much shorter in G. barnardi n. comb. (0.4 front width; Fig. 27B) than in G. rhomboides, where it is as long as or slightly longer than the front width (Fig. 27A), or in G. clevai, where they are slightly shorter than the front width (0.8 front width). There are also probable differences in colour. Goneplax barnardi n. comb. was described as "rose bistre" (dark-brown pink) (Capart 1951: 172), while G. rhomboides is known to have a "yellow to pale red, sometimes fringed with violet" carapace and "yellow to orange" chelipeds and ambulatory legs (Ingle 1980: 109). Goneplax clevai was described by Barnard (1950: 285, as G. angulata) as "pale pink, or salmon, or pinky-cream, carapace and chelipeds more or less vermiculate or mottled". A freshly preserved specimen had irregular, purple-pink reticulations on the anterior portion of the carapace; the dorsal surfaces of the chelipeds and eye peduncles were light purplepink (see Guinot & Castro 2007: fig. 2B).Published as part of Castro, Peter, 2007, A reappraisal of the family Goneplacidae MacLeay, 1838 (Crustacea, Decapoda, Brachyura) and revision of the subfamily Goneplacinae, with the description of 10 new genera and 18 new species, pp. 609-774 in Zoosystema 29 (4) on pages 689-690, DOI: 10.5281/zenodo.452556

ETYMOLOGY. — From simulus, diminutive of simus, Latin for “flat” or “pug nosed,” in reference to the short, rounded, non-bilobed rostrum that is diagnostic of the species. DISTRIBUTION. — Known only from the Austral Is, French Polynesia. Depth: 90-200 m and from a station (CP 1923) 360-840 m deep. DESCRIPTION Carapace (Fig. 1A, B) subquadrate, nearly as wide as long (cw/cl = 1.0-1.3); dorsal surface covered with fine granules, horizontal rows of large, low granular bosses.Confluence of branchial, mesogastric regions depressed; depression along median portion of frontal region. Short, simple (non-bilobed) rostrum. Anterolateral borders of carapace each with 2 large, truncated teeth, first (anteriormost) largest, most conspicuous. Posterior border with short, rounded tubercles (one at each end, 3 median), setae absent. Frontal border of carapace with single, rounded lobe. Borders between frontal lobe, supraorbital borders sinuous, ending in sharp angle, forming deep V-shaped fissure before supraorbital border (Fig. 1A, B). Supraorbital borders each with 2 rounded lobes. Postorbital angles short, not extending beyond dorsal border of retracted eye, nearly straight. Cornea of eyes dorso-ventrally depressed, wider than base of eye peduncle. Each peduncle with 3 dorsal tubercles: anterior, distal, crest-like (depressed); median tubercle smaller than other 2 tubercles; large, rounded tubercle on distal extension nearly encircled by cornea. Suborbital borders (Fig. 1C) slightly convex; smooth. Pterygostomial lobes project ventrally, forming flat, rounded structure posterior to each inner suborbital lobe. Basal antennal article (Fig. 1C) slender, rectangular, with short, wing-like extension; flagellum long, with few, simple setae. Epistome expanded dorso-ventrally, forming broad, semicircular, nearly flat surface; thin, carina-like process across median portion with two median teeth. Inner margins of ischium of third maxillipeds straight; surface coarsely granular, upper margins rounded. Merus much narrower than ischium; straight-edged. Chelipeds (P1) unequal in both sexes; propodus of larger cheliped of males much higher, thicker than smaller cheliped (Fig. 1A). Dorsal, outer margins of cheliped propodus with 2 high, rounded tubercles (except larger cheliped of males, which is smooth), inner surface with dense clusters of plumose setae in males, bare in females; fingers with cutting edges or rounded teeth. Carpus short, smooth; meri slender, smooth. Ambulatory legs (P2-P4) dorso-ventrally flattened; P2 shorter than P3, P4; P3 nearly as long as P4 (Fig. 1A). Upper, lower margins of merus with short rounded tubercles; distalmost tubercle on each anterior margin wider at base, higher, directed distally. Anterior margins of carpus with tubercles. Dorsal surface of P3, P4 propodi, dactyli with many plumose setae; margins of P3, P4 propodi entire, anterior margins each with wide, convex carina-like extension; dactyli long, slender, entire margins. P5 short (0.7-0.9 cl), dorsal to P4 (Fig. 1A); merus slender, with microscopic tubercles along posterior margins, scattered simple setae; propodus with 4 or 5 short spines along posterior margin; dactylus with 3 or 4 short spines along posterior margin, terminal pointed tooth. Abdomen of mature males elongated, with all somites freely articulating, smooth, without transverse ridges. Penis showing coxo-sternal condition. G1 (Fig. 1D) long, slender, with sinuous basal part; distal part with small teeth, simple, uniramous apex. G2 much shorter than G1. Abdomen of mature females with all somites freely articulating.Transversal ridge along each somite 1-4, less pronounced in somite 5. Vulvae small, round, with simple margins, on thoracic sternite 6 but displaced to median plate of sternum. REMARKS The new species clearly belongs to Neopalicus as redescribed by Castro (2000: 548). The genus until now consisted of two species, N. contractus (Rathbun, 1902) and N. jukesii (White, 1847). Neopalicus simulus n. sp. shares with these two species a subquadrate carapace with horizontal rows of large and low bosses on its dorsal surface; two large truncated teeth along each anterolateral border; large eyes with eye peduncles each having three dorsal tubercles; supraorbital borders with two rounded lobes; basal antennal article with a short, wing-like expansion; P2-P4 with dorso-ventrally flattened (not filiform) carpi, propodi, and dactyli; anterior margins of the P3 and P4 propodi each with a wide and convex extension; posterior margins of the dactyli entire; posterior margins of the P5 propodus spinous; abdomen of males elongated, all somites freely articulating; G1 long and slender, basal portion sinuous; abdomen of adult females with all somites freely articulating. Diagnostic characters of N. simulus n. sp. are the presence of a short, non-bilobed rostrum (bilobed in N. contractus and N. jukesii; see Castro 2000: figs 39, 40), a smooth suborbital border (two triangular, dentiform lobes in N. contractus and N. jukesii; see Castro 2000: fig. 40a, b), abdomen of mature males with smooth somites (transverse ridges in N. contractus and N. jukesii), and the simple, uniramous distal end of the G1 (biramous in N. contractus and N. jukesii; see Castro 2000: fig. 41). The inner surface of the cheliped propodus of the male has dense clusters of plumose setae (barely visible in Figure 1A) as in N. jukesii (see Holthuis 1977: fig. 2c, as Palicus carinipes (Paul’son, 1875)) but unlike N. contractus, which lacks setae. Neopalicus contractus is known from locations across the Indian Ocean (type locality: Maldive Islands), western Pacific Ocean from the Philippines to New Caledonia, and the Marshall Islands in the central Pacific (Castro 2000: table 6, fig. 49). Neopalicus jukesii (type locality: Queensland, Australia) shows a geographical distribution similar to that of N. contractus except that it is also known from the Red Sea and Japan but not from the central Pacific (Castro 2000: table 6, fig. 49). Both species inhabit, sometimes sympatrically, coarse sand in relatively shallow water (44-80 m in N. contractus, 10-146 m in N. jukesii; Castro 2000: table 5) adjacent to coral reefs. In contrast, N. simulus n. sp. is known from rocky bottoms containing coral rubble at depths of 90-200 m (one male [MNHN-B29137], however, was obtained from material dredged at 360-840 m) from the Austral Is, French Polynesia, southeastern Pacific. It is the only known species of Neopalicus in the southeastern Pacific. Neopalicus simulus n. sp. is only known from small individuals, the maximum size recorded among the eight known specimens was only 5.5 mm (cw), an ovigerous female. All three large females showed the large, wide abdomen characteristic of adult female palicoids, two of the three were ovigerous. This is in sharp contrast to N. contractus and N. jukesii, where the largest females ever recorded were 18.6 mm and 15.1 mm (cw) respectively (Castro 2000) and where females of comparable size are pre-adults, and hence with a narrow, thin abdomen.Published as part of Castro, Peter, 2010, A new species and new records of palicoid crabs (Crustacea, Decapoda, Brachyura, Palicoidea, Palicidae, Crossotonotidae) from the Indo-West Pacific region, pp. 73-86 in Zoosystema 32 (1) on pages 75-78, DOI: 10.5252/z2010n1a3, http://zenodo.org/record/452086
