DISTRIBUTION. — This characteristic species has a wide distribution in the Indo-West Pacific region extending from the east coast of Africa (Gulf of Aden to Mozambique and Madagascar) to Taiwan, the South China Sea, the Philippines and Indonesia, N Australia, New Caledonia and Vanuatu. The western form has been separated from the typical form as a subspecies arabicus by Holthuis (1960). The type locality of the species is RV Challenger , stn 209, between Bohol and Cebu, Philippines, at 10°14'N, 123°54'E, depth 174 m, bottom blue mud. The two syntypes of Arctus orientalis Bate, 1888, for which Scyllarus batei Holthuis, 1946 is a new name, are preserved in the Natural History Museum, London. HABITAT. — The species is known from depths of 152-531(531-660) m; most records are from 152 to 400 m, with a peak between 152 and 200 m. A soft bottom is evidently preferred, it has been described as: fine mud; green mud (four times); dark green mud; grey mud; globigerina ooze; clayey mud; mud, shells and coral sand; sand and mud (twice); fine sand or fine sand with mud and shells; black sand. DESCRIPTION The carapace is rather flat and not strongly uneven; it is covered by a short pubescence. The rostrum is truncate, and somewhat constricted behind the top. It bears a small, low, and blunt tubercle, but no tooth. The postrostral carina shows a pregastric, a gastric and a cardiac tooth, all of which are rather low. The pregastric tooth lies somewhat closer to the gastric tooth than to the rostrum, it is rather broad and almost as strong as the gastric tooth, sometimes it has a double top. There are a few small tubercles behind and in front of it. The gastric tooth is somewhat stronger than the pregastric, it ends in a single or double top and is followed by a double row of eight to 12 indistinct squamiform tubercles. The cardiac tooth has the apex blunt or bilobed and is followed by a double row of nine to 16 low squamiform tubercles. Immediately before the cardiac tooth, below its top, there is a pair of small, but distinct tubercles, placed side by side in the cervical groove. The anterior and posterior submedian carinae each bear a group of tubercles, which are most conspicuous anteriorly, where the carina sometimes is somewhat elevated. The branchial carina of the carapace is widely interrupted by the cervical groove. In the gap, just before the anterior end of the posterior carina, there is a sometimes small but always distinct tubercle. The anterior branchial carina ends in two low and blunt teeth, which are placed, one behind the other, on the inner margin of the orbit. The rest of the anterior branchial carina is entire. The posterior branchial carina ends anteriorly in a distinct tooth and bears behind that a single row of about 20 indistinct to very indistinct squamiform tubercles. The intermediate row consists of about six or seven blunt tubercles; furthermore there are a few tubercles at either side of the posterior branchial carina. The lateral margin of the carapace shows a narrow cervical incision and a wider postcervical. Apart from those mentioned, the region between the post- rostral and branchial carinae shows no tubercles. There are about five to seven anterolateral teeth, four or five mediolateral and 12 to 16 posterolateral teeth; all these teeth, apart from the first of each group, show as vague serrations. Between the posterior branchial and posterolateral carinae there are a few small tubercles which are placed close to these carinae leaving the intermediate region smooth. In this same region there is a short blunt oblique carina right behind the cervical groove; it shows some blunt squamiform markings. There are one or two postorbital tubercles, which are small and partly hidden by the pubescence. The marginal groove is wide and rather shallow. Before it there are two, behind it one to three transverse rows of rather indistinct tubercles. The posterior margin of the carapace is emarginate in the middle. In the first abdominal somite the transverse groove is widely interrupted in the middle. The median area of the somite is smooth, like the surface before and behind the groove; however, the posterior half may show indistinct traces of longitudinal grooves. In the next four somites the anterior half of the dorsal surface is entirely smooth. The posterior half is higher and bears a distinct, slightly elevated median carina; in the anterior of the four somites these carinae are slightly higher than in the posterior. The carinae of somites II to IV usually show an indistinct longitudinal groove. The carinae are lobulated at their base. The upper surface of each somite bears a wide transverse groove, which is interrupted by the median carina; this groove extends on to the pleuron. In its distal part, above the base of the pleuron the groove shows two anterior side grooves, which extend into the anterior part of the somite. There is, however, no distinct arborescent pattern of grooves as found in Scyllarus arctus and related species. In the pleuron of the second somite the transverse groove curves forward and slightly up. In the following pleura the groove is straight and ends in the distal part of the pleuron, however, a second groove is placed in the anterior half of the pleura of somites III to V. The upper surface of the somites shows indistinct squamiform tubercles, which may give the anterior margin of the transverse groove a lobulated appearance. The posterior margin of the first to third abdominal somites is slightly emarginate in the middle, sometimes, however, this emargination is hardly noticeable. The pleura are rather broad. That of the first somite is bilobed, the anterior lobe being widest. The pleura of somites II to V have the tip bluntly pointed and directed backward, while the margins are indistinctly serrate or practically smooth. The sixth abdominal somite shows some wide grooves and very few but large tubercles. On the end of the hard part of the telson there are two pairs of teeth, the teeth of the outer pair are placed on the margin of the telson and are broad and bluntly angular. The inner pair is narrower and more acute, it is placed in the median part of the telson at a more anterior level than the outer pair. The anterior margin of the antennular somite bears a low and blunt but distinct tooth in the middle of each half. The anterior margin of the distal (sixth) segment of the antenna is convex and bears five or six teeth, while a very small tooth is found on the inner margin. The teeth are rather elongate triangular, tapering regularly toward the narrowly rounded top; hereby the incisions between the teeth are wide. The fifth segment of the antenna shows a distinct blunt tooth on the inner margin; this tooth bears a dorsal carina. The anterior margin of the fourth segment bears three to seven teeth (not including the apical tooth), the inner of which is the largest. The outer margin of this segment bears two or three large teeth (again the apical one not included); behind these large teeth sometimes an extremely small additional tooth may be seen, while at the base of the apical tooth there sometimes are one or two small denticles. The apical tooth is strong and often reaches beyond the outer part of the distal margin of the sixth segment. The upper surface of the fourth segment shows a single strong oblique carina, which ends in the apical tooth; there are no additional carinae or tubercles on the outer half of the segment. The anterior margin of the epistome is slightly sinuous or somewhat V-shaped, with an incision in the middle. The third maxilliped in situ is only partly visible, being mostly hidden behind the first pereiopods. The pereiopods of this species, especially the fourth and fifth, are unusually long and slender, much more so than in most other Scyllarid species. P.1 is only slightly more heavy than P.2. In P.1 and P.2 the dactylus is naked, or has a few short hairs in the extreme : Published as part of Holthuis, Lipke B., 2002, The Indo-Pacific scyllarine lobsters (Crustacea, Decapoda, Scyllaridae), pp. 499-683 in Zoosystema 24 (3) on pages 520-526, DOI: 10.5281/zenodo.4689240 : {"references": ["HOLTHUIS L.

DISTRIBUTION. — This characteristic species has a wide distribution in the Indo-West Pacific region extending from the east coast of Africa (Gulf of Aden to Mozambique and Madagascar) to Taiwan, the South China Sea, the Philippines and Indonesia, N Australia, New Caledonia and Vanuatu. The western form has been separated from the typical form as a subspecies arabicus by Holthuis (1960). The type locality of the species is RV Challenger , stn 209, between Bohol and Cebu, Philippines, at 10°14'N, 123°54'E, depth 174 m, bottom blue mud. The two syntypes of Arctus orientalis Bate, 1888, for which Scyllarus batei Holthuis, 1946 is a new name, are preserved in the Natural History Museum, London. HABITAT. — The species is known from depths of 152-531(531-660) m; most records are from 152 to 400 m, with a peak between 152 and 200 m. A soft bottom is evidently preferred, it has been described as: fine mud; green mud (four times); dark green mud; grey mud; globigerina ooze; clayey mud; mud, shells and coral sand; sand and mud (twice); fine sand or fine sand with mud and shells; black sand. DESCRIPTION The carapace is rather flat and not strongly uneven; it is covered by a short pubescence. The rostrum is truncate, and somewhat constricted behind the top. It bears a small, low, and blunt tubercle, but no tooth. The postrostral carina shows a pregastric, a gastric and a cardiac tooth, all of which are rather low. The pregastric tooth lies somewhat closer to the gastric tooth than to the rostrum, it is rather broad and almost as strong as the gastric tooth, sometimes it has a double top. There are a few small tubercles behind and in front of it. The gastric tooth is somewhat stronger than the pregastric, it ends in a single or double top and is followed by a double row of eight to 12 indistinct squamiform tubercles. The cardiac tooth has the apex blunt or bilobed and is followed by a double row of nine to 16 low squamiform tubercles. Immediately before the cardiac tooth, below its top, there is a pair of small, but distinct tubercles, placed side by side in the cervical groove. The anterior and posterior submedian carinae each bear a group of tubercles, which are most conspicuous anteriorly, where the carina sometimes is somewhat elevated. The branchial carina of the carapace is widely interrupted by the cervical groove. In the gap, just before the anterior end of the posterior carina, there is a sometimes small but always distinct tubercle. The anterior branchial carina ends in two low and blunt teeth, which are placed, one behind the other, on the inner margin of the orbit. The rest of the anterior branchial carina is entire. The posterior branchial carina ends anteriorly in a distinct tooth and bears behind that a single row of about 20 indistinct to very indistinct squamiform tubercles. The intermediate row consists of about six or seven blunt tubercles; furthermore there are a few tubercles at either side of the posterior branchial carina. The lateral margin of the carapace shows a narrow cervical incision and a wider postcervical. Apart from those mentioned, the region between the post- rostral and branchial carinae shows no tubercles. There are about five to seven anterolateral teeth, four or five mediolateral and 12 to 16 posterolateral teeth; all these teeth, apart from the first of each group, show as vague serrations. Between the posterior branchial and posterolateral carinae there are a few small tubercles which are placed close to these carinae leaving the intermediate region smooth. In this same region there is a short blunt oblique carina right behind the cervical groove; it shows some blunt squamiform markings. There are one or two postorbital tubercles, which are small and partly hidden by the pubescence. The marginal groove is wide and rather shallow. Before it there are two, behind it one to three transverse rows of rather indistinct tubercles. The posterior margin of the carapace is emarginate in the middle. In the first abdominal somite the transverse groove is widely interrupted in the middle. The median area of the somite is smooth, like the surface before and behind the groove; however, the posterior half may show indistinct traces of longitudinal grooves. In the next four somites the anterior half of the dorsal surface is entirely smooth. The posterior half is higher and bears a distinct, slightly elevated median carina; in the anterior of the four somites these carinae are slightly higher than in the posterior. The carinae of somites II to IV usually show an indistinct longitudinal groove. The carinae are lobulated at their base. The upper surface of each somite bears a wide transverse groove, which is interrupted by the median carina; this groove extends on to the pleuron. In its distal part, above the base of the pleuron the groove shows two anterior side grooves, which extend into the anterior part of the somite. There is, however, no distinct arborescent pattern of grooves as found in Scyllarus arctus and related species. In the pleuron of the second somite the transverse groove curves forward and slightly up. In the following pleura the groove is straight and ends in the distal part of the pleuron, however, a second groove is placed in the anterior half of the pleura of somites III to V. The upper surface of the somites shows indistinct squamiform tubercles, which may give the anterior margin of the transverse groove a lobulated appearance. The posterior margin of the first to third abdominal somites is slightly emarginate in the middle, sometimes, however, this emargination is hardly noticeable. The pleura are rather broad. That of the first somite is bilobed, the anterior lobe being widest. The pleura of somites II to V have the tip bluntly pointed and directed backward, while the margins are indistinctly serrate or practically smooth. The sixth abdominal somite shows some wide grooves and very few but large tubercles. On the end of the hard part of the telson there are two pairs of teeth, the teeth of the outer pair are placed on the margin of the telson and are broad and bluntly angular. The inner pair is narrower and more acute, it is placed in the median part of the telson at a more anterior level than the outer pair. The anterior margin of the antennular somite bears a low and blunt but distinct tooth in the middle of each half. The anterior margin of the distal (sixth) segment of the antenna is convex and bears five or six teeth, while a very small tooth is found on the inner margin. The teeth are rather elongate triangular, tapering regularly toward the narrowly rounded top; hereby the incisions between the teeth are wide. The fifth segment of the antenna shows a distinct blunt tooth on the inner margin; this tooth bears a dorsal carina. The anterior margin of the fourth segment bears three to seven teeth (not including the apical tooth), the inner of which is the largest. The outer margin of this segment bears two or three large teeth (again the apical one not included); behind these large teeth sometimes an extremely small additional tooth may be seen, while at the base of the apical tooth there sometimes are one or two small denticles. The apical tooth is strong and often reaches beyond the outer part of the distal margin of the sixth segment. The upper surface of the fourth segment shows a single strong oblique carina, which ends in the apical tooth; there are no additional carinae or tubercles on the outer half of the segment. The anterior margin of the epistome is slightly sinuous or somewhat V-shaped, with an incision in the middle. The third maxilliped in situ is only partly visible, being mostly hidden behind the first pereiopods. The pereiopods of this species, especially the fourth and fifth, are unusually long and slender, much more so than in most other Scyllarid species. P.1 is only slightly more heavy than P.2. In P.1 and P.2 the dactylus is naked, or has a few short hairs in the extreme : Published as part of Holthuis, Lipke B., 2002, The Indo-Pacific scyllarine lobsters (Crustacea, Decapoda, Scyllaridae), pp. 499-683 in Zoosystema 24 (3) on pages 520-526, DOI: 10.5281/zenodo.4689240 : {"references": ["HOLTHUIS L.
