REMARKS

In 16 specimens examined a few unusual armaments have been observed. The lateral margin of rostrum can have three to five spines, instead of the usual four. There are two intermediate spines on the carapace, instead of one, in a female cl 42 mm ( MNHN As 626). The distoventral spine of carpus of second pereopod was absent on the smallest specimen examined (male cl 40 mm). Spines were also occasionally missing on inner and outer faces of dactyls of ambulatory legs.

Enoplometopus gracilipes is morphologically related to E. holthuisi Gordon, 1968 and E. voigtmanni Türkay, 1989 . The three species have in common the same disposition of spines on the carapace, a similar shape of pleura of abdominal somites II-V, and a similar long and slender chela, smooth on the upper and lower faces of palm, with fingers as long as the palm. Enoplometopus gracilipes is at once distinguished from the two other species by its coloration, being the only one with spots on the carapace whereas the lateral face of the carapace has a large white circle in E. holthuisi , and a network of streaks in E. voigtmanni . In the absence of coloration E. gracilipes can be distinguished by examination of the posterior margin of the sixth abdominal tergite, which has no spines, while it has two short lateral spines in the two other species (cf. Fig. 5E with Fig. 7E ). Although shape of male first pleopod is still not known in E. voigtmanni , it is also obviously different between E. gracilipes and E. holthuisi (cf. Fig. 5F with Fig. 7F ). Finally, E. gracilipes is a deep-water species, mostly collected at depths greater than 100 m, while E. holthuisi and E. voigtmanni are only known at depths less than 100 m.

Illustrations of an undetermined specimen have been published in two Japanese books ( Anonymous 1973; Miyake 1983). According to its coloration, this unique specimen could reasonably belong to E. gracilipes . However, this provisional determination must be confirmed when more specimens are available from Japan.

SHORT DESCRIPTION

(SPECIMEN FROM FRENCH POLYNESIA)

Rostrum with three spines on lateral margin. Carapace with five median, two postcervical, one intermediate, one supraocular, and three lateral

spines ( Fig. 7A ). Chela 4.6 times as long as wide, palm ovate in cross section ( Fig. 7C ). Upper and lower faces of palm smooth; outer margin with eight spines; inner margin with two rows of five spines, converging distally. Fingers 0.4 times as long as chela, with sharp inward curved crossing tips; cutting edges denticulated with five or six larger teeth; outer edges smooth, furnished with very long setae extending well beyond tip of fingers (see Remarks).

Second pereopod circular in cross section, reaching to proximal third of chela. Merus and carpus with distoventral spine. Propodus subequal to merus, furnished with few long setae; distoventral angle with process armed with five to eight tiny spines on upper margin, and two mobile spines, distally ( Fig. 7D ). Dactyl short, 0.2 times as long as propodus. Pereopod 3 and 4 shorter than P2, with terminal pincers reduced. Pereopod 5 is the shortest and has no terminal pincer.

Pleura of abdominal somites II-V, each with sharp, posteriorly curved tooth; pleuron of somite VI with blunt tooth ( Fig. 7B ). Posterior margin of tergite VI with three median tubercles flanked by two short spines ( Fig. 7E ). Male first pleopod subrectangular with deep incision on distal margin ( Fig. 7F ). Telson with two lateral spines of similar size and two distolateral spines, inner one longer ( Fig. 7E ).

Coloration ( Fig. 6 )

Ground color of body orange with white at tip of spines. Lateral face of carapace with large white circle, on distal half, and wavy white lines on proximal half. Abdominal somites with white spots bordered by dark orange rings, as illustrated on Figure 6 . Chela orange with faint reticulated lines on palm, and alternated dark and light orange bands on fingers. Ambulatory legs banded in white and orange on whole length.

REMARKS

Because of the particular shape of its chela that is distinct from typical E. holthuisi , the specimen trapped around the French Polynesian islands had been previously attributed to a new species ( Poupin 1996a). In this work it has been compar- ed carefully with the holotype of E. holthuisi , which confirms the distinctive shape of its chela (cf. Fig. 7C with Fig. 7G ). It is less elongated, being 4.6 times as long as wide, vs 6.4 in holotype, and has shorter fingers, 0.4 times as long as chela, instead of 0.5 in holotype. Outer edges of the fingers are also furnished with very long setae ( Fig. 6B ), absent on the holotype and never observed on photographs of E. holthuisi consulted during this study. Despite these obvious differences, all other characters of the Polynesian specimen are those of E. holthuisi , particularly the shape of male first pleopod, a very distinctive character in this species. It thus seems that the peculiar shape of its chela must be attributed to its small size.

Enoplometopus holthuisi is related to E. voigtmanni . As denoted in the Remarks of E. gracilipes , the two species are easily separated by their coloration, in particular the lateral face of the carapace which has a large white circle, in E. holthuisi , and a network of streaks, in E. voigtmanni . They also differ by the shape of the spines on the abdominal pleura II-V, as illustrated in Türkay (1989: figs 1, 2b). When male first pleopod is known in E. voigtmanni it will be interesting to check if the two species can also be separated by the shape of this appendage. Enoplometopus holthuisi is also related to E. gracilipes , and the differences between the two species have been listed under E. gracilipes . It is interesting to point out that the single specimen of E. holthuisi caught during the fishing operations of the Frv Marara (stn 423, 80 m) was associated in the trap with E. gracilipes . Enoplometopus holthuisi is usually reported in shallow waters, between 20-50 m, while E. gracilipes is mostly caught at depths greater than 100 m. Therefore, it appears that these two species can co-occur at intermediate depths, between 50- 100 m.

REMARKS

This is the most common species found in the Atlantic and the only Enoplometopus lobster report- ed from the tropical west Atlantic. In the tropical east Atlantic it co-occurs with E. callistus . In central Atlantic Islands, St Helena and Ascencion islands, it must be very common as the collector of the specimens examined herein indicates on the label: “[...] specimens from St Helena are larger and are often eaten there, mostly by fishermen as they get into their fish and lobster traps”.

Chela broad and compressed, 2.6-3.9 times as long as wide, upper and lower faces of palm smooth; outer margin of dactyl with nine or 10 spines disposed over entire length (see Remarks). Dactyl of second pereopod 0.3 times as long as propodus. Pleura of abdominal somites II-V finely denticulated and with sharp median tooth ( Fig. 8B ). Distal margin of male first pleopod with small denticulations, as illustrated on Figure 8C , without deep indentation. Telson with two lateral and two distolateral spines.

COLORATION

Carapace, abdomen and chelae pale orange with large orange red patches. Antennae white. Ambulatory legs orange with narrow white bands ( González Pérez 1995; Wirtz 1996).

REMARKS

The arrangement of spines on the carapace, as indicated herein, differs slightly from the original description by Intès & Le Loeuf (1970). These authors indicate four median plus two postcervical spines, instead of five median plus one postcervical spine in this work. This is because they have considered as “postcervical” the posteriormost median spine that is in fact situated on the cervical groove, as observed also in E. crosnieri .

The arrangement of spines on the outer margin of dactyl of chela was first used by Bouvier (1915) who distinguished two states: 1) two to three spines disposed at tip only; or 2) spines disposed over the full length. Although state 2) clearly applies here for the type of E. callistus , it has been observed that spines on the proximal two thirds are reduced to spiny scales in the two larger specimens examined (MNHN As 627), a variation that could be a source of misidentification if not taken into account (cf. Fig. 8A and Fig. 8D ).

Marginal denticulation of pleura II-V is a new diagnositic character for the genus. It has also been observed in a juvenile of E. holthuisi (Ƌ cl 22.5 MNHN As 271) which has tiny denticles on pleura II-III only, and is also illustrated for a juvenile of E. antillensis in Manning & Camp (1989: 415 , fig. 4D). Therefore, it seems to be a juvenile character that is retained in the adult stage of E. callistus .
