REMARKS

Williams (1982) described L. metanesa as very close to L. manningi Williams, 1982 (= L. elegans ) of the western Atlantic except for being “less robust” and having a dorsal spine ( Williams 1982: 240). It was described from specimens collected in the Hawaiian Islands and French Polynesia along the northeastern and southeastern limits of the Indo-west Pacific region. The specimens examined by Williams consisted of the type material (seven specimens, all from the Hawaiian Islands), 16 additional specimens from the Hawaiian Islands (USNM 74569, 74577- 74579, 134146, 134147, 134158, 172326, 172327), and one from French Polynesia (USNM 74586). Specimens listed from the Caroline (USNM 74569) and Gilbert (= Kiribati) islands (USNM 74579) ( Williams 1982:

243) were actually collected in the Hawaiian

Islands (see Material examined).

The examination of the type material and the other specimens studied by Williams revealed that although most of the type material had a dorsal spine, one of the paratypes (♂ 9.6 × 5.1 mm, USNM 134157) lacked the spine and another paratype (♂ cw 4.8 mm, USNM 172325) had only a dorsal prominence instead of a spine. Most other Hawaiian specimens, however, lacked a dorsal spine or had a dorsal prominence instead of a spine.

Except for some of the specimens from the Hawaiian Islands and the southeastern Pacific, the presence of a dorsal spine is only a characteristic of juveniles and many (but not all) small individuals. A clear dorsal spine was found in 47 specimens from outside the Hawaiian Islands and the southeastern Pacific, of which 24 were males (14 juveniles, 10 with fully developed first pleopods) and 23 females (16 juveniles, one adult non-ovigerous but with fully developed pleopods, six ovigerous). Their sizes varied from 4.0 × 2.2 to 7.8 × 3.8 mm in males and 4.3 × 2.5 to 10.2 × 5.2 mm in females. In addition, all three juvenile specimens from the Hawaiian Islands, all of which were males (4.4 × 2.3 to 4.8 × 2.5 mm), had a clear dorsal spine. The absence of a dorsal spine is a diagnostic but variable character in L. elegans and L. williamsi (see discussion of L. elegans above). Nevertheless, some specimens

(particularly juveniles, as it seems to be the case

in L. elegans ) do show a spine. Williams (1982) described L. metanesa from mostly juvenile and small specimens and therefore gave the presence of a dorsal spine as a diagnostic character for the species.

Some of the other diagnostic features of L. metanesa (the presence of a spine at the tip of each hepatic swelling and a tooth or tubercle on the meri of the third maxillipeds) also showed unusual variations among the Hawaiian specimens. A large male (12.1 × 6.4 mm, USNM 74579) and the male holotype (8.6 × 5.1 mm, USNM 74570) had a dorsal spine and an acute spine on each hepatic swelling. The holotype has a short tubercle on the meri of the third maxillipeds but the meri is smooth in the first specimen (USNM 75479). A large female from the same station (9.6 × 5.5 mm, USNM 74579), however, lacked a dorsal spine but showed no spines on the hepatic swellings or teeth or tubercles on the third maxillipeds. An unusually large female from a different station in the Hawaiian Islands (14.4 × 7.7 mm, USNM 74578) had a very conspicuous and acute dorsal spine and an acute spine on each hepatic swelling. Another large female (13.1 × 6.7 mm, USNM 74569), however, had a small acute dorsal spine but no spine on each hepatic swelling. Two relatively small males (7.4 × 4.1 mm, the second too soft to measure, USNM 134158) also had a dorsal spine. All other Hawaiian specimens, however, conformed to the characters now used to define the species, that is, a subchela at the end of the last pair of pereopods (P5), a slender gastric region, the absence of a dorsal spine (or the presence instead of a dorsal prominence) in most adult specimens, and a tooth or tubercle on the merus of the third maxilliped.

Part of the morphological variation was found to be a function of sexual dimorphism. Females (particularly the largest ones) rather than the largest males tended to show more prominent teeth or tubercles on the third maxillipeds and more acute spines on the hepatic swellings, a condition similar to that observed in E. phalangium (see above).

Two large females from the southeastern Pacific, one from the Tuamotu Archipelago, French Polynesia (11.7 × 5.6 mm, MNHN-B 28152) and a second from the Sala y Gómez submarine ridge (11.8 × 5.8 mm, ZMMU), showed unusually prominent spines throughout the carapace, abdomen ( Fig. 8C View FIG ), and pereopods ( Fig. 14B, C View FIG ). The Tuamotu specimen, even after preservation, showed a colour pattern ( Fig. 14B, C View FIG ) similar to that of live L. metanesa ( Fig. 14A View FIG ). One of the females (ZMMU), erroneously identified as E. phalangium by Zarenkov (1990: 224), showed a small, acute dorsal spine, as in one of the Hawaiian specimens (USNM 74569). Three smaller males from similar southeastern (USNM 74586, MNHN-B 28214) and eastern Pacific submarine ridges (USNM) locations, however, showed the more characteristic features of L. metanesa .

Six specimens from the south China Sea (USNM 134161), Philippine Islands (USNM 172328), and the western Indian Ocean (USNM 172329, 172330) that were identified by Williams (1982: 243) as “ Latreillia sp. near L. manningi ” were found to be identical to L. metanesa . They all lacked a dorsal spine but were of a relatively large size. All other characters given by Williams as separating these specimens from L. manningi (= L. elegans ) (“somewhat longer” neck, less robust and longer but “variable” supraocular spines and ocular peduncles, “slightly shorter” fingers of chelae, and the absence of spines on the proximal edge of the fused fifth abdominal segments of females) were found to be variable characters in L. metanesa .

A few other specimens departed from the more typical form of the species. A female (7.41 × 4.16 mm, MNHN-B 28121), the only specimen of the species collected from the Loyalty Islands, had a dorsal spine but slight spines on the hepatic swellings, a less spiny appearance, and propodus/P5 carpus (0.61) and cl/merus (0.31) ratios lower than the average for the species (0.66, N = 13 and 0.46, N = 12 respectively). An ovigerous female from New Caledonia (7.15 × 4.03 mm, MNHN-B 28125) had a short prominence on the gastric region, unusually thin, spiny pereopods, and a cl/merus ratio (0.33) similar to the preceding specimen. Its propodus/P5 ratio, however, was similar to the average for the species (0.67). Similar characteristics were observed in two males from New Caledonia (both cl 8.19 mm, MNHN-B 28124). Two juvenile females (5.5 × 3.4 and 5.7 × 3.4 mm, MNHN-B 28185) from New Caledonia had unusually thin pereopods and higher cl/merus ratio (0.37 in both) than average for the specimens of L. metanesa that were measured (0.31, N = 83). In all of these specimens, however, all other characters agree with those diagnostic for L. metanesa , as in the case of the more atypical specimens from the Hawaiian Islands and the southeastern Pacific previously mentioned.

All of the diagnostic characters of L. metanesa (subchelate P5, slender gastric region, absence of dorsal spine in adults, and the presence of a tooth or tubercle on the merus of the third maxillipeds) were present among practically all specimens of the species collected throughout its distribution. Latreillia metanesa , however, shows a wide degree of morphological variation. These variations did not show any particular geographical patterns to suggest the existence of different species or even the existence of a cline. The presence of unusual variants among some of the specimens collected along the easternmost range of the species is perhaps a result of geographical isolation but one that does not support the description of new spe- cies. As in the case of the question of the genetic makeup of the Atlantic populations of L. elegans (see above), the analysis of the DNA of different populations of L. metanesa should provide information on the genetic distance of these populations, particularly those from the easternmost limit of its distribution.
