03AA14410F76FFF806F65756BDE6FC96.taxon	discussion	REMARKS The emended diagnosis of Leptalpheus includes features of all described and several undescribed species known to the senior author. In view of the increasing morphological heterogeneity of Leptalpheus s. l., several species may be subsequently assigned to other genera (D. Felder pers. comm.). In this case, the diagnosis of Leptalpheus s. s. will be restricted to the type species, L. forceps, and several closely related species. As a first step to the general revision of Leptalpheus s. l. and pending generic rearrangements, we define three morphologically distinctive species groups.	en	Anker, Arthur, Vera Caripe, Jonathan A., Lira, Carlos (2006): Description of a new species of commensal alpheid shrimp (Crustacea, Decapoda) from the southern Caribbean Sea.

03AA14410F70FFF904D65789BD8CFB0A.taxon	discussion	REMARKS The L. pacificus group differs from the L. forceps group (Leptalpheus s. s.) mainly by three characters on the major cheliped: the chela, merus and ischium smooth, without granules or tubercles; the presence of well developed adhesive discs; and the pollex armed with two peculiar teeth, a larger proximal tooth and a smaller subdistal tooth (Banner & Banner 1974; Anker 2001).	en	Anker, Arthur, Vera Caripe, Jonathan A., Lira, Carlos (2006): Description of a new species of commensal alpheid shrimp (Crustacea, Decapoda) from the southern Caribbean Sea.

03AA14410F71FFFB055054B4BEE7F90D.taxon	description	DESCRIPTION Body elongate, carapace and abdomen somewhat compressed laterally, glabrous (Fig. 1 C), with very short, scarce setae.

03AA14410F7BFFF306875789B8C1FC95.taxon	description	This species is presently known only from Oahu, Hawaii (type locality: Pearl Harbor) (Banner & Banner 1974), and from Toliara (Tuléar), Madagascar (Banner & Banner 1983). The latter record needs confirmation. The authors stated that the chelipeds of the single female (TL 7 mm) were more slender, with the large cheliped being 6.3 times as long as broad (4.4 times in the types of L. pacificus) and the small chela 5.6 times as long as broad (5.0 in the types), and suggested that “ the small size of the specimen probably account for the different proportions ”. Unfortunately, this specimen (L. cf. pacificus A in Table 1) was not located in the collections of the MNHN, where it was originally deposited (Banner & Banner 1983). LEPTALPHEUS AXIANASSAE AND L.
