CURRENT TAXONOMIC STATUS. — Pachygrapsus maurus ( Lucas, 1846) View in CoL , accepted recombination (see Heller 1863: 112).

LECTOTYPE (by present designation). — MNHN-IU-2000-3523 (= MNHN-B3523 ), ♂ 17.0 × 19.5 mm, Oran, northwestern coast of Algeria, M. Deshayes, M. Lucas. — Original label: “ Leptograpsus maurus Edw. , Oran, M. Lucas ”.

PRESERVATION. — Dry. Specimen attached onto cardboard by a stub; RP5 missing.

REMARKS

The species described by Lucas (1846: 20) was based on two male specimens, one measuring 17.0 × 19.5 mm, collected by Deshayes at Oran, located on the northwestern coast of Algeria. Lucas (1846) noted: “This species, of which I have only two male individuals, was found during the summer, in Oran harbour, by M. Deshayes” (“ Cette espèce, dont je ne possède que deux individus mâles, a été rencontrée pendant l’été, dans la rade d’Oran, par M. Deshayes ”). Rathbun (1918: 244) indicated that the ‘type’ was in the “ Paris Museum”, but Poupin et al. (2005: 28) noted that “the first author was unable to locate it” in the MNHN. A sample MNHN-IU-2000-3523 (= MNHN-B3523), with only one male specimen labelled “ Oran, M. Lucas”, thus from the type locality and obviously collected and identified by Lucas, fully corresponds to the male specimen described and measured by Lucas (1846). It is hereby designated as lectotype. The second specimen of the type series is missing.
