Abstract
Article 16.4.2 of the International Code for Zoological Nomenclature (ICZN 1999) states that for a new species name published after 1999 to be regarded as available, it must be accompanied in the original publication “where the holotype or syntypes are extant specimens, by a statement of intent that they will be (or are) deposited in a collection and a statement indicating the name and location of that collection”. In the recent paper by Cleva (2008) treating several species of stylodactylid and bathypalaemonellid shrimps from the Philippines, a new species, Stylodactylus gracilis Cleva, 2008, was described. Although it was mentioned in the introduction that the material from this study will be deposited in three museums in the Philippines, Taiwan and France, the precise depository for the holotype of Stylodactylus gracilis Cleva, 2008, was inadvertently omitted (Cleva 2008: 32, figs. 1, 3A). This unfortunate lapsus makes the name Stylodactylus gracilis Cleva, 2008, a nomen nudum.
