ABSTRACT

Lipkemera nom. nov. is proposed as a replacement name for Meriola Davie, 1993, which is a junior homonym of the spider genus Meriola Banks, 1895 (Araneae: Corinnidae).

RÉSUMÉ

Lipkemera nom. nov. est proposé en remplacement du nom Meriola Davie, 1993 qui est un homonyme plus récent du genre d’araignée Meriola Banks, 1895 (Araneae: Corinnidae).

INTRODUCTION

I was recently contacted by an arachnologist, Ivan L.F. Magalhães, from the Federal University of Minas Gerais, Brazil, who was kind enough to make me aware that I had accidently created a homonym when I described Meriola Davie, 1993, for a deepwater xanthid , and that this name truly belongs to a genus of spider, Meriola Banks, 1895 (Araneae: Corinnidae). I take this opportunity to propose a new name to correct this situation, and in the process, to honour the remarkable carcinologist, Prof. Lipke Holthuis. It is especially appropriate that it appears in a volume of Crustaceana honouring Prof. Holthuis, because this great man, perhaps more than any other before him, made it his life’s work to establish a stable nomenclature as the foundation of all biology. Prof. Holthuis always took great pleasure in uncovering such matters as my humble homonym!

TAXONOMY

Family XANTHIDAE MacLeay, 1838

Subfamily LIOMERINAE Sakai, 1976 Lipkemera nom. nov. Meriola Davie, 1993: 538-539. Type species. — Meriola rufomaculata Davie, 1993, by original designa- tion. Etymology. — The original genus name Meriola was formed by re-arrang- ing the letters of the related crab genus . The new name honours Prof. Lipke Holthuis, and is formed by adding his first name to the last two syllables of Liomera. Gender is feminine. Diagnosis. — Carapace transversely ovoid; c. 1.5-1.6 times broader than long. Regions moderately defined; orbital margin swollen. Anterolateral mar- gins regularly convex; with four teeth behind the exorbital angle; margins bluntly crested. Front about one-quarter carapace width; moderately project- ing; bilobed; lateral angles bluntly prominent. Posterior margin c.0.4 times carapace width. Upper orbital border concave. Basal antennal segment just touching front; flagellum small and entering orbit. Basal antennular segment moderately broad, palp folds almost transversely. Inter-antennular septum nar- row. Third maxilliped merus wider than long, distinctly shorter than ischium. Chelipeds large and robust; ventral border of chela concave at base of fixed fin- ger; fingers spooned; a narrow gape between cutting margins on male. Walk- ing legs relatively long; compressed; slender; all four pairs of similar length, dactyli straight and flattened; terminating in an acute chitinous tip; anterior margin of merus unarmed terminally. Male abdomen of five free segments; third to fifth fused. Male first gonopod long, moderately stout, curved; tip shaped like “swan’s head”. Long setae present on dorsal margin and contin- uing along lower edge of hollowed tip. Sternum relatively broad. (After Davie, 1993.) Remarks. — Davie (1993) fully discussed this genus (under the name Meriola) and compared it with its congenors. Lipkemera presently contains three species: acutidens Sakai, 1969; Meriola corallina Takeda & Marumura, 1997; and Meriola rufomaculata Davie, 1993 (see Ng et al., 2008). However, a fourth species is being described in a separate contribution by J.C.E. Mendoza in this volume. As Davie (1993) originally remarked: ‘The taxonomic position of Meriola is not completely clear. It largely satisfies the
