Material examined

PORTUGAL: many ♂♂ and ♀♀, mesovoid shallow substratum ( MSS) near Gruta das Alcobertas, Estremenho Massif ( MZUF); 1 ♀, Gruta do Soprador do Carvalho, Sicó Massif, 30 Aug. 2007 (SR); 4 ♂♂, 4 ♀♀, 2 juvs, same locality, 30 Aug. 2009 (SR); 5 ♂♂, 6 ♀♀, same locality, 20 Nov. 2009 ( ZMUC).

Previous records

São Mamede, Fátima ( Cruz 1991).

Distribution

This species seems to be endemic to central Portugal.

Remarks

Eluma tuberculata was described by Cruz (1991) based on two females from São Mamede, Fátima. The numerous specimens collected during our research allow us to illustrate the species with its most important features, i.e., the tuberculated body and the schisma on pereonite 1 ( Fig. 30A View Fig ), the cephalon ( Fig. 30B View Fig ), the telson and uropods ( Fig. 30C View Fig ), and the antenna ( Fig. 30D View Fig ). This species has a very plastic morphology concerning the dorsal tubercles, which may be more or less developed. The presence of several adult males permits the description of the male characters which were previously unknown: Pereopods 1 ( Fig. 30E View Fig ) to 6 with brushes of setae on sternal margins of merus and carpus. Pereopod 7 ( Fig. 30F View Fig ) ischium narrow, with straight sternal margin and a ridge on distal part of caudal surface. Pleopod 1 ( Fig. 31A View Fig ) exopod with long, rounded median lobe directed outwards, endopod with distal half having parallel sides and small recurved and pointed apical part not protruding outwards. Pleopod 2 ( Fig. 31B View Fig ) exopod triangular and slightly shorter than endopod.

Ecological notes

This troglophilic species was collected with traps in the MSS (mesovoid shallow substratum, or ‘milieu souterrain superficiel’ sensu Juberthie et al. 1980) in the Estremenho Massif as well as in a cave (Gruta Soprador do Carvalho) in Sicó.
