Carte de distribution de Metridia pseudoasymmetrica par zones géographiques

| | | | | | | Loc: | | | Antarct. (Pacif.), Sub-Antarct. (Drake Passage) | | | | N: | 2 | | | | Lg.: | | | (823) F: 3,8-3,31; M: 3,5-2,87; {F: 3,31-3,80; M: 2,87-3,50} | | | | Rem.: | bathypelagic.
After Markhaseva (2001, p.46) the speciesis similar to M. asymmetrica Brodsky, 1950, but females differ in the shape and location of spermatheae (oval and overlapping in lateral view in M. pseudoasymmetrica ; round and not overlapping in lateral view in M. asymmetrica) ; distinct indentation in the posterior third of the genital somite in lateral view (indentation weakly pronounced in M. asymmetrica) ; and the subdivided hook-like spines at endopod segment 1 of P2, with markedly unequal horns (the horns are slightly unequal in length in M. asymmetrica). Males of these two species are very simolar, but M. pseudoasymmetrica differs in the presence of small setae supplied with setules in laft lateral distal part of P5 basipod and small distal lateral seta at exopod segment 1 of left P5, and absence of short spinules au urosomal somite 2 on the right and presence of short hairs at urosomal somite 4 on the left. | | | Dernière mise à jour : 17/01/2015 | |
