Abstract

Neomeoneurites dissitus sp.nov., the second known species of the genus, is described from Neuquén territory, Argentina. The generic diagnosis is revised to accommodate the species. The structure of the male postabdomen of Neomeoneurites is discussed and some errors in previous interpretations of the postabdomen are corrected. Synapomorphic characters of the male postabdomen in Neomeoneurites include extensive fusion of the hypandrium and sternite 8, loss of the phallic guide, well-developed posteroventral hypandrial projections, and surstyli that are completely fused with the epandrium.

Résumé

On trouvera ici la description de Neomeoneurites dissitus sp.nov. du territoire de Neuquén, en Argentine, la seconde espèce du genre jamais rencontrée. La diagnose générique est révisée pour inclure l’espèce. La structure de la partie postérieure de l’abdomen des mâles de Neomeoneurites est examinée et certaines erreurs d’interprétation sont corrigées. Parmi les synapomorphies relatives au postabdomen des mâles chez Neomeoneurites, il faut noter la fusion importante de rhypandrium et du sternite 8, la perte du guide phallique, la présence de projections hypandriales postéroventrales bien développées et la présence de surstyli complètement fusionnés à l’épandrium.
