REVISION SISTEMATICA Y ANALISIS FILOGENETICO DEL GENERO MISANTL1US SHARP, 1885 (COLEOPTERA: STAPHYLINIDAE: STAPHYLININI)

摘要

Based on the examination of 135 specimens, the systematic revision and phylogenetic analysis of Misantlius were undertaken. A key to identify the species is included. The genus and six known species (Misantlius carinulatus Sharp, 1885; M. discedens Sharp, 1885; M gebieni Bernhauer, 1942; M. optatus Sharp, 1885; M. rufipennis Sharp, 1887; and M. torquatus Sharp, 1885) are redescribed, and four new species are described (M. aequalis, M. brevipennis, M. hondurensis and M. ruftventris), M. jalappae Bernhauer, 1910 is proposed as new synonym of M. optatus. Lectotype and paralectotypes are designated for M. optatus and M. rufipennis. Misantlius gebieni is recorded for the first time for Panama. Misantlius species are demographically very rare, without preference to any resource and are predators. They inhabit cloud forests and oak-pine forests from Mexico and Central America. In the phylogenetic analysis, using Platydracus biseriatus (Sharp, 1884) as outgroup, the monophyly of Misantlius is clearly supported by several synapomorphies, phylogenetic relationships between the species resulted resolved, with M. discedens and M. brevipennis as the most plesiomorphic, and with one or more synapomorphies for each node. Bootstrap analysis resulted in good probabilities of support for each node.
