Abstract

The Pseudichnea complex involves the genera Ambitus, new genus, Ampleris, new genus, Sirpa, new genus, and Pseudichnea Schenkling. Ambitus includes one species, A. anticus Opitz, new species. Ampleris includes A. achira Opitz, new species, A. angustata Opitz, new species, A. cava Opitz, new species, A. orosi Opitz, new species, A. primitura Opitz, new species,A. rufocapilla Opitz, new species, and A. buenavista Opitz, new species.Pseudichnea includes P. acia Opitz, new species, P. arima Opitz, new species, P. eliminata Schenkling, and P. gracila Opitz, new species. Sirpa includes S. cauda Opitz, new species, S. flavoapiculis Opitz, new species, and S. skelleyi Opitz, new species. Morphological observations, particularly those based on mouthpart structure, suggest that these beetles are predatory. Their leg construction, especially development of the tarsal pads and ungues, suggest that they are lignicolous beetles that inhabit the woody components of arboreal vegetation, a niche in which they presumably pursue bark-beetle prey. Besides descriptions, this treatise includes a key to genera and species, 72 line drawings, eight electron micrographs, 16 habitus illustrations, and two distribution maps.

Résumé

Les nouveaux genres Ambitus, Ampleris, et Sirpa sont décrits. Pseudichnea Schenkling est redécrit. Ambitus ne comprend qu’une seule espèce, A. anticus Opitz, nouvelle espèce, Ampleris comprend A. achira Opitz, nouvelle espèce, A. angustata Opitz, nouvelle espèce, A. cava Opitz, nouvelle espèce, A. orosi Opitz, nouvelle espèce, A. primitura Opitz, nouvelle espèce, A. rufocapilla Opitz, nouvelle espèce, et A. buenavista Opitz, nouvelle espèce. Pseudichnea comprend P. acia Opitz, nouvelle espèce, P. arima Opitz, nouvelle espèce, P. eliminata Schenkling et P. gracila Opitz, nouvelle espèce. Sirpa renferme les espèces suivantes: S. cauda Opitz, nouvelle espèce, S. flavoapiculis Opitz, nouvelle espèce, et S. skelleyi Opitz, nouvelle espèce. L’étude morphologique, particulièrement des pièces buccales, suggère que ces espèces sont prédatrices. La structure de leurs pattes, en particulier le développement des lobes tarsaux et des ongles, suggère que ce sont des espèces lignicoles présentes dans les arbres où elles se nourrissent probablement de scolytes. En plus de ces descriptions, le présent article comprend une clé des genres et des espèces, 72 dessins au trait, 8 photographies réalisées au microscope électronique, 16 dessins d’habitus et deux cartes de répartition.
