Abstract

The structure of the parameres (lateral lobes) of aleocharine aedeagi was examined in detail, with special attention to the basal lineages. Paramere structure was compared in the context of a hypothesis of phylogeny of the basal lineages of the Aleocharinae and the Tachyporine Group of subfamilies. The ancestor of all contemporary aleocharines had parameres with the following characteristics: dorsobasal and ventrobasal lobes of more similar size than in extant higher aleocharines; dorsobasal lobe (condylite) continuous with distal lobe (not articulated); a striated velum (velar sac), extended from near the base of the dorsobasal lobe to near the apex of the distal lobe and derived from the dorsal surface of the distal lobe; distal arm entire, without articulations or independently movable parts; and four apical setae on the distal lobe, probably with the most apical and basal ones directed mediad and the two medial ones directed more-or-less laterad. In addition, each paramere was articulated with a separate condyle of the median lobe of the aedeagus near the middle of the condylite of the paramere, and the apices of the dorsobasal lobes of the two parameres articulated with each other substantially distal to the articulation with the median lobe of the aedeagus. The most parsimonious resolution of paramere evolution suggests that aleocharine parameres were derived from structures similar to those found in Trichophyinae, Phloeocharinae, and Olisthaerinae and that they are not de novo structures. Hypotheses about homologous regions between aleocharine parameres and those of these latter three groups are suggested.

Résumé

La structure des paramères (lobes latéraux) de l’édéage a été examinée en détail chez les Aleocharinae, plus particulièrement chez les lignées les plus anciennes, dans le but d’établir les bases d’une phylogénie hypothétique des lignées anciennes chez les sous-familles Aleocharinae et Tachyporinae. Les paramères de l’ancêtre de tous les aléocharinés actuels avaient les caractéristiques suivantes : lobes dorsobasal et ventrobasal plus semblables par leur taille que ceux des aléocharinés actuels plus évolués, lobe dorsobasal (condylite) non articulé, en continuité avec le lobe distal, vélum strié partant des abords de la base du lobe dorsobasal et atteignant presque l’apex du lobe distal et issu de la surface dorsale du lobe distal, bras distal entier, sans articulations ou appendices indépendants articulés, enfin quatre soies apicales sur le lobe distal, la plus apicale et la plus basale probablement orientées vers le milieu et les deux médianes plus ou moins vers les côtés. En outre, chaque paramère s’articulait sur un condyle séparé du lobe médian de l’édéage, près du milieu du condylite du paramère, et les extrémités des lobes dorsauxbasaux des deux paramères s’articulaient l’un sur l’autre bien au-delà de l’articulation du lobe médian sur l’édéage. L’hypothèse la plus parcimonieuse de l’évolution des paramères indique que les paramères des Aleocharinae dérivent de structures semblables à celles qui prévalent chez les Trichophyinae, les Phloeocharinae et les Olisthaerinae et ne sont pas des structures de novo. Des hypothèses sur l’homologie de certaines régions des paramères chez les aléocharinés et chez les autres groupes sont proposées.
