Therefore, the (seemingly) single empodial seta (with a cryptic second seta) may be a potential synapomorphy restricted to a subgroup within Pholeuina (whose limits would be defined with further studies).…”

Cholevinae are well founded as a monophylum, but their internal phylogenetic relationships constitute a matter of longstanding dispute. The morphology has been the main source of information in most available phylogenetic studies on the subfamily. Most of the characters used, however, were limited to easily visible external structures and genitalia. Here we investigate the informative power of an unexplored character system for the higher-level systematics of Cholevinae: the morphology of the pretarsus and distal margin of the terminal tarsomere. We analysed and documented these structures in representatives of the five most species-rich tribes of Cholevinae (encompassing 13 subtribes) using scanning electron microscopy. We identified several diagnostic features and recognize potential synapomorphies at the tribal, subtribal and generic levels. The architecture of the median and empodial sclerites (including the empodial setae), the shape and composition of the medial projection of the distal margin of the terminal tarsomere, and the armature of the claws were considered a promising source of information for delimiting tribes and subtribes. Our data challenge the traditional view of a close proximity of Eucatopini and Ptomaphagini as well as a previously suggested synapomorphy of Leptodirini, and reinforce the monophyly of Ptomaphagini. This contribution is one of the rare comparative studies on the coleopteran pretarsus and one of very few evaluating the systematic usefulness of the distal margin of the terminal tarsomere in insects. 392

“…Among leiodids, there are only some cases where these structures are illustrated (e.g. Leschen, 2000;Moldovan et al, 2007;, and frequently not in detail (as in Wheeler, 1979;Roubik & Wheeler, 1982;Peck, 1998;Peck & Cook, 2011;Perreau & Perkovsky, 2015 [of an amber fossil]). As these and other studies indicate, the variation of MTS offers a chance to explore a remarkable diversity of attachment structures within a single beetle family.…”

Aos amigos de São Paulo, amizades indeléveis, que tão bem me acolheram na terra da garoa. Vocês sempre farão parte de todas as memórias da vida que tive em sampa. Aliás, vocês desde o início foram parte dela. Agradeço especialmente a Alípio, Caqui, Mamilo, Sabrina, Zé & Carol, e aos muitos outros que conheci através destes. Aos meus pais, Valéria e Rivo, pela constante motivação, amparo, e por estarem sempre por perto, mesmo quando em lados opostos do Altântico. Ao meu brother, Sandro, agradeço pela eterna parceria e amizade inabalável. À Priscila, minha fonte de tranquilidade e valores, os quais sempre me inspiraram. Agradeço pela compreensão e incentivo. Sua companhia me trouxe serenidade e me encorajou a seguir em frente.
