Generic revision of the tribe Nanosellini (Coleoptera : Ptiliidae : Ptiliinae)

A redefinition and phylogenetic analysis of the tribe Nanosellini Barber 19 24 is presented, including 12 previously described genera ( Baranowskiella, Cylindrosella, Hydnosella, Isolumpia, Nanosella, Nellosana, Mikado, Paratu posa, Porophila, Suterina, Throscidium, Throscoptilium) and 14 new genera ( Cylindroselloides, Fijisella, Fijiselloides, Garicaphila, Limulosella, Nell osanoides, Nepalumpia, Phililumpia, Scydosella, Scydoselloides, Tasmangaric a, Throscoptiloides, Throscosana, Vitusella). Type species are listed for e ach genus, including 14 new species or combinations: Cylindroides dybasi, F ijisella vituensis, Fijiselloides nandaivatuensis, Garicaphila pilosa, Limu losella waspucensis, Nellosanoides thayerae, Nepalumpia markusi, Phililumpi a werneri, Scydosella musawasensis, Scydoselloides alajuelaensis, Tasmangar ica chisholmi, Throscoptiloides norcoensis, Throscosana pecki, Vitusella fi jiensis. New genus level combinations are presented: Philagarica new synony m of Mikado; Mycophagus new synonym of Nanosella. At the species level, Pti lum fungi LeConte is proposed as a new synonym for Nanosella fungi Motschul sky. Key characters used in the morphological analysis are illustrated. Phy logenetic reconstructions are presented based on parsimony analyses. Possib le evolutionary relationships within Nanosellini are discussed.
