Description of the larva and pupa of <i>Haploglossa picipennis</i> (Gyllenhal, 1827) and larva of <i>H. nidicola</i> (Fairmaire, 1852) (Coleoptera: Staphylinidae: Aleocharinae) with taxonomic remarks

The poorly known mature larvae (L3) of Haploglossa piczpennis (Gyllenhal, 1827) and H. nidicola (Fairmaire, 1852) and also hitherto unknown pupal cocoon and pupa of H. picipennis are described in detail, with the illustrations of structural features and setal pattern provided. The differences of the mature larvae between these two species and other known Aleocharinae larvae belonging to the tribes Athetini, Homalotini, Hoplandriini, Liparocephalini, Lomechusini and Oxypodini are presented. The diagnostic larval characters for the genus Haploglossa are proposed for the first time. The differences between pupa of H. picipennis and pupa Of Pella laticollis (Markell, 1844) are listed. Data on the distribution and ecological requirements of both H. picipennis and H. nidicola are also provided.
