The larval morphology of 7 species belonging to 3 genera of the tribe Agathidiini is given. Third larval instar of Agathidium discoideum Erichson and Liodopria serricornis (Gyllenhal), the first larval instar of Ag. varians varians Beck and Anisotoma orbicularis (Herbst) are described for the first time, third larval instar of Ag. varians variansand Ag. mandibulare Sturm are redescribed in detail, and third larval instar of two species without exact identification (Ag. pisanum or Ag. badium and Ag. bescidicum or Ag. plagiatum or Ag. confusum) are also included. Based on comparative morphology of all known larvae of Agathidiini, cladistic analysis was made and phylogenetic relationships within this tribe of family Leiodidae was hypothesised. Sixty two characters were polarized using outgroup comparison and ontogenetic criterion. No apomorphies distinguish genera Anisotomafrom Agathidium, thus synonimization of them is suggested. Position of Liodopria serricornis in the tribe Agathidiini is doubtful because of lack of synapomorphic characters.
