Immature stages and biology of the enigmatic oxyporine rove beetles, with new data on Oxyporus larvae from the Russian Far East (Coleoptera: Staphylinidae) Author Tokareva, Alexandra Author Solodovnikov, Alexey Author Konstantinov, Fedor text Acta Entomologica Musei Nationalis Pragae 2020 2020-03-31 60 1 245 268 journal article 23167 10.37520/aemnp.2020.014 fa3aaa8e-3e9c-4082-89b8-44854e4354b1 1804-6487 3736556 BE18A83D-CDFC-4B02-82E8-A50E66E32C27 Оxyporus ( Oxyporus ) vittatus Gravenhorst, 1802 Published data. LESCHEN & ALLEN (1988) :description of E, L3, P, biology and hosts; HANLEY & GOODRICH (1994) : notes on L3 morphology, fungal hosts; CAMPBELL (1969) : distribution. Larval morphology. Head and body sclerites without pigmentation, long non-articulated spines on mala, prementum with lateral setae 1/2 length of medial setae ( LESCHEN & ALLEN 1988 ). The earlier claimed absence of sublateral setae was rejected by observations in HANLEY & GOODRICH (1994) . Characters to distinguish this species from O. stygicus are as follows: El1 located medial to uppermost ocelli; head seta L4 absent; 4 A and 4 P setae on pronotum; 7 A and 5 P setae on mesonotum; 4 A and 4 P setae on metanotum; no anterior setae on abdominal tergum I. Development. Egg: 6 hours; instar I: 16.5 hours; instar II: 1.17 days; instar III: 5.86 days; prepupae: 3.6 days; pupae: 5.75 days. Total development duration: 17 days. Behavior. Adults have been collected from April to October with the highest abundance during September and October. Preoral digestion of larvae was observed ( LESCHEN & ALLEN 1988 ).
