CONTRIBUTION TO THE KNOWLEDGE OF EUROPEAN BOURLETIELLIDAE (COLLEMBOLA, SYMPHYPLEONA) .3. DESCRIPTION OF SOME SPECIES OF HETEROSMINTHURUS AND DEUTEROSMINTHURUS

According to our standard of the appendicular chaetotaxy, the followin g species are redescribed: Heterosminthurus bilineatus (Bourlet, 1842) , H. claviger (Gisin, 1958), H. insignis (Reuter, 1876), Deuterosminth urus bicinctus (Koch, 1840), D. flavus (Gisin, 1946), D. pallipes (Bou rlet, 1843), and D. sulphureus (Koch, 1840). Two new species are descr ibed: Deuterosminthurus maculatus sp. n. and Deuterosminthurus pleurac anthus sp. n. A discussion is given on the morphology of the claw, whi ch is used to distinguish genera in the family Bourletiellidae. Append icular chaetotaxic characters are relevant for defining genera, but mo re difficulty applicable for species distinctions. On the basis of suc h characters, apomorphies of Heterosminthurus and Deuterosminthurus ar e emphasized. Setae of body and color pattern are also used for specie s diagnoses, and a key to European species of Deuterosminthurus is pro vided.
