Abstract Three new species of Superodontella from Ukraine are described and illustrated, S. multisensillata, S. huculica and S. ruta. These new species differ in the number of sensilla on antennal segment IV, in the size of mucro and postantennal organ, in the shape of dental setae and in the chaetotaxy of labium. Key words: Collembola, Superodontella, new species, Ukraine

Introduction Until now, in the Ukrainian fauna were found six Superodontella species: S. delamarei Rusek, 1991, S. empodialis Stach, 1934, S. montemaceli Arbea & Weiner, 1992, S. nana Cassagnau 1953, S. scabra (Stach, 1946) and S. lamellifera Axelson, 1903 (Nosek & Vysotskaya 1973, Klymovs'ka & Rukavets' 1988, Kaprus' 1998, 1999, 2003, Kaprus' et al., 2004, 2006). All specimens of these species were collected in moss and litter of forest ecosystems and Carpathians subalpine. The recent examination of the cited material revealed seven new species and only one mentioned previously (S. lamellifera). In present paper we describe three of the new species. In the descriptions we used the morphological nomenclature as follows: for the dorsal chaetotaxy of head, thorax and abdomen, after Cassagnau (1974); for the perilabial chaetotaxy, after Gama (1988); for the labial chaetotaxy, after Massoud (1967); for the tibiotarsal chaetotaxy, after Deharveng (1983) and Lawrence (1977); for the classification of anal valves, after Hüther (1962).

Taxonomy Superodontella multisensillata sp. nov. (Figs 1–10) Diagnosis. Postantennal organ about 1.3–1.4 times larger than ocellus B, amoeba-like shape, with four lobes, the posterior one very reduced. Antennal segment IV with 13–14 subcylindrical curved sensilla. Head only with seta c3 in c-row. Thoracic terga II and III with setae m1, m4 (or 3/4) and m7=s. Labium (per half) with four papillate setae and three ordinary setae: F macrochaeta, f and G mesochaetae. Perilabial area with 3+3

The new species is closest to Superodontella lolae (Simón, 1978) from Spain, having the same type of labium and body chaetotaxy, small anal spines and lack of empodium. They differ in the number of sensilla on antennal segment IV (13–14 sensilla in the new species, 9 in S. lolae), and in size of the postantennal organ (1.3–1.4 times larger than ocellus B in the new species, and of equal size in S. lolae according to Simón 1978). The microsensilla ms in S. lolae is placed entirely in the lateral position, behind the seta m7=s and in the new species between setae m7=s and p6.

Claw with an inner tooth in basal 1/3 and a single pair of lateral teeth (Fig. 25). Empodium as a very small bristle. Discussion. The new species is closest to Superodontella huculica by the similar type of labium and labrum, the type of chaetotaxy and the rudimental empodium, the presence of the tooth on claw, the number of sensilla on antenna IV. The species differ from each other by the shape of mucro (short in S. huculica, long in S. ruta) and dental setae (equal in S. huculica, differentiated in S. ruta), and the size of postantennal organ (as large as ocellus B in S. ruta, larger than ocellus B in S. huculica). S. ruta sp. nov. is also similar to S. nana Cassagnau, 1954 sensu Jordana et al. (1997) known from France and Spain, but they differ in the labral chaetotaxy (4–2 in the new species and 3–2–2 in S. nana), and in the shape of dental setae (identical in S. nana, differentiated in the new species).
