Material examined. 1 female (on slide), Ukraine, Ivano-Frankivs’k district, Gorgany ridge, near Bystrycia village, Fagetum forest, leaf litter, 13.I.1998, leg. R. Godun’ko; male (on slide), Ukraine, L’viv district, near Skole town, Skolivs’ki Beskydy ridge, 700 m alt., Fagus forest, moss on a tree, 18.V.1990, leg. I. Kaprus’; 1 female (on slide), Ukraine, near Odesa town, xerothermic meadow, soil, 15.V.2008, leg. A. Susulovsky; 2 females (on slide), Ukraine, Zakarpattya district, near Uzhhorod town, Quercus and Carpinus forest, leaf litter, 15.X.2007, leg. K. Goblyk; male and 2 females (on slides), Ukraine, L’viv district, near Ivano-Frankove village, Roztochchya Reservation, Fagetum forest, under the bark, 6.V.1993, leg. I. Kaprus’; 2 females (on slide), Ukraine, L’viv district, near Zolochiv town, Hologory Hills, Pinus forest, moss, 7.XII.1991, leg. I. Kaprus’. Biology. Pseudachorutes corticicolus lives in the forest habitats and xerothermic meadows. Bisexual corticolous species. Remarks. Pseudachorutes corticicolus belongs to the species group of Pseudachorutes without organites x and papillate seta L on labium, with one clavate tenent hair on tibiotarsi, with unpaired seta d1 on the head, and with 12+12 setae on Th. II (a2 and a5 setae present). Morphological characters of the Ukrainian specimens of this species fit the recent description of this species from Fennoscandia and Denmark which was published by Fjellberg (1998). Pseudachorutes corticicolus is closest to Pseudachorutes columbicus Rusek, 1991 from Canada and Pseudachorutes janstachi sp. nov. It differ from P. c o l u m b i c u s in the absence a0 seta on head and the presence 3+3 setae on Th. I (a0 present, 4+4 setae in P. c o l u m b i c u s), in the presence 9 setae on labrum (10 setae in P. columbicus) and shape of mandible (with four teeth in P. corticicolus and three teeth in P. columbicus). Differences between P. corticicolus and P. janstachi are given above. Specimens of P. corticicolus described by Jordana et al. (1997) from Spain belong to another species, maybe new to science. It differ from Ukrainian and Scandinavian material by the absence of a5 setae on Th. V, m4 setae on Abd. I–III and a2 setae on Abd. V and by the presence of lateral teeth on the claw.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
