FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK LXI 2000 pp. 65-69 A new Lepidocyrtus species (Collembola: Entomobryidae) from Hungary Gy. Traser A new Lepidocyrtus species (Collembola: Entomobryidae) from Hungary - Lepidocyrtus arrabonicus sp. n. is described from Hungary. The new species is very close to Lepidocyrtus weidneri Hüther, 1971, but cephalic seta T on the vertex and seta p on abd. II are absent. On abd. IV, seta £, is a macrochaeta, while e, in L. weidneri is a microchaeta. Key words: Collembola, Lepidocyrtus, new species, Hungary. INTRODUCTION During the investigation of the Collembolan fauna of the Fertő-Hanság National Park in western Hungary (Sopron region), a blue coloured Lepidocyrtus was found. It is a species new to science. All drawings were made after specimens from the type locality. DESCRIPTION Lepidocyrtus arrabonicus sp. n. (Figs 1-14) Diagnosis: Trunk uniformly blue. Mesothorax not projecting. Antennae without scales; ant. IV without apical bulb. Coxae II —III with, trochanter without scales. Labial seta R well developed but distinctly smaller than the two M setae. All setae in the labial triangle ciliated: M X M 2 REL X L 2 . Unguiculus acuminate. Chaetotaxy of abd. II: a-Bq^q^. Dorsal macrochaetae: i?00 1/00/0101+2. Description: Body length of holotype 1.2 mm, of paratypes 1-1.35 mm. Colour blue to dark purple-blue, except furcula and the pale legs (coxae are blue). Head and antennae only a little paler than the trunk (Fig. 1). Mesothorax about 2 times longer than metathorax, not projecting over the head. Abd. I - VI such as 35 pm : 60 pm : 60 pm : 190 pm : 35 pm : 24 pm. Head nearly circular in dorsal view. Antenna: cephalic diagonal about 1.3, segments I-IV such as 35 pm : 60 pm : 37 pm : 80 pm. Ant. IV without apical bulb, but with a pin seta on top. Basis of ant. I dorsally with three minute setulae arranged in a triangle. Seven R setae between the antennae: RJlfifl^; setae S and T are absent (Fig. 2). Eye
