Kalanura, Smolis, 2007

Smolis, Adrian, 2007, Kalanura-a new genus of Neanurini (Collembola, Neanuridae, Neanurinae) from Siberia, with description of four new species, Zootaxa 1511 (1), pp. 1-16 : 2

Kalanura gen. nov.

Diagnosis. Collembola, Neanurinae , Neanurini . Blue hypodermic pigment present on the body. 3+3 dark pigmented eyes. Dorsal tubercles present, well developed, with reticulations and tertiary granulation. Ant. IV with 8 subequal S-chaetae. Mouth part reduced; maxilla styliform, mandible slender. Tubercles Dl, L and So on head separate. Tubercles Di and De on head separate. The line of chaetae Di2–De2 crosses the line Di1– De1 on head (the cross– type, Deharveng 1983). S-chaetae present in typical arrangement and number; 2,2/ 1,1,1,1,1 on each half tergite from th. II to abd. V. Tubercles Di on abd. V separate or fused along midline. Tubercles Di on abd. V separate or fused with tubercles (De+Dl) or (De+Dl+L). Cryptopygy present or absent. Tibiotarsal chaetotaxy 19, 19, 18. Claw untoothed.

Type species: Kalanura babenkoi , sp. nov., here designated.

Discussion. The following combination of characters: the presence of 3+3 eyes and the arrangement of chaetae Di and De on head of the cross– type places the new genus close only to two genera Neanura MacGillivray, 1893 and Thaumanura Börner, 1932. Nevertheless, it can be easily distinguished from the mentioned taxa by the separation of tubercles Dl, L, So on the head (in Neanura fused tubercles L and Dl, or fused L and part of Dl; in Thaumanura fused tubercles L and So). Furthermore, they differ in set of many characters: organisation of tubercles Af and Cl on head (in Kalanura and Neanura separate, in Thaumanura fused), length of chaetae A and B on head (in Kalanura and Thaumanura chaeta A shorter than B, in Neanura chaetae A and B same length), number of chaetae on subcoxae2 of th. II–III (in Kalanura and Neanura 2 chaetae, in Thaumanura 3 chaetae) and length of abdominal segments IV and V (in Kalanura and Neanura abd. V slightly shorter than abd. IV, in Thaumanura abd. V elongate, distinctly longer than abd. IV).

Etymology. The name is derived from the Greek word “kallos”–beautiful.
