Tylenchorhynchus leptus Allen, 1955 View in CoL .
Dimensions of 30 females: L = 0.79 mm (0.64-0.91); a = 28 (25 - 31); b = 5.5 (5.0- 6.2); c = 11.6 (10.4-12.8); V = 54 (51- 58); G^ = 27 (24- 31); G2 = 26 (23- 30); spear = 26 jx (24-28).
These specimens agree well in length with the types from Colorado, but they are smaller and especially stouter than those described from Sweden by van Rossen & Loof (1962); in accordance with this the tail measures only 3.5 (3.2-3.9) anal body widths against 4- 5 in the Swedish specimens. The empty spermatheca is conspicuous here too. In most specimens the ovaries have a small digitiform process at the blind ends. The median bulb lies at 55 % (52-58) of neck length from head end; the phasmids lie at 36 % (24-46) of tail length from the anus.
This species is common and widespread on Spitzbergen. Found in samples 1, 3, 4, 18, 21, 23, 24, 25, 26, 27, 28, 43, 44, 50, 52, 53, 55 and 56. It is widely distributed in Europe: apart from Sweden and Spitzbergen it has been found in Switzerland (Brienz, Furkastrasse, Dischmatal, Airolo), Austria (Lechtal, Gneis) and Italy (Dolomites).
