Holotype, ad. 9 (♀), USA, Alaska, 15 mls N of Fairbanks, 1949.iv.28, S. Lienk leg.
Latinised from the old Aleut word ‘alyeska’, meaning mainland (referring to the collecting site on the Alaskan mainland).
Kionopauropus alyeskaensis n. sp. seems to be in a group of its own because it has long and slender antennal branches and 4-parted anal plate, characters not found in species described up to now.
Length. ?, specimen two-parted. Head (Fig. 1). Setae of medium length, striate, tergal ones somewhat clavate, lateral ones cylindrical. Relative lengths of setae, 1st row: a1=a2=10; 2nd row: a1=16, a2=17, a3=20; 3rd row: a1=12, a2=13, 4th row: a1=12, a2=15, a3=?, a4=37; lateral group setae: l1=25, l2=20, l3=?. Ratio a1/a1-a1 not possible to measure. Temporal organ in tergal view narrow, short, ≈0.8 of shortest interdistance; pistil and pore not ascertained. Head cuticle glabrous.
Antennae (Fig. 2) not complete, on segment 4 only three setae found, all thin, cylindrical, striate, their relative lengths: p=100, p’=67, r=10. p as long as tergal branch t, the latter cylindrical, 5.2 times as long as greatest diameter and 1.2 times as long as sternal branch s. The latter branch 3.6 times as long as greatest diameter, anterodistal corner more truncate than posterodistal one. Seta q thin, cylindrical, striate, 0.7 of the length of s. Flagella lost. Globulus g longish, with stalk included 2.7 times as long as wide, 0.5 of the length of s, diameter of g 0.9 of greatest diameter of t, ≈11 bracts, capsule subspherical. Antennae glabrous.
Trunk. Collum segment hidden. Setae on tergites only partly available for study, those studied thin, cylindrical, proportionately long.
Bothriotricha (Figs 3, 4). T1, T2 and T4 lost; proximal 2/3 of T3 (Fig. 3) with thickened axes with distinct oblique pubescence, distal 1/3 very thin with short pubescence; T5 (Fig. 4) thin with short pubescence.
Legs (Figs 5, 6). Setae on coxa and trochanter (Fig. 5) of leg 9 furcate, main branch clavate, secondary branch subcylindrical, a little shorter than main branch, both branches with short oblique pubescence. Tarsus of leg 9 (Fig. 6) straight, tapering, 4.7 times as long as greatest diameter; proximal seta outstanding, curved, tapering, pointed, with depressed pubescence, 4 times longer than straight, cylindrical, blunt, striate distal seta. Cuticle of tarsus glabrous.
Pygidium (Fig. 7).
Tergum. Posterior margin rounded. a-group setae thin, tapering, pointed, curved inward; st cylindrical, blunt, distinctly pubescent, curved inward and converging; relative lengths of setae: a1=10, a2=9, a3=13, st=4. Distance a1-a1 0.8 of the length of a1, distance a1-a2 3.3 times as long as distance a2-a3, distance st-st 2.3 times as long as st and inconsiderably longer than distance a1-a1.
Sternum. Posterior margin with shallow indentation below anal plate. Relative lengths of setae (pygidial a1=10): b1=15, b2=5. Both setae cylindrical, blunt, striate.
Anal plate 4-branched by three deep posterior V-shaped incisions, median one deepest and broadest, lateral branches cylindrical, submedian branches triangular, cut squarely distally; each branch with cylindrical appendages projecting backward, those of inner branches about 0.5 of the length of those on lateral branches, appendages curved inward; plate and appendages glabrous.
