This publication contains the description of Leistus nanshanicus sp. n. collected by the authors in the Qilian
Shan Mountain Range (China, Gansu). The holotype and some paratypes of the new species are deposited in the
collection of the Zoological Institute of Russian Academy of Sciences (St.-Petersburg, ZISP), other paratypes – in
the collection of Moscow Pedagogical University (MPU, Moscow) and in the collections of the authors (cIK, cIB,
St-Petersburg), J. Farkač (cJF, Praha), A. Koval (cAK, St.-Petersburg), A. Putchkov (cAP, Kyiv).
The following measurements were taken: body length from the anterior margin of labrum to the elytral apex;
head width across eyes; width of the forehead between internal margins of eyes; pronotal length along its median
line; elytral length from the scutellum to the apex of elytra; width of both pronotum and elytra at their broadest
point; pronotal base at the hind angles; elytral base at the humeral angles.
The number of genitalia studied is given in parenthesis after the number of available specimens.
Leistus (Evanoleistus) nanshanicus Belousov & Kabak, sp. n. (figs 1–3)
Ma t e r i a l . 22 specimens measured. Holotype: { (ZISP), China, Gansu, Qilian Shan Mt. Range, S of Zhan-
gye town, 20 km SSW of Huazhaizi village, right source of river (Tayogou), 2900—3400 m, 25.07.1999 (Belousov,
Kabak leg.). Paratypes: 25 (13) {, 18 } (ZISP, MPU, cAK, cAP, cIK, cIB, cJF), collected together with holo-
type. – 3 (1) {, 3 }, same locality, 3400—3450 m, 24.07.1999 (Belousov, Kabak leg.). – 3 (1) {, 5 }, China,
Gansu, Qilian Shan Mt. Range, S of Zhangye town, Tayogou River, SSW of Huazhaizi village, h~3400 m,
24.07.1999 (Belousov, Kabak leg.).
Descr ip t ion . Medium-sized species, habitus narrow and elongate, strongly constricted
at pronotal base (fig. 1), body length 7.58—8.70 mm (males smaller, on the average,
7.96 mm vs. 8.36 mm in females). Apterous. Appendages long and slender. Reddish-brown,
head slightly darkened except for clypeus and sometimes frontal spots. Lateral margins and
median line of pronotum, scutellum, elytral base, suture and margins of elytra lightened. Ap-
pendages, mandibles and labrum yellowish-brown, only femora and middle portions of an-
tennomeres 1—4 barely obscured. Sometimes, colour of upper-side dark brown.
Head (fig. 2) large, only 1.04—1.10 (1.07) times narrower than pronotum and 1.36—1.42
(1.39) times as wide as forehead between eyes, strongly constricted at neck, which is 1.47—
1.63 times (in males, on the average, 1.58 vs. 1.53 in females) narrower than width of head
across eyes. Disk of head convex, smooth medially and rugulouse peripherally. Neck and
frontal furrows rugulouse and sometimes sparsely and superficially punctured. Medial im-
pression on forehead, normally made up of 4 parts. A fine carinula behind supraorbital seta.
I. A. Belousov, I. I. Kabak 106
Eyes protruding, 0.98—1.12 (1.06)
times longer than antennomere 3.
Frontal foveae rather superficial.
Exterior margins of mandibles
strongly explanate at base. La-
brum with 4 well-developed setae,
sometimes two supplementary
small median setae present. 7—8
setae on arcuate gular carina.
Mentum with 4—5 setae, submen-
tum with two setae on each side.
Antennae long, 1.12—1.26 times
(on the average, 1.21 in males
and 1.15 in females) longer than
elytral length. 5-th antennomere
1.33—1.53 (1.46) times longer
than 3-rd antennomere.
Pronotum (fig. 2) small-
sized, cordiform, broadest before
midlength, 1.17—1.28 (1.21) times
as wide as long, its maximal width
1.67—1.78 (1.73) times wider than
the width of base. Lateral margins
gradually rounded anteriorly, well
sinuate before hind angles. The
latter rectangular or slightly
acutangular, pointed at apices,
projecting backward. Anterior
margin 1.10—1.20 (1.16) times as
wide as base of pronotum, angu-
larly or evenly protruding in the
middle, its border distinct
throughout or interrupted medi-
ally; anterior angles small. Prono-
tal base slightly concave or almost
straight. Marginal bead rather
narrow. Basal foveae small and
deep. Basal transverse impression
deep but not sharply outlined.
Apical transverse impression of
pronotum relatively deep. Both apical and basal surfaces of pronotum punctate and rugu-
louse. Disk subconvex, superficially transversely rugulose. Median line not reaching the ante-
rior margin of pronotum.
Elytra elongate, broadest behind midlength, 1.53—1.66 (1.61) times longer than wide,
1.62—1.77 times (on the average, 1.69 in males and 1.73 in females) as wide as head. Elytra
1.48—1.65 (1.59) times wider and 3.01—3.26 times (on the average, 3.07 in males and 3.16 in
females) longer than pronotum. Shoulders almost completely effaced, humeral denticles ob-
tusangular, distance between them 2.19—2.50 (2.34) times less than elytral width at broadest
point. Basal border oblique, weakly arched. Marginal bead narrowly explanate. Elytral striae
very deep, roughly punctate, striae 3 and 4 connecting to each other far from elytral apex.
Intervals convex.
Microsculpture composed of small isodiametric meshes, more superficial on elytra, and
well-developed on head and pronotum.

A new species of the genus Leistus (Coleoptera, Carabidae) … 107
Prosternum with large and sparse punctures. Abdominal segments 1—2 superficially
punctured on sides, the others smooth, each bearing two setae. Anal segment with two setae
in male and four in female.
Anterior tarsi of male slightly dilated, posterior ones 1.55—1.84 times shorter than elytra
(on the average, 1.62 in males and 1.73 in females).
Aedeagus (fig. 3) arched, its apical portion almost straight, evenly narrowed towards
apex in dorsal view. Lamella provided with two carinae on dorsal surface.
Di f fe rent ia l d iagnos i s . The new species is most similar to L. farkaci Sciaky (Sci-
aky, 1994; Farkač, 1995). Both species have the elongate body with small pronotum, the
narrow marginal bead of the latter, the more or less strongly oblique humeri and the similar
aedeagus. Additionally it is worth noting that these species inhabit the neighbouring territo-
ries. Nevertheless L. nanshanicus is readily distinguished by lighter colour, more elongate
body shape (ratio of elytral length to elytral width 1.53—1.66 vs. 1.48—1.54 in L. farkaci, that
of pronotal width to pronotal length is 1.17—1.28 vs. 1.25—1.30 correspondingly), more
oblique shoulders; more slender appendages; larger head, which is only 1.04—1.10 times nar-
rower than pronotum and 1.62—1.77 times narrower than elytra against 1.19—1.25 and 1.79—
1.88 in its counterpart. Additionally, L. nanshanicus differs by the following qualitative char-
acters: more strongly explanate mandibles and deeply sinuate lateral margins of pronotum
before rectangular hind angles as compared with slightly sinuate lateral margins and obtusan-
gular hind angles in L. farkaci; the striae 3,4 connecting to each other far from the elytral

apex while the stria 3 either connects with stria 2 or disappears near the apex in L. farkaci.
The aedeagus of L. nanshanicus is distinct in straight lamella which is barely thickened just
before apex in lateral view and gradually narrowed towards apex in dorsal view as compared
with lamella of L. farkaci bent downwards in lateral view and parallel-sided and constricted
at base in dorsal view.
Distr ibut ion . The new species is only known from the northern slope of the Qilian
Shan Mountain Range (China: Gansu). For the moment, this locality seems to be the
northernmost finding for the members of the subgenus Evanoleistus Jedlička, 1967.
Habi ta t . The species was found in the wide belt of atitudes from 2900 to 3450
m a. s. l., occurring mainly in wet alpine meadows. Nevertheless few specimens were col-
lected in the coniferous forest.
