Belarusian State University, Minsk, Belarus
Received February 9, 2004
Abstract—The following new species are described from Southwestern China on the basis of examination of the
material from the Zoological Institute, Russian Academy of Sciences (St. Petersburg), where the types are deposited: Chrysolina warchalowskii sp. n., Ch. wangi sp. n., Ch. mauroi sp. n., Ch. khalyktavica sp. n., Oreomela sichuanica sp. n., and Pyrrhalta silfverbergi sp. n.
In the present communication, new species of the
leaf-beetle subfamilies Chrysomelinae and Galerucinae are described on the basis of examination of the
material collected by I.A. Belousov and I.I. Kabak in
the Chinese provinces Sichuan, Gansu, and Yunnan.
apical angles. Punctation on elytra fine, slightly
coarser than those on pronotum, forming paired rows
with sparse and smaller punctures on intervals.
Epipleura wide at base, gradually narrowed toward
apex, well-visible in lateral view.
The type specimens of the new species described
are deposited in the Zoological Institute, Russian
Academy of Sciences (St. Petersburg).
First segment of fore and middle tarsi dilated,
slightly narrower than 3rd one. Body length 5.7 mm,
width of elytra in middle part 3.5 mm.
Chrysolina warchalowskii Lopatin, sp. n.
Description. Male (holotype). Body apterous,
wide-oval, black, without metallic luster; dorsal side
convex, lustrous, finely punctate. Labrum tar-brown;
maxillary palps, antennae, and legs rufous.
Head weakly lustrous, very finely shagreened, with
sparse and fine, but distinct punctures denser and
coarser on clypeus and at eyes. Antennae short; 1st
segment large and thick; length ratio of segments 14 :
8 : 10 : 8 : 8 : 9 : 8 : 9 : 9 : 11: 16; 5 apical segments
thicker than preceding ones, with short whitish hairs.
Pronotum wide, 2.2 times as wide as long (Figs. 1,
2), with well-developed lateral carinae separated from
disc by depression widened at ends. Punctures of
pronotum distinct, fine and sparse on disc (intervals
between them 2–4 times diameter of punctures) and
coarser and denser on inner side of lateral carinae.
Anterior angles of pronotum strongly projecting, narrowly rounded at apices; posterior angles nearly rectangular. Scutellum flat, smooth, strongly lustrous.
Length of elytra 3 times length of pronotum, 1.16
times their maximum width (at end of anterior 1/3);
lateral margins straightly diverging from humeral angles, then gradually roundly converging posteriorly till
Female. Body length 7.2 mm, width 4.3 mm. Elytra
strongly convex, with repeatedly interrupted paired
rows of punctures. Anterior angles of pronotum more
strongly projecting than those in male, punctation of
lateral carinae denser.
Material. China, “S Gansu, SSW of Minxian, NE
of Luoda, NE of Jiabu, ∼34°01'N/104°04'E, 3600–
4000 m, alpine zone, summit, 16.VII.2002, Belousov
et Kabak leg.,” 1 ♂ (holotype) and 2 ♀ (paratypes).
Diagnosis. The new species clearly differs from all
the Chinese congeners in the uniformly black body
and rufous antennae, palps, and legs, and also in the
strongly projecting anterior angles of the pronotum.
Etymology. The new species is named for the wellknown Polish entomologist Prof. A. Warchalowski,
who made a great contribution to the knowledge of the
fauna and systematics of leaf beetles of the Palaearctic
Region.
Chrysolina wangi Lopatin, sp. n.
Description. Male (holotype). Body apterous,
wide; its length 1.75 times maximum width. Upper
side of body lustrous, blackish green with metallic tint.
Head and pronotum darker than elytra. Antennae, except for rufous lower side of 2 basal segments, and
legs black. Underside black, lustrous.

length, fine anterior edging interrupted in middle, posterior margin not edged. Punctation of pronotum rather
fine and irregular; larger, but not coarse punctures
scattered over entire pronotum, but densest in posterior half (some intervals between punctures equal to
diameter of punctures, others twice as wide); considerably smaller, as though dimpled punctures prevailing
in anterior half, but also sparse.
Elytra wide, only 1.2 times as long as wide, 1.8
times as long as pronotum. Punctures on elytra forming in places irregular rows on disc, irregular at sides;
punctures of same size and depth as those at base of
pronotum; intervals between punctures very finely
wrinkled. Lateral edging narrow, visible in dorsal view
only at humeral angles, becoming linear toward apices; basal margin of elytra edged only along short
distance before humeral angles. Epipleura very wide at
base, gradually narrowing toward elytral apices.
Figs. 17, 18. Pyrrhalta silfverbergi sp. n., aedeagus, ventral and
lateral view.
Diagnosis. This species is closely related to
Ch. kuldzhensis Lop. and clearly differs from it in the
shape of the aedeagus (Figs. 9, 10), shallower lateral
groove of the pronotum, and coloration of the elytra
(in Ch. kuldzhensis, elytra are brownish red, slightly
paler at base and at sides, with tar-black margination
of punctures in rows). The intervals of the elytra in the
paratypes are convex at sides to a varying extent but
not strongly. Apparently, this character may vary in
both species.
Oreomela (Oreomelina) sichuanica Lopatin, sp. n.
Description. Male (holotype). Body wide-oval,
strongly convex, black, with strong brass luster; legs
and antennae black; labrum, tibiae at bases, tarsi, and
4 apical antennal segments brown.
Head wide; frons and vertex convex, with minute
punctures visible only at great magnification; labrum
with rather deep emargination of anterior margin and
long cilia at sides. Antennae rather slender, length
ratio of their segments 14 : 10 : 12 : 10 : 10 : 10 : 11 :
10 : 11 : 14 : 17. Penultimate segment of maxillary
palp short and wide; ultimate one long, narrowly oval.
Pronotum (Fig. 11) 1.5 times as wide as long, widest near middle, arcuately convex; sides widely
rounded, nearly straight before posterior angles; posterior angles slightly projecting in the form of short rectangular teeth. Lateral edging very narrow along entire
First and third segments of fore tarsus of equal
width. Aedeagus (Figs. 12, 13) wide, with tooth at
apex. Body length 6.1 mm, width 3.5 mm.
Material. China, S Sichuan, 35 km NNW of Mianning, NW of Lajiajia—28°48'N/102°02'E, 3400 m,
upper forest zone, 4.VIII.2002, Belousov et Kabak
leg., 1 ♂ (holotype).
Diagnosis. The species is similar to O. mirabilis
Lop. in the shape and character of the pronotal punctation and structure of the aedeagal apex, but differs in
the coloration of the upper side of the body and irregular punctation of the wider pronotum (Fig. 14). The
aedeagus in this species also exhibits a set of differences (Figs. 15, 16).
Pyrrhalta silfverbergi Lopatin, sp. n.
Description. Male (holotype). Body obovate, moderately convex, brown; labrum, femora at apices, tibiae, tarsi, and antennae (except for 1st segment) tarblack. Punctation of head, pronotum, and elytra dense
and distinct, with intervals between punctures shorter
than their diameter. Hairs on upper side of body short,
subrecumbent, with slightly ascending apices, not
concealing background.
Frontal carina convex, triangular, narrow in upper
part. Frontal tubercles transverse, convex, punctate as
vertex, weakly separated by narrow shallow depression in posterior part. Eyes strongly convex. Labrum
with transverse row of setiferous pores. Antennae
thick, with apices extending beyond anterior 1/3 of
elytra, 1st and 3rd segments of equal length, 2nd one

slightly before middle, then nearly straightly narrowing forwards and backwards; disc with 2 shallow depressions on lateral declivities, separated by convexity
widely depressed along middle. Entire pronotum covered with fine and rather sparse hairs. Anterior angles
bearing setiferous pore, dentiform projecting beyond
contour of pronotum. Posterior angles obtused, basal
margin emarginate behind them. Scutellum short and
wide, finely wrinkled.
Elytra 3.8 times as long as pronotum, twice as long
as wide across humeri, gradually and uniformly widened from humeral calli to beginning of apical declivity, then arcuately narrowed toward narrowly rounded
sutural angles. Reflexed lateral margin of elytra wide,
visible in dorsal view from humeral callus to apical
declivity, with punctures as dense and deep as those
on rest of elytral surface. Epipleura gradually narrowing posteriorly from base and disappearing at elytral
apices.

inner lobe shorter than outer one. Anal sternite with
shallow and short emargination at apex. Aedeagus
(Figs. 17, 18) with asymmetrical apex forming triangular point. Body length 8 mm; width 3 mm across humeri and 3.8 mm before apical declivity.

and 3 ♀).
Diagnosis. This species is similar to P. ningpoensis
Gressitt et Kimoto in the size and coloration and differs from it in the shape of the aedeagus and length
ratio of the antennal segments.
