A STUDY ON THE GENUS CHRYSOLINA

2. JOLIVET (1992) included several American species, namely Ch. auripennis,
Ch. basilaris, Ch. cyanea, Ch. cribraria, and Ch. inornata in the subgenus
Pezocrosita. However, the presence of developed hind wings, shape of aedeagus
apex (Figs 1-3), and other morphological features permit me to place them close
to Asian species of the subgenus Allohypericia.
MATERIAL
Ch. auripennis: New Mexico: one male; Iowa, Bluffton, 9.1916: one female,
SHIMEK leg.; Iowa: one male, H. WICKHAM leg.; Texas: one male.
Ch. cyanea: Arizona, Pinal Mount.: one male; Arizona: one male.
Ch. basilaris: California: one male.
3. I examined the specimens, which correspond to the original description of Ch.
aeruginosa peninsularis and believe this taxon to be a separate species. The main
differences between Ch. peninsularis and Ch. aeruginosa are the following: body is
larger, length is: 8.2 mm (male) and 8.3-9.6 mm (female) in the specimens at my
disposal, and 7.5-9.0 mm according to BECHYNÉ (1952); pronotum is broadest in the
middle or just anteriorly to mid length, with arc-shaped lateral sides; humeral calli are
very weak or absent. This species resembles Ch. aeruginosa in the aedeagus structure,
coloration (above black with bronze reflection, shining in both sexes) and shape
of prothoracic hypomeron (impression along outer margin of hypomeron with strong
outer border separating smooth marginal stripe which is narrow basally and broad
apically). Ch. peninsularis was described from Korea (Seoul).
MATERIAL
Ch. peninsularis: Russia: Primorski Krai: envir. Khanka lake, Kamen’-
Rybolov, 23.7.1908: 1 male, CHERSKII leg. Uncertain localities: Sombau, 18.9.1900:
1 female, P. SHMIDT leg.; Vanliskhotulev, 27.7.1897: 1 female, GROMBCHEV leg.
4. After publication of the revision (BIEÑKOWSKI 1998) of the subgenus
Anopachys, I had a possibility to <strong>study</strong> the specimens of the rare European Alpine
species, namely Ch. eurina. Now, I confirm that this species belongs to the
subgenus Anopachys. The last segment of maxillary palpi in the male of
Ch. eurina is not „strongly broadened” (BIEÑKOWSKI 1998), but only slightly
broader than in other members of the subgenus Anopachys. Recently two specimens
of this species were unexpectedly collected by Dr. N.B. NTKITSKY in
European Russia (Moscow reg.). The male from this locality is absolutely identical
(including aedeagus structure) with the available Austrian specimens.
MATERIAL
Ch. eurina: Austria: envir. Vienna, Kritzendorf, 29.8.1919: 1 male; Austria:
19.8.1919: 1 male. Russia: Moscow reg., Lukhovtsy Distr., envir. Chernaja
Village, pitfall trap, 27.7.-31.8.2000: one male, one female, N.B. NIKITSKY leg.
