60. The following characters permit me to include Ch. koktumensis in the
subgenus Taeniosticha: body black with rufous elytra, 4th, 6th, and 8th intervals
of elytral puncture rows partly darkened, pronotum with convex lateral calli,
which are separated from the disc on entire length (lateral impressions resemble
those in Ch. (Taeniosticha) alatavica), elytra bear regular puncture rows, or 5th
and 6th rows partly confused; in female, 1st tarsal segment bears glabrous stripe
at the base beneath; in male, aedeagus (Fig. 18) is strongly curved, broadly
rounded at apex, bearing two small denticles before apex at ventral side, flagellum
is narrow and long. The structure of aedeagus is similar to that of Ch. (T.)
tianshanica and Ch. (T.) kuldzhensis.

61. Chrysomela diluta KRYNICKI was originally described from Ukraine (environs
of Kharkov) (KRYNICKI 1832). WEISE (1916) disregarded this fact and
treated Ch. diluta KRYNICKI as a junior synonym of Ch. aegyptiaca OLIVIER, which
is distributed in the Near East and North Africa. The original description of Ch.
diluta is very brief: “Nigra, elytris obscure testaceis profunde striato-punctatis,
interstitiis partius punctulatis”. Among the species of Chrysolina distributed in
Ukraine, Ch. reitteri saxonica corresponds to this diagnosis and should be considered
as a senior synonym of Ch. diluta KRYNICKI. Moreover, the name diluta
KRYNICKI, 1832 is a junior homonym of diluta GERMAR, 1824. The name diluta
KRYNICKI should not be replaced, because this name is a junior synonym.
62. Ch. taygetana was originally described (BECHYNÉ 1952) on the basis of
the female specimens only and included in the subgenus Taeniosticha. According
to the original description, this species differs from all other members of
Taeniosticha in the structure of female tarsi, which are entirely pubescent,
without a trace of glabrous stripe beneath. However, in other respects, including
aedeagus structure (Fig. 27), this species is close to other members of Taeniosticha.

63. Ch. dohertyi was included in the subgenus Hypericia by DACCORDI
(1980). However, this species has a number of characters, which make it impossible
to consider it as a member of this subgenus: pronotal lateral callus separated
from disk by wide impression covered with large partly coalescent punctures
basally, but not deep narrow furrow as typical of Hypericia; aedeagus conspicuous
(Fig. 21), flat, with narrow long apical projection, flagellum very narrow,
