The members of the subgenus Semenowia Weise, 1889 of the genus Chrysolina Motschulsky, 1860 (Coleoptera: Chrysomelidae)
Species of the subgenus Semenowia of the genus Chrysolina differ from each other in a number of diagnostic characters, so it is not a natural group. Only the type species, Ch. (S.) chalcea should be regarded as a member of this subgenus. Subgenus Ch. (Semenowia) is close to the subgenus Ch. (Pe...

| Summary: | Species of the subgenus Semenowia of the
genus Chrysolina differ from each other in a number of
diagnostic characters, so it is not a natural group. Only
the type species, Ch. (S.) chalcea should be regarded as
a member of this subgenus. Subgenus Ch. (Semenowia)
is close to the subgenus Ch. (Pezocrosita Jacobson, 1901)
and differs from the latter in the presence of seven rows of
punctures on elytron. Ch.(S.)freyensis belongs to the species
group Ch. (obovata) of the subgenus Ch. (Pezocrosita).
It has the following characters of this group: shape of
aedeagus (medial lobe is drawn out and curved upwards),
narrow lateral furrow at pronotal base, and puncturation
of elytron (fine punctures forming rows are connected
with fine longitudinal wrincles). Other species occupy
uncertain position within the genus. Ch. nagaja and
Ch. daccordii represent a natural group, which is close
to the subgenus Ch. (Timarcholina) and differs from the
latter in smaller body and absence of the denticles on the
fourth tarsomere. Ch. mirabilis forms a natural group with
Ch. davidiani, Ch. luyoui and Ch. sicieni. The distinctive
features of this group are dorsal colour (shining, green with
purple stripes), broad pronotal lateral impressions, elytra
with irregular rows of very fine, obsolete punctures, and
enlarged protarsomere 1 in male. |
