| description | Smaragdina limbifera was described by
Escalera [1928] as a variety of S. gratiosa (Lucas, 1845) and
in accordance with the International Code of Zoological
Nomenclature [2000] was considered for a long time a
subspecies of S. gratiosa. Later S. limbifera was promoted
to a distinct species by Warchałowski [2000], who reported
the following differences between S. limbifera from Middle
Atlas (Morocco) and widely distributed in the SouthWestern
Mediterranean S. gratiosa: elytra of S. limbifera
green or green with golden reflexions, with yellow apical spot
and lateral margins, epipleura entirely yellow, apical part of
aedeagus longer, with rounded apex and curved sides (fig.
40); in S. gratiosa elytra greenish blue or blue, with yellow
apical spot, lateral borders bluish, epipleura entirely black,
apical part of aedeagus shorter, triangular, with straight
sides (fig. 41). The author of this article has collected about
100 specimens of Smaragdina on the Rif Ridge (Morocco),
which combined the attributes characteristic for both
species. All specimens were collected on the oak-trees
(probably Quercus fruticosa Brot, 1805). Half of them have
the elytra only with yellow apical spot (fig. 12), the other
half have the elytra with yellow lateral stripe connected with
yellow apical spot (fig. 11). The shape of the aedeagus is also
very variable. Aedeagus of most specimens is triangular with
nearly straight sides as in fig. 41, but the other specimens
have aedeagus with more or less rounded apex as in fig. 40.
I think that S. limbifera is neither a separate species nor a
subspecies, and thus a new synonymy: Smaragdina gratiosa
(Lucas, 1845) = Smaragdina limbifera (Escalera, 1928), syn.
n. is proposed here.
A new species, Smaragdina (s. str.) mirabilis sp. n., is
described from Iran. This species is close to S. persica (Pic,
1911) and S. rapillyi (Lopatin, 2002), but differs in a smaller
size (male – 3–3.3 mm, female – 3.7 mm), black pattern on
the elytra including humeral spot (fig. 16–18) and the shape
of the aedeagus (fig. 36, 37).
A key to Mediterranean species of Smaragdina (s. str.)
with two-colored elytra is given.
A new species, Pachybrachis (s. str.) parthicus sp. n. is
described. It is close to P. boreopersicus Lopatin, 1991 and
P. capreus Weise, 1887; these three species differ from each
other as following:
P. boreopersicus: aedeagus with tooth at apex, its
underside convex, but without sharp median ridge in apical
part, in lateral view strongly curved (fig. 43, 46, 49). Frons
broad, about 2.5 times as wide as upper part of eye. In male,
segment 1 of fore tarsus not very broad, 1.5 times as long
as wide. Elytra generally black, with yellow pattern poorly
developed (fig. 61).
P. parthicus: aedeagus elongate-triangular, without
tooth at apex, its underside less convex, but with sharp
median ridge in apical part, in lateral view slightly curved
(fig. 44, 47, 50). Frons narrower, about twice as wide as
upper part of eye. In male, segment 1 of fore tarsus not very
broad, 1.5 times as long as wide. Elytra generally black, with
convex contrasting yellow strips and spots (fig. 64, 65).
P. capreus: aedeagus slightly compressed before apex,
latter with very weak tooth, without sharp median ridge in
apical part, in lateral view rather strongly curved (fig. 45,
48, 51). Frons broad, at least 2.5 times as wide as upper
part of eye. In male segment 1 of fore tarsus broad, only
1.12 times as long as wide. Elytra generally yellow with
brown longitudinal median stripe, often broadened and
covering almost whole surface except for lateral margins,
but in this case the remainder yellow pattern does not look
contrastingly convex (fig. 66).
Pachybrachis capreus is distributed in Transcaspia,
approximately from Karatau Mountains to Lake Zaisan. The
record of P. capreus from Iran [Schöller M., Nasserzadeh
H. 2010] is likely to be wrong and refer to P. boreopersicus,
since it is based on a specimen with the label «NE Iran,
Kuh-e Binalud, 20 km NE Nishabur, 13.-15.VI.1977, 2500
m, loc. no. 366, det. LOPATIN 1984», identical to the label
of the holotype of P. boreopersicus, which is known only
from the type locality. Pachybrachis parthicus sp. n. is the
southernmost of the three species under consideration.
In the key to species of the subgenus Pachybrachis
[Warchałowski, 2008] P. parthicus will run to the auxiliary
group C, between P. laticollis Suffrian, 1860 (thesis 11) and
P. boreopersicus. Pachybrachis laticollis differs from the
described new species in the shape of the aedeagus (fig.
67–69) and details of coloration. |
