Diagnosis.
This new species, whose morphology is absolutely characteristic for the genus
Antennardia
(
Jaschhof & Jaschhof 2009: 196
)
, is distinguished as follows. As regards diagnostic characters of the male, the compact, straight gonostylus is clearly broadened basally (
Fig. 1
, ↓
1
). The aedeagal apodeme is markedly longer than the tegmen (↓
2
), which corresponds with the condition found in
A. saxonica
Jaschhof
(
Jaschhof 2003
: fig. 3C) but differs from both
A. antennata
(Winnertz)
and
A. gallicola
Mamaev
, in which the apodeme and tegmen are equally long (
Jaschhof 1998
: figs 96b and 94c). The neck of the fourth flagellomere of
A. suorkensis
is longer than the node (
Fig. 2
), which is in line with both
A. antennata
and
A. saxonica
, while
A. gallicola
differs in having the neck shorter than the node. As regards females, six of the specimens studied here of
A. suorkensis
have 21 to 27 flagellomeres (
Fig. 3
), which probably represents only a part of the variability of this species; this compares to
22 to 35 in
A. antennata
(n=9),
31 in
A. gallicola
(n=3), and
17 to 20 in
A. saxonica
(n=4). Regarding spermathecae and ovipositor
A. suorkensis
appears to be not appreciably different from other
Antennardia
, although more thorough comparative study might reveal the need to reconsider this observation. For instance, the basicercus of
A. suorkensis
has a posterior line of conspicuously thick, equally long setae (
Fig. 4
, ↓
3
), whose presence is not mentioned in descriptions of other
Antennardia
.
Etymology.
The specific name is derived from the
type
locality, the immediate vicinity of Suorke Nature Reserve in Swedish Lapland.

Remark.
This is not the
Antennardia
spec. referred to in our earlier treatment of this genus in
Sweden
(
Jaschhof & Jaschhof 2009: 196
). The specimen from
Södermanland
mentioned there remains unidentified to species.
