Etymology
. The species name is a patronym in honour of our friend and colleague, Mykola M. Kovblyuk (Simferopol,
Ukraine
).
Diagnosis
. The new species is similar to
A. beckeri
,
A. mariae
(Dahl, 1908)
and
A. taeniopus
. Males can be distinguished from these species by a rounded projection on the tegulum (
Figs 2–3
,
13
). In addition, the shape of tegular (=median) apophysis (
Figs 2–6
,
13–14
) and synembolus (
Figs 7–8
) is also distinct. Females of the new species and
A. mariae
clearly differ from
A. beckeri
(
Nadolny & Kovblyuk 2010: figs 23, 27
) and
A. taeniopus
(
Nadolny & Kovblyuk 2010: figs 25, 29
) by the presence of two anterior epigynal pockets (
Figs 9–11
;
Buchar & Thaler, 2004
: figs 5–6). Females of
A. kovblyuki
sp. nov.
and
A. mariae
differ in the shape of the epigynal septum and the spermathecal reservoirs. The epigynal septum of
A. kovblyuki
sp. nov.
is highly variable (
Figs 9–11
), therefore females of the new species and
A. mariae
are difficult to distinguish.
Description
.
Holotype
: total length 9.0; carapace 4.4 long, 3.2 wide. Median light brown band on carapace widening in anterior part, and reaches the border of the carapace at the level of posterior lateral eyes. Dark brown areas on each side of median band. Carapace with broad white marginal bands. Eye area black. Chelicerae dark brown. Cheliceral claw with hillock on proximal part. Sternum light brown, covered with black setae. Legs and pedipalps light brown. Pedipalpal tibia more than twice as long as wide. Median band with grey lanceolate spot; series of spots on the dorsal abdomen; median band bordered with brown band. Sides of abdomen yellow. Ventral abdomen with grey spot. Tibiae spination: I, II – pl 1-1, rl 1-1,
v 2-2
-2(a); III, IV – d 1-1, pl 1-1, rl 1-1,
v 2-2
-2(a).
Paratypes
(TNU-2814/1), measurements (male/female): total length 8.0 / 9.4; carapace 3.8 / 4.2 long, 2.7 / 2.9 wide. Length of pedipalp segments (male/female): femur 1.4 / 1.4, patella 0.8 / 0.8, tibia 0.7 / 0.7, tarsus 1.3 / 1.2.

Male pedipalp: tegulum with rounded projection on ventral side, retrolateral side of tegular apophysis curved ventrally, embolus flat and wide, synembolus claw-like, distal part of embolus and synembolus hiden behind tegular apophysis (
Figs 2–8
,
13–14
); epigyne with two anterior pockets, septum flat, width of septum more than 1.5 times length, spermatheca spherical (
Figs 9–12
).
Variation
. Males (n = 11): carapace 3.6–4.4 long and 2.6–3.2 wide. Tegular apophysis shape variable (
Figs 5–6
). Females (n = 10): carapace 4.1–4.6 long, 2.9–3.2 wide. Epigyne shape variable (
Figs 9–11
). The grey spot on the ventral side of abdomen can be absent.
Phenology.
Males and females have been found from March to November, with peak activity in April. Females with egg sacs were found in May.
Alopecosa kovblyuki
sp. nov.
and
A. taeniopus
occur sympatrically and have a similar phenology (
Fig. 16
).
Habitats
. Most of specimens were collected in grasslands (steppe; meadows with
Artemisia
&
Limonium
; meadows with
Phragmites
&
Carex
;
Salicornia
&
Halocnemum
on the silt). A few specimens were collected in plantations of various deciduous trees.

Distribution
.
Ukraine
(Mykolaiv area, Crimea, Kherson area, Poltava area),
Russia
(Rostov area). Collection records of
A. kovblyuki
sp. nov.
are shown on

.
Remarks.
Alopecosa kovblyuki
sp. nov.
has similarities with other
Alopecosa
species. However, the structure of the pedipalp and epigyne differs from the
type
species of the genus,
A. fabrilis
. The correct placement of
A. kovblyuki
sp. nov.
can only be resolved when
Alopecosa
is revised.
