Etymology:
The specific name refers to the area of distribution.
Diagnosis:
D. antalyaensis
sp. nov.
resembles
D. cephalleniae
Brignoli, 1976
and
D. nativitatis
Brignoli, 1974
by the strongly sclerotised flat spermathecae, the prominent anterior margins of the anterior arch and the large posterior diverticulum (
Figs 3–4
). However, the anterior arc of
D. antalyaensis
sp. nov.
differ from
D. cephalleniae
and
D. nativitatis
. Namely, in
D. antalyaensis
sp. nov.
the tip of the spermatheca is narrow and slightly concave, while in
D. cephalleniae
and
D. nativitatis
it is broad and straight. Besides these:
D. antalyaensis
sp. nov.
has numerous spines on femora III,
D. cephalleniae
has no spines,
D. nativitatis
has only three spines (
Fig. 1
). There is also a significant variation in body size between the species. Comparing the females of the three species,
D. antalyaensis
sp. nov.
is bigger than both
D. nativitatis
and it is larger than
D. cephalleniae
in terms of body length.

Large sized harpacteine spiders. Carapace reddish dark brown; fovea longitudinal, black and distinct (
Fig. 1
). There is a tonal difference between cephalic and thoracic regions. AE, PLE and PME arranged annulary, all of them close to each other. Sternum and gnatocoxae reddish brown. Labium and chelicerae reddish. Cheliceral groove with four teeth. Promarginal teeth strongly developed at the base of the cheliceral groove, of the same size and arranged in a row. The first of the retromarginal teeth is aligned with the second of the promarginal teeth. The retromarginal teeth are smaller than the promarginal teeth, but they are also the same size and approximately two tooth lengths apart (
Fig. 2
).
Abdomen cream colored, covered with short blackish setae (
Fig. 1
). Legs brown. There are tonal differences at the distal and proximal parts of the leg segments. Leg formula: IV, I, II, III. Leg spination and measurements are given in Tables 1 and 2.

Dasumia antalyaensis

1. Habitus, dorsal view 2. Chelicera, ventral view (red dots, promarginal; white dots, retromarginal teeth) 3. Vulva, dorsal view 4. Ditto, ventral view. Abbreviations:
AA
, anterior margin of the anterior arch;
AC
, anterior arc;
PD
, posterior diverticulum;
S
, spermatheca;
SK
, spermathecal keel;
TB
, transversal bar.
Vulva (
Figs 3–4
):
Tip of spermathecal keel narrow, patelliform, very slightly concave. Spermatheca straight. Anterior margin of the anterior arch strongly concave. Edges are wide, convex, membranous, less sclerotized than the middle and oriented towards the anterior. The transversal bar is wider than the anterior arc. Central part strongly sclerotised, membranous towards the margins, with the tips curved inwards. Posterior diverticulum membranous, circular, almost the same width as the width of the anterior arc.
