Abstract and Figures

A new species, Loureedia phoenixi sp.n., is described and illustrated on the basis of two male specimens from Alborz Province of Iran and its distribution is mapped based on the type locality and photographic records. These records represent the easternmost distribution limit of the genus.

The new species is named after the American actor, producer and animal rights activist Joaquin Phoenix in recognition of his praised portrayal of the title character in the 2019 movie "Joker" and as a reference to the male abdominal pattern of the new species, which resembles the famous facial makeup of this character. DIAGNOSIS. The new species differs from congeners by the prolateral arm of the conductor (Pa) which is pointed and almost the same length as the retrolateral arm of the conductor (Ra). The conductor arms are not as pointed and retrolateral arm is distinctly longer than the prolateral one in other species (cf. Figs 3f and 3g-i). DESCRIPTION. Male (holotype). Habitus as in Figs 1a-f, 2a-d. Total length 8.35. Carapace 5.25 long, 4.0 wide. Eye sizes and interdistances: AME: 0.14, ALE: 0.26, PME: 0.29, PLE: 0.19, AME-AME: 0.2, ALE-AME: 0.11. Carapace, sternum, labium, chelicerae and maxillae dark brown with tones of red. Carapace mostly covered by long black setae and scattered short white setae, with localized patches of short red setae mostly in the pars thoracica or the center of pars cephalica. Legs covered with thin black hairs, with distinct regions of white hairs at the joints of all segments that rarely connect with each other, forming distinct white rings. Abdomen with a compact, longitudinal median red stripe with lateral projections with compact white spots at their tips. The anteriormost pair of white spots either contiguous or very close to each other, sometimes merging with a distinct white spot above the pedicel, forming an anterior white shield.

new species and to compare the conductor morphology
of all species of the genus.
Material and methods
The holotype was photographed at the Zoological Muse-
um of the University of Turku, Finland, using an Olympus
Camedia E-520 camera attached to an Olympus SZX16
stereomicroscope. Digital images were stacked using Zerene
Stacker v 1.04. Length of leg and palp segments were mea-
sured on the dorsal side and are listed as: total length (femur,
patella, tibia, metatarsus, tarsus). All measurements are given
in millimetres. The type specimens will be deposited at the
Muséum d’histoire naturelle, Genève, Switzerland (MHNG).
Abbreviations: Eyes: ALE — anterior lateral eye,
AME — anterior median eye, PLE — posterior lateral eye,
PME — posterior median eye. Legs: Fe — femur, Pt

Taxonomy

TYPE SPECIES. Eresus annulipes Lucas, 1857, Patria
ignota [unknown site]
DIAGNOSIS. Males of Loureedia differ from those be-
longing to other genera by the strongly divergent branched
conductor, with the branches subequal to the conductor’s
stem length (vs. only the tip is branched or not branched).
Females of Loureedia cannot be distinguished from those of
Eresus.
COMPOSITION. Four species: L. annulipes (Lucas,
1857), L. colleni Henriques, Miñano et Pérez-Zarcos, 2018,
L. lucasi (Simon, 1873) and L. phoenixi sp.n.
ABSTRACT: A new species, Loureedia phoenixi
sp.n., is described and illustrated on the basis of two
male specimens from Alborz Province of Iran and its
distribution is mapped based on the type locality and
photographic records. These records represent the east-
ernmost distribution limit of the genus.

Introduction
Loureedia Miller, Griswold, Scharff, Řezáč, Szűts
et Marhabaie, 2012 is a recently described genus with
three named species distributed in the Mediterranean,
from Morocco and Spain to Israel [WSC, 2020], all of
which have been surveyed by Henriques et al. [2018].
The genus is known from Iran based on unpublished
material and photographic records [Szűts et al., 2018;
Henriques et al., 2018]. We recently acquired two male
specimens of Loureedia from northern Iran. Examina-
tion of the male palp and comparison of the abdominal
pattern with those of other known species revealed it to
be an undescribed species. Until recently, only three
other species of Eresidae were known to occur in Iran:
one species of Eresus Walckenaer, 1805 and two spe-
cies of Stegodyphus Simon, 1873 [Zamani et al., 2020].
The goal of this paper is to provide a description of the

ETYMOLOGY. The new species is named after the
American actor, producer and animal rights activist Joaquin
Phoenix in recognition of his praised portrayal of the title
character in the 2019 movie “Joker” and as a reference to the
male abdominal pattern of the new species, which resembles
the famous facial makeup of this character.
DIAGNOSIS. The new species differs from congeners
by the prolateral arm of the conductor (Pa) which is pointed
and almost the same length as the retrolateral arm of the
conductor (Ra). The conductor arms are not as pointed and
retrolateral arm is distinctly longer than the prolateral one in
other species (cf. Figs 3f and 3g–i).
DESCRIPTION. Male (holotype). Habitus as in Figs
1a–f, 2a–d. Total length 8.35. Carapace 5.25 long, 4.0 wide.
Eye sizes and interdistances: AME: 0.14, ALE: 0.26, PME:
0.29, PLE: 0.19, AME–AME: 0.2, ALE–AME: 0.11. Cara-
pace, sternum, labium, chelicerae and maxillae dark brown
with tones of red. Carapace mostly covered by long black
setae and scattered short white setae, with localized patches
of short red setae mostly in the pars thoracica or the center
of pars cephalica. Legs covered with thin black hairs, with
distinct regions of white hairs at the joints of all segments
that rarely connect with each other, forming distinct white
rings. Abdomen with a compact, longitudinal median red
stripe with lateral projections with compact white spots at

uous or very close to each other, sometimes merging with a
distinct white spot above the pedicel, forming an anterior

Рис. 2. Внешний вид голотипа Loureedia phoenixi sp.n.: a — сверху; b — снизу; c — сбоку; d — спереди.
Palp as in Figs 3a–f. Femur as long as tibia+cymbium, 3
times longer than wide. Length of conductor’s arms sub-
equal. Tibia shorter than wide. Cymbium about 2 times
longer than wide. Prolateral margin of conductor almost
straight, forming right angle with the posterior margin. Pro-
lateral and retrolateral arms of conductor subequal in length,
both with sharply pointed tips.
Female. Unknown.
PHENOLOGY. All available records of the new species
are from late October and early November, congruent with
the known phenology of most other Loureedia species [Hen-
riques et al., 2018].
DISTRIBUTION. The new species is the first of the
genus to be found outside of the Mediterranean, and this
extends the distribution over 1500 km to the east. It is
endemic to Iran (Fig. 4), collected from the type locality in
Alborz Province, with photographic records in Tehran, Fars
and Kerman provinces, northern and south-central Iran. Al-
though, specimens from the north and south appear identi-
cal, we cannot rule out that the southern populations (for
which only photographic records are available) could repre-
sent a different species; this shall be further investigated
when specimens from those localities are available.
Acknowledgments. We are grateful toward Amir Beigi
(Karaj, Iran) for providing us with the collected material,
and Hadis Asgari (Kerman, Iran), Amir Hossein Bolhari
(Tehran, Iran), Bayan Golavi (Tehran, Iran), Shahram Hesa-
mi (Shiraz, Iran) and Niloofar Sheikh (Karaj, Iran) for pro-
viding us with photographic records. We thank two anony-
mous reviewers and editor Kirill G. Mikhailov for helpful
comments and suggestions. The English of the earlier draft
was kindly checked by Sarah Crews (California, US).

New taxonomic data are provided on the ladybird spider genus Eresus Walckenaer, 1805 in Turkey and Iran. Eresus adaleari Zamani & Szűts, sp. n. is described as a new species, on the basis of a single male specimen collected in Semnan Province, northeastern Iran, and Eresus lavrosiae Mcheidze, 1997, previously known solely from the original description of the male holotype from Georgia, is re-described on the basis of one newly collected male specimen from Kars Province, eastern Turkey. Both of these species are generally dark-colored, which contrasts with the usual coloration of males of this genus. Finally, a few methods and suggestions that might accelerate and improve taxonomic procedures for studying this group are discussed.
