Misidentifications “ Artema transcaspica ” – Denis 1958: 112 ( Afghanistan ). — Roewer 1955: 752 ( Iran ). — Gharari & Marusik 2009: 4 ( Iran ). See Note below. Etymology Even though the species was named for a man (Marchese Giacomo Doria, 1840–1913 ), the ICZN (1999 : article 31.1) clearly states that the correct patronym has to be doriae, not doriai. The latter is thus an unjustified emendation. Diagnosis Artema doriae is easily distinguished from other congeners (except A. transcaspica and Artema sp. c.) by the arrangement of modified hairs situated frontally on cheliceral processes ( Fig. 98 ), by the triangular bulbal process c, usually curved and pointing towards prolateral ( Fig. 95 ), and by the distinct ventral process d ( Fig. 94 ). Males are possibly distinguishable from A. transcaspica and Artema sp. c by the cheliceral proximal incline usually with small ridge or process above modified hairs in lateral view (arrows in Figs 100–102 ) ( A. transcaspica usually with smooth incline proximally of modified hairs, see arrows in Figs 131–133 ; Artema sp. c with robust ridge or process above modified hairs, see arrows in Figs 190–191 ). Females differ more easily from other congeners (except A. transcaspica and Artema sp. c) by their quadrilateral epigynal shape. Females appear distinguishable from A. transcaspica by their more trapezoidal epigynal plate rather than rectangular to square-shaped, by median sclerite not reaching posterior margin, and by more distinct and inflated pale median area posteriorly (compare Figs 103–114 with Figs 134–145 ); Artema sp. c differs by wider epigynal plate, and by more inflated and prominent pale median area of epigynal plate ( Figs 195–200 ).

Carapace ochre with light brown median band; ocular area light brown, clypeus with subtle brown rim and light brown band below AME enlarged at base of clypeus to triangular shape (as in Fig. 90 ); legs ochre yellow to ochre without dark rings on femora subdistally but with light brown rings on patellae + tibiae proximally, and tibiae subdistally, tips of femora and tibiae not whitish; sternum ochre with narrow brown margins; abdomen beige with indistinct pale stripes from dorsal to posterior of abdomen with several marks dorsally. BODY. Ocular area slightly elevated; carapace with distinct posterior furrow and distinct median pit; clypeus unmodified; sternum wider than long (3.0/2.2); chelicerae, with frontal row of ~20–25 modified (cone-shaped) hairs on each side, situated on elevated process (see Figs 97–99 ); cheliceral proximal incline in lateral view with distinct small process above modified hairs (see Fig. 97 ); with stridulatory ridges laterally (as in Fig. 118 ); abdomen globose and high; gonopore with four epiandrous spigots.

Coxa unmodified, trochanter with short ventral projection, femur with distinct retrolateral process proximally, ventral membranous area proximally bordered on both sides by heavily sclerotized ridges, and small dorsal projection proximally; femur-patella hinges close together dorsally; patella very short; procursus with proximal dorsal process and weakly developed ventral pocket, and distal dorsal notch on prolateral sclerotized margin (as in Fig. 95 ); bulb with membranous embolus rising from base of processes a and b; process a with subdistal hump; process b narrow, elongated, and pointed; process c small, triangular (as in Fig. 95 ); process d is a distinct small ventral projection distally (as in Figs 94, 96 ). LEGS.Without spines;with long curved hairs, especially on tibiae and metatarsi; retrolateral trichobothrium on tibia 1 at 8%; prolateral trichobothrium present on all tibiae; pseudosegmentation not visible. Male (variation) Tibia 1 in 19 other males: 8.0–22.2 (mean 14.5); color pattern on abdomen varies from pale without any marks to beige with lateral stripes and large marks dorsally; leg color varies from light brown to ochre; ocular area usually light brown; carapace pattern varies from sub-marginal brown marks to pale carapace with median band only; clypeus sometimes without dark band; process c varies in length, sometimes curved and pointing towards prolateral; lateral stridulatory ridges usually present and easy to notice ( Fig. 118 ), sometimes invisible; cheliceral proximal incline (in lateral view) usually with ridge or small process above modified hairs, sometimes absent or indistinct ( Figs 97, 100–102 ). Female In general similar to male; tibia 1 in 20 females : 5.3–14.3 (mean 8.3); stridulatory files laterally on chelicerae more distinct than in males; epigynal plate trapezoidal, consisting of two sclerotized lateral areas that are wider posteriorly, gently swollen posteriorly, and depressed medially anteriorly, pale median area inflated posteriorly with dark median sclerite ⅓–⅔ the length of epigynal plate and not fused at posterior epigynal margin with lateral sclerotized plates, epigynal posterior margin usually straight, sometimes with small median indentation (i.e., Figs 111, 113–114 ); anterior epigynal projections oval, not prominent in lateral view. Intraspecific variation of epigynum as shown in Figs 103–114 . Distribution This species is widespread, ranging from Israel and eastern Turkey in the west, to Afghanistan in the east ( Fig. 1 ). The single specimen from Japan is most probably a human introduction. Note We have not seen the material identified by Denis (1958) , Roewer (1955) , and Ghahari & Marusik (2009) as A. transcaspica (from Pirzada, Afghanistan , and various localities in Iran , respectively). We assume that these authors were all dealing with the very similar A. doriae , judging from its known distribution (we examined one male of A. doriae that was collected from Herat , Afghanistan , and the Iranian localities in the papers above also suggest A. doriae rather than A. transcaspica ).
