Diagnosis.

See “Diagnosis” under P. felixi sp. nov.

Description.

Habitus. Specimens of small size for Platyderus species (BL: 4.30-6.65 mm; BW: 1.50-2.30 mm), with relatively short, moderately convex body (Fig. 1D ). Measurements and ratio s. See Table 1 . Color and lustre. Integument uniformly yellow-brown to reddish-brown, appendages somewhat lighter than body. Surface moderately shiny. Microsculpture and punctation. Clypeus, vertex and disc of head with reduced microsculpture. Pronotum with regular isodiametric sculpticells posterolaterally and scarcely-visible to absent microsculpture in middle and anteriorly. Ventral surface with microsculpture and dorsal punctation as in P. felixi sp. nov. Head. About two thirds as wide as pronotum (mean PW/HW= 1.37). Eyes moderately convex. Labrum subrectangular, as long as or slightly shorter than clypeus, with anterior margin straight. Frontoclypeal suture and frontal furrows as in P. felixi sp. nov. Paraorbital sulci moderately deep, ending before level of posterior supraorbital pore. Thorax. Pronotum wider than long (mean PW/PL= 1.27), with widest point at second quarter. Anterior and posterior transverse impressions indistinct. Anterior bead lacking in medial 1/10 to 1/8. Sides convex anteriorly, straight posteriorly. Metepisternum somewhat longer than wide, MA/MI= 0.9-1.0. Elytra. Cylindrical, one and a half times or more as long as wide (mean EL/EW= 1.61), wider than pronotum and relatively long in relation to pronotum length (mean EW/PW= 1.31; mean EL/PL= 2.66). Parascutellar striole and striae as in P. felixi sp. nov. Interval 3 with two or three minute discal setiferous punctures, anterior puncture being mostly absent. Umbilicate setiferous series consisting mostly of 15 or 16 punctures. Legs. Posterior side of profemur with one seta in basal third and one in medial third. Anterior side of mesofemur ventrally with four setiferous punctures (Fig. 5C ). Anterior side of metafemur ventrally with two long setae, one in basal third and one in medial third. Male genitalia. Median lobe of aedeagus in lateral view as in P. felixi sp. nov., but significantly narrower, with shaft less protruding dorsally and more constricted proximally (Fig. 8D ); median lobe in ventral view straight, ca. 3.7 times longer than wide; apical lamella nearly symmetrical (Fig. 10D ). Internal sac in lateral view as in P. felixi sp. nov., but with ventral sclerite truncate distally; same in ventral view as in P. felixi sp. nov. Right paramere as that of P. felixi sp. nov. but somewhat finer (Fig. 12D ). Female genitalia (Fig. 13C ). Apical gonocoxite with blunt apex and two dorsolateral ensiform setae. Spermathecal canal connected in medial third of receptaculum.

Habitat.

The holotype and one female paratype were collected along an artificial lake situated in a valley northwest of village Aliabad. They were caught at grassland with lots of stones situated along this lake. The vegetation there consisted of grassland, fields and small orchards - as a whole a cultivated landscape. Other ground beetles collected at this place, together with the new species, were Carabus maurus osculatii Villa, 1844, Poecilus festivus (Chaudoir, 1868) and Amblystomus niger (Heer, 1841).

Cheri Pass environments were represented by overgrazed grasslands with rocks and stones at lower altitudes and stone slopes with sparse vegetation and snow fields at higher altitudes. Similarly, Kamran Pass habitats were consisted of overgrazed grasslands at lower altitude and of stony (sub)alpine slopes with sparse vegetation and snow fields at higher altitudes.

Habitats around Asad Abad represent grasslands on subalpine slopes; specimens there were collected under stones, sometimes near edges of snowfields.

Distribution.

Southwest Iran: Central Zagros Mountain Chains. So far, four isolated populations are known: (1) Borujen County; (2) Kuhrang County (type locality); (3) Shahr-e Kord County (locality southwest Asad Abad); (4) Fereydunshahr County (Kamran Pass), the first three in Chahar Mahal va Bakhtiari Province, the fourth one in Isfahan Province (near border area with Chahar Mahal va Bakhtiari Province).

Notes.

The two specimens collected 7 km northeast of Naghan Town represent the nearest population of P. iranicus sp. nov. to the type locality of P. felixi sp. nov., ca. 17 km in a straight line (Fig. 17 ). The specimen from the environments of the Choghaklor Lake was collected together with three specimens of Platyderus (s. str.) umbratus (Men.).

The distance between the population from the type locality (near Cheri Pass) and that one southwest of Asad Abad is ca. 45 km in a straight line. On the other hand, the distance between Cheri Pass and locality northeast of Naghan Town is ca. 62 km in a straight line. Respectively, the distance between the locality southwest of Asad Abad and that one northeast of Naghan Town is about 47 km in a straight line. The distance between the type locality (near Cheri Pass) and the locality of Kamran Pass is about 67 km in a straight line (the same distance is between the populations from the Kamran Pass and that of Asad Abad). The distance between the Kamran Pass (Fereydunshahr County) and the locality northeast of Naghan Town is about 112 km in a straight line.

" Platyderus Eremoderus vanensis " subgroup

Notes. By its parascutellar striole and striae 1-8 more coarsely and densely punctate and more deeply impressed, the species from Eastern Turkey differ from those of the " Platyderus Eremoderus iranicus " subgroup.
