Type locality.

Iran, Chahar Mahal va Bakhtiari Province, 10 km W Naghan Town, 31.9410, 50.6014, 1492-1505 m.

Notes on type locality.

The distance from Naghan Town to the type locality is about 10 km in straight line and the direction is to the west of the town. The GPS coordinates and height indicated are more or less correct as they well correspond to the river that flows towards the village of Do Polan. In fact, the type locality is closer to the last village than to Naghan Town.

Etymology.

Latinized patronym name after Ron Felix (Berkel-Enschot, Netherlands), an enthusiastic coleopterologist working on the taxonomy of carabid beetles, with great collecting skills, who collected part of the type series of the new species.

Diagnosis.

It is distinct from P. iranicus sp. nov. in the pronotum significantly wider than head (PW/HW ≥1.45, vs. PW/HW ≤1.45) and elytra noticeably less wide in relation to length (EL/EW ≤1.55, vs. EL/EW ≥1.55). In addition, median lobe of aedeagus (lateral view) of the new species is larger, with shaft broader and apex barely bent up ( P. iranicus has significantly narrower shaft and apex more distinctly bent up; Fig. 8C, D ).

Description.

Habitus. Specimens of moderate size for Platyderus species (BL: 6.00-7.00 mm; BW: 2.20-2.50 mm), with relatively short, moderately convex body (Fig. 1C ). Measurements and ratios. See Table 1 . Color and lustre. Integument uniformly reddish-brown, appendages somewhat lighter than body. Surface moderately shiny. Microsculpture and punctation. Disc of head with less distinct microsculpture. Pronotum with regular isodiametric sculpticells posterolaterally and slightly stretched isodiametric sculpticells anterolaterally, microsculpture faint to absent in middle. Ventral surface (excl. gula) microsculptured, sculpticells isodiametric (mentum, submentum, pro-, mes-, and metepisternum, prosternum and abdominal ventrites laterally) or slightly stretched isodiametric (genae, medial surface of prosternum, metasternum, abdominal ventrites medially and legs). Head. As wide as a half of pronotum (mean PW/HW= 1.49). Eyes moderately convex. Labrum subrectangular, as long as clypeus, with anterior margin straight. Frontoclypeal suture distinct in middle but very fine, lacking at sides. Frontal furrows shallow, punctiform. Paraorbital sulci moderately deep, ending slightly before or at level of posterior supraorbital pore. Thorax. Pronotum distinctly wider than long (mean PW/PL= 1.31), with widest point at second quarter. Anterior and posterior transverse impressions indistinct. Anterior bead present medially, very fine. Sides convex anteriorly, nearly straight posteriorly. Metepisternum slightly longer than wide, MA/MI= 0.90-0.95. Elytra. Cylindrical, one and a half time as long as wide (mean EL/EW= 1.52), wider and quite longer than pronotum (mean EW/PW= 1.31; mean EL/PL= 2.62). Parascutellar striole and striae moderately impressed, wide; striole short, not joining stria 1; striae 1-6 reaching basal bead, 7 reduced before. Following aberration exists in two specimens, striae 3 and 4 posteriorly, each of them fusing separately with stria 2 and joined stria reaches lateral gutter, otherwise striae posteriorly as in subgeneric description. Interval 3 with three or two minute discal setiferous punctures situated as follows: anterior puncture (in most specimens missing on one or both elytron) adjoining stria 2, in middle of interval 3 or adjoining stria 3, remaining two punctures adjoining stria 2. Umbilicate setiferous series mostly consists of 16 punctures on elytron, rarely with 17 punctures. Legs. Posterior side of profemur with one seta in basal third and one in medial third. Mesofemur with four setiferous punctures on anterior side ventrally (Fig. 5B ). Anterior side of metafemur ventrally with two long setae, one in basal third and one in medial third. Male genitalia. Urite IX small, oval, with proximal margin slightly asymmetrical and rounded (Fig. 7C ). Median lobe of aedeagus curved in lateral view, with short basal bulb, long and broad shaft moderately constricted proximally, and apex hardly reversely turned up; median lobe in ventral view straight, ca. 3.7 times longer than wide; apical lamella more or less asymmetrical. Internal sac in lateral view (Fig. 8C ) with ventral sclerite distinctly broadened and rounded distally; same in ventral view (Fig. 10C ), with dorsal sclerite forming a concave left protuberance and a convex right curve, and ventral sclerite narrow and completely straight. Right paramere rather short and crooked (Fig. 12C ). Female genitalia (Fig. 13B ). Apical gonocoxite with pointed apex and two dorsolateral ensiform setae. Spermathecal canal connected in medial third of receptaculum.

Comparisons.

The new species lives in sympatry with Platyderus (s. str.) umbratus ( Ménétriés, 1832). However, P. felixi has pronotum more coarsely punctate in basolateral parts with punctures almost reaching the lateral margin, mesotibia with four setiferous punctures on its anterior side ventrally, and short urite with apex more symmetrical (Fig. 7C ), whereas P. umbratus possesses pronotum shallowly punctate in base with punctures mostly limited to the basal impressions, mesotibia with two setiferous punctures on its anterior side ventrally, and long urite with apex curved to left (as in Fig. 7O ).

Habitat.

The specimens were hand collected by R. Felix and J. Muilwijk close to the village Do Polan along the river course. The vegetation there consisted of (over)-grazed grassland, fields and small orchards; characteristic of a cultivated landscape.

Distribution.

Southwest Iran: Central Zagros Mountain Chains (Chahar Mahal va Bakhtiari Province, Kiar County; Fig. 17 ).
