Differs from all other species of the " Platyderus Eremoderus languidus " group by the following set of characters: (1) meso- and metatarsomeres dorsally convex and smooth (Fig. 6D ); (2) posterior angles of pronotum incompletely rounded, with tips protruding laterally (Fig. 4C ); and (3) ventral margin of apex of median lobe (lateral view) evidently convex thus apex appears bent up (Fig. 9F ). Platyderus jordanensis sp. nov. and P. languidus share a trait that can be a mark for their close relationships, the apical gonocoxite without nematiform setae. Description. Habitus . Specimens of large size for Platyderus species (BL: 8.70-9.90 mm; BW: 3.00-3.45 mm), with rather elongate and moderately convex body (Fig. 4C ). Measurements and ratios . See Table 3 . Color and lustre . Body and appendages uniformly light reddish-brown, palpomeres and legs somewhat lighter than rest of body. Integument slightly to moderately shiny, head and pronotum shinier than elytra. Microsculpture and punctation . Surface of pronotum with evident microreticulation, sculpticells regular isodiametric. Elytra (intervals, scutellum, basal margin and lateral gutter) with distinct isodiametric sculpticells. Ventral surface largely with more or less impressed isodiametric or slight transverse sculpticells. Head impunctate, nearly smooth, with a few, fine and shallow wrinkles in and laterally of frontal furrows. Pronotum surface mostly smooth, only basal area between foveae longitudinally wrinkled and adjacent lateral areas with rare and superficial punctures that do not reach anterior half. Elytral intervals without apparent punctation. Abdominal ventrite 1 finely wrinkled medially, smooth laterally, other ventrites neither wrinkled nor punctate. Head . One-third or more as wide as pronotum wide (PW/HW= 1.35-1.42). Eyes long, moderately convex. Labrum subrectangular, shorter than clypeus, with anterior margin concave medially. Frontoclypeal suture distinct in middle, indistinct at sides. Frontal furrows small, punctiform. Paraorbital sulci straight, backward surpassing posterior margin of eye, hardly reaching level of posterior supraorbital pore. Thorax . Pronotum about a tenth wider than long (PW/PL= 1.08-1.13), with widest point at medial third. Anterior transverse impression absent; posterior transverse impression barely distinct. Sides sinuate, convex medially and anteriorly, slightly concave posteriorly; anterior bead present laterally, lacking or present in medial 1/10; basal bead present laterally, reduced to absent in medial third or medial half. Metepisternum somewhat longer than wide, MA/MI= 0.88-0.91. Elytra . Elongate, about one and a half times or little more as long as elytra width (EL/EW= 1.56-1.60), two-and-a-half-times as long as pronotum (EL/PL= 2.41-2.60), and a bit less than a half as wide as pronotum (EW/PW= 1.39-1.46), with widest point at medial third. Parascutellar striole linear, as impressed as other striae, not joining stria 1; striae 1-8 and striole slightly to indistinctly punctate; base of stria 1 ending in parascutellar pore, striae 2-5 reaching or barely not reaching basal bead, 6 and 7 ending little before basal bead. Interval 3 with three discal setiferous punctures. Umbilicate setiferous series with 16 punctures on each elytron in three specimens examined, including holotype. Legs . Posterior side of profemur with one or two setae in basal third and one in medial third. Mesofemora with 6 (holotype) or 5 (both paratypes) setiferous punctures on anterior side ventrally. Anterior side of metafemur ventrally with two long setae, one in basal third and one in medial third. Male genitalia . Urite IX subtriangular, with proximal margin symmetrical and pointed at apex (Fig. 7K ). Median lobe of aedeagus in lateral view slender, with narrow basal bulb, shaft broad with proximal part slightly constricted, and short, straight apex (Fig. 9F ); median lobe in ventral view straight, 3.7 times longer than wide; apical lamella (dorsal view) rather short, nearly symmetrical, rounded at tip, with sides straight to slightly concave. Internal sac in lateral view (Fig. 9F ) with ventral sclerite slightly broadened and rounded distally; same in ventral view (Fig. 11E ), with dorsal sclerite large, having small left-sided and large right-sided protuberance, and ventral sclerite straight and rather narrow. Right paramere as on Fig. 12L . Female genitalia (Fig. 15E ). Apical gonocoxite with widely rounded apex and one dorsolateral ensiform seta. Spermathecal canal connected in basal third of receptaculum. Comparisons. In additions to characters mentioned in "Diagnosis" , P. jordanensis sp. nov. differs from geographically close P. brunneus ferranei by pronotum less wide (PW/PL: 1.08-1.13, vs. PW/PL: 1.14-1.21), with anterior margin narrower than posterior margin (PA/PB: 0.78-0.87, vs. PA/PB: 0.88-0.92). For differences between P. jordanensis , from one side, and P. languidus , P. irakensis and P. arabicus , from other side, see sections "Comparisons" (under the first two species) and "Diagnosis" (under P. arabicus ). Habitat. In Little Petra P. jordanansis sp. nov. lives in wadis that have a canyon-like profile and some Mediterranean tree species. There it lives together with Laemostenus quadricollisquadricollis L. Redtenbacher, 1843, Trechus crucifer Piochard de la Brulerie , 1876, Calathus cinctus Motschulsky, 1850, Cymindis andreae Menetries , 1832, and Carabus impressus Klug, 1832. In Wadi Rum the single specimen was found in a dry wadi with Retama shrubs and single Ficus trees in the shade of the walls of the head of the canyon-like valley. It occurs together with ground beetles that are mainly typical for desert habitats ( Laemostenus aegyptiacus Schatzmayr, 1936, Singilis filicornis Peyerimhoff, 1907, Cymindis hierichontica Reiche & Saulcy, 1855, Merizomena castanea Klug, 1832, and Amara maindroni Bedel, 1907). A photograph of the habitat of the latter is given by Casale and Assmann (2017 : 22, fig. 35). Figure 16. Distribution of species from subgenus Platyderus Eremoderus in the western Aegean Sea Region and Turkey: Platyderus chatzakiae sp. nov. (red circle), P. weiratheri (blue circles), P. vanensis sp. nov. (brown circles), and P. vrabeci sp. nov. (yellow circle). Distribution. According to the data available, the species is the representative of the group " Platyderus Eremoderus languidus " in the southern part of Jordan, stretching from the vicinity of Little Petra to areas close to the Saudi Arabian border (Fig. 19 ). As Wadi Rum is in the most southern part of Jordan, the species may also occur in Northwest Saudi Arabia.
