Type locality.

Iran, Alborz Mountains, Damavand, 2000 m.

Notes on type locality.

The locality is situated in the Province of Tehran, in the Damavand County (Central Alborz Range). Data on the label are insufficient to locate whether the holotype has been collected in the surrounding area of the Damavand City or in foothills of the Mount Damavand.

Type material.

Holotype ♂, 'IRAN, Demavand / 2000 m, Elbursgeb. / 2.VI.1960 / leg. J. Klapperich’ (HNHM).

TME: 1 specimen. TGE: 0.

Etymology.

The species is named in honor of the German entomologist and collector of insects Johann Friedrich Klapperich (1913-1987), famous by its very successful expeditions to Southern China, the near and Middle East, and who collected the holotype of this new species.

Diagnosis.

It differs from other representatives of the " Platyderus davatchii " group by very small size of body (BL <7 mm) and pronotum less wide in relation to head (PW/HW= 1.27). In addition, it differs from P. taghizadehi by anterior side of mesofemur ventrally with four setiferous punctures (vs. three setiferous punctures in P. taghizadehi ).

Description.

Habitus. Specimen of small size for Platyderus species, with elongate and convex body (Fig. 2C ). Measurements and ratios. See Table 2 . Color and lustre. Body uniformly dark brown (castaneous), antennae, palpi and legs reddish-brown. Integument moderately shiny. Microsculpture and punctation. Microsculpture of head faint to absent on clypeus and frons, present on vertex. Pronotum with isodiametric sculpticells only posterolaterally, remaining surface without distinct microsculpture. Lateral parts of pro- and metasternum, pro-, mes-, and metepisternum, abdomen and legs with slightly stretched isodiametric sculpticells; ventral part of head, prosternum and metasternum medially without or with reduced sculpticells. Pronotum basal half with several transverse wrinkles. Head. Narrower than pronotum (PW/HW= 1.27). Frontal furrows slightly impressed, shapeless, wrinkled. Paraorbital sulci moderately deep, ending at level close to posterior supraorbital pore. Frons behind frontal furrows wrinkled. Thorax. Pronotum barely wider than long (PW/PL= 1.09), with widest point at second quarter. Anterior transverse impression distinct, posterior transverse one indistinct between adjacent wrinkles. Sides moderately curved apicad and basad, convexly anteriorly, concavely posteriorly; beads of anterior margin and posterior margin present laterally, very faint to reduced in medial 1/8. Metepisternum somewhat longer than wide, MA/MI about 0.8. Elytra. Cylindrical, about one and two thirds as long as wide (EL/EW= 1.70), wider and considerably longer than pronotum (EW/PW= 1.40; EL/PL= 2.60). Stria 7 ending at first umbilicate puncture on left elytron or after reaching first forming a kink connecting with the basal rim on the right elytron. Two or three discal setiferous punctures, anterior puncture near stria 3 on left elytron, and lacking on right elytron, remaining two punctures adjoining stria 2. Umbilicate setiferous series of 15 setiferous punctures on left elytron, with 16 punctures on right elytron. 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. 5E ). Anterior side of metafemur ventrally with two long setae, one in basal third and one in medial third. Male genitalia. Unknown (see “Notes”). Female genitalia. Unknown.

Comparisons.

The species can be easily distinguished from P. lassallei by characters noted in section “Diagnosis” (under P. lassallei ).

Habitat.

Like other representatives of the " Platyderus davatchii " group, P. klapperichi inhabits high-mountain meadows around and above 2000 m a.s.l.

Distribution.

North Iran, Central Alborz Range, most likely in vicinities of Damavand City (Fig. 17 ).

Notes.

The aedeagus with attached parameres and urite IX were lost after the extraction.
