Persescaphium pari n. sp.

( Figs 1 to 5)

Type locality. Iran, Mazāndarān Prov., Najjardeh , ca 36.527N 51.692E.

Type material. Holotype ♀(MHNG): labeled “IRAN 2.7.2014 IM10 Fagetum Najjardeh lat36,52697 lon51,691518 1411NN leg. J.Müller” / Holotype [red] / Persescaphium pari gen.n., sp. n. Löbl & Ogawa, 2016.

Description. Total body length 4.20 mm, length from anterior margin of pronotum to inner apical angles of elytra 3.60 mm, basal width of pronotum 1.80 mm, maximum width of elytra 2.25 mm. Head, pronotum, elytra, ventral side of thorax and most of sternite 1 black, shining. Mouth-parts and antennomeres 1 to 6 light reddish-brown, 7 to 10 black, 11 reddish-brown. Sternite 1 reddish-brown along apical margin. Basal two thirds of sternite 2 blackish, apical third reddishbrown. Sternites 3 to 5 reddish-brown. Exposed tergites and apical sternites yellowish. Coxae, femora and tibiae blackish, trochanters dark reddish-brown, tarsi as antennomeres 1 to 6 light reddish-brown. Frons fnely, irregularly punctate, minimum width between eyes 0.44 mm, 1.8 as large as horizontal eye diameter. Eyes convex, ration vertical/horizontal diameters as 30/23. Length/width ratios of antennomeres as: II 13 /5.5: III 14/4: IV 13/4: V 12/5: VI 10/7: VII 13/11: VIII 12/12: IX 14/13: X 12/13: XI 19/13. Pronotum with weakly sinuate lateral margins, gradually narrowed anteriad, not constricted posterior mid-length, with punctation very fne near anterior and along basal margins, on prevailing surface coarser than on head. Pronotal punctures well delimited, puncture intervals about twice to fve times as large as puncture diameters in middle part of disc; coarse puncture forming one or two irregular rows on antebasal area and several additional coarse punctures near basolateral margin. Pair of macrosetae present 0.10 mm behind anterior margin of pronotum, separated from each other by 0.35 mm. Scutellum subtriangular, with few fne punctures. Elytra widest just posterior basal third, lateral margins rounded in basal third, oblique posterior basal third. Sutural striae shallow, very densely punctate, near base evanescent and indicated by puncture row extending to and along basal margin to form basal puncture row. Elytral disc with seven additional very dense, not impressed puncture rows, fourth puncture row joint to basal row. Outer puncture row closer to lateral margin than to sixth puncture row. Punctation on apical fourth of elytra irregular. Adsutural areas and spaces between puncture rows almost impunctate. Two macrosetae present between third and fourth puncture rows, at level of elytral mid-length, and anterior elytral apical sixth. Macrosetae present along apical and near lateral margins of elytra. Ventral side of thorax lacking microsculpture. Prosternum in middle 0.08 mm long. Prosternal bead indistinct. Metaventrite very fnely and sparsely punctate, with shallow apicomedian impression. Submesocoxal lines punctate. Margin of intermetacoxal process concave. Mesanepisterna parallel-sides, with deep, punctate suture. Sternites with punctulate microsculpture. Tergite 7 not without microsculpture, very fnely punctate, with eight macrosetae. Sternite 1 coarsely punctate; punctures sharply delimited, puncture diameters mostly about as halves of puncture intervals. Following sternites very fnely punctate. Sternites1 to 4 each with single pair of macrosetae. Trochanters each with one macroseta. Protibiae straight, mesotibiae distinctly curved, metatibiae weakly curved. Length ratio of metatarsi as: 35: 44: 25: 20: 60 (in lateral view, Fig. 3 ).

Biology. The species was found on fungi on Fagus orientalis , in a forest at 1411 m altitude.

Distribution. The species is known only from its type locality.

Etymology. The species epithet is the name of descendants of angels in Persian mythology.
