Reichardtiolus perses sp. n. Figs 48-61

Type locality.

Iran, Kerman, Talab.

Type material examined.

Holotype, male, side-mounted on triangular point with male genitalia extracted and glued to the same triangular point as the specimen, left protarsus and left mid-leg missing, piece of left elytron from the elytral flank along the elytral base towards the fourth elytral stria chipped out; with the following labels: “♂” (printed); followed by: "Kerman: str. Talab / 19-20.i.[19]01 / N. Zarudny" (printed-written label in Russian); followed by: "Coll. Semenov-Tian-Shansky" (printed); followed by: "ZOOLOGICAL / INSTITUTE RAS / ST. PETERSBURG" (yellow label, printed); followed by: " Reichardtiolus perses / sp.nov. HOLOTYPE / Det. T. Lackner 2013" (red label, printed) (ZIN). Paratypes: 1 ♀, ibid (sputter coated with gold) (ZIN); 1 ♀, ibid, but 20.i.[19]01, with an additional written-printed label: " Exaesiopus / duriculus Rtt. / Reichardt det." (TLAN).

Diagnostic description.

Body size: PEL: 2.50-3.75 mm; APW: 0.75-1.15 mm; PPW: 1.90-2.75 mm; EW: 2.00-3.00 mm; EL: 1.75-2.50 mm. Body in general (except for Reichardtiolus pavlovskii ) larger than the rest of congeners, cuticle similar to that of Reichardtiolus duriculus ; legs, antennae and mouthparts chestnut brown. Mouthparts similar to those of Reichardtiolus duriculus , mentum on anterior margin deeply emarginated medially (Fig. 49). Clypeus and frons (Fig. 48) coarsely and densely punctate; frontal stria weakened medially; frontal disk with low protuberances and shallow depressions, very coarsely and densely punctate, especially medially; clypeus margined laterally. Pronotum as in Reichardtiolus duriculus , punctuation medially sparser, punctures weak and separated by several times their diameter. Elytra generally similar to those of Reichardtiolus duriculus ; punctuation of pygydium generally denser than that of Reichardtiolus duriculus (compare Figs 12 and 51). Prosternal process flattened to slightly concave, compressed laterally; carinal prosternal striae approximate, complete; prosternal foveae small. Mesoventrite sub-quadrate, marginal stria anteriorly complete; punctuation sparser than that of Reichardtiolus duriculus , punctures separated by several times their diameter; meso-metaventral stria absent, in case of one specimen substituted by a string of punctures. Metaventrite, metepisternum and abdominal ventrites similar to those of Reichardtiolus duriculus . Legs similar to those of Reichardtiolus duriculus , Reichardtiolus sphingis , and Reichardtiolus aldhaferi . Male genitalia: 8th sternite (Figs 52-53) strongly sclerotized, apically with dense row of short setae and setose velum; 8th tergite apically with deep emargination, on basal half with numerous pores and pseudopores (Fig. 53). Sclerotization of 9th tergite divided medially (as in Reichardtiolus aldhaferi ), on apical half with pores and pseudopores; 10th tergite inwardly arcuate on its basal margin. 9th tergite on apical third with faint, weakly sclerotized bisinuate line, visible only from lateral view (Fig. 59). Spiculum gastrale (Fig. 54) on apical end inwardly arcuate (although not as deeply as with Reichardtiolus sphingis or Reichardtiolus aldhaferi ), with a unique sclerotized ring medially; basal end of spiculum gastrale outwardly arcuate. Aedeagus generally most similar to that of Reichardtiolus sphingis , but blunt apically (compare Figs 31 and 58).

Differential diagnosis.

Reichardtiolus perses is the second largest species of the genus (after Reichardtiolus pavlovskii ) and externally very similar to Reichardtiolus duriculus , Reichardtiolus aldhaferi , and Reichardtiolus sphingis , differing from them mainly by the structure of male terminalia. From the largest species of the genus, Reichardtiolus pavlovskii it differs by the same characteristics as the preceding three species.

Biology.

Unknown, presumably similar to its congeners.

Distribution.

Iran, environs of Kerman (Fig. 72).

Etymology.

The name of this new species means “Persian”. It is a noun in apposition in the nominative singular form.
