Description. A small sized Philorhizus (3.1–3.2 mm.) with elytra strongly widened to apex; unicolorous, slightly shining pale yellowish including appendages (Fig. 4.1); microsculpture superficially in male, more evident in female; brachypterous.
Head longer than pronotum (HL/PL: 1.16); eyes slightly convex; temples oblique to neck. Labium convex, with 5 setae; antennomeres 1–3 without hairs except normal setae, 4–11 with fine, long, suberect hairs. Microsculpture consisting of large isodiametric superficial meshes.
Pronotum slightly transverse (PW/PL: 1.3), widest at insertion of lateral seta. Anterior angles not protruding. Lateral sides regularly sinuate to rounded hind angles. Lateral furrow narrow, with 2 setae, one at anterior fourth, the other at the hind angle. Base medially more or less rectilinear, laterally toward hind angles oblique. Middle line well-developed. Basal impression prominent. Microsculpture consisting of superficially transverse, somewhat irregular meshes.
Elytra long-oval (EL/EW: 1.35); humeri strongly rounded; strongly widened to apex, with maximum width at about 1/6 of the apex. Striae 1–3 superficially, other striae evanescent. Scutellar striole present. Marginal umbilicate series consist of 14 setigerous pores. Microsculpture consisting of superficial isodiametric meshes.
Legs metatibia in females slightly bent, in males straight; meso- and metatarsi with long claws with 2–3 small dents; meso- and metatarsomere 1 about the same length as tarsomere 5.
Ventral side with wide ligula, slightly rounded at apex; mentum without tooth. Anal segment with 2 setae on each side, segment 4–5 with 1 seta in middle on each side.
Microsculpture consists of superficially transversal meshes; more evident on anal segment.
Median lobe (Fig. 4.2) relatively stout, 0.84 mm long, apex pointed in lateral view. Endophallus with two twisted bands of scales and spines, the middle band more extensive than the apical one.
Comparative notes. This wingless species resembles the mono-coloured species such as Philorhizus tinauti Anichtchenko, 2005 or P. alpinus Meschnigg, 1934 from the West Palearctic due to its yellow colour. However, the combination of features and especially the structure of the endophallus are different from all other species of this genus.
Distribution. Iran (Kerman / Kuh-e Bahr Aseman).
Habitat. The type specimens were collected in sub-alpine grasslands interspersed at lower elevations with shrubberies. This species is uncapable of flight, hence its distribution area is certainly restricted.
