Type species: Telephorus insipidus Fall, 1907 Description. Male. Alate, body elongate ( Fig. 1A ). Head transverse, slightly wider than pronotum. Eyes moderately large, spherical. Gular sutures distinct, broadly separated. Ultimate maxillary palpomere relatively small; ultimate labial palpomere hardly longer than wide; ultimate maxillary and labial palpomeres dissimilar in size and shape ( Figs 2A , 5K, L ). Antenna 11-segmented, filiform, long, almost attaining to elytral apices; antennomeres 4-11 with tiny round glabrous (presumably pheromonous) areas; pedicel (antennomere 2) ca 3 times shorter than antennomere 3; antennal pubescence short and semi-erect ( Fig. 1A ). FIGURE 1. General appearance of Podistra species , males. A— P. ( Pidostria ) insipida ; B— P. ( Absidia ) schoenherri (Moscow Oblast); C— P. (s. str.) alpina (Dagestan); D— P. ( Hemipodistra ) birnbacheri (Obir, Austria); E— P. (s. str.) unicolor (Abkhasia) ; F— P. (s. str.) prolixa (Morteratsch V., Switzerland). Scales 1.0 mm. (B, C and E from Kazantsev , 2022 ). Pronotum elongate, rounded anteriorly, almost straight at sides and slightly concave posteriorly; sides inconspicuously widened before anterior angles; acute posterior angles small and inconspicuous ( Fig. 1A ). Scutellum triangular ( Fig. 1A ). Elytra elongate, entire, covering abdomen, with indistinct longitudinal costae; elytral pubescence dual, with denser short and almost decumbent underlying vestiture and sparser relatively long erect hairs ( Fig. 1A ). Legs long and slender; femurs and tibiae straight and narrow, subequal in length ( Fig. 1A ); tibial spurs relatively short, subequal in size and shape ( Fig. 2A ); tarsi long, tarsomeres 1–3 narrow, tarsomere 4 deeply cleft; protarsal claw with prominent, broad, oval basal dent, meso- and metatarsal claws simple ( Figs 2C–E ).

( Pidostria ) insipida , terminal tarsomeres of protarsus; D—same, of mesotarsus; E—same, of metatarsus; F— P. ( Absidia ) schoenherri , terminal tarsomeres of protarsus; G—same, of mesotarsus; H—same, of metatarsus; I— P. (s. str.) prolixa , lateral pronotal bordering; J—same, P. (s. str.) piceolineata ; K—same, P. ( s. str. ) alpina . Abdomen with nine ventrites, ventrite 1 broadly interrupted medially by metacoxae; ultimate ventrite distally triangular. Aedeagus elongate, sub-oval with infuscate distally dorsal plate and laterophyses; parameres about as long as the dorsal plate; dorsal plate with prominent semi-triangular incision at distal margin; laterophyses about as wide as the dorsal plate, medially, in apical view, concave and rather distant from the dorsal plate ( Figs 3A–D ). Diagnosis. Podistra subgen. Pidostria subgen. nov. , resembling Podistra s. str. in the shape of the aedeagus ( Figs 3A–D ) can be distinguished from all subgenera of Podistra by the relatively small dissimilar ultimate maxillary and labial palpomeres, with the labial palpomere about as long as wide ( Figs 2A , 5K, L ) (ultimate palpomeres similar in shape and considerably longer than wide in the remaining subgenera), the dual elytral pubescence ( Fig. 1A ) (single layer of long pubescence in the other subgenera) and broad and oval protarsal claw dent ( Fig. 2C ) (protarsal claw simple or with a narrow dent in the other subgenera). Etymology. The name of the new taxon is a slightly modified anagram of the genus name Podistra . Gender feminine.
