Dicyphus (Brachyceroea) digitalidis Josifov, 1958: 271

Material examined: ABKHAZIA: Sukhum distr. , Tsebelda, 1♂ 1♀ VIII–IX 1931 , Voronov. BULGARIA: Rila Mts, 2♂ 4♀ 27 VIII 1961, Josifov .

Diagnosis. Recognized by the following combination of characters: always macropterous, total body length male 3.8–4.5, female 3.9–4.4; dark setae on head without brown spots at bases; antennal segment II dark brown with narrowly whitish base, apex and middle one-third; pronotal collar whitish, with four round dark brown spots at bases of setae; pronotum with ivory to whitish yellow midline interrupted between calli and usually not reaching posterior margin; calli whitish to ivory, with brown color pattern composed of dense, variously shaped and confluent stripes, never entirely brown; scutellum whitish, with two dark brown, sometimes apically confluent stripes at sides of whitish midline; tibiae with dark brown spots at bases of tibial spines ( Fig. 2 ); left paramere very large, thin and slender, with moderately swollen body; spatulate apex with finely upturned, rounded, flat apex and well developed, basally step-shaped crest ( Fig. 10 ); genital capsule with large transverse crest supporting left paramere.

Refer to diagnosis of D. albonasutus for discussion of the distinctive features of this species.

Distribution. The species was originally described from Bulgaria and subsequently found in Macedonia ( Josifov 1986) and several Mediterranean provinces of Turkey ( Lodos et al. 2003). Here we report it from the Caucasus (Abkhazia) for the first time.
