Lachnus pallipes ( Hartig, 1841)

( Figs 15–19 )

Material examined: Macedonia: Southeastern region, Radoviš municipality, Plačkovica Mts, brook in a beech forest beneath Beli Kamen resorts, beaten from littoral Dryopteris sp. , loc.2017/7, 1335 m, N41°44.67’ E22°30.35’, 5.x.2017, leg. Péter Juhász, Tibor Kovács, Dávid Murányi: viviparous alate female (AP 41, on slide); Eastern region, Vinica municipality, Plačkovica Mts, valley of the Lumen (Lomija) Stream beneath Mt. Lisec, beaten from Fagus sylvatica L., loc.2017/8, 1170 m, N41°45.85’ E22°30.95’, 5.x.2017, leg. Péter Juhász, Tibor Kovács, Dávid Murányi: viviparous alate female (AP 35).

Diagnosis: Colorful Lachnus ; wings with distinct pattern, slightly bent cubital veins and Rs cell clear only in the basal third, basal dark stripe wider than following clear stripe; antenna and legs with fine, very long hairs; siphunculi relatively small and pale but surrounded by relatively large sclerite; secondary rhinaria on antennal segments: III 8–10, IV 2, V 1.

Distribution and ecology: A widespread but uncommon European species, in the Balkans it was known only from Bulgaria and Greece. This is the first species of the tribe Lachnini Herrich-Schaeffer, 1854 reported from Macedonia.

Holocyclic and monoecious on Quercus and Fagus , usually on older branches and stem but may retreat on roots during summer. Both specimens were found solitary in old beech forest, the one beaten from ferns must be accidental migrant.
