Chaetocladius berythensis sp. n.

Though C. berythensis sp. n. shows, as illustrated in Figs 1 I-N, 2 A-C, a close morphological similarity with the laminatus -group (shape of virga, inferior volsella, and gonostylus), some other unusual relevant characters (Figs 1 B-C, G-H, M-N; 2 B-C) found in the male adult (structure of sensilla coeloconica on palpomere 3, shape of the dorsal hump on tergite IX, sinuous crista dorsalis consisting of low proximal lobes ending with a larger distal tooth located close to the megaseta, posterior margin of gonostylus with a triangular bare and hyaline expansion located medially) lead us to regard this new species to be a local glacial relict representative of the ‘Levantine Province’. As reported by Moubayed-Breil (2017) and Moubayed-Breil & Bitusik (2019) and based on the previously cited characters, the laminatus -group currently includes 6 known species from Europe and neighbouring areas: C. bitusiki Moubayed, 2019; C. coppai Moubayed-Breil, 2017; C. elisabethae Makarchenko & Makarchenko, 2018; C. guisseti Moubayed, 2017; C. laminatus Brundin, 1947; C. purbeckensis Langton & Armitage, 2010 . Consequently, the description of C. berythensis sp. n. increases the total number in the laminatus - group to 7.
