Medon carpathius ASSING   nov.sp. ( Figs 23-30 View Figs 23-30 )

T y p e m a t e r i a l: Holotype 3: " Greece: Karpathos [10], W Spoa, 35°38'42''N, 27°07'56''E, 210 m, stream valley, sifted, 25.XII.2015, V. Assing / Holotypus 3 Medon carpathius   sp.n. det. V.

C o m m e n t: The unsexed paratypes collected by J. Frisch have my identification label " Medon cerrutii COIFFAIT   , det. V. Assing 2006 " attached to them. The specimens recorded from Karpathos as M. cerrutii COIFFAIT, 1976   by ASSING (2007a) refer to M. carpathius   .

E t y m o l o g y: The specific epithet is an adjective derived from Carpathus, the Latin name for Karpathos.

bars: 23: 1.0 mm; 24-29: 0.2 mm; 30: 0.1 mm. D e s c r i p t i o n: Body length 4.0- 4.8 mm; length of forebody 2.4-2.6 mm. Size,

coloration, and other external characters ( Figs 23-25 View Figs 23-30 ) as in M. cerrutii   and other species of the M. petrochilosi   subgroup. Distinguished only by the male sexual characters:

3: shapes and chaetotaxy of sternites VII ( Fig. 26 View Figs 23-30 ) and VIII ( Fig. 27 View Figs 23-30 ) similar to those of M. cerrutii   , except for the setae at the posterior margin of sternite VII (median setae shorter; lateral combs usually composed of five setae); aedeagus ( Figs 28-29 View Figs 23-30 ) approximately 0.6 mm long; apex of ventral process and apical internal structures ( Fig. 30 View Figs 23-30 ) of distinctive shapes.

C o m p a r a t i v e n o t e s: Based on the external (punctation and sculpture of head and pronotum) and the male primary and secondary sexual characters, M. carpathius   belongs to the M. petrochilosi   subgroup of the M. apicalis   group. The M. petrochilosi   subgroup previously included eight species distributed in the East Mediterranean, all of them with restricted distributions; for a distribution map see ASSING (2013c). The new species is reliably distinguished from the geographically closest representatives of the M. petrochilosi   subgroup only by the chaetotaxy of the male sternite VII and the morphology of the aedeagus, particularly the shape of the ventral process of the aedeagus in lateral and in ventral view and the shape of the sclerotized apical internal structures. For illustrations of other related species see ASSING (2004a, 2013c). The geographically closest representatives of the M. petrochilosi   subgroup are M. cerrutii   (Crete), M. impar ASSING, 2004   (Rhodos), and M. caricus FAGEL, 1970   (southwestern Anatolia; Greek island Nikaría).

D i s t r i b u t i o n a n d n a t u r a l h i s t o r y: The known distribution is confined to the environs of Spoa and Olympos in Karpathos. The specimens collected in December 2015 were sifted from moist leaf litter in stream valleys. The altitudes range from 210 to 500 m.
