urn:lsid:zoobank.org:act:73B78F2A-4907-4334-B475-A59C7CD81063

( Fig. 122 )

Type material: Holotype ♂: “GR – Crete [2], ca 20 km E Ag. Nikolaos, Sfaka , 35°09'00"N, 25°55'26"E, 320 m, soil washing, 24.XII.2017, V. Assing / Holotypus ♂ Cephennium curvatum sp. n. det. V. Assing 2018” ( cAss).

Etymology: The specific epithet (Latin, adjective) alludes to the shapes of one of the pairs of internal structures of the aedeagus.

Description: Body length 1.0 mm; width of pronotum 0.36 mm; width of elytra 0.39 mm. Coloration: body yellowish-red; legs, antennae, and maxillary palpi yellow. Other external characters as in C. sinuosum and C. hamulatum .

♂: aedeagus 0.32 mm long; ventral process apically elongated and acute in ventral view; internal sac with two pairs of sclerotized spines, two of them strongly curved ( Fig. 122 ).

Comparative notes: Aside from the shapes of the median lobe and the internal structures of the aedeagus, C. curvatum differs from the closely allied C. hamulatum and C. sinuosum only by a slightly more slender habitus, from C. hamulatum also by larger size (see measurements). The aedeagus is larger than in all the other named species of the C. sinuosum group, except C. selenanum .

Distribution and natural history: The holotype was collected near Sfaka, East Crete, in a dry stream valley with Quercus ilex and olive trees at an altitude of 320 m by washing soil.
