Type material: Holotype : “ N32°19'32 E35°43'26, Jordan Ajlun, Ajlun Castle 980 m (2), lg. Meybohm 21.2.2014 / Holotypus  Cephennium jordanicum sp. n., det. V. Assing 2020” (cAss).

Etymology: The specific epithet is an adjective derived from Jordan, where this species is at present the sole representative of the genus.

Description: Body length 1.1 mm. Habitus as in Fig. 24 . Punctation of pronotum more distinct than that of elytra. Eyes small, composed of three or four weakly defined ommatidia without pigmentation. Other external and male secondary sexual characters similar to those of other species of the C. corruptum group.

: aedeagus ( Fig. 67 ) 0.24 mm long, broad, and apically truncate; internal sac with two weakly sclerotized apicomedian structures, the lower one fringed with minute spines; paramere apically extending slightly beyond apex of median lobe, with short apical seta.

Comparative notes: Based on the similar shape and internal structures of the aedeagus, C. jordanicum is most closely allied to C. judaeum , from which it is distinguished by the more transverse apical and the more strongly angled subapical internal structure.

Distribution and natural history: The type locality is situated near Ajlun, some 30 km to the south-southwest of Irbid, Northwest Jordan. The holotype was sifted in a pasture woodland at an altitude of 980 m ( Fig. 71 ).
