Cephennium constrictum View in CoL nov.sp. ( Figs 1 View Figs 1-6 , 27-30 View Figs 25-33 , Map 1 View Map 1 )

Type material: Holotype ♂: "E. Umg. Barcelona, Sierra del Cadi , 1700-2000 m, Col de Pal, 31.III.1994 Assing / Holotypus ♂ Cephennium constrictum sp. n. det. V. Assing 2020" ( cAss) . Paratype ♂: same data as holotype ( cAss).

Etymology: The specific epithet (Latin, adjective) alludes to the subapically constricted ventral process of the aedeagus (ventral view).

Description: Body length 1.6-1.7 mm. Habitus as in Fig. 1 View Figs 1-6 . Body reddishbrown to dark-brown. External and male secondary sexual characters as in C. kiesenwetteri .

♂: aedeagus ( Figs 27-30 View Figs 25-33 ) 0.62 mm long; ventral process rather weakly curved in lateral view, medially distinctly dilated and subapically strongly constricted in ventral view; internal sac apically with a pair of clusters of long thin spines.

Comparative notes: As can be inferred from the highly similar external and male sexual characters, this species is very closely related to C. kiesenwetteri , from which it is distinguished only by the less strongly curved (lateral view), medially strongly dilated, and subapically strongly constricted ventral process of the aedeagus, as well as by the slightly longer apical spines in the internal sac of the aedeagus. For comparison, the aedeagus of C. kiesenwetteri is illustrated in Figs 25-26 View Figs 25-33 .

Distribution and natural history: Thetypelocalityisapassin Sierra del Cadi, approximately 100 km to the north-northwest of Barcelona ( Map 1 View Map 1 ). The specimens were sifted from litter and moss in north slopes with pine and juniper at altitudes between 1700 and 2000 m.
