Etymology: The specific epithet is an adjective derived from the Latin noun sagitta (arrow) and alludes to the shape of the apical internal structure of the aedeagus, which somewhat resembles an arrow head.

Description: Body length 1.0- 1.1 mm. Eyes composed of approximately five ommatidia without, or with weak, pigmentation. Other external characters as in C. aciferum .

♂: protibia unmodified; metaventrite with extensive median impression; aedeagus ( Fig. 44 ) 0.33-0.35 mm long; ventral process apically truncate; internal sac with apico-median structure shaped like an arrow head; paramere thin, apically not reaching apex of median lobe and with short apical seta.

Comparative notes: Among the species of the C. jonicum group, C. sagittatum is characterized particularly by the shapes of the internal structures of the aedeagus. Regarding the size of the aedeagus, this species is most similar to C. aciferum , from which is distinguished above all by an apically much less acute apico-median internal structure.

Distribution and natural history: Thespecimensweresiftedin various forest habitats in Ipiros, Northwest Greece.
