Etymology: This species is dedicated to my friend and field companion Heinrich Meybohm.

Description: Body length 1.5–1.7 mm. Body pale reddish-brown with short and nearly depressed pubescence; vertex with two longer erect setae.

Head distinctly transverse, nearly 1.5 times as broad as long, and of triangular shape (length 0.22–0.26 mm; width 0.32–0.36 mm); temples obtusely angled, projecting, and apically with a small circular or oval impression. Eyes large, approximately as long as temples in dorsal view, weakly convex, weakly protruding from lateral contours of head. Antenna with three-jointed club, rather short (length 0.55–0.63 mm); antennomeres I nearly twice as long as broad, II slightly narrower, oval, indistinctly oblong, III minute, IV–VII orbicular, VIII weakly transverse, IX–XI broader, IX and X transverse, XI weakly oblong, slightly shorter than the combined length of IX and X.

Pronotum 0.30 mm long and 0.37–0.38 mm broad, slightly longer and broader than head, broadest in the middle, with convex lateral margins, more strongly tapering posteriad than anteriad, with two ante-basal and two lateral foveae; disc with U-shaped impression in posterior half, bottom of this impression and sometimes laterad of this impression with additional foveae.

Elytra short, as long as pronotum and 1.5 times as broad as long (length 0.29–0.34 mm; width 0.44–0.50 mm), with 2–3 basal impressions, discal sulcus reaching middle of elytra; humeral angles indistinctly marked, with more or less pronounced longitudinal impression directed posteriad. Hind wings completely reduced.

♂: metafemora strongly dilated; metatrochanter ventrally enlarged and with flattened margins; metatibia with small apical spine; genital plate (sternite IX) of oval shape; aedeagus ( Fig. 165 ) 0.36–0.40 mm long, occasionally inverted.

Comparative notes: Faronus meybohmi is distinguished from the widespread F. parallelus and from F. distinctus BESUCHET, 1999 (Lesbos, Samos, Rhodos, Southwest Turkey) by distinctly shorter and more transverse elytra, dilated male metafemora, and by the shape of the aedeagus.

Distribution and natural history: The known distribution is confined to the Lefka Ori region, West Crete. The specimens were collected by sifting leaf litter and grass roots at altitudes of 780–1500 m.
