Other material examined: Yemen: 2♂ 3♀, Al Hudaydah prov., Jabal Bura valley forest N. P., 15°52.4–5'N 43°24.6–25.2'E, 240–350 m, 4.xi.2010, J. Bezděk ( JBCB) ; 1♂, Jabal Bura , 14°52'N 43°24'E, 225–600 m, 30.x–1.xi.2005, S. Kadlec ( JBCB) ; 2♂ 4♀, same data but P.

Distribution: Saudi Arabia ( Medvedev 1996), Yemen (Bezděk 2012; present study).

Comparison: The males of Chikatunolepta buettikeri differ from Ch. emir and Ch. millingeni in the presence of subapical vertical lamela on mesotibia ( Figs 20, 21) and the structure of abdomen having short and wide process on ventrite III and missing process on ventrite II ( Figs 13–15). The females are indistinguishable in habitus.

Comments: In the figure plate in the original description of Calomicrus buettikeri, Medvedev (1996: 251) interchanged the drawings of the abdomina of C. buettikeri and C. millingeni . Contrary to the plate legend, his figure 47 pertains to C. buettikeri and figure 49 to C. millingeni . This mistake was adopted by Lopatin (2002, 2006) when describing C. friedmani and C. emir .
