Diagnosis. Recognized by the following combination of characters: total length male 2.4–2.9, female 2.6–3.0; general coloration whitish to pale brown; vertex with two oval pale brown spots at sides of midline; postocular area of vertex with darkened base and wide whitish edging behind eye; antennal segment II dark brown with very narrowly whitish base and apex; pronotal collar uniformly whitish; calli with orange tinge and sometimes with narrow pale brown marking along posterior margin; disc of pronotum behind calli pale brown, irregularly colored; scutellum dark brown, with apically narrowing ivory stripes at sides; tibial spines without spots at bases ( Fig. 2 ); spatulate apex of left paramere distinctly curved near midline, with large, posteriorly pointed dorsal crest running on apical two-thirds of apical process ( Fig. 10 ).

This species readily differs from congeners in the generally whitish coloration with reduced dark color pattern of the head and pronotum. Somewhat similar to D. globulifer in the shape of the left paramere but paramere body in D. montandoni is moderately swollen and apical crest is basally rounded.

Distribution. This species was originally described from Romania and subsequently found in several localities in central Turkey ( Hoberlandt 1956; Lodos et al. 2003), Ukraine (northwestern shore of the Black Sea in Odessa Prov.), and northern Crimea ( Kiritshenko 1951). The species is currently unknown from the Caucasus.

Host and habitat. In Ukraine, D. montandoni inhabits Gypsophila sp. ( Caryophyllaceae ) growing on salt dunes along seacoast ( Kiritshenko 1951).
