Femora only slightly darkened. Antennomeres not darkened distally, except weakly darkened eleventh. Legs and antennae lighter brownish, as in H. cagrankaya sp. n. ; contrast to black surface more distinct. Males. Median lobe of aedeagus in ventral view strongly converging apically, apex very shortly rounded ( Fig. 4 ); apex with tip rather pointed in lateral view. Females. See remarks under H. cagrankaya sp. n. Measurements. TL: 3.3–3.4 mm , MW: 1.55–1.6 mm ; TL/MW: 2.13: IO/MP: 0.46–0.48. Distribution. So far known only from the locus typicus near Çamlihemsin in the Rize province, northeastern Turkey (locality 6 in Fig. 13 ). Derivatio nominis. The species is named after our colleague and friend M.
