Comparative diagnosis

The new species is similar to Hecabalodes tadzhicus Tobias, 1964 from Tajikistan and * Turkmenistan (1 ♀, Turkmenistan, Kugitang-tau Ridge [= Koytendag], Khodzhaifilata [near Shalkan Village], 19.v.1982, Belokobylskij [leg.]; ZISP), but differs from it in having the vertex densely and coarsely transversely undulately striate with reticulation (only densely granulate in H. tadzhicus ), notauli complete and rather distinct (almost absent posteriorly in H. tadzhicus ), precoxal sulcus mainly very shallow (entirely rather deep in H. tadzhicus ), second radial abscissa (3-SR) of fore wing distinctly evenly curved (almost straight or weakly and not evenly curved in H. tadzhicus ), metacarpus (1-R1) distinctly shorter than distance from apex of radial (marginal) cell to apex of wing (almost equal to it in H. tadzhicus ), and medial (basal) cell of fore wing almost glabrous or partly with very short setae (rather distinctly setose by medium length setae in H. tadzhicus ).

Etymology

From the Latin word ‘ maculatus ’ (‘spotted’), because the fore wing in this species has numerous dark spots.
