Ghrejyan, T. L., Kalashian, M. Yu. & Shokhin, I. V., 2023, A new species of the genus Glaphyrus (subgenus Eoglaphyrus) (Сoleoptera: Scarabaeoidea: Glaphyridae) from Tajikistan, with notes on G. (E.) turkestanicus, Zoosystematica Rossica (Zoosyst. Rossica) 32 (1), pp. 8-15 : 14

Key to the species of the subgenus Eoglaphyrus

1(4). Larger, body longer than 13.0 mm, wider and more convex ( Figs 4–6 , 8 ). Pronotum wider, with pubescence in male distinctly longer and denser, glabrous area in posterior third of pronotal disc smaller; in female, punctation of pronotum denser, glabrous area smaller. Elytral apices rounded or very slightly angulate in male, and very slightly angulate, without tooth in female. Trochanters slightly longer and narrower, with weakly curved posterior margin ( Fig. 13 ).

2(3). Clypeus square, with clear longitudinal carina reaching transversal carina between eyes. Thick erect setae near anterior angles of pronotum yellowish, only slightly darker than surrounding hairs. Pubescence of elytra rufous. Body length in male 15.8–20.3 mm, in female 13.2–17.6 mm. Endophallus as in Fig. 15........................................ G . (E.) afghanistanicus *

3(2). Clypeus barrel-shaped, with unclear longitudinal carina not reaching transversal carina between eyes. Thick erect setae near anterior angles of pronotum brownish, contrasting sharply with surrounding light hairs. Pubescence of elytra yellow. Body length in male 13.5– 20.4 mm, in female 13.0– 18.2 mm. Endophallus as in Fig. 16.......... G . (E.) turkestanicus

4(1). Smaller, body length 12.6 mm in male, 10.8 mm in female, narrower and less convex ( Figs 1, 4 , 7 ). Pronotum narrower, with pubescence in male distinctly shorter and sparser, glabrous area in posterior third of pronotum larger; in female, punctation sparser, glabrous area larger. Elytral apices protruded into short, smoothly emerging tooth in male and protruded into distinct blunt tooth in female. Trochanters shorter, with posterior margin slightly convex ( Fig. 13 ). Endophallus as in Fig. 17........ G . (E.) mardjanyanae sp. nov.
