Trygetus susianus Zamani & Marusik, 2021: 184 View in CoL View Cited Treatment , figs 26D, 27E–H (♀).

Material examined. IRAN: Khuzestan Province: 1♂ ( MHNG), north of Andimeshk , 32°41'N 48°15'E, 17.05.1974 (A. Senglet) GoogleMaps .

Diagnosis. The female of this species differs from the congeners occurring in the region by having indistinct epigynal fovea (vs. transverse or triangular) and a pair of longitudinal sclerotizations in the center of the epigynal plate ( Fig. 6G–I View FIGURE 6 ). The male of T. susianus differs from the congeners occurring in the Mediterranean by the nonfilamentous embolus (vs. filamentous in other species; cf. Fig. 10B View FIGURE 10 and Levy 1992: figs 35, 43). It differs from T. nakhchivanicus sp. n., the most similar species, by the shape (i.e. not sharply pointed) and size of RTA (shorter than tibia vs. longer), and the tegular apophysis lacking lobes (cf. Fig. 9D and 9B View FIGURE 9 ).

Description. Male. Habitus as in Fig. 5E View FIGURE 5 . Total length 1.85. Carapace 0.86 long, 0.58 wide. Eye sizes:AME: 0.08, ALE: 0.04, PLE: 0.04, vestigial PMEs seem present. Carapace, sternum, labium, chelicerae and maxillae yellowish; carapace with several rows of pores on pars thoracica. Legs yellowish, without annulations. Abdomen with dorsal and ventral scuta, dorsally pale beige, ventrally yellowish. Spinnerets pale, uniform in color. Measurements of Fe: I: 0.55, II: 0.50, III: 0.46, IV: 0.62, rest of the segments missing.

Palp as in Figs 8A–E View FIGURE 8 , 9C–D View FIGURE 9 , 10A–E View FIGURE 10 ; femur almost 3 times longer than wide, 1.2 times shorter than cymbium; patella as long as wide; tibia shorter than wide, RTA consisted of ventral and retrolateral parts divided by furrow (Rf, Fig. 8E View FIGURE 8 ), ventral part rounded, retrolateral part diamond shaped; cymbium unmodified, 2 times longer than wide; bulb almost round, with distinct subtegulum (St), tegular apophysis (Ta) hook-like, lacking distinct lobes, with deep groove ( Fig. 8B View FIGURE 8 ); embolus (Em) broad, originating at about 9 o’clock position, terminal part complex with several outgrowths ( Fig. 10A–E View FIGURE 10 ).

Female. Epigyne as in Fig. 6G–I View FIGURE 6 ; for the description, see Zamani & Marusik (2021). In the original description, the vestigial PMEs were overlooked ( Zamani & Marusik 2021: fig. 26D).

Comments. Although the male specimen described here was collected along with the holotype female, for some reason it was deposited in a separate vial and located only after the species was described.

Distribution. Known only from two localities in Khuzestan Province, southwestern Iran.
