Body Length: ♀: 13 mm; ♂: 8.0- 11 mm.

Brief description. Female ( Figs 9A, B View FIGURE 9 , 10 View FIGURE 10 A-C, 12A-D, 13A-C)): Body black, with yellow and reddish brown to ferruginous. Clypeus with minute, emarginate lamella just above free margin, free margin with four distinct teeth ( Figs 10A View FIGURE 10 , 12B View FIGURE 12 ); propodeal enclosure smooth, with superficial punctures laterally, separated by alutaceous interspaces ( Fig. 13A View FIGURE 13 ); hindcoxa with sharp keel along its inner side; pygidial plate relatively large, broad at base, narrowed towards apex, narrowly rounded apically, superficially rugose, with dense upwardly curved pale setae laterally ( Fig. 10C View FIGURE 10 ).

Male ( Fig. 11 View FIGURE 11 A-E): With reduced yellow and red areas ( Fig. 11A View FIGURE 11 ); clypeus bicolored, with straight apical margin ( Fig. 11B View FIGURE 11 ); scutum moderately punctate ( Fig. 11C View FIGURE 11 ), scutellum smooth ( Fig. 11C View FIGURE 11 ); clypeal brush extending along its lateral lobes ( Fig. 11B View FIGURE 11 ); T 6 without lateral spine ( Fig. 11E View FIGURE 11 ), S 6 with lateral, finger-like process ( Fig. 11E View FIGURE 11 ).

Comments. This species was previously misidentified as C. eugenia Schletterer, 1887 , it was corrected to C. hathor by Pulawski (1983). Our female specimens differ from that of Pulawski’s holotype in having the pale body colour yellow ( Figs 9A, B View FIGURE 9 , 10A View FIGURE 10 ) (ivory white in holotype female, Fig. 12A, B View FIGURE 12 ). Characters of female and male specimens agree with Schmidt’s key (2000: 89, 90, couplets 4, 10, respectively). Cerceris hathor closely resembles C. tricolorata , from which it differs by the following: scutum sparsely punctate ( Fig. 13A View FIGURE 13 ) (scutum densely punctate in C. tricolorata ( Fig. 18B View FIGURE 18 )); male and female propodeal enclosure smooth and shiny ( Fig. 13A View FIGURE 13 )) (male propodeal enclosure coarsely longitudinally ridged in C. tricolorata ( Fig. 21B View FIGURE 21 ); gastral T 1 short and globular ( Figs 9A View FIGURE 9 , 12A View FIGURE 12 ) (distinctly long in C. tricolorata ( Figs 18C View FIGURE 18 , 20A View FIGURE 20 )); T 2 of the male normal ( Fig. 11A View FIGURE 11 ) (male T 2 long and slightly constricted at base in C. tricolorata ( Fig. 20A View FIGURE 20 )); male S 6 only with posterolateral spine or process ( Fig. 11E View FIGURE 11 ) (both T 6 and S 6 of the male with posterolateral process in C. tricolorata ( Fig. 21D View FIGURE 21 )); T 4 apically and T 5 wholly or partly whitish ( Fig. 12A View FIGURE 12 ) (T 4 entirely reddish brown in C. tricolorata ( Fig. 18B View FIGURE 18 )). The male also agrees with Guichard’s key (1993: 165, couplet 27 as C. eugenia ) in which S 6 only has lateral spine ( Fig. 11E View FIGURE 11 ).
