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, 10A) (ivory white in holotype female, Fig. 12A, B). 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) (scutum densely punctate in C. tricolorata (Fig. 18B)); male and female propodeal enclosure smooth and shiny (Fig. 13A)) (male propodeal enclosure coarsely longitudinally ridged in C. tricolorata (Fig. 21B); gastral T 1 short and globular (Figs 9A, 12A) (distinctly long in C. tricolorata (Figs 18C, 20A)); T 2 of the male normal (Fig. 11A) (male T 2 long and slightly constricted at base in C. tricolorata (Fig. 20A)); male S 6 only with posterolateral spine or process (Fig. 11E) (both T 6 and S 6 of the male with posterolateral process in C. tricolorata (Fig. 21D)); T 4 apically and T 5 wholly or partly whitish (Fig. 12A) (T 4 entirely reddish brown in C. tricolorata (Fig. 18B)). 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).
