Acthortia frontata Kröber, 1912: 30 .

Gyrophthalmus khedivialis Becker, 1912 syn. nov.

Type material. Acthortia frontata (Kröber, 1912) : Holotype female, "Tourrah-Ägypten" (NMW) ( Fig. 1 View FIGURES 1, 2 ).

Other specimens examined. Kom-Osheim 1.VIII.1953 (1 male) (ASUC); Mansouria 13.IX.1924 (1 female); Giza 22.IV1935 (1 female); Fayoum 23.IV.1943 (1 male), Fayoum Tamiyah 31.III.1947 (2 males), Fayoum Elathar 12.III.1950 (1 male); Dahshour 20.VIII.1950 (1 female) (CUC); Mansouriah 4.VI.1933 (1 female) (MAC); Abu Rawash 19.IX.1924 (1 male) (AZUC).

Remarks. Actorthia khedivialis (Becker, 1912) is synonymized with A. frontata (Kröber, 1912) based on examination of the male type specimen of the former (recently discovered in the CUC) and the female type specimen of the latter species (NMW), in addition to both sexes of old Egyptian material. On the male type specimen of A. khedivialis there are three rectangular labels ( Fig. 2 View FIGURES 1, 2 ): Type [red label, printed, black ink] / Gyrophthalmus khedivialis B. [handwritten, black ink] det. Becker [printed, black ink] / 30/V/06 Cairo [handwritten, pencil]. The type specimen of A. frontata , has six labels ( Fig. 1 View FIGURES 1, 2 ): the first two labels are " type labels", Holotype [circular white paper with red margin], Type [rectangular red label, printed, black ink, all caps] / the second two labels are "determination labels" Actorthia frontata Kröb. [handwritten, black ink] O.Kröber det. 1912 [printed, black ink, the year is corrected with handwriting], Actorthia frontata Kröb. Ƥ [handwritten, black ink] Lyneborg det. 1975 [printed, black ink, 75 handwritten] / the last two labels are "locality labels" Tourrah [printed, black ink], Aegyptus, Schmkn. 97 [printed, black ink].

We discovered two male specimens of Actorthia frontata (Kröber) which were collected from Giza 7.IV.1922 (Kröber det. 1923) and Marg 1.IV.1923 (Kröber det. 1923) and another specimen of Actorthia khedivialis (Becker) which was collected from Barrage 10.IX.1922 (Kröber det. 1923), all of them incorrectly bearing type labels and deposited in ESEC but subsequently destroyed by dermestid beetles.
