Holotype: ♂ (White label, black handwritten): <23.II 1942/Buq Buq/P.J. Gent/Egypt> (White label, black typewritten and black handwritten): <Brit. Mus./1952-180> (White label, black typewritten): <BMNH {E}/UIN989817>. (ae) Deposited in BMNH [examined].

Paratypes: (2 ♂), Egypt, Buq Buq: 14.11.1942, P.J. Gent, {E}/UIN989815 (♂); Egypt, E. of Buq Buq, 14.11.1942, P.J. Gent, {E}/UIN989815, Brit. Mus.952-180 (♂) (BMNH).

Diagnosis.

Large species with 20-24 white rounded and elongated elytra spots; six white marginal extensions, extension I elongated. Elytra wide, lateral margin strongly and continuous rounded. Aedeagus elongated, thin and with apex slightly bent ventrally (Fig. 9d).

Comparisons.

Graphipterus magnus sp. n. resembles G. heydeni from which it differs mainly by elytra shape and pattern, and aedeagus shape (see comparisons in G. heydeni ).

Description.

BL male: 18.3-20.1 mm, BL female: unknown. Average 19.4 ± mm.

Head slender; HW/PW: 0.72; EYL: 1.7 mm; EYL/EL: 0.17. Frontal ridge well developed. In male, apical white frons stripes slenderer than exposed frons (cf. Fig. 4a). Pronotum cordiform; PL/PW: 0.62; BPW/BPW/PW: 0.68; posteromedially concave and without white margin; white lateral margin as wide as antennomere I long.

Elytra wide, rounded, rounded-like, humeri strongly narrowed; EL: 9-10.7 mm, average 9.7 mm; EW: 8.5-9.0 mm, average 8.7 mm; EL/EW: 1.1. Lateral cross section quite flat. Scales black, disc not visible between them (cf. Fig. 6a). White lateral margin nearly as wide as antennomere I long and with six extensions; extensions I slightly elongated, wider close to the margin; extensions II and III in front of middle. White posterior margin as wide as lateral margin or wider, sutural gap slenderer than lateral margin. Disc usually with 20 (rarely up to24) spots; anterior pair of spots rounded, wider than extension I, 6-8 spots adjacent elongated and parallel to suture, posterior pair of spots rounded, additional 1-3 small spots frequently present laterally to posterior ones. Apical sinuation strongly developed, apex protruded, almost rectangular, only slightly rounded at most distant tip (Fig. 7a). Suture conspicuous.
