Ammatomus yemenensis Schmid-Egger, 2019: 448 , ♀, ♁.

Diagnosis. Body length: 8.0 mm.

This species is diagnosed by the following characters: gastral T 1 distinctly petiolate, with distinct constriction between T 1 and T 2 ( Fig. 2A ); metanotum ivory, smooth; T 2–4 with complete ivory bands ( Fig. 2A ); T 1 about 1.5× as long as apical width, with two large posterolateral ivory markings a short distance apart, remainder black, posterior margin translucent; S 2 with two small triangular ivory markings posterolaterally ( Fig. 2E ); hind tarsomeres I–III all yellowish to whitish ( Fig. 2A, E ); hind claws black ( Fig. 2E ); T 1 without or with indistinct lateral carina.

Male: Not available.

Material examined: 1♀, Farasan Island Abdulmajeed farm [16 Q 42.07970’N; 42 Q 08.5781’E], 23–30.ix.2022

Distribution: Yemen ( Schmid-Egger 2019), Saudi Arabia (new record).

Comments: Ammatomus yemenensis Schmid-Egger from the Farasan Archipelago is a new record for Saudi Arabia. The characters of the only specimen collected agree well with A. yemenensis in Schmid-Egger’s key (2019: 440, couplet 11). It differs from the Yemeni female in having the pale parts of body ivory white (whitish yellow in Yemeni specimens); antennal flagellum entirely black except last two flagellomeres reddish beneath ( AS 1–3 yellowish white in Yemeni specimens); T 1 1.29× as long as mesoscutum (1.1× mesoscutum in Yemeni specimens). It also agrees with Schmid-Eggers’ (2019: 456, figs 41–44).
