Diagnosis. Based on the published description of C. bolkarensis (KARTAL 1982), C. marmoratus can be distinguished from C. bolkarensis by the characters given in the key above.

Redescription. Measurements. Body length: male 3.9–4.1 mm; female 4.0– 4.5 mm. Crown twice wider than eye width, 0.5 mm long medially and 0.4 mm broad between eyes. Pronotum wider (0.7 mm) than long (0.5 mm). Combined length of mesoscutum and scutellum 0.4 mm (as wide as long). Forewing length 3.1 mm.

Coloration and structure. See the generic redescription. Ecology and biology. This species was commonly found in the Rawdhat Khorim (= Rhodet Khorim) National Park situated in the Central KSA (Fig. 53), which has a diverse flora of 153 plant species within 32 families (ALFARHAN 2001). Concavifer marmoratus was collected there on Lycium shawii Roem. & Schult. (Solanaceae) but there were many other plant species in the surroundings, e.g. Acacia gerrardii Benth. (Fabaceae) and Rhazya stricta Decne. (Apocynaceae) . No further biological information is available and no assessment of any economic importance of Concavifer has been reported yet.

Distribution (Figs 51‒52). Iran (DLABOLA 1960), Kingdom of Saudi Arabia (DLABOLA 1979, this paper), Mongolia (EMELJANOV 1972), Kazakhstan (ZHURAVLEV 1991), Palestine (LINNAVUORI 1962).

Remarks. Concavifer nativus Zhuravlev, 1991 and C. sagittatus Emeljanov, 1972 are treated herein as new subjective junior synonyms of C. marmoratus . EMELJANOV (1972) and ZHURAVLEV (1991) distinguished their newly described species from C. marmoratus based only on Dlabola’s original illustrations of the stylus. However, DLABOLA (1960) did not illustrate the stylus structure correctly, which is demonstrated here by a study of paratypes from Iran and additional specimens from KSA originally identified by Dlabola. These specimens, as well as numerous additional specimens from KSA, Iran and Oman fully agree with characters specified in the original descriptions of C. nativus and C. sagittatus .
