Description.

In addition to generic characters, with the following characteristics.

Male genitalia. Subgenital plates with rounded apex (Fig. 38 View Figures 38–52 ); connective linear, contiguous (Fig. 40 View Figures 38–52 ); apodemes broad, extending to mid-length or the end of second abdomen segments, apodeme width 1.5 times the distance between each apodeme, posterior margin angled externally and tapered internally (Fig. 54 View Figures 53–74 ); aedeagus with only dorsal process, both slightly curved inward preapically but not bent, aedeagal shafts with diverging branches, ratio of distance between two shafts at mid-length to tip length 5/9, straight, shorter than basal process, as wide as basal process, basal process extending close to shafts branches, pointed; phallobase not inflated (Figs 23 View Figures 23–37 , 24 View Figures 23–37 ).

Female genitalia. Female 7th sternite 2.5 times as broad at base as long medially, posterior margin concave, acutely sinuous with V-shaped notch in middle, posterolateral angles rounded (Fig. 55 View Figures 53–74 ); first valvula slightly convex; second valvula gradually tapered apically with rather small and serrate teeth on dorsal surface (Figs 56 View Figures 53–74 , 57 View Figures 53–74 ).

Distribution.

Azores, Armenia, Austria, Belgium, Canary Islands, Egypt, European Russia, France, Germany, Italy, Kazakhstan, Kyrgyzstan, Libya, Morocco, Sardinia, Sweden, Tadzhikistan, Turkmenistan, Uzbekistan ( Metcalf 1967); Saudi Arabia (present study) (Figs 75 View Figures 75–79 , 76 View Figures 75–79 ).

Ecology and biology.

This species is widespread and common in southwestern KSA and is often associated with the wadies of Asir Province, a habitat that has one of the most diverse floras of the region. In five of these Asir wadies and also in Baha Province, KSA, O. heydeni became common in March, particularly in Wadi Qounonah. Although Opsius is host-specific on Tamarix spp., this species was collected from other plants at these sites including Acacia spp. ( Fabaceae ) (Figs 77-79 View Figures 75–79 ).

Diagnosis.

Opsius heydeni is similar to O. wilsoni sp. nov. but males of the species can be distinguished easily by the aedeagus and dorsal process slightly curved inward preapically, aedeagal shafts with diverging branches and straight, shorter than basal process, as wide as the basal process, ratio of distance between two shafts at mid-length to tip length 5/9; and the basal process extending close to shafts branches.
