Tuarega insignis (Lucas, 1851)

( Figs. 16 , 110, 120 , 213 )

Material examined. N. AFRICA: Rio de Oro ( Spanish Sahara ), 1926, 1♂ (leg. S. G. Spatz) (AİBÜEM) ; ALGERIA: Algier, El Kantara , 6–7.1932, 1♀ (leg. T. Zekri) (AİBÜEM); Beni Abbés, Sahara Argelino, 1♀ (leg. J. Mateu) (AİBÜEM) ; Algeria, Biskra, 1♂ ( NMW) ; Biskra, 5.1938, 1♂ (leg. M. N. Korsakoff) ( NHMUK) ; Algeria, road to Laghovat, near El Khneg , 26.5.1942, 1♂ (leg. M. N. Korsakoff) ; Algeria, Hoggar Plateau , 1396 m, 10.2.1976, 1♀ nymph (leg. M. N. Korsakoff) ( NHMUK) ; TUNISIA: Nr. Gafsa, 8.4.1 966, 1♀ (leg. G. Popov) ( NHMUK) .

Remarks. Yin & Li (2011) described two species, T. sahara and T. parisi in January of 2011 They distinguished these two species from T. insignis by the wide pronotum, wider than the length of metazona, the median vein combined with cubital vein and the cubital vein with 2 branches. Yin, Huseman & Li (2011) describing one more species of Tuarega , T. ouarzazatensis in July of the same year separated it from T. insignis by the same characters with T. sahara and T. parisi . However, Yin, Huseman & Li (2011) did not mention the paper of Yin & Li (2011) which published by two of them. Massa (2013: 442) synonymized these 3 species, synonymy here fully agreed. In addition to the specimens listed here, more than 50 adult specimens of T. insignis collected from various places of N. Africa were studied in the NHMUK and compared with the diagnostic characters (the width of metazona and the venation of tegmina) of T. sahara , T. parisi and T. ouarzazatensis . The venation of tegmina is strongly variable even in the left and right tegmina of a single specimen. The width and length of metazona are also variable. It is not possible to distinguish a different taxon in the rich material studied using these characters.
