Diagnosis. Body shape, color and markings of T. angustistriatum male are very similar to T.bombylans (Fabricius, 1805) ( figs 51–54 ), but clearly can be distinguished from it by the hind tibia black anterolaterally at least third of the length of the tibia ( fig. 48 ) (in T. bombylans , hind tibia without black mark anterolaterally, or with black mark occupying no more than one sixth of the length of the tibia, as on fig. 52 ) ( Speight & Sarthou, 2017). Additionally, T. angustistriatum male can be distinguished from T. bombylans by: mid tibia yellow with blackish incomplete ring (mostly expressed on the posterior side) just below the middle of tibia not less than a third of the length of the tibia ( fig. 49 ) (in T. bombylans , mid tibia entirely yellow, as on fig. 53 ), a third of the hind femur at the apex mostly with black macrotrichia ( fig. 50 ) (in T. bombylans , a third of the hind femur at the apex mostly with pale macrotrichia, as on fig. 54 ). Female can be distinguished by the same characters as the male except mid tibia with less expressed dark ring.
