Comments. All four varieties are just simple colour aberrations of T. fasciata and we conħrm them as its synonyms. Moreover, Antipa fasciata var. infasciata Kocher, 1952 is a junior secondary homonym of Tituboea nigriventris var. infasciata Pic, 1912 .

Tituboea fasciata is similar to T. paykullii , T. laticollis ( Olivier, 1808) and T. femoralis Medvedev, 1962 (cf. Figs 173–178 ). All species are variable in colouration, however T. fasciata has usually orange legs and mandibles which are often black in T. paykullii or always black in T. laticollis and T. femoralis . Morphological characters are constant: i)the left mandible in male of T. fasciata is sharp but simple without or with very short hook-like termination (with hook-like process in T. laticollis and T. paykullii , cf. Figs 179–186 ); ii) the anterior margin of male profemora near the base is without or with very shallow emargination (with deep round emargination in T. paykullii , T. laticollis and T. femoralis ); iii) the propleura glabrous (densely pubescent anteriorly and sparsely or bare posteriorly in T. paykullii , T. laticollis and T. femoralis ); iv) the aedeagus is in lateral view almost straight, ventrally with shallow wide impression reaching basal opening (apical half of aedeagus distinctly S-shaped in lateral view in T. paykullii , apical half straight in lateral view in T. laticollis and T. femoralis ; in all three species ventrally with shallow oval impression medially and two elongate impressions anterolaterally, cf. Figs 30, 32 , 35, 38 ).
