Tachyusa ferialis Erichson, 1839 ( Figs. 29–31)

Tachyusa ferialis Erichson, 1839: 71 .

Tachyusa bicolor Mulsant & Rey, 1875: 407 (synonym confirmed).

Tachyusa (Caliusa) ferialis: Mulsant & Rey, 1875: 410 ; Ganglbauer, 1895: 248; Fenyes, 1920: 173; Bernhauer & Scheerpeltz, 1926: 586.

Type material. Tachyusa ferialis Erichson. Lectotype (here designated): ♂: Hist.­Coll. ( Coleoptera ) Nr. 5331, Tachyusa ferialis Erichson, Sardin., Géné (ZMHB) . Paralectotypes: 2♂♂ and ♀: same data as the lectotype ( ZMHB).

Tachyusa bicolor Mulsant & Rey. Lectotype (here designated): ♂: Provence, le Languedoc, le Roussillon etc. ( MHNL); Paralectotypes: 2♂♂ and 2♀♀: same data as the lectotype ( MHNL).

Taxonomic notes. An examination of the types, particularly the genitalia, revealed that Tachyusa bicolor is without doubt conspecific with T. ferialis and consequently a junior synonym of the latter.
