Amberana tripunctata var completa Lallemand, 1949: 70 . Holotype Ƥ (MRAC) examined ( Figs 11–12 , 19 ). Syn. n.

Male genitalia ( Figs 14–17 ). Ventral margin of pygofer with a process oriented posteriorly. Pygofer height: 1.3 mm. Subgenital plates elongated and curved dorsally on apical third, apex pointed. Parameres bearing interiorly in posterior area a spine hooked shaped, dorsal margin presenting a clear dorsal extension. Aedeagus developed anteriorly in two-pointed protrusions, the lower one being larger. Apex of posterior dorsal extension of aedeagus cogged and reaching dorsal margin of pygofer, anterior dorsal extension represents 1/3 length of posterior extension.

Note. The observation of male genitalia is the only way to distinguish for sure this species from A. kraussi . According to Synave (1957) A. bergevini and A. kraussi differ by relative dimensions from the head and the pronotum, A. bergevini being larger proportionally. Some specimens studied in this work are intermediate for those proportions making the identification difficult.

Synonymy. Lallemand (1949) cited for the first and unique time A. tripunctata var. completa in his species table for Amberana . He listed enough characters to distinguish the female holotype of this variety from the female holotype of the species. The shape of the patches on the tegmina ( Figs 18, 19 ), the coloration of these patches and the size and shape of the dimple on the postclypeus were used. For this revision, more material was available for study than it was for Lallemand. The observation of the patches patterns, colour and dimple shows variability within these characters, making it impossible to identify the subspecies. Until now, the presence of 3 colour patches on the tegmina allowed to differentiate A. tripunctata from A. bergevini which has only 2 large patches ( Fig. 20 ). Having had access to more specimens the observation of male genitalia was possible and no difference between the supposed species was visible. The original description of both species was published in the same article in 1920. The morph of A. bergevini holotype is the most common. As first reviser, it was decided to keep this name according to the article 24.2.of the International Code of Zoological Nomenclature. This is why A. tripunctata is synonymised with A. bergevini .

Coloration. A gradient in the pattern of coloration is observed on the tegmina, from two to three patches, from yellow-whitish to orange. Sometimes, the two anterior patches seem to join, giving only one big macula in which a small half moon black patch, along the external margin, can be seen or not. The most posterior patch is always shaped as a stripe (transverse to the tegmina). It can differ in width and can either touch the margins at its apex or not. This last patch can help recognise this species from A. attiei where the described patch is circular and never touches the margins.
