Chlorita cf. tamaninii Wagner, 1959 (Fig. 4)

First record from Switzerland: Ticino, Ludiano, Ronco Pizzotti, vineyard, [46 ° 24 ’ 57.92 ’’ N; 8 ° 58 ’ 11.39 ’’ E, 459 m], 2 ♂♂, 1 ♀, 21.06. 2011, D-vac, leg. & det. Valeria. Trivellone

Distribution in Europe:Italy, Switzerland.

Remarks:In total 24 species of the genus Chlorita Fieber are known from the Palaeartic region. Four of them: C. subulata (Ribaut, 1933), C. viridula (Fallen, 1806), C. tamaninii Wagner, 1959 and C. paolii (Ossiannilsson, 1939) belong to the Chlorita viridula species group and are closely related. Wagner (1959) published a key to distinguish the above-mentioned species. Up to now, in Switzerland only C. viridula (Ribaut 1933, Cerutti 1939) and C. paolii (Trivellone &Pollini Paltrinieri 2011) were recorded. In 2011, the first author had collected specimens with aedeagus morphological characteristics quite different from C. viridula and C. paolii. According to the key after Wagner (1959), two main subgroups of species were recognized based on the characteristics of the appendages of the aedeagus: appendages without ablunt tooth and convergent in the viridula-subulata subgroup; and appendages with ablunt tooth and divergent in the paolii-tamaninii subgroup. The appendages of the examined specimens do neither coincide perfectly with the first, nor with the second subgroup. The following description of aspecimen is proposed as reference to further collections.

Determination:The genital plate with parameres and the appendices of the anal tube are illustrated in Figs 4 A and 4 B, respectively; they are similar to C. viridula after Le Quesne &Payne (1981). In the male, aedeagus with apair of recurved appendages, longer than main stem, without tooth along outer margin; but hardly S-shaped in the middle (Fig. 4 C) and ending in sharp-hooked apices (Fig. 4 D).
