Description.

Adult by Loginova (1975 b). The colour of the head, thorax and forewings is much more variable than described by Loginova (1975 b). The dark dots can cover the head, thoracic dorsum and forewings. Dark adults of C. trjapitzini resemble C. hoberlandti . In the forewing, the cells r 1 and r 2 are mostly light (less than half of the cells) in C. trjapitzini but mostly dark in C. hoberlandti . Fifth instar immature (Fig. 6 E ). Dorsal sclerites on the head, thorax and abdomen brown (Fig. 6 E ). Setae on dorsal surface of forewing pads are relatively sparse and short and with almost no sectasetae. Caudal plate with interval II shorter than medial and apical row of setae (Fig. 7 E ). Ventrite bearing the circumanal ring unsclerotised and not clearly delimited anteriorly; venter, therefore, with five transverse rows between abdominal base circumanal ring; transverse row IV of setae on abdominal venter consisting of two uneven rows of variously long setae.

Distribution.

Armenia ( Gegechkori and Loginova 1990), Jordan (misidentified as C. hoberlandti in Al-Khawaldeh et al. (1997) and Burckhardt et al. (2024)); new for Iran ( Tehran, Yazd); Spain.

Host plant.

Populus sp. ( Salicaceae ).

Comment.

Dark adults of C. trjapitzini resemble morphologically those of C. hoberlandti . The two species share identical cytb sequences but differ in the genetic distance in COI (2.6 %) (Table 2 ).
