Camarotoscena hoberlandti Vondráček (1952): 445.

Material examined.

India • 6 ♂, 8 ♀, 4 immatures; Ladakh, Leh ; 34.2167°N, 77.9500°E; 3500 m a. s. l.; 26. vii. 2024; arid, cold desert; on Populus nigra , Salicaceae , leg. C. Haseen; dry and slide mounted, in 70 % ethanol; NHMB . Additional material from Iraq; dry mounted; MHNG.

Description.

Adult by ( Loginova 1975 b). Adults resemble dark specimens of C. trjapitzini . In C. hoberlandti , the cells r 1 and r 2 of the forewing are mostly dark, with pigment covering more than half of the cells. In C. trjapitzini cells r 1 and r 2 are mostly light. Immature mentioned by Tarasi et al. (2006) but not described. Fifth instar immatures (Fig. 6 B ). Dorsal sclerites on the head, thorax and abdomen light (Fig. 6 B ). Setae on the dorsal surface of the forewing pads are relatively sparse and short and with almost no sectasetae. Caudal plate with interval II longer than medial and apical row of setae (Fig. 7 B ). 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.

Iran, Iraq, Turkey, Turkmenistan ( Vondráček 1952; Loginova 1975 b; Gegechkori and Loginova 1990; Burckhardt and Lauterer 1993; Tarasi et al. 2006); new for India (Ladakh).

Host plant.

Populus nigra L. ( Salicaceae ) ( Tarasi et al. 2006), confirmed with immatures.

Biology.

Immatures induce leaf roll galls and are considered a pest ( Tarasi et al. 2006) (Fig. 1 E, F ). See also comment on biology under C. fulgidipennis .

Comment.

The records from Jordan ( Al-Khawaldeh et al. 1997; Burckhardt et al. 2024) concerns C. trjapitzini .
