Apertochrysa ‘Ap2’ (temporary name)

‘greenhead’ partim (Duelli and Obrist, 2020)

‘pp2’ (Duelli and Henry, 2021)

Diagnosis: Available live-colored material: 86♀, 80♂ ( Switzerland, Italy, France, Germany, Liechtenstein)

Medium-sized lacewing with bluish-green or grass-green color ( Fig. 14 ). Palps with dark rings and dark brown tips. Face whitish, vertex green, yellowish-green or sometimes yellow. Subantennal sutures always red or brown in live or freshly dried material. Black interantennal spot roundish, often pear-shaped, rarely bell-shaped. Scape and vertex never with dark marks. Female forewings 12.0–15.0 mm, male forewings 9.5–13.5 mm. Costal crossveins typically around 50% dark, but in some populations up to 100% dark. Males with furwings, and the proximal ccv is often distorted. Veins around im cell 10–40% dark, usually in one piece. The gradate crossveins are different in males and females; males usually have pale gradate crossveins, whereas in females they are darker than the longitudinal veins. Spots on the prothorax are reddish, brown, or black, usually in one pair, but sometimes also in two pairs on a brown longitudinal band. The three lateral prothoracic spots are brown or black. On the abdominal tergites, there are one or rarely two pairs of spots on most segments. The spots are normally brown or black, rarely reddish-brown. Most segments have brown or black lateral marks on the abdomen. The ventral side of the abdomen is usually whitish in females and green in males, with pale or dark setae, or mixed. The green eggs are deposited singly. The larvae diapause as third instars.

Distribution: Thus far known from Europe and western and central Asia
