Diagnosis

Creatapsyche kachini sp. nov. can be distinguished from all other species in the genus by having Rs branching before M in the forewing. In all other species, Rs and M branch at about the same level, or M branches before Rs. Additionally, in the male genitalia the harpago is two-thirds the length of the coxopodite.

Etymology

Cretapsyche kachini sp. nov. is named after Kachin State in Myanmar, where the amber inclusion was found.

Material examined

Holotype MYANMAR – Kachin State • ♂; exact locality unknown; Mid-Cretaceous Burmese amber inclusion; deposited in the amber collection of the ZFMK; former Patrick Müller Collection, BUB 540; ZFMK-TRI000829 .

Body well preserved; forewing in dorsal view, hindwing covered dorsally by forewing. Antennae and legs present. Male genitalia visible in ventral view.

Description

Male

Ocelli absent. Antennae probably about as long as forewings (holotype antennae incomplete). Scapus about as long as head. Maxillary palps 5-segmented, 2 nd segment longest, following segments decreasing in length, 3 rd segment basally barrel-shaped and extended laterad to form pointed spur corresponding in length to 4 th and 5 th segments. Body and wings light brown. Forewing with length 2.8 mm longer than small hindwing. In forewings, apical forks II, III and V present, discoidal cell absent, thyridial cell present, Cu2 running continuously to Cu1b. In hindwings, apical forks I, III and V present (difficult to see, holotype forewing hides hindwings in dorsal view). Tibial spur formula 2/2/4. In male genitalia, two-segmented inferior appendages characterized by basally broad coxopodite, tapering and curving mesad. Harpago elongate and tapering continuously towards apex, two-thirds of coxopodite length.
