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. Fig. 3. Cretapsyche kachini sp. nov. , holotype, ♂ (ZFMK-TRI000829). A . Dorsal view. B . Drawing of a forewing. C . Maxillary and labial palps. D . Drawing of the maxillary palp. E . Male genitalia in ventrolateral view, distinctly flattened and partially distorted. F . Drawing of male genitalia, left half. 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.
