Diagnosis

Cretapsyche myanmari sp. nov. can be distinguished from all other species in the genus by having M branching before Rs in the forewing and an open thyridial cell. Cretapsyche myanmari sp. nov. can also be distinguished in the male genitalia by the mesodorsal processes of tergum X, scale-shaped, each with two black spines.

Etymology

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

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 3597; ZFMK-TRI000830 .

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 little longer than forewings. Scapus about as long as head, smaller pedicellus, followed by more than 30 cylindrical flagellomeres gradually shortening in length apically. Maxillary palps 5-segmented, 2 nd segment longest, following three segments successively smaller and shorter. Body and wings light brown. Forewing with length about 2.8 mm. In forewings, apical forks II, III and V present, discoidal and thyridial cells absent, Cu2 running continuously to Cu1b. In hindwings, apical forks I, III and V present (holotype hindwings partially spread laterally and visible). Tibial spur formula 2/2/4. In male genitalia, two-segmented inferior appendages characterized by finger-shaped, curved coxopodite and by short and cone-shaped harpago. Two appendages, each with two dark spines, located centrally in genitalia interpreted as probable mesodorsal pair of lobes of tergum X ( Wichard 2021).
