Type species

Cretapsyche Wichard, Neumann, Müller & Wang, 2018 .

Revised description

HEAD. Male adult embedded in amber, light brown coloration. Large complex eyes on sides of head, slightly longer in diameter than head length. Ocelli absent. Antennae as long as, or slightly longer than forewings, each with scapus about as long as head, often bearing brush of dark setae; flagellomeres uniformly bar-shaped. Maxillary palps five-segmented; second segment longest, following three segments successively smaller and shorter; fifth segment shortest ( Figs 2–4 ).

THORAX. Pronotum with one pair of oval setal warts. Mesonotum without setal warts on mesoscutum.

MESOSCUTELLUM. With one domed setal wart or pair of domed setal warts fused medially.

TIBIAL SPURS. 2/2/4.

WINGS ( Fig. 1 ). Forewings broader than hindwings, each with rounded apex. In forewings, forks II, III, and V present; cubitus vein Cu2 ending in Cu1b or connected to Cu1b by crossvein. Discoidal, median, and thyridial cells present or absent. Nygmata absent. Anal vein reaching wing margin before fork V or before crossvein reaching wing margin. Hindwings with forks I, III, and V present.

MALE GENITALIA. Inferior appendages two-segmented, consisting of basal coxopodite and harpago simply attached to apex of coxopodite. Coxopodite arcuate, sub-triangular or scaly, broad, long and curved; harpago finger- or needle-shaped, often straight at base and curved mesad at apex. Two parallel appendages located centrally in genitalia interpreted as probable mesodorsal pair of lobes of tergum X. Preanal appendages small, elongate or finger-like curved.
