3.1.1.1. Genus † Cretolyra gen. nov.

Type species.

† Cretolyra noijebumensis sp. nov.

Etymology.

Combination of Creto - referring to the Cretaceous age of the Burmese amber deposit and the suffix - lyra often used in megalyrid genus names. Gender feminine.

Diagnosis.

Compound eye oval, higher than long; frons longitudinally divided by sulcus anterior to median ocellus; flagellomere 1 shorter than individual length of flagellomeres 2-5; occipital carina crenulate. Fore wing with M+Cu, Sc+R, A, M and Cu fully pigmented; cu-a almost branching with A, absent for short distance; medial cell rectangular; marginal cell narrow, closed in straight line (Figs 2A, B , 3C and 4A ). Median mesoscutal sulcus smooth; parapsidal lines present, diverging anteriorly (Figs 3B and 4A ). Metacoxa long; metafemur and metatibia swollen; two mesotibial and one metatibial spurs; row of comb-like setae along ventral surface of metatibia and metabasitarsus. Metasoma elongate and narrowed at apex, longer than mesosoma.
