Paraxya hui sp. nov. (Figs. 3–5)

Holotype: Adult male, Hukang Valley , Kachin State, Northern Myanmar, Mid Cretaceous, about 100 million years, leg. Zheng-Kun Hu, 2018-11-23.

Male Body 2.90 mm long measured from the head to the abdominal apex; the specimen in Cretaceous amber (fig. 3).

Head Vertex somewhat inflated anteriorly; frons broadly curved. Antennae filiform, with ten articles, length of apical segment 3.0 times width. Eyes very large and circular. (figs. 4a, 5a).

Thorax Pronotum large, shield-like, extending posteriorly to entirely cover the mesonotum. Tegmina strongly sclerotized. Hindwing long, surpassing over the end of abdomen distinctly (figs 4b, 5b). Profemur robust, apical part narrower, with a strongly concave ventral surface and very long external ventral setae; protibia broad, strongly inflated distally with a dense covering of strong setae; basitarsus short, basal half part wider; apical tarsomere elongate, slightly curved distally; pretarsus with two prominent ungues. Mesofemur markedly longer and wider than the profemur. mesotibia similar in shape to the protibia but more pointed apically; mesotarsus almost identical to the protarsus, very long, about twice as long as the protarsus. Metathoracic leg saltatorial; metafemur very large, as long as the abdomen and greatly inflated along its entire length, with prominent dorsal carina; external genicular lobe prominent, smooth; metatibia almost as long as metafemur, very slender, subquadrate in section, without swimming plates and spines on the dorsal margins, with a pale ring at base; metatarsus invisible; apical spurs long, about twice as long as the subapical spurs (Figs 4c, 5c).

Abdomen Terga and sterna covered by hind leg, invisible, cercus with 4 particularly long hairs.

Etymology: The new species is derived from Mr. Zheng-Kun Hu for his type specimen.
