Paraxya, Cao & Chen & Yin, 2019

Cao, Cheng-Quan, Chen, Shen-Zhi & Yin, Zhan, 2019, A new genus and a new species of pygmy mole cricket in Cretaceous amber from Burma (Orthoptera: Tridactylidae), Zootaxa 4559 (1), pp. 193-195 : 194

Paraxya gen. nov.

Type species: Paraxya hui sp. nov. (Figs. 3–5)

Diagnosis: The new genus is allied to Xya Latreille. 1809 ( fig.1 ), but differs from latter by metatibia without swimming plates. The new genus is also allied to Burmadactylus Heads, 2009 (lacking swimming plates at metatibia, fig. 2 ) and differs from latter by metatarsus absent and hindwing present, surpassing the end of abdomen distinctly (figs. 3–5).

Etymology: The new genus is name for the Xya Latreille. 1809 , Para - = allied, Paraxya showing a sister genus of Xya Latreille, 1809 in Latin.

Discussion. The hindwing of Burmadactylus grimaldii Heads, 2009 is absent, but it may be present, invisible, covered by tegmen, because the degradation of tegmen and hindwing generally may be in sync.
