Water rice weevil, Quang Ninh, Vietnam

March 2017. A request for the identification of this water rice weevil with attached photos of the adult, collected in Quang Ninh province of Vietnam (border with China). It is Echinocnemus squameus or Lissophoptrus oryzophilus?

A member wrote: It’s Echinocnemus, probably E. squameusbut this cannot be determined with certainty from photos alone. In the photos of the legs you can see the row of spines on the inside of the tibiae, for which the genus was named, echinusmeaning spine and cnemismeaning shin. Lissorhoptrusdoesn’t have such spiny tibiae.
