Two new genera of Cantharidae from Burmese amber of the Hukawng Valley (Insecta, Coleoptera)

In the present paper two new genera and three new species of fossil Cantharidae from Burmese amber are described and figured: Burmomiles gen. nov., Sanaungulus gen. nov., and Burmomiles willerslevorum sp. nov., Sanaungulus curtipennis sp. nov., Sanaungulus ghitaenoerbyae sp. nov. The new genera present characteristic features as pectinate antennae with only three, four, or seven central antennomeres with long antennal processes (in the antennomeres IV-VI or IV-VII in Sanaungulus and in the antennomeres III-IX in Burmomiles), unknown until now in the fossil record. Sanaungulus gen. nov. differs from Burmomiles gen. nov. by possessing shorter elytra, smaller size, longer legs, and different pronotal shape. The new genera described herein, which are assumed to have vesicles for chemical defense, further differs from the similar genus Ornatomalthinus Poinar et Fanti, 2016 by possessing different elytral sculpture and pectinate antennae instead of filiform.
