Abstract
Two new Diaphanes Motschulsky 1853 species, D. meghalayanus Nonglang, Das, Shangpliang sp. nov., and D. mawlynnong Nonglang, Das, Shangpliang sp. nov., from Meghalaya, Northeast India, are described. Diaphanes meghalayanus sp. nov., is characterised by a unique colour pattern of the central disc, the absence of a typical circular pronotal areolet area, brownish-yellow pronotum and elytra, and other specific features of male genitalia. Diaphanes mawlynnong sp. nov., is distinct with rare moniliform antennae, circular-shaped pronotal areolet areas with blunt posterior lateral corners, and specific genital aedeagus characters. The female of D. mawlynnong sp. nov., which is apterous, was found in the same habitat where its males were associated. 13 Diaphanes species have been recorded from India, and with the discovery of these two new species, the number of Diaphanes species recorded in the country increases to 15. This knowledge significantly contributes to the existing information gap of Diaphanes diversity and distribution in this region.
