Eucryptorrhynchus khasiensis Devi, Dey & Ray, 2016

( Figs. 1E, F , 2E, F )

Material examined. CHINA, Yunnan: 1 male (ex. 1; accession number: PP697491) ( TARI), Bangda [fflṁ], Mang City, coll. Y-T Wang, 8 September 2015 .

Distribution. India (Khasi hills) ( Devi et al., 2016). New record: China (Yunnan).

Identification key. We provided a revised identification key that covers five of the six described Eucryptorrhynchus species. For the morphological comparisons of two species, E. papuanus and E. cenninii , we had to rely on the original descriptions due to the unavailability of specimens for examination. Additionally, we were unable to include E. intermedius in the key, due to the unavailability of specimens for examination and the limited information available in the original description of this species.
