Differential diagnosis

Sathytes shennong sp. nov. shares with S. chayuensis sp. nov., S. xingdoumontis sp. nov., S. magnus, S. tangliangi and S. grandis the single basal protuberance of antennomere 11 and the conspicuously oblique mesal margin of antennomere 9. It differs from S. chayuensis sp. nov. by the much less elongate antennomere 11; from S. xingdoumontis sp. nov. by the more protuberant mesal margin of antennomere 9; and from the latter three species by the much smaller body size (2.29 mm vs 3.36 mm of S. magnus, 2.8 mm of S. tangliangi and 3 mm of S. grandis) and a similar but different form of antennomere 9.

Etymology

The new specific epithet ‘shennong’ (Ṗƨ) refers to the mythological Chinese deity, from which the name of Shennongjia Nature Reserve originates.
