The genus is named Latin gracilentus "slender" (according to the authors "simple") for the simple paracymbium in the male palp.^[1]

G. denticulatus is named after the radix with teeth in the male palp. G. serratus is from Latin serratus "saw-edged", for the saw-shaped posterior margin of the ventral plate in the epigyne. G. tengchongensis is named after the type locality, Tengchong County (腾冲; Téngchōng) in Yunnan Province.^[1]

G. mangshanensis is named after its type locality, Mangshan (莽山; Mǎng shān) in Hunan Province.^[3]
