The specific epithet is an English noun in apposition, referring to the stunning color of Erhai Lake near the type locality. On sunny days, the blue sky is mirrored in Erhai Lake, evoking this enchanting dark blue color. Diagnosis. The new species is similar to H. tengchongensis (Lei & Peng, 2013) in the short copulatory ducts, oval spermathecae and slender vRTA, but can be distinguished by the absence of transverse light-colored bands on the dorsal opisthosoma (Figs 31–32; vs. present in H. tengchongensis, see Lei & Peng 2013: 106, figs 7a–b); the longer embolus (Figs 38, 43; vs. shorter and beak-like in H. tengchongensis, see Lei & Peng, 2013: 107, fig. 8a); PL rounded (Figs 38, 43; vs. almost triangular in H. tengchongensis, see Lei & Peng 2013: 107, fig. 8a); the absence of the concave epigynal structure in the epigyne (Figs 41, 45; vs. obvious in H. tengchongensis, see Lei & Peng 2013: 107, fig. 8d); CO in the vicinity of genital groove (Figs 41–42, 45–46; vs. far away from genital groove in H. tengchongensis, see Lei & Peng 2013: 107, fig. 8d).
