Etymology. The specific name is from the Latin “ conicus ”, and refers to the large conical ATA on the bulb of male palp.

Diagnosis. The new species is very similar to another new species: Lysiteles dentatus sp. nov. in the body shape and spots on dorsum, but differs in: prosoma lacking stripe (with a pair of grayish brown stripes in L. dentatus ); copulatory ducts short, forming single coil (long and twisted, forming two coils in L. dentatus ); bulb flat with a large conical ATA (with a small, denticle-shaped ATA in L. dentatus ); embolus stout (long and helical in L. dentatus ); RTA shorter than in L. dentatus .

Description. Male (holotype): Total length 3.10, Prosoma 1.50 long, 1.30 wide; opisthosoma 1.70 long, 1.20 wide. Carapace yellow with several long bent setae.

Opisthosoma narrower than in male, anteriorly with scattered small black spots, each with a long black hair; posteriorly with 3 pairs of black bands, with a pair of small black stripes on the rear bilaterally and black lines on the side. Venter light yellow, with a rectangular large gray stripe with 2 pairs of small white spots anterior of spinnerets.

Epigyne-vulva ( Figs. 10–12 , 24–25 ). Epigyne brown, sclerotized plate slightly concave medially. Copulatory openings lateral; copulatory ducts curved, arc-shaped; spermathecae large, globular.

Variation. Total length: female 2.70–3.40 (n = 15), male 2.60–3.20 (n = 23). Carapace pale yellow to yellow. The spots on dorsum vary in size and color, from gray to black; dorsal bands fused in some females.

Distribution. China (Yunnan Province).
