Diagnosis.

Females of C. baoting sp. n. can be distinguished from those of other Conothele species by the spermathecae with plate-shaped lobes, each stalk slender, long, distally sclerotized and thickened, and narrowest in the middle. It can be distinguished from C. baisha sp. n. by long stalks each with an obvious trench between the distal part of the stalk and the lobe (Fig. 7G). Moreover, C. baoting sp. n. can be diagnosed from C. baisha sp. n. by the following unique nucleotide substitutions in the standard DNA barcode alignment: G (13), T (97), G (134), A (157), G (172), A (196), T (205), G (223), C (224), T (253), A (280), T (302), A (304), T (322), C (376), G (421), A (424), G (502), A (520), G (592), G (634), A (637).

There is an obvious trench between the distal part of the stalk and lobe (Fig. 7G).

Variation.

The female genitalia show considerable intraspecific variations: the stalks of some specimens are unbent (Fig. 8A, D, E, G, H, I, K, L), while others are slightly curved (Fig. 8B, C, F, J, M, N); there are three different shapes of lobes of spermathecae, slightly globular (Fig. 8D, E, G, J, K, M, N), bowl-shaped (Fig. 8A, B, F, H, I, L), and plate-shaped (Figs 7G, 8C).

Male.

Unknown.
