Otacilia shennongjia sp. nov. (θḢXŴṚff)

Figs 37–39

Type material. Holotype ♁, CHINA: Hubei Province: Shennongjia Forestry District, Hongping Town (31°41′41.62″N, 110°25′40.44″E, 1753 m a.s.l.), 24 Oct. 2020, leg. Luyu Wang.

Paratypes: 4 ♀, with same data as holotype .

Etymology. The species name is derived from the type locality; noun in apposition.

Diagnosis. This new species resembles O. triangula Mu, Jin & Zhang, 2022 in having a similarly shaped embolus and spermathecae, but can be recognized by: 1) the absence of a scar on the embolus (vs with scar, cf. Fig. 38B, C and fig. 11B, C in Mu et al. [2022]), 2) the longer retrolateral tibial apophysis, with a slightly curved tip (vs short, not curved, cf. Fig. 38B and fig. 11B in Mu et al. [2022]), 3) the rectangular conductor (vs triangular, cf. Fig. 38C and fig. 11C in Mu et al. [2022]), and 4) the anteriorly wide, posteriorly narrow median septum (vs anteriorly narrow, posteriorly wide, cf. Fig. 38E and fig. 11E in Mu et al. [2022]).

Palp as in Figs 38A–D , 39A–C . Femoral apophysis well developed, near middle of femur. Tibia short, about half length of femur. Prolateral tibial apophysis distinct, round. Retrolateral tibial apophysis long, tip slightly curved, vertical in retrolateral view. Tegulum pyriform, retrolateral margin straight; tegular apophysis long, clavate-shaped. Sperm duct distinct, tapering from retrolateral side of tegulum to embolus, occupying about half length of tegulum. Embolus thick, strongly curved. Conductor nearly rectangular, membranous.

Other characters as in male, except carapace darker and dorsal scutum absent ( Fig. 37C, D ).

Epigyne as in Figs 38E–F , 39D–E . Epigynal plate sclerotized, slightly depressed in center. Median septum wide anteriorly, narrow posteriorly. Copulatory openings oval, separated by more than 1.5 diameter of spermathecae. Copulatory ducts short. Connecting tubes long and curved, bow-shaped. Glandular appendages short, mastoid-shaped. Bursa large, transparent, kidney-shaped. Spermathecae oval, separated by about 1/4 their diameter. Fertilization ducts located at anterior margin of spermathecae.
