The specific name refers to the type locality, Longtan; adjective.

Differential diagnosis.

The female of this species is similar to that of O. fujiana Fu, Jin & Zhang, 2014 but differs by the chelicerae having two retromarginal teeth (Fig. 12B ) (vs. five retromarginal teeth) and the oval spermathecae (vs. with clavate shafts). Male unknown.

Description.

Female. Habitus as in Fig. 12A, B . Total length 4.81, carapace 1.69 long, 1.01 wide. Eye sizes and interdistances: AME 0.11, ALE 0.11, PME 0.09, PLE 0.10; ALE-AME 0.04, AME-AME 0.08, PLE-PME 0.08, PME-PME 0.13, ALE-ALE 0.34, PLE-PLE 0.45, ALE-PLE 0.13, AME-PME 0.11, ALE-PME 0.18. MOA 0.32 long, front width 0.30, back width 0.32. Chelicerae (Fig. 12A ) with three promarginal (middle largest, distal smallest) and two retromarginal teeth (distal larger). Sternum (Fig. 12B ), with distinct precoxal triangles, posterior pointed. Abdomen (Fig. 12A ) 2.70 long, 1.66 wide. Leg measurements: I 9.66 (2.41, 0.71, 3.17, 1.89, 1.48); II 7.91 (1.99, 0.62, 2.32, 1.68, 1.30); III 6.20 (1.50, 0.58, 1.56, 1.57, 0.99); IV 9.81 (2.45, 0.69, 2.51, 2.71, 1.45). Leg spination: femora I-IV with one dorsal spine each; femora I pv111111, II pv111; tibiae I v2222222222, II v22222222; metatarsi I v2222, II v1222.

Colouration (Fig. 12A, B ). Carapace yellow to yellow-brown, with radial, irregular dark stripes mediolaterally and arch-shaped dark stripes around margin. Chelicerae yellow. Endites yellow. Labium yellow-brown. Sternum yellow, with yellow-brown margin. Legs yellow, without annulations on tibiae and distal part of femora, patellae and metatarsi (Fig. 12A, B ). Abdomen dark brown, with abundant yellowish spots in dorsal view.

Epigyne (Fig. 12C, D ). Epigynal plate trapezoid, antero-medially with pair of slit-like copulatory openings, with a narrowed median septum, copulatory ducts, glandular appendage, connecting tubes and spermathecae distinctly visible through integument in intact epigyne. Copulatory ducts very short, relative broad, between copulatory openings and glandular appendage, with pair of elongated transparent bursae anteriorly. Glandular appendages short, proper thick, located on the anterior of connecting tubes. Connecting tubes short, as long as copulatory duct, broad, located between glandular appendages and spermathecae. Spermathecae elongated, oval, slightly separated at their apex. Fertilisation duct short, located apically on spermathecae.
