Females of T. flava sp. nov. are most similar with the females of T. striata , but can be distinguished from the latter by the following combination of characters: Female opisthosoma oval with caudal tubercle and without shoulder humps (opisthosoma of female T. striata triangular with paired shoulder humps and without caudal tubercle), copulatory ducts with median twist less evident and less number of wrinkles (copulatory ducts of T. striata with sharp median twist and numerous wrinkles) and nearly uniformly enlarged spermathecal bulb ( T. striata with narrow spermathecal bulb) (compare Figs 3D–F , 4E–H with Figs 13D–F , 14E–F , Yin et al. 2012 : fig. 216b–c). Females of T. flava sp. nov. can be separated from the females of T. ventralis , the common representative of the genus with high intraspecific variations by the following combination of characters: copulatory ducts large, equally wide along the entire length ( T. ventralis with short copulatory ducts with narrow distal half) and enlarged spermathecal bulb (spermathecal bulb compact in T. ventralis ) (compare Fig. 4H with Fig. 18C, F, I, L, O ; Song et al. 1999 : fig. 129D; Yin et al. 1999: fig. 216c; Zhu et al. 2003 : fig. 172G; Jäger & Praxaysombath 2009 : fig. 25). Description. Female ( holotype , Figs 1A , 3D–F , 4B, D ). Prosoma uniformly yellowish without markings or patches ( Fig. 3D ). Ocular area yellowish with anterior half of median ocular quadrangle black; lateral eyes nearly contiguous, situated on a shallow tubercle. Fovea deep. Clypeus black. Chelicerae, sternum yellowish. Sternum suffused with a broad median inconspicuous black patch; distal half bears long black hairs. Fangs, labium, maxillae yellowish-brown. Cheliceral promargin with three teeth, retromargin with four teeth ( Fig. 4D ). Opisthosoma oval, greyish with a prominent caudal tubercle ( Fig. 3F ); dorsum and laterals provided with closely packed golden yellow spots of irregular size and shapes; dorsum posteriorly with a pair of black spots, one on each side of the caudal tubercle; venter provided with paired black patches lying just above the spinnerets, posteriorly bears a pair of black spots, one on each side of the posterior lateral spinnerets. Legs yellowish with black annulations on I, II and IV, prominent on leg I; leg III without annulations; femur III prolaterally with a single row of trichobothriae ( 7 in number); femur IV prolaterally with two rows of trichobothriae ( 22 in number). Spinnerets greyish. Palpal segments yellowish to yellowish-brown towards distally. Body length 7.13. Prosoma length 2.47, width 1.95, height 0.69. Opisthosoma length 4.66, width 3.31, height 3.28.

Epigynum ( Fig. 4E–H ): Epigynum represented by broad, flat, slightly irregular epigynal plate constricted postero-laterally to form a prominent postero-median lobe, the posterior borderline of which modified to form short lateral and a wide, median lobes ( Fig. 4E–F ). Copulatory openings baso-laterally placed, hardly visible ventrally. Copulatory ducts large, sclerotized, with a median twist, apical and basal parts lie away from each other, median part lies close to each other, basal part folded dorsally ( Fig. 4E–H ). Spermathecal bulb membranous, enlarged, slightly irregular, inflated balloon-like ( Fig. 4H ). Fertilization ducts narrow, tubular, sclerotized, originating baso-retrolaterally to spermathecal bulb, with a basal twist ( Fig. 4G–H ). Etymology. The specific epithet is an adjective and refers to the body colour of the new species. Latin flavus = yellow. Gender feminine. Species transfer, redescription and synonyms within Tylorida
