Paratypes: 1 female with same data as for holotype ( CAS, CASENT 9020489 ) . 1 female with same data as for holotype, except: N26.12374°, E26.86070° to 50 m S of N26.13198°, E98.86149°, 910–990 m, D. H. Kavanaugh & P. Paquin leg., field number DHK-2005-056 ( SMF, CASENT 9023088 ) .

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

Diagnosis: Females of S. wayala spec. nov. can be distinguished from other Sinopoda species by the following combination of characters: 1. small ALE and PLE, 2. lobal septum covering nearly whole epigyne and with median indentation anteriorly, 3. epigynal pockets extending only in anterior part of epigyne, 4. glandular appendages curved and extending only in anterior half of internal duct system, 5. posterior part of spermathecae bulging lateroventrally, spherical and distinctly wider than anterior part and 6. fertilization ducts situated postero-medially.

Cheliceral furrow with 3 anterior and 4 posterior teeth.

Colouration in ethanol: Prosoma yellowish-brown, medially with brown stripes, anterior part red, posterior and lateral margin brown. Sternum yellow with brown margin. Opisthosoma ventrally and dorsally greyish-yellow, dorso-medially with four brown spots. Chelicerae reddish-brown. Palps yellowish-brown; Mt reddish-brown. Legs yellowish-brown; Mt and Ta light reddish-brown.

Copulatory organ as in diagnosis. Epigynal field wider than long with two long anterior bands, right band discontinuous, and two slit sensilla. Lateral lobes fused, posterior part with shallow median indentation. Epigynal pockets running from medio-lateral to medio-anterior. Fusion bubbles situated posteriorly and medially on epigyne. Internal duct system wider than long. Spermathecae fused anteriorly and medially along median line with distinct seam. Glandular appendages with conspicuous glands.
