diagnosis
Diagnosis: Females of S. mat spec. nov. are similar to those of S. tham in having elevations medially on bent posterior part of spermathecae and to those of S. semicirculata in having elevations medially on bent posterior part of spermathecae and the lateral endings of the epigynal pockets extending anteriorly beyond visible part of lobal septum. They can be distinguished from S. tham by 1. lobal septum with median part wider than anterior part (median part narrower than anterior part in S. tham), 2. epigynal pockets running from latero-anterior to medio-posterior (from latero-posterior to medio-anterior in S. tham), 3. posterior part of lateral lobes completely fused (with median indentation in S. tham), 4. glandular appendages wide (narrow in S. tham), 5. elevations wider than long (nearly as long as wide in S. tham) and 6. fertilization ducts wide (slender in S. tham); from S. semicirculata by 1. reduced eyes (not reduced in S. semicirculata), 2. spermathecae completely fused along median line and posterior part bent laterally at right angle (only partly fused along median line and posterior part bent latero-ventrally in S. semicirculata) and 3. elevations spherical (not spherical in S. semicirculata).
distribution
Distribution: Known only from the type locality.
etymology
Etymology: The species name is derived from the Vietnamese word “ m ắt ” meaning “ eye ” and refers to the fact that all eight eyes are developed but reduced in size; noun in apposition.
