Diagnosis
Females of S.lucida resemble those of S.excavata sp. nov. and S.marmorata sp. nov. by their short and rounded opisthosomal projections (Figs 2F, 12A). They can be distinguished by shorter copulatory ducts and spermathecae with just a median twisted constriction instead of many chambers (Fig. 12D, F). Males are similar to those of S.excavata sp. nov. by the colour pattern of the opisthosoma and the shape of its posterior projections. However, males of S.lucida have a roundish RTA with a discrete basal branch (Fig. 13D, F), narrower pars pendula, and a shorter embolus emerging from tegulum at five o’clock (Fig. 13C, E).
Description
Female: Prosoma yellowish, with cephalic ridges delimited by lines of small papules; needle-shaped setae concentrated on the median area of prosoma, being the largest ones disposed right back of the PLE (Fig. 12B). Legs yellowish, with femora I bearing three equal-sized needle-shaped macrosetae on their mesial surface (Fig. 12A); both the anterior tibiae and metatarsi (I and II) ventrally armed with five pairs of ventral macrosetae; tibiae I also bear a pair of smaller macrosetae along their mesial surface (Fig. 12A). Opisthosoma light-yellow with a median black stain on its anterior portion; posterior projections stout, obtuse and vertically oriented (Fig. 12A). Epigynal plate wide, depressed on the median field; posterior folds thick and converging in the middle to form a septum (Fig. 12C, E).

Male: Prosoma and legs as in female; opisthosoma predominantly yellow with lateral whitish lines, posterior projections dark (Fig. 13A, B). Palp flattened dorsoventrally and elongated; cymbium distally narrowed; tegulum rounded with scaled surface (Fig. 13C–F). Measurements: eyes diameters and eyes interdistances: AME 0.05, ALE 0.07, PME 0.05, PLE 0.05, AME–AME 0.11, AME–ALE 0.05, PME–PME 0.09, PME–PLE 0.17, MOQ length 0.29, MOQ width 0.23; leg formula: 1–2–4–3: leg I – femur 2.56/ patella 0.88/ tibiae 2.48/ metatarsus 2.12/ tarsus 0.72/ total 8.76; II – 1.68/ 0.60/ 1.36/ 1.28/ 0.56/ 5.48; III – 0.64/ 0.32/ 0.56/ 0.28/ 0.36/ 2.16; IV – 0.84/ 0.44/ 0.48/ 0.24/ 0.36/ 2.36.
