Zoobank: 042D5123-63DD-4D31-B55C-38A55C95D402 ( Figures 16–20 ) Diagnosis Female and male — Idiosoma moderately to well sclerotised; the gnathotectum three-prong type with similar prongs, the central one slightly longer; opisthonotum with 24 regular setae pairs plus one pair of supplementary setae (Sx), located laterally; Tr IV with a non-distinct low tubercle dorsally. Female — The sternal shield anterior margin concaved; presternal plates with non-distinct adaxial protrusions and arcuate posterior margin; gv1 located adaxially at the st3 sternal setae level; paragynial shields with metagynial sclerites narrow and arcuate, ending anteriorly far from the anterior paragynial margin, and posteriorly in a midway of posterior paragynial lobe, axial and posterior margins of the posterior paragynial lobe join at a right angle; the anterior as in Figure 7 . Note a pair of supplementary setae ( Sx ). Figure 16 Leptogamasus ( L. ) horribilis n. sp. , opisthonotum of the female (holotype). Abbreviations margins of the epigynial shield straight, the apex separate from the rest of the epigynial by a transversal band of less pigmented cuticle, the internal (dorsal) surface of the epigynium with a pair of distinct teeth; endogynial spherules circular, stipule large and richly dentated, the walls of endogynial sac with many centripetal teeth, both on the ventral margin and the sac walls. Male — Genital lamina with anterior corners and lateral margins rounded; presternal plates quadrilateral, with distinct anterior protrusions; corniculi adaxial margin with a protrusion; cheliceral fixed digit straight, with one-two low tubercular teeth, and a lamellar arcuate protrusion in front of the pilus dentilis, followed by a row of approx. nine, somewhat irregularly distributed denticles; leg II laterally: femoral main spur moderately long, the axillary process slightly asymmetric, genual spur conical and rounded apically, whereas the tibial one rather elliptic, the genual spur located closer to the distal article margin than the tibial spur.
