Plazi
Diagnosis . Females are easily distinguished from known congeners by pair of deep cavities on anterior epigynal plate ( Figs 30 , 33 ); males differ from known congeners by combination of distinct stridulatory ridges laterally on chelicerae ( Fig. 20 ); bulbal process c present, rounded ( Fig. 8 ); and procursus distally with one light notch in dorsal view ( Fig. 7 ).

Plazi
Description. Male ( holotype ). MEASUREMENTS. Total length 5.3, carapace width 2.4. Distance PME-PME 150 µm; diameter PME 130 µm; distance PME-ALE 90 µm; distance AME-AME 50 µm, diameter AME 140 µm. Leg 1: 32.7 (8.4 + 1.2 + 9.3 + 11.9 + 1.9), tibia 2: 6.8, tibia 3: 5.2, tibia 4: 7.5; tibia 1 L/d: 34. COLOR (in ethanol). Carapace pale ochre-yellow with dark brown median band and light brown ocular area; clypeus with brown median band and brown rim; sternum pale ochre-yellow; legs ochre-yellow, with brown rings in patella area, on tibiae subdistally and on metatarsi proximally; femora 1 proximally red-brown. Abdomen pale gray, dorsally with large dark marks extending towards lateral sides; ventrally with brown area in front of gonopore. BODY. Habitus as in Fig. 1 . Ocular area slightly elevated, deep thoracic pit behind ocular area, thoracic furrow in posterior part of carapace; clypeus unmodified except for brown rim. Sternum wider than long (1.55/1.25), unmodified. Gonopore with four epiandrous spigots. CHELICERAE. As in Figs 19–20 , with several sclerotized cone-shaped hairs in distinctive arrangement, with distinct stridulatory ridges. PALPS. In general very similar to known congeners (cf. Figs 28–29 ); coxa unmodified, trochanter ventrally slightly projecting and strongly sclerotized, femur strongly widened, with retrolateral apophysis proximally pointing towards ventral, with stridulatory pick (modified hair) prolaterally near joint to trochanter, patella very short, ventrally closed, i.e. not reduced; tibia retrolateral trichobothrium in very proximal position; procursus with distinct dorsal apophysis and ventral pocket in very proximal position, distally widened, with one light notch in dorsal view ( Fig. 7 ); genital bulb with short membranous embolus accompanied by two processes (processes a and b in Aharon et al. 2017 ), with distinct process c and very small process d ( Figs 8 , 13–14 ). LEGS. Without spines and curved hairs, few vertical hairs; regular mechanoreceptive hairs either thick and very long (on all leg segments except on tarsi; length ~0.75–2.1) or thin and short (very dense on all leg segments; length ~0.08–0.15); retrolateral trichobothrium of tibia 1 at 6%; prolateral trichobothrium present on all tibiae; tarsus 1 with ~15 pseudosegments, very indistinct. Male (variation). The other three males examined are larger in all respects but genitalia and chelicerae appear largely identical and the male from near Fasah is accompanied by two females that share the highly distinctive epigynum of the female from the type locality; the males are thus all considered conspecific. Tibia 1 in two other males (missing in third male that is severely damaged): 12.9, 13.2; palpal femur length in holotype : 1.50, in other males: 1.80, 1.85, 2.20. Males from near Miskin and from near Fasah with slightly larger bulbal process c, and clearly larger bulbal process d. Female . In general similar to male ( Fig. 2 ), also with stridulatory ridges on chelicerae, but clypeus rim not brown and femora 1 proximally ochre-yellow (not red-brown). Tibia 1 in 5 females : 6.5–12.3 (mean 10.3) ( type locality: 6.5). Epigynum anterior plate wider than long, trapezoidal to rectangular, with pair of distinctive deep cavities anteriorly laterally ( Figs 30 , 33 ); pair of large, slightly bulging light brown projections in front of anterior epigynal plate; posterior plate wide and short. Internal genitalia simple, with pair of distinctively shaped pore plates ( Figs 25 , 34 ).
Counts are recordings at or below each taxon, so an empty branch shows as empty before you click it. A dash means the join view holds no column for that rank and cannot roll up to it.
The rows audioBlast holds for this taxon, each matched to the same Catalogue of Life node. Where a source classifies it differently, its own classification is kept.
