Diagnosis. Females of S. monulfi   resemble those of S. armata   in having a trapezoid opisthosoma, being cryptic and robust in form, having legs bearing several stout projections and setiferous tubercles and by the median spire on thoracic portion of prosoma. However, they can be distinguished by their more flattened and wider prosoma, bigger dorsal projections on patellae and tibiae I and II ( Fig. 32A View Figure 32 ), and epigynal plate with wide CO, depressed atrium and median septum ( Fig. 32C View Figure 32 ). Males are diagnosed by their sclerotized embolus ( Fig. 33C View Figure 33 ) and short and laminar RTA that resembles a shape of an axe blade in retro lateral view ( Fig. 33D View Figure 33 ).

Description. Female (KS.108712): Prosoma predominantly reddish-brown with a small median spire on the cephalic portion ( Fig. 32B View Figure 32 ), covered by many whitish setae on the posterior slope and sides of cephalic area ( Fig. 32A View Figure 32 ); anterior eye row recurved and posterior straight; cephalic and ocular projections discrete ( Fig. 32B View Figure 32 ). Legs dark-yellow with brown tinges on the distal portion of femora, patellae and tibiae. These same leg segments bear acute projections with a terminal macrosetae and covered by smaller hyaline ones ( Fig. 32A View Figure 32 ). Opisthosoma trapezoid, predominantly light-yellow with brownish anterolateral spots. Epigynum with segmented spermathecae, glandular-heads with many perforations and anterior chambers reduced ( Fig. 32D View Figure 32 ).

Male (AMS KS.108716): Prosoma and legs predominantly burgundy colored ( Fig. 33A View Figure 33 ); eye arrangement as in female. Anterior metatarsi and tarsi (I and II) light-brown; whitish setae clustered on the median region of the posterior slope of prosoma and on the sides of cephalic area, occurring also on the lateral margin of the clypeus and between the ALE and AME ( Fig. 33B View Figure 33 ). Opisthosoma trapezoid and dark-yellow with lateral and posterior darker spots. Palpi short with Pcym rounded and RTAvbr truncated ( Fig. 33C,D View Figure 33 ).

Measurements: eye diameters and interdistances: AME 0.07, ALE 0.13, PME 0.08, PLE 0.06, AME–AME 0.07, AME–ALE 0.05, PME–PME 0.16, PME–PLE 0.05, MOQ length 0.23, width 0.25; leg formula: 1-2-4-3: leg I—femur 1.45/ patella 0.81/ tibia 1.08/ metatarsus 0.81/ tarsus 0.41/ total 4.56; II—1.43/ 0.73/ 1.00/ 0.77/ 0.43/ 4.36; III—0.99/ 0.52/ 0.73/ 0.65/ 0.42/ 3.31; IV—1.04/ 0.68/ 0.67/ 0.62/ 0.35/ 3.36. Total body length 3.59; prosoma length 1.89, width 1.92; opisthosoma length 1.70; clypeus height 0.22; sternum length 0.83, width 0.76; gnathocoxae length 0.34, width 0.19; labium length 0.20, width 0.37.

Distribution. Papua, Indonesia; Morobe, Papua New Guinea; Queensland and New South Wales, Australia ( Fig. 35 View Figure 35 ).
