SICARIUS WALCKENAER, 1847 View in CoL

Sicarius Walckenaer, 1847 View in CoL . Type species by monotypy Sicarius thomisoides Walckenaer, 1847 View in CoL , designated by F.O. Pickard-Cambridge (1899a) (against Simon , 1893, who considered S. terrosus Nicolet, 1849 View in CoL to be the type species of Sicarius View in CoL ).

Thomisoides Nicolet, 1849 View in CoL . Type species T. terrosus Nicolet, 1849 View in CoL , designated by Simon (1893). Synonymized by Simon (1893).

Sicarioides F.O. Pickard-Cambridge, 1899 . Type species by original designation S. rugosus F.O. Pickard-Cambridge, 1899 View in CoL . Synonymized by Simon (1903).

Diagnosis: Males can be distinguished from those of Hexophthalma gen. reval. by the subconical body of the bulb ( Fig. 32 View Figure 32 , Magalh aes ~ et al., 2013: fig. 28) (long and with parallel sides in Hexophthalma , Fig. 20A, C View Figure 20 ). Females can be distinguished by the presence of a dense tuft of setae just anterior to the spinnerets ( Fig. 9A, D View Figure 9 ; Magalh aes ~ et al., 2013: fig. 31, ht) (absent in Hexophthalma ). Both males and females can also be distinguished by having posterior median spinnerets ( Figs 5A View Figure 5 , 9F View Figure 9 , 10A, C View Figure 10 ) (PMS absent in Hexophthalma ; Figs 6A, B View Figure 6 , 11A View Figure 11 , 12C View Figure 12 ) and by having dense patches of long black setae that partially hide the ALS spinning fields ( Fig. 9A View Figure 9 , bs; Magalh aes ~ et al., 2013: fig. 32, bs) (setae much shorter, not hiding the ALS spinning field in Hexophthalma ; Fig. 12C View Figure 12 ).

Description: As for the subfamily, except for the following. Cephalic region 0.3 – 0.5 times as wide as carapace length. Chelicerae lamina with strongly sclerotized apex ( Fig. 13A View Figure 13 ). Sternum usually cordiform, wider than long and posteriorly truncate; oval in S. thomisoides and S. yurensis stat. nov. ( Fig. 30 View Figure 30 ). Palp with simple or sculptured femoral thorns. Leg femora with or without prolateral black setae, generally with brown macrosetae, rarely with white and brown macrosetae ( Fig. 24 View Figure 24 ). Abdomen with a dense tuft of setae anteriorly to the spinnerets in adult females ( Fig. 9A View Figure 9 ). ALS covered by long, black setae partially covering the spinning field, with long and filiform major ampullate gland spigots (one, two or absent) ( Figs 9E View Figure 9 , 10B View Figure 10 ). PMS present, with a few aciniform gland spigots ( Figs 9F View Figure 9 , 10C View Figure 10 ). Inner spermathecae branched, with branches inserted throughout the bursa ( Figs 19A, B View Figure 19 , 33). Outer spermathecae absent ( Figs 19A, B View Figure 19 , 33).
