Psomizopelma albiclava n. sp.

- Clava entirely dark ( Figs 17 , 36 , 59 ); fore wing extending only to about base of gaster ( Figs 24 , 38 , 54 ); head, mesosoma and metasoma mostly dark brown ( Figs 17 , 32 ) or dark with metallic lusters ( Fig. 54 ); head with parascrobal region between toru- lus and inner orbit at least about half as wide as intertorular distance ( Figs 20 , 35 , 57 )............................... 4 4(3) Gaster with only Gt1 and Gt2 white laterally ( Fig. 33 ); head virtually entirely dark brown with clypeus only inconspicuously paler ( Fig. 35 ); ovipositor sheaths brown ( Fig. 33 )...................................... Psomizopelma fuscum n. sp.

5(4) Head and mesosoma dorsally and sometimes gaster dorsally with distinct metallic green to blue or purple lusters ( Figs 54–56, 61, 62 ); acropleuron meshlike coriaceous over at least posterior half ( Fig. 58 )............. Psomizopelma metallicum n. sp.

6(1) Body essentially uniformly brown ( Figs 25, 26 ) except often for white basal two pro- and/or mesotarsomeres ( Fig. 26 ); flagellum robust-filiform with at least more apical funiculars quadrate ( Fig. 28 ); propodeum bare mesal to spiracles ( Fig. 31 )............................................................................ Psomizopelma brachypterum Gibson

- Body with following pale: scape extensively ( Figs 11, 12 ), pronotum at least laterally ( Figs 13, 14 ), variably distinct spot on mesoscutal lateral lobe ( Fig. 13 ), pro- and mesotibiae, and dorsal margin of metatibia ( Figs 9, 10 ); flagellum more gracile-filiform with all funiculars obviously longer than wide ( Fig. 12 ); propodeum on either side of median carina with 2 setae about midway between spiracle and foramen ( Fig. 16 ).....................................
