Diagnosis

Males and females differ from Kochiana brunnipes by the color pattern, black with red setae in dorsal abdomen, maxilla, and chelicerae basal segment dark grey bordered by red setae ( Figs 19–24 , 117–118 ). Males of K fukushimae sp. nov differ from those of K. brunnipes by the shorter embolus, less curved in ventral direction ( Figs 79–81 ), the subtle accessory keels (AC) ( Fig. 80 ) and the retrolateral branch of tibial apophysis less flattened ( Fig. 87 ). Females differ from K. brunnipes by the spermathecae not projected in ventral direction and by absence of middle depression (MD) at base ( Fig. 89 ).

Etymology

The name is given in honor of Dr Caroline Sayuri Fukushima, for her valuable contribution to Theraphosidae taxonomy and conservation.
