Diagnosis

The male of K. pentacantha   resembles that of K. quadrata   sp. nov. by the shape of the tegulum and embolus ( Fig. 11C, E View Fig ); however, it can be distinguished by its stout and conical RTA ( Figs 11D, F View Fig , 19A View Fig ) and larger body size, since they are the largest males of genus, being the sexual size dimorphism in this species less pronounced. Females can be recognized by the external genitalia bearing a noticeable median septum and a pair of long longitudinal depressions leading to the copulatory openings ( Figs 10C, E View Fig , 22A View Fig ). The most common body color pattern for both males and females usually present a diagnostic median white spot on the dorsum of the opisthosoma ( Figs 10A View Fig , 11A).
