Stephanopis salobrensis – Mello-Leitão 1929: 57, figs 137–139 (misidentification, only female paralectotypes).

Note

The type series of S. salobrensis is constituted by four syntype individuals of two different species. As the male has remarkable genitalic features and clear diagnostic somatic characters ( Fig. 26A–B View Fig ), we designate it as lectotype (see the section Additional taxonomic acts). The rest of the specimens in the type series are a juvenile and two adult females of K. parahybana , misidentified ( Fig. 26C–D View Fig ).

Diagnosis

The female of K. parahybana resembles that of K. hilaris gen. et sp. nov. by the light median line on prosoma and whitish clypeus ( Fig. 7A View Fig ); however, it can be distinguished from this latter by the five pairs of ventral macrosetae on the anterior tibiae instead of four, small and elliptical copulatory openings ( Figs 7C, E View Fig , 21C) and epigynal plate lacking the median septum. Males may present a body coloration pattern similar to that of K. hilaris gen. et sp. nov.; however, can be easily differentiated by the shorter abdominal projections ( Fig. 8A–B View Fig ), reduced RTA with distal indentations ( Figs 8D, F View Fig , 20D) and by the apical and sinuous embolus ( Figs 8C, E View Fig , 20D).
