Diagnosis.
Adult males of Nannaria kassoni sp. nov. are distinct from other Nannaria and the nearby Nannaria sp. nov. ‘Cratagae’ ( Nannaria wilsoni species group) based on the following combination of characters: Gonopods. Gonopodal acropodite curving medially before apex, not straight as in Nannaria sp. nov. ‘Cratagae.’ Apex with distinct constriction (Fig. 104A View Figure 104 , red arrow), tip sharp, with acuminate, triangular lateral flange, not blunt with small lobed lateral and medial flanges as in N. cryomaia sp. nov. Acropodite with expanded, laminate, medial flange (Fig. 104A View Figure 104 , red triangle). Prefemur with medially curving prefemoral process, paralleling curve of acropodite, not straight, acicular as in Nannaria sp. nov. ‘Cratagae.’ Prefemoral process arising dorsolaterally from pronounced curving prefemoral spine, not arising from prefemur with short, triangular prefemoral spine as in N. cryomaia sp. nov. Telopodite basal zone height ca. 1/3 length of acropodite, not> 1/3 as in N. cryomaia sp. nov., and not ca. 1/4 length as in Nannaria sp. nov. ‘Cratagae.’ Color. Tergites with orange stripes (Fig. 105 View Figure 105 ). Dark brown background. Dorsum of collum smooth with orange margin.
