Notes.

Hyctiota banda Strand, 1911 is based on a juvenile (SMF 2511 in SMF, examined) and not easily placed. Its being a baviine is suggested by its elongate body (most like that of Indopadilla or Stagetillus ), plurident chelicerae, and Asian origin. Its macrosetae sockets resemble those of baviines (Figs 21-23 ). It lacks the thoracic bulge and ridged chelicerae of Indopadilla , and the flat carapace of Padillothorax . Like Stagetillus , the fovea is displaced slightly to the posterior. The two dark bands running through the PLE shown in Strand’s (1911) original figure (no longer visible in specimen) resemble those of male S. opaciceps . The carapace is widest posteriorly, though not so clearly as in Figs 15 and 16 . Although its synonymy with Stagetillus is not certain, by placing it with Stagetillus , a salticid genus otherwise incertae sedis is provisionally settled.

Diagnosis.

Carapace distinctive in shape, widest point toward the posterior, approx. half way between the back eyes and the pedicel, and in colour, orange or yellow with the white digestive diverticulum showing beneath the transparent ocular quadrangle. Palp much like that of Bavia , with short blade-like embolus.
