Description.

-As in Key 1. A distinctive species recognizable by its very short fastigium (Fig. 86) and round, bulging eyes. Of medium size, integument rugose. Antennae slightly longer than head and pronotum together, weakly expanded and flattened at base. Frons convex in profile, practically parallel-sided with wavy margins; fastigial constriction very weak. Fastigium very broad and short. Eyes round, large, bulging. Pronotum weakly tectiform, its surface callose and rugose; medial carina smooth, lateral carinae callose and parallel in prozona, weaker and feebly divergent in metazona. Lateral lobes deeper than long, lower margin sinuate. Tegminal apices extend beyond hind knees of folded posterior femora. Venation fairly dense with incomplete false veins (Fig. 77). Coloration mottled reddish chocolate-brown and ivory-white with brown spots. Hind femur reddish-brown with blackish dots, knee blackish. Hind tibia dirty brown with black spines.

Wings infumate, sometimes rose at base. Table 4 gives morphometric data for callosa .

Discussion.

-This species and S. granulifera Uvarov, 1953 form a bridge morphologically between Sumba and Panzia .

Distribution.

-ANGOLA, D.R. CONGO.

Editorial comment.

- Johnsen 1984: 307 suggested that Rhabdoplea callosa might be synonymous with Sumba roseipennis , thus foreshadowing Popov’s transfer to the latter genus.
