Perilampus polypori Bouček, 1971: 52-54.

Diagnosis.

Head, mesosoma and metasoma black; female flagellum dark brown. Body size: 2.8-3.4 mm. Head shape in frontal view (Fig. 15A, B ) much wider than high. Head in lateral view not unusually long, without distinct sulcus separating posterior eye margin from temple. Clypeal margin (Fig. 15A, B ) truncate to very slightly convex. Supraclypeal area (Fig. 15B ) slightly transverse (less than 1.5 × as wide as high), sides well defined; in male without oval lateral impressions. Malar sulcus versus anterior margin of malar depression shorter. Frontal keels (Fig. 15A, B ) absent. Face between scrobes and eye (Fig. 15A, B ) smooth. Face between clypeus and eye (Fig. 15A, B ) smooth. Lateral ocellus large (OOL less than twice the largest ocellar diameter). Funicular segments in female (Fig. 15A ): most segments quadrate to transverse. Male scape (Fig. 15B ) slightly widened distally; ventral pores on less than half scape length. Mesosoma (Fig. 15C ) narrow (more than 1.4 × as long as wide). Mesoscutum sculpture (Fig. 15C ) without smooth median tubercle; interspaces smaller than punctures, smooth. Scutellum hind margin (Fig. 15C ) without a double carina, without bilobed protruding projection. Prepectus (Fig. 15D ) wide, dorsal margin longer than pronotal collar; well defined anteriorly (i.e. suture with pronotum very distinct); anterior margin with incomplete row of small punctures.

Comments.

Superficially similar to other small black species, e.g., P. cephalotes (Fig. 5 ), P. maceki , P. minutalis (Fig. 11 ), P. neglectus (Fig. 12 ) or P. tristis (Fig. 18 ), from which it can be separated using the characters given in the key.
