Figs 5–7
Polyglossa (Strandiella) flavipes Friese, 1925: 516–517, lectotype ♀ [designated by Eardley 1996] (type locality: Mfongosi, South Africa) (ZMHB), examined.
Diagnosis
The female of S. flavipes can be separated from that of all other species of this group by the following character combination: pronotal lobe yellow (Fig. 5A); facial fovea 3.5 times as long as wide; punctation on scutum dense (i = 0.3 d) (Fig. 5C). The male is characterized by a yellow pronotal lobe (Fig. 6A); narrow facial fovea; hind femur completely dark brown to black (Fig. 6A); anterior of premarginal line long and multi-rowed hairs (Fig. 6F); punctation of scutum dense (i = 0.5 d) (Fig. 6B) and form of S7 (Fig. 7C).

Description
Female
BODY LENGTH. 8.5 mm.
HEAD. Wider than long. Integument brownish, mandibles yellowish-brown to reddish. Face irregularly and sparsely covered with greyish hair, more densely around basis of antennae. Facial fovea about 3.5 times as long as wide. Ocelli in front of the posterior margin of the compound eyes. Clypeus convex with fine punctation, apically sparse (i = 1–2 d), laterally dense (i = 0.5 d). Surface between punctures smooth and shiny (Fig. 5B). Malar area medially narrow, slightly curved. Antennal flagella ventrally yellow, dorsally black. Supraclypeal area delimited by sharp edges and definite.
MESOSOMA. Integument brownish, pronotal lobe yellow. Scutum finely and densely (i = 0.3 d) punctate; surface between punctures smooth and shiny (Fig. 5C). Metanotum less than half as long as scutellum. Propodeum basally and laterally coarsely carinate, apically coriaceous, matt (Fig. 5D). Scutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short, brownish to greyish, erect hair.
WINGS. Yellowish-brown, stigma yellow and wing venation yellowish-brown (Fig. 5A).
LEGS. Integument brownish, hind femur completely dark brown to black. Vestiture and scopa greyish-white (Fig. 5A).
METASOMA. Integument brownish, T2–T3 completely and T1 and T4 partly yellow (Fig. 5E). T2– T4 anterior of premarginal line at least laterally row of short, greyish, erect hair. Hair on T4 dense, getting longer towards posterior. Prepygidial and pygidial fimbriae greyish. Discs of T1–T4 completely impunctate, surface abrasive and matt (Fig. 5E–F).
