Description of Capicola hantamensis Michez & Kuhlmann sp. nov.

Type material. Holotype male SANC, 3 females paratypes, 7 males paratypes, CKUM: “ South Africa, 28km N Calvinia , Sandveld, 31°12’09’’S 19°50’05’’E, 885m, 06.X.2006, leg. M. Kuhlmann”.

Additional material. 2 females, 1 male, OOLL: “ South Africa, N Cape, 50km Loeriesfontein [30°58’S 19°27’E], 14.X.1999, leg. Marek Halada ” .

Etymology. Named after the locus typicus, the Hantam Mountains.

Diagnosis. Like other Dasypodaidae , Capicola hantamensis has a short pointed glossa with all segments of the labial palpus similar to one another and two submarginal cells (the first longer than the second). Like other Capicola , the female Pp has a strong elevated medial area and the male S6 has medio-apical and lateral processes. Capicola hantamensis differs from all other Capicola by having yellow legs, yellow clypeus in the male and an inner blade to the gonostylus. Females show the diagnostic combination of rugose propodeal triangle and inner Tb2 spur finely serrate.

Flagellum ventrally reddish or yellow, dorsally brownish. Clypeus, face and genal area with white, erect hairs. Vertex shiny. Labial palpus two-thirds as long as maxillary palpus, reaching beyond apex of glossa. Maxillary palpus longer than galea. Outer surface of galea smooth. Malar area shorter than A2. Clypeus glabrous; three times as wide as long; with deep punctures (i=d), denser at base, smooth between punctures. Compound eyes converging slightly below. Flagellum twice as long as scape. Mesosoma. L= 2.1mm. W (between tegulae)= 1.3mm. Integument black. Mesoscutum, scutellum, metanotum, propodeum and mesepisternum with a few short whitish hairs.

Floral visitation. All females were collected visiting flowers of Wahlenbergia sp. (Campanulaceae) . Males were patrolling along patches of Wahlenbergia sp.

Biotope. The bees were found along a roadside with shrubs and on the neighbouring sparsely vegetated pasture (Sandveld) with large areas of open sandy ground ( Fig. 3).

Distribution. Only known from two localities near Calvinia and Loeriesfontein in the Hantam Mountains ( Fig. 4 ).

Phylogenetic analysis

The heuristic search based on the data matrix (table 1) yielded two equally parsimonious trees of length=54, CI=0.5370 and RI=0.6835. A cladogram of one tree is displayed in Fig. 5 . Capicola hantamensis shares many plesiomorphies with Eremaphanta fasciata (characters 2, 4–5, 7–10, 12–15, 17, 19, 20). It is the sister species of all other Capicola , which share outstanding spines on spur of Tb 2 female, black hind leg male and black clypeus male.
