Diagnosis

The female of S. roggeveldi sp. nov. can be separated from other species of this group by the combination of the following characters: supraclypeal area and clypeus densely and distinctly punctate, partly superficially sculptured and matt ( Fig. 26B View Fig ), scutum densely but relatively finely punctate ( Fig. 26 View Fig C–D), stigma brown, apical margins of metasomal terga black, terga minutely punctate ( Fig. 26E View Fig ). The male

is characterized by an unmodified antenna, hind tibia apically broadened inside, forming a ± right angle ( Fig. 27G View Fig ), S4–S5 with long apical hair fringes ( Fig. 27E View Fig ) and the form of S7 ( Fig. 27D View Fig ).

Only one male of this species was collected, near Sutherland, but a single specimen from the Hantam Plateau about 130 km further NW probably represents the female of this species. This female is diagnosed and described here, but because of the uncertainty it is not included in the type series.

Etymology

Named after the Roggeveld Mountains between Calvinia and Sutherland where this species was found.

Description

Female

BODY LENGTH. 4.8 mm.

HEAD. Head wider than long. Integument black, except part of mandibles dark reddish-brown. Face sparsely covered with long, greyish, erect hair ( Fig. 26B View Fig ). Clypeus almost flat with coarse, shallow and sparse punctation (i = 1–2 d); surface between punctures apically smooth and shiny, basally superficially shagreened and slightly matt ( Fig. 26B View Fig ). Malar area medially narrow, almost linear. Antenna dorsally blackish-brown, ventrally yellowish-brown.

MESOSOMA. Integument black. Mesoscutal disc between punctures superficially reticulate but shiny; disc densely (i = 1–2 d), shallowly and finely punctate ( Fig. 26 View Fig C–D). Metanotum slightly shorter than basal area of propodeum, apically with narrow carinate depression ( Fig. 26D View Fig ). Propodeum basally shallowly carinate ( Fig. 26D View Fig ). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short, greyish, erect hair ( Fig. 26A View Fig ).

WINGS. Slightly yellowish-brown; wing venation and stigma brown.

LEGS. Integument completely black to dark reddish-brown. Vestiture greyish-white, scopa greyish-white, dorsally blackish ( Fig. 26A View Fig ).

METASOMA. Integument black, apical margins of terga partly and narrowly translucent reddish-brown ( Fig. 26E View Fig ). Disc of T1 without hair; following terga with very short but increasingly more and longer hair; T3 basally with a narrow and very sparse band of very fine, short, erect hair; apical tergal hair bands missing on all terga ( Fig. 26E View Fig ). Prepygidial and pygidial fimbriae greyish-brown. T1 very finely, superficially and sparsely (i = 2–3d) punctate, between punctures superficially sculptured but shiny; T2–T4 shiny, with dense, fine, superficial punctation; T2–T4 with superficially sculptured, broad apical tergal depression ( Fig. 26E View Fig ).

Male

BODY LENGTH. 5.0 mm.

HEAD. Head slightly wider than long. Integument black, except mandible partly dark reddish-brown. Face densely covered with long, greyish-white, erect hair. Malar area medially narrow, almost linear. Antenna dorsally dark brown, ventrally yellowish-brown except last three flagellar segments almost completely dark brown ( Fig. 27A View Fig ).

MESOSOMA. Integument black. Mesoscutal disc between punctures strongly reticulate and matt; disc finely, very shallowly and almost invisibly, sparsely punctate (i = 2–3 d). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with long, greyish, erect hair ( Fig. 27A View Fig ).

WINGS. Slightly yellowish-brown; wing venation and stigma brown.

LEGS. Integument black or dark reddish-brown ( Fig. 27A View Fig ). Hind tibia inside apically broadened, with an almost rectangular edge ( Fig. 27G View Fig ). Vestiture greyish-white.

METASOMA. Integument black, apical margins of terga partly narrowly translucent dark reddish-brown ( Fig. 27C View Fig ). Discs of T1–T3 without hair, laterally sparsely covered with short, erect greyish-white hair; following terga with sparse and very short but increasingly more and longer hair; apical tergal hair bands missing on all terga ( Fig. 27C View Fig ). T1 and following terga sparsely (i = 2–3 d) and almost invisibly very finely and superficially punctate, between punctures superficially sculptured and shiny; terga with broad, superficially sculptured but shiny apical tergal depression ( Fig. 27C View Fig ). S3 and particularly S4–S5 with long apical hair fringes ( Fig. 27E View Fig ).

TERMINALIA. Genitalia ( Fig. 27B View Fig ), S7 ( Fig. 27D View Fig ) and terminal plate of S8 ( Fig. 27F View Fig ) as illustrated.
