Scrapter mellonholgeri Kuhlmann sp. nov.
The female of S. mellonholgeri Kuhlmann sp. nov. can be separated from all other species of this group by the combination of the following characters: head distinctly broader than long; supraclypeal area and clypeus superficially sculptured and slightly matt, coarsely and densely to sparsely punctate ( Fig. 6B View Fig ); scutum mostly relatively sparse and slightly coarsely punctate ( Fig. 6 View Fig C–D); propodeum basally just slightly ( Fig. 6 View Fig E–F); stigma brown; apical margins of metasomal terga slightly translucent dark reddishbrown; terga densely and finely punctate ( Fig. 6G View Fig ). The male is characterized by an unmodified antenna; coarsely and densely punctate scutum; finely and densely punctate metasomal terga ( Fig. 7C View Fig ); hind tibia apically broadened inside, forming a spine ( Fig. 7E View Fig ); third hind tarsus unmodified ( Fig. 7G View Fig ) and the shape of S7 ( Fig. 7F View Fig ).
This species is dedicated to my (MK) friend (High Elvish [Sindarin]: mellon; noun in apposition) Holger Heinrich Dathe, expert in bees of the genus Hylaeus and former director of the Senckenberg German Entomological Institute, Müncheberg, in recognition of his ground breaking contributions to Afrotropical taxonomy of Hylaeus .

BODY LENGTH. 4.4–5.3 mm.
HEAD. Head slightly wider than long. Integument black, except part of mandibles dark reddish-brown. Face sparsely covered with long, greyish, erect hair ( Fig. 6B View Fig ). Clypeus convex with relatively coarse but dense (i = 0.5–1 d) punctation; surface between punctures superficially reticulate and slightly matt ( Fig. 6B View Fig ). Malar area medially narrow, almost linear. Antenna dorsally blackish-brown, ventrally yellowish-brown.
MESOSOMA. Integument black, tegula reddish-brown. Mesoscutal disc between punctures to a variable degree reticulate and slightly matt; disc relatively sparsely (i = 2–3 d) and relatively finely to slightly coarsely punctate ( Fig. 6D View Fig ); sometimes disc shinier and with denser (i = 1 d) punctation ( Fig. 6C View Fig ). Metanotum about as long as basal area of propodeum, apically with narrow carinate depression ( Fig. 6 View Fig E–F). Propodeum basally indistinctly and very finely carinate ( Fig. 6F View Fig ), sometimes only laterally
WINGS. Brownish; wing venation and stigma brown.
LEGS. Integument black. Vestiture greyish-white; scopa greyish-white, dorsally brownish.
METASOMA. Integument black, apical margins of terga narrowly black to translucent dark reddish-brown ( Fig. 6G View Fig ). Disc of T1–T2 glabrous; following terga with very short but increasingly more and longer hair; T3 basally with a very narrow and sparse band of very fine, short, erect hair; apical tergal hair bands missing on all terga ( Fig. 6G View Fig ). Prepygidial and pygidial fimbriae relatively short, greyish-brown. T1 finely and relatively densely (i = 1–1.5 d) punctate, between punctures superficially sculptured and slightly matt; following terga more matt; T2–T4 with superficially sculptured and slightly matt apical tergal depression ( Fig. 6G View Fig ).
BODY LENGTH. 4.6–5.5 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 completely or largely brown.
MESOSOMA. Integument black. Mesoscutal disc between punctures reticulate and slightly matt to matt; disc sparsely (i = 1.5–3 d) and coarsely punctate. Mesoscutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with long, greyish, erect hair ( Fig. 7A View Fig ).
WINGS. Slightly yellowish-brown; wing venation and stigma brown.
LEGS. Integument black, fore tibia anteriorly dominantly yellowish-brown. Hind tibia inside apically broadened, with a spine ( Fig. 7E View Fig ). Hind basitarsus medially slightly broadened ( Fig. 7G View Fig ). Vestiture greyish-white.
METASOMA. Integument black to dark reddish-brown, apical margins of terga partly narrowly translucent dark reddish-brown ( Fig. 7C View Fig ). Discs of T1–T2 without hair, following terga with short but increasingly more and longer hair; T3 and T4 basally with a very narrow and sparse band of short greyish, erect hair; apical tergal hair bands missing on all terga ( Fig. 7C View Fig ). T1 finely, following terga relatively coarsely but densely (i = 0.5–1 d) punctate; superficially reticulate and slightly matt; T2–T4 with narrow, superficially sculptured but shiny apical tergal depression ( Fig. 7C View Fig ). S3 and particularly S4–S5 with sparse, long apical hair fringes.
Recorded from the northern part of the Roggeveld Mts and the Kamisberg Mts.
