Nomada redivivoides KUHLMANN nov.sp. ( Figs 77-88 )

T y p e m a t e r i a l: (8 specimens). Holotype, ♀: South Africa: 8 km WNW Leliefontein, Fynbos , road side, 30°15´58´´S 18°03´17´´E, 1190 m, 10.ix.2017, leg. M. Kuhlmann ( SAMC) . Paratypes: South Africa: 3♀♀, same label data as holotype ( RCMK) ; 4♀♀, idem., 14.ix.2017 ( RCMK) .

D i a g n o s i s: The female of N. redivivoides is best identified by the medio-longitudinally more dispersed and irregular punctation of the clypeus with interspaces polished and shiny ( Fig. 84 ). In addition, pseudopygidial area apically with a narrow and sparse hair fringe ( Fig. 86 ); pygidial plate narrow and coarsely punctate ( Fig. 86 ).

D e s c r i p t i o n

F e m a l e: Body-length: 10.1-13.2 mm (Habitus: Figs 77-78 ). Head: Head black, reddish-brown are: base of antennal scape, ventral side of antennal flagellum (except first flagellar segment orange), malar area, base and tip of mandible ( Fig. 79 ), labrum usually with small medioapical brown spot (varies from completely black to larger spot) and laterally coloured margin (varies from entirely black to small reddish-brown margin) ( Fig. 85 ). Head slightly broader than long. First flagellar segment longer than second (ratio ventrally 1: 0.76) ( Fig. 83 ), all flagellar segments longer than wide. Supraclypeal area with longitudinal keel raised with highest point slightly below the base of the antenna. Clypeus in lateral view slightly asymmetrically convex, with the highest part in the upper half and flattened in the lower half, coarse irregular punctation, between punctures smooth and shiny, medially small smooth polished surface ( Figs 84, 87 ). Labrum transversely oval in shape, apical transverse ridge medially with three small teeth, the middle tooth is slightly higher arranged than the lateral teeth, surface irregularly punctate, smooth and shiny between punctation ( Figs 85, 88 ). Mesosoma: Integument black, reddish-brown are: pronotum dorsally, pronotal lobe, two longitudinal stripes on both sides of the scutum (they vary from completely black to clear coloured stripes), tegula, axilla ( Fig. 80 ), scutellum with pair of lateral spots on anterior swelling and lower posterior margin, metanotum except lateral margin and horseshoe-shaped maculation on the mesepisternum ( Fig. 81 ). Scutum and propodeum finely punctate, shiny and smooth between punctures; scutellum and metanotum with slightly finer punctation, matt; scutellum medially depressed and laterally with distinct swelling. Wings: Wing venation reddish-brown at the base, apically brownish to black, membrane hyaline brown ( Figs 77-78 ). Legs: Front leg predominantly reddish-brown with black and brown maculation, tibia brownish-black with a medial reddish-brown maculation, mid and hind legs predominantly black with reddish brown maculation ( Fig. 78 ). Hind tibia posteriorly with four to six straight black spines, outer spine sometimes slightly more distance to the others. Metasoma: Metasoma mostly black; reddish-brown are posterior half of T1, all of T2, T3-4 with a narrow transverse stripe in front of the marginal zone, T5-6 posteriorly lighter dark brown ( Fig. 82 ), S1-2 mostly reddish-brown, S3-5 black with small reddish-brown stripe posteriorly. Punctation of T1 more scattered than on following terga, punctures are about as far apart as their diameter. All other terga densely punctate and matt, punctation of T2-6 successively coarser, marginal zones of T1-4 smooth and impunctate. Pseudopygidial area on T5 narrow and with sparse hairs. Medially with brownish-black and laterally with pale setae ( Fig. 86 ). Pygidal plate narrow and flat triangular with a rounded tip, coarsely punctate ( Fig. 86 ).

M a l e: Unknown.

E t y m o l o g y: The species is named after the subgenus Redivivoides MICHENER, 1981 of its assumed host species Rediviva (Redivivoides) variabilis ( KUHLMANN, 2012) . Noun in apposition.

G e n e r a l d i s t r i b u t i o n: Only known from the Kamiesberg Mountains in the wider vicinity of Kamieskroon.

H o s t: Females were observed to inspect and enter nests of Rediviva (Redivivoides) variabilis ( KUHLMANN, 2012) .
