Nomada maximiliani KUHLMANN nov.sp. ( Figs 67-76 View Figs 67-72 View Figs 73-76 )

T y p e m a t e r i a l: (2 specimens). Holotype, ♀: South Africa: Middlepos, Hartbeesfontein, 3120CC [31°50´S 20°10´E], 27.viii.1990, leg. V.B. Whitehead, SAM-HYM-B006446 (SAMC). Paratype: South Africa: 1♀, Keiski Mts., 3 km E Farm M´Vera, shale, 31°45´29´´S 19°54´13´´E, 1190 m, 30.viii.2016, leg. M. Kuhlmann (RCMK).

D i a g n o s i s: The female of N. maximiliani is very similar to N. erhardti , but can be distinguished by the completely black clypeus (with a pair of reddish-brown spots in N. erhardti ) ( Fig. 74 View Figs 73-76 ), scutum with finer punctation and almost invisible pair of reddish-brown longitudinal stripes ( Fig. 70 View Figs 67-72 ) (well-defined in N. erhardti ). Moreover, first flagellar segment slightly longer than second (ratio 1: 0.81) ( Fig. 73 View Figs 73-76 ), pygidial plate broad and finely punctate ( Fig. 76 View Figs 73-76 ).

D e s c r i p t i o n

F e m a l e: Body-length: 11.4-13.2 mm (Habitus: Figs 67-68 View Figs 67-72 ). Head: Head black, reddish-brown are: base of antennal scape, ventral side of antennal flagellum (except first flagellar segment orange), lower half of malar area, mandible partly reddish-brown ( Fig. 69 View Figs 67-72 ), lateral margin of labrum ( Fig. 75 View Figs 73-76 ). Head slightly broader than long. First flagellar segment a little longer as the second (ratio 1: 0.81) ( Fig. 73 View Figs 73-76 ), all flagellar segments longer than wide. Supraclypeal area with longitudinal keel raised with highest point between 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 part, punctation fine and dense, between punctures smooth and shiny ( Fig. 74 View Figs 73-76 ). Labrum transversely oval in shape, apical transverse ridge medially with three or four asymmetrically arranged small teeth on upper margin of traverse ridge, surface finely punctate, smooth and shiny between punctation ( Fig. 75 View Figs 73-76 ). Mesosoma: Integument black, reddish-brown are: pronotal lobe, weakly developed pair of longitudinal stripes on the scutum, tegula, axilla ( Fig. 70 View Figs 67-72 ), scutellum with pair of lateral spots on anterior swelling and lower posterior margin, metanotum except lateral margin ( Fig. 71 View Figs 67-72 ) and horseshoe-shaped maculation on the mesepisternum. 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. Legs: Front leg predominantly reddish-brown with black and brown maculation, tibia brownish-black with reddish-brown maculation, mid and hind legs predominantly black with reddish brown maculation ( Fig. 68 View Figs 67-72 ). Hind tibia apically with four straight black spines, outer spine slightly paler and thinner. 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, marginal zone of T3-4 yellowish translucent, T5 posteriorly lighter dark brown ( Fig. 72 View Figs 67-72 ), S1-2 mostly reddish-brown with black maculation, 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, following terga densely punctate and matt, punctation of T2-5 successively coarser, marginal zones of T1-4 smooth and impunctate. Pseudopygidial area on T5 medio-posteriorly with a broad crest of pointed black slightly upwards bent setae, laterally with slightly shorter, pale and backwards directed setae ( Fig. 76 View Figs 73-76 ). Pygidial plate broad and flat triangular with rounded tip, finely punctate ( Fig. 76 View Figs 73-76 ).

M a l e: Unknown.

E t y m o l o g y: The species is dedicated to my respected colleague Maximilian SCHWARZ, Ansfelden ( Austria), who is a famous and esteemed expert for Nomada taxonomy. During the last decades he has supported my work in many ways.

G e n e r a l d i s t r i b u t i o n: Only known from the northern part of the Roggeveld Mountains between Calvinia and Sutherland.

H o s t: Unknown.
