D i a g n o s i s: The female of N. roggeveldi is best identified by the conspicuous flat clypeus ( Figs 52, 55 View Figs 51-56 ). Labrum with low and short longitudinal median carina ending in a single medial tooth ( Figs 53, 56 View Figs 51-56 ). First flagellar segment distinctly longer than second (ratio 1: 0.53) ( Fig. 51 View Figs 51-56 ). Hind tibia apically with a row of five to seven slightly downward bent brownish-black spines.

D e s c r i p t i o n

F e m a l e: Body-length: 6.5-8.0 mm (Habitus: Figs 45-46 View Figs 45-50 ). Head: Head black, reddish-brown are: antennal scape directly at the base, flagellum ventrally dark reddish-brown (except first flagellar segment orange), malar area and part of the mandible ( Fig. 47 View Figs 45-50 ). Head slightly broader than long. First flagellar segment significantly longer than second (ratio 1: 0.53) ( Fig. 51 View Figs 51-56 ), all other flagellar segments a little longer than wide. Supraclypleal area with raised longitudinal keel that has its highest point between the antennae. Integument around ocelli impunctate. Clypeus flat, with fine and dense elongate punctation, surface between punctures smooth and shiny ( Figs 52, 55 View Figs 51-56 ). Labrum transversely oval shaped, with a single medial black tooth, surface finely punctate, smooth and shiny between punctation ( Figs 53, 56 View Figs 51-56 ). Mesosoma: Integument black; reddish-brown are: pronotum except laterally, pronotal lobe, spot on tegula ( Fig. 48 View Figs 45-50 ), scutellum with lateral spots, metanotum with medial transverse oval spot and an inverted-U-shaped maculation on the mesepisternum (variable in size and form) ( Fig. 49 View Figs 45-50 ). Scutum and propodeum finely punctate, shiny and smooth between punctures; scutellum and metanotum with slightly finer punctation, matt; scutellum slightly depressed medially and with distinct lateral swelling ( Fig. 49 View Figs 45-50 ). Wings: Wing venation reddish-brown at the base, apically brownish to black, membrane hyaline brown ( Fig. 46 View Figs 45-50 ). Legs: Front leg predominantly reddish-brown with black and brown maculation, mid and hind legs predominantly brownish-black ( Fig. 46 View Figs 45-50 ). Hind tibia apically with a row of five to seven slightly curved brownish-black spines. Metasoma: Metasoma mostly black; reddish-brown are posterior half of T1 and all of T2, on T3-4 with a narrow transverse stripe in front of the marginal zone ( Fig. 50 View Figs 45-50 ). S1-2 reddish-brown. 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. Posterior margin of T5 very slightly concave medially, pseudopygidial area medioapically with long backwards directed black setae surrounded by short appressed silvery hair ( Fig. 54 View Figs 51-56 ). Pygidial plate narrow and flat triangular with rounded tip, finely punctate ( Fig. 54 View Figs 51-56 ).
