Description. FEMALE ( Fig. 62View FIGURES 62 – 70). Length about 2.8 mm. Head with face and frontovertex variable in color depending on angle of light, mostly uniformly reddish-coppery from direct view ( Fig. 64View FIGURES 62 – 70) but increasingly green with less distinct reddish-coppery luster from increasingly oblique angle; frontovertex distinctly differentiated by difference in sculpture at level about midway between toruli and anterior ocellus, with larger, and more isodiametric meshlike reticulations dorsad level and smaller, more transverse reticulations ventrad level, the sculpture between frontovertex and torulus in particular more transverse reticulate-rugose; in lateral view lower face and gena posterior to malar sulcus similarly strongly sculptured and colored; in dorsal view OOL almost 1.3× maximum diameter of posterior ocellus. Antenna ( Fig. 68View FIGURES 62 – 70) with scape, pedicel, and basal five funiculars lighter yellow compared to darker brown apical three funiculars and clava; fl 1 slightly but distinctly longer than wide, fl 4 about 0.7× length of fl 2 and fl 3, and funiculars increasing in width and beyond fl 4 decreasing in length such that apical funicular slightly transverse in dorsal view; apical funicular ventrally extending under clava as apically tapered, ventrally bare and shiny, finger-like projection to claval apex; clava with slender, terminal, setose, spiniform process. Mandible with two similar teeth ventrally and shallowly concave, obliquely angled margin dorsally.

Pronotal collar ( Fig. 63View FIGURES 62 – 70) in lateral view shallowly concave and in dorsal view not distinctly “shoulder-like” posterolaterally; almost uniformly coarsely punctate-reticulate mediolongitudinally, the reticulations only slightly larger posteriorly than anteriorly, and similarly reddish-coppery as face, with extreme posterior margin greenish and large, elongate-triangular, blue to purple or reddish-violaceous regions posterolaterally, these virtually smooth except for some effaced meshlike sculpture, with numerous distinct setae, and with longitudinal inner margins conspicuously differentiating quadrangular median sculptured region over length of collar. Mesoscutum ( Fig. 63View FIGURES 62 – 70) anteriorly between incomplete notauli similarly reddish-coppery and punctate-reticulate as pronotum, but posteriorly with much larger reticulations and more reddish-violaceous along transscutal articulation and posteriorly on lateral lobes; scutellar-axillar complex ( Fig. 65View FIGURES 62 – 70) reddish-coppery except anterior crenulate region between axillae bright green to bluish-green, axilla with reticulate dorsal surface longer than medial crenulate region between axillae, and with obliquely angled posterior surface increasingly finely sculptured to smooth ventrally, and scutellum comparatively flat dorsally, punctulate anteromesally, but with larger, more distinctly reticulate sculpture laterally and with transverse reticulations posteriorly. Tegula yellow. Macropterous; fore wing ( Fig. 69View FIGURES 62 – 70) marginal vein about 7.5× length of stigmal vein; apex of postmarginal vein indistinct, but at most extending only slightly beyond level of uncus; uncus ( Fig. 70View FIGURES 62 – 70) diverging from stigmal vein before apex so as to differentiate distinct stigma similar in length to uncus, and apex separated from posterior margin of postmarginal vein by distance at most equal to width of postmarginal vein or uncus and much less than width of uncus plus stigma; costal cell ventrally with up to 8 setae within about basal third; disc ( Fig. 69View FIGURES 62 – 70) with oval brown region behind venation to medial fold and with somewhat lighter brownish infuscation posterior to cubital fold, but narrowly hyaline along marginal vein, with distinct brown setae except for much shorter, more spiculate setae apically and behind medial fold, and with narrow bare band along parastigma and marginal vein, and elongate bare region dorsally beyond stigmal vein ( Fig. 70View FIGURES 62 – 70); marginal fringe distinct only along posteroapical margin. Prepectus extensively setose with relatively inconspicuous, short white setae. Mesepimeron bare along posterior margin ( Fig. 66View FIGURES 62 – 70). Metapleuron bare, with about ventral half reticulate and dorsal half smooth and shiny ( Fig. 66View FIGURES 62 – 70). Metasternum comparatively long, with base of mesocoxa distinctly anterior to, and apex of mesocoxa about level with base of metaxcoxa. Legs ( Fig. 62View FIGURES 62 – 70), including coxae, mostly orange to somewhat brownish-orange, but basal three tarsomeres of meso- and metatarsi white; metacoxa dorsobasally with patch of several short white setae. Propodeum ( Fig. 67View FIGURES 62 – 70) with crenulate band along anterior margin recurved posteromedially into anteriorly broad, posteriorly tapered, V-shaped rugose region on either side of complete median carina; panels otherwise smooth and shiny, and callus smooth and shiny; callus anteriorly and propodeal plical region posteriorly and laterally between foramen and spiracle purple to blue or reddish-violaceous under some angles of light, but callus posterior to level of spiracle and plical region anteriorly variably extensively green or with some coppery luster depending on angle of light.

Petiole ( Fig. 67View FIGURES 62 – 70) dorsally brown with slight greenish luster, shiny and almost smooth though with subeffaced sculpture, and about 1.4× as long as median width. Gaster ( Fig. 62View FIGURES 62 – 70) uniformly dark brown; presyntergal tergites isodiametric meshlike coriaceous except smooth along posterior margins, with Gt 2 slightly longer than Gt 3.

MALE ( Fig. 71View FIGURES 71 – 76). Length = 1.4–3.0 mm. Head ( Fig. 72View FIGURES 71 – 76) color variable, sometimes with frontal surface mostly green though usually variably extensively blue to bluish-green ventrally and more distinctly green with slight coppery luster dorsally, and vertex usually with some reddish-violaceous luster, at least in region of ocellar triangle; sculpture of face and frontovertex similar to female. Antenna ( Figs 71, 75View FIGURES 71 – 76) with scape and pedicel often yellowish but at least scape somewhat lighter brown than flagellum; 11 -segmented with flagellum having 6 long rami; fl 1 anelliform; fl 2 –fl 7 each with long ramus, with f 12 –fl 5 anelliform, fl 6 slightly longer than wide and fl 7 about 3–4 × as long as wide; fl 8 about 4 –5.5× as long as fl 7 and about 1.5–1.8× as long as fl 9 (terminal flagellomere); flagellum ( Fig. 75View FIGURES 71 – 76) with conspicuous, long white setae along inner surfaces of rami and funiculars, and more uniformly around clava. Mandible similarly structured as for female. Maxillary and labial palpi yellowish-brown to dark brown but at least apical maxillary palpomere white.

Pronotum green to bluish-green or with coppery to reddish-violaceous lusters medially and posterolaterally, the color difference sometimes differentiating posterolateral regions similar to female but uniformly mesh-like reticulate ( Fig. 72View FIGURES 71 – 76). Mesonotum mostly green with some coppery luster to variably extensively coppery to reddishviolaceous; mesoscutum meshlike reticulate, with smaller reticulations anteriorly between incomplete notauli and large reticulations posteriorly; scutellum ( Fig. 73View FIGURES 71 – 76) somewhat flatter dorsally than female and more uniformly meshlike reticulate, though reticulations larger laterally and posteriorly and all much smaller than on mesoscutum posteriorly; axilla similarly mesh-like reticulate anteriorly as female but more distinctly coriaceous posteroventrally. Fore wing ( Fig. 76View FIGURES 71 – 76) with marginal vein about 5.7– 7 × as long as stigmal vein; hyaline; disc with much broader bare region behind parastigma and marginal veins than female and comparatively inconspicuously setose with short white setae and marginal fringe distinct only along posteroapical margin; uncus slender and more distantly separated from wing margin than for female. Prepectal, mesepimeral and metapleural setation, metapleural sculpture, and relative placement of mesocoxa as for female ( Fig. 74View FIGURES 71 – 76). Legs ( Fig. 71View FIGURES 71 – 76) with coxae dark with distinct metallic luster; femora and tibiae brown to dark brown and at least metafemur and sometimes all femora and tibiae with variably distinct purple luster, except basal four tarsomeres of middle and hind legs white and apical tarsomeres dark brown. Propodeum ( Fig. 73View FIGURES 71 – 76) with similar colors as female and with complete median carina, but median sculptured region much less developed than for female, distinctly coriaceous to shallowly reticulate anteriorly between spiracles and usually narrowly on either side of median carina, the panels otherwise shiny and smooth or with at most subeffaced mesh-like sculpture.

Petiole ( Figs 73, 74View FIGURES 71 – 76) sometimes dark brown, but usually with variably distinct blue to bluish-green lusters under at least some angles of light, smooth and shiny, and about 1.6– 2 × as long as wide.

Biology. Unknown.

Remarks. Notanisus vanharteni  and N. yemenensis  comprise a species pair from the Arabian Peninsula that are more similar to N. kansensis  and N. oulmesiensis  than the Sub-Saharan African species (see under latter species). Females are quite similar, but the unique female of N. yemenensis  differs conspicuously from that of N. vanharteni  in head and mesosomal color, structure and sculpture of the differentiated posterolateral region of the pronotum, sculpture pattern of the median sculptured region of the propodeum, and structure of the stigmal vein. Additional females are required to evaluate variation and which features are truly differential. Distinct color, structural or color features do not appear to distinguish males of the two species and for this reason a separate description or images of the single N. yemenensis  male is not given.
