( Figs 9 View FIGURE 9 , 62F View FIGURE 62 )

Afrepipona segregata Selis & Carpenter, 2024: 1 View Cited Treatment , 42, 56 (key), 58 (checklist), figs 17A, B, D, F, 27L, ♂ (non ♀, figs 17C, E)—“ MADAGASCAR … Tulear, Garten Bistro du Sud” ( holotype male NHMW).

Type material examined. HOLOTYPE: ♂ labelled “ MADAGASKAR: TULEAR / Tulear / Garten Bistro du Sud / 19.– 21.10.1996 MADL // Tuleara / leptochiloides Gus. ♂ / J.Gusenleitner,det.2005 // NHMW // Afrepipona segregata / HOLOTYPUS ♂ / Det. Marco Selis [red label]” ( NHMW).

Description of female (hitherto unknown). Habitus in Fig. 9B View FIGURE 9 . Differing from the male (see Selis & Carpenter 2024: 43) as follows: larger size (body length 7.0 mm, fore wing length 6.0 mm), head more robust, clypeus with slightly longer free apical part and deep dense punctures, vertex 2.3× as long as ocellocular distance, cephalic foveae placed in a shallow transverse pit about as wide as one ocellar diameter, yellow pattern reduced on head, coxae and S2, clypeus red with yellow corners.

Distribution. Madagascar: Mahajanga *, Toliara ( Selis & Carpenter 2024) ( Fig. 62F View FIGURE 62 ).

Notes. Selis & Carpenter (2024) described this species based on two specimens with the same collecting data, designating the male as the holotype and the female as the paratype, but noting the doubt in attributing them to the same species given the numerous differences. The examination of new material led to the discovery of the true female of Afrepipona segregata , while the female described by Selis & Carpenter (2024) is attributable to the new species Afrepipona resoluta , described above.

Key to the Malagasy species of Alastor View in CoL

1. Occipital carina evenly curved on gena and mostly parallel to outer eye margin. Pronotal carina forming a dark but translucent lamella, absent only in the middle. Tegula largely impunctate in anterior half. Propodeum with rounded sides and shortly angled above valvula. T1 with an irregular transverse ridge dividing the anterior sloping part and the posterior horizontal part; T2 without V-shaped furrow, in lateral view barely shorter than S2; S2 flattened, smoothly passing into basal furrow; T3 short, posterior margin transverse and barely curved........................................ A. nigroflavus Giordani Soika View in CoL

- Occipital carina diverging from outer eye margin and almost reaching hypostomal carina, then bent at a right-angle. Pronotal carina forming a hyaline lamella, absent in the median third ( Figs 10C View FIGURE 10 , 11C View FIGURE 11 ). Tegula evenly punctate on whole surface. Propodeum with angled sides and long spine above valvula ( Figs 10D View FIGURE 10 , 11D View FIGURE 11 ). T1 evenly rounded, without transverse ridge ( Figs 10E View FIGURE 10 , 11E View FIGURE 11 ); T2 with broad V-shaped furrow, often interrupted in the middle ( Figs 10F View FIGURE 10 , 11F View FIGURE 11 ), in lateral view much shorter than S2; S2 basally convex, shallowly but clearly separated from basal furrow; T3 long, posterior margin strongly curved ( Figs 10B View FIGURE 10 , 11B View FIGURE 11 )............................................................................................... 2

2. More robust appearance, mesosoma 1.45–1.5× as long as wide, T2 wider than long ( Fig. 12A View FIGURE 12 ). Transverse carina of metanotum sinuate and shallowly lobate at sides. Horizontal part of T1 with punctures smaller than those on mesosoma and gradually disappearing posteriorly. Entirely covered in dense pale brassy to silvery pubescence, less evidently in male. Male: ventral face of F11 deeply excised in basal half and convex in apical half, the two parts sharply separated ( Fig. 12A View FIGURE 12 )............................................................................................ A. madecassus Giordani Soika View in CoL

- More slender appearance, mesosoma 1.55–1.85× as long as wide, T2 as long as wide ( Figs 10A View FIGURE 10 , 11A View FIGURE 11 ). Transverse carina of metanotum regular, not lobate at sides. Horizontal part of T1 with punctures similar or larger than those on mesosoma, abruptly disappearing and leaving a broad impunctate apical area ( Figs 10F View FIGURE 10 , 11F View FIGURE 11 ). Dorsal side of head and mesosoma only with long erect setae, pubescence inconspicuous and mostly limited to sutures. Male: ventral face of F11 evenly and weakly convex, not divided in two parts ( Figs 10A View FIGURE 10 , 11A View FIGURE 11 )...................................................................... 3

3. Pronotal carina rounded or obtusely angled on humeri, equally high on dorsal and lateral faces or higher on the latter ( Fig. 11C View FIGURE 11 ); sides of pronotum in dorsal view evenly convex and barely sinuate behind carina. Lateral faces of propodeum with large and dense flat-bottomed cells ( Fig. 11D View FIGURE 11 ). T1 more cylindrical, in dorsal view longer and with parallel sides ( Fig. 11F View FIGURE 11 ), in lateral view anterior face raising vertically and separated from posterior part by an obtuse but clear angle ( Fig. 11E View FIGURE 11 ); T2 more finely and sparsely punctate, interspaces on disc wider than puncture diameter ( Fig. 11F View FIGURE 11 ).
