( Figs 60A View FIGURE 60 , 61B–D View FIGURE 61 , 66J View FIGURE 66 )

Giordania nigra Gusenleitner, 1995: 203 , 209, figs 4, 6, ♀ —“ Madagaskar, Ste. Marie, Fluss Manandriana ” (NHMW).

Type material examined. HOLOTYPE: ♀ labelled “ MADAGASKAR: Ste.Marie / Fluss Manandriana / 14.– 25.11.1994 MADL // Giordania / nigra nov. spec. ♀ / J.Gusenleitner,det.1995 / Holotypus // Holotypus [red label] // NHMW ” ( NHMW).

Distribution. Madagascar: Fianarantsoa *, Toamasina ( Gusenleitner 1995) ( Fig. 66J View FIGURE 66 ).

Notes. The specimens examined show some variability in size and apex of T2 , as the two specimens from Perinet are larger (body length 12.5–13.0 mm) and have a simple T2 margin ( Fig. 61D View FIGURE 61 ), while the others, including the holotype, are smaller (body length 10.0–11.0 mm) and T2 has a very thin dark lamella visible at high magnification ( Fig. 61C View FIGURE 61 ). However, the size and the metasomal lamellae are variable in other related species (e.g., O. hyalinelamellatus ) and there is no other morphological difference, therefore in the absence of males to compare all specimens are considered to belong to the same species .
