Wesener et al., 08.VI.2007 GoogleMaps ; 1 ♀, ZMH W049 View Materials A ; same data as previous ; 1 ♀, ZMUC W049 View Materials A, same data as previous .

Other material examined: 2 ♀, 4 imm., W049A, same data as previous, but stored as vouchers at University Antananarivo.

Differential diagnosis: A. antanosy differs from all congeners in the absence of male coxal processes ( Fig. 47B View Figure 47 ). While the anterior gonopods are very similar in all species of the Alluviobolus ( Figs 47D, F View Figure 47 ), are the posterior gonopods in A. antanosy rectangular apically ( Fig. 47G View Figure 47 ), compared with acute telopodite tips in A. laticlavius ( Fig. 44H View Figure 44 ) and in A. tsimelahy ( Fig. 46L View Figure 46 ).

Description. Measurements: males with 42–44 body rings, circa 43–47 mm long, 3.2–3.8 mm wide. Females with 43 or 44 body rings, 54–62 mm long, 5.0– 5.5 mm wide.

Coloration on mesozonites dark grey, metazonites red ( Fig. 47C View Figure 47 ). Rings dorsally with a slender orange stripe. Head, legs, and posterior part of telson red ( Figs 47 View Figure 47 A–C). Antennae and anterior part of telson dark grey ( Figs 47A, C View Figure 47 ). Eyes with 22–25 ocelli arranged in 4 or 5 rows ( Fig. 47A View Figure 47 ). Antennae protruding back to ring 5 ( Fig. 47A View Figure 47 ). Male coxal processes absent, coxa 3 of slightly conical shape ( Fig. 47B View Figure 47 ). Preanal process absent ( Fig. 47C View Figure 47 )

Anterior gonopod sternite elevated into a broad triangular lobe. Tip well-rounded ( Fig. 47D View Figure 47 ). Coxite and telopodite inconspicuous ( Fig. 47F View Figure 47 ).

Posterior gonopods: telopodite membranous fringe absent ( Fig. 47E View Figure 47 ). Apical sclerite (x in Fig. 47G View Figure 47 ) wide, rectangular. Tip broadly rounded, basally elongated to a thin spine ( Fig. 47E View Figure 47 ).

Distribution and ecology: widely distributed in rainforests of Southeastern Madagascar. A. antanosy was collected in the Andohahela and Vohimena mountain chain as well as in the lowland littoral rainforest of Sainte Luce and the isolated Ambatotsirongorongo Mountain ( Fig. 43 View Figure 43 ). All specimens were found on the soil surface.

Etymology: antanosy, noun in apposition, after the Malagasy Antanosy people, who live around Tolagnaro (Fort Dauphin) where this species was collected.
