Material examined: 6 ♂, 3 ♀ Holotype: 1 ♂ (hind end missing), FMMC 7936, Province Toliara, RNI Andohahela parcel I, 440 m, rainforest, 24°37.6’ S, 46°45.9’ E, leg. S. Goodman, 19–28.X.1995GoogleMaps  . Paratypes: 2 ♂, 1 imm., FMMC 8190, Province Toliara, RNI Andohahela parcel I, 1200 m, rainforest, 24°35.0’ S, 46°44.1’ E, leg. S. Goodman, 7–17.XI.1995GoogleMaps  ;

Other material examined: 2 ♂, 1 ♀, FMMC 8191, same data as previous  ; 1 ♂, 2 ♀, FMMC 8202, RNI d’ Andohahela parcel 1, 1875 m, montane rainforest, 24°33.7’ S, 46°43.3’ E, pitfall traps, leg. S. Goodman, 5.XII.1995GoogleMaps  .

Differential diagnosis: the gonopods clearly identify this species ( Figs 59View Figure 59 D–G). H. goodmani  is quite similar in colour to the sympatric H. montanus  sp. n. The latter, however, is much larger and has completely different posterior gonopods.

Description. Measurements: male holotype with 49 rings, 55 mm long, 4.7–4.9 mm wide.

Coloration: head, median part of collum, anterior 3/4 of body rings and anterior half of anal segment dark grey ( Fig. 59AView Figure 59). Posterior margin of body rings, telson and margins of collum light brown ( Fig. 59CView Figure 59). Legs light brown, antennae darker grey ( Fig. 59BView Figure 59). Eyes with 40–44 ocelli ( Fig. 59AView Figure 59).

Anterior gonopod sternite basally wide, apically elevated into a rectangular lobe with a well-rounded tip ( Fig. 59DView Figure 59). Mesal process of coxite slender and protruding ( Fig. 59DView Figure 59). Apical process of telopodite large and well-rounded. Retrorse margin slender, widely projecting above telopodite margin ( Fig. 59FView Figure 59), basally of apical process not projecting ( Fig. 59FView Figure 59).

Posterior gonopod telopodite bent 90° ( Fig. 59GView Figure 59). Projection absent from lateral margin (w, Fig. 59EView Figure 59). Apical process (x) basally extraordinary slender, only twice as wide as sperm canal ( Fig. 59EView Figure 59). Projection of sperm canal (z) long and slender, running parallel to apical process ( Fig. 59GView Figure 59). Tip sharp-edged. Membranous lobe (y) large and well-rounded ( Fig. 59EView Figure 59).

Distribution and ecology: this species is only known from the Anosy Mountains, north of the Isaka-Ivondro corridor ( Fig. 54View Figure 54).

Etymology: goodmani  , adjective, named after Dr. Steven M. Goodman who collected this and numerous other remarkable Malagasy millipede species.
