Male harp with three stridulation ribs.  Description. Measurements: male holotype: 20.2 long, 9.2 (2nd), 9.8 (8th) wide, 4.9 (2nd), 6.1 (10th = highest) high. Largest female (with eggs): 21.1 mm long, 9.6 mm (2nd), 10.75 (8th = widest) wide, 5.7 (2nd), 7.5 mm (10th = highest) high. Colouration of tergites black, matte not shiny. Collum and head dark brown (Fig. 20). Depressions of paratergites as well as legs and antennae brownish. Head: Eyes with>60 ocelli. Antennae quite long, protruding as far as leg 8. Antennomeres 1-5 with few setae, 6 densely pubescent (Fig. 13A). Antennomere 6 towards disc with single row of sensilla basiconica (Fig. 13B). Female with 54/56 (13B), male with 74/78 apical cones (Fig. 13C). Gnathochilarium typical for the genus (Fig. 13D), rudimentary lateral palpi with a field of four sensory cones (Fig. 13E). Mandible with the typical shape of the order, inner tooth 3-combed, with six long pectinate lamellae, condylus with a sharp and quite large groove at its apex (Fig. 13F).  Figure 13. Sphaeromimus andohahelasp. n., A, B, D-Ffemale paratype C male paratype, SEM. A right female antenna, lateral view B female antennomere 6 with disc C male antennomere 6 with disc D gnathochilarium, right corner, inner surface E rudimentary right lateral palpus ♀ left mandible, mesal view. Abbreviations: C = condylus; cP = central pads; eT = external tooth; iP = inner palpus; iT = combed inner tooth; LP = rudimentary lateral palpus; mp = molar plate; pL = pectinate lamellae. Collum glabrous except few setae at its margin. Thoracic shield smooth and glabrous, few setae in grooves. Tergites 3-12 smooth, but not glossy, paratergite tips of midbody tergites only weakly projecting posteriorly (Fig. 20). Anal shield massive, well-rounded, lacking pubescent area. Endotergum inner section with numerous short triangular spines and very few setae (Fig. 12B). Between ridge and inner area two rows of weakly impressed, circular cuticular impressions. Externally two irregular rows of marginal bristles (Fig. 12 B-D). Bristles short, barely protruding up to tergite margin. First stigma-carrying plate with a well-rounded apex. Leg 1 with 2 to 4, 2 with 5 or 6, 3 with 10 or 11 ventral spines. Leg pairs 4-21 with 12-14 ventral spines. Coxa process weakly developed (Fig. 14A). Femur 2, tarsus 2.9 times longer than wide.  Figure 14. Sphaeromimus andohahelasp. n., A-Dmale holotype E female paratype. A left leg 9 B anterior telopod, anterior view C right anterior telopod, posterior view D left posterior telopod, posterior view E coxa and prefemur 2 with vulvae. Abbreviations: Cx = coxa; Cx-pr = coxal process; EP = external, lateral plate of vulva; IP = inner, mesal plate of vulva; O = operculum; Pre = prefemur; syn = syncoxite. Scale bars = 1 mm. Male gonopore inconspicuous. Anterior telopod (Fig. 14B, C): Harp carrying three stridulation ribs (Fig. 14B). Shape usual for the genus, telopoditomere 4 as long as 2 and 3 combined, with one large triangular spine and 4 smaller ones (Fig. 14C). Telopoditomere 3 with a spine juxtaposed to process of telopoditomere 2 (Fig. 14C). Posterior telopod (Fig. 14D): Podomere 3 curved, 3 times longer than wide, slightly longer than immovable finger (Fig. 14D). Hollowed-out inner margin with one lobe and four sclerotized spines, posterior aspect with ca. 21 small crenulated teeth. Immovable finger basally wide, apically tapering, 3.1 times longer than wide, strongly curved towards fixed finger. Podomere 1 and 2 with few setae on both sides (Fig. 14D), podomere 3 with a few setae at its margins. Female sexual characters: Second leg pair with well-developed coxal lobe. Vulva massive. Operculum well-rounded, protruding above basal half of prefemur (Fig. 14E). Subanal shield almost divided into two, with strong invagination at apical margin. Washboard with three stridulation ribs on each side.  Intraspecificvariation: The endotergum differs slightly in the development of the cuticular impressions between the specimens from Isaka-Ivondro (Fig. 12B), Malio (Fig. 12C) and Manantantely (Fig. 12D). The specimens from the three localities also differ slightly in their colour pattern: In specimens from Manantantely and Isaka-Ivondro, the head and collum are dark brown, while those from Malio have a brown thoracic shield too. Genetic distances in the COI gene between the three populations are 2.9-4%, while even the two individuals from Malio show a variation at the population level of 3.6%. Future studies involving more localities and specimens should investigate whether or not gene flow occurs between the different populations of Sphaeromimus andohahela.   Etymology.  'andohahela', noun in apposition, after the type locality, the rainforests of the national park Andohahela.  Distribution. Widespread in the lowland and montane rainforests of the northern Anosy and Vohimena mountain chains.
