8C3987E12A41FFDDE06FFD8EFEF5FA2E.taxon	diagnosis	DIAGNOSIS: A medium-sized Spinomantis (adult male SLV 32 – 35 mm), with type 2 femoral glands; vomerine teeth; a reticulated dorsal pattern composed of dark round spots on a lighter background; a dark throat with light spots; a singular subgular vocal sac in males; inner and outer metatarsal tubercles; SVL / FT $ 1.4; webbing formula I 0.5 to 1 – 0.75 to 1 II 0 to 0.5 – 1 to 1.5 III 0.5 to 1 – 2 IV 2 – 0.25 to 0.75 V; and no dermal spines on fore or hind limbs (table 1). Spinomantis brunae can be distinguished from all other Spinomantis species by the following characters. S. aglavei, S. fimbriatus, S. massorum, S. tavaratra sp. nov., and S. phantasticus all have hind limb dermal spines that are absent in S. brunae. Spinomantis bertini is much smaller (males SVL 22 – 23 mm), and has only rudimentary webbing on the hind feet. Spinomantis elegans and S. microtis are larger (male SVL 34 – 60 mm) and males lack femoral glands. In addition, S. elegans lacks an outer metatarsal tubercle, and S. microtis has completely webbed feet. Spinomantis guibei has distinctive markings: the ventral limbs are white with black blotches, and the dorsal body has longitudinal dark lines (both marking features absent in S. brunae). Spinomantis guibei also has more reduced webbing: the 4 th internal toe has 3 phalanges without webbing compared to 1 – 2 for S. brunae. Spinomantis nussbaumi sp. nov., and S. peraccae can be distinguished from S. brunae by their large adult male body size (SVL 35 – 57 mm); throat color (S. nussbaumi sp. nov. brilliant white with dark spots, S. peraccae pale yellowish white with or without dark spots); and smaller foot in relation to body size (S. nussbaumi sp. nov. and S. peraccae SVL / FT # 1.4).	en	Cramer, Abigail F., Rabibisoa, Nirhy H.

Tympanum light brown. Flanks dark brown with light brown small spots. Arms with five dorsal dark brown transverse stripes of uneven width. Legs light brown with 12 dark brown transverse stripes of uneven width. Some of the broader pale brown bands contain within them additional darker brown blotches. In the natural resting posture, the dorsal stripes on the hind limbs line up to form three longitudinal stripes. Ventral arms and legs light brown. Throat light brown with yellowish-white spots. Venter brown. Femoral glands light brown in external view and yellowish white in internal view. COLORATION IN LIFE: The dorsal pale brown coloration (in preservative) is olive green in life, and the pale flank spots are white in life. The digit and toe pads are each marked TABLE 1 Morphometric data for Spinomantis brunae. All measurements in mm. MRSN specimen data from Andreone et al., (1998). with a pair of white spots. The iris is creamy white in color. VARIATION: Morphometric variation is summarized in table 1, which includes the holotype. All specimens agree with the description of UMMZ 198411 with the following exceptions. Femoral glands vary in size from 8.5 – 9.1 mm in length and 3.4 – 3.7 mm width, separated by 0.8 – 1.3 mm, with approximately 75 – 110 granules visible in external view. Inner metatarsal tubercle range from 1.2 – 1.4 mm in length. Foot webbing variation: I 0.5 to 1 – 0.75 to 1 II 0 to 0.5 – 1 to 1.5 III 0.5 to 1 – 2 IV 2 – 0.25 to 0.75 V. The holotype END and NSD measurements given by Andreone et al. (1998) are not within the range of the adult males examined by us (see table 1), possibly due to difference in measurement methodology. Characters of adult females are unknown. Juveniles UMMZ 198404 and 198406 have poorly defined supratympanic ridges, yellowish-white venters in preservation, and a dorsal pattern of reticulate spots that are not as closely spaced together compared to the adult coloration.	en	Cramer, Abigail F., Rabibisoa, Nirhy H.

8C3987E12A41FFDDE06FFD8EFEF5FA2E.taxon	discussion	REMARKS: One UMMZ specimen was collected during the day (1100 hours) on a leaf, but all others were collected at night (2100 – 2300 hours) on leaves, branches, or rocks. All specimens were found in close proximity to small fast-flowing streams, in areas with large to massive rock boulders and rock crevices at the waters edge. One male (RAN 36729, UMMZ 198408) was found vocalizing at 2100 hours on a branch at 0.5 m height off the ground by a small stream. The call is a short one-second pulse, sounding like a rapid metallic trill, which is repeated every 5 – 10 seconds.	en	Cramer, Abigail F., Rabibisoa, Nirhy H. C., Raxworthy, Christopher J.

8C3987E12A4BFFD6E2DEFC61FEF3FDBD.taxon	diagnosis	DIAGNOSIS: A medium-sized Spinomantis (adult male SLV 30 – 36 mm), with type 2 femoral glands in adult males; a singular subgular vocal sac in males; NSD, 2 mm; dark spots on throat and venter; inner and outer metatarsal tubercles; vomerine teeth; a tibiotarsal extension that extends between the nostril to beyond the snout tip, 2 to 2.5 phalanges free of webbing on the exterior 4 th toe, and simple dermal spines, 1 mm length along the posterior margin of the tarsus (table 3). Spinomantis tavaratra can be distinguished from the following species: S. peraccae, S. brunae, S. elegans, S. microtis, S. bertini, and S. nussbaumi sp. nov. by presence of dermal spines on the tarsus. Spinomantis tavaratra can be distinguished from S. phantasticus by the lack of supraocular dermal spines $ 0.5 mm and lack of other prominent spines on the head or dorsum. Spinomantis tavaratra can be distinguished from S. aglavei and S. fimbriatus (see table 4) by its dermal spines on its hind limbs that do not exceed 1 mm in length (S. aglavei and S. fimbriatus spines exceed 1 mm, Glaw and Vences, 1997); absence of dermal spines with multiple points (S. aglavei spines with multiple points); smaller SVL (S. tavaratra SLV 30 – 36 mm, S. aglavei 40 – 51 mm, S. fimbriatus 36 – 39 mm); and tibio-tarsal extension that may extend beyond the nostrils (S. aglavei and S. fimbriatus to nostrils). Spinomantis tavaratra can be distinguished from S. massorum by the shorter snout (S. tavaratra NSD, 2 mm; S. massorum NSD. 2.1 mm); dark markings on venter and throat (S. massorum lacks dark markings on venter and throat); a tibio-tarsal extension that may extend past the nostril (S. massorum tibiotarsal extension reaches between the eye and nostril); and less developed webbing on toe 4 (S. tavaratra 2 to 2.5: IV: 2 to 2.5, S. massorum 0.75 to 2: IV: 1 to 2).	en	Cramer, Abigail F., Rabibisoa, Nirhy H.

COLORATION IN PRESERVATIVE: Head dorsally and laterally reddish brown with scattered small brown spots, with larger dark brown spots concentrated on the canthus rostrum and supratympanic ridge, and a dark brown band between the eyes. Iris dark brown. Dorsum reddish brown with darker brown spots. Flanks yellowish white with faint brown spots. Arms with two dorsal broken grayish-brown transverse stripes. Legs with nine broken grayish-brown transverse stripes of uneven width. When in sitting posture, dorsal stripes on the hind limbs line up, forming three longitudinal stripes. Ventral arms and legs yellowish white with brown small spots. Throat yellowish white with lower lip bordered by grayish-brown spots. Venter yellowish white with scattered fine dark brown spots on the chest. Femoral glands brown in external view and white in internal view. COLORATION IN LIFE: Some of the reddishbrown pigment on the dorsal surface of the head and body is pale green in life. The flanks are silvery white with pale yellowish-green fine spots. The tarsal spines are white. The iris is silvery white, with dark brown radiating bands, and a pale blue iris ring. VARIATION: Morphometric variation is summarized in table 3. All specimens agree with the holotype description with the following exceptions. The presence of tubercles on the dorsum, head, and flanks range from being sparsely dispersed, as in AMNH A 167934, to frequent, as in UMMZ 212366. The supratympanic ridge is reduced and broken in AMNH A 157070 – 71, A 157073, and UMMZ 212368. The tibio- tarsal exten- sion may extend beyond the snout tip (AMNH A 157070, A 157072; UMMZ 212366 – 67). Simple dermal spines may be present on the posterior surface of the forearm (table 3). Dermal spines on the hind limb range from approximately uniform in spacing and size, as in the holotype, to alternating in size, with dermal spines generally reduced in size distally. Femoral glands 4.1 – 7.2 mm in length and 1.8 – 3.1 mm in width, separated by 2.4 to 3.5 mm, with approximately 20 to 40 granules visible in external view. Inner metatarsal tubercle range from 1.0 to 1.8 mm in length. Foot webbing variation: I 0.5 to 1 – 0.75 to 1.5 II 0 to 1 – 0.5 to 2 III 0.5 to 1.25 – 2 to 2.5 IV 2 to 2.75 – 0.75 to 1 V. Females AMNH A 157070, A 157072 – 73, A 167933, and A 167936 – 37 lack femoral glands. AMNH A 167933 is a gravid female with at least 25 visible eggs (up to 2.4 mm diameter) seen in ventral internal view. Juveniles AMNH A 157069 and UMMZ 212364 lack femoral glands, but have fore- and hind limb dermal spines present similar in number and placement to those of adults. UMMZ 212364 has very fine brown spotting on the venter. AMNH A 167933 has silver-colored longitudinal stripes on the canthus rostrum, between the eyes, and dorsolaterally on the body. The dorsum dark brown blotches and spots loosely define a postocular ‘‘ W’ ’ in UMMZ 212366 – 67. The dark spotting on the venter may extend to the throat (AMNH A 167933 and A 167936).	en	Cramer, Abigail F., Rabibisoa, Nirhy H. C., Raxworthy, Christopher J.

8C3987E12A4BFFD6E2DEFC61FEF3FDBD.taxon	discussion	REMARKS: All specimens were collected at night, between 1800 and 2300 hours, in areas by the edges of rivers and small fast-flowing streams. Animals were found on leaves, branches, and tree trunks, at heights of 0.8 – 4.0 m above the forest floor. Glaw and Vences (1997) report on four male specimens (ZFNK 59900, 59926 – 28) from 700 m elevation at Marojejy that may represent additional S. tavaratra material based on their SVL of 31 – 34 mm. Although these authors attributed these specimens to S. fimbriatus (type locality Andasibe, 500 km south of Marojejy), they also noted the small body size and differences in the call of these Marojejy specimens compared to the Andasibe S. fimbriatus.	en	Cramer, Abigail F., Rabibisoa, Nirhy H.

8C3987E12A4FFFC9E09BFDB1FD19F9F7.taxon	diagnosis	DIAGNOSIS: A large-sized Spinomantis (adult male SLV 47 – 57 mm), with type 2 femoral glands that in preservative are lighter in coloration than the surrounding skin in breeding males; vomerine teeth; END / NSD # 1.8; dorsal body pattern composed of irregular darker shaped blotches; throat white (in life and preservative); a singular subgular vocal sac in males; SVL / FT # 1.4; inner and outer metatarsal tubercles; well-developed foot webbing, with only 0.25 – 0.5 of the distal phalange free of webbing on the exterior margin of toe 3, and only 1.0 – 1.5 distal phalanges free of webbing on the internal edge of toe 4. Spinomantis nussbaumi can be distinguished from all other Spinomantis species by the following characters. Spinomantis aglavei, S. fimbriatus, S. massorum, S. tavaratra, and S. phantasticus all have hind limb dermal spines that are absent in S. nussbaumi. Spinomantis bertini is much smaller (males SVL 22 – 23 mm), and has only rudimentary webbing on the hind feet. Spinomantis elegans and S. microtis lack male femoral glands, and in addition, S. elegans lacks an outer metatarsal tubercle and S. microtis has completely webbed feet. Spinomantis guibei has distinctive markings: the ventral surface of the limbs are white with black blotches and the dorsal body has longitudinal dark lines, both of which are absent in S. nussbaumi. Spinomantis guibei also has more reduced webbing: the internal margin of toe 4 has three phalanges without webbing compared to 1 – 1.5 for S. nussbaumi. Spinomantis brunae can be distinguished by its smaller adult male body size (SVL 32 – 35 mm), reticulated dorsal body pattern, dark throat color, proportionally shorter snout (S. brunae, END / NSD. 1.8, S. nussbaumi END / NSD # 1.8), and proportionally shorter foot length (S. brunae SVL / FT $ 1.4, S. nussbaumi SVL / FT # 1.4). S. peraccae can be distinguished by its smaller adult male SLV (S. peraccae 35 – 46 mm, S. nussbaumi 47 – 57 mm; table 5) pale yellow throat color in preservative, lessdeveloped toe webbing with the exterior margin of toe 3 with 0.75 – 1.0 phalanges without webbing (S. nussbaumi 0.25 – 0.5), and femoral gland color that is the same as the surrounding skin in preservative.	en	Cramer, Abigail F., Rabibisoa, Nirhy H.

AMNH A 167947 and A 167950 have a lighter grey-brown dorsum with more defined dark brown patterning. In these specimens there is a transverse intraocular stripe that connects to a medial longitudinal stripe that extends to the dorsal pectoral region. This longitudinal stripe then divides into two longitudinal dorsolateral stripes of uneven width that terminate at the lower back (fig. 5). AMNH A 16750 also has small pale brown spots on the dorsal-posterior proximal region of each thigh. AMNH A 167948 and A 167951 have the intraocular transverse stripe and the medial stripe, and have scattered fine white spots on the posterior flanks. Spotting on the venter varies from a few small spots, as in AMNH A 167947, to extensive blotching, as in AMNH A 167948. The female and juvenile morphology is unknown.	en	Cramer, Abigail F., Rabibisoa, Nirhy H. C., Raxworthy, Christopher J.

AMNH A 167947 was found calling at the time of capture. At higher elevation at Tsaratanana, we also found specimens of S. peraccae. However, the type locality for S. peraccae is Ivohimanitra (Boulenger, 1896) in southeast Madagascar (Tanala Region), and based on the geographic variation that is evident within this complex, this suggests the potential for additional species diversity. To facilitate the diagnosis of S. nussbaumi compared to S. peraccae, we report morphometric variation within both species in table 4, which includes the holotype of S. peraccae. Additional morphological data for S. peraccae is given by Glaw and Vences (1994) and Andreone et al. (1998). IDENTIFICATION KEY TO SPINOMANTIS This key will identify Spinomantis species for all adult male specimens (the only representative material known for some species), although many characters should also identify female and juvenile specimens.	en	Cramer, Abigail F., Rabibisoa, Nirhy H.
