FIGURE 3 in A new dichromatic species of Myotis (Chiroptera: Vespertilionidae) from the Nimba Mountains, Guinea

FIGURE 3. Portrait of Myotis nimbaensis (AMNH 279589, holotype). A, View of right side of upper body and head showing the pale ventral fur and bright orange fur on the head and the ruff around the neck; also note the brown color of the thumb. B, Anterior view of the left ear showing the pale orange-brown color of the pinna, strong distal emargination, and rounded pinna tip. C, Anterior view of right ear showing the ridges in the pinna and the relative length of the lanceolate tragus, which is slightly less than half the length of the pinna. D, Close-up view of the right side of the head showing the pale skin visible through the fur around eye, mouth, and on the rostrum; also note the strongly tricolored fur on the top of the head.

FIGURE 6. Uropatagium, foot, calcar, and flight membrane attachments in Myotis nimbaensis (AMNH 279589, holotype). A, Dorsal side of the uropatagium showing orangish brown skin with orange fur on the proximal 1/3 of the surface of the membrane. B, Ventral side of uropatagium showing pale cream-colored fur on proximal 1/5 of ventral membrane surface; this fur continues across the femur onto the proximal plagiopatagium in a narrow strip that does not extend past the knee. C, Dorsal view of distal leg, foot, calcar, and associated flight membranes. Note that the wing membrane (on right of the foot) attaches to the foot at the base of the first toe, and the calcar (on the left of the foot) is more than twice the length of the hind foot. D, Close-up of the dorsal surface of the foot showing sparse, long brown hairs on each toe. E, Close-up of the ventral side of foot and toes showing dark brown coloration. F, Ventral view of the hind leg and foot showing the relatively small foot size (foot length = 2/5 of tibia length) and the patterning of black membrane pigmentation near the leg and foot.

FIGURE 5. Coloration of the wing membranes in Myotis nimbaensis (AMNH 279589, holotype). A, Dorsal surface of the wing showing the dichromatic black and orange skin coloration. The plagiopatagium and dactylopagial membranes are mostly black with thin orange bands along the metacarpals, phalanges, and forearm; the black pigmentation also extends nearly to the body wall in the area between the forearm and the hind leg. The propatagium is pale orange. B, Dorsal surface of the anterior and proximal portion of the wing showing the patterning of the black pigmentation near the body. C, Dorsal surface of the distal wing showing the brown thumb and orange (not black) pigmentation of the membrane between digits II and III.

FIGURE 1. Relief map with satellite imagery overlaid showing the capture locations of the Myotis nimbaensis holotype (red triangle: captured 26 January 2018; red circle: collected 2 February 2018) and other sites where this species was likely detected with acoustic monitoring at entrances of underground sites (yellow squares). The mining concession footprint is shown as the unshaded area within the Nimba Mountains Strict Nature Reserve and Mount Nimba World Heritage Site (identical boundaries) that are overlaid by light green shading. Dominant habitat types are visible as different textures from the satellite imagery showing how gallery forests occur along steep canyons surrounded by savanna at higher elevations. Roads and trails in the mining concession are also visible as light brown features. Location of the Nimba Mountains in relation to Guinea, Liberia and Côte d'Ivoire is shown in the inset.

FIGURE 4. Fur color and banding in Myotis nimbaensis (AMNH 279589, holotype). A, View of the dorsal fur showing the overall bright orange coloration; creamy white bands on the hairs proximal to the bright orange fur tips are visible on the lower right near the leg where the fur has been somewhat disturbed. B, Close-up of dorsal fur over the lower back showing tricolored fur in a spot on the center left where the fur has been slightly teased apart; where the fur is undisturbed, the banding of individual hairs is not visible. C, dorsal fur over lower back clearly showing the tricolored banding in an area where the fur has been separated by blowing. D, Ventral fur over torso showing overall paler coloration than dorsal fur, and tricolored banding of the hairs with less orange at the tips. E, Ventral fur over left side of the thorax showing bicolored banding (lack of a black basal band) near the wing membrane.
