8 simple ridges, 4+0+4 unknown narrow interfemoral membrane, calcar absent Micropteropus 49–64 very short yes shoulders – long white hair 6 prominent ridges (1^st undivided, remainder divided by prominent medial gap), followed by variable number of narrow serrated ridges, 1+5+2–4 unknown Myonycteris 66–88 short no throat – ruff of long sticky hair usually 8 or 9 ridges, 3+4+2 inserts on 2nd toe metacarpal and first phalanx of 5^th digit = (or >) forearm length Epomophorus 60–95 absent yes shoulders – long white hair 6 thin ridges, typically 4+2+0, except E. dobsonii which has 5 thick ridges and 3–4 thin ridges (see genus matrix) inserts on 2^nd toe face as long as braincase Epomops 80–104 absent yes shoulders – long white hair 3 thick undivided and 5–8 thin ridges, 3+0+5–8 inserts on 2^nd toe face much shorter than braincase Rousettus 86–106 short no two restricted glandular areas with stiffened hairs on sides of neck typically 8 ridges, 4+3+1 inserts on 1^st toe or between 1^st and 2^nd metacarpal and first phalanx of 5^th digit much shorter than forearm length Stenonycteris* 85–95 short no two restricted glandular areas with stiffened hairs on sides of neck 8 ridges, 4+3+1 inserts on 1^st toe or between 1^st and 2^nd metacarpal and first phalanx of 5^th digit much shorter than forearm length Eidolon 110–130 short (∼15 mm) no glandular hairs on neck 8–11 ridges, 4+3+1–4 or 3+4+1–4 inserts on 1^st toe; naked wing dorsal fur restricted to narrow band Hypsignathus 114–134 absent yes absent 10–11 ridges, the first 5 are thick while the remainder are thin unknown large, swollen muzzle, especially pronounced in males

¹ Palatal formula indicates, from front to back, three groups: undivided ridges, divided ridges and thin serrated ridges near the posterior end of the palate^* Stenonycteris can be readily distinguished from Rousettus by its comparatively long fur
