Two females of the least epauletted fruit bat were caught at two sites within the
Dire Dawa
town. According to data by
Claessen and De Vree (1991)
, the records from
Dire Dawa
area only slightly shift the known limits of the distribution range of this species to the north-east. In the surrounding areas of the eastern edge of the Chercher Mountains,
E. minimus
represents a regularly encountered fruit bat species; specimens were collected in the areas some
50
–
80 km
south-east of
Dire Dawa
, at
Harar
, Errer Valley, and Babille (
Claessen and De Vree 1991
;
Lavrenchenko et al. 2010
); Bahadu, the
type
locality of
E. minimus
, lies only some
145 km
WNW of
Dire Dawa
.
External dimensions of the specimens collected in
Dire Dawa
are as follows (DDW03/ DDW18): weight 36/
38 g
, head and body length 95/
109 mm
, forearm length 60/
65 mm
, ear length 16/
19 mm
; skull dimensions (DDW03): largest skull length
31.12 mm
, condylobasal length
29.86 mm
, zygomatic width
17.98 mm
, neurocranium width
12.96 mm
, neurocranium height
9.81 mm
, length of upper tooth-row
10.89 mm
. The species identification based on the craniodental data comparison conforms to those given by
Claessen and De Vree (1991
, p. 219); the result of discriminant function counted from three cranial measurements is 47.5. In
E. minimus
this value should be below 116, while higher values indicate
E. labiatus
(Temminck, 1837)
, which, however, is not known to occur in eastern
Ethiopia
or in
Somalia
(
Claessen and De Vree 1991
;
Lanza et al. 2015
).
