REMARKS
Colura inuii
is very similar to the widespread Indopacific
C. conica
(see
Zhu & So 2001
) but in the latter species, the sac always has a crested, toothed apiculus whereas in
C. inuii
, it

does not occur. The perianth keels of
C. conica
have 1-3 celled sharp teeth at the end of the wings (Jovet-Ast 1953, fig. 51: 1-3) whereas in
C. inuii
,
the perianth keels are often strongly mamillose but teeth are never produced. Moreover, the oil bodies are homogenous (smooth externally, rarely segmented into indistinct granules) in
C. inuii
while granular (faintly rough externally) in
C. conica
(seeYang
et al.
2013: figs
2g
, 3e). Furthermore, both species can be distinguished by the presence of 18-20 median valve cells and 17-19 surrounding hyaline cells in
C. inuii
while 13-17 and
15-16 in
C. conica
.

Malaysia
, which record in Peninsular
Malaysia
represents its southernmost locality, extending to the Malesian region. The species usually grows on living leaves, rarely on bark and can be considered, as typical epiphyll; in
Malaysia
it was found on living and dry fallen leaves in a lowland dipterocarp forest and also in montane forest, above
