Sonan (1938a)
specified just one male specimen when he described
Tagiades menaka hainana
, thus it represents the
holotype
of the taxon. The unique
type
(
holotype
) of the taxon was found in TARI (
Fig. 37–39
), and the specimen conforms to the original description and associated figure in
Sonan (1938a)
although the collecting year was “1908” in the original description but “1930” on the label.
Evans (1949)
intended to list
hainana
as a synonym of
Tagiades menaka menaka
(Moore, 1865)
, but the name
hainana
was in the index of his catalogue and not in the text. The characteristics of the
holotype
, however, do not agree with those of
T. menaka
. Instead, the
holotype
possesses diagnostic characters of
T. japetus
(Stoll, 1782)
defined by
Evans (1949)
and
Tsukiyama (1980)
as it has no hyaline spot in front of spots at the end of discoidal cell and a prominent hyaline spot in cell M3 and Cu1 of the forewing (
Fig. 37–38
). The wing markings of the specimen are generally similar to those of the wet season form of
T. j. ravi
Moore, 1865, but differ from it by possessing a white hindwing fringe instead of brown. Although it is difficult to accept the fact that this rather common skipper is represented by a single specimen, there is no specific evidence that it was mislabelled. Thus the name
hainana
may be used as the valid subspecific name for populations of
T. japetus
(
status revised
) inhabiting the island pending further research.
