Othreis
abathyglypta Prout; Holloway, 1976: 36.
Diagnosis.
The forewings have a green, leaf-like pattern with an oblique black “midrib”
line running from the centre of the dorsum to the apex. The hindwings have the
black border with an entire yellow marginal zone rather than having this broken
up as in all Bornean Othreis except mionopastea Hampson,
and see also the next species.
Taxonomic
note. Bänziger (1985) established the synonymy of abathyglypta
with
sikhimensis.
Geographical
range. Indian Subregion, Thailand, Sundaland.
Habitat
preference. The species is infrequent from the lowlands to about 2000m.
Biology.
The larva of the related mainland Asian and Japanese E. tyrannus was
described by Sevastopulo (1946) and illustrated by Sugi (1987). It has the
characteristic shape and posture as described in the generic account. The colour
is a rather dull olive-green with irregular patches of white squiggles and
reticulation along the flanks, particularly well developed in a narrow saddle
across A6 within the main flexure of the abdomen when the larva is at rest.
There are large ocelli dorsolaterally on A2 and A3, that of A2 with a much wider
(but unevenly so) yellow rim. Bänziger (1987) illustrated the larva of the
related E.
okurai Okano
which is generally similar.
Sevastopulo
(1946) recorded the larva on unidentified Menispermaceae, whereas Sugi (1987)
noted it to feed in Japan on Berberis,
Mahonia
(Berberidaceae),
Akebia
and
Stauntonia
(Lardizabalaceae).
Bänziger (1987) conducted rearing experiments in Nepal and Thailand on both tyrannus and okurai.
The former accepted Berberis and Mahonia as
well as Holboellia
(Lardizabalaceae)
and, to a lesser extent, Cocculus, Sinomenium and
Tinospora
in
the Menispermaceae. The latter only accepted Holboellia,
rejecting the Berberidaceae and a range of Menispermaceae.
