Undetermined species
A number of further species are represented by limited material as
follows:
Idaea sp. A.
(slides 17802, 18502; )
These two males (7mm) resemble smaller, greyer more strongly marked
versions of sakuraii. However, the genitalia are characterised by
an unusual flanged and irregular costal margin to the valve. The setae at
the apex of the gnathus are robust. The aedeagus has no cornuti: the two
small spines displaced to the base of the right valve in the photograph
may be associated with the anellus, homologous with those of sakuraii. There
is a well-developed pouch on the second abdominal sternite. One is from
Semengok, a lowland locality near Kuching, and the other is from wet heath
forest (kerangas) near the Melinau Gorge, taken during the Mulu survey.
Idaea sp. B.
(slide 18535; )
A female (8mm), medium grey with diffuse fasciation and small blackish
discal spots, has unusual genitalia with a strong appendix bursae
consisting of a large, narrow tube with a small spherical diverticulum
subapically. The bursa itself is approximately the same length, elongate,
slightly constricted centrally and with a basal zone of scobination. The
specimen was taken at about 600m on G. Trus Madi in Sabah.
