This Male is the first record in Borneo. |
Agriocnemis genus has three tiny species widely found in drains, ponds and
swamps from the lowlands.
Agriocnemis femina is the most common in Sabah. The
immature male is green and orange but on maturity it becomes dark with heavy
pruinescence on the head and synthorax. The labrum (upper lip) is shining
metallic-purple. The male appendages are distinctive and unusual, with the lower
pair very long in relation to the upper pair. Females may be olive green or red
and vary in the markings on the thorax. They are almost always found in open
country and are often reproductively active late in the day, females ceasing
oviposition only at sunset.
Agriocnemis pygmaea is distinguished by the male anal
appendages, (quite unlike those oi femina), and by shape of the female prothorax.
Agriocnemis pygmaea is probably widespread. It is very like immature Agriocnemis
femina in color.
Agriocnemis minima seems to be confined to the south and
east of Borneo and is found in swamp forest.
