Danum Valley - July 2013

[Psyche]

Last of my Lycaenidae.

LD15) Nacaduba species from this year.
LD16) Nacaduba sp. from 2010. This was id'd as N. berenice at the time.

The two appear different, particularly in the shape of the forewing submarginal spots in spaces 1b and 2, which are rectangular in this years photo, and more oval in that of 2010. As far as I can see, only N. berenice, kurava and the endemic normani are found in Sabah as far as Six-lines go.

LD17) I thought this was Celastrina lavendularis, but I could not see that it is found in Borneo when trying to find the ssp. There is Celastrina philippina philippina, though and two Acytolepis species.

LD15 should be Nacaduba berenice.
The marginal spots are flat-sided. The submarginal spots somewhat resembles beroe , but dark striae in FW band strong & base not distinctly darkened.
A bit of the dull lavender upperside can be seen.

LD16 should be Nacaduba normani.Correction: ID doubtful as N. calauria is also found in Borneo.
Both series of spots very dark; FW marginal spots large & bulging; HW marginal spot 3 rounded.
Federick posted a couple from his Kinabalu trips which I ID'ed as N. calauria not realising N. calauria is not recorded from Borneo.
N. calauria range from India thru Sumatra, Java to Sulawesi & Ambon.
It is replaced in Borneo by N. normani which has also found its way into Sulawesi.
The other 6-line blues, berenice, kurava, & beroe can be discounted.

LD17 should be Acytolepis ripte.
There is a small white-edged triangular spot at the base of HW space 7 (none in Celastrina) ;antennal tip black (white in Celastrina ).
The FW cell has a ill-defined white-edged rectangular spot (perspective-distorted) with a black smudge below (FW cell clean in puspa).
LC's perfect example from Meliau.

Celastrina lavendularis, widespread from India to Papua is replaced in Borneo by C. philippina (probably 2 ssp overlapping in the Philippines.).
Main difference on upperside. Only underside difference seen is lower end of HW cellend bar close to postdiscal spot 2 in lavendularis.
