Mindoro, 12 mm
Need confirmation that this is Prothema angulifera Aurv, 1916.



Just acquired this specimen from Mindoro. Again, very close to anulifera.

Not simple : here the original description & drawing..., here pictures from the forum, but without any holotype, I am not sure to know what is a true Prothema leucaspis Chevrolat, 1863 ( the other philippines species).

Original description


Chevrolat wrote that first longitudinal band is almost touching the second one (oblique).-> so, they are separated.
So, I think your specimen and specimens from the forum gallery are Prothema leucaspis Chevrolat, 1863
The drawing of P.angulifera shows a complete band, like a semicircle, no ?

I've added a pic of one of the many lucaspis forms I have seen from the Philippines. The basal marking are quite different in the two and which is which is why I asked for confirmation. Occasionally I see a lucaspis with the basal marking broken into two pieces but never angled as shown in my first pic and those from Borneo.

Sorry, but I am unable to say what are P. leuscapis and P.angulifera with only descriptions. I wonder if they are really different species...

None of the specimens above is P. angulifera, which - most probably - occurs on Borneo only (I have never seen any similar specimen from Mindanao; specimens from continental Malaysia or other Indoesian islands most probably belong to different sub/species).

I have not seen the type of P. leucaspis (there is on or two more species in the Philippines).

Would sure be nice to put this to rest as to what is angulifera. I've included another picture of a specimen form Borneo which may be anulifera and it is very similar to my Mindoro specimen. I also have one from the Negros that matches it.

I replace the one I had with your link, a much better picture, in my photo catalog of Philippine longhorns (for comparison with my material). Did not even realize I did it.
One of the perils of getting old. Bear with me.

Prothema anguliferum Aurivillius, 1916 has been described from Borneo Island. Later, Hayashi(1987) added north Luzon (Philippines) to the distribution. Could it be a mistake ?

Does somebody have in collection a Prothema anguliferum Aurivillius, 1916 from Borneo ?

I have a couple from Borneo and 1 from Sumatra.

This one is from Sabah. I don't recall if the males and females are sexually dimorphic like some species in the genus. I will check later.

I will throw this in. Is it possible that barring sexual dimorphism, we could be dealing with two species from the Philippine area, one not being described?
