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? |
