The new Metapocyrtus species from Mindanao reproduced from the paper

I was rather surprised when I received an email from Hiraku Yoshitake where he sent me his latest paper: A New Species of the Subgenus Artapocyrtus of the Genus Metapocyrtus (Coleoptera: Curculionidae: Entiminae) from Mindanao, the Philippines.

What I know is that the last time a new species of Metapocyrtus and even with Pachyrhynchini in general was described by Schultze in 1934. This can also be confirmed in Yap 2008.

Now, Yoshitake has described Metapocyrtus sakaii from Surigao del Sur, Mindanao from the private collection of Kaoru Sakai. He says that the said species is different from its allied species by the presence of the conical projection on the ventral part of the rostrum for both sexes. The holotype is deposited in the NIAES type collection.

Looking at my beetle photo RAW files that I’ve taken months ago, I processed seven which I then updated in this site. All are Scarabaeidae of which four are Cetoniinae, one Valginae and two Melolonthinae. There are still many photos to be processed but due to time constraints and difficulty of doing it, will do this some other time.

I have now 1,266 photos in this site.

The new paper on the Hawaiian, Oriental, Australasian and Japanese Parandrinae

The subfamily Parandrinae is one of the most challenging Cerambycidae groups when it comes to identification. Prior to the work of Santos-Silva, Heffern and Matsuda, Philippine Parandrinae was lumped under a single species: Parandra janus BATES 1875.

Last July 2010, Insecta Mundi finally published the long awaited paper of the three authors: Revision of Hawaiian, Australasian, Oriental, and Japanese Parandrinae (Coleoptera, Cerambycidae) wherein they took on the gargantuan task of putting order into this very complex group. I was asked to contribute some specimens from my collection plus those from my friend Eduard Vives. The result? Seven new species of Parandrinae for the Philippines alone!

Check out my updated Parandrinae checklist. Now, I’m in the process of identifying the rest of my specimens in my collection.

Metalloleptura prasina HELLER 1913

It’s quite mind boggling that the Philippines, when compared with Borneo, mainland Southeast Asia and Taiwan has a dismal record number of longhorns from the subfamily Lepturinae. To date, two tribes are represented only with a total of eight species: Lepturini, with seven species from six genera and one species of Rhamnusiini as outlined in the checklist.

This is in light of the high endemicity levels in the country with many interesting islands. In my collection alone, all from Mindanao, I only have five species of which one, Heffernia filipina VIVES 2005 (tribe Rhamnusiini) is a new species. These were all high altitude cerambycids, which I consider all Lepturinae to be.

In the case of Palawan, I’m not so sure if there are listed Lepturinae species either endemic or not and this is quite a pity that this island is a part of Sundaland, an extension of the Bornean fauna where there are lots of these.

Maybe a good explanation is this: there is a lack of serious collecting in the higher elevations of the country. Palawan may hold several new species or records. Mindanao and Luzon should also be sampled as well as the major islands in between. If this is done, perhaps, we can push the number higher.

Pachyrhynchus samarensis (?) on tree bark

Trail leading to the falls

I was invited by my friend, Raegan, the world authority on Philippine Odonata to a brief trip to Epol Waterfalls in Marilog District, Davao City a few weeks ago. A two hour bus ride from the city, the area is already disturbed with secondary stands of forest. It is also a popular place for day trippers visiting the cascade.

I’m not so hopeful of getting new species on the families that I collect but it is always a good thing to go out with like minded persons and best of all, there was no competition as he was concentrating only on Odonata while I focus on Coleoptera. Of course, having been assigned in Davao City for a total of two years before, I’ve been in the area and, more or less, know what to find.

Metapocyrtus sp.

I was able to collect two species of Metapocyrtus (subgenus Metapocyrtus and subgenus Trachycyrtus) but what surprised me most was the presence of Pachyrhynchus (probably samarensis) all found on tree bark.

There were three species of tiger beetles, Cicindelidae: 2 species of Therates and one Neocollyris. Curiously, even with the presence of streams in shaded areas, there were no Thopeutica.

I only saw one small Melolonthinae but it flew away. One longhorn, Cerambycidae, Apomecycini was collected. No buprestids.
