At last, the paper of my friend Eduard came out and it is the second installment in his study of Philippine Cerambycidae and entitled Cerambicidos nuevos o interesantes de Filipinas (Part II) (Coleoptera, Cerambycidae). I’ve been waiting this second part as I have contributed many specimens here. These were either new records for the Philippines or new species with some named after me and one on my mother.
This issue from Magellanes features 32 longhorns including 17 new species of which I have contributed 10, 7 of which are new.
The genus Engertia DALLA TORRE 1912 (Melolonthinae, Scarabaeidae) consists of five described species from Sri Lanka to New Guinea. In the Philippines, one is described while two are new and undescribed species. As listed in Denis Keith’s paper Reflexions sur le Genre Engertia et description d’une nouvelle espece des Philippines (Col. Scarabaeoidea Melolonthidae) (Lambillionea, 2006), the genus has the following species:
- maculosa BRENSKE 1896 (Sri Lanka)
- amboinae BRENSKE 1897 (Moluccas)
- papuana MOSER 1913 (New Guinea)
- setifera MOSER 1913 (Moluccas)
- lii KEITH 2006 (Philippines – Leyte and Palawan Islands)
Engertia lii KEITH 2006
This species also occurs in the island of Mindanao where my specimen was collected. Judging from the localities where this species occur, it might be found nationwide as Leyte and Palawan represents two different biogeographical regions (faunal regions) with the latter considered part of Sundaland.
The light colored pubescent markings on the pronotum and elytra are quite delicate and are easily rubbed off and I have collected other specimens where the pronotum is almost bare.
Engertia sp.
According to Keith, the two specimens from Luzon and Mindanao, respectively, shown here are still undescribed. The author might publish his study later once additional specimens are available.
I have added new scarabaeidae photos in this site, ten in fact including the aedeagi.
My Xyoltrupes gideon philippinensis ENDROEDI 1957 (right) has been with me for quite a while but haven’t taken a photo of it. This specimen from Luzon showing the dorsal and lateral views was given to me by a friend who got many specimens from Bataan.
Papuana lansbergei SCHAUFUSS 1887 is a small dynastid beetle from Mindanao that I’ve got a few years ago. It’s rather uncommon and is usually collected during night especially with lights. I added two views of the same aedeagus of the male to illustrate it. In most scarabs, this part is one key element in identifying it down to species level. Especially helpful in a number of Protaetia and Parastasia genera and others from the subfamilies Melolonthinae and Rutelinae.
The third dynastid beetle photos that I’ve added is the lateral and head view of Oryctes gnu MOHNIKE 1874, a bigger, more robust and rarer species compared to it’s relative, O. rhinocerus LINNAEUS 1758. This was collected in Mindanao.
I’ve added three images of Glycyphana (Caloglycyphana) rubromarginata MOHNIKE 1873 consisting of a female, male and its aedeagus (male sexual organ).
Lastly, a Dasyvalgus sp. completes the list. The subfamily Valgiinae in the Philippines is represented with only a few species of which this genus comprises the biggest, consisting of around eight small species less than a centimeter long. I’m not sure what this is but since it was collected in Busuanga it might probably be D. palawanus. But I still have to check the literature to confirm this one.
Additional photos of Cerambycid beetles were added to this site consisting of four species:
- male, normal form, Schmidtiana gertrudis HUDEPOHL 1983
- female, Batocera numitor NEWMAN 1842
- female, Abryna (Faustabryna) metallica BREUNING 1938, and
- another Callimetopus sp.
Well, no new species but these provides how the different sexes would look like. Check out the individual pages.
