Lepturinae and Vesperinae, subfamililies of Cerambycidae are a bit understudied in the country. Compared with neighboring areas like Taiwan, Borneo and mainland Southeast Asia where a good number of species have been collected and described, Philippine species from these two subfamilies are so poorly known.
From correspondence with Eduard Vives who drew up a provisional checklist of Cerambycidae, there are only 9 species of Lepturinae belonging to 8 genera and a single species, Philus lumawigi, under Vesperinae. Its a bit puzzling that for a country so rich in fauna, these are the only ones that, so far, are known.
Below are the species of Lepturinae and Vesperinae known in the country:
Philus lumawigi HUDEPOHL, 1990
Asilaris quadrifasciatus SCHWARZER, 1931
Ephies philippinensis SCHWARZER, 1931
Ephies hefferni HAYASHI & NARA, 1996
Metalloleptura prasina HELLER, 1913
Stenoleptura (Philippinostrangalia) apoensis OHBAYASHI & SATO, 1974
Elacomia collaris HELLER, 1916
Leptostrangalia angustolineata GRESSITT, 1935
Heffernia filipina VIVES, 2005
Trypogeus cabigasi VIVES, 2005
Again, there is a need to have a systematic field collection that should be done specifically for these group of longhorns. I’m not really sure if these are found in the lowlands but in my experience collecting in Bukidnon, these are rather abundant during the months of April to May in treetops at rather high altitudes (about 3,000 ft asl). I have also collected a female Stenoleptura apoensis SATO & OHBAYASHI, 1974 on June 2001 hovering around the dried branches of a fallen tree at a forest clearing. For Versperinae, I’ve read a paper before that indicates that these are attracted to lights during the night.
