Metriorrhynchus philippinensis Waterhouse, 1879

Differential diagnosis. Very similar to the larva of Metriorrhynchus thoracicus . The shape of pronotal, lateral and tergal abdominal processes and the very complex branched urogomphi (figure 107) are as in M. thoracicus and M. lobatus (Sulawesi) . M. philippinensis differs in the following characters: meso- and metanotum only at lateral margins dark brown to black, yellow in middle, lateral processes T2–T3 and A1–A6 concolourous black and in presence of four processes at posterior margin of tergum A6. The presence of four processes was found in M. lobatus (Sulawesi) , which may be distinguished by the white abdominal segment A3.

Measurements. BL 12.3 mm, PW 2.1 mm, PL 1.75 mm.

Material examined. One medium instar larva. Philippines, Mindanao, 30 km W of Maramag, Bagong Silang vill., 1600 m, v.1996, Bolm. lgt. ( LMBC) .

Remark. The identification of the larva of M. philippinensis is based on its similarity to Metriorrhynchus larvae from Sulawesi and the fact that M. philippinensis is the only member of the genus in the Philippines having a large body. The adults of M. philippinensis were collected in the same area as larva.
