Notes. Chlaenius surigaensis Jedlicka, 1935 View in CoL is a species described from the Philippines (Mindanao), up to now regarded as a synonym of C. tetragonoderus Chaudoir, 1876 View in CoL . Studying a recently collected specimen very well corresponding to this species ( Fig. 15 View Figs 15-17 ) and comparing it with a photograph of the type of this species ( Fig. 16 View Figs 15-17 ) kindly provided by Jiri Hajek, we realized that C. surigaensis View in CoL is not a synonym of C. tetragonoderus View in CoL , but it corresponds perfectly to C. maculiger View in CoL

( Fig. 17 View Figs 15-17 ); so it seems that this species is confirmed for the Philippine faune. The characters distinguishing C. maculiger from C. tetragonoderus are: sides of pronotum unevenly rounded and slightly sinuate before hind angles, disc of pronotum unevenly punctate, especially on the sides, the distance between punctures sometimes equal to 3-8 times its diameter, (in C. tetragonoderus sides of pronotum evenly rounded and not sinuate before hind angles, disc of pronotum much more evenly punctate, especially on the sides, the distance between punctures equal to 1-2 times its diameter).

151 Distribution: This species is widely distributed in the South-Eastern Pacific, being present in Australia and New Guinea. We have examined a specimen from the island of Luzon, beyond a photograph of the type of C. surigaensis , from Mindanao , extremely similar to the specimens from New Guinea and Australia that we have examined. This is the first mention of this species for the Philippines.
