Distribution

Rheumatogonus luzonicus (Kirkaldy, 1909) (see Kirkaldy 1909) (Fig. 9 D) is endemic to the Philippines and has been recorded from Luzon, Mindanao, Mindoro ( Freitag and Pangantihon 2010, see Fig. 8 for additional records), Negros and Panay ( Chen and Nieser 2002). Some unpublished records from Catanduanes, Marinduque, Sibuyan, Ticao, Cebu, Samar, Leyte, Mindanao, Siquijor and Poro have also been recognised belonging to this species ( Zettel 2014).

Taxon discussion

For identification, refer to Chen and Nieser (2002).

Habitat

The specimens were collected from the surface and littoral of calm and moderately fast flowing creeks and medium-sized rivers (Fig. 1 A, B). In general, Rheumatogonus Kirkaldy, 1909 species inhabit mountain streams, creeks and waterfalls in the Oriental Region, specifically the shaded, steady slow-lotic sections of such watercourses ( Chen et al. 2005).
