03EB16372605FFDAFF0FFB36C593A412.taxon	description	N o t e s: Aphelocheirus philippinensis usually inhabits small and middle-sized, fast flowing streams (POLHEMUS & POLHEMUS 1989, and personal observations). It seems to need cold, clean water and, therefore, strong populations can only be found in areas with forest cover. Regionally, it might have become extinct already – there are no records from Central Luzon since the original description – and generally this species must be regarded as endangered. 1357 D i s t r i b u t i o n: This species is only known from Luzon: Mountain Province, Benguet, Ifugao, Laguna (USINGER 1938, POLHEMUS & POLHEMUS 1989, ZETTEL 1999); first records for Nueva Viscaya Province.	en	Zettel, H., Pangantihon, C.

03EB16372602FFD7FF0FFB43C455A5AE.taxon	description	N o t e s: The status of this taxon was discussed by ZETTEL (1999). ZETTEL (2003) described the macropterous morph. Aphelocheirus z. luzonicus is relatively common in Bicol, but rarely collected in other parts of Luzon. ZETTEL (1999) mentioned an aberrant male from Benguet (see material in this study). The brachypterous male from Nueva Viscaya is also quite different from Bicol material: It is small (body length 7.6 mm) and dorsally blackish except the yellow head and a central yellow mark on the pronotum; and it has short, obtusely rectangular embolar corners and relatively stout parameres. Possible subspecific differenciation in Luzon cannot be done before males from the type locality in Pampanga become known. Consequently, all Luzon specimens are presently summarized under one subspecific taxon, luzonicus. 1358 D i s t r i b u t i o n: Known from Luzon: Pampanga, Cavite, Camarines, Norte, Camarines Sur, Albay, Sorsogon; and from Catanduanes (POLHEMUS & POLHEMUS 1988, ZETTEL 1999, 2003); first records for Mountain Province, Benguet, Cagayan, and Nueva Viscaya Provinces, all in Luzon.

We especially thank Prof. Dr. Emelina H. Mandia and Prof. Dr. H. Freitag (De La Salle University, Manila) for organizing the field work in Mindoro with underlying permissions from DENR and other authorities involved and for providing the habitat picture and map of Lake Naujan (Figs 12, 13).

Seyfert (Vienna). We also thank H. Bruckner (Vienna) for help with producing Figure 1, and Prof. Dr. Robert W. Sites (University of Missouri) for correction of the English text. Zusammenfassung Eine neue Grundwanzenart, Aphelocheirus (s. str.) freitagi nov. sp., wird von der Insel Mindoro im Westen der Philippinen beschrieben. Die neue Art gehört in die vom westlichen Himalaja ostwärts bis nach Borneo und den Philippinen verbreitete A. minor - Artengruppe und ist mit zwei weiteren philippinischen Endemiten, A. palawanensis POLHEMUS & POLHEMUS 1989 und A. zamboanga POLHEMUS & POLHEMUS 1989, nahe verwandt. Obwohl Mindoro seit 1992 mehrfach hinsichtlich seiner Wasserwanzenfauna untersucht worden ist, handelt es sich um den Erstfund von Aphelocheiridae auf dieser Insel. Neufunde von vier weiteren Aphelocheirus - Arten von der Insel Luzon werden aufgelistet.	en	Zettel, H., Pangantihon, C. V.
