Distribution

Aphelocheirus freitagi Zettel and Pangantihon, 2010 (see Zettel and Pangantihon 2010) (Fig. 4 D) is endemic to Mindoro and was previously only known from its type locality, Malayas River in Victoria, Oriental Mindoro ( Zettel and Pangantihon 2010). Here we present the first records from Baco and Roxas (Fig. 5 ).

Taxon discussion

Habitat

Aphelocheirus species Westwood, 1883 thrives in rather large, fast flowing rivers (Fig. 1 D; Fig. 2 A and B) with substrates consisting of a mixture of gravel and sand. The species is a typical benthic bottom dweller.
