Dr. Velasquez's contributions to science include thirty-two new species and one new genus of digenetic trematodes from Philippine food fishes, two from birds and five from mammals; nine life cycles of trematodes of the family Transversotrematidae, Echinostromatidae, Notocotylidae (2), Plagiorchidae, Heterophyidae (2), Microphallidae and Philophtalmidae. In addition, two new species of nematodes from Philippine fishes and a new species of Capillaria from the intestine of man. Also, a new species of parasitic copepod in Glossogobius giurus (Goby). Most of these works are published in international journals and cited in a number of journals abroad.
