Systematics of species referred to the genus Angiostrongylus

Based on morphological criteria of the male bursa, angiostrongylid nematodes often placed in the genus Angiostrongylus Kamensky (1905) were found to be heterogeneous, comprising species which are relegated to 5 distinct genera: Angiostrongylus Kamensky, 1905 (syn. Haemostrongylus Railliet and Henry, 1907); Parastrongylus Baylis, 1928 (syn. Pulmonema Chen, 1935, Rattostrongylus Schulz, 1951, Morerastrongylus Chabaud, 1972, Chabaudistrongylus Kontrimavichus and Delyamure, 1979); Angiocaulus Schulz, Orlov and Kutass, 1933; Gallegostrongylus Mas-Coma, 1977 (syn. Thaistrongylus Ohbayashi, Kamiya and Bhaibulaya, 1979 n. syn); and Stefanskostrongylus Drozdz, 1970. These genera all contain species located primarily in specific host groups: Angiostrongylus in carnivores; Parastrongylus in rodents (Muridae), Angiocaulus in mustelids; Rodentocaulus in rodents (Cricetinae), Gallegostrongylus in rodents (Muridae), and Stefanskostrongylus in insectivores. Species in each genus include: Angiostrongylus (A. vasorum, A. raillieti, A. chabaudi); Parastrongylus (P. tateronae, P. cantonensis, P. mackerrasae, P. sandarsae, P. sciuri, P. petrowi n. comb., P. dujardini, P. schmidti, P. costaricensis n. comb., P. malaysiensis n. comb., P. ryjikovi n. comb., P. siamensis n. comb.); Angiocaulus (A. gubernaculatus, A. ten n. comb., A. sp. Caballero, 1951); Rodentocaulus (R. ondatrae) and Gallegostrongylus (G. ibicensis, G. andersoni, G. harinasutai n. comb.). Angiostrongylus pulmonalis is likely similar to Stefanskostrongylus soricis and is transferred to this genus. Angiostrongylus minutus is removed to Stefanskostrongylus.
