Rl. Palma, A NEW SYNONYMY AND NEW RECORDS OF QUADRACEPS (INSECTA, PHTHIRAPTERA, PHILOPTERIDAE) FROM THE GALAPAGOS-ISLANDS, New Zealand journal of zoology, 22(2), 1995, pp. 217-222
Nirmus paludicola Kellogg and Kuwana, 1902, now Quadraceps paludicola
(Kellogg and Kuwana, 1902), is proposed as a senior synonym of Quadrac
eps ernstmayri Timmermann, 1952 (new synonymy). The host-louse associa
tion between Q. paludicola and its type host, Butorides sundevalli (Re
ichenow, 1877), is discussed and deduced to be erroneous. The swallow-
tailed gull, Creagrus furcatus (Neboux, 1842), from the Galapagos Isla
nds is regarded as the regular host for Q. paludicola and is also the
type host of Q. ernstmayri. Eight further species and subspecies of Qu
adraceps are reported from the Galapagos Islands for the first time, a
nd are included in an annotated checklist together with all Quadraceps
taxa previously known from those islands.
