Guimarães Abstract Four new species of Forficuloecus Conci, 1941 are described from birds from the South Pacific: F. emersoni, type host Alisterus chloropterus (Ramsay); F. pilgrimi, type host Cyanorhamphus novaezelandiae chathamensis Oliver; F. greeni, type host Neophema chrysostoma (Kuhl), and F. palmai, type host Barnardius zonarius (Shaw). Guimarães (1974) revalidated Forficuloecus (then in the synonymy of Echinophilopterus) to contain F. forficula (Piaget, 1871) and F. meinerízhageni, a new species. The four species described below closely fit Guimarães' generic diagnosis. Forficuloecus meinertzhagenl Guimarães, 1974 (Figs. 1, 9) Forficuloecus meinerízhageni Guimarães, 1974; 177 Specimens examined: A couple collected on Nestor m. meridionalis, from Paterson Creek, Canterbury, New Zealand, and a couple collected on Nestor notabilis, from New Zealand (ali from the Pilgrim Collection). Guimarães (1974) noted that a couple of Forficuloecus found on Nestor notabilis differed from typical meinerízhageni in the shape of the anterior dorsal plate and in the number of setae oh the ventral side of the terminal segment of the male. The specimens now examined show that the supposed differences may be confidently said to be non-existent. The anterior dorsal plate was incorrectly figured by Guimarães in 1974. Figure l in this paper, based on a specimen from Nestor m. meridionalis, shows the actual shape of the strueture in Forficuloecus meinerízhageni, both in specimens from the type host and from Nestor notabilis. The number of setae on either side of the ventral region of the terminal segment of the male is praclically the same in both cases, i.e., 6/9 in the lice from meridionalis and 10/11 on those from notabilis.

Forficuloecus emersoni, sp.n. (Figs. 2, 6, 10, 14) Type host: Alisterus chloropterus, probably subspecies chloropterus (Ramsay). Specimens examined: 1 male and 1 female, from Bulolo, New Guinea, H. Clissold col., 3 March, 1962. Similar to Forficuloecus meinertzhageni. However, the pre-antennal region is longer in both sexes, especially the area in front of the dorsal pre-antennal suture; thus the anterior dorsal plate greatly differs in shape in the two species (Figs. 1 and 2). In the specimens of meinertzhageni studied in 1974, the number of setae on each side of the terminal segment of males varied from 6 to 9; in the specimen now at hand there are 9. In emersoni there are only 4/5. The main differences between the two species are found in the genitalia of both sexes. The apodeme on the distai end of the mesosome is shorter in the new species; the mesosome is differently shaped and does not show the gutterlike structure on the anterior region (fig. 6). The setae on the female genitalia (fig. 14) are not as uniformly disíributed as in meinertzhageni.

Johns col., 13.Ü.1969; 2 females and 2 teneral, same data as above, Buller col., 1891. Very similar to the preceding species. The region in front of the pre- -antennal suture is shorter, although not as much as in meinertzhageni. The dorsal anterior plate (Fig. 3) is also shorter, wlth latero-posterior margins almost straight, ending in a fine point. There are 3 to 8 setae on each side of the ventral region of the terminal segment of the male. The major differences among the three species, shown by the male genitalia, may be seen in figs. 6, 7 and 8. There is a small difference in the numíber of tergal setae as well as in the shape of the genitalia in the females (figs. 14 to 17). However, since only one female of emersoni is available, it is impossible to decide whether such differences are real or merely the result of individual variation, or even artifacts of preparation.

(Figs. 5, 13, 17, 20) Type host: Barnadius zonarius (Shaw) Specimens examined: 3 females collected on the type host, from Aus- trália, by J.R, Jackson. Although only females of this form are available, I have no doubts about its distinctiveness, so pronounced are the differences between it and the other species of the genus. As in the preceding species, only m.t.s. 4 is long. The tergo-central and sternal setae are more numerous than in the other species. The tergo-centrals, although a little shorter than the tergo-laterals, stand on a continuous row with them on segments III to VI; setae of latero-posterior corners starting from segment III. The female genitalia resemble (fig. 17) those of F. forficula (Piaget), i.e., they show two contiguous median structures in the shape of two thick commas, with the points turned in- and backwards. The general outline is very broad, but this may be due to the process of mounting. Vol. 36 (5). 1985 47 s \ 18 19 F. greeni: Fig. 18, male; fig. 19, female.

Pilgrim, of the Department of Zoology, University of Canterbury, Christchurch, New Zealand; a Paratype female in the Collection of the Museu de Zoologia da Universidade de São Paulo. The specimen identified by Piaget (1871) as Docophorus forficula and considered by Guimarães (1974) as a Forficuloecus, may belong to the present species, Its host is Platycercus baueri, considered already by Salvadori (1891) as a synonym of Barnardius zonarius; Piaget notes that the "forficula" from this host had a larger number of abdominal setae. The name honors Dr. Ricardo L. Palma, National Museum, Wellington, New Zealand. Acknowledgments Thanks are due to Drs. Theresa Clay (British Museum, Natural History), R.L.C. Pilgrim (University of Canterbury, Christchurch), R.L. Palma (National Museum, Wellington) and K.C. Emerson (Sanibel, Florida), for the loan of specimens.
