NO. 3658 MALLOPHAGA—ELBEL 51 
Summary 
Amblyceran Mallophaga of the family Menoponidae were examined 
from 53 species or subspecies of hornbills. Descriptions and illustra- 
tions are presented for 22 species in three genera of hornbill Meno- 
ponidae of which 14 species are new. The genus Chapinia now 
contains three species-groups and 17 species of which 12 are new. 
The genus Bucerophagus now contains two species-groups and three 
species. The new genus Bucerocolpocephalum type emersoni is 
erected here for two new comb-bearing species. The new species 
are as follows: Chapinia fasciati, C. camuri, C. clayae, C. wanitt, 
C. malayensis, C. hoplai, C. boonsongi, C. wenzeli, C. blaket, C. tray- 
lori, C. lydae, C. muesebecki, Bucerocolpocephalum emersoni, and B. 
deignani. New synonymy is C. acutovulvata (Piaget, 1881) (=C. 
mjoberg. (Kichler, 1947)). New type designations are: A neotype for 
Chapinia hirta (Rudow, 1866), a neotype for Bucerophagus forcipatus 
(Nitzsch, 1874), and a lectotype for C. bucerotis (Kellogg, 1908). 
Differential characters are listed for genera, species-groups, and 
species, and a key is provided for separating the species. 
The amblyceran species-groups are confined to the Ethiopian 
region or to the Oriental and Australasian regions as shown in a 
table of the hornbill hosts, their distribution, and amblyceran para- 
sites. TJockus is the only hornbill genus with amblyceran lice that 
is present in both the Ethiopian and Oriental regions; however, 
Chapinia clayae of the acutovulvata species-group from the Oriental 
species of Tockus resembles C. acutovulvata from Oriental species of 
Anthracoceros more closely than species of the lophocerus species- 
group from Ethiopian species of Tockus. It would appear, that 
there has been more recent contact between the Oriental species of 
Tockus and Anthracoceros, whose ranges overlap, than between the 
more closely related Oriental and Ethiopian species of Tockus.
