Bucerophagus africanus Bedford 
Fiaures 55, 56, 63, 68, 69 
Bucerophagus africanus Bedford, 1929, p. 509, figs. 11,12. [Type host: Bucorvus 
schlegeli Roberts= Bucorvus leadbeateri (Vigors, 1825).] 
Bucerophagus africanus Bedford—Hopkins and Clay, 1952, p. 64. 
Clay (1951la) stated that according to Mr. G. H. E. Hopkins 
Bucerophagus africanus also occurred on Bucorvus abyssinicus. 
Male: As illustrated in figure 69. Larger than either Bucerophagus 
forcipatus or B. productus except for length of head (table 12). Meta- 
sternal plate trapezoidal, expanded anteriorly, with 30-34 setae 
(fig. 68c). Each lateral margin of abdominal tergites III-VIIT with 
two short setae between the spiracle and postspiracular seta except 
for tergites III and VIII each with one short seta. Abdominal 
sternite I with 40 total setae and abdominal sternite II with 62 
total setae. Abdominal sternite VIII with central T-shaped plate 
(fig. 69d). Genitalia as shown in figure 63. 
Female: As illustrated in figure 68. Approximately the same size 
as Bucerophagus productus: larger than B. forcipatus in all measure- 
ments except width of metathorax (table 12). Resembles the male 
except that metasternal plate has 36-42 setae. Each lateral margin 
of abdominal tergites III-VIII with 3-5 short setae between the 
spiracle and postspiracular seta except for tergite VIII with one seta. 
Abdominal sternite I with 50 total setae and abdominal sternite II 
with 86 total setae. Terminal abdominal tergite with 32-40 setae on 
posterior margin; abdominal sternite VIII with 28-38 setae on pos- 
terior margin (fig. 55). Anal fringe with 60-66 setae (fig. 56). 
Discussion: Bucerophagus africanus resembles most closely B. pro- 
ductus which, however, is not as pigmented as B. africanus. Males of 
B. africanus are only slightly smaller than females, but males of 
B. productus are much smaller than females. The metasternal plate 
is trapezoidal in B. africanus and triangular in B. productus; this plate 
has more setae in both sexes of B. africanus than in corresponding
