NO. 3558 MALLOPHAGA—ELBEL 31 
Chapinia blakei is named for Dr. Emmet R. Blake, Curator of Birds, 
Chicago Natural History Museum, in appreciation for permission to 
examine hornbill skins for Mallophaga in that museum. 
Chapinia traylori, new species 
Figures 17, 25, 26, 44, 45 
Male: As illustrated in figure 26. Slightly larger than Chapinia 
clayae, C. acutovulvata, C. malayensis, C. hoplai, C. boonsongi, C. 
wenzelt, C. blakei, and C. lydae in all measurements except length of 
head in C. clayae, C. acutovulvata, C. hoplai, C. boonsongi, C. blakei, 
and C. lydae, width of head in C. acutovulvata, width of metathorax in 
C. blakei, and width of abdomen in C. malayensis; smaller than C. 
wanitt in all measurements except width of prothorax and width of 
metathorax; approximately the same size as C. robusta (table 1). 
Venter of third femora and abdominal sternites IV-VI each without 
brushes. Each lateral margin of abdominal tergites II-VI without a 
short seta between the spiracle and postspiracular seta. Abdominal 
sternite II with 24-42 total setae and two median rows of setae 
although the anterior row has widely separated setae. Terminal 
abdominal segments as shown in figure 26e. Genitalia as shown in 
figure 17, endomeres with paired plates. 
Female: As illustrated in figure 25. Larger than Chapinia waniti 
and Chapinia acutovulvata in all measurements except length and width 
of head; slightly larger than other Chapinia in all measurements except 
length of head (table 2). Resembles the male except that abdominal 
sternite II has 38-58 total setae. Terminal abdominal tergite with 
10 long and 6-10 short setae on posterior margin; abdominal sternite 
VIII with 14-20 setae on posterior margin and with small triangular 
internal sclerite (fig. 44); each lateral projection of the ventral sclerite 
between vulva and anus with 2 or 3 thick, posteriorly directed setae 
(fig. 44sp). Anal fringe with 34-40 setae (fig. 45). 
Discussion: Chapinia traylori resembles most closely C. blakei. 
The venter of the third femora and posterolateral margins of abdomi- 
nal sternites [V—VI lack brushes in both sexes of C. traylori and in the 
male of C. blakei, but these margins have small scattered brushes of 
normal setae in females of C. blakei. The male genitalia have endo- 
meres with paired plates in both C. traylort and C. blakei, but the 
posterior extension of the endomeres is split in C. traylori and not 
split in C. blakei; the paired plates may be split in C. blakei, giving 
the appearance of paired outer rims and inner plate, but the inner 
plate in this case is unsymmetrical. The female abdominal sternite 
VIII has a small triangular internal sclerite in C. traylori but a much 
larger sclerite with slender posteriorly divergent margins in C. blakei. 
Each lateral projection of the ventral sclerite between female vulva
