seta between the spiracle and postspiracular seta. Abdominal 
sternite II with 32-42 total setae and one median row of setae on 
posterior margin. Terminal abdominal segments similar to those 
of C. boonsongi. Genitalia as shown in figure 16, endomeres with 
paired plates. 
Female: Smaller than Chapinia traylori in all measurements except 
length of head (table 2). Resembles the male except that the venter 
of the third femora and posterolateral margins of abdominal sternites 
IV-VI each have small scattered brushes of normal setae which are 
not as numerous on abdominal sternite VI. Abdominal sternite II 
with 52-64 total setae. Terminal abdominal tergite with 10-16 
long and 8-14 short setae on posterior margin; abdominal sternite 
VIII with 14-18 setae on posterior margin (fig. 43) and with internal 
sclerite having slender posteriorly divergent margins. Anal fringe 
with 34-40 setae (fig. 42). 
Discussion: Chapinia blakei resembles most closely C. wenzeli. The 
venter of the third femora and posterolateral margins of abdominal 
sternites IV-VI each have small scattered brushes of normal setae in 
females of C. blakei and in both sexes of C. wenzeli. The male genitalia 
have endomeres with paired plates in C. blakei but paired outer rims 
in C. wenzeli. However, the paired plates may be split in C. blaket, 
giving the appearance of paired outer rims and inner plate, but the 
inner plate in this case is unsymmetrical. The male genitalia of 
C. traylori also have endomeres with paired plates, but the posterior 
extension of the endomeres is split in C. traylort and not split in 
C. blaket. The female abdominal sternite VIII has on the posterior 
margin at most 18 setae in C. blakei but at least 18 setae in C. wenzelt, 
and the internal sclerite with slender posteriorly divergent margins, 
present in C. blakei, is absent in both C. wenzeli and C. traylori. The 
female anal fringe has at most 40 setae in C. blakei and at least 40 
setae in C. wenzelt. 
Material examined: 13 males and 16 females from fresh and dried 
material collected in the Philippines.
