Chapinia clayae, new species 
Fiaures 8, 33, 34 
Both sexes are smaller than corresponding sexes of Chapinia traylori 
in all measurements except length of head (tables 1, 2). 
Male: Venter of third femora and posterolateral margins of abdom- 
inal sternites [V—VI each with small scattered brushes of normal setae. 
Each lateral margin of abdominal tergites II-VI with a short seta 
between the spiracle and postspiracular seta. Abdominal sternite IT 
with 38-50 total setae and one median row of setae on posterior 
margin. Terminal abdominal segments similar to those of C. acuto- 
vulvata. Genitalia as shown in figure 8, endomeres with small inner 
plate and paired outer rims. 
Female: Resembles the male except that abdominal sternite II has 
66-76 total setae. ‘Terminal abdominal tergite with 12 long and 12 
short setae on posterior margin; abdominal sternite VIII with 22-30 
setae on posterior margin (fig. 33). Anal fringe with 38-44 setae 
(fig. 34). 
Discussion: Although smaller in size, Chapinia clayae resembles 
most closely C. acutovulvata. The venter of the third femora and 
posterolateral margins of abdominal sternites IV-VI each have small 
scattered brushes of normal setae in C. clayae but large thick brushes 
of normal setae in C. acutovulvata. The male genitalia have endomeres 
possessing on each outer rim a triangular internal knob that is wider 
than long in C. clayae but longer than wide in OC. acutovulvata. The 
female terminal abdominal tergite has on the posterior margin at most 
24 setae, of which approximately one-half are long and one-half are 
short, in C. clayae, but at least 26 setae, of which approximately 
two-thirds are long and one-third are short, in C. acutovulvata. In 
addition this margin has on each side of the midline at most four long 
setae in C. clayae but at least six long setae in C. acutovulvata. The 
female anal fringe has at most 44 setae in C. clayae but at least 44 
setae in C. acutovulvata. 
Material examined: 19 males and 29 females from fresh and dried 
material collected in India and Nepal. 
Type host: Tockus birostris (Scopoli, 1786). 
Type material: Holotype male, allotype female, and 2 male and 4 
female paratypes on same slide from Rajputana, India, March 1937, 
Meinertzhagen 8855-8856, BMNH. The holotype and allotype 
are each the second from the right in the rows of males and females 
as seen under the microscope. Paratypes: 5 males and 12 females 
with same data except Meinertzhagen 8932; 1 male from Nepal,
