REVISIONARY CLASSIFICATION OF RUTILIINI III 
Kery TO SPECIES OF THE GENUS PRODIAPHANIA 
[Note: The following key is to males only. Females usually cannot be reliably associated 
with males, and it is considered that dependable keys to females cannot be given in the present 
state of knowledge; the three nominal species echinomides, vittata and walkeri cannot be included 
in the key as they have female holotypes which have not yet been associated with known 
males. FP. clavipennis is omitted as its male holotype has not been seen, and insufficient data 
is to hand for reliable inclusion.] 
I 
Sternites concealed, ventral ends of tergites meeting each other in mid ventral line 
of abdomen so that sternites are completely covered. Hind tibia without pd 
setae. Hind femur with some pv setae basally or submedially 4 genitalia 
with large foliaceous surstyli orientated in the transverse plane (Text-figs ror, 106) a 
Sternites exposed partially or completely, ventral ends of tergites separated from 
each other in mid venter of abdomen Hind tibia with one or more pd setae (very 
rarely none). Hind femur with or without pv setae. 3 genitalia with surstyli 
not of this form . : 4 
Hind tibia with a secondary fringe of semi- erect setulae on the a surface in addition 
to the main ad fringe. [dg genitalia not seen] . : P. commoni 
[No material has been seen of this species, which is only doubtfully distinct 
from biarmata] 
Hind tibia without a distinct secondary a fringe in addition to the main ad fringe 
(hairing of a surface all small, weak and virtually recumbent). ¢ surstyli and 
cerci as Text-fig. 101 or 106 . - 3 
6 genitalia with surstyli enormous in relation to Spaaidirttem and ‘sarstyli and cercl 
exceedingly slender in profile (Text-fig. 101). [Western Australia] 
P. georgei 
6 genitalia with surstyli not exceptionally enlarged in relation to epandrium and 
surstyli and cerci much broader in profile (cerci broad basally and with very 
strong apical curvature) (Text-fig. 106). [South Australia] 2 : P. biarmata 
Hind femur without any pv setae. Hind femur with av setae confined to “pics 
third or half 2 : 5 
Hind femur with some pu setae basally or - medially (very few and rather weak in 
victoyiae). Hind femur with av setae and long strong hairs irregularly along its 
whole length (except in victoriae, in which av setae confined to apical half) : 13 
Surstylus of g genitalia with a long forwardly directed basal process that is nearly 
as long as the main part of the surstylus or at least half as long (Text-figs 95, 96, 105) 6 
Surstylus of 3 genitalia not of this form, if with a forwardly directed basal process 
this in the form of a short bluntly rounded lobe (Text-figs 97-100, 103, 104) : 7 
Basal process of surstylus rounded apically and bearing a very long dense black 
hair tuft (Text-fig. 95) . . P. testacea 
Basal process of surstylus slightly bifurcate and pointed apically and its very 
short inconspicuous hairing (Text-figs 96 & 105). : . P. furcata 
Surstylus of 3 genitalia in profile strongly curved, very long ad narrow, with sparse 
hairing confined to the basal part (e.g. Text-fig. 100) : 8 
Surstylus of § genitalia in profile moderately broad and only at most slightly curved, 
usually (not funebris) with rather long dense neeenS on most of its length (Text- 
figs 97-99, 103, 104). 9 
Surstylus of ¢$ genitalia ecuenely elender me of even code along its Jength 
(fig. 2C in Paramonov, 1968 : 388) : : : P. brevitarsis 
Surstylus of f genitalia slightly but a. clavate, narrower near the base than on 
apical half (Text-fig. 100) - P. genitalis 
Surstylus of $ genitalia as in Text- fig. 103, hairing mainly eanaaca: to basal third and 
consisting mostly of a moderately dense bunch of long strong hairs arising from a 
swollen rounded anterobasal prominence on the surstylus. Setulae of ad fringe
