description: Anagonia perplexa sp. nov.    
Fig. 78  
 Types. Holotype male in ANIC no. 29-029365, 12 mi W of Pemberton, WA, 31 Mar. 1968, IFBC & MSU, terminalia in tube 346. Paratypes (all males):— Western Australia: 2 specs. as for holotype, but T.t. 319 and 345; as for holotype, but 5 Apr. 1968, T.t. 333; 15 mi SE of Donnybrook, 29 Mar. 1968, T.t. 343; 2 specs. 5 mi N of Nannup, 1 Apr. 1968, IFBC & MSU, T.t. 318 and 349.   
A relatively large and pale species, but with body hairs all dark.  
 Male. Head. Width 3.0–3.2, mean 3.12 mm. Frons rather broad, FrW/HdW mean 0.25; Ivb/Vb-E 1.0–1.2, mean 1.06. Eye sparsely to moderately haired. Fronto-orbital plate with rather profuse long fine hairs. Ground colour of parafacial mainly mid- to (rarely) dark-brown, pale-brown along anterior margin; gena pale brown. Ocellar setae rather variable, from finely to moderately developed, but always distinct; postocellar setae 2 or (rarely) 3. Upper occiput with a complete row of black setae behind the postocular row and some scattered black setae behind those.   
 Thorax. Median vitta strongly developed. Presutural intraalar extremely fine or not developed on at least one side, often on both. Intrapostalars lacking. Scutellum brown with narrow dark basal band; apical scutellars well developed but highly variable in shape.   
 Legs. Tibiae paler brown than femora, often conspicuously so. Hind tibia with Pd1 usually a little shorter than Sdd, ratio 0.7–1.0, mean 0.87.   
 Abdomen. Colour unremarkable, as in, for instance, A. rufifacies (pale form). Submedian apical bristles on tergite 3 barely or not at all differentiated.   
 Terminalia (Fig. 78). Structurally, rather like a magnified version of A. minor (above). Cercus with prominent basal lobe, separated from apical part by a distinct “notch”, with usual small stout bristles and a patch of fine microtrichiae on the margin adjacent to the notch; apical part curved, thumb-like, a little shorter than basal part, its apex about at the bend of the surstylus, with stout fine setulae over most of its posterior surface and a band of microtrichiae along the lateral surface, extending into the basal part. Surstylus rather abruptly angled, apical part narrowed. Epiphallus well developed, with pointed or rounded apex.   
 Female. Not known with sufficient certainty. Two specimens captured along with males at light may belong here, but the evidence is not compelling.   
 Distribution. All specimens came from localities in southwestern Western Australia.   
 Biology. Nothing known except that adults come to light.   
 Notes. The species is distinguished from others in the complex by the fine details of the shape and vestiture of the cercus. Its name is self-explanatory [I am not sure whether this would pass muster with the new rules].
