description: Patellapis (Chaetalictus) disposita (Cameron 1905)   
 Halictus dispositus Cameron, 1905a: 239.   
(Figs. 67a–g; 68a–f)  
 Diagnosis. The male is characterised by a broad, hyaline, hairless, dorso-lateral projection on the gonostylus, which is similar to the male of P. pondoensis. Both are easy to distinguish by having a different number and thickness of erect bristles on the posterior margin of S4. The male of P. pondoensis has 6 weak bristles, whereas that of P. disposita has 12 strong bristles. The female of P. disposita is similar to that of P. platti, but P. platti lacks the oily bluish shine on the scutum. Further, they differ in the colour of metasomal terga that are predominantely reddish in P. platti and usually brownish-black in P. disposita.
