Distribution: Queensland, Bismarck Is. 



Material examined: Mindanao, Zamboanga del Sur, Lemesahan, 

 600 m, 7.IX.1958, 1 9 (H.E. Milliron) (BMH). Compared with a 9 

 specimen from Aru Is., genit. slide 5513 (LM). Further material 

 studied, North New Guinea, Dampier Island, Kar Kar, II. 1914 

 (Meek), 2 d^, genit. shde 5786. New Hannover, III-IV.1923 (A.S. 

 Meek), 1 9, genit. slide 5787 (BM). 



Male genitalia: Very similar to those of A. diacrita, new species, 

 but differing by the following points. AneUus lobes shorter, distinctly 

 shorter than the finger-shaped stalks of the coremata (indicated 

 in figures by a small arrow). The upturned paired saccus is more 

 sclerotized, left arm shorter than right, each A\dth a more prominent 

 process beyond middle. 



Female genitaha show more differences; sterigma, similarly weak 

 but less broad; cestum-like sclerite much narrower, semi tubular. 

 Ductus bursae not markedly separated from corpus burase, the latter 

 less scobinate.
