[39] A. bispinosus

is a distinct species of the hylean region that is relatively rare in collections. The MCZ has samples from Guyana: Kaow I. (W. M. Wheeler); Forest Settlement, Rio Mazaruni (N. A. Weber); King Frederick William IV Falls (Weber). Brasil: Belém, Pará (P. Dias). Porto Velho, Rondonia (W. M. Mann). Colombia: Valle Dept., 19 km E Buenaventura (E. I. Schlinger and E. S. Ross). Kempf (1972) lists it also from the Brasilian states or territories of Amazonas and Amapá, and from Bolivia.

Kempfs 1964 species vexator (northeastern Mato Grosso) is still known only from the types. The paratype has been reviewed, and my measurements agree well with Kempf’s, except that I make

ML 1.10 mm instead of his 1.07 mm;, the MI is thus 74, while Cl is 79.

A. oriens , from Parque Sooretama in northern Espirito Santo State, Brasil, is known only from the holotype. My measurements differ slightly from Kempf’s: HL 1.53, HW 1.18, ML 1.11 mm (Cl 77, MI 73).
