Material examined. -

Holotype: ECUADOR • ♂; old Baeza; 10 Jul. 1985; G.K. Morris; MLP . Paratypes: ECUADOR • 3 ♂♂; old Baeza ; 10 Jul. 1985; G.K. Morris leg.; ANSP • 1 ♂; old Baeza; 23 Apr. 1989; G.K. Morris leg.; ANSP.

Etymology. -

Named for the alternating acute-angle direction changes of the male cerci.

Diagnosis. -

Very similar to preceding species, with slightly longer cubital vein (longer than width of mirror) and different cerci. Fastigium almost straight. Tegmina of same length as pronotum; pronotum with 1 or 3 small blackish spots on anterior margin and 3 larger spots on rear margin. Last tergite ending in two lobes. Cercus with pointed medial branch, rectangularly inward-directed; below that, another inward-directed process with thinner and downward-directed appendage terminating in acute spinule. The structures below the cerci, mentioned for the previous species (see notes on comparison with A. ridiculosa above), here have obtuse posterior tips.

Measurements. -

Pronotum 4.0 mm, tegmina 4.3 mm, hind tibiae 7.6 mm.
