Figs 3 , 9F , 10F , 18 , 19 Gymnacoustes unizip (' Gymnacoustes unizip ' Morris 1987 , field name: Banos Blackface) Material examined. - Holotype : ECUADOR • ♂ ; Tungurahua ; 25 Jul. 1985 ; G.K. Morris leg.; MLP . Paratypes : ECUADOR • 1 ♂ ; Tungurahua ; 25 Jul. 1985 ; G.K. Morris leg.; SN-5, 85-5, Rec. ; ANSP • 2 ♂♂ ; Tungurahua ; 26 May 1983 ; G.K. Morris leg.; ANSP . Etymology. - Referring to the significant midline emargination of the posterior margin of abdominal tergite IX. In an excess of caution, we are careful to avoid a species name relating to song- e.g., Gymnacoustes unizip , as given in the ISV poster-for both the preceding A. ortoni and A. incisa . The two sing in earshot of each other and solitary vs. doubled zips easily distinguish their songs, but some confusion in field naming might have led to misapplication of song to these species. Diagnosis. - Similar to previous species. Tegmina almost twice as long as pronotum. Pronotum with blackish spot on prozona and posteriorly diverging blackish spot on metazona, both spots connected by more narrow dark coloration in between. Last tergite with deep narrow cleft, wider in distal portion, and the lobes formed by this division with inward-directed tips sporting tiny teeth. Cerci with obtuse dorsal tip as in previous species; below that, with curved inward-directed process; ending also sort of two-tipped, with the lower tip developed as short spinule. Styli almost twice as long as wide. Measurements. - Pronotum 5.0 mm, tegmina 6.3 mm, hind tibiae 8.4 mm.
