Diagnosis

Dry marks either around the tubercles or restricted to their tips, but in both cases all around dorsal scutum (only in Amazochroma   gen. nov. and Discocyrtanus   , absent in Roeweria   ; contrasting with Discocyrtus   and some Mitobatinae   [e.g., in Ischotherus Kury, 1991, Mitobates Sundevall, 1833   Neoancistrotus Mello-Leitão, 1927   , Promitobates Roewer, 1913   , Ruschia Mello-Leitão, 1940   ] where it is absent and with other Mitobatinae   which possess dry marks arranged in broad stripes, often cruciform [e.g., in Discocyrtoides Mello-Leitão, 1923   , Longiperna Roewer, 1929   ). Ocularium convex, with a median depression (contrasting with the convex form without depression in Discocyrtus   and Discocyrtoides   or rectangular form in Mitobates   ). Mesotergum divided into 4 areas (same as in Discocyrtus testudineus Holmberg, 1876   and Mitobatinae   ). Area I with a pair of conspicuous paramedian tubercles (same as D. testudineus   , absent in D. crenulatus Roewer, 1913   and Discocyrtoides   ). Retrodorsal distal apophysis of Cx IV of males with only a main tubercle (absent in Amazochroma pedroi   gen. et sp. nov., contrasting the form with a geminated tip present in Discocyrtus   and some Mitobatinae   ). Distal part of the VP of penis forming a trapezium, with an apical minor base (contrasting with a trapezium with an apical major base occurring in Discocyrtus   and Discocyrtoides   or the M-form of Mitobates   ). Macrosetae C1–C3 of VP elongate and slender (contrasting with the short and thick form found in Discocyrtus   and Mitobatinae   ). Macrosetae C1–C3 insertion with C 3 set widely apart from the other C, forming a diastema (present in Amazochroma   gen. nov. and Roeweria   , contrasting with all macrosetae C placed distally with subequal intervals between them as found in Discocyrtanus   and with macrosetae C placed distally, united as in Discocyrtus   and Mitobatinae   ). Ventral of glans process extremely reduced or absent (contrasting with the presence of a stem and a flabellum in Discocyrtus   and Mitobatinae   ). Stylus sigmoid, strongly bent to dorsal proximally and overall curved to ventral more distally (present in Amazochroma   gen. nov. and Discocyrtanus   , contrasting with the C-shape, overall arched to dorsal found in Roeweria   and the substraight shape as in Discocyrtus   and Mitobatinae   ). Angle of basal curvature of stylus around 90 degrees (in opposition to form with less than 90 degrees in Discocyrtus   and Discocyrtoides   or more than 90 degrees in Mitobates   ). Apical winglets of stylus (present in Amazochroma   gen. nov., Discocyrtanus   and Roeweria   , absent in Discocyrtus   and Mitobatinae   ).
