Vertex developed as an elevated, compressed, in lateral view conical process. Pronotal disc with a pattern of callose stripes. Hind femora and tibiae with conical, triangular spines that are not bent or twisted. Tegmina in males extending far beyond the abdomen tip, in females only slightly. Anal and costal margin of tegmina sub-parallel ( Fig. 17A ). Male cerci simple, cylindrical, somewhat distally narrowed, with a rounded tip and an internal tooth in the distal half ( Fig. 17B–P ). Ovipositor of females no longer than fore femora, moderately curved, tip of upper valve rounded and in lower valve tip more pointed, lateral margins not serrulate. Type species. Machimoides vivasi Rehn, 1950 , by original designation. Distribution. Andes from Venezuela to Bolivia , one species from southeastern Brazil ( Minas Gerais ) ( Map 3 ). Map 3. Distribution map of Machimoides species. Key to species of Machimoides 1. Hind femora with inner ventral margin unarmed; size larger than average for the genus (total length in males 37.5–41 mm ); tegmina long, extending beyond tip of hind femur by more than twice the length of the pronotum...................... 2 - Hind femora with inner ventral margin armed like outer ventral margin; smaller (total length in males 26.5 mm ); tegmina short, only slightly extending beyond tip of hind femur........................ Yuracare Group … M. yuracare Rehn, 1950 2. Larger (total length in males around 41 mm ); extremities and pronotum relatively elongate; hind margin of pronotal disk broadly arched; tegmina with fibrous, reticulate venation......................................... Vivasi Group …3 - Medium-sized (total length in males 35–38 mm ); extremities and pronotum relatively short; hind margin of pronotal disk transverse; tegmina with coarser, less reticulate venation......................................... Minarum Group …5 3. Male subgenital plate with a constricted, acute-angled emargination ( Fig. 17F ); internal tooth of male cerci reduced, robust and straight ( Fig. 17D–E ).................................................................. M. vivasi Rehn, 1950 - Male subgenital plate with less acutely angled emargination; internal tooth of cerci curved and thin.................... 4 4. Vertex slightly longer than scapus and pedicellus, tip obtuse; styli sub-conical and 1.5 times as long as depth of emargination of subgenital plate ( Fig. 17I ); internal tooth of cerci tapering and curved backward ( Fig. 17G–H )... M. peru Gorochov, 2012 - Vertex as long as scapus and pedicellus, tip pointed; styli cylindrical, three times as long as depth of the emargination ( Fig. 17L ); internal tooth of cerci sub-cylindrical along the entire length, very slightly inclined toward apex of cercus ( Fig. 17J–K )......................................................................... M. sofiae Cadena-Castañeda, 2013 5. Vertex longer than scapus and pedicellus, thin and strongly pointed; spines of hind femora and genicular lobes normally developed, longer than width of hind tibiae; male subgenital plate with rectangular emargination........ M. minarum Rehn, 1950 - Vertex slightly shorter or as long as scapus and pedicellus, conical with obtuse tip; spines of hind femora and genicular lobes reduced, length equal to width of hind tibia; male subgenital plate with U-shaped emargination ( Fig. 17Q )................................................................................................
