Ünal, Mustafa & Beccaloni, George W., 2017, Revision of the Madagascan genera Oncodopus Brongniart and Colossopus Saussure (Orthoptera: Tettigoniidae: Conocephalinae; Euconchophorini), with description of Malagasopus gen. nov., Zootaxa 4341 (2) : 195

Oncodopus Brongniart, 1897

Brongniart 1897: 125, 205. Type species: Oncodopus zonatus Brongniart, 1897 .

Saussure 1899: 626; Kirby 1906: 270; Karny 1912: 8, 38; Chopard 1948: 125; Gorochov 1988: 176, 180; Otte 1997: 32.

Diagnosis. Body relatively depressed dorso-ventrally ( Fig. 12 ). Fastigium of vertex elongated, simple, spiniform ( Figs. 1 , 10 ). Face almost flattened, with distinct tubercles, four of which are larger and spiniform. Pronotum almost covers tegmina in male ( Figs. 10, 11 ). Mesothorax with a large seashell-shaped mesothoracic auricle. Tympanal organ on fore tibia slit shaped. Forelegs strongly developed, large, with very strong and large spines ( Figs. 10, 16 ). Fore femur strongly widened, with a large inner spine on anterio-lateral margin; its inner and outer sides without apical spine ventrally ( Figs. 4 , 10 ). Hind tibia without apical spur dorsally ( Fig. 7 ). Male last tergite very short, without or with a shallow small median notch on posterior margin ( Figs. 13 , 43 ). Ovipositor shorter than abdomen ( Fig. 18 ).

This genus is closely related to Malagasopus gen. nov. and Colossopus Saussure. See Table 1 for comparison of these genera.
