Colossopus Saussure, 1899 View in CoL

Saussure 1899: 627. Type species: Colossopus grandidieri Saussure, 1899 .

Karny 1912: 8, 39; Kirby 1906: 270; Chopard 1948: 125; Gorochov 1988: 176; Otte 1997: 27; Ünal & Beccaloni 2008: 34.

Diagnosis. Body relatively depressed dorso-ventrally ( Fig. 78 View FIGURES 76 – 86 ). Fastigium of vertex distinctly elongated, with 3 long spiniform arms ( Figs. 3 View FIGURES 1 – 9 , 76 View FIGURES 76 – 86 ). Facet almost flattened, with distinct tubercles four of which larger, spiniform. Male tegmina wavy, protruding from under pronotum and almost half of them visible from above ( Figs. 76, 77 View FIGURES 76 – 86 ). Tympanal organ on fore tibia slit shaped. Mesothorax with a large seashell shaped mesothoracic auricle. Forelegs ( Fig. 76, 83 View FIGURES 76 – 86 ) strongly developed, large, with very large and robust spines. Fore femur thickened, with a large inner spine on anterio-lateral margin; its outer and inner sides armed with a large apical spine ventrally ( Figs. 6 View FIGURES 1 – 9 , 76 View FIGURES 76 – 86 ). Hind tibia with an apical spur dorsally on inner side ( Fig. 9 View FIGURES 1 – 9 ). Male last tergite long, posterior margin elongated backward, with a distinct narrow median incision ( Fig. 80 View FIGURES 76 – 86 ). Ovipositor longer than abdomen ( Fig. 85 View FIGURES 76 – 86 ).

This genus is most closely related to Malagasopus gen. nov. and Oncodopus Brongniart. See Table 1 for comparison of these genera.
