Machado, Angelo B. M., 2009, Denticulobasis and Tuberculobasis, new genera close to Leptobasis, with description of ten new species (Odonata: Coenagrionidae)., Zootaxa 2108, pp. 1-36 : 33

Tuberculobasis sp. 2

Figure 55

Specimens examined. 1 Ƥ, PERU, Loreto Department, Exploration Lodge, 50 miles, NE of Iquitos on Amazon River at junction of the Yanomano River (3º 21´59" S, 72º 47´56" W), 27-VIII-1991, S.W. Dunkle leg (SWD).

Remarks. Median lobe of hind prothoracic lobe ( Fig. 55 ) similar to that of female of T. williamsoni ( Fig. 52 ), but mesepisternal tubercles different and not connected with mesostigmal plate as in T. williamsoni ( Fig. 52 ). Tubercle of Tuberculobasis sp. 2 is unique by having the shape of a ball with a basal ring ( Fig. 55 ). This species also has top of head orange and it is most probably new. However, since it could represent the female one of the six species with unknown females, I am not naming it.
