Oliveira, Luiz Fernando M., De Alvarenga, José Geraldo G. & Brescovit, Antonio D., 2023, On the Neotropical spider genus Otoniela Brescovit, 1997 (Araneae: Anyphaenidae, Anyphaeninae), with the description of six new species, Zootaxa 5383 (1), pp. 1-23 : 15

Group quadrivittata

Diagnosis. The quadrivittata group differs from the adisi group by the absence of basal embolar apophysis, narrow and elongated embolus, a transversal pointed ventral tegular projection, two robust apical spines on the prolateral edge of the cymbium in males and an epigynal plate forming a characteristic heart-shaped atrium in females ( Figs 9C, D, F ; 10G, H, I ; 11C, F ).

Composition. O. quadrivittata , O. tigre sp. nov. and O. negrinho sp. nov..
