Diagnosis

The new species belongs in species group II, of Mendivil-Nieto et al. (2020). It is similar to Neurostigma angelicum sp. nov. in wing venation. It differs from the latter by having the phallosoma somewhat narrow basaly and curved inwards anteriorly, posteriorly with a slight concavity, the posterior process of the aedeagal arch long, wide, with the distal margin concave, the external margin with an abruptly long indentation, and the internal margin with a slight indentation; the endophallus with two distinctly sclerotized areas, with separate endophallic sclerites touching anteriorly, posteriorly separated by a membranous area, each of these endophallic sclerites with denticulated posterior margin with numerous small acuminate and anteriorly coiled projections giving rise to a spiral area ( Fig. 13C View Fig ).

Etymology

This species is dedicated to Dr Patrícia do Rosário Reis, from the University of the State of Amazonas (UEA), in recognition of her great contribution to the teaching of science in more remote areas of Amazonas, and for her friendship and affection.
