Almeida, Flavio Roberto De Albuquerque, Carvalho-Filho, Fernando Da Silva, Castro, Heitor Antunes De & Fernandes, Jose Antonio Marin, 2019, Two new species of Hoplonannus (Heteroptera: Schizopteridae: Schizopterinae) from the Brazilian Amazon, Zootaxa 4658 (2), pp. 355-367 : 356

Key to species of Hoplonannus (based on male specimens)

Hoplonannus brunneus was not included because only the female is known.

1. Posterior margin of mediotergite 7 with an elongate anteriorly curved process ( Figs 3 A–B; 5A–B); right paramere curved ( Figs 3A; 3D ; 5A; 5D )...................................................................................... 2

- Mediotergite 7 without a process ( Silveira et al. 2019, fig. 10); right paramere almost straight ( Silveira et al. 2019, fig. 10)................................................................................. H. australis Silveira et al.

2. Anophoric process with widened basal portion and thin sickle-shaped distal portion ( Emsley 1969, figs 141; 142A); right paramere with one or two elongate distal digitiform process ( Emsley 1969, figs 141; 142)............................... 3

- Anophoric process not widened at base, distal part laterally bent ( Figs 3A; 3E ; 5A; 5E ); right paramere with two small claw-like projections ( Figs 3A; 3D ; 5A; 5D )........................................................................ 4

3. Right paramere apically with two thin and elongate digitiform processes ( Emsley 1969, fig. 141)...................................................................................................... H. paenebrunneus Emsley

- Right paramere apically with two short and rounded processes and one elongate digitiform process ( Emsley 1969, fig. 142)...................................................................................... H. craneae Emsley

4. Anophoric process slender and apically bifid ( Fig. 3A; 3E )......................................... H. bifidus sp.n.

- Anophoric process robust and not bifid apically ( Fig. 5A, 5E )..................................... H. robustus sp.n.
