Key to Triplocania species of the magnifica group

Adapted from Silva-Neto & Garcia Aldrete (2019)

1. Hypandrium of three sclerites; mesal endophallic sclerite U-shaped, wide at the base and narrowing posteriorly; ninth sternum almost elliptic (see Figs 6 , 9 and 12 in Silva-Neto & Garcia-Aldrete 2019)............................... T. magnifica

-. Hypandrium of five sclerites; mesal endophallic sclerite not U-shaped; ninth sternum V-shaped or with sclerotized line Vshaped (see Figs 5, 7, 8 , 10, 11 and 13 in Silva-Neto & Garcia-Aldrete 2019)...................................... 2

2. Hypandrium with median posterior process of the central sclerite short, posterior pair of sclerites slender, elongate, proximally overlapped over central sclerite, with field of papillae on distal half; phallosome with a mesal anterior area bag shaped, mesal posterior endophallic sclerites, anteriorly and posteriorly concave, with two projections on each side, slightly curved inwards, posteriorly with two stout projections, leaving between them a small concavity; ninth sternum broadly triangular, width greater than antero-posterior length. (see Figs 5, 7 and 10 in Silva-Neto & Garcia-Aldrete 2019)........................ T. rosae

-. Hypandrium with median posterior process of the central sclerite long, posterior pair of sclerites stout, curved outwards, not overlapped over central sclerite, with field of papillae on distal half; phallosome not like described above; ninth sternum anteriorly concave, posteriorly rounded, width smaller than antero-posterior length. (see Fig. 11 in Silva- Neto & Garcia-Aldrete 2019)........................................................................................ 3

-. Phallosome with only one pair of endophallic sclerites, with a mesal posterior endophallic sclerite anteriorly concave but with a slender and elongate projection on each side, directed anteriorly and smoothly curved outwards, anteriorly concave in lateral, posteriorly wider in the middle, convex in lateral and with a mesal and robust posterior projection with a border not jagged; hypandrium with side sclerites wider in the middle, narrowing at the not acuminate ends, with posterior pair of sclerites anteriorly almost triangular and narrow, widening abruptly posteriorly, distally gently curving outwards, ninth sternum anteriorly concave in the middle and posteriorly slightly concave with a line of pigment whose origin is anterior, forming a V close to the posterior margin, delimiting together with the line of anterior concavity a mesal area uniformly pigmented with the exception of the posterior ends ( Figs 5, 6–7 and 13 )............................................. T. oiapoque n. sp.
