Ramos-Pastrana, Yardany & Córdoba-Suarez, Eric, 2023, First records of Pieza Evenhuis, 2002 (Diptera: Mythicomyiidae: Mythicomyiinae) from Colombia, with description of a new species from arid zones of a Tropical dry forest, Zootaxa 5343 (4), pp. 364-374 : 370-371

Pieza rafaeli Mendes, Lamas, Evenhuis & Limeira-de-Oliveira, 2019

Figs 16–21 , 23

Using the key in Mendes et al. (2019) our specimens key to the Brazilian P. rafaeli Mendes et al., 2019 . There are some slight differences, but we prefer for now to identify it as P. rafaeli until more specimens become available and we can better ascertain whether the differences are intra- or inter-specific.

Intraspecific variability in females. Mendes et al. (2019) provided a complete description and illustration of the Brazilian holotype; we provide here a comparison of the variations between the Colombian and Brazilian female specimens (between square brackets, when comparable). Body color predominantly dark brown to black ( Figs 16– 19 ) [versus Body color predominantly brown, see figures 43–45 in Mendes et al. (2019)]; inner posterior projection of the genital fork not interrupted medially ( Figs 20–20a, 21 ) [versus inner posterior projection of genital interrupted medially, see figure 51 in Mendes et al. (2019)]; anterior margin of genital fork with acute projection ( Figs 20–20a, 21 ) [versus anterior margin of genital fork rounded, see figure 51 in Mendes et al. (2019)]; sperm pump with smooth surface ( Figs 20–20b, 21 ) [versus sperm pump with transverse striations, see figure 51 in Mendes et al. (2019)]; apex of spermathecal reservoir with appearance divided as if forming a head ( Figs 20–20c, 21 ); [versus apex of spermathecal reservoir without this appearance, see figure 51 in Mendes et al. (2019)].
