Neotropiconyttus dama was described based on specimens from the State of Pará , Brazil ( Burmeister 1838 ). In the MFNB , there are three female type specimens of N. dama . One specimen is labeled as “ Typus ” (Figs 43–45 ); the others are labeled as “ Paratypus ” (Figs 46–51 ). All of them are considered as syntypes in this work, following Art. 73.2 of the ICZN (1999 ). Notably, all the syntypes have a green label stating, besides the name of the Brazilian state of Pará , the name of “ Sieber. ” Friedrich Wilhelm Sieber was a servant and preparator of Johann Centurius Count von Hoffmannsegg, who obtained permission from the King of Portugal to visit Brazil to collect insects. Leaving Lisbon in 1801, Sieber went to the Province of Pará , where he stayed for 12 years, collecting not only in the vicinity of Belém but also in different areas of the provinces of Pará and Rio Negro (currently, state of Amazonas) ( Papavero 1971 ). Therefore, the precise type locality of the species in this large region remains uncertain. Figures 43–51.

Morphological remarks. General length 12‒12.5 mm . General color blackish; labium with distal 1 / 2 of second and third visible labial segments variably paler; neck, prothorax, and mesothorax mostly reddish; humeral angles, posterior margins of mesopleura and mesosternum, and most of metapleura dark to blackish. Legs: except for fore coxae and a portion of fore trochanters, which are reddish, the remaining portions of the legs mostly dark to blackish; dorsal portion of distal ~ 2 / 3 of fore femora paler, and ill-defined pale yellowish annuli; middle and hind femora with submedian distal pale whitish to yellowish annuli; hemelytra darkened. Abdomen: sternites mostly yellowish with the following portions or markings blackish: narrowly basally on sternite II and adjacent connexival portion; on segments IV ‒ VII: connexivum and shortly adjacent portion, median markings of variable extension on respective sternites, and genitalia.
