  The depository for the holotype was not identified in the original paper that described the species, so was considered a nomen nudum until that information was published. Trionymus tetralocularis is similar to T. smithii and T. coronus, due to the presence of ceraria only on the anal lobes, circulus absent and numerous trilocular pores on the body and scarce in the ceraria. They differ because T. tetralocularis has multilocular pores and tubular canals with dorsal oral collar on the abdomen and cephalothorax, while T. smithii has them only in the abdomen and T. coronus has none of these structures on the dorsum. On the ventral surface of T. tetralocularis, multilocular pores are found in the abdomen and in the middle zone of the cephalothorax, while in T. smithii they are found only on the posterior abdominal segments and on the head, and on T. coronus only on the abdominal segments. Trionymus tetralocularis has eight antennal segments while i>T. smithii and T. coronus have seven segments. (Amun, et al., 2021)

• Structure: Adult female antennas with eight segments. With only onea pair of ceraria, located in the anal lobes formed by two or three conical setae and three or four auxiliary setae. Ventral and dorsal multilocular pores distributed over the entire surface.Tetralocular pores distributed throughout the body on both surfaces; absent on abdominal segment X of the dorsum. Circulus absent. (Amun, et al., 2021)
• General Remarks: Detailed description in Spanish and illustration in Amun, et al., 2021
