Trischnaspis Ben-Dov 1974: 29. Type species: Ischnaspis bipindensis Lindinger by monotypy and original designation . accepted valid name

Systematics: Subfamily DIASPIDINAE Tribe DIASPIDINI INCERTAE SEDIS (Normark, et al., 2019) Trischnaspis is closely related to Ischnaspis from which it differs by the presence of 3 pairs of pygidial macroducts, as compared with 2 pairs in Ischnaspis and the presence of the long spine of the median lobe, which is lacking in Ischnaspis (Ben-Dov, 1974).
Structure: The main characters of Trischnaspis are a reticulated pattern which occupies the dorsopygidial area around the anal opening; presence of two pygidial lobes; presence of 3 pygidial macroducts, one between the median and second lobes and two ducts, very close to each other, just exteriorly to the 2nd lobe; the sclerotic prolongation extending from the base of the inner lobule of the 2nd lobe; presence of a long spine, longer than a median lobe, arising dorsally from the middle of the base of each median lobe; absence of gland spines between median lobes; absence of dorsal bosses on the submarginal area of the abdominal segments (Ben-Dov, 1974).
