Hi @loarie. As you can see in MSF, there are five species listed under Xanthomantis. However, the genus Xanthomantis is a homonym of a lepidopteran genus.

"In the family Iridopterygidae, Malayamantis (nom. nov.) is proposed as replacement name for Xanthomantis Giglio-Tos,1915, as it is junior homonym of Xanthomantis Warren,1909 (Lepidoptera). Although this case was reported by Uvarov in 1940, Xanthomantis Giglio-Tos used erroneously as valid name for the related taxa so far. The necessary nomenclatural acts are summarized as follows: Pliacanthopus Giglio- Tos,1927 is treated here as valid name of the generic taxon (stat.rev.). New established Malayamantis is used here as subgenus name, together with other subgenus name Oligocanthopus Beier,1935. The following three species should be treated as Pliacanthopus (Malayamantis) malayanus (Beier, 1931) from Malaya, Pliacanthopus (Malayamantis) flavus (Giglio-Tos, 1915) from Sarawak, and Pliacanthopus (Malayamantis) bimaculatus (Wang,1993) from China (Yunnan)." (Koçak & Kemal, 2008)

And to my knowledge, the subgenus Oilgocanthopus was treated as genus in Schwarz & Roy, 2019.

I created two new genus taxa, two new subgenus taxa and five new species taxa in iNat and I swapped the Xanthomantis spp. with those new ones:

-genus Pliacanthopus
--subgenus Malayamantis (swap genus Xanthomantis with it)
--subgenus Pliacanthopus

-genus Oilgocanthopus

-Pliacanthopus bimaculatus (under subgen. Malayamantis)
-Pliacanthopus flavus (under subgen. Malayamantis)
-Pliacanthopus malayanus (under subgen. Malayamantis)
-Pliacanthopus mantispoides (under subgen. Pliacanthopus)
-Oilgocanthopus ornatus ((under gen. Oligocanthopus)

And I'm not aware of removing any internodes
