It differs anyway by the less reduced gill ventral lamella, bearing ≥ nine filaments whereas in Nonnullidens, ventral lamella bears at most eight filaments (in N. mariae, it can also reach ten filaments). Posterolateral projections of the abdomen are present on segments V – IX, VI – IX or VII – IX, whereas they are present on segments VIII – IX in Nonnullidens (VII – IX in some species). Posterior margin of tergite VIII always bears small denticles, whereas they are absent in Nonnullidens (present and well-developed in N. mariae). Finally, the eggs of Kosminympha are similar in shape to those of the genus Thraulus, being elongated and bearing attachment structures at each pole, whereas they are rounded and without attachment structure in Nonnullidens .</p><p>Distribution.</p><p>The genus Kosminympha is only known from Papua New Guinea and has been found on the eastern part of the island; the genus has yet not been recorded from Indonesia Papua.</p></div>	https://treatment.plazi.org/id/2A3E61887BB85BBEB47E6423FE6BC107	Public Domain	No known copyright restrictions apply.

Contrary to Grant (2024) the ventral side of labrum can bear not only a row of short stout setae (e. g., Fig. 12 B) but in some species scattered stout or thin setae (e. g., Fig. 18 B). The hypopharynx does not always bear a “ small, rounded, posterolateral projection on arms of the superlingua ”, compare for instance Fig. 21 F and Fig. 29 F.</p><p>Species composition.</p><p>The species Thraulus eatoni Grant, 2024 [Indonesia Sulawesi], Thraulus parentalis Grant, 2024 [peninsular Malaysia], Thraulus petersorum Grant, 2024 [peninsular Malaysia, east Malaysia Sabah], Thraulus semicastaneus (Gillies, 1951) [southern India], Thraulus thraker Jacob, 1988 [Bulgaria] cannot be assigned to a subgenus because their nymphs are still unknown.</p></div>	https://treatment.plazi.org/id/0823F45AA6A9592196EF62F8F6B54369	Public Domain	No known copyright restrictions apply.
