Friend, Herman L., Sulak, Harald, Beavogui, Abdoul Habib, Müller, Günter C., Revay, Edita E., Yakovlev, Roman V., Saldaitis, Aidas, Volkova, Julia S., Prozorova, Tatiana A. & Prozorov, Alexey M., 2025, Descriptions of three new Hypotrabala from the H. neavei species group (Lepidoptera, Lasiocampidae), Ecologica Montenegrina 89, pp. 16-37 : 21

Diagnosis. Hypotrabala neavei differs from:

1) H. lunda by darker colored forewing with more intense dark speckles (compare Figs 2–9 and 10–15 ), medially wider tegumen, shorter socius, wider valva, presence of apical plate on vesica, shorter parallel processes of the eighth sternite instead of long arcuate ones (compare Figs 27– 30 and 31–34 );

2) H. liviae sp. n. by darker colored forewing with more intense dark speckles (compare Figs 2, 4– 6, 8–9 and 16–17 ), medially wider tegumen, shorter socius, wider valva, presence of apical plate on vesica (compare Figs 27–30 and 41–42 );

3) H. pearlae sp. n. by darker colored forewing with much more intense dark speckles (compare Figs 2, 4–6, 8–9 and 18 ), almost straight processes of the eighth sternite instead of arcuate ones (compare Figs 27–30 and 40 );

4) H. maryannae sp. n. by darker orange background color of male forewing (compare Figs 2, 4– 6, 8–9 and 19–20, 22–23 ) and darker colored female forewing (compare Figs 3, 7 and 21, 24 ), narrower socia and wider valva, larger processes of the eighth sternite, presence of apical plate on vesica (compare Figs 27–30 and 43–46 ).
