Fruhstorfer // Type // TYPE // Phytodecta subgeminata Chen // LECTOTYPUS Phytodecta subgeminata var. tonkinensis Chen, 1934 des. H.W. Cho 2015". Paralectotype: 1♂ (ZMHB), same data as for lectotype.

Remarks.

Gonioctena subgeminata tonkinensis (Chen, 1934) was synonymized with G. subgeminata (Chen, 1934) by Kimoto and Gressitt (1981). However, this name was removed from synonymy with G. subgeminata and raised to the species level by Cho and Borowiec (2016b). Several larvae were dissected from a female specimen; therefore, this species is ovoviviparous.
