Glenea diversenotata Schwarzer, 1925 is reinstated from a subspecies of G. tonkinea Aurivillius, 1925 to species level and G. neohumerosa Lin & Yang, 2011 is a new junior synonym. Some biological information on G. diversenotata is recorded for the first time, including pictures of the larva and pupa. G. quadriguttata Pic, 1926 is reinstated from a subspecies of G. lacteomaculata Schwarzer, 1925 to species level. Lectotypes for G. lacteomaculata and G. quadriguttata are designated. A modified key to the related species is presented.
Saperdini , new synonym, lectotype, Taiwan, Oriental region
Glenea diversenotata Schwarzer, 1925 and G. quadriguttata Pic, 1926 were described from Taiwan and N. Vietnam, respectively. Later, the former was downgraded as a subspecies of G. tonkinea Aurivillius, 1925 and the latter as a subspecies of G. lacteomaculata Schwarzer, 1925 by Breuning (1956). Comparison to the type materials, however, reveals that each of them should be reinstated to species level from subspecies level. We therefore present the new taxonomic decisions, justifications, and full synonymies below.
Types and other material studied are deposited in the following institutions:

Breuning (1956) treated G. diversenotata Schwarzer as a subspecies of G. tonkinea Aurivillius, 1925. The first author examined a photograph of the holotype of G. diversenotata Schwarzer, 1925 (taken by Nobuo Ohbayashi, Japan) and a photograph of a live specimen matching it from Taiwan (taken by Yu-Long Lin, Taiwan). Our study of these additional materials necessitates a new synonymy of G. neohumerosa Lin & Yang, 2011. We can find no morphological differences to maintain them as separate species. Likewise, our examination of the types of G. diversenotata and G. tonkinea leads us to review the taxonomic position of them since Breuning (1956) that G. diversenotata is a subspecies of G. tonkinea. We can find no morphological support for that treatment by Breuning. They are easily separated from each other by the following characters – Glenea tonkinea: vertex and occiput of the head with two separate, longitudinal vittae of white pubescence; white elytral maculae more slender and transverse; outer, basal, white, elytral maculae anterolaterally positioned relative to the larger, basal, sutural maculae; outer apical spine of elytra weakly produced; — G. diversenotata: vertex and occiput with vittae partially fused, not separate; white elytral maculae more rounded; outer basal elytral maculae parallel with the larger, basal, sutural maculae; outer apical spine of elytra pronounced.

Breuning (1956) had previously treated G. quadriguttata as a subspecies of G. lacteomaculata. We have found the following morphological differences between them — Glenea lacteomaculata: vertex and occiput of the head with two separate, longitudinal vittae of white pubescence; punctures at the base of the elytra denser and more irregularly spaced than in G. quadriguttata; central-most, white elytral maculae more slender, transverse and oblique; elytral apex without acute or toothed angles; — Glenea quadriguttata: head with vittae fused, not separate; central-most, white elytral maculae almost rounded; elytral apex with small sutural and outer apical teeth. With these differences, G. quadriguttata is reinstated as an independent species.
