Dactylispa tuberculata Gressitt, 1950: 131 .

Type locality. China, Guangdong prov., Lianping Co.,Jiulianshan Mt., approx. 24°27.3′N, 114°33.8′E, 400–500 m a.s.l.

Original type series. Holotype ( LMNH) and unspecified number of paratypes ( CAS, USNM) from the same locality as the holotype.

Current status. Valid species.

Remarks. Gressitt (1950) stated that the holotype was collected on ‘ Apr. 23, 1940 ’ but it is not clear whether there is 23rd or 25th on the label as the text is partly missing. This species is very characteristic by having anterior margin of pronotum with two massive unbranched spines while other species of Dactylispa Weise, 1897 have the anterior spines with at least two branches. Weise (1897) proposed subgenus Monohispa based on this character for a single species— Hispa singularis Gestro, 1888 . Most authors did not accept the subgeneric system of Dactylispa until Chen et al. (1986) who found additional constant differences applicable at least to Asiatic species. In the same publication the authors raised Monohispa to genus level and included Gressittʼs D. tuberculata . This view was followed in recent catalogue of Palaearctic Coleoptera ( Borowiec & Sekerka 2010) . We did not study type specimens of D. singularis but based on the primary description the species seems to quite similar to D. tuberculata and perhaps the latter may represent only its geographic form.
