Type species: Fruhstorferia tonkinensis Willemse, 1921 , by monotypy.

Description. Body medium-sized and well-proportioned, with sparse pubescence. Head large and shorter than pronotum. Frons slightly reclinate backwards in profile; frontal ridge broadened between antennal sockets, sulcated over the whole length and nearly reaching clypeus; lateral margins distinct, about straight and a little curved near antennal sockets; foveolae absent. Eyes large and oval. Antennae long and filiform, reaching beyond posterior margin of pronotum. Pronotum longer than broad, median keel distinct over the whole length, and lateral keel absent; three transverse sulci distinct, all interrupting median keel; prozona longer than metazona. Prosternal process short conical and pointed apically. Mesosternum with lateral lobes broadly separated from each other. Metasternum with lateral lobes close to each other but not contiguous in male and broadly separated from each other in female. Tegmina and hind wings developed both in male and female, not or just reaching, or slightly exceeding apices of hind femora, and without a series of dense and parallel short transverse veins in radial area. Hind femora with outer upper basal lobe distinctly longer than lower basal lobe, without tooth at upper median keels; lower genicular lobes broadly rounded apically. Hind tibiae slightly curved, with dense pubescence, and ecto-apical spine absent. Abdomen with developed tympanum at the lateral sides of the first segment; terminal tergite with two small triangular furculae in middle of posterior margin. Supra-anal plate triangular, sulcated longitudinally along midline of dorsum; apex slightly pointed. Cerci in male not conical, slightly broadened basally, distinctly constricted in middle, distinctly laterally compressed apically with apical part slightly or distinctly expanded; cerci in female short conical. Subgenital plate short conical with apex acute angular in male, and rectangular in female with posterior margin triangularly protruded in middle and submedian tooth distinct.

Composition. The genus consists of 13 species.

Distribution. CHINA, VIETNAM, JAPAN.

Remarks. Cornelis Willemse (1921) established the generic name Fruhstorferia to contain the new species Fruhstorferia tonkinensis Willemse, 1921 with an indication of "Dit nieuwe genus en deze soort zullen elders worden beschreven" in the foot note. However, this generic name Fruhstorferia Willemse, 1921 had been preoccupied by Fruhstorferia Kolbe, 1894 in Coleoptera , and should be treated as a junior homonym. As a result, Willemse (1922) changed the name into Fruhstorferiola when he described the detailed morphology of his new species Fruhstorferia tonkinensis Willemse, 1921 some four months later. Therefore, we should use the generic name Fruhstorferiola Willemse, 1922 as valid name according to the Article 23.1 of the Code (ICZN 1999), and the correct publishing year for the genus Fruhstorferiola should be 1922 but not 1921 as presented in the online database " Orthoptera Species File Online " ( Cigliano et al. 2019).

The species name Fruhstorferia tonkinensis Willemse, 1921 was published before 1931, provided by diagnosis given in a key and must be considered as valid name according to Articles 11.9.3, 11.9.3.1, 11.9.3.2, and 12.1 of the Code (ICZN 1999). Since the species had been transferred from the genus Fruhstorferia to the genus Fruhstorferiola , it should be considered as a recombination, and the author and publishing date should be parenthesized. Therefore, the correct the species name should be Fruhstorferiola tonkinensis ( Willemse, 1921) as in the online database " Orthoptera Species File Online " ( Cigliano et al., 2019) but not Fruhstorferiola tonkinensis Willemse, 1922 as presented in the monograph "Fauna Sinica " by Li et al. (2006).
