Mirollia Stål, 1873

Mirollia Stål 1873 , Oefv. K. Vetensk.-Akad. Forhandl. 30(4): 42

Type species: Locusta carinata Haan, 1842 (= Mirollia carinata carinata ), by subsequent designation ( Stål 1874)

History. 34 species and one subspecies were currently included in Mirollia ( Eades et al. 2011) , eight described until 1930 (Haan 1842, Hebard 1922, Karny 1925, 1926, Shiraki, 1930), three until 1962 ( Bey-Bienko, 1957, 1962), and the remainder since 1998 (Gorochov 1998, 2003, 2005, 2008, Gorochov & Kang 2004, Ingrisch 1998, Ingrisch & Shishodia 1998, 2000, Mu, He & Wang 1998, Shi, Chang & Chen 2005). Two of those species are transferred to the new genus Hemimirollia in the present paper, and one species to the genus Amirollia ; seven species are described as new.

Diagnosis. Easily recognised by the wide, rather uniformly coloured tegmen with rounded apex, the large suboval stridulatory area of the male tegmen, and especially by the large male phallus sclerites that are often even visible in situ between the cerci (Figs. 14C, E, 15G).

Description. Fastigium verticis in typical forms moderately sloping anteriorly but ocelli projecting; with an obtuse angle before tip. Disc of pronotum broadly rounded into paranota; only in apical area flattened. Tegmen often broad, of nearly equal width throughout or faintly widening towards apical area; apex broadly rounded (Figs. 2J–S). Male stridulatory area roughly triangular with rounded angles (Fig. 12). Male cerci hook-shaped with apex recurved or with modification derived from this character (see discussion under M. tawai sp. n.). Male phallus with up to three pairs of large sclerites usually protruding behind body and in situ visible between cerci (Figs. 16–18). Male second abdominal tergite, in some species up to fourth tergite, setose in middle. Female subgenital plate with apico-lateral angles projecting; area in between variable. Ovipositor sickle-shaped, rather broad with apex obtuse; margins subsmooth or finely serrulate.
