Type species: Gryllacris ruficeps Serville 1831 = Eugryllacris ruficeps ruficeps (Serville 1831) .

Diagnosis: Eugryllacris can be recognized by the combination of the following characters: veins of forewings black ( Fig. 9F ), hindwings almost transparent ( Fig. 8D ); posterior margin of male ninth abdominal tergite with spines extending inwards from the middle of each lobe at base, length of spines shorter than half the width of ninth abdominal tergite ( Fig. 7H ). Eugryllacris is similar to Magnigryllacris , Radigryllacris , and Prosopogryllacris , but can be distinguished by the overall transparent hindwings. Magnigryllacris and Radigryllacris also differ from Eugryllacris by green veins and yellowishbrown cells of forewings when alive. Prosopogryllacris also differs from Eugryllacris by the black face (see Table 5 for details).

Included species: Eugryllacris ruficeps ruficeps (Serville, 1831) , E. comotti (Griffini, 1908) , E. gandaki Ingrisch, 2018 , E. inversa Ingrisch, 2018 , E. loriae (Griffini, 1908) , E. maculipennis bakeri (Griffini, 1915) , E. maculipennis laticauda (Karny, 1925) , E. maculipennis maculipennis (Stal, 1877) , E. maculipennis specularis (Karny, 1925) , E. moesta laurentii (Griffini, 1918) , E. moesta moesta ( Brunner von Wattenwyl, 1888) , E. moestissima ( Brunner von Wattenwyl, 1888) , E. panteli (Bolivar, 1900) , E. poultoniana (Griffini, 1909) , E. princeps (Stal, 1877) , E. ruficeps stigmaticeps (Karny, 1929) , E. ruficeps viridiceps (Karny, 1926) , E. sarawaccensis (Karny, 1928) , E. sordida (Fritze, 1908) , E. viridescens (Walker, 1870) , E. vittipes lineosa (Walker, 1869) , E. vittipes nasalis (Walker, 1869) , E. vittipes vittipes (Walker, 1869) .

Remarks: The genera Eugryllacris and Prosopogryllacris were established by Karny (1937). Gorochov (2004) proposed that the species of Prosopogryllacris from Japan [ P. japonica (Matsumura and Shiraki, 1908) , P. simulans Ichikawa 2001 , P. rotundimacula Ichikawa 2001 , P. okadai Ichikawa 2001 , and P. iriomote Gorochov 2002 ] should be transferred to the genus Eugryllacris , because the apex of their ovipositor is sharp. Taewoo et al. (2014) moved P. japonica to the genus Eugryllacris based on their genital characters. Bian et al. (2016) moved P. cylindrigera to genus Eugryllacris , and described six species of Eugryllacris from China ( E. bifoliata Bian & Shi, 2016 , E. elongata Bian & Shi, 2016 , E. fanjingshanensis Bian & Shi, 2016 , E. lobulis Bian & Shi, 2016 , E. longifissa Bian & Shi, 2016 , and E. xiei Bian & Shi, 2016 ). Ingrisch (2018) described eight new species and one new subspecies of Eugryllacris from South-East Asia ( E. crassicauda Ingrisch, 2018 , E. gandaki Ingrisch, 2018 , E. guomashan Ingrisch, 2018 , E. inversa Ingrisch, 2018 , E. serricauda Ingrisch, 2018 , E. sulcata Ingrisch, 2018 , E. trabicauda Ingrisch, 2018 , and E. vermicauda Ingrisch, 2018 , and one subspecies E. crassicauda cambodiana Ingrisch, 2018 ), and he thought that the genus was characterized by a rather wide and short head, and a pronotum combined with the following coloration of the hindwings: cross veins in light colour, green or light brown bordered by light, semitransparent bands, while the middle of cells is dark or blackish brown. The molecular results show that the genus Eugryllacris is not a monophyletic group. Therefore, two new genera Magnigryllacris gen. nov. and Radigryllacris gen. nov. are erected. The differences among these genera include: colouration of foreand hindwings, and size of ocelli ( Table 5 ). After our new classification, species of Euryllacris are mainly distributed in the Malay Archipelago, species of Magnigryllacris and Prosopogryllacris are mainly distributed in South-East Asia, species of Radigryllacris are mainly distributed in East Asia.

( Figs 7F , 8A, B , 9D )

Type species: Eugryllacris guomashan Ingrisch 2018 = Magnigryllacris guomashan ( Ingrisch 2018) .

Diagnosis: Magnigryllacris can be recognized by the combination of the following characters: ocelli small or invisible; veins of forewings green and cells yellowish brown when alive; veins of hindwings light brown, cells between cross veins brown ( Fig. 8A, B ); posterior margin of male ninth abdominal tergite with spines extending inwards from each lobe at base, length of spines shorter than half the width of ninth abdominal tergite ( Fig. 7F ). Magnigryllacris is similar to Eugryllacris , Radigryllacris , and Prosopogryllacris , but can be distinguished by small or invisible ocelli and centre area of cells on hindwings brown. Eugryllacris also differs from Magnigryllacris by overall transparent hindwings. Prosopogryllacris also differs from Magnigryllacris by a black face (see Table 5 for details).

Description: Body large-sized (25–50 mm. approx.) and stout ( Fig. 9D ); fastigium verticis about twice as wide as scapus; ocelli small or invisible; anterior margin of pronotum slightly roundly projecting, posterior margin straight; macropterous, veins of forewings green and cells yellowish brown when alive; veins of hindwings light brown, cells between cross veins brown ( Fig. 8A, B ); posterior margin of male ninth abdominal tergite with spines extending inwards from each lobe at base, length of spines shorter than half the width of ninth abdominal tergite ( Fig. 7F ); male subgenital plate with styli, posterior margin wide and slightly excised; female ovipositor long and curved upwards, dorsal margin with an expansion before tip.

Etymology: The word ‘magni-’ is derived from the Latin word ‘ magnus ’, meaning huge, and refers to the large size of species in this family.

Remarks: See remarks for Eugryllacris and Table 5 .
