Type species: Locusta (Gryllacris) borneoensis Haan, 1843 = Borneogryllacris borneoensis (Haan 1843) .

Diagnosis: Borneogryllacris can be recognized by the combination of the following characters: basal areas of forewing with a large, black and yellow spot (Fig. 6F); posterior margin of male ninth abdominal tergite with slender spines extending inwards from the middle of each lobe at base, length of spines equal to or longer than half the width of ninth abdominal tergite (Fig. 7E). Borneogryllacris is similar to Capnogryllacris, Marthogryllacris, Dracogryllacris, and Ultragryllacris, but can be distinguished by the large, black and yellow spot on basal areas of forewings. Capnogryllacris also differs from Borneogryllacris by the black overall fuscous hindwings. Marthogryllacris and Dracogryllacris also differ from Borneogryllacris by the crossed spines on male ninth abdominal tergite. Ultragryllacris differs from Borneogryllacris by the large dorsal projection on male ninth abdominal tergite (see Table 4 for details).
