New material examined. EAST MALAYSIA • 1♂; Sabah State, Maliau Basin, trail from Agathis–Nepenthes Camps , at 2-km mark; N4.70468 E116.89717, 843.6± 8.5 m.a.s.l.; 12 November 2024, 21h18; walking on forest floor; coll. M.K. Tan; SBH.24.54 ( ZRC) GoogleMaps .

Remarks. Our specimen ( Figs 4G–L View FIGURE 4 ) mostly resembles Macrogryllus ephippium most among the congeners by the shape of the pseudepiphallus (pseudepiphallic lophi in lateral view tapering into a very slender and elongated apex, and posterior margin between the lobes truncated—although that margin of our specimen at middle is also somewhat angular); and the shape of the pseudepiphallic paramere ( Fig. 7 View FIGURE 7 ).

The pseudepiphallic paramere of our specimen resembles that of Macrogryllus ephippium vespertinus from Sumatra in the shape of the apical (medial) sclerite (as) and the relative length of proximal (anterior) portion (ps) with apical (medial) sclerite (as), but resembles that of Macrogryllus ephippium ephippium from Borneo (sensu Gorochov, 2022) by the shape of the mesal lobe (ml) and the posterodorsal sclerite (pds) more robust and stouter.

Distribution (sensu Gorochov [2001, 2022]). Sumatra ( Lampung Province: Bukit Barisan Selatan; West Sumatra: Harau Valley), Borneo ( Sabah State: Maliau Basin [new locality record], Mount Trus Madi; Kalimantan Province: Bukit Bangkirai).

Type locality. “tropical Africa or Java?” (see Gorochov, 2022); INDONESIA: West Sumatra, Harau Valley. National Park (for subspecies Macrogryllus ephippium vespertinus Gorochov, 2001 ).
