Duolandrevus gingoogus Otte, 1988: 314 .

Duolandrevus (Bejorama) gingoogus Otte, 1988 — Gorochov, 2016: 27.

Specimen examined. 1♂. PHILIPPINES; Mindanao, Lanao del Norte, Iligan City, Barangay Rogongon, Sitio Lawlawon , Sikyop Agriculture Cooperative ; N8.24550, E124.42183, 327 m .a.s.l.; on fallen branches of Piper aduncum ; March 2, 2025; coll. J. Daguplo; PNM .

Remarks. Our specimen ( Fig. 4 ) from Lanao del Norte belongs to the subgenus Bejorama Otte, 1988 based on the distinct stridulatory apparatus ( Fig. 5D ), an apical bundle of strong setae directed upwards of male anal plate, and lacking a distinct transverse epiphallic fold as well as dorsal denticles on epiphallus ( Fig. 6 ). It is most similar to Duolandrevus (Bejorama) gingoogus Otte, 1988 from Mindanao Island, and differs from Duolandrevus (Bejorama) balabacus Otte,1988 fromPalawanIslandand Duolandrevus (Bejorama) luzonensis Otte, 1988 by slight differences in the metanotal gland, FW venation, and male genitalia (particularly in the shape of the pseudepiphallic lobe [posterolateral epiphallic lobe]) (see Otte, 1988; Gorochov, 2016). This species was previously known from Mt. Pomalith in Misamis Oriental; hence we add a new locality record for this species.

Ecology. The species were found common in the area. Multiple males were heard singing at night underneath a falling logs and branches.

Distribution. PHILIPPINES: Mindanao Island: Misamis Oriental: Mt. Pomalith and Lanao del Norte (Iligan City) [new locality record].

Type locality. PHILIPPINES: Mindanao Island: Misamis Oriental: Mt. Pomalith (N8.658689, E125.192012) .
