Salomona lumadae Tan, Baroga-Barbecho & Yap, 2018

( Figs 4 , 10 )

Salomona lumadae Tan, Baroga-Barbecho & Yap, 2018 in Tan et al., 2018: 342. Type material examined. • ♂ holotype; PHILIPPINES, Mindanao, Surigao del Norte, Siargao Island, Del Carmen, Barangay Katipunan; N9.86082 E126.03313, 59.6± 5.5 m.a.s.l.; 9 April 2018, 00h01; coll. M.K. Tan, H. Yeo, J.B. Baroga-Barbecho, S.A. Yap; Siargao18_35 (UPLBMNH).

New material examined. • 1♂; PHILIPPINES, Mindanao, Surigao del Sur, Lanuza, Barangay Agsam ; N9.1033 E126.319, 360 m .a.s.l.; 2 September 2024, 06h54; coll. K. Grumo; Sitio Himatagan 11 ( ZRC) .

Additional description. Titillators ( Figs 4E–G ) separate; bases curved slightly laterad, otherwise simply long-lamellar; in lateral view scythe-shaped; apical extensions with small rounded anterior lobe, with posterior end elongated, tapering and faintly sinuous; apex slightly curved dorsad, appeared hooked dorsad.

Comparison. Salomona lumadae resembles congeners from both Borneo and New Guinea. It is similar to Salomona borneensis Willemse, 1959 from Borneo ( Ingrisch, 1998; Tan et al., 2024) in the lateral field of the tegmen having black cells and the abdominal appendages (its tenth abdominal tergite with the apical margin excised at the middle and produced on both sides into a rounded lobe; its cercus cylindrical, faintly curved with the internal process at circa half of the cercus length); but differs by the male cercus at its apex subacute instead of terminating in an acute ventral spine and the shape of the titillators.

In addition to the comparisons already made in Tan et al. (2018), S. lumadae resembles Salomona godeffroyi (Pictet, 1888) from New Guinea by the general habitus and the male cercus; but differs by its tenth abdominal tergite with the apical margin clearly excised at the middle and produced on both sides into a small rounded lobe, the cercus less elongated or cylindrical, and the subgenital plate narrower apically with shorter styli. It is also similar to Salomona ustulata Redtenbacher, 1891 from New Guinea by the shape of the cercus and its internal process; but differs by the colour patterns (without black margins on the pronotum and black patches on the femora, mesosternal and metasternal lobes; but its lateral field with cells black) and the cercus more triangular than cylindrical.

Salomona lumadae is also similar to Salomona notata Willemse, 1959 from New Guinea by the shape of the tenth abdominal tergites (with two lateral spots) and the shape of the cercus; but differs by the cercus slenderer and the internal process not triangular, the styli shorter and not widely separated by a truncated and broad emargination at the posterior margin of the subgenital plate, and the frons without a thick black longitudinal band. It is similar to Salomona sculptile Willemse, 1959 from New Guinea by the shape of the male cercus; but differs by the internal process larger and apex more acute and the subgenital plate not triangularly and deeply excised at the apex with shorter styli.

It is similar to Salomona saussurei Brongniart, 1897 from Fiji by the shapes of the tenth abdominal tergite and cercus; but differs by the cercus with only one (instead of two) internal process. It also differs from Salomona extrema Willemse, 1959 from North Sumatra (closely resembling S. borneensis and potentially synonyms [ Ingrisch, 1998]) by its cercus slightly curved (instead of straight) with less acute apex.

Type locality. PHILIPPINES, Mindanao, Surigao del Norte, Siargao Island .

Distribution. PHILIPPINES (Mindanao: Siargao Island, Surigao del Sur [new locality record]) ( Fig. 10 ).

Natural history. This species was observed to be active at night, especially after rainfall. This is not different from the observations made in Siargao Island.
