MATERIAL. Holotype – ♂, Philippines: Mindanao I., ~ 150 km NNW of Dabaw City, environs of Dahilayan Adventure Park (8º11ʹ38ʹʹ N, 124º51ʹ39ʹʹ E), 1000–1500 m, primary/secondary forest, at light, 2–9.II 2024, A. Gorochov , M. Omelko, I. Naumenko ( ZIN). Paratypes: 3 ♂, same data as for holotype ( ZIN) GoogleMaps .

DESCRIPTION. Male (holotype). Coloration and structure of body more or less similar to those of Ph. javanica sp. n., Ph. spinulenta sp. n. and Ph. tapienomima sp. n. but with following characteristic features: body slightly smaller (see measurements); integument more or less matte, but head (except for epicranial dorsum), legs, wings and last tergite as well as distal halves of cerci somewhat shining; coloration yellowish with a pair of short rose lines on proximal half of upper rostral tubercle above lateral ocelli, rose to light brown tympanal area in each fore tibia but with dark brown short dorsal longitudinal stripe between tympana, dark brown cell membranes in narrow part of each dorsal tegminal field (behind stridulatory apparatus) and one row of small cell membranes in each lateral tegminal field very near dark membranes of dorsal field ( Figs 51, 52 View Figs 49–54 , 57 View Figs 55–60 ), transparent some wing membranes (as in these species), brown to brownish dots on some abdominal tergites, and blackish apical parts of cerci ( Figs 65–67 View Figs 61–72 ); pronotum more similar to that of Ph. javanica sp. n. and Ph. spinulenta sp. n. in shape but shorter than in Ph. tapienomima sp. n. ( Fig. 51 View Figs 49–54 ); tegmina with branches of R more similar to those of Ph. javanica sp. n. than to those of Ph. spinulenta sp. n. and Ph. tapienomima sp. n. ( Fig. 52 View Figs 49–54 ), and with stridulatory apparatus as in Figs 57, 58 View Figs 55–60 ; last tergite with moderately short and very wide posteromedian process (this process flattened dorsoventrally, with median lobe widest and longest but roundly obtuse-angled posteriorly, and with lateral lobes somewhat smaller and rounded as well as almost horizontally lamellar; Figs 65, 67 View Figs 61–72 ); cercus mostly straight and with distinct dorsal tubercle near strongly curved distal portion which almost straight and spine-like but directed medially ( Figs 65–67 View Figs 61–72 ); genital plate as in Figs 66, 67 View Figs 61–72 .

Variations. One paratype with numerous and very small (poorly distinct) rose to brownish dots on pronotum and all femora; posterior edge of median lobe of last tergite posteromedian process varied from almost obtuse-angled to sinuate (i.e., with three very short lobules posteriorly); genital plate also varied from that with distinct posteromedian notch to that with almost truncated apex.

Female unknown.

Length (in mm). Body 15–18; body with wings 36–38; pronotum 4.7–4.9; tegmina 28–29; hind femora 15.5–16.

COMPARISON. The new species belongs to the third tentative group (with diverse male abdominal apices) and differs from Ph. luzonica (from Luzon I.) and Ph. phaneropteroides (also from Luzon I.) in a larger (longer) process of the male last tergite and a distinctly less widened distal part of the male cercus. From Ph. galeata (from Mindanao I.), the new species is distinguished by this tergal process clearly less high in the profile, and the male cercus with a distinct dorsal tubercle in the subapical part; from Ph. neglecta (from Sulawesi I.) and Ph. compressa (from Key I.), by the aforementioned process clearly wider and with a roundly angular posteromedian part (vs this process is distally bilobed or truncated); from all other true and probable congeners, by the following combination of characters: the process of the male last tergite is distinctly wider, the male cercus has a distinct dorsal tubercle in the subapical part, the body size is clearly smaller (approximately as in Ph. spinulenta sp. n.), and the pronotum is distinctly longer (lengths of pronotum, tegmina and hind femur are about 5, 30, 15.5 mm in the new species and about 4.3, 31, 15.7 mm in Ph. reticulata , respectively).
