Diagnosis

General shape close to M. flammarubra Crispolon & Soulier-Perkins gen. et sp. nov., but the colour pattern distinguishes it immediately. This species is yellowish-brown in colour, while M. flammarubra is red.

Etymology

The species name refers to the tribe ‘Kalanguya’ inhabiting the area where the type specimens were collected. It is treated as a noun in apposition.

Description

Body length 6–7 mm (tegmina included), width 3–3.5 mm.

HEAD (Fig. 2C). Head including eyes, narrower than widest part of pronotum. In dorsal view, eyes slightly elongated, small ocelli, distance between eyes 9 × ocellus diameter, distance between ocelli equals one ocellar diameter, distance between ocellus and compound eye 3 × ocellus diameter, ocelli closer to each other than to compound eyes. Eyes not prominent, 2 × as long as wide. Vertex and frons longitudinal median carina present. Vertex slightly longer than wide with 3 × ocellus diameter in between two vertex grooves outside ocelli and 4 × ocellus diameter between anterior and posterior vertex margins. No dimple in upper part of postclypeus just below frons (as in Amberana). Postclypeus with longitudinal furrow forming two prominent parallel longitudinal carinae, slightly swollen, ovoid shape in frontal view, widest part at mid-height (Fig. 2B), not receding prior to anteclypleus where it bends forming obtuse triangle in lateral view (Fig. 2A). Rostrum very long reaching but not surpassing metacoxae.

THORAX. In dorsal view, pronotum with anterior concavities on each side, anterior margin of pronotum as wide as posterior margin of head including eyes, anterolateral margins curved, posterior margin grooved, posterolateral margins slightly concave and longer than anterolateral margin, humeral angle rounded. Pronotum angle in lateral view around 45° (Fig. 2A). Scutellum slightly longer than wide with large median concavity.

TEGMEN. R bifurcates on apical half, M bifurcates on basal third, veins not thickened on first ⅔, become thickened on apical third, forming concave apical cells (Fig. 2C).

POSTERIOR WING. Rp separating from SC+RA nearly at midlength, r-m absent, M reaches ambient vein, CuA and CuP fused at base, CuA bifurcate in CuA1 and CuA2 at apical third, m-cu links M to CuA above CuA bifurcation, total of six longitudinal veins and five apical cells between SC+RA and CuP, angular protrusion of the costal margin near base present (Fig. 3B).

LEGS. Metafemur with apical spine on inner margin, metatibia bearing 1 lateral spine, both primary and secondary basitarsi with one row of at least five spines.

MALE TERMINALIA. In lateral view, posterior margin of pygofer (Fig. 2E) convex medially with slight curvature towards last third. Subgenital plates (Fig. 2E–F) finger-shaped, with equal length relative to height of pygofer without longated, thin apical appendage extension (as in Mioscarta), ventral and dorsal margins regularly rounded, apex of dorsal margin dented, sterno-lateral plate present and slightly elongated with apical end of dorsal margin pointed, intermediate plates present, roughly Y-shaped, linking internal sides of sterno-lateral plate and subgenital plate. Paramere (Fig. 2G), dorsal margin slightly convex ⅔ of its length then becoming concave before finishing up with spiniform process directed dorsally, ventral margin convex and apex with one larger and two minute spiniform processes directed antero-ventrally. Aedeagus (Fig. 2H), basal third of dorsal margin slightly bent and last ⅔ vertical and S-shaped, basal part of the erected part of aedeagus slightly enlarged, apical extension (ae) directed ventrally, posterior protrusion (pp) elongated directed dorsally, when viewed posteriorly, sub apex flattened, apical part with fine long appendages (Fig. 2I).

COLOUR. Body covered with golden yellow setae. Head, thorax, rostrum, antennal scape, pedicel, tegmen, legs yellowish brown, tegmen apical part much lighter and translucent.

Type locality

Philippines: Luzon, Pangasinan, San Nicolas.

Distribution

Philippines: Luzon Island (Fig. 5).

Molecular phylogeny

The result of the ML analysis with a likelihood score of -18712.403 is shown in Figure 4. In the phylogeny, the ingroup appears as monophyletic, supported by an ML bootstrap value (ML BS) of 98.1/98% (SH-aLRT support/standard bootstrap support). Miosterpa Crsipolon & Yap gen. nov. is recovered as a monophyletic group which is supported by an ML BS of 64.3/88%. Is recovered as sister group of Poeciloterpa supported by an ML BS of 97.2/98%. The genera Mioscarta and Trigonoschema, each represented in the phylogeny by only one specimen, are recovered together as monophyletic with an ML BS of 46.6/67%. These four closely related genera: (( Mioscarta + Trigonoschema)+(Miosterpa + Poeciloterpa )), form a clade, supported by an ML BS of 89/81%.

For the other genera used as ingroup here, the relationships recovered corroborate the work of Crispolon et al. (2023), even with the much smaller number of terminals used in this study. The clade (Wawi + (Aufidus + (Euryaulax + (Phantagma + (Jacobsoniella + Vinpietri ))))) was recovered as sister to (( Trigonoschema + Mioscarta) + (Miosterpa Crsipolon & Yap gen. nov. + Poeciloterpa )), and the clade (Eoscarta + (Callitettix + (Sounama + Kanozata ))) is sister to this clade. While the clade (Paraliterna sp. + Colsa costaestriga) was recovered at the base of the ingroup.
