Phyllium boislardi Cumming, Foley, Hennemann, Le Tirant & Büscher sp. nov. Figs 3, 4, 5 Type material. Holotype (♀): Indonesia • N. Kalimantan, Malinau, V. 2021, Local Coll. via Edy Bhaskara; DNA Sample: SLT 030; Coll RC # 21-037 [IMQC]. Paratypes: (1 ♀, 1 egg): (1 ♀) Indonesia • N. Kalimantan, Malinau, III. 2019, Local Coll. via Edy Bhaskara; DNA Sample: SLT 030; Coll RC # 21-036 [Coll RC]; (1 egg) Laid by the holotype female from Indonesia • N. Kalimantan, Malinau, V. 2021, local coll. via Edy Bhaskara, Coll RC # 22-001 [Coll RC]. Differentiation. Male unknown. Female Phyllium boislardi sp. nov. (Fig. 3) are most similar to Phyllium palawanense due to similar femoral lobe shapes / serration and mesoprescutum nodes arranged in a somewhat haphazard way, not exclusively aligned along the sagittal plane. Phyllium boislardi sp. nov. can be differentiated from Phyllium palawanense by the mesopleurae, as Phyllium palawanense has mesopleurae which are marked with more prominent tubercles, vs Phyllium boislardi sp. nov. which has mesopleurae marked with smaller granulation (Fig. 4 B). An additional feature which might also be useful is the ventral coxae coloration as Phyllium boislardi sp. nov. has pale orange coloration (Fig. 3 B) vs Phyllium palawanense which has a pale pink color. Eggs of Phyllium boislardi sp. nov. (Fig. 5) are very similar to Phyllium palawanense eggs with the triangular cross-section and the large feather-like pinnae around the margins and operculum. These species can be differentiated by the differing micropylar plate shape as Phyllium boislardi sp. nov. has a thin, straight sided plate (Fig. 5 D), vs Phyllium palawanense which has a wider, more ovoid plate. Additionally, the bald patches on the lateral walls of the capsule differ slightly, with Phyllium palawanense having longitudinal bald stripes vs Phyllium boislardi sp. nov. which has these longitudinal stripes broken up into subcells (Fig. 5 B). Description. Female. Coloration. Coloration description is based upon images of the living type specimens (Fig. 3). In the holotype and paratype, the general coloration is pale green throughout. In the holotype, these are numerous colored patches across the dorsal and ventral surfaces (Fig. 3 A) while the paratype is simply pale green throughout and lacks these colored patches. In the holotype, there are brown spots of varying sizes and shapes on the legs, abdomen, and tegmina. Ventral coxae coloration is pale orange (Fig. 3 B). Morphology. Head capsule slightly longer than wide, with a dorsal surface that is smooth, lacking granulation (Fig. 4 B). The posteromedial tubercle is present, singularly lobed, but not very prominent (Fig. 4 B). Frontal convexity broad and ending in a blunted point; there are only a few short setae across the surface. Compound eyes small and only slightly protruding from the head capsule, not bulbous, taking up ~ 1 / 5 of the head capsule lateral margins (Fig. 4 B). Ocelli absent. Antennal field approx. as wide as first antennomere. Antennae consist of nine segments (Fig. 4 C), with the terminal segment not particularly wide or long (slightly shorter than the combined length of the previous two segments combined lengths). Antennomeres IX and the distal 1 / 2 of segment VIII have a rough, fuzzy texture with short, dark setae. The remaining segments are smooth, and sparsely marked with short, transparent setae, none prominent (Fig. 4 C). Thorax. Pronotum with slightly concave anterior margin and lateral margins that anteriorly start wide, angle inward strongly towards the posterior margin which is slightly wider than 1 / 2 of the anterior margin width (Fig. 4 B). The pronotum anterior margin has a prominent rim, the lateral margins are less prominent, and the posterior margin is weakly developed. The pronotum surface is relatively smooth, has a small but prominent sagittal slit in the center and another near the anterior. The remainder of the surface is smooth and marked with a few other furrows (Fig. 4 B). Prosternum and the anterior 1 / 2 of the mesosternum are covered throughout by moderately spaced granulation. The posterior 1 / 2 of the mesosternum and the metasternum are relatively smooth (Fig. 4 G). Mesoprescutum slightly longer than wide, lateral rims lumpy with 8–10 variable sized and spaced nodes (3–5 of these are somewhat prominent; Fig. 4 B). Mesoprescutum anterior rim distinctly raised and slightly lumpy but not forming a distinct sagittal spine (Fig. 4 B). Mesoprescutum surface wrinkled and lumpy, mostly just with nodes along the sagittal plane, but there are several prominent nodes spread throughout the surface (Fig. 4 B). Mesopleurae begin to diverge ~ ½ of the way along the mesoprescutum, angle prominently away with straight margins (Fig. 4 B). Mesopleurae lateral margins with five or six small spiniform tubercles with interspersed granulation throughout, giving the margin a roughly textured appearance since none are particularly prominent (Fig. 4 B). Face of the mesopleura slightly wrinkled along the lateral margins, and marked with two notable divots, one on the anterior margin and one near the middle (Fig. 4 B). Wings. Tegmina long, reaching the anterior margin of abdominal segment VIII. Tegmina venation; the subcosta (Sc) is the first vein in the forewing, running parallel with the margin for the first 1 / 2, and then bending and running towards the margin. The subcosta runs for ~ ¼ of the tegmina length. The radius (R) spans the anterior ½ of the forewing with two subparallel branched veins; the first radius (R 1) branches ~ ¼ of the way through the wing length and terminates ~ 2 / 5 of the way through the wing length; the radial sector (Rs) branches ~ 1 / 3 of the way through the wing length and terminates near the distal 3 / 5 of the wing length. There is a weak continuation of the radius following the prominent Rs branching which continues on as a short but distinct R – M crossvein that weakly connects the two veins. The media (M) is bifurcate with both the media anterior (MA) and media posterior (MP) terminating near to the posterior of the tegmina. The cubitus (Cu) is also bifurcate, branching near the posterior ¼ of the wing into the cubitus anterior (CuA) and cubitus posterior (CuP) which both terminate near the wing apex. The first anal vein (1 A) is simple and fuses with the cubitus ~ 1 / 5 of the way through the tegmina length. Alae vestigial nubs. Abdomen. Abdominal segments II through the anterior ½ of IV gradually and uniformly diverging. The posterior ½ of segment IV through the anterior ½ of segment VII are gradually converging. The posterior ½ of segment VII through the apex of the abdomen is converging to a blunted apex. Genitalia. Subgenital plate starts at the anterior margin of tergum VIII, is relatively narrow, and extends half-way onto tergum X. The overall shape is rather narrow, with the apex a blunted point (Fig. 4 F). Gonapophyses VIII are long and narrow, slightly exceeding the apex of abdominal tergum X; gonapophyses IX are mostly obstructed from view (Fig. 4 F). Cerci flat, and somewhat paddle-shaped, with narrow bases broadening out to a wide distal ½ (Fig. 4 F). Legs. Profemoral exterior lobe broad, rounded, arching from end to end, with a width similar to the width of the interior lobe (Fig. 4 D). Margin of profemoral exterior lobe smooth (Fig. 4 D). Profemoral interior lobe ~ 2.5 × as wide as the greatest width of the profemoral shaft, slightly obtusely angled, and marked with several teeth (starting on the proximal end: two large triangular teeth, then a large gap, another large triangular tooth, followed by a smaller finely pointed tooth on the distal end; Fig. 4 D). Mesofemoral exterior lobe approx. a narrow, rounded triangle with the greatest width similar to the mesofemoral shaft width, and the greatest width situated slightly distal to the midlength. Mesofemoral exterior lobe margin smooth, lacking teeth. Mesofemoral interior lobe is approx. the same width as the mesofemoral shaft, with a shape that is gently arching from end to end, with the distal 1 / 2 marked with 6–9 small, serrate teeth. Metafemoral interior lobe narrow on the proximal 1 / 2 with the wider distal 1 / 2 arching to the distal end. The distal 1 / 2 of the metafemoral interior lobe is marked with eight or nine small, serrate teeth. Metafemoral exterior lobe is thin and smooth, hugging the metafemoral shaft and lacks dentation. Protibia lacking an exterior lobe (Fig. 4 D). Protibia interior lobe spans the entire length of the protibia and is ~ 2 × the width of the protibia shaft itself. The lobe is roundly triangular with the widest portion slightly situated slightly distal to the midlength. Mesotibiae and metatibiae simple, lacking exterior and interior lobes. Measurements (mm).
