Key to the species of Rhagovelia View in CoL in the Palawan region
1. Anterior margin of pronotum entirely yellowish; connexival margin yellowish ( Figs. 5A–D View Fig , 6A–C View Fig ). Pronotum of apterous morph much longer than eye length, with strongly convex hind margin, covering most of mesonotum (e.g., Fig. 5A View Fig ). Forewing blackish with light streak at base (e.g., Fig. 5C View Fig ). Body length 2.8–3.9 mm. (III. R. papuensis View in CoL group) ...................................2
– Pronotum black, with short orange or yellowish mark anteriorly; connexival margin black ( Figs. 1A–D View Fig , 2A–D View Fig , 3A–F View Fig , 4A–C View Fig ). Pronotum of apterous morph shorter than eye length, with straight hind margin; mesonotum largely exposed (e.g., Fig. 1A View Fig ). Forewing without light streak at base (e.g., Figs. 3F View Fig , 4C View Fig ). Body length 1.9–2.9 mm, except 3.3–3.5 mm in the females of R. lansburyi View in CoL .........................................................................3
2. Anterior part of head black (not in freshly moulted specimens). Tergites 7 and 8 without shiny areas. Juga (pair of plates at sides of labrum and rostrum base) with small black spinulae. Paramere of male distally broad, truncate ( Fig. 7G View Fig ). Apterous female with connexival margins widely separated all over length ( Fig. 5B View Fig ). Common and widespread in the region, also on Borneo ........................................ R. kawakamii hoberlandti View in CoL
– Anterior part of head (in frontal view) usually pale orange to brown, rarely blackish. Juga without spinulae. Apterous specimens with shiny areas on tergites 7 and 8 (more distinct in female). Paramere of male distally slender, with small ventrally directed lobe ( Fig. 7H View Fig ). Connexival margin of apterous female strongly convergent near apex ( Figs. 6B View Fig , 10G View Fig ). Widespread in the region............................................. R. gapudi , new species
3. Stout species, strongly dimorphic; female much larger than male, in apterous morph 3.03–3.34 mm vs. 2.34–2.63 mm. Male with modified foreleg ( Fig. 4A View Fig ), protibia with distinct bend at distal fourth. In male, dentition of metafemur reduced; in female, metafemur without dentition ( Fig. 4B View Fig ). (II. R. lansburyi View in CoL group)..................................................................... R. lansburyi View in CoL
– Usually slender; if stout, then much smaller. Body length 1.9–2.6 mm. Foreleg of males not modified, protibia more or less straight. In males, dentition of metafemur prominent (e.g., Fig. 9A, C, D View Fig ); in female reduced, but always present (e.g., Fig. 9B, E View Fig ). (II. R. sarawakensis View in CoL group) ................................4
4. Abdomen without spike-like setae. Sternites 3–6 (7) of male with sharp median carina. Mesofemur of female with short patch of long setae at depression on distal third....................5
– Connexiva (and in apterous specimens also anterior tergites) with numerous short and stout, spike-like setae ( Fig. 10A View Fig ). Sternites 3–5 of male without sharp median carina (a very obtuse carina present in R. palawanensis View in CoL ). Mesofemur of female with brush of long setae in distal half ......................................................6
5. Very stout species ( Fig. 3C, E View Fig ); in female, abdomen strongly shortened, upcurved in apterous morph. In male, median carina on sternite 7 reduced, weaker than on sternites 3–6. Species from North Palawan ...................... R. abbreviata , new species – Species of normal shape ( Fig. 3A, B View Fig ). Abdomen of female not shortened. In male, median carina on sternite 7 prominent, accentuated by paired impressions, stronger than on sternites 2–6. Species from Central Palawan ......................... R. estrella View in CoL
6. Mesocoxa, mesotrochanter, and metafemur entirely black ( Fig. 1C, D View Fig ). Species from South and Central Palawan ................... ........................................................................ R. palawanensis View in CoL
– Mesocoxa, base of mesotrochanter, and base of metafemur yellow ( Figs. 1A, B View Fig , 2A–D View Fig ) ...................................................7
7. Spike-like setae sparse, in apterous male scattered from mesonotum to tergite 5, in apterous female until tergite 2, rarely forming a transverse row on tergite 1. Segment 8 of male ventrally convex. Apterous female without distinct constriction at base of sternite 7. Female without distinct hair tuft on connexival corner. Species from Busuanga Island...... ........................................................................... R. minutissima View in CoL
– Spike-like setae numerous, in apterous male from mesonotum to tergite 7, in apterous female until tergite 4, with distinct transverse row on tergite 1. Segment 8 of male ventrally flat. Apterous female with strong constriction at base of sternite 7. Female with distinct tuft of black hairs at connexival corner ( Fig. 10A View Fig ; indistinct in some macropterous individuals). Species from North Palawan ....................... R. matillanoi , new species
