description: Key to species of Reticulaphis (based on apterous adult females from Taiwan)
1. Marginal setae with distinctly acute apices.................................................................................................2
-. Marginal setae with blunt, serrated, or fan-shape apices, or not obvious....................................................3
2. Body nearly round; setae on central axis of dorsal prosoma stout; chaetotaxy - 2 setae between eyes, 2 (sometimes 3) setae on pronotum, 2 (sometimes 3) setae on mesonotum, 2 setae on metanotum, 2 setae on abdominal tergite I; pleural regions of prosoma often distinctly expanded .................................. R. distylii
-. Body elliptical; setae on central axis of dorsal prosoma fine; chaetotaxy - 3 or 4 setae between eyes, 3 or 4 setae on pronotum, 4–6 setae on mesonotum, 3–5 setae on metanotum, 2–4 setae on abdominal tergite I; pleural regions of prosoma not expanded ............................................................................................ R. fici
3. Marginal setae stout with blunt apices; 2 thick, blunt apical dorsal setae between eyes, almost as long as marginal setae ............................................................................................................................. R. mirabilis
-. Marginal setae with blunt, frayed, serrated, or fan-shape apices; dorsal setae between eyes fine, not obvious, distinctly shorter than marginal setae.................................................................................................. 4
4. Body ovate with 4 well-defined swellings, or body elliptical with long, thick, strongly curved marginal
setae; marginal setae with acute, blunt, or frayed apices.............................................................................5 -. Body ovate without such swellings, or body elliptical without obvious marginal setae; marginal setae usually with fan-shaped or serrated apices........................................................................................................6
5. Body ovate; prosoma with 4 well-defined swellings, largest one semi-oval, corresponding to position head+prothorax, median to meso- and metathorax, smallest to abdominal tergite I (sometimes swellings indistinct); marginal setae with acute or blunt apices, somewhat curved to rear ................. R. inflata sp. n.
-. Body elliptical; prosoma without above-described swellings; marginal setae long, thick, usually strongly curved to rear, with blunt or frayed apices .............................................................................. R. foveolatae
6. Body elliptical, length nearly twice as long as wide; pleural regions of prosoma very strongly expanded and produced; middle and hind legs distinctly visible from above; marginal setae not obvious .................. .............................................................................................................................................. R. asymmetrica
-. Prosoma without expanded pleural regions, middle legs concealed under prosoma; marginal setae apparent, with serrated or fan-shaped apices........................................................................................................7
7. Prosoma with 2 shrunken furrows at positions corresponding to front and middle legs; abdominal tergite VIII with 2 stout setae, nearly as long as marginal setae ..................................................... R. septica sp. n.
-. Prosoma broadly oval, no shrunken furrows; abdominal tergite VIII with 4 fine setae, obviously shorter than marginal setae ....................................................................................................................... R. rotifera
