Key to species of Anaspides
1 Telson posterior margin with 4–10 (rarely 15), stout, well-spaced spines ......................................................................................................................................... 2
—— Telson posterior margin lined with more than 17 (usually> 20), slender, finely-spaced spines ..................................................................................................... 3
2 Telson about as long as wide, posterior marginal spines limited to posterior one-fourth. Pleonite 6 posterior margin and pleura 4–5 unarmed. Adult male with 4 (rarely 5) antennular clasping spines. Pleopods 4–5 (usually 3–5) without endopod .......................... A. clarkei Ahyong, 2015
—— Telson distinctly longer than wide, posterior marginal spines limited to posterior one-third. Pleonite 6 posterior margin denticulate; pleura usually with 1 or more small spines. Adult male with 1 antennular clasping spine. Pleopods 3–4 with endopod ...................................................................................... A. eberhardi sp. nov.
3 Adult males with 1 antennular clasping spine ........................................ A. richardsoni sp. nov.
—— Adult males with 2 or more antennular clasping spines ............................................................ 5
4 Telson linguiform, elongate, lateral margins seamlessly grading into evenly rounded, posterior margin ...................................... A. tasmaniae ( Thomson, 1893)
—— Telson polygonal, transition between lateral and posterior margins obtusely angular, blunt; posterior margin angular to rounded ...................................................................................................................................... 5
5 Adult males with 2 antennular clasping spines. Male pleopod 1 endopod with retinacular lobe visible in lateral view ................................................................ 6
—— Adult males with 3–5 (usually 4) antennular clasping spines. Male pleopod 1 endopod with retinacular lobe obscured, not visible in lateral view ......................................................................... A. jarmani Ahyong, 2015
6 Pleonite 6 posterolateral margins blunt, rounded, at most with a minute spinule. Pleonites 5–6 with or without short spines on posterior tergal margins, usually absent on tergite 5; pleura 3–5 with or without small spines, usually absent or at most 1 or 2 small spines on pleura 4–5 ................................................................ A. swaini Ahyong, 2015
—— Pleonite 6 posterolateral margins produced to prominent spine. Pleonites 5–6 with prominent spination on posterior tergal margins, spines distinctly longer than wide; pleura 3–5 prominently spinose .......................................................................
