description: Key to the genera of Indo-Pacific Serolidae Since the publication of Brandt’s (1988) review there has been a proliferation of genera within the Serolidae. Prior to that date five genera were recognised; the publication of six new genera by Wägele (1994) brought the total to 20 genera. Th e most recent key, to any region, is that of Brandt (1988), and that work no longer reflects the generic composition of the family. Th e key provided here is intended only to operate for the genera known to occur in the Indo-Pacific, the region bounded by East Africa in the west, eastwards to Hawai’i and the island nations of Oceania (e.g. see Briggs 1974). Th e key also serves to emphasize the character states now in use in defining genera. 1 Uropods on posterolateral angle of pleotelson, uropods and pleonites forming part of continuous body outline........ <b> <i>Thysanoserolis</i> Brandt, 1991</b> – Uropods mediolateral or anterolateral, not forming part of body outline.... <b>2</b> 2 Pleonites not extending posteriorly along pleotelson lateral margins; pleopod 2 endopod with distal stem; uropods greater than three-quarters length of pleotelson................................................................................................... <b>3</b> – Pleonites extending posteriorly along pleotelson lateral margins; pleopod 2 endopod without distal stem; uropods less than half length of pleotelson... <b>5</b> 3 Pereonites 5–7 entire, with sutures distinct; pleotelson posterior margin broad, flat and truncate; uropodal mesial margin positioned in dorsal groove on pleotelson lateral margin............................................... <b> <i>Sedorolis</i> gen. n.</b> – Pereonites 5–7 medially fused; pleotelson posterior margin narrowly rounded or truncate; uropodal mesial margin positioned ventrally on pleotelson lateral margin........................................................................................................ <b>4</b> 4 Pleonite sternal plate 1 with prominent process; pleotelson posterior margin narrow, excavate or indented............................. <b> <i>Heteroserolis</i> Brandt, 1991</b> – Pleonite sternal plate 1 without prominent process; pleotelson posterior margin narrowly rounded................................................. <b> <i>Serolina</i> Poore, 1987</b> 5 Coxae distally acute, those of pereonite 6 narrow, elongate, greatly extended posteriorly beyond pleotelson and pleonites; pleonites extending beyond pleotelson posterior margin......................... <b> <i>Brucerolis</i> Poore &amp; Storey, 2009</b> <b> 1</b> – Coxae quadrate, not narrowed or greatly extended; pleonites extending along but not beyond pleotelson margin.............................................................. <b>6</b> 6 Coxae 6 overlapping and extending posterior to pleonites; antennal peduncle articles 4 and 5 slender (8.6–10.3 × as long as greatest width); uropods ventrolateral, inconspicuous in dorsal view........................... <b> <i>Myopiarolis</i> gen. n.</b> 1 Poore and Storey (2009) have redefined <i>Acutiserolis</i> and those species from the southwestern Pacific and New Zealand hitherto placed in that genus, notably <i>Acutiserolis cidaris</i> Poore &amp; Brandt, 1977 from the Coral Sea, have been placed in <i>Brucerolis</i> (see Poore and Storey 2009 this issue; Storey and Poore 2009 in press). – Coxae 6 overlapping but not extending posteriorly beyond pleonites; antennal peduncle articles 4 and 5 broad (&lt;5 × as long as greatest width); uropods lateral, conspicuous in dorsal view........ <b> <i>Caecoserolis</i> Wägele, 1994</b>
