Table 1 in Establishment of a new shrimp family Chlorotocellidae for four genera previously assigned to Pandalidae (Decapoda, Caridea, Pandaloidea)

Table 1. Comparison of diagnostic characters between Chlorotocellidae fam. nov. and Pandalidae. Character states of Chlorotocellidae are apomorphic against those of Pandalidae.
Chlorotocellidae fam. nov.Pandalidae1Rostrum, if present, without teeth or fringe of setae on ventral margin (Figs 1A, 4A).Rostrum usually well developed, ventral margin armed with a few or series of teeth accompanied by row(s) of short setae.2Thoracic sternites without conspicuous ornamentation, such as keels, teeth or protuberances (Fig. 3B).Thoracic sternites 6 and 7 each with paired prominences on either side of median keel; thoracic sternite 8 with transverse carina bearing submedian spines or teeth (Fig. 3A).3Pleomere 6 without posteroventral tooth; posterolateral process rounded or truncate (Figs 1C, 4B).Pleomere 6 with small posteroventral tooth; posterolateral process terminating in small tooth.4Telson with dorsolateral spiniform setae located adjacent to lateral margins (Figs 1D, 4C).Telson with dorsolateral spiniform setae located on dorsolateral ridges.5Eyestalks subcylindrical, cornea distinctly shorter than eyestalk (Figs 1E, 4D).Eyestalks pyriform or subpyriform, cornea distinctly wider than eyestalk.6Antennular stylocerite distally obliquely truncate, bi- or tri-dentate, devoid of proximolateral projection (1F, 4E).Antennular stylocerite acuminate or rounded, usually having small proximolateral projection (Fig. 6A).7Outer antennular flagellum with distal portion (distal to thickened aesthetasc-bearing portion) reduced, consisting of few articles (Figs 1A, 4E).Outer antennular flagellum with distal portion (distal to aesthetasc-bearing portion) long and slender, consisting of 10 or more articles.8Maxilliped 2 without podobranch (Fig. 1L).Maxilliped 2 with podobranch.9Maxilliped 3 without exopod (Figs 2A, 5A).Maxilliped 3 with or without exopod.10Pereopod 1 fingers absent (Figs 2B, 5B, C).Pereopod 1 fingers minute or completely reduced.11Pereopods 2 always subequal; basis without small process on lateral surface of basis; carpus consistently divided into 3 articles (Figs 2C, 5D, 6D).Pereopods 2 subequal or unequal; basis without small process on lateral surface of basis; division of carpus highly variable, but never 3-articulated.12Arthrobranchs absent from maxilliped 3 and pereopods.Arthrobranchs usually present on maxilliped 3 and pereopods 1-4.
