otoidea on <strong>the</strong> recommendation <strong>of</strong> L. Holthuis<br />

(1993a:87, and pers. comm.).<br />

Superfamily Palaemonoidea<br />

The family Euryrhynchidae Holthuis, 1950, was<br />

added on <strong>the</strong> recommendation <strong>of</strong> Holthuis (pers.<br />

comm.). The family Kakaducarididae was described<br />

by A. J. Bruce (1993) as a subfamily <strong>of</strong> <strong>the</strong><br />

Palaeomonidae and is here treated as a family on<br />

<strong>the</strong> recommendation <strong>of</strong> L. Holthuis (pers. comm.).<br />

Superfamily Alpheoidea<br />

Authorship <strong>of</strong> <strong>the</strong> family Ogyrididae remains credited<br />

to Holthuis (1955). Although Hay and Shore<br />

(1918) established <strong>the</strong> family Ogyridae, as noted by<br />

M. Tavares (pers. comm.), L. Holthuis (pers.<br />

comm.) points out that <strong>the</strong>y based it on <strong>the</strong> type<br />

genus Ogyris Stimpson, 1860, which is a junior<br />

homonym <strong>of</strong> Ogyris Westwood and is thus invalid.<br />

Stebbing (1914) proposed <strong>the</strong> replacement genus<br />

Ogyrides, and thus <strong>the</strong> family name is Ogyrididae,<br />

first used as such by Holthuis (1955). We have not<br />

followed Christ<strong>of</strong>fersen’s (1987) suggestion to<br />

transfer <strong>the</strong> family Processidae to <strong>the</strong> Crangonoidea<br />

or to combine <strong>the</strong> alpheoids and crangonoids and<br />

pandaloids into one monophyletic taxon. Christ<strong>of</strong>fersen<br />

(1987) also proposed <strong>the</strong> new alpheoid families<br />

Nauticarididae (to contain Nauticaris and Saron),<br />

Alopidae (to contain Chorismus, Alope, and<br />

Caridion), and Bythocarididae (to contain Bythocaris,<br />

Cryptocheles, and Bathyhippolyte). We have<br />

not followed <strong>the</strong>se suggestions, nor have we recognized<br />

<strong>the</strong> families Merhippolytidae and Thoridae<br />

recognized by Christ<strong>of</strong>fersen (e.g., Christ<strong>of</strong>fersen<br />

1998).<br />

Christ<strong>of</strong>fersen later (1987) also suggested <strong>the</strong> recognition<br />

<strong>of</strong> <strong>the</strong> family Barbouridae (spelling corrected<br />

to Barbouriidae by Christ<strong>of</strong>fersen, 1990), to<br />

include <strong>the</strong> genera Barbouria, Janicea, and Parhippolyte.<br />

In his review <strong>of</strong> caridean shrimps <strong>of</strong> <strong>the</strong> Albatross<br />

Philippine Expedition, Chace (1997), although<br />

finding ‘‘no clear evidence to support <strong>the</strong><br />

superfamilial categories suggested by Christ<strong>of</strong>fersen<br />

(1987),’’ found ‘‘considerable reason to endorse his<br />

[Christ<strong>of</strong>fersen’s] establishment <strong>of</strong> <strong>the</strong> Barbouriidae.’’<br />

Chace refrained from treating <strong>the</strong>se genera<br />

as Barbouriidae in that paper, but we have taken<br />

that step here and recognize <strong>the</strong> Barbouriidae. Inclusion<br />

<strong>of</strong> <strong>the</strong> family in <strong>the</strong> superfamily Alpheoida<br />

is because <strong>of</strong> <strong>the</strong> similarities to hippolytids (all three<br />

genera were formerly treated as members <strong>of</strong> <strong>the</strong><br />

Hippolytidae).<br />

Superfamily Crangonoidea<br />

As noted above, Christ<strong>of</strong>fersen (1987) proposed <strong>the</strong><br />

family Barbouriidae for <strong>the</strong> genera Barbouria, Janicea,<br />

and Parhippolyte and originally placed <strong>the</strong><br />

family in <strong>the</strong> superfamily Crangonoidea. We treat<br />

it here as a member <strong>of</strong> <strong>the</strong> Alpheoidea because <strong>of</strong><br />

<strong>the</strong> similarities to <strong>the</strong> alpheoid family Hippolytidae<br />

(see Chace, 1997:40).<br />

Superfamily Pandaloidea<br />

Christ<strong>of</strong>fersen (1989) suggested a new classification<br />

<strong>of</strong> this superfamily, wherein he proposed many significant<br />

changes. Three new families were proposed<br />

(Plesionikidae for <strong>the</strong> genus Plesionika, Heterocarpoididae<br />

for <strong>the</strong> genus Heterocarpoides, and Dorodoteidae<br />

for <strong>the</strong> genus Dorodotes). In addition,<br />

<strong>the</strong> family Physetocarididae was removed from its<br />

own superfamily and placed in <strong>the</strong> Pandaloidea,<br />

and <strong>the</strong> family Heterocarpidae was recognized. No<br />

diagnoses <strong>of</strong> <strong>the</strong> new taxa were provided (although<br />

character states were given), and we have opted to<br />

not recognize <strong>the</strong>se changes for now.<br />

INFRAORDER ASTACIDEA<br />

Although we are not recognizing <strong>the</strong> ‘‘Macrura<br />

Reptantia’’ as a suborder (see above), for <strong>the</strong> most<br />

part, we have followed <strong>the</strong> admittedly conservative<br />

classification <strong>of</strong> Holthuis (1991) for <strong>the</strong> superfamilies<br />

and families <strong>of</strong> <strong>the</strong> Astacidea (see also Williams,<br />

1988, for classification <strong>of</strong> commercially important<br />

lobster families). Holthuis, who was at <strong>the</strong><br />

time dealing only with <strong>the</strong> marine lobsters and so<br />

did not include <strong>the</strong> parastacoids and astacoids,<br />

treated marine astacideans as belonging to a single<br />

superfamily Nephropoidea containing two families,<br />

Thaumastochelidae and Nephropidae. Our classification<br />

differs only in <strong>the</strong> inclusion <strong>of</strong> <strong>the</strong> Enoplometopoidea<br />

(see below) and Gylpheoidea, <strong>the</strong> latter<br />

placed by Holthuis among <strong>the</strong> infraorder Palinura<br />

(his Palinuridea). Scholtz (1999) recently reviewed<br />

<strong>the</strong> freshwater crayfishes (Astacoidea and Parastacoidea)<br />

and argued that <strong>the</strong>y are members <strong>of</strong> a distinct<br />

clade, Astacida, that is not closely related to<br />

clawed lobsters. However, strong molecular evidence<br />

suggests that clawed lobsters are indeed <strong>the</strong><br />

sister group to <strong>the</strong> astacids (Crandall et al., 2000).<br />

Superfamily Glypheoidea<br />

The primitive family Glypheidae (<strong>the</strong> only extant<br />

family in <strong>the</strong> Glypheoidea) has been transferred to<br />

<strong>the</strong> Astacidea as per <strong>the</strong> recommendations <strong>of</strong> Forest<br />

and Saint Laurent (1989). The taxon name, credited<br />

to Zittel in Bowman and Abele (1982), has<br />

now been credited to <strong>the</strong> earlier usage by Winckler<br />

(M. Hendrickx, pers. comm.), following <strong>the</strong> usage<br />

in Glaessner (1969).<br />

Superfamily Enoplometopoidea<br />

The genus Enoplometopus was assigned its own superfamily<br />

and family (Enoplometopoidea, Enoplometopidae)<br />

by Saint Laurent (1988).<br />

Superfamily Nephropoidea<br />

Tshudy and Babcock (1997) examined fossil and<br />

extant clawed lobsters and indicated that <strong>the</strong> family<br />

Thaumastochelidae, at least as used previously,<br />

may be paraphyletic. We have not taken <strong>the</strong> extra<br />

step <strong>of</strong> deleting this family (which would result in<br />
