From Mt Ginini, one of the occurrences of this species.
Diagnosis. P

cammooensis
by three (versus four or five) teeth on dental margin of maxillipede; numerous (up to 26) setae scattered over first genital sternite of female.

Discussion.
Paralamyctes
(
Haasiella
)
ginini
is identical to
P
.
(
H
.)
cammooensis
in most respects. The two species have the same tergite shapes (figures 2, 3 versus 13), size and position of the Tömösváry organ (figures 6A, 16H), form of the mandibular aciculae (figures 5G, 16G), shape of the female gonopod spurs (figures 5I, 16F), distal spinose projections confined to the tibiae of legs 1–12, and both species are relatively small [maximum body length 8.4 mm in
P
.
(
H
.)
ginini
]. Seven of nine specimens of
P
.
(
H
.)
ginini
have 3+3 teeth on the dental margin of the maxillipede (figure 16D), the others having 3+4, whereas large specimens from
Queensland
have 4+4, 4+5
/
5+4, 5+5 or, exceptionally, 6+6 teeth (figure 4B–F). Juvenile specimens of
P
.
(
H
.)
cammooensis
with 3+3 teeth (several in ANIC-03-14) have less-developed gonopods than do the larger specimens of
P
.
(
H
.)
ginini
(e.g. female gonopod lacking spurs). Males of
P
.
(
H
.)
ginini
have a single round coxal pore on legs 12–15 (figure 15) except for one large specimen with 1,2,2,2
/
1,2,2,2; the coxal pore arrangement in females is consistently 2,2,2,2
/
2,2,2,2. All specimens have 17+17 antennal articles except for a juvenile with 16
/
16 and one specimen with 17
/
18. Setation of the first genital sternite of females distinguishes the species:
P
.
(
H
.)
ginini
has more numerous setae scattered on the sternite, including a group of setae at the posterolateral corner (figure 14), whereas
P
.
(
H
.)
cammooensis
has few setae, generally confined to the posterior part of the sternite (figure 12).
