Paralamyctes (Haasiella) ginini n. sp.

(figures 13–16)

Etymology. From Mt Ginini, one of the occurrences of this species.

Diagnosis. P. ( Haasiella ) distinguished from P. (H.) 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.

Holotype. ANIC-03-35, female (figures 13, 14), South Ramshead , Kosciusko NP, NSW [36°31∞S, 148°15∞E], K. Green, 2 February 1983. Length of head 0.73 mm; length of body 7.5 mm.

Paratypes. ANIC-03-36, female, ANIC-03-37, male, type locality, same collection as holotype; ANIC-03-38, female, type locality, K. Green, November 1981; ANIC-03-39, male, type locality, K. Green, January 1982; ANIC-03-40, female, type locality, K. Green, June 1986; ANIC-03-41, male (figure 15), Mt Ginini , ACT, 35°32∞S, 148°46∞E, 1660 m, J. F. Lawrence and T. A. Weir, 16 October 1979 ; ANIC-03-42, juvenile, 1 km S Mt Ginini , 35°33∞S, 148°46∞ E, J. F. Lawrence, 11 November 1986 ; ANIC-03-43, male, Mt Gingera summit, ACT, 35°34∞S, 148°47∞ E, E. Britton, Misco, 18 July 1967 .

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).
