Remarks. Anaspides swaini   is distinguished from other congeners by the combination of the angular posterior margin of the telson, blunt or minutely spinose posterolateral angles of pleonite 6, and the presence of two clasping spines in adult males ( Fig. 30B,C,E View Figure 30 ). Anaspides swaini   ranges widely in southern Tasmania, from the Wellington range in the southeast, southwest to the Snowy and Arthur Ranges, flanking lakes Pedder and Gordon, and north to the vicinity of Lake St Clair ( Fig. 36 View Figure 36 ).

Three subtly different morphological forms of A. swaini   are recognized here. Form 1 ( Figs 29–31 View Figure 29 View Figure 30 View Figure 31 , 32A–U View Figure 32 , 34A–H View Figure 34 ), corresponds to A. swaini   sensu stricto and has short spines along the upper posterior margins of pleonite 6 (and often pleonite 5 in specimens from the vicinity of Weld River, Vale of Rasselas and caves in the vicinity of Mt Field), 1–3 small spines on the pleura of pleonites 4–5, no endopod on pleopod 5 (except in specimens from the Vale of Rasselas, and some specimens from Mt Mueller and Federation Peak), and a usually trifid proximal tooth on the right mandibular incisor process. Form 1 has a southern range, essentially around the periphery of Lake Gordon and Lake Pedder, from Lake Rhona to Mt Field (where it may overlap with A. richardsoni   ) and Mt Mueller to the Snowy Mountains, Federation Peak, the Arthur Ranges and at least as far north as Coronation Peak on the southwestern side of Lake Pedder. Note that the distributional overlap between A. richardsoni   and A. swaini   at Mt Field is largely epigean versus subterranean, respectively, though the two species are occasionally sympatric in surface waters of Mt Field. Specimens labelled as possibly from “?Orford” are juvenile A. swaini   , with antennular modifications as yet incomplete in the male. As argued by O’Brien (1990), the Orford locality is almost certainly erroneous, being well outside of the known range of A. swaini   ( Fig. 36 View Figure 36 ). Moreover, the specimens correspond most closely to specimens from the Vale of Rasselas, having a spinose pleonite 6 and pleura 4–5 (larger juvenile), and an endopod on pleopod 5.

Form 2 ( Figs 32V–Y View Figure 32 , 33K–T View Figure 33 , 34I–U View Figure 34 ) has a northern range largely beyond Lakes Gordon and Pedder. On the surface, Form 2 ranges from the western vicinity of Lake St Clair including the Cuvier Valley and Mt Rufus south to Butlers Gorge and Wentworth Hills and Frenchmans Cap; it continues further south in caves in the Nicholls Range karst (Bill Nielson) and Franklin River karst (Kutikina), where it is apparently isolated from surface forms ( Eberhard et al., 1991). Specimens of Form 3 typically have a few spines on pleonite 6, unarmed pleura 4–5 (occasionally 1 or 2 small spines on pleuron 5), presence of the pleopod 5 endopod in adults (variable in specimens from Frenchmans Cap) and a bifid right proximal mandibular incisor tooth.

Form 3 ( Fig. 33A–J View Figure 33 ), has a southeasterly range, stretching from the western and northern Wellington Range, including the North West Bay River catchment of Mt Wellington, to at least the Huonville area; it may overlap with A. tasmaniae   at Mt Wellington (see Remarks under account of A. tasmaniae   ). Form 3 has similarly minimal pleonal spination as Form 2, but usually lacks the pleopod 5 endopod and usually has a trifid right proximal mandibular incisor tooth as in Form 1. Form 3 also frequently has a less angular posterior margin of the telson than Forms 1 and 2.

The three forms, however, are not strictly discrete morphologically, with some intergrading in parts of their ranges. For instance, at Lake Tahune and Frenchmans Cap, at the southern end of the epigean range of Form 2 (northern), the condition of the pleopod 5 endopod is variable, being present or absent on one or both sides. Similarly, specimens from the Vale of Rasselas in the northern range of Form 1 (southern) share features of Forms 1 and 2 in the pleonal spination of the former and presence of the pleopod 5 endopod of the latter. In addition, the presence of the pleopod 5 endopod in some specimens from Federation Peak in the southern part of the range of Form 1 is anomalous. Morphological and distributional continuity between Form 1 and Form 2 is consistent with the likely persistence of A. swaini   in periglacial lakes formed to the west of Lakes St Clair and King William during the Pleistocene glaciations that dominated most of the Central Plateau and adjacent areas ( Kiernan, 1990). These lakes and associated glaciers fed the Franklin and Gordon Rivers in which A. swaini   is widespread. Forms 1 and 2 both occur to the west of the biogeographic discontinuity known as Tyler’s Line ( Shiel et al., 1989; Mesibov, 1994; Andrew, 2005), and Form 3 to the east.

Overall, A. swaini   from the southwest generally have a more spinose pleon and usually lack the pleopod 5 endopod whereas northern and southeastern specimens are minimally spinose, and generally with (northern) or without (southeastern) the pleopod 5 endopod. Each of these forms might represent separate species or subspecies, but until more detailed population data are available, they are considered to represent a single wide ranging species.

Within the three broad forms of A. swaini   identified here, specimens are rather consistent morphologically. The largest Butlers Gorge specimen (female, 36 mm) is aberrant, however, in having a posteriorly rounded rather than angular telson, and the 34 mm female has an abnormal pleopod 5 exopod that is basally trifurcate. A male from Lake Tahune (29 mm, AM P99165 View Materials ) has the right pleopod 3 endopod developed like the modified pleopod 2 endopod. Two lots of A. swaini   labelled as from “Lake St Clair?” and “Lake St Clair” collected in 1937 and 1941, respectively, are probably from creeks in the vicinity of the lake rather than the lake itself as argued by Nicholls (1947), Williams (1965a) and O’Brien (1990). All specimens from Lake St Clair proper, including juveniles, exhibit the characteristic pleon and telson spination of A. spinulae   .

Like other epigean species of Anaspides   , A. swaini   also occurs in caves ( Fig. 34 View Figure 34 ): Mt Anne (Deep Thought Cave), Mt Field (Junee-Florentine and Risby’s Basin systems), Nicholls Range (Bill Nielson Cave), Franklin River karst (Kutikina) and Mt Ronald Cross karst (Capricorn Cave). These subterranean specimens resemble epigean forms, and at most show more elongate antennular flagella, slightly reduced corneal size ( Fig. 34A View Figure 34 ), and sometimes reduced pigmentation, unlike more strongly cave adapted populations of A. richardsoni   and A. jarmani   , or obligate troglobites such as A. clarkei   and A. eberhardi   , with noticeably reduced corneas and pigmentation. Specimens, from Khazad Dum ( Fig. 34E–H View Figure 34 ) and Risbys Basin caves, presently known only from ♀♀, have a more rounded posterior telson margin, armed pleonite 5–6 terga and usually armed pleura as well; they are strongly pigmented as in epigean specimens. Eberhard et al. (1991) delineated three morphological types of telson in Anaspides   : a “normal” form as exhibited by epigean populations; a “cave” type, in which the telson spines are few in number, stout and widely spaced (as in A. clarkei   and A. eberhardi   ); and an “intermediate” form, recorded from Capricorn Cave ( Fig. 34S–U View Figure 34 ) and Deep Thought ( Fig. 34A–D View Figure 34 ). Re-examination of the “intermediate” form specimens showed the Mt Anne telson to be of the “normal” type, and the Capricorn Cave specimen to be a very early stage juvenile (with normal spination for its stage) in which the telson ornamentation is yet to be fully developed. No specimens have so far been observed with a telson that could be considered as intermediate between the “normal” and “cave type ”, with the possible exception of an aberrant specimen of A. clarkei   with asymmetrically developed spination ( Fig. 8W–Y View Figure 8 ).

Sexual maturity (indicated by development of secondary sexual features) is usually reached by 18–23 mm body length in both sexes, typically 20–21 mm. Unusually, however, at Lake Picton, parts of the Snowy Range including Lake Skinner, Hartz area, Lake Rhona, and two Mt Wellington localities (St Crispins Well, Wishing Well), secondary sexual characteristics are not expressed until very late, at sizes well above that which individuals are otherwise sexually mature (24–33 mm, usually 28 mm body length or above). Additionally, development of secondary characteristics in these immature males seems to be particularly attenuated, with an incomplete complement of antennular clasping spines. Because of their relatively large size, these immature male A. swaini   with as yet incomplete antennular modification could be overlooked as A. richardsoni   , which has only one antennular clasping spine in adult males. The causes of the late onset of sexual maturity are not known.

Distribution. Southern Tasmania from the Weld River, Snowy Mountains region, Mt Field and Mt Wellington (North West Bay River catchment) to the Western Arthurs, throughout the Franklin-Gordon drainages, north to Lake Rhona and Frenchmans Cap, Mt Rufus and the vicinity of Lake St Clair; 300–1440 m asl (epigean), 30–1000 m asl (subterranean).
