Phascogale t. tapoatafa P. tapoatafa Taxonomic revision of Phascogale tapoatafa (Meyer, 1793) (Dasyuridae; Marsupialia), including descriptions of two new subspecies and confirmation of P. pirata Thomas, 1904 as a ‘ Top End’ endemic Have, Ten Zootaxa 2015 4055 1 1 73 4FVN8 Meyer, 1793 Meyer 1793 [151,708,1804,1831] Mammalia Dasyuridae Phascogale Animalia Dasyuromorphia 22 23 Chordata subSpecies tapoatafa tapoatafa    Holotype:As explained by Mahoney & Ride (1988: 25), “the holotypeis the specimen described and figured under the name Tapoa Tafa by Anon.

Although Troughton (e.g. 1967: 31) notes that “the specimen figured was preserved in the Museum of the Royal College of Surgeons”, neither Thomas (1888)nor Mahoney & Ride were able to locate an appropriate candidate, either in this collection or in the Natural History Museum, London. However, the original plate in White (1790)is unambiguously diagnostic (provided locality data are also taken into account) and neotypedesignation is unwarranted.   TABLE 4a.Summary external measures of male  Phascogale tapoatafagroup specimens used in this study (HV headvent, TV tail-vent, Wgt weight).

An adult male specimen from Coraki in northern New South Wales ( CM20990) is illustrated in Fig. 4. Regional variation is noted after the main account. External measurements taken from museum specimen records are summarised in Table 4. Adults in a Victorian population attained body weights of 311gfor males and 212gfor females ( Soderquist 1995c). The dorsal fur is relatively dense and lush, the contour hairs measuring 12–13 mmin the centre of the back. The overall colour of the back and flanks is grey with a silvery frosting, this effect imparted by narrow white tipping on grey-based contour hairs. Abundant black-tipped guard hairs are distributed evenly over the body and project as much as 9 mmthrough the fur. The mid-dorsal zone is distinctly darker than the flanks owing to a more intense basal pigmentation. Ventral fur colouration varies from grey with an extensive cream wash to predominantly cream (e.g., CM3740). In most specimens, the central strip at least consists of pure cream fur, merging laterally into grey-based fur with a progressively shorter cream tipping. In all specimens, the pale ventral colouration extends anteriorly to the chin, posteriorly to surround the cloaca, and laterally to clothe the inner surface of the fore- and hind-limbs. The scrotum is heavily pigmented and densely clothed in cream fur. A pigmented gular gland is evident on some adult specimens of both sexes but the location of this gland is not marked by any obvious external discolouration of the fur. In some specimens the fur in this region has a slight russet tinge basally. The ventral fur in juveniles tends to be duskier, with a diffuse pale cream wash.   TABLE 5.

Additional facial patterning includes a well-developed, dark russet mid-rostral stripe, a broad and indistinct, dark grey loreal stripe and small, black postorbital spot, distinct off-white infra- and supra-orbital crescents, and a variably expressed cream-tipped preauricular tuft. Preauricular patches are indistinct in around 30 % of specimens and seem to be less conspicuous in juveniles than in adults. In most specimens, the cream fur of the chin and throat extends around the corner of the mouth and merges into a supralabial bar, while the cheek patch is cream peppered with black. The rostral vibrissal pads are densely clothed in short grey fur and the basal papillae are unpigmented and not visible. All facial vibrissae are thick and black, sometimes with gingery tipping. The pinnae are moderately elongate and broad, weakly to moderately pigmented and sparsely furred. The anterior border of each pinna supports a narrow band of short black hairs.   FIGURE 16. Crania and dentaries of  P. tapoatafa tapoatafa. a) CM24425, an adult male from Coraki, New South Wales, and b) CM1316, a subadult male from Wallaby Creek, near Urbanville, New South Wales. Each series consists of (left to right) dorsal view of cranium, ventral view of cranium, and lateral view of right dentary. The basal portion of the tail is thickly furred above and on the sides, and supports numerous projecting guard hairs, continuing the colour and texture of the rump ( Figs 4and 6). The tail narrows rapidly to form a distinct ‘stem’, which is clothed above and below by long, adpressed hairs. Dorsally and around the sides of the tail, these hairs are white with short black tips, while those on the ventral surface are black with short cream tips grading to dark russet at the base of the brush. The tail ‘brush’ is lush and measures up to 165 mm; it consists of jet black hairs except for a short section of dark russet hairs ventrally, at the base of the brush. The basal portion of the tail, from cloaca to base of brush, measures to 90 mm. The upper surface of the pes supports a mixture of white, dark grey and russet hairs, giving it an overall grizzled appearance. This merges into white fur on the sides of the foot and around the heel. The digits are densely clothed in white hairs. The plantar surface of the pes is granular and supports a total of five conspicuously striated pads. The inner metatarsal and first interdigital pads are fused, usually with no obvious line of demarcation; their combined length is 13.1 mm. The outer metatarsal pad is moderately long; on AM932 it measures 7.4 mmand is separated by a gap of 3.9 mmfrom the fourth interdigital pad. The second to fourth interdigital pads are elongate and of subequal length. Both feet on one specimen ( CM1316) show a clear line of demarcation between the conjoined inner metatarsal and first interdigital pads. Females in all populations usually have eight teats in the pouch (e.g. Cuttle 1982; Soderquist 1993a); occasional individuals have seven teats.   FIGURE 17. Graphical representation of geographic variation within  P. t. tapoatafain selected craniodental dimensions (SL; M1-4; FMW). Values for individual specimens are plotted in geographic sequence (Geo Seq) from west to east for South Australia and Victoria, and then from south to north for New South Wales and southeast Queensland. Population codes: 2: South Australia; 3: Victoria; 4: New South Wales and southeast Queensland. Plotted variables are a) Skull Length; b) M1-4; c) Foramen Magnum Width. Left hand series are females; right hand series are males. Cranial and mandibular anatomy of a fully adult male ( CM24425) and subadult male ( CM1316) are illustrated in Figure 16. Cranio-mandibular and dental measurements for each sex are provided in Table 5. The New South Wales to southeast Queensland populations of  P. t. tapoatafashow clear male-biased sexual dimorphism in cranio-dental measurements ( Table 6& Fig. 9). For all dimensions bar one ( FMW), mean values are higher in males than females and for nine dimensions the contrast is statistically significant. This latter subset includes measures of overall cranial size ( SL, ZW, PALW, PRW) and of the lower canine ( C1 L; C1 W), as well as measures that are sensitive to canine enlargement ( C1- M4 L, ARW). The combined South Australian and Victorian sample shows a less pronounced male-biased dimorphism in which statistical significance is attained only for measures of the lower canine. In this population, the contrast in PRW also approaches significance. These observations on the Victorian population are consistent with Soderquist’s (1995c) finding that the marked sexual dimorphism in body weight among Victorian  P. tapoatafais due primarily to somatic energy stores that are laid down in preparation for the short breeding season when foraging effort is curtailed. In the Victorian population studied by Soderquist the ratio of average adult male to female body weights is 1.62 (Soderquist unpublished data, reported by Rhind & Bradley 2002).  Geographic variation.Possible clinal variation within  P. t. tapoatafais observed in various cranial and dental dimensions but with somewhat different expression in each sex. Among males there is a very slight and gradual decrease in cranial length ( Fig. 17a) from South Australia to Queensland, coupled with a more pronounced shortening of the upper molar row that also shows a more abrupt break between southern and northeastern populations ( Fig. 17b). Females show a more pronounced decrease in both cranial and dental dimensions ( Figs 17d–e). Both sexes show an abrupt and significant contrast between southern and northeastern populations in the breadth of the foramen magnum ( Fig 17c,f); this variable is little affected by overall growth of the cranium. The different pattern of geographic variation between the sexes of  P. t. tapoatafais largely a product of the variable expression of sexual dimorphism between the southern and southeastern Australian populations. Essentially, males of  P. t. tapoatafavary only slightly in cranial size throughout their range, while the more pronounced clinal variation in female cranial size, from large in the south to smaller in the north, creates a widening contrast between the two sexes. Overlaid on this pattern is a more pronounced geographic variation in molar size, with southern animals of both sexes having larger teeth on average than those from New South Wales and Queensland. On present evidence, this variation appears to be manifested in different ways between the sexes—step-like in males vsclinal in females—but larger samples from critical areas are needed to be certain of this.   Distribution and conservation status.The historical distribution of  P. t tapoatafacorresponded to the more or less continuous tract of forested country that extended from the southeastern corner of South Australia, extending across most of Victoria (probably excluding only the northwestern mallee region and country above the treeline) and then running north along the coastal strip and mountainous hinterland of New South Wales and Queensland, north at least to Mackay ( Fig. 18). A recently collected sub-fossil specimen from Ukerbarley station, 7 kmNW of Coonabarabran ( Fig. 18& Table 9), indicates that populations of this taxon once occurred on the western slopes of the Great Dividing Range in New South Wales. Whether any of these survived into historical times is not known. At the western end of its range, a population of  P. t. tapoatafawas recorded historically in the Mt Lofty Ranges of South Australia ( Fig. 18). Although Wood Jones (1923)understood the range of this species (as  P. penicillata) to extend to the Murray River, sub-fossil collections from several archaeological sites in this area have failed to confirm its former presence ( Wakefield 1964). Morphologically, the few available specimens from the Mt Lofty population appear to be indistinguishable from Victorian specimens. However, in the absence of genetic data, it is not possible to decide whether the Mt Lofty population was genuinely isolated or not. Caution in this regard is further indicated by a subfossil record of  P. tapoatafafrom a cave deposit of mid-Holocene age on Kangaroo Island ( Fig. 18& Table 9), indicating a wider distributional and habitat range than might be inferred from the few historical records alone. As reported in a later section, populations of  Phascogale tapoatafaare also present in northern Queensland. These resemble the nominate race in most morphological features but show a moderate level of genetic differentiation (albeit based on a single individual from the northern population). Today these populations appear to be separated from those in the south by a gap of more than 400 kmof significantly drier habitat. However, a subfossil record of  P. tapoatafafrom Christmas Creek, inland of Townsville ( Table 9) signals the possibility of recent continuity between these populations. The northern Queensland population is herein left unallocated at subspecific level.   FIGURE 18. Map of eastern Australia, showing the contemporary (dark grey) and historic (light grey) distribution of  P. tapoatafa tapoatafa, based on museum specimens and reliable sightings. Star symbols are sub-fossil records judged to be of late Holocene age. Square symbols represent the location of two sight records that might pertain to either P. pi r at aor  P. tapoatafa. Although Victoria, New South Wales and Queensland still host populations of  P. t. tapoatafa, its geographic range is now extremely fragmented and many regional populations are in decline. Indeed, the only region in which the taxon might be said to be secure is southeastern Queensland.  Phascogale tapoatafais probably extinct in South Australia, with the last vouchered record dating to 1969. Wood Jones (1923: 101–102) remarked on the former abundance of the species in South Australia and noted that it was known to “the South Australian Murray River natives’ as “ pundi”. He also speculated on the possible existence of populations of this taxon “over a wide area in the Centre”. It is possible that these reports referred instead to  P. calura, which Wood Jones tentatively included in the South Australian fauna on the basis of an early record from ‘Adelaide’ but otherwise knew little about. In fact, Spencer and Gillen had obtained several specimens of P. c a l u r afrom Central Australia prior to 1901 ( Baynes & Johnson 1996), although no further specimens were obtained from this area.    Phascogale t. tapoatafahas been the focus of several field studies in Victoria ( Cuttle 1978, 1982; Soderquist 1993a, 1993b, 1994a, 1994b, 1995a; Soderquist & Ealey 1994; Soderquist & Lill 1995) but little is known of the species’ ecology in New South Wales or Queensland. The difference between these populations in the degree of sexual dimorphism suggests caution in assuming a uniformity of all aspects of ecology among populations of this widespread subspecies. Dixon & Huxley (1989)reported extracts concerning Victorian  P. tapoatafafrom the natural history notes of Donald F. Thomson, drawn primarily from sources on the Bellarine Peninsula where the species was so common in the 1940s–1960s that it invaded local residences and was regarded as a nuisance. There are no modern records of the species in this area.
