Urolophidae (stingarees)

Urolophus paucimaculatus (sparsely spotted sting-

aree) ( fig. 65)

Four specimens of this southern Australian endemic were included in the analysis. The analysis yielded a single tight cluster; the range in pairwise differences among these specimens was 1–5, with an average of pairwise differences of three bases.

Urolophus cruciatus (crossback stingaree) ( fig. 65)

The analysis included three specimens identified as this distinctively colored southeastern Australian endemic species. The range of pairwise differences among these specimens was 1–2, with an average of 1.3. These specimens grouped most closely with those of U. paucimaculatus ; the average of the pairwise differences between these two species was 76.5.

Urolophus westraliensis (brown stingaree) ( fig. 65)

A single specimen of this Australian endemic was included. It is deposited in the Australian National Fish Collection (GN4637 5 ANFC H 4649-23).

Urolophus expansus (wide stingaree) ( fig. 65)

The single specimen of this southwestern Australian endemic species included in the analysis is deposited in the Australian National Fish Collection (GN4656 5 ANFC H 6414-12).

Urolophus viridis (greenback stingaree) ( fig. 65)

A single specimen of this species, a southeastern Australian endemic, was included in the analysis. This specimen is deposited in the Australian National Fish Collection (GN4661 5 ANFC H 2444-04). This species clustered most closely with the specimen of U. expansus , but the sequences of these specimens differed by 44 bases.

Urolophus kapalensis (Kapala stingaree) ( fig. 65)

A single specimen of this relatively newly described Australian endemic (see Yearsley and Last, 2006) was also included. It was taken from a specimen (GN4658 5 H6153- 02) listed among ‘‘other material examined’’ in the original description of this species.

Urolophus lobatus (lobed stingaree) ( fig. 65)

The analysis included one specimen of this Australian endemic, which is in the Australian National Fish Collection (GN4659 5 ANFC H 6346-15).

Urolophus flavomosaicus (patchwork stingaree)

( fig. 65)

Two specimens of this Australian endemic, both in the Australian National Fish Collection (GN4636 5 ANFC H 1036-6 and GN4657 5 ANFC H 1036-37) were included. These specimens were identical in sequence.

Urolophus bucculentus (sandyback stingaree) ( fig. 65)

The analysis included a single specimen of this southeastern Australian endemic. This specimen is deposited in the Australian National Fish Collection (GN4655 5 ANFC H 1269-01). It clustered most closely with U. flavomosaicus . Although these two species were considered to bear a strong morphological resemblance to one another and to be sympatric in Southern Queensland by Last and Stevens (1994), the distinction between these two species both morphologically and geographically is made clear by Last and Stevens (2009). The average of the pairwise differences between the two species was 15.

Trygonoptera imitata (eastern shovelnose stinga-

ree) ( fig. 65)

The four specimens of this newly described southeastern Australian endemic species (see Yearsley et al., 2008) included in the analysis were collected from New South Wales. The range in pairwise differences among these specimens was 1–3, with an average of 1.7. The analysis yielded a single tight cluster comprised of these specimens.

Trygonoptera testacea (common stingaree) ( fig. 65)

A single specimen of this eastern Australian endemic species was included in the analysis. This specimen grouped most closely with the cluster of T. imitata specimens. The average of the pairwise differences between this specimen and those of T. imitata was 141.

Trygonoptera personata (masked stingaree) ( fig. 65)

The analysis included one specimen of this western Australian endemic; this specimen is in the Australian National Fish Collection (GN4635 5 ANFC H 6347-20). This species clustered along with but outside two of its three congeners included in the analysis. The average of the pairwise differences between this species and T. imitata was 131.5, and between T. testacea was 162.

Trygonoptera ovalis (striped stingaree) ( fig. 65)

A single specimen of this western Australian endemic was included in the analysis. This specimen is in the Australian National Fish Collection (GN4634 5 ANFC H 6347- 13). It grouped most closely with but outside its three congeners included in the analysis. The average of the pairwise differences between this species and T. imitata was 155, T. testacea 170, and T. personata 134.
