Taxonomy of Strandesia View in CoL

Bradleycypris obliqua ( Brady, 1868) was placed in Strandesia View in CoL by Karanovic (2005), but we reject this decision, as characteristics of this species do not conform to those of Strandesia View in CoL s.s. As was mentioned above, B. obliqua , (the type species of this monospecific genus) has a strongly oblique carapace in frontal view and no inner list on the LV. Martens et al. (2008) accounted for 134 species in Strandesia View in CoL s.l. worldwide. Here, we retain a subset of these species in Strandesia View in CoL s.s. ( Table 5). Eleven species of Strandesia View in CoL are allocated to Bradleystrandesia View in CoL ( Table 6) because of the presence of the Triebel’s loop in the dorsal branch. The following comments can be added.

Bradleystrandesia crassa ( Klie, 1939)

Bradleystrandesia dani ( George & Martens, 1993)

Bradleystrandesia decorata (Sars, 1903)

Bradleystrandesia lineata ( Victor & Fernando, 1981) Syn. : Strandesia amati ( Martens, 1984)

Bradleystrandesia parva ( Hartmann, 1964)

Bradleystrandesia tolimensis ( Roessler, 1990)

Bradleystrandesia trichurensis ( Victor et al., 1980)

Bradleystrandesia trispinosa ( Pinto & Purper, 1965) Syn. : Strandesia trispinosa galantis ( Broodbakker, 1983)

Bradleystrandesia tuberculata ( Hartmann, 1964)

Bradleystrandesia umbonata ( Victor & Fernando, 1981)

Bradleystrandesia weberi ( Moniez, 1892)

Strandesia amati ( Martens, 1984) strongly resembles Strandesia lineata Victor & Fernando, 1981 View in CoL , in valve ornamentation and in shape of the carapace. These species were considered by Martens (1984) as different taxa, owing to a number of different morphological features, e.g. the relative length of A2-claws, the length of the A2-aesthetasc, the shape of the Triebel’s loop and the number of rays on T1-respiratory plate. However, a comparison of the original descriptions of S. amati and S. lineata View in CoL , as well as new material from Thailand, reveals that these two taxa should be considered synonyms. Although there is some morphological variability in the chaetotaxy mentioned above, as well as in the setae on the T2-terminal segment, this is most likely owing to the fact that S. lineata View in CoL was described from last juvenile stage specimens ( Victor & Fernando 1981) in which limbs and setae are not yet completely developed. Strandesia amati is thus sunk in to the synonymy of S. lineata View in CoL and the latter species is transferred to Bradleystrandesia View in CoL .

Strandesia bicornuta was described from India ( Hartmann 1964). The original description and illustrations were incomplete and even questionable in some features, so that the position of this enigmatic species remained uncertain. Martens & George (1992) redescribed the species on material from Kerala ( India). These authors mentioned that the species has more affinities with the South African Cypricercus View in CoL lineage than with Strandesia View in CoL , relying on the presence of anterior and posterior spines and the absence of a dorsal protuberance. However, after rechecking materials in the R.B.I.N.Sc. which were collected from Kerala State, India by Martens & George (1992) (specimes O.C. 1661–1670), it can be confirmed that this species belongs to Strandesia View in CoL s.s., as it has the typical characters of Strandesia View in CoL described above.

Strandesia trispinosa , previously in Cyprinotus View in CoL , was described from southern Brazil by Pinto & Purper (1965). This species was divided into 2 subspecies, S. trispinosa trispinosa and S. trispinosa galantis , by Broodbakker (1983). Although the morphology of the soft parts of both forms was identical, Broodbakker (loc. cit) decided to erect this new subspecies because of the geographical distance. However, this view is ruled out since S. trispinosa galantis has recently also been recorded from the Paraná River ( Brazil) ( Higuti et al. 2007). Based on a comparison of the descriptions of these two subspecies and on a reexamination of material of S. trispinosa from Brazil, we conclude that the variation in length of the anterior and posterior spines is insufficient to warrant distinction between subspecies. Hence, S. trispinosa galantis is here considered a synonym of the nominotypical form. In addition, we lodge S. trispinosa in Bradleystrandesia View in CoL , because of the presence of the Triebel’s loop in the dorsal branch of the caudal ramus attachment.

The exact position of most of the other Strandesia View in CoL and Cypricercus View in CoL species remains unclear, mainly because of the incomplete descriptions of these species. In most cases, no account is provided of the appearance of the α-seta on the Md-palp and of the d-seta on the T1, which are significant taxonomic features of this group. These uncertain species are listed in Tables 4 and 7 for Cypricercus View in CoL and Strandesia View in CoL , respectively.
