Dentocypria Savatenalinton, 2017

Type species: Dentocypria mesquitai Savatenalinton, 2017 .

Diagnosis: As in Savatenalinton (2017).

Other species: Species described by Savatenalinton (2017), D. crenulata ( Sars, 1903) comb. nov., D. dumonti Martens, 1982 comb. nov.

Distribution: AT, NT, PA and OL.

Remarks: New combinations are established here for D. crenulata comb. nov. and D. dumonti comb. nov., reallocating these species from Physocypria to Dentocypria , because both taxa have tubercles on the RV margin, a very elongated terminal segment of the Md palp, absence of d1-seta on T 2 basal segment, and a long sp-seta on the CR. All those traits do not fit with the description of Physocypria bullata Vávra, 1897 (see Karanovic 2011), the type species of the genus. In addition, D. dumonti comb. nov. has a subtriangular protrusion on the right prehensile palp of the male, a character unique to Dentocypria . Moreover, the morphology of the hemipenis lobes is closer to Dentocypria than to Physocyria (see below). The transfer of these two species from Physocypria s.l. to the genus Dentocypria has zoogeographical implications. The genus Dentocypria was considered endemic to Thailand ( Savatenalinton 2017), but with the new combinations this genus is now present in other parts of Asia and in Africa; Dentocypria crenulata was originally described from Sumatra ( Indonesia), and D. dumonti was described from Somalia (Africa).

Other species assigned to Physocypria may also belong to Dentocypria , but descriptions are often incomplete and generic position cannot be ascertained. The length of the Md palp terminal segment is unknown in P. furfuracea ( Brady, 1886) , P. larensis Hartmann, 1964 and P. minuta Victor and Michael, 1975 , but they do not have d1-seta on T 2 (a distinguishing character for Physocypria ), and the sp-seta of the CR is long. Their distribution (OL and PA) is also congruent with Dentocypria distribution; however, more information is needed to confirm their generic position. Museum material of these species should be checked paying special attention to hemipenis and prehensile palp morphology.
