Malarinia Haas, 1961: 19 View in CoL .

Tope species: Malarinia hova Haas, 1961 View in CoL , by original designation.

Included species: Malarinia hova Haas, 1961 ( Fig. 10E View Figure 10 ) and Malarinia calcoperculata Emberton, 1994 ( Fig. 10F View Figure 10 , see also Emberton & Pearce, 1999: 364, fig. 22).

Remarks: We examined photographs of the type species of Malarinia ( Madagascar, ~ 30 miles south of Moramanga, Chutes de la Mort, leg. E.S. Ross, 10 November 1959, FMNH 106701). Te strong sculpture on the last half whorl suggests that each rib represents a microtunnel, as in the genera Boucardicus and Anosocolus. So far, this genus has been placed in the family Diplommatinidae , which has no other known members in Madagascar or in the entire African continent ( Egorov 2013). Tus, its position in the Boucardicinae is more likely, and it is here moved to Boucardicinae .

Boucardicus menoi K. C. Emberton, Slapcinsky, C. A. Campbell, Rakotondrazafy, Andriamiarison & J. D. Emberton, 2010 View in CoL and Boucardicus avo K. C. Emberton, Slapcinsky, C. A. Campbell, Rakotondrazafy, Andriamiarison & J. D. Emberton, 2010 View in CoL are very similar to two known Malarinia species in shell shape and sculpture ( Emberton et al. 2010). It is possible that they are wrongly assigned to Boucardicus View in CoL and should instead belong to Malarinia View in CoL . However, it might also mean that there is no clear morphological distinction between Malarinia View in CoL and Boucardicus View in CoL . Given that Malarinia View in CoL is the older name, it has priority over Boucardicus View in CoL , and the ~200 species of the later genus should be transferred to Malarinia View in CoL . However, we do not formally synonymize Boucardicus View in CoL with Malarinia View in CoL here. Instead, a systematic revision of the extremely variable Boucardicus View in CoL should propose a reasonable subdivision of that genus.
