TYPE MATERIAL: 1 ♀ , lectotype (in poor condition, covered with mold) ( MZUF : Box 72): Ephydra ciligena R., Am. Mer. [= South America] / holotype , Ephydra ciligena Rondani, P.J. Clausen, 1984 / correct genus now Dimecoenia , P.J. Clausen, 1984 / lectotype [not designated] ♀ , Ephydra ciligena Rondani , by P.J. Clausen / [no identification number ]. CURRENT STATUS: valid species, as Parydra ciligena ( Wirth 1968: 22 ) ; valid species, as Dimecoenia ciligena ( Mathis & Zatwarnicki 1995: 239 ) . REMARKS: Rondani (1868b: 32) described Ephydra ciligena , without specifying the number , the sex or the length of the specimens, from material received from P. Strobel. Rondani (1868b) indicated the type locality as Buenos Aires ( Argentina ) where Strobel taught from 1865–1867, but the specimen itself is labeled “ Am. Mer. ” (= “ America Meridionali ”) [South America]. Philip J. Clausen examined the MZUF type material in 1984, adding the label “ lectotype ” under the single female, without publishing any lectotype designation. We also found just one syntype in this study. In order to promote nomenclature stability, we give credit to P.J. Clausen and here designate as a lectotype for Ephydra ciligena Rondani, 1868 the female labeled as such by him.
