( Figs 19–27 , 32, 33 ) Diagnosis. Pygofer ( Fig. 21 ) with dorsoapical lobe narrow and curved ventrally, horn-shaped. Style, in lateral view ( Fig. 24 ), slightly broadened medially, apical third strongly curved dorsally. Aedeagus ( Figs 26, 27 ) with shaft strongly flattened dorsoventrally; with pair of short and narrow preapical lateral processes and pair of stout medial lateral processes; shaft also with digitiform dorsal preapical process. External morphology. Male holotype : length 7.2 mm , male paratype : length 6.9 mm . External characteristics as in generic description. Male terminalia. Pygofer, in lateral view ( Fig. 21 ), subtriangular, length approximately twice height; dorsal margin slightly convex and declivous posteriorly; ventral margin sinuous at basal half and rectilinear at apical half; setae distributed on apical two-thirds; dorsoapical lobe narrow and curved ventrally, horn-shaped; ventroapical lobe small and rounded. Subgenital plate, in lateral view ( Fig. 22 ), with dorsal margin slightly concave; in ventral view ( Fig. 23 ), each plate about 4.3 times longer than maximum width; ventral margin with 4–6 macrosetae distributed on apical third. Style, in lateral view ( Fig. 24 ), with apophysis slightly broadened medially, apical third curved dorsally, apex slightly bilobed; in dorsal view ( Fig. 25 ), apophysis with external lateral margin convex medially. Connective ( Fig. 25 ) about half length of style. Aedeagus ( Figs 26, 27 ) with shaft strongly flattened dorsoventrally; in caudal view ( Fig. 27 ), broad medially; lateral margins slightly crenulated on apical half; with two pairs of lateral short processes, one pair of narrow preapical processes, ventrally directed, and one pair of stout median processes, posteriorly directed; in lateral view, with digitiform dorsal preapical process, flattened laterally; apex flattened laterally and slightly expanded dorsoventrally; preatrium long, about one-third length of shaft. Female unknown. Etymology. The specific epithet, platypenis , combines the Greek “platy”, which means flat, with the Latin “penis”, referring to the flat shape of the aedeagus ( Fig. 26 ). Material examined. Holotype male : “ Peru , Huanuco , 5 km W.\ Tingo Maria, Pte. Monzón\ 600m , 9°19’32”S 76°1’47”W \ 26 Oct 2002 , R.A.Rakitov\ merc. Vapor light, 02-42.2” ( MUSM ). Paratype : 1m : same data as the holotype ( DZRJ ). Remarks. Nelidina platypenis sp. nov. is similar to N . sportula in the shape of the pygofer apex ( Fig. 21 ). However, the new species can be easily distinguished from other species of the genus by the presence of two pairs of processes on the aedeagus ( Fig. 27 ).
