description: Nelidina platypenis sp. nov.
(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).
