Nelidina bifida View in CoL sp. nov.

( Figs 1–9 View FIGURES 1–9 , 28, 29 View FIGURES 28–33 )

Diagnosis. Pygofer ( Fig. 3 View FIGURES 1–9 ) with dorsoapical lobe expanded, fan-like. Style, in lateral view ( Fig. 6 View FIGURES 1–9 ), approximately rectilinear, apex rounded. Aedeagus ( Figs 8, 9 View FIGURES 1–9 ) with shaft arched; with pair of long lateroapical processes, anteroventrally directed, each process with median spine at inner margin.

.

External morphology. Male holotype: length 6.5 mm, male paratypes: length 6.3–7.1 mm (n = 52). External characteristics as in generic description.

Male terminalia. Pygofer, in lateral view ( Fig. 3 View FIGURES 1–9 ), subrectangular; length approximately twice height; dorsal margin rectilinear along basal two-thirds and concave on apical third; ventral margin slightly sinuous; with setae on apical half; apex bilobed, dorsoapical lobe fan-like, large, expanded dorsoventrally and with caudal margin rounded and setose, ventroapical lobe small and rounded. Subgenital plate, in lateral view ( Fig. 4 View FIGURES 1–9 ), with apical half slightly curved dorsally; in ventral view ( Fig. 5 View FIGURES 1–9 ), each plate about 3.2 times longer than maximum width; ventral margin with 6–8 macrosetae distributed on apical half; apex rounded. Style, in lateral view ( Fig. 6 View FIGURES 1–9 ), narrowing gradually towards apex; in dorsal view ( Fig. 7 View FIGURES 1–9 ), with margins approximately parallel; apex rounded. Connective ( Fig. 7 View FIGURES 1–9 ) about two-thirds length of style. Aedeagus ( Figs 8, 9 View FIGURES 1–9 ) with shaft arched, directed posterodorsally at basal half and dorsoanteriorly at apical half; with pair of lateroapical processes approximately two-thirds length of shaft, anteroventrally directed and outwardly arched, each process with median spine at inner margin and with apex attenuate; apex of shaft also with small unciform dorsoapical process strongly curved anteroventrally, and small spiniform ventroapical process; preatrium long, about half length of shaft.

Female unknown.

Etymology. The specific epithet, bifida , comes from the Latin “bifidus” and means bifid. It refers to the pygofer apex ( Fig. 3 View FIGURES 1–9 ).

Material examined. Holotype male: “ Peru, San Martin, Cons. Mun.\ Zona Barreal 23 km S. Picota \ 07°04.88’S 76°18.89’W, malaise, 06–15.iii.2005,\ M.E.Irwin & J.D.Vasquez ” ( MUSM) GoogleMaps . Paratypes: 1m: same data as the holotype ( MUSM) GoogleMaps ; 51m: “ 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”, 9m ( DZRJ), 9m ( INHS), 9m ( MNRJ), 24m ( MUSM) GoogleMaps .

Remarks. Nelidina bifida sp. nov. is similar to N. defila in the shape of the styles ( Figs 6, 7 View FIGURES 1–9 ) and the length and orientation of the processes of the aedeagus ( Fig. 9 View FIGURES 1–9 ). However, the new species can be easily distinguished from other species of the genus by the shape of the dorsoapical lobe of the pygofer ( Fig. 3 View FIGURES 1–9 ) and the presence of a median spine on the paired distal processes of the aedeagus ( Fig. 9 View FIGURES 1–9 ).
