Smicridea (Rhyacophylax) bifida Rueda Martín and Sganga , sp. nov.
( Figure 1A–E View Figure 1 )
Material examined
Holotype male. Argentina: Salta, El Rey National Park, A ◦ La Sala , 2 March 1999, F. Romero col. ( IML).
Species description
Male. Length of forewings 5.1 mm. Colouration of head and thorax light reddish brown, setal warts and abdomen stramineous. Forewing yellowish, with an oval pale macula parallel to the costal margin (pterostigma), and light brown stripes over transversal veins paler than that of S. peruana ( Figure 5F View Figure 5 ). The colouration of the body and wings was observed in specimens preserved in alcohol.
Diameter of eye, in dorsal view, almost half of the interocular distance. Anterolateral process of sternum V as long as the sternum.
Genitalia. Segment IX with anterolateral margin sinuous ( Figure 1A View Figure 1 ). Tergum X, in dorsal view, deeply divided mesally, internal margin of each hemitergite straight with apex slightly curved to midline ( Figure 1B View Figure 1 ); in lateral view with ventral margin almost straight and apex slightly upturned. Inferior appendages two-segmented, setose; basal segment narrow for a short distance proximally, from where it widens to the apex; apical segment narrow, short, rounded at tip (basal segment three times length of apical segment) ( Figure 1A–C View Figure 1 ). Phallus long, tubular; basal portion broad, forming an angle of about 90 ◦ with the distal part; with dorsolateral retrorse paired processes ( Figure 1D View Figure 1 ); in lateral view distal part with dorsolateral process directed dorsoanteriorly; endophallus dorsoventrally divergent ( Figure 1E View Figure 1 ). Internal sclerite long and slender; in lateral view slightly sinuous and dorsoventrally divergent at the apex ( Figure 1E View Figure 1 ).
Female. Unknown.
Systematic considerations
The male genitalia of this new species is different from the other species described in the genus. The divergent endophallus and internal sclerite are the main diagnostic characters of this species, and are unique in the genus.
Etymology
The name of this species refers to the bifid apex of the phallus.
