Smicridea (Rhyacophylax) elisae Rueda Martín and Sganga , sp. nov.

( Figure 1F–J View Figure 1 )

Material examined

Holotype male. Argentina: Salta, Chicoana, Rio Chicoana , 29 February 2000 ( IML).

Paratypes. Same data as holotype: two males ( IML) .

Species description

Male. Length of forewings 6.1 mm. Colouration of head and thorax light reddish brown, setal warts, antennae, legs and abdomen stramineous. Forewing yellowish, with an oval pale macula parallel to the costal margin (pterostigma), and brown stripes over transversal veins with a transversal line at the mid-length of anastomosis of R. The colouration of the body and wings was observed in specimens preserved in alcohol.

Diameter of eye, in dorsal view, 2.3 times the interocular distance. Anterolateral process of sternum V about 1.5 times the length of the sternum.

Genitalia. Segment IX with anterolateral margin angulated ( Figure 1F View Figure 1 ). Tergum X, in dorsal view, deeply divided mesally with a V-shaped excision ( Figure 1G View Figure 1 ); in lateral view with ventral margin almost straight and apex slightly upturned, dorsal area membranous ( Figure 1F View Figure 1 ). Inferior appendages two-segmented, setose, basal segment broadened apically (four times the length of the apical portion); apical segment short, rounded at the tip ( Figure 1F–H View Figure 1 ). Phallus long, tubular and curved; basal portion slightly broader; apical area with dorsal bifid process and ventral quadrangular membranous structure with internal folded membrane (endophallus partially exerted), internally with a dorsal sclerotized, pyriform plate (cleft meso-posteriorly) ( Figure 1I,J View Figure 1 ); endophallus long and digitate. Internal sclerite sinuous in lateral view and slightly broadened in dorsal view ( Figure 1I,J View Figure 1 ).

Female. Unknown.

Systematic considerations

The male genitalia of this new species could be related to S. (R.) valeni sp. nov. because of the bifid dorsal process of phallus. The folded membrane in the apex of phallus and the sclerotized plate are the main diagnostic characters of S. (R.) elisae sp. nov.

Etymology

This species is dedicated to Dr Elisa Beatriz Angrisano, researcher in Trichoptera from South America and director of the doctoral thesis of both authors.
