Species description
Male. Length of forewings 4.9 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. The colouration of the body and wings was observed in specimens preserved in alcohol.
Diameter of eye, in dorsal view, 2.3 times the length of the interocular distance. Anterolateral process of sternum V 1.5 times the length of the sternum.
Genitalia. Segment IX with anterolateral margin rounded ( Figure 4A View Figure 4 ). Tergum X, in dorsal view, deeply divided mesally, internal margin of each hemitergite concave with apex slightly curved to the midline bearing a small fold preapically ( Figure 4B View Figure 4 ); in lateral view with ventral margin almost straight, apex pointed ( Figure 4A View Figure 4 ). Inferior appendages two-segmented, setose; basal portion long (2.5 times the length of the apical segment), narrow basally, broad at apex ( Figure 4A,C View Figure 4 ). Phallus long, tubular; basal portion broad, forming an angle of about 90 ◦ with the distal part ( Figure 4D,E View Figure 4 ); distal portion with apex produced dorsally, bifid in dorsal view ( Figure 4D View Figure 4 ); ventroapical area of phallus membranous when the endophallus is invaginated ( Figure 4E View Figure 4 ). Endophallus membranous, tubular, truncated at apex, without spines or processes; when evaginated the tip can be seen through the dorsal process of the phallus as an oval membranous structure, because of the transversal wrinkles that cover its surface. Internal sclerite long and slender, in lateral view slightly curved in the apex ( Figure 4E View Figure 4 ).
Female. Unknown.
Systematic considerations
This species is related to S. (R.) elisae sp. nov. Both species share the bifid dorsoapical area of phallus. The S. (R.) valeni is distinguished from other species by the tip of
phallus. The bifid apex and the membranous tubular endophallus truncated at apex are the main characters for the identification of this species.
Etymology
This species is dedicated to Valentino, son of one of the authors (JVS). The name valeni is derived from his nickname, “Valen”.
