Redescription

ɗ, BL: 11.9–14.2 mm; HL: 1.8–3.2 mm; HW: 1.3–1.7 mm; FWL: 9.2–10.6 mm. Ψ, BL: 13.4–14.1 mm; HL: 2.0–2.5 mm; HW: 1.3–1.6 mm; FWL: 9.8–10.8 mm.

General color ochraceous, marked with fuscous and brown. Vertex ochraceous, with median, longitudinal, yellowish stripe. Genae mostly ochraceous, areas surrounding ocellus and antenna beneath eye yellowish or yellowish brown. Frons and postclypeus yellowish or yellowish brown, anteclypeus and labrum fuscous. Rostrum with basal segment pale ochraceous, apical segment brown with extreme apex black. Pronotum ochraceous, suffused with blackish brown; median carina yellowish; lateral, ventrally curved areas with broad oblique yellowish band. Mesonotum ochraceous, with median longitudinal yellowish stripe, maculae pale brown. Thorax ventrally dark brown, marked with yellowish or yellowish brown. Legs ochraceous or fuscous, marked with pale brown; coxae blackish brown; femora dark brown or fuscous (hind femora much darker), with numerous pale brown speckles; tibiae pale brown with two broad fuscous rings basally and medially, respectively; tarsi and claws brown (hind tarsi and claws much paler), tips of apical spines on hind tibiae and tarsi black. Abdomen with tergites and sternites dark brown, covered with yellowish brown spots; pygofer and parameres fuscous.

Head ( Figs. 11, 12 , 76–78 ) relatively short, shorter than pronotum and mesonotum combined. Vertex ( Figs. 11, 12 , 76 ) with cephalic process relatively short, converging anteriorly, somewhat upturned; with median carina only conspicuous at apex and base, middle 1/3 faint; lateral carinate margins curved in front of eyes. Frons ( Figs. 11, 12 , 78 ) with lateral carinae reaching to middle of eyes, not to frontoclypeal suture.

Mesonotum ( Figs. 11, 12 , 76 ) tricarinate on disc, with median carina conspicuous, not reaching to extreme tip. Fore wing venation as in Fig. 72 .

Male genitalia with pygofer ( Figs. 79–81 ) short and broad in lateral aspect ( Fig. 80 ), posterior margin straight and angularly excavated at apical 1/4 apex to accommodate anal tube, length ratio of upper margin to lower margin about 1:2. Anal tube ( Figs. 79, 80 ) rectangular, broad and large in lateral view and oval and large in dorsal view, ratio of length to width at middle about 1.3: 1. Anal style ( Figs. 79, 80 ) short, broad. Parameres ( Figs. 80, 81 ) relatively small and narrow in lateral aspect ( Fig. 80 ), apex sharply rounded, protruded backward. Aedeagus ( Figs. 83–85 ) with phallobasal conjunctival processes directed lateroposteriorly; phallobase narrow, long, curved dorsally, apicodorsal, membranous lobe small and short, without spines ( Fig. 85 ), apicoventral, membranous lobe larger and longer, produced toward base, divided into pair of small lobes at apex covered with numerous fine spines ( Fig. 83 ).

Remarks

This species can be distinguished from other known species of Saigona by the aedeagus with phallobase having the apical, ventral, membranous lobe divided into a pair of small lobes covered with numerous fine spines at apex. It is similar to S. capitata ( Distant, 1914) and S. taiwanella Matsumura, 1941 but can be separated from these two species by its distinctly shorter cephalic process (the cephalic process is distinctly longer in the latter two species).

Distribution

Russia (Far Eastern Region), Japan, Korea, northeastern China (Jilin, Heilongjiang).
