(New name for Lodiana Nielson , nec Lodiana Ragonot 1888 ).

Type species. Lodiana alata Nielson 1982: 86

Description. Medium to large, robust species. Length male 6.40-9.30 mm., female 9.10-9.70 mm. Similar to Calodia in general habitus; aedeagus long, narrow, tubular with single short to long, subapical to apical, setose and/or spinaceous process, sometimes with small teeth or small setae near or adjacent to subapical process; pygofer without prominent caudodorsal process, always with small lobe apically, often with caudoventral process, glabrous or with sparse to numerous setae; style variable, very long to short, often robust, rarely with secondary process; subgenital plate glabrous to setose. The long, narrow, tubular aedeagus with a single long, spinose and/or setose process will distinguish the genus from others of the tribe. The genus is the largest group in the tribe and widespread throughout the Oriental and southern Palearctic regions. Seventy nine valid species comprise this genus, including 10 new species and 12 new combinations. Two species are provisionally assigned to this genus and designated incertae sedis because papers on original descriptions and type specimens were not available. Four species are reinstated and 1 new synonym, Olidiana yangi McKamey , is cited in the check list and catalogue.

Interspecific variation. Six species in a proposed Olidiana brevis (Walker) species complex share 2 broad, yellow to orange, transverse bands against a dark brown to black background on the forewings, except O. praetexta (Distant) which is atypical but has very similar aedeagal features and 2 very narrow transverse translucent ivory bands. Five species are unidentifiable without recourse to features of the male genitalia. The complex is widely distributed in the following countries: O. brevis (Walker) [ Bangladesh, China, Laos, Myanmar, Thailand, Vietnam]; O. brevisina (Zhang) [ China]; O. egregia (Schumacher) [ Taiwan]; O. flavofascia (Zhang) [ China]; O. praetexta (Distant) [ Myanmar] and O. uenoi (Hayashi) [ Japan]. Diagnostic features of the male genitalia are shown in Figures 1-12 and in Table 2. A separate key to species is also presented. Photographs of the lectotype male and syntype female of Jassus egregius Schumacher are shown in Plate 3 , G and H, respectively.
