Stirellus rubrolineatus, Emeljanov, 1962: 238 ; Day & Fletcher, 1994: 1199. Doratulina rubrolineata, Zahniser & Nielson, 2012: 49 .

Length. Male: 4.8–5.1mm.

Color. General color tannish ( Fig. 22 ), pale sordid yellow in older museum specimens. Vertex with transverse band interrupted medially and two dots under the band, orange-red to brownish red ( Fig. 22 A–B). Frontoclypeus with two black markings on each side just below antennal sockets ( Fig. 22 D).

Body. Head narrower than pronotum, anterior margin rounded to face, rounded. Vertex nearly as long as width between eyes ( Fig. 22 A–B). Ocellus next to eye on anterior margin ( Fig. 22 C). Eye relatively large ( Fig. 22 A–B). Apex of anteclypeus widened, extending beyond normal curve of genae ( Fig. 22 D). Pronotum median length slightly longer than median length of crown. Mesonotum and scutellum shorter than pronotum ( Fig. 22 A–B). Forewing macropterous ( Fig. 22 A–C).

Male. Pygofer side without macrosetae, apex as Fig. 23 A ( Fig. 23 A–B). Subgenital plate rounded laterally, macrosetae uniseriate laterally ( Fig. 23 D). Style narrow, apophysis usually thick, thumb-like, laterally curved ( Fig. 23 E–G), sometimes apophysis slightly more slender ( Fig. 23 G, China male). Connective stem shorter than arms ( Fig. 23 H). Aedeagal shaft bent at near base, long, tip slightly curved dorsad, parallel to aedeagal base ( Fig. 23 I– K).

Material examined. Lectotype: Ƌ, here designated, of Arya rubrolineata Distant , India, Calcutta , 23 August 0 7, Mus. Coll., Distant Coll. 1911–383 ( BMNH) . Paralectotypes: 2♀, same data as lectotype, except 5 August 0 7, 16 November 07; 1Ƌ (in poor condition), India, L. Bengal, Barrackpore, N. A., 11 August 0 7, Mus. Coll., Dist. Coll. 1911–383, with Distant’s type determination label and red type disc ( BMNH) . Other material: 2Ƌ, China, Hainan Prov., Bawangling , 27 May 1983, coll. Zhang Yalin.

Distribution. India; China (Guizhou, Hainan, Taiwan).

Remarks. This species was described from an unknown number of specimens (syntypes) from India with the following data: “ Calcutta , Barrackpore ( Annandale , Ind. Mus. & Coll. Dist.)”. Two male and two female syntypes are present in the BMNH of which the most complete male (Calcutta, remounted on a card) is selected as lectotype . The two type series males differ from the Chinese material in having the aedeagal shaft slightly incurved at midlength and the pygofer slightly more elongate and upturned apically in lateral view. Aconura rubrofasciata Matsumura is placed as a junior synonym based on images seen of the type habitus and genitalia ( Fig. 24 ) which match our Chinese material. It was described from a single male specimen (holotype) from Taiwan. This species can be distinguished from other congeners from China by the vertex with a transverse band interrupted medially and two dots under the band, orange-red to brownish red ( Fig. 22 A–B).
