Genus Ornithoica Rondani, 1878

NOTES. Genus Ornithoica includes 24 species distributed in tropical, subtropical and temperate zones in Asia and Africa (Maa, 1969; McClure et al., 1973, with changes and adding). List of host-species of the genus includes 285 genera of birds from 59 families and

17 orders (Maa, 1969). Seven species of the genus are recorder in the Palearctic Region: O.

bistativa Maa, 1966, O. exilis (Walker, 1861) , O. momiyami Kishida, 1932 , O. podicipis von

Röder, 1892, O. stipituri (Schiner, 1868) , O. turdi (Olivier in Latreille, 1811) and O. unicolor

Speiser, 1900 (Soós & Hůrka, 1986; Mogi, 2014). These species are distributed mostly in tropical zones of Old World and, except O. turdi , occur only along the southern edges of the

Palearctic. Two species were recorded on Russian Far East (Farafonova, 2001). Now O. exilis found on Primorskii krai and added to the fauna of Russia. A key to species of the genus known from Russian Far East is given below.

Key to species of the genus Ornithoica from the Russian Far East (modified after Farafonova, 2001)

1. Anal cell of wing twice long as wide. Scutellum with 4‒6 long bristles …...........……….. 2

– Anal cell of wing in three times as long as wide. Scutellum with 8‒10 long bristles. Anchorlike spines near abdominal apex in female scattered and all markedly smaller than those near abdominal base, no multispinose warts. Wing 3.9‒4.4 mm long. [Oriental Region, Japan (Hokkaido, Honshu, Ryukyu Islands), Korean Peninsula, Kazakhstan, Russia (Primorskii krai)] ...…………………………………….………….…... O. unicolor Speiser

2. Body size larger ( Fig. 1 ). Wing 2.8‒3.5 mm long ( Fig. 2 ). Minor scutellar bristles not less than 2/3 as long as major. Para-anal tuft of female is composed of 3‒12 (usually 5‒8) setae which are entirely or mostly uniform in length and robustness, and not shorter than longest bristles on tergite 6. Anchor-like spines near abdominal apex as large as or larger than those near abdominal base ......................................................................... O. exilis (Walker)

– Body size smaller and paler than in exilis . Wing 2.4-2.8 mm long. Minor scutellar bristles distinctly finer and either much paler than or less than 1/2 as long as major ones. Para-anal tuft of female with a few setae, uneven in length and robustness, almost always markedly shorter and finer than longest bristles on tergite 6. [New Guinea, Solomon Is., Australia, Japan, Russia (Primorskii krai)] ................... O. stipituri (Schiner)
