Genus Pseudopsyra Hebard, 1922

Pseudopsyra Hebard, 1922: 154

Type species: Pseudopsyra mirabilis Hebard, 1922

Diagnosis. Male tenth abdominal tergite produced into a large plate that conceals the epiproct. Male subgenital plate with long styli. Ovipositor narrow; with lateral surface granulated at apical half; with dorsal margin serrated at apical half; with ventral margin crenulated at apical half ( Liu & Kang, 2006).

Comparison with other genera. Pseudopsyra is most similar to Psyrana , Holochlora and Tapiena ( Liu & Kang, 2006; Tan, 2014). A key below distinguishes these relatively similar genera.

1. Stylus of male subgenital plate long, about as long as the half the subgenital plate length.............................................................. 2

- Stylus of male subgenital plate short, distinctly shorter than half the subgenital plate length.......................................................... 3

2. Head and pronotum smooth. Tegmen with distinct Costal vein. ..................................................................................... Pseudopsyra

- Head and pronotum densely punctuated. Tegmen without distinct Costal vein. .................................................................... Tapiena

3. Tegmen with smooth texture, sub-transparent. Female ovipositor with dorsal margin abruptly curved .......................... Holochlora

- Tegmen with coarse texture. Female ovipositor with dorsal margin gradually curved .......................................................... Psyrana

Species richness and distribution. There are currently four described species: two species from southern China ( P. hainani Liu & Kang, 2006 and P. yunnani Liu & Kang, 2006 ) and two species from Peninsular Malaysia ( P. mirabilis Hebard, 1922 and P. bispina Tan & Kamaruddin, 2013 ) ( Fig. 1 ). The most recent key to species is available ( Tan & Kamaruddin, 2013). Below, we describe a new species from Thailand . This represents the first record of this genus from Thailand. It is not surprising given that the current northern and southern most parts of the genus distribution includes Indo-China ( Fig. 1 ). It is therefore highly plausible that more species of undescribed Pseudopsyra can be found across the Indo-China.
