Pseudopsyra Hebard 1922

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.
