Diagnosis

P. longicauda (Figs 1, 2) differs from other congeners, with the exception of an undescribed species from Papua New Guinea (Kostro-Ambroziak, unpubl.), in the presence of a pleural carina (Fig. 2d). This species is distinguished from other Phytodietus species known from Thailand also by the following features: epomia present (Fig. 2c), distinct wrinkles on propodeum and metapleuron (Fig. 2d) and a constriction between the base and spiracles of the first metasomal segment (Fig. 3a).

Distribution

P. longicauda is one of the most widely distributed species of Phytodietus and has already been recorded in China, India, Japan, Myanmar, Russia and Taiwan ( Yu et al. 2012).

Biology

P. longicauda probably has more than one generation per year. It has been recorded in: May in India ( Kaur and Jonathan 1979) and Thailand, June in Myanmar ( Kasparyan 1998), July in Amami-Oshima island within the Ryukyu Archipelago (Japan) ( Momoi 1970), August in Russia ( Kasparyan and Tolkanitz 1999), October in Japan ( Kaur and Jonathan 1979), December in Taiwan ( Cushman 1933) and Japan ( Kasparyan and Tolkanitz 1999). P. longicauda also occurs over a wide range of altitudes and has been noted at 2000 m a.s.l. in Myanmar ( Kasparyan 1998), 1700-2286 m a.s.l. in India ( Kaur and Jonathan 1979), 300 m a.s.l. in Amami-Oshima island ( Momoi 1970) and 735 m a.s.l. in Thailand. There are no current host records.
