Diagnosis. One of four Abscondita with pale dorsum and black elytral apices (Ballantyne et al. 2013 fig. 2). Distinguished from both Abs. chinensis and Abs. terminalis by the pale terminal abdominal tergites and its larger size (males may reach 13.5 mm and females 16.5 mm); differing from Abs. perplexa in its much larger size and in having a pale abdomen ( perplexa usually has dark markings on at least V5). Females macropterous (Ballantyne et al. 2013 fig. 2 C, D). Larvae with short spines over dorsal surface and mandibles with two inner teeth (Ballantyne et al. 2013 figs 2 E, 4; Fu 2014: 100).

Remarks. Fu (2014: 100) illustrated the luminous male and female pupae. Specimens from Thailand are longer than those recorded by Ballantyne et al. (2013). Males were 12.2–13.5 mm long compared to 10.3–12.9 mm long, females 13.6–16.5 mm long to 11.6–14.0 mm long. Females have the abdominal ventrites anterior to the LO brown (yellow in Chinese specimens). Males in the Nak-eiam collection have small pieces to the sides of the aedeagal sheath tergite with a transverse band connecting them. Similar bands are seen in other members of this genus.
