Leberis diaphanus (King, 1853) View in CoL
Common species in Cat Tien ( Sinev & Korovchinsky 2013). Species was present in all samples from locality 7, and in most samples from locality 1. Several adult males and ephippial females were found in locality 7 on 15.02.2018; ephippial females were also found in locality 1 on 5.12.2017.
Parthenogenetic females of the species were studied by Sinev et al. (2005) and Neretina & Sinev (2016). Second species of the genus, Leberis punctatus (Daday, 1898) , was found in South-East Asia recently ( Neretina & Sinev 2016), but all studied females in our material have IDL setae morphology typical for L. diaphanus ( Fig. 6B View FIGURE 6 ). Morphology of studied parthenogenetic females fully agrees with the previous descriptions. Males of this species were never reported from nature in South-East Asia, but were obtained by Sinev & Sanoamuang (2011) in culture by hormonal induction. Single ephippial female was found in a population from Borneo ( Sinev & Yusoff 2018). Ephippial females were studied using SEM for the first time.
Ephippial female. Body ( Fig. 5 View FIGURE 5 D–E, 6A–B) high oval, similar in shape to that of parthenogenetic female. Ephippium subtriangular, moderately high, with distinctive dorsal keel and weakly defined egg locules, with sculpture in shape of irregularly spaced depressions with small dots inside them. In preserved specimens ephippium color is yellow-brown.
Male. Morphology of males from studied population ( Fig. 5 View FIGURE 5 F–G, 6C–F) agrees with that of hormonally induced males ( Sinev & Sanoamuang 2011: Fig. 3 View FIGURE 3 ), but basal spine of postabdomen ( Fig. 5G View FIGURE 5 , 6D View FIGURE 6 ) is slightly shorter, and terminal aesthetascs of antennule ( Fig. 6E View FIGURE 6 ) are somewhat longer. These differences are within normal variability of males in Aloninae .
