Discussion. Gryllotalpa hirsuta , along with its synonyms, is in need of modern re-examination and redescription. Gryllotalpa siamensis Giebel, 1870 was noted as a junior synonym of Gryllotalpa hirsuta by Henri de Saussure ( 1877) (Eades et al., 2013). The remarks are however vague and differences in their genitalia were not provided. Here, photographs of three male specimens from DORSA were examined: two labelled Gryllotalpa hirsuta (AGryhirS01 and BG00071S01) and one labelled Gryllotalpa siamensis (AGrysiaS01) ( Figs. 5 & 6 ). Male tegmina appear similar ( Fig. 6 ). It was also mentioned in Saussure ( 1877) that Gryllotalpa hirsuta has shorter wings (tegmina?), “les ailes (élytres?)”, than Gryllotalpa siamensis but photographs from DORSA do not show any clear differences ( Fig. 6 ). Gryllotalpa longipennis Saussure, 1877 was redescribed by Saussure ( 1877). Subsequently, it is placed as a subspecies ( Gryllotalpa hirsuta longipennis Chopard, 1931 ) without further discussion (Chopard, 1931). Hence, no conclusion may be made to affirm if these synonyms are truly distinct species until a reexamination of the types. Whenever possible, acoustic analysis may help solve this taxonomic problem.

Based on the photographs from DORSA, a modern redescription of the male tegminal venation and genitalia of Gryllotalpa hirsuta is provided in Table 1 . Comparison with Gryllotalpa fraser sp. n. and Gryllotalpa nymphicus indicates that the three species are distinct ( Table 1 ).
