( Fig. 9View FIGURE 9)

Falconius: Bolívar 1898  , Hancock 1907a, Kirby 1910, Günther 1938a, Yin et al. 1996, Otte 1997, Jiang & Zheng 1998, Zheng 2005, Zheng et al. 2006, Deng et al. 2007, 2009, Storozhenko 2014, Zheng 2014, Deng 2016, Storozhenko 2017.

Type species: Criotettix clavitarsis Bolívar, 1887 

Composition and distribution. 20 species distributed in PR China: Yunnan ( F. undatifemora  ), Guangdong ( F. annulicornis  , F. longidorsalis  ), Guangxi ( F. guangxiensis  , F. longicornis  ) and Hainan ( F. hainanensis  ), Vietnam ( F. tschernovi  ), Myanmar ( F. inaequalis  ), Thailand ( F. inaequalis  ), Cambodia ( F. elephant  ) on Mentawai Islands Sipora ( F. clavatus  , F. gestroi  , F. karnyi  ) and Siberut ( F. karnyi  ), Sumatra ( F. becvari  comb. nov.), Java ( F. bedoti  ), Borneo ( F. clavitarsis  , F. deceptor  , F. dubius  , F: planitarsus  , F. pseudoclavitarsis  ), and the Philippines: Palawan Isl. ( F. palawanicus  ). Since we did not review this genus, we only present list of its species, with brief discussion on its type species ( F. clavitarsis  ) and F. becvari  comb. nov.

Notes. The genus currently includes 20 species and its taxonomy is confusing. The genus was established by Bolívar (1898) for a Criotettix  species ( F. clavitarsis ( Bolívar, 1887)  , type locality Borneo) and two new species ( F. clavatus Bolívar, 1898  and F. gestroi Bolívar, 1898  ) in which females have widened third (distal) segment of the hind tarsi. Since this character is present also in Eufalconius  , we are not sure if it represents apomorphic or homoplastic character. Members of this genus are smaller than most Scelimenini  , have visible interhumeral carina (evident only in Euscelimena  and some Tegotettix  species within Scelimenini  ), lack pronotal projections homologous to that of Scelimenini  , despite of having sometimes wrinkled pronotum with elevations, and the antennal grooves and paired lateral  ocelli situated higher. Despite preliminary examination of species with photographs in Orthoptera  Species File Online ( Cigliano et al. 2018), this remains unclear. Within the genus Falconius  , large variability in the morphology of the lateral  lobes can be observed; and ventrolateral projection can be (1) sharp spine strongly directed forwards ( F. bedoti  , F. clavitarsis  , F. dubius  , F.guanxiensis  , F. hainanensis  , F. longicornis  , F. longidorsalis  , F. tschernovi  and F. undatifemura  ), (2) long transverse spine gently curved forwards ( F. clavatus  and F. palawanicus  ), (3) short spine directed forwards ( F. pseudoclavitarsis  ), short transverse spine ( F. annulicornus  and F. deceptor  ), (4) short tooth-like spine ( F. elephant  ), or (5) truncated ( F. becvari  comb. nov., F. gestroi  , F. inaequalis  , F. karnyi  , F. planitarsus  ) (Storozhenko 2017). Gavialidium becvari  is transferred here, thus Falconius becvari ( Buzzetti & Devriese, 2008)  comb. nov. This genus is morphologically also similar to Arulenus Stål, 1877  and Mazarredia Bolívar, 1887  . Revision of the genus was published recently ( Deng et al. 2009), so we do not assess taxonomy of all the species, especially from Chinese, in details.
