Genus Eufalconius Günther, 1938

Eufalconius: Günther 1938a, 1955 , Blackith 1992, Yin et al. 1996, Otte 1997, Skejo & Bertner 2017.

Hancockitettix: Storozhenko & Pushkar 2017 , Skejo & Bertner 2017.

Type species: Eufalconius pendleburyi Günther, 1938

Composition and distribution. Monotypic genus, its only species ( E. pendleburyi ) inhabiting Peninsular Malaysia.

Notes. This monotypic genus from Malay Peninsula is characteristic among Scelimenini in having a short pronotum (brachypronotal state) that led Storozhenko & Pushkar (2017) to conclude that it belongs to Cladonotinae . However, the genus has all the Scelimenini characters, and is closely related to Paragavialidium and Platygavialidium . The genus is characteristic in (I) very wide metalateral plates, that are of the same width as ventrolateral projections of the paranota and (II) females with flattened distal segment of the hind tarsi and (III) lack of ventrolateral spine. Euflaconius pendleburyi Günther, 1938 may belong to Paragavialidium but such an act would require future examination and better understanding of Paragavialidium . Furthermore, Gavialidium phangensum Mahmood, Idris & Salmah, 2007 syn. nov. ( Mahmood et al., 2007: Fig. 6 ), described from Kuala Lompat: Pahang (Peninsular Malaysia) is conspecific with Eufalconius pendleburyi Günther, 1938 (see Storozhenko & Pushkar, 2017 and Skejo & Bertner, 2017), and is synonymized with the latter. The two are identical in morphology (especially in characteristic wide shoulders, strong triangular ML projection), and distribution of G. phangensum syn. nov. fits into the distribution area of E. pendleburyi .
