“…However, without data on its population genetics, we refrain from describing this taxon as a subspecies. Moreover, because these morphologically similar Scelimena (including S. melli) are semi-aquatic in behavior and rely on the river they inhabit (Zha et al, 2017), we speculate that these populations are probably restricted to the water catchments that they are found in: S. discalis from India restricted to the Brahmaputra catchment; S. discalis from Thailand restricted to the Mae Khlong (= Mekong) watershed; S. gombakensis sp. nov. restricted to the Sungai Gombak of the Gombak Catchment in Selangor, Malaysia.…”

“…This genus, currently consisting of 23 species, is distributed in the Oriental region (including countries like China, India, Indonesia, Malaysia, Myanmar, the Philippines, and Vietnam) (Cigliano et al, 2018). Little is known about biology and ecology of this genus, except for its importance as an indicator of environment quality (Mahmood et al, 2007;Zha et al, 2017). Members of the genus are relatively large; they are good flyers, swimmers and divers and can survive in semiaquatic environment.…”

Pygmy grasshoppers (Tetrigidae) are a speciose group of complicated taxonomy, with many species requiring clarification on their species boundaries, and more still awaiting discovery. Two new species of Scelimena Serville, 1838 are described: (1) from S. discalis species group S. gombakensis sp. nov. and (2) from S. hexodon species group Scelimena marta sp. nov. Catalogue of Scelimenini genera (15) and species (100) is presented and taxonomy and biogeography of the tribe are discussed. New and resurrected combinations are: Falconius becvari (Buzzetti & Devriese, 2008) comb. nov. (of Gavialidium becvari), Gavialidium carli Hebard, 1930 comb. resurr. (of Bidentatettix carli), Indoscelimena india (Hancock, 1907) comb. nov. (of Scelimena india), Paragavialidium nodiferum (Walker, 1871) comb. nov. (of Platygavialidium nodiferum), Platygavialidium productum (Walker, 1871) comb. nov. (of Gavialidium productum), Scelimena hexodon (Haan, 1843) comb. resurr. (of Hexocera hexodon), Scelimena rosacea (Hancock, 1915) comb. resurr. (of Amphibotettix rosaceus), Tegotettix bufocrocodil (Storozhenko & Dawwrueng, 2015) comb. nov. (of Gavialidium bufocrocodil). New synonyms are: Gavialidium phangensum Mahmood, Idris & Salmah, 2007 syn. nov. (of Eufalconius pendleburyi), Gavialidium philippinum Bolívar, 1887 syn. nov. (of Platygavialidium productum comb. nov.), Hexocera Hancock, 1915 syn. nov. (of Scelimena), Paracriotettix Liang, 2002 syn. nov. (of Scelimena), Paracriotettix zhengi Liang, 2002 syn. nov. (of Scelimena melli), Scelimena mellioides Deng, 2016 syn. nov. (of Scelimena melli), Scelimena wuyishanensis Deng, 2016 syn. nov. (of Platygavialidium sinicum). The genus Scelimena is divided into six species groups. Eucriotettix neesoon Tan & Storozhenko nom. nov. is new name for homonym Eucriotettix guentheri Tan & Storozhenko, 2017. Finally, a tabular key to 15 Scelimenini genera, based on 16 morphological characters, is presented.

Insects are suitable model organisms for functional morphology research, especially in the context of exaptation, when the same morphological trait represents an advantage in disparate niches. Phylogenetically distant groups of pygmy grasshoppers (Orthoptera: Tetrigidae) have various pronotal projections, defining their general appearance, i.e., body shape. However, pronotum shape has never been related to niche occupation in these insects, thus the aim of this study is to investigate the relationship between body shape and macrohabitat adaptation in Scelimeninae, a group of Asian and Papuan tetrigids encompassing amphibious and corticolous (bark-dwelling) representatives. With the use of geometric morphometrics and phylogenetic comparative methods, two morphological and functional groups were distinguished, with the body shape exhibiting a significant phylogenetic signal. The first group consists of elongated amphibious taxa (Scelimenini tribe) with highly uniform pronotum morphology, likely due to strong selection for streamlined body shape. Stouter corticolous taxa (Discotettigini tribe) exhibit more conspicuous body shape variability, possibly increasing camouflage efficiency in tree bark habitats. Ecological divergence associated with macrohabitat adaptation may thus have been the primary driver of speciation in this insect group, but the evolutionary constraints leading to this divergence are still to be identified.

A brief preliminary revision of the genus Scelimena Serville, 1838 (Tetrigidae: Scelimeninae: Scelimenini) from PR China is presented. Scelimena pyrroma Lao, Kasalo, Gao, Deng et Skejo sp. nov. is described from Hainan, Ding'an, based on a female holotype and a male paratype, and an additional photograph of a female in the natural habitat from Wuzhi National Nature Reserve (Wuzhi-shan Mountain). Specimens of this new species were hitherto reported from Hainan as S. dentiumeris (Hancock, 1907), a species endemic to Borneo. The new species is easily distinguished from its congeners by the presence of prominent yellow humeral tubercles and by the lateral pronotal spines directed forwards. The new species from Hainan and S. chinensis (Hancock, 1915) from Vietnam are assigned to Scelimena producta species group based on the similarity with S. producta (Serville, 1838), which is characterized by the humeral angles with tubercles, wide vertex, and toothed ventral margins of hind femora, while S. boettcheri Günther, 1938 from Palawan is assigned to Scelimena discalis species group, based on the tuberculated median carina. Scelimena dammermanni Günther, 1938, stat. nov., hitherto regarded as a subspecies of S. producta, is elevated to a species level because it lacks ventral spines on the hind legs, present in all S. producta individuals. New synonymy is established: Scelimena melli Günther, 1938, =Scelimena brevispina Cao et Zheng, 2011, syn. nov.; =Scelimena wulingshana Zheng, 1993, syn. nov.; =Eufalconoides guizhouensis Zheng et Shi, 2006, syn. nov. Scelimena melli, S. guangxiensis Zheng et Jiang, 1994 from southern China and S. kempi (Hancock, 1915) from NE India are assigned to S. bellula species group on the basis of similarity to S. bellula Storozhenko et Dawwrueng, 2015. Further research should determine whether S. spicupennis Zheng & Ou, 2003 represents a valid species or a synonym of another Scelimena species, as well as if S. nitidogranulosa Günther, 1938 and S. guangxiensis Zheng & Jiang, 1994 represent separate species or whether they are conspecific. Specimens of S. nitidogranulosa from Hainan reported by Liang & Zheng in 1998 are in fact Platygavialidium sinicum Günther, 1939. Scelimena songkrana Zha et Wen, 2017 is recorded from China for the first time. A key to Scelimena species found in PR China is also provided.
