Abstract: Long-headed pygmy grasshoppers (genus Ophiotettix Walker, 1871) from the New Guinean region (New Guinea and adjacent islands) are taxonomically and biogeographically reviewed. For Ophiotettix and the morphologically similar genera Paraspartolus Günther, 1939, Spartolus Stål, 1877 and Threciscus Bolívar, 1887 a new tribe is erected, Ophiotettigini trib. nov. This tribe is close to Clinophaestini Storozhenko, 2013, which is placed here also under Metrodorinae. Bufonidinae syn. rev. are regarded to be synonymous with Batrachideinae, not Cladonotinae, as previously considered. Statuses of currently known taxa of Ophiotettix are reviewed. The genus now includes 40 species, seven of them previously described: O. buergersi Bolívar, 1929, O. cygnicollis Walker, 1871, O. limosina (Snellen van Vollenhoven, 1865), O. lorentzi Bolívar, 1929, O. modesta Bolívar, 1929 stat. rev., O. scolopax Bolívar, 1929, O. westwoodi Bolívar, 1929 stat. rev. 33 new species are described and illustrated, namely: O. amberiana sp. nov., O. bewana sp. nov., O. bomberaiensis sp. nov., O. brevicollis sp. nov., O. cheesmanae sp. nov., O. depressa sp. nov., O. filiforma sp. nov., O. flyriveriensis sp. nov., O. fritzpahli sp. nov., O. hansscholteni sp. nov., O. imbiana sp. nov., O. kaitani sp. nov., O. karimuiensis sp. nov., O. katharinae sp. nov., O. luce sp. nov., O. meggy sp. nov., O. mountnokensis sp. nov., O. parvicollis sp. nov., O. projecta sp. nov., O. pulcherrima sp. nov., O. pushkari sp. nov., O. quateorum sp. nov., O. rebrinae sp. nov., O. roesleri sp. nov., O. rohwedderi sp. nov., O. sanguinea sp. nov., O. schapinae sp. nov., O. stallei sp. nov., O. storozhenkoi sp. nov., O. subbrevicollis sp. nov., O. telefominensis sp. nov., O. tenuis sp. nov., and O. toxopei sp. nov. An annotated identification key to species is provided. Antennal morphology (especially morphology of five apical segments) is diagnostically important in the taxonomy of this group and provides the best morphological character for species delimitation. Function of modified antennae is not fully understood. Differences between species exist also in head morphology, facial colouration, and morphometrics. Pygmy Giraffhoppers are a diverse group occupying most biogeographical regions of New Guinea North of the Central range, while only few species inhabit areas south of the central range.

Key words: Orthoptera, Tetrigidae, pygmy grasshoppers, Discotettiginae, New Guinea, taxonomy, new species, widened antennal segments, long head, horn.

Introduction extended covering the abdomen, lack of tympana, lack of arolium between the claws, the tarsal formula Pygmy grasshoppers (family Tetrigidae), an being 2-2-3 and first thoracic sternum modified into old lineage of Triassic origin, are one of the most a collar-like structure called sternomentum (Skejo diverse living Orthoptera groups, with more than 2016). 1900 species described to date (Song et al. 2015). The island of New Guinea including its adjacent The highest concentration of species is found in satellite islands like Gebe, Waigeo and Yapen has tropical regions, but there are representatives in a very diverse pygmy grasshopper fauna. Species all biogeographical realms, from taiga to tropical inhabiting this region show an extremely large rainforests, exception being Antarctica and New variability of morphological structures like antennae, Zealand (Tumbrinck 2014a). Pygmy grasshoppers head, palpi, pronotum, legs and abdomen as well can be easily recognized by their small body size as a high number of endemic taxa. Hitherto about (usually smaller than 1.5 cm), their pronotum being 30 genera and 100 species were recorded from

New Guinea (Tumbrinck 2014a, 2014b, 2015; Materials and methods Cigliano et al. 2017). One of the morphologically most striking and Material interesting groups of pygmy grasshoppers is the genus Ophiotettix Walker, 1871 (formerly known This study has been based on an examination also as Tetricodina Westwood, 1874 and Tettigodina of the majority of the hitherto published specimens Bolívar, 1887). It consists of colourful long headed besides a large number of additional specimens pygmy grasshoppers that, out of endearment, could (altogether over 750 specimens). All specimens be named ‘Pygmy Giraffehoppers’. In the past the that arelisted have been examined unless stated genus had been assigned both to Discotettiginae otherwise. Paratypes have been individually (Hancock 1907) based on the presence of numbered (3/14: paratype number 3 in a series widened subapical antennal segments in certain of 14). Abbreviations used for depositories species (e.g. O. cygnicollis Walker, 1871, the type are presented below. Original label data are species of the genus) and to Metrodorinae (e.g. supplemented with authors’ comments in square Günther 1939) based on morphological similarity brackets. Paraspartolus Günther, 1939, Spartolus Stål, 1877 and Threciscus Bolívar, 1887 but is currently Photography without clear placement within Tetrigidae. Only two Ophiotettix species (O. limosina and Various cameras using various lenses have O cygnicollis) had been described when Bolívar been used to take photos, all in macro mode by (1929) made the first revision of the genus, using a stacking system with integrated scale bar describing three additional species (O. buergersi, or with a macro-lens and millimetre paper. No O. lorentzi and O. scolopax) and two subspecies post-processing of photographs has been done. (O. buergersi modesta and O. b. westwoodi). Since Millimetre paper was placed close to photographed Bolívar’s revision, Günther (1938a, 1939, 1955) specimen and subsequently used to construct a added new localities for certain species, included scale bar included in the photograph, after which Ophiotettix in his identification key and discussed the millimetre paper was deleted. the taxonomic position of the genus, but did not describe new taxa or change the status of any of Morphology the taxa described by then. Based on the examination of over 750 specimens The morphology of head, pronotum, legs, the current study, while re-evaluating the status of and genitalia follows Devriese (1991, 1999) and the described species, resulted in the recognition Tumbrinck (2014a) (Plate 104 figs 1-4). and description of an additional 33 new species. Results from the current study were compared One possible new species photographed by various with previous studies dealing with morphology of Orthopterologists in the Muller Range (Papua New Ophiotettix (Bolívar 1887, 1929; Hancock 1907; Guinea) is not described here because of lack of Günther 1939). The current study resulted in a physical specimens. Results from the current study new diagnosis of the genus and a more detailed were compared with previous studies dealing with description of members of the genus Ophiotettix, morphology of Ophiotettix (especially Bolívar 1887, including characters previously used as well as 1929; Hancock 1907; Günther 1939). The current numerous characters not yet used in detail until study resulted in a new diagnosis of the genus and now. In addition the current study led to a detailed a more detailed description of members of the generic description with notes on variability genus Ophiotettix, including characters previously of characters and with comments on value/ used as well as numerous characters not yet used usefulness of certain characters in this group of in detail until now. In addition the current study pygmy grasshoppers. Characters important for led to a detailed generic description with notes distinction of hitherto described species are related on variability of characters and with comments on to head morphology and to morphometrics, thus for value / usefulness of certain characters in this group the genus a detailed morphological description is of pygmy grasshoppers. An identification key to all presented, while for each species, only diagnostic known species is provided. In addition Ophiotettix descriptions of the characters essential for accurate is compared with morphologically similar genera in identification are presented. the Metrodorinae and the morphological diversity Antennal morphology is the most relevant in particular of the antennae is discussed. character in separation of Ophiotettix species.

The genus Ophiotettix is one of the nomenclaturally oldest Tetrigidae genera, only Results twelve genera being described before it. It is the very first endemic genus of New Guinea Placement of Ophiotettix in Tetrigidae to be described. Morphologically Ophiotettix is one of the most striking genera of pygmy Since establishment of the basis for the current grasshoppers. Up to now Ophiotettix was assigned Tetrigoidea taxonomy by Bolívar in 1887, not a lot to the Discotettiginae. However Discotettiginae has changed. After 1887 only few new subfamilies are identical with Scelimeninae (Skejo, Pushkar & and tribes were established (e.g. Discotettiginae, Tumbrinck in press). Ophiotettix does not belong Bufonidinae), serving primarily for better to Scelimeninae. Genera such as Discotettix identification and not being evolutionary units. The Costa, 1864, Gavialidium Saussure, 1862, only exception is subfamily Batrachideinae that Paragavialidium Zheng, 1994, and Kraengia can be regarded separate family Batrachideidae.
