Sažetak
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.
