E-mail: [email protected] Abstract Two new genera, Parapelerinus gen. nov., and Conversifastigia gen. nov. with three new species, P. ensatus sp. nov., P. emarginatus sp. nov., and C. gressitti sp. nov. are described from Southern China. Principal taxonomic and diagnostic characters including structure of head, tegmen, stridulatory file of male, male and female apex are illustrated. Parapeleri- nus is distinguished from other related genera by the sword-like ovipositor, which is very uncommon in the subfamily Phaneropterinae. The species of Conversifastigia gen. nov. possess a pyramidal fastigium frontis, which is not present in related genera. Key words: new genus, new species, Phaneropterinae, China Introduction Southern China is characterized as sub-tropical region with very rich flora and fauna, in which there is high biodiversity of tettigoniid species because of diversity of habitats and complex topography. The Phaneropteri- nae, the largest subfamily in the Tettigoniidae, which numbers 31 genera and 106 species in Jin & Xia’s list (1994), was systematically studied in Southern China in the last century. Our recent studies, bring the number up to 40 genera and 180 species in the Phaneropterinae. These studies include the description of 4 new genera and 33 new species (Gorochov & Kang, 2002, 2004; Liu et al, 2004; Liu & Kang, 2006a, b; 2007a, b, c). We believe that with more specialists working on the fauna of this region, more species remain to be discovered. Here, we describe two new genera and three new species from Southern China. One new genus Parapelerinus gen. nov. is described to include two new species, P. e n sa tu s sp. nov., occurring in the primal forests of Guangxi Province and Hainan Island, and P. emarginatus sp. nov. from Fujian Province. Parapelerinus gen. nov. is similar to Pelerinus Bolivar and Arnobia Stål, but differs by many morphological characters. Field col- lections on Hainan Island, reveal that adults of P. en s a tu s sp. nov. occur in May or November, and, however, we didn’t find any specimens of this species in August or September. The other new genus Conversifatigia gen. nov. with one new species C. gressitti sp. nov., is distributed in Guangdong Province. The fastigium fron- tis of Conversifastigia gen. nov. is inversely pyramidal, with truncated dorsal apex distinguishes it from other related genera, such as Letana Walker and Qinlingea Liu & Kang. All specimens were examined with a Leica MZ12.5 microscope, drawings were made with Leica MZ12.5 with a drawing mirror, and photographs of stridulatory areas were made with a Canon Powershot 50 digital camera fixed on Leica MZ12.5 microscope. Material comes from the following two depositories: Insect Collection of Institute of Zoology, the Chi- nese Academy of Sciences, Beijing, China (IZAS); and Institute of Entomology, the Chinese Academy of Sci- ences, Shanghai, China (IEAS).

Diagnosis: Fastigium verticis narrower than first segment of antenna. Pronotal disc with surface of prozona smooth, without lateral carina. Tegmen slightly widened in middle, with radical sector bifurcated. Anterior coxae armed; anterior tibiae with open tympanum on both sides. Anterior femur with genicular lobe round, median and posterior femora each with a small spine on lower genicular lobe. Male tenth abdominal tergite normal, not produced. Male concealed genitalia with a pair of sclerites. Male subgenital plate without styli. Female ovipositor slender, sword-shaped, with dorsal and ventral margins smooth; apex pointed. Description: Head ovoid, occiput convex and smooth. Fastigium verticis well-produced, dorsally sulcate, distinctly narrower than first segment of antenna, with apex approximately rounded. Fastigium frontis inversely ovoid; dorsal apex slightly narrower than fastigium verticis, separated by a rather wide gap. Com- pound eye wide elliptical, obliquely set, greatly bulging, ventral margin extending slightly beyond ventral margin of antennal scrobe (Figs. 1–8). Pronotum slightly widened posteriorly; disc of pronotum with anterior portion slightly convex, posterior third flattened; anterior margin slightly concave, posterior margin obtuse with a middle notch; pronotum with lateral margin rounded and without lateral carinae (Figs. 3, 6). Lateral lobe of pronotum much higher than long; humeral sinus distinct (Figs. 2, 5, 8). Prosternum unarmed. Meso- and metasterna more or less transverse, their lobes rather small, rounded. Anterior coxae armed with a small sharp spine; anterior tibiae dorsally sulcate, with open tympanum on both sides; widened at and abruptly con- stricted below tympana (Fig. 12). Anterior and median femora with spines on ventro-anterior margin; poste- rior femur with spines on both ventral margins. Anterior femur with genicular lobe round (Fig. 12), median and posterior femora each with a small spine on the lower genicular lobe (Figs. 14, 16). Anterior tibiae with or without dorsal spines on anterior margin; median tibiae with dorso-posterior spines; posterior tibiae with dor- sal spines on both sides. Tegmen slightly translucent, with regular veinlets; costa indistinct; subcostal vein and radial vein joined at base, then separated but closely abutted together till before apical part of tegmen; radical sector bifurcated before middle of tegmen; apex of tegmen rounded. Male stridulatory area (Figs. 18–21) with posterior margin sinuate; male right stridulatory area with distinct triangular mirror (Figs. 19, 21). Male terminalia (Figs. 24–33). Tenth abdominal tergum normal, slightly concave in middle; apex broad truncated. Epiproct triangular, with apex obtuse. Cerci long, gradually tapering; apex pointed, various. Sub- genital plate elongate, with or without emargination at the apex; without styli (Figs. 34, 35). Concealed geni- talia with a pair of sclerites, species distinctive (Figs. 28–33). Female terminalia. Ovipositor sword-shaped, slender, with dorsal and ventral margins smooth; apex pointed (Fig. 31). Subgenital plate distinguished (Fig. 30). Discussion: The new genus resembles the genus Pelerinus Bolivar in the general features, including head, lateral lobe of pronotum, tympana, and wing, but differs in the structure of genicular lobes of each femur, the shape of the tegmen and hind wing, the shape of female ovipositor, and the male abdominal apex. The male stridulatory apparatus, and the male tenth abdominal apex except for the concealed genitalia, resemble the same structures in Arnobia Stål. This new genus differs from Arnobia in the structure of tympana on fore tib- iae and the concealed sclerotized genitalia. Etymology: The name Parapelerinus is named suggesting its relationship with Pelerinus; masculine gen- der. Distribution: China. 1. Parapelerinus ensatus sp. nov.

  • Orthoptera Species Checklist of Bukit Timah Nature Reserve in the Zoological Reference Collection, Singapore
    Gardens’ Bulletin Singapore 71(Suppl. 1):331-338. 2019 331 doi: 10.26492/gbs71(suppl.1).2019-13 Orthoptera species checklist of Bukit Timah Nature Reserve in the Zoological Reference Collection, Singapore M.K. Tan Department of Biological Sciences, National University of Singapore, 14 Science Drive 4, 117543 Singapore [email protected] ABSTRACT. While work on Orthoptera in Singapore is not lacking, there is no species checklist for the species found within the Bukit Timah Nature Reserve (BTNR). Here, a checklist of orthopterans in the reserve is given based on specimens deposited in the Zoological Reference Collection of the Lee Kong Chian Natural History Museum, Singapore. In total, 83 species, 30 from the suborder Caelifera (grasshoppers and relatives) and 53 from the suborder Ensifera (crickets, katydids, and relatives), are recorded from the reserve. Keywords. Crickets, diversity, grasshoppers, insects, katydids, richness Introduction There are more than 2000 species of grasshoppers, crickets, and katydids in Southeast Asia (Cigliano et al., 2018; Tan et al., 2017c). Collectively known as the Orthoptera, the grasshoppers belong to the monophyletic suborder Caelifera, whereas the crickets and katydids belong to the other monophyletic suborder Ensifera (Song et al., 2015). These insects include a very few species that are notorious pests (Willemse, 2001). However, owing to the richness in species and diversity of form, orthopterans provide more ecosystem services than might have been expected. They can function as potentially mutualistic pollinators (e.g., Tan & Tan, 2018), predators of other pest species, prey to charismatic species (e.g., Fung et al., 2018) and potential ecological indicators (e.g., Tan et al., 2017a).

E-mail: [email protected] Abstract Inclusion of the tribe Holochlorini has been questionable, for its complicated history and its controversial important diag- nostic character about structure of tibial tympana. Here we briefly introduce its history and summarize its inclusion in the world and in China. We also introduce a newly recorded genus from China, Arnobia, and other two genera in the tribe, Psyrana and Phaulula, provide a list of Chinese species for the three genera, separately, together with the key to species of the three genera. At the same time, we describe seven new species to science in the Holochlorini, i.e., Arnobia hainan- ensis sp. nov., Arnobia guangxiensis sp. nov., Phaulula apicalis sp. nov., Psyrana magna sp. nov., Psyrana heptagona sp. nov., Parapsyra brevicauda sp. nov., and Sinochlora semicircula sp. nov. Diagnostic illustrations are presented. Key words: katydids, Holochlorini, Orthoptera, new species, China Introduction Bei-Bienko (1954) combined Brunner von Wattenwyl’s (1878) Psyrae and Holochlorae as the tribe Holochlorini and provided detailed description and diagnostic characters of the tribe. At present, inclusion of the tribe Holochlo- rini needs to be carefully checked out. On one hand, the history of the two groups Psyrae and Holochlorae is very complicated after they were established.

Email: [email protected] Abstract The Phaneropterinae, or commonly known as the bush katydids, are among the most speciose katydids in the world. The bush katydids have interesting life histories but little is known about species from Southeast Asia. The source of problem may lie in the lack of sampling and revised taxonomic knowledge. The paper reports a species checklist of Phaneropteri- nae from Singapore. In total, 30 species were recorded from Singapore, eight of which may be locally extinct. Each species was also annotated with known life history information or taxonomic remarks, whenever possible. The female of Phaulula malayica was also described for the first time. An illustrated key to species from Singapore was also provided to assist in species identification. Key words: Orthoptera, Phaneropterinae, Singapore, annotated checklist, illustrated key Introduction The Phaneropterinae, or commonly known as the bush katydids, are among the most speciose katydids in the world. The bush katydids have interesting life histories. Nymphs of many species are colourful and some mimic other insects and also change their model organism as they grow through the different instars (Rentz, 2010).

  • Orthoptera: Tettigoniidae: Phaneropterinae), with Description of Seven New Species from China
    Zootaxa 2931: 35–52 (2011) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ Article ZOOTAXA Copyright © 2011 · Magnolia Press ISSN 1175-5334 (online edition) Brief Summary of Holochlorini (Orthoptera: Tettigoniidae: Phaneropterinae), with Description of Seven New Species from China CHUN-XIANG LIU Key Laboratory of Zoological Systematics and Evolution, Institute of Zoology, Chinese Academy of Sciences, Beijing 100080, China. E-mail: [email protected] Abstract Inclusion of the tribe Holochlorini has been questionable, for its complicated history and its controversial important diag- nostic character about structure of tibial tympana. Here we briefly introduce its history and summarize its inclusion in the world and in China. We also introduce a newly recorded genus from China, Arnobia, and other two genera in the tribe, Psyrana and Phaulula, provide a list of Chinese species for the three genera, separately, together with the key to species of the three genera. At the same time, we describe seven new species to science in the Holochlorini, i.e., Arnobia hainan- ensis sp. nov., Arnobia guangxiensis sp. nov., Phaulula apicalis sp. nov., Psyrana magna sp. nov., Psyrana heptagona sp. nov., Parapsyra brevicauda sp. nov., and Sinochlora semicircula sp. nov. Diagnostic illustrations are presented. Key words: katydids, Holochlorini, Orthoptera, new species, China Introduction Bei-Bienko (1954) combined Brunner von Wattenwyl’s (1878) Psyrae and Holochlorae as the tribe Holochlorini and provided detailed description and diagnostic characters of the tribe. At present, inclusion of the tribe Holochlo- rini needs to be carefully checked out. On one hand, the history of the two groups Psyrae and Holochlorae is very complicated after they were established.
