Received: May 7, 2016 Revised : June 12, 2016 Accepted: June 17, 2016 Published: August 31, 2016 The genus Hauptenia (Hemiptera: Fulgoromorpha: Derbidae) is recorded for the first time in Bangladesh to describe a new species, H. bandarbanensis n. sp. This new species is compared to the seven existing species in this genus but differs from all. It is closer to H. magnifica (Yang & Wu, 1993) (type species) but differs from the latter in the flagellum of aedeagus with 6 processes, and 3 lobes out of 4 produced into processes, bipartite lobe absent (flagellum of aedeagus with 5 processes, and 2 lobes out of 4 produced into processes, one lobe bipartite in H. magnifica). Diagnosis and illustrations of detailed diagnostic characters, including color photographs and line drawings of male genitalia are provided with an identification key to all species of the genus. *Corresponding author: atikentom@pstu.ac.bd Key words: Auchenorrhyncha, Bangladesh, fulgoroidea, new species, planthoppers Introduction The genus Hauptenia was established by Szwedo (2006) based on previously known species of the genus Malenia Haupt from Taiwan that belongs to the tribe Cedusini Emeljanov, 1992 (Hemiptera: Fulgoroidea: Derbidae: Cidusinae). The member of this genus is easily separated from other members in thistribe by head with eyes distinctly narrower than pronotum (Fig. 1B); frons (Fig. 1D) longer in middle line than widest part and shorter than clypeus about 1:1.1–1.46; tegmen (Fig. 1E) longer than widest part about 2.6–3:1, Sc with 2 sectors; wings with vein CuA with two (Yang & Wu 1993: Fig. 40D) or three (Fig. 1F) terminals; spinal formula of hind leg 7–6–5; male genital styles symmetrical, short and stout, dorsobasal projection distad; pygofer with dorsocaudal angle not produced into finger-shaped process; anal segment not distinctly elongated, usually with apex not reaching level of apex of genital styles, anal style turned ventrad or nearly so, slightly notched at apex in lateral view (Rahman et al., 2012).Currently this genus includes the following seven species: H. fellea (Yang & Wu, 1993), H. glutinosa (Yang & Wu, 1993), H. idonea (Yang & Wu, 1993),H. jacula (Yang & Wu, 1993), H. magnifica (Yang & Wu, 1993) (type species), H. palgongsanensis, Rahman, Kwon & Suh, 2012 and H. tripartita, Rahman, Kwon & Suh, 2012 (Bourgoin, 2016). Despite the well-established status of the genus Hauptenia Szwedo in Taiwan and Korea (Yang & Wu, 1993; Rahman et al., 2012), no member of this genus has been noted in Bangladesh. However, during a recent examination of Derbid planthoppers from South- eastern part of Bangladesh, the authors discovered one species of this genus that is clearly separated from all other known species of this genus. The authors consider it to be an undescribed species. The purpose of this study is to describe a new species that present the first record of the genus Hauptenia Szwedo, 2006. Images of diagnostic characteristics and identification key to all species of this genus are provided. Materials and methods Morphological terminology follows Yang and Wu (1993). The term “anal segment” used here means the whole tubular structure of the male genitalia and the “anal style” indicates the process of the anal segment. Spinal formula means the numbers of apical spines of the hind tibiae and 1st and 2nd hind tarsomeres. Dried specimens were used for the description and illustration. External and internal morphology were observed under a stereo microscope (Olympus SZH12) and characters were measured with an ocular micrometer. The length of body was measured from the apex of head to tip of tegmen. Illustrations were scanned ©2016 The Innovative Research Syndicate International Journal of Innovative Research RESEARCH PAPER
