Abstract

The derbid planthopper genus Hauptenia Szwedo, 2006 is reviewed. Two new species from China, H. beibengensis Sui & Chen, sp. nov. and H. daliensis Sui & Chen, sp. nov., are described and illustrated. A third species, H. tripartita Rahman et al., 2012, is recorded from China for the first time. An updated checklist and identification key to all ten known species of the genus Hauptenia are provided.

Introduction

The planthopper family Derbidae (Hemiptera, Fulgoromorpha) was established by Spinola in 1839, containing 22 tribes in three subfamilies (Bourgoin 2023), eight tribes, 38 genera, and 156 species of which are known in China (Yang and Wu 1994; Sui and Chen 2019; Bourgoin 2023). Most of these taxa are distributed in the Oriental bioregion, especially in southern China.

In the Breddiniolinae Fennah, 1950, Cedusini Emeljanov, 1992 and subtribe Cedusina Emeljanov, 2008, the genus Hauptenia was established by Szwedo (2006) for five Chinese species (previously in Malenia Haupt, 1924) and with Malenia magnifica Yang & Wu, 1994 as its type species. Rahman et al. (2012) described two Korean species and Jhan et al. (2016) described one Bangladeshi species, bringing the total of known species to eight: H. bandarbanensis Jhan & Rahman, 2016, H. fellea (Yang & Wu, 1994), H. glutinosa (Yang & Wu, 1994), H. idonea (Yang & Wu, 1994), H. jacula (Yang & Wu, 1994), H. magnifica (Yang & Wu, 1994), H. palgongsanensis Rahman, Kwon & Suh, 2012, and H. tripartita Rahman, Kwon & Suh, 2012.

Herein, two new species, Hauptenia beibengensis Sui & Chen, sp. nov. and H. daliensis Sui & Chen, sp. nov., are described and illustrated from China, bringing the total number of this genus to ten. One species, H. tripartita Rahman et al., 2012, is recorded from China for the first time, and a key is provided to all ten species of Hauptenia.

Materials and methods

The morphological terminology follows Bourgoin (1987), Bourgoin and Huang (1990) and Yang and Wu (1994). Body length was measured from apex of vertex to tip of fore wing by KEYENCE VHX-1000E system. The standard terminology of venation follows Bourgoin et al. (2015). Dried specimens were used for the descriptions and illustrations. External morphology was observed under a stereoscopic microscope and all measurements were done with an ocular micrometer. Color pictures for adult habitus were obtained by the KEYENCE VHX-6000 system. Genital segments were macerated in 10% NaOH and drawn from preparations in glycerin jelly using a Leica MZ 12.5 stereomicroscope. Illustrations were scanned with a Canon CanoScan LiDE 220 and imported into Adobe Photoshop CS5 for labeling and plate composition. The dissected genitalia were preserved in glycerin in small plastic tubes pinned together with the specimens.

The type specimens and examined specimens are deposited in the Institute of Entomology, Guizhou University, Guiyang, Guizhou Province, China (GUGC).

Discussion

The genus Hauptenia Szwedo, 2006, belongs to the tribe Cedusini (Hemiptera: Derbidae: Breddiniolinae), which is characterized by sensory pits on head and on wings absent, subantennal process well developed, jugal margin of hind wings without stridulatory plate, and tibia of hind leg without lateral spine (Emeljanov 1996). The tribe Cedusini comprises the subtribes Cedusina Emeljanov, 1992 and Eocenchreina Emeljanov, 2008. The obvious difference between them is that species of Cedusina have cixiid venation of the clavus (fore wing with joined claval veins Pcu + A1 reaching commissural margin of fore wing, reaching vein A2), and species of Eocenchreina have achilid venation of the clavus (fore wing with joined claval veins Pcu +A1 reaching claval suture, reaching CuP, near apex of clavus). As the subtribe Eocenchreina was erected for Cedusini with the achilid venation of the clavus, the genus Hauptenia was indirectly placed in the subtribe Cedusina by Emeljanov (2008). Morphologically, the whole subtribe Cedusina are very similar externally, but Hauptenia may be easily distinguished from other genera of Cedusina by the short and stout gonostyli, the pygofer with its dorsocaudal angle not produced, and the spinal formula of the hind leg 7–6–5 (Szwedo 2006; Rahman et al. 2012). In terms of geographical distribution, Hauptenia may be closely related to Produsa and Muiredusa in the same subtribe Cedusina. However, for the exact relationships within the subtribe Cedusina, more specimens need to be examined and molecular biology techniques to be used in the future studies.

Due to the original literature not recording host plants of these planthoppers, they are not known. In our study, we found that a few specimens of Hauptenia (H. fellea, H. magnifica, and H. tripartita) were collected on bamboo. In addition, some specimens of H. glutinosa and H. jacula were collected by light traps, and we speculate that some species of the genus Hauptenia have positive phototropism.

Based on the diverse natural environment in China, we expect that further collecting will increase the number of new records or species, and suggest that specimens already collected and stored in collections should be reanalyzed.
