Introduction

The tribe Issini Spinola, 1839 is the largest group in the family Issidae, including 134 genera with 712

species distributed worldwide (Gnezdilov 2013a; Chen et al. 2014; Bourgoin 2015). This tribe can be

diagnosed by the following characters: body ovate, head without proboscis on the frons and postclypeus,

frontoclypeal suture arched or almost straight, pronotum with large disc and narrow lateral lobes, hind

margin almost straight, tegmen usually not hemispherical, with distinct veins and claval suture, hind

wing well-developed and very often also rudimentary, bi- or trilobed, and hind tibia usually with two

lateral spines, sometimes without lateral spines.

Issini species from China were initially described by Walker (1851) from Hong Kong: Issus quadriguttatus

Walker, 1851 = Issus coleoptratus (Fabricius, 1781) (this species may be an error label in Hong Kong

according to Gnezdilov et al. 2004), Issus biplaga Walker, 1851 = Thabena biplaga (Walker, 1851).

This tribe in the Chinese fauna was studied thereafter by Schumacher (1915), Matsumura (1916, 1938),

European Journal of Taxonomy 181 : 1-25 ( 2016 )

Eskai (1931), Kato (1933), Jacobi (1944), Fennah (1956), Chou et al. (1985) and Chan & Yang (1994).

Recently, Gnezdilov (2009) and Gnezdilov & Hayashi (2013) proposed two junior synonymies ( Okissus

Matsumura, 1916 = Lollius Stal, 1866 and Paravindilis Yang, 1994 = Sarimodes Matsumura, 1916),

respectively; Gnezdilov & Wilson (2006) transferred Pterilia Stal, 1859 to the Caliscelidae and without

occurrences in China; Che et al. (2011, 2012), Meng & Wang (2012) and Chen et al. (2014) added four

genera and nine species to this tribe, and the latter reinstated the genus Gelastyrella Yang, 1994, mainly

according to unique characteristics of male and female genitalia.

Currently, 17 genera and 65 species of Issini were recorded in China, mostly in southern China.

However, the distribution of Issini remains poorly studied. In the present paper, a new genus and species

are added to this tribe: Orbita parallelodroma Meng & Wang, gen. et sp. nov. from Fujian Province in

South China. Anew species of Neokodaiana Yang, 1994 is also described and illustrated from the same

locality as O. parallelodroma gen. et sp. nov. A key to the genera of Issini from China and neighbouring

countries is provided below, it includes 18 genera recorded from China and six genera ( Vishnuloka

Distant, 1906; Jagannata Distant, 1906; Euxaldar Fennah, 1978; Darwallia Gnezdilov, 2010; Tapirissus

Gnezdilov, 2014; Dactylissus Gnezdilov & Bourgoin, 2014) from Vietnam, Faos and Myanmar. The

genus Neohemisphaerius Chen, Zhang & Chang, 2014 is also listed in this key for its tegmen has distinct

claval suture as the tribe Issini, although it was originally inculded in the tribe Hemisphaerini Melichar,

1906 (Chen et al. 2014).

Materials and methods

The external morphology was observed under a Feica MZ 125 microscope. All measurements are in

millimeters (mm). The terminology used for the external morphology follows Chan & Yang (1994),

the forewing venation pattern follows Bourgoin et al. (2014), “paradiscal fields of pronotum” follows

Anufriev & Emeljanov (1988) and “hypocostal plate of fore wing” follows Emeljanov (1971). The

terminology of the male genitalia follows Gnezdilov et al. (2014b), female genitalia mainly follows

Bourgoin (1993). The genital segments of the examined specimens were dissected and boiled in 10%

NaOH solution for about 2-3 minutes and subsequently transferred into glycerin. Photographs of the

specimens were made using a Feica M205A microscope with a Feica DFC Camera. Images were

produced using the software version FAS (Feica Application Suite) V3.7. Two females of Neokodaiana

minensis Meng & Qin sp. nov. are deposited in the Entomological Museum of Northwest Agriculture

and Forestry University (NWAFU), Yangling, China, and all other specimens were borrowed from the

Department of Entomology, China Agricultural University (CAU).

The measurements were mainly taken after Constant (2004) and the following abbreviations are used:

BA =

breadth of anal tube

BF =

breadth of the frons

BV =

breadth of vertex

BT =

breadth of thorax

BTg =

breadth of the tegmen

FA =

length of anal tube

FF =

length of the frons

FV =

length of vertex

FP =

length of pronotum

FM =

length of mesonotum

LTg =

length of the tegmen

TF =

total length

Type species

Orbitaparallelodroma Meng & Wang, gen. et sp. nov.

Diagnosis

Orbita gen. nov. can be easily distinguished from most genera in the tribe Issini by vertex quadrangular,

tegmen with ScP vein not reaching over middle, MP vein bifurcate near middle a little before the

furcation of CuA, hind wing well-developed trilobed and pattern of veins. Beyond these combination

features, the new genus is also similar to the genera Sinesarima Yang, 1994, Neosarima Yang, 1994,

Dactylissus Gnezdilov & Bourgoin, 2014 and Yangissus Chen, Zhang & Chang, 2014 . The new genus

can be differentiated from Sinesarima and Neosarima by the particular structure of lateral phallobasal

lobe and aedeagus no ventral hooks.

This new genus can be distingushed from Dactylissus by the following combination of characters

(features of Dactylissus in parentheses): 1) tegmen without hypocostal plate (tegmen with narrow

hypocostal plate); 2) vertex with weak median carina (vertex with no carina); 3) pygofer with hind

margin concave medially (pygofer with hind margin convex medially)

The new genus differs from Yangissus in the following combination of characters (features of Yangissus

in parentheses): 1) frons with distinct median carina reaching to below eyes, without sublateral carinae,

lateral margin auricularly extended below antennae (frons with feeble median carina almost reaching to

frontoclypeal suture, with feeble sublateral carinae, lateral margin obtusely extended below antennae);

2) hind wing without transverse veins between CuP and Pcu (hindwing with transverse veins between

CuP and Pcu); 3) pygofer with hind margin oblique and weakly convex at ventral half, caudo-dorsal

angle blunt not protudent (pygofer with hind margin slightly convex medially, caudo-dorsal angle

triangularly protrudent); 4) lateral lobe of phallobase becoming into processes at basal one third (lateral

lobe bearing processes near apex).

combination of characters (features of N. chihpenensis in parentheses): 1) anal tube with large triangular

projection near apex in lateral view (anal tube with the lateral projection small near apex); 2) lateral

phallobasal lobes with the middle triangular lobe-like processes long, anterior margin not dentate

Discussion

O. parallelodroma gen. et sp. nov. from southern China has two glossy rounded orbs on the frons,

which are also present in Chlamydopteryx mammoides Gnezdilov & Fletcher, 2010 from Queensland,

Australia (Gnezdilov & Fletcher 2010) and in Redarator bimaculatus Distant, 1916 from South India

(Distant 1916). The presence of this special feature in these three species from different geographical

locations indicates a parallel evolution. The presence of two orbs might reveal a function similar to

that suggested by Constant (2005: 62) for the smooth prominences on frons of Gelastopsis insignis

Kirkaldy (Hemiptera: Fulgoromorpha: Eurybrachidae) as being mimicry of the large frontal eyes of

salticid spiders. Many of these spiders are of similar size to these insects and move with short jumps.
