Ordo: Hemiptera
Familia: Dictyopharidae
Genus: Saigona
Name
Saigona baiseensis Zheng & Chen sp. nov. – Wikispecies link – ZooBank link – Pensoft Profile
Type locality
Tianlangping Baise, Guangxi Zhuang Autonomous Region, China.
Diagnosis
This species can be distinguished from other Saigona species by the combination of the following diagnostic characters: (1) pygofer large and broad in lateral view, posterior margin with a blunt dorsal process; (2) aedeagus with phallobasal conjunctival processes unequal in length; (3) phallobase narrow and long, curved dorsally, with 2 apical membranous dorsal apical lobes (Fig. 12), dorsal round and large; ventral lobes (Fig. 13) small and slender, with another small membranous lobe on it.
Description
Measurement. ♂, BL: 17.4–18.9 mm; HL: 1.5–1.6 mm; HW: 1.4–1.5 mm; FWL: 11.3–13.2 mm. ♀, BL: 18.9–20.2 mm; HL: 1.6–1.7 mm; HW: 1.4–1.5 mm; FWL: 13.2–14.6 mm.
Coloration. General color dark, marked with fuscous and ochraceous (Figs 2–5). Vertex brown with median carina very faint, lateral margins dark. Genae dark, yellow ventroposteriorly near antennae (Fig. 4). Eyes dark brown, lateral ocelli yellowish, antenna brown and areas surrounding ocellus and antenna beneath eye yellowish. Frons dark brown with yellowish speckles (Fig. 3). Postclypeus and anteclypeus pale brown. Pronotum dark with scattered white speckles; mesonotum dark, with broad median longitudinal yellowish stripe. Ventral thorax and fore femur dark, other areas yellow. Legs ochraceous except coxae which are dark. Forewing venation brown and pterostigma dark. Abdomen dark with scattered white speckles and median longitudinal yellowish stripe. Male genitalia black. Head and thorax. Head (Figs 2–5) longer than pronotum and mesonotum combined (1.45:1). Vertex (Fig. 3) with median carina very faint, only conspicuous at apex and base; lateral carinate margins sinuate. Frons (Fig. 3) with lateral carinae reaching to front of eyes. Pronotum (Figs 2, 3, 5) with median carina distinct, lateral carinae very faint. Mesonotum (Figs 1, 2) tricarinate on disc, lateral carinae curved towards median carinate at the front. Fore wings (Figs 2, 6) hyaline with ScP+R, MP and Cu branched apically, longer than widest part, with length to maximum width ratio of 3.0; stigma distinct, with 3 or 4 cells, veins with numerous fuscous setae. costal margin distinctly expanded into a narrow, sclerotized costal area, without transverse veins; ScP+R branched apically; MP bifurcating into MP1+2 and MP3+4 at basal 3/5 and beyond CuA; CuA forked near middle of forewing; 13 apical marginal cells between RP and CuA; Pcu and A1 fusing at apical 2/5 of clavus. Hindwings (Fig. 7) well developed, legs moderately elongate, fore femora flattened and dilated; hind tibiae with 5 or 6 lateral black-tipped spines and 8 apical black-tipped teeth, spinal formula 8/(10–12)/(10–12).
Male genitalia. Pygofer (Figs 8–10) large and broad in lateral view, posterior margin with a rounded lobe at level of venter of anal tube. Gonostyli (Figs 8, 9) relatively large and broad, apex sharply rounded, protruded posteriorly in lateral view on the outer surface of the gonostyli (Fig. 8). Aedeagus (Fig. 11) with phallobasal conjunctival processes unequal in length, left one obviously longer than right one; phallobase narrow and long, curved dorsally, with 2 apical membranous dorsal apical lobes (Fig. 12) dorsal round and large; ventral lobes (Fig. 13) small and slender, with another small membranous lobe on it. Segment X large in lateral view (Fig. 8), large, long, ovoid in dorsal view (Fig. 10), ratio of length to width at middle about 1.5. Female genitalia (Figs 14, 16) with gonocoxae VIII with GxP membranous and flattened (Fig. 16). Gonopophyses VIII with anterior connective lamina of gonapophyses (ACL) moderately sclerotized with 7 unevenly sized teeth in lateral view. (Fig. 16). Gonopophyses IX (Fig. 17) with posterior connective lamina of gonapophysis IX (PCL) triangular, symmetrical in ventral view, connected at base and separated from 1/3 base. Gonoplacs (Fig. 18) with 2 sclerotized lobes: gonoplacs (Gp), with 3 or 4 long spines at apex, and posterior lobe of the gonoplac (GpL) with membranous structure at top. Segment X in dorsal view relatively round and large, with ratio of length to width at middle about 0.8 (Fig. 15).
Type material
Holotype ♂, Tianlangping Baise, Guangxi Zhuang Autonomous Region, 24 Apr. 2012, Weicheng Yang. Paratypes, 8♂♂2♀♀, same to holotype, Weibin Zheng, Zaihua Yang, Jiankun Long.
Etymology
This new species is named for the type locality, Baise City, Guangxi, China.
Distribution
China (Guangxi).
Remarks
This species is similar to S. fulgoroides (Walker, 1858) (Liang and Song 2006[1]: figs 20, 23–25) but can be distinguished by the large, broad pygofer (in lateral view) with its posterior margin bearing a somewhat blunt process dorsally (vs sharp, dorsoposteriorly directed process near apex in S. fulgoroides); the aedeagus has a conjun
