Chen, Xiang-Sheng & He, Ting-Ting, 2009, Two new species of Catonidia Uhler (Hemiptera: Fulgoromorpha: Achilidae) from southwestern China, with the first description of the male of Catonidia wuyishanana Wang & Huang, Zootaxa 2197, pp. 43-52 : 48-50

Catonidia daozhenensis Chen & He , sp. nov.

( Figs 21–30 , 37–39 )

Description. Body length (from apex of vertex to tip of forewing): 3 7.55–8.10 mm, ♀ 8.10–8.40 mm; forewing length 3 6.60–7.00 mm, ♀ 7.15–7.25 mm.

Coloration. General colour pale yellowish brown to pale brown ( Figs 37–39 ). Vertex, frons pale brown, clypeus pale yellowish brown. Rostrum pale brown. Genae brown. Eyes blackish brown, ocelli reddish brown. Antennae pale brown. Pronotum yellowish brown, areas behind eyes brown to fuscous. Mesonotum yellowish brown. Forewing milk-white with several small brown markings, apex brown. Hindwing nearly hyaline, venations pale brown. Legs brown. Abdomen yellowish brown to brown.

Head and thorax. Head including eyes narrower than pronotum (0.62:1). Vertex wider than long in middle line (2.52:1). Frons longer in middle line than widest part (2.00:1), width at base narrower than width at apex (0.84:1). Pronotum longer in middle line than vertex (1.39:1). Mesonotum longer in middle line than pronotum (5.16:1), and longer than pronotum and vertex together (3.00:1). Forewing longer than widest part (2.05:1). Spinal formula of hind leg 7–8–8.

Male genitalia. Anal segment longer than widest part (1.78:1) in dorsal view, apical margin broadly rounded ( Fig. 25 ). Pygofer in profile dorsal margin distinctly shorter than ventral margin, with dorsal third of posterior margin strongly angulated caudad, ventral third with a small lobe ( Fig. 26 ), in ventral view medioventral process broad at base, lateral margins slightly converging apically, apex protruded angularly ( Fig. 28 ). Genital style longer than width (2.13:1), apical margin broadly rounded, a stout, twisty process raising from apical third of dorsal margin, inner side of base with a short finger-like process ( Fig. 29 ). Phallobase tubular, in lateral view relatively narrow at base, dorsal lobe vestigial, lateral lobes converse beaked, broad at middle way, then narrowing apically, curving upward, acute at apex; ventral lobe slender, narrowing apically, acute at apex, with base strongly constricted, stalk-like ( Fig. 30 ). Genital lamina sclerotized, in lateral view beanpod shaped. Phallobasal conjunctival processes lateral view subparallel-sided, rounded at apex, each with an ear-like lobe laterally near apex ( Fig. 30 ).

Type material. Holotype: 1 3, Xiannvdong, Dashahe Natural Reserve, Daozhen County, Guizhou Province, 600–700m, 25–27 May 2004, X.-S. Chen; paratypes: 3 3, 1 ♀, same data as holotype; 1 3, Dashahe Natural Reserve, Daozhen County, Guizhou Province, 1500m, 29–31 May 2004, X.-S. Chen; 2 3, 1♀, Linjiang, Xishui National Natural Reserve (28°19´N, 106°12´E), Guizhou Province, 1 June 2000, X.-S. Chen ( IEGU).

Etymology. This species name is derived from the name of the holotype locality, Daozhen County, Guizhou Province.

Host plant. Unknown.

Distribution. China (Guizhou Province) ( Fig. 40 ).

Remarks. This new species resembles C. tibetensis in the shape of the frons, vertex and pronotum but differs from the latter in: vertex and pronotum pale brown to yellowish brown (castaneous and brown in the latter); forewing milk-white with several small brown markings (in the latter, forewing brown, with several small gray markings, costal margin with a large, and several small, fuscous markings on apical third); mesonotum three times as long as vertex and pronotum together (two times in the latter). This species also resembles C. guadunensis in the shape of the frons, vertex and mesonotum but differs from the latter in: anterior margin of pronotum produced angularly (in the latter, anterior margin of pronotum truncate); forewing with several brown to fuscous markings (forewing without any marking in the latter).
