Zhang, Yalin, Zhang, Xinmin & Dai, Wu, 2008, Three new species of the genus Krisna Kirkaldy (Hemiptera: Cicadellidae: Iassinae) from China, with a checklist of the genus, Zootaxa 1783, pp. 40-60 : 45-47

Krisna daiyunensis sp. nov.

( Figs 2 , 10 , 19 , 34–42 )

Ochraceous, anterior margin of head piceous. Forewing appendix without basal fuscous spot.

Head with crown short, anterior margin rounded between eyes, medially slightly longer than next to eyes, anterior margin slightly rimmed. Upper part of frontoclypeus depressed. Ocellus situated on front margin of crown next to corresponding eye, separated from eye by distance equal to ocellus diameter. Male eighth sternite with hind margin slightly concave.

Male genitalia with pygophore elongate, with many macrosetae posteriorly; ventral pygophore process in lateral view curved dorsally, shorter than length of pygophore, apical area with few longitudinal rugae. Style very long, apophysis long and narrow, curved dorsally at apex without thickening. Aedeagus broad at base, with short preatrium, distal 2/5 upturned, narrow with transverse rugae, in caudal aspect, midlength of shaft slightly narrow, widened near apical region; phallotreme apical on ventral surface.

Measurements: Male 10.7mm long, 2.8mm wide across eyes, 3.4mm wide across hind margin of pronotum.

Material examined: Holotype ɗ, Fujian Prov.: Daiyunshan, 30 July 1984, Wang Sizheng; paratype: 1 ɗ, data as for holotype ( NWAFU).

Distribution: China (Fujian).

Remarks: This species resembles K. nigromarginata Cai & He externally but can be distinguished from the latter by the male pygophore lacking a prominent projection on the ventral margin.

Etymology: The species name, an adjective, refers to Daiyun Mountain where type specimens of the new species were collected.
