REVISION OF COELIDIINAk i 9 i 



Distribution. Raja Ampat Islands. 



Specimen examined. 



Coelidia subapicalis Walker, holotype <$, Raja Ampat Is. (West Irian): 'Mysol' 

 [Misool] {Wallace) (BMNH, London). 



HARANTHUS gen. n. 



(Text-figs 510-514) 

 Type-species: Haranthus pendiadus sp. n. 



Medium size leafhopper. General colour ochraceous with ivory spots on elytra. 



Head distinctly narrower than pronotum; crown produced beyond anterior margin of eyes, 

 disk elevated, slightly carinate laterally; ocelli near anterior margin; eyes large; pronotum 

 very broad, scutellum large; elytra elongate, venation prominent, outer anteapical cell closed, 

 five apical cells present, appendix very well developed; clypeus elongate, tumescent in lateral 

 aspect with median longitudinal carina arising posteriorly and fading or weak at anterior half; 

 clypellus short, margins parallel. 



Male genitalia symmetrical; pygofer with single long process arising from caudoventral 

 margin, aedeagus bipendulate with a pair of long processes on ventral appendage; gonoduct 

 on ventral appendage; connective as in Tkarra with short stem; style as in Tharra but not 

 clawed apically; plate as in Tharra. 



Haranthus is a monotypic genus. The genus has characters in common with 

 Tharra and with a new genus (to be described in a later part of this revision) of 

 Thagriini, and therefore may represent a phylogenetic link between the Tharrini 

 and Thagriini. The genus is known only from New Guinea. 



Haranthus pendiculus sp. n. 



(Text-figs 510-514) 



Length: g 9-00 mm, $ unknown. 



General colour ochraceous with numerous ivory spots on elytra. Crown ochraceous; eyes 

 rufous; pronotum and scutellum deep ochraceous; elytra deep ochraceous with numerous, 

 irregular ivory spots in cells; clypeus and clypellus light ochre. 



Head considerably narrower than pronotum; crown long and broad, produced distally 

 beyond anterior margin of eyes, distal length about one-third entire median length, striate 

 radially, disk elevated above eyes, lateral margins slightly carinate and nearly parallel; ocelli 

 situated near anterior margin; eyes large, occupying over half entire dorsal area of head, 

 tumose laterally; pronotum long, median length greater than median length of crown, surface 

 finely knobbed; scutellum large, median length greater than median length of pronotum; 

 elytra elongate, veins prominent, venation typical of genus, appendix well developed; clypeus 

 elongate, tumescent, lateral margins nearly parallel, slightly excised near antennal fossa, with 

 median longitudinal carina arising posteriorly and becoming obscure anteriorly, surface finely 

 granulose, narrowly rugulose along anterior margin; clypellus short, slightly tumid anteriorly, 

 lateral margins parallel. 



Male pygofer in lateral aspect with long prominent process arising from caudoventral margin, 

 process with 2 short secondary processes, one subbasal and one subapical; aedeagus 

 bipendulate; dorsal appendage narrow, equidistant throughout, curved dorsally at apex; 

 ventral appendage with apex extending beyond apex of dorsal appendage, long, with two pairs 

 of slender processes, the basal pair short and the distal pair long, each pair arising from dorsal 

 margin; gonopore apical on ventral appendage; connective broadly Y-shaped with short stem;
