Bu, Cui-Ping, Larivière, Marie-Claude & Liang, Ai-Ping, 2010, Parapiromis nom. nov., a new name for Piromis Fennah (Hemiptera: Fulgoromorpha: Ricaniidae), with descriptions of three new species, Zootaxa 2400, pp. 29-40 : 34-36

Parapiromis guadalcanalensis sp. nov.

( Figs. 16–24 , 43 )

Description. 3 (n=2), BL: 8.5 mm, FWL: 8 mm; Ƥ (n=1), BL: 9 mm, FWL: 8.5 mm

General colour brown. Vertex and frons pale brown. Clypeus brown, with a narrow pale brown stripe at middle. Rostrum pallid. Pronotum and mesonotum brown. Thorax pale brown ventrally, marked with fuscous. Legs pale brown; tarsi and tips of tibiae fuscous. Abdomen brown ventrally, with pale yellow transverse stripes; pygofer fuscous. Fore wing with brown precostal area and costal cell, hyaline, more or less fuliginous at anterior part of corium, many hyaline areoles near subapical line and apical angle, forming wide brown band near middle; apical margins with wider brown fascia; stigma greenish white, nearly opaque.

Head (including compound eyes) ( Figs. 16, 17 ) slightly narrower than pronotum. Vertex ( Fig. 16 ) wider at anterior margin than long in middle line (11.5:1). Frons ( Fig. 17 ) wider at widest part than long in middle line (1.3:1); disc tricarinate, sublateral carinae longer than central carina. Clypeus ( Fig. 17 ) triangular, without central carina.

Pronotum ( Fig. 16 ) wider at widest part than long in middle line (6.3:1), punctuated beside central carina. Mesonotum ( Fig. 16 ) large, longer than broad, with tricarinate on disc, lateral carinae weakly sinuately converging anteriorly and narrowly rounding to meet in middle line, anterolateral carinae almost straight, disuniting with lateral carinae at middle. Wing venation as in Figs 18–19 .

Male genitalia with pygofer ( Fig. 21 ) narrow and high, with dorsal posterior margin smoothly produced posteriorly in lateral view. Anal tube ( Fig. 20 ) moderately large, oval in dorsal view, longer than wide at middle (1.5:1). Genital styles ( Fig. 21 ) relatively large, broad in lateral aspect, with long apical process, in profile longer than wide at middle (2.7:1). Aedeagus ( Figs. 22–24 ) stout, nearly straight, mostly sclerotised, with 31 short spines and one membranous tubule ventrally in discal half: 20 short spines on lateral margins, and 11 short spines near middle, and two pairs of cephalad directed dorsal processes at apex, the inner pair spinose short, deeply crossed, the outer pair long, moderately sinuate, narrowly tubular and weakly sinuate in basal, membranous in the succeeding, and sclerotised and acuminate apically, nearly paralleled near base, crossed at end.

Material examined. Holotype 3, Solomon Islands Guadalcanal: Honiara, 0–200 m, xii.1972, N.L.H. Krauss ( BPBM). Paratypes. Solomon Islands: 13, Malaita: Dala, 50 m, 15–19.vi.1964, J. & M. Sedlacek, Malaise Trap ( BPBM); 1Ƥ, Guadalcanal: Honiara, 0–200m, xii.1980. N.L.H. Krauss ( AMNH).

Etymology. This species is named after its distribution in the Solomon Islands (Guadalcanal: Honiara).

Distribution. Solomon Islands.

Remarks. This species is similar to Parapiromis translucida (Montrouzier) in appearance but can be distinguished from the latter by its fore wing with a smaller fuscous spot near the apical angle and a wide brown interrupted band near the middle ( Fig. 18 ), its aedeagus with 31 short spines and one membranous tubule ventrally in discal half and deeply crossed inner processes ( Figs. 22–24 ).
