Constant, Jerome, 2010, Extension of the genus Paruzelia (Hemiptera: Fulgoromorpha: Tropiduchidae) to Borneo with the discovery of a new species, Zootaxa 2716, pp. 64-68 : 65-67

Paruzelia rawette n.sp.

Figs 1 B, 1 E , 2 .

Etymology. Rawette is a Walloon word meaning “a little, a few” or an affective word to name something or someone “small and charming”. The name refers to the “small and charming” aspect of the new species. Walloon is the former primary language of a large part of the southern half of Belgium.

Material examined. holotype 3: [Coll I.R.Sc.N.B., Malaysia, Sabah (Borneo), Poring, 29.iii.1998, prim. Forest, Night fogging 1, Aporusa lagenocarpa , Euphorbiaceae (flowering) (ref Apla57), Leg. Andreas Floren, I.G.: 31.494] ( RBINS) coordinates: 5°59'N 116°14'E.

Other material examined. 1 ex: Malaysia, Sabah (Borneo), Sorinsim, 12.iii.1997, day fogging 1, Vitex pinnata (L.), Verbenaceae (ref Vipi282), B13, Leg. Andreas Floren, I.G.: 31.494 ( RBINS) coordinates: 6°29’N 116°44’E.

This specimen is in so poor condition that it is impossible to determine if it is male or female.

Description. LT: 3: 5.2 mm.

Head: ( Fig. 1 B ) vertex variegated brown, elongate, subrectangular, with obsolete median carina on basal 2/3; all margins carinate with sides strongly elevated above eye; frons elongate, broader basally, covered with erect hairs; anterior margin callused, side margins carinate; median carina on anterior 2/3; clypeus subtriangular; ocelli present; scape short, pedicel subcylindrical, about 1.5 times longer than broad at base; frons yellowish; sides yellowish with two red lines above eye and one before eye; ratio BV/LV = 0.84; BF/LF = 0.57.

Thorax: ( Fig. 1 B ) pronotum and mesonotum yellowish with irregular brown bands between carinae; pronotum with anterior margin rounded and posterior margin strongly emarginate; median and lateral discal carinae complete; sides strongly carinate between eye and tegula; mesonotum with median carina reaching basal transverse groove; lateral carinae curved, reaching median carina anteriorly; ratio BT/LP+LM = 1.1.

Tegmina: ( Figs 1 B, E ) twice longer than broad, apex largely rounded; hyaline with veins black-brown; transverse irregular brown band near base; broad transverse brown band with red and black markings as illustrated ( Fig. 1 E ) at nodal line; vein C strongly curved internally near nodal line; 11 apical cells between apex of clavus and node; apical cells elongate, cells 5, 7, and 8 subrectangular, cell 6 triangular; ratio LTg/BTg = 2.0.

Hind wings: slightly more than half as long as tegmina; hyaline with anal lobe and irregular band along nodal line, brown.

Legs: yellowish with basal half of femora III black; tibiae III with two lateral and five apical spines.

Abdomen: black dorsally; genital segment yellowish; ventrally yellowish with black-brown transverse band on segments; lateral membrane red.

Genitalia 3: pygofer higher than long, strongly narrowing dorsally; anal tube short and elevated in lateral view ( Fig. 1 G ); gonostyli with elongate baso-dorsal process projecting dorsad, apex spatulate and membranous, and strong latero-ventral emargination with external margin bisinuate and internal margin sinuate ( Figs 1 G, 1 H ); phallic structure simple, curved dorsad and with elongate ventral spinose process ( Fig. 1 G ).

Biology. One specimen was collected by canopy fogging a flowering Aporusa lagenocarpa A. Shaw (Euphorbiaceae) at night, the second on Vitex pinnata (L.) ( Verbenaceae ) at daytime. As the two specimens have been collected from different trees, host-plant associations remain impossible.
