Hypsotingis multiplantae sp. n.

( Figs 4 , 5 , 6 )

Material examined: 2M+1F, Canopy mission, Madang Province, Baiteta, 13/07/1995, Fog AR29-17; 1M+1F, 27/07/1995, Fog AR36-14; 1M, 12/07/1996, Fog AR64, O. Missa rec. IRScNB coll. One female of Fog 29-17 designed as holotype.

Description: Body covered by short setae, brown, with yellowish spots on hemelytra and pronotum, legs and antennae yellowish, except fourth segment dark brown, body beneath and head dark brown to black. Body length, 3.47±0.22; width (at posterior part of hemelytra), 1.05±0.13.

Head round, armed with five straight and slender spines directed forwards; occipital spines as long as horizontal length of eyes, shorter than median and frontal spines, frontal spines joining or crossing at apex, longer than horizontal length of eyes, median spine longest, slightly shorter than first and second antennal segment together; antennae long and slender, first and second segments stouter, third slender, fourth fusiform, antennal segment measurements, I, 0.12±0.01; II 0.12±0.02; III, 0.85±0.06; IV 0.34±0.03; bucculae biseriate, curved and joining in front; rostrum extending beyond meso-metasternal junction.

Pronotum gibbose, almost twice as long as wide; tricarinate, carinae raised and uniseriate, areolae larger anteriorly; median carinae with three additional small and round areolae before inflated part, inflated on anterior half of pronotum where gibbose, forming an elevated beanie-like hood, bent forwards, wide at base, narrowing at apex, concealing half of hood, nine areolae high, areolae polygonal and deeply incrustate, paranota reflexed and adpressed onto pronotum, not reaching lateral carinae, biseriate on anterior half, triseriate on posterior half, inner row perpendicular to outer row, areolae polygonal and as large as hood; sulcus straight and narrow, laminae uniseriate and straight; metathoracic sent gland opening large and auricular-like. Pronotum length, 1.90±0.13; width, 1.01±0.08.

Hemelytra straight, almost as wide as pronotum, sutural area covering at rest; costal area bent upward, irregularly biseriate, inner areolae smaller than outer areolae; subcostal area bent downward, as wide as costal area, triseriate, areolae round and smaller than on costal area; discoidal area longer than half length of hemelytra, five areolae wide at widest part, areolae same size and shape than on subcostal area, H+M and Cu veins raised and ridge-like; sutural area widening posteriorly, five areolae wide at widest part, areolae same size and shape than on outer margin of costal area. Hemelytra length, 2.33±0.13; discoidal area length, 1.34±0.11.

Comments: H. multiplantae differs from the two other known species of the genus, H. columna Drake 1960 and H. kaindi Guilbert 2006 , by the much narrower lateral carinae and the outer row of paranota with smaller areolae. It differs also by the irregularly biseriate costal area, while it is mostly three seriate on H. columna , and apically triseriate on H. kaindi .

The specimens were sampled by fogging on Chisocheton ceramicus (Meliaceae) , Celtis latifolia (Ulmaceae) , Dysoxylum patigravianum (Meliaceae) , Maniltoa sp. ( Fabaceae ) and Cryptocalia sp. ( Lauraceae ).

Etymology: the name of this species refers to the many plants on which the specimens were collected.
