Tingis (Tropidocheila) waui sp. n. ( Fig. 6 )

Material examined: 1M, New Guinea, NE, Wau, 1200m, 11.XII.1965, J. & M. Sedlacek, light trap, BPBM. 1M, New Guinea, NE, Morobe prov., Wau, 1300m, 25.X–6.XI.1982, U.V. trap, W.C. Gagné, 1983.90, BPBM.

Description: Body clear brown, with dark brown spots on the middle of costal area and on the top of carinae; head, fourth antennal segments, hind tarsi, and body beneath dark brown. Body length, 2.83; width, 0.97.

Head short, sparsely pilose on top, armed with five spines; occipital spines long and stout; frontal and median spines short and stout; bucculae long, and narrow, biseriate, proximate in front; antennal segments measurements I, 0.13; II, 0.10; III, 0.68, IV, 0.30; rostral sulcus narrow and narrowly open posteriorly; rostrum extending a little beyond meso­metasternal suture.

Pronotum long, gibbose, tricarinate, carinae subparallel, raised, uniseriate, the areolae tiny; collar not raised, triseriate; paranota reflexed onto the pronotum, narrow, uniseriate, four to five small areolae near calli, posterior areolae much smaller.

Hemelytra narrow, as wide as pronotum; costal area partly uniseriate, with some extra areolae in a second row, but smaller and irregular; subcostal area slightly wider, bent downward, biseriate, the areolae as small as those of costal area; discoidal area more than half the length of the hemelytra, six to seven areolae wide at widest part, the areolae larger than subcostal and costal areas; sutural area large, ten areolae at widest part, areolae large.

Etymology: The name of this species refers to the type locality.

Comments: This species is similar to Tingis irregularis (Montrouzier) from New Caledonia, which has a similar but narrower biseriate costal area, whereas the collar is biseriate in T. waui and quadriseriate in T. irregularis ( Guilbert 1997) . The new species differs from T. toxopeusi Drake (1960) , the only other Tingis species occurring in New Guinea, which has a costal area which is not biseriate. This species is placed in the genus Tingis because the costal area is not strictly uniseriate, as in Eritingis Drake and Ruhoff (1962) . It is very similar to E. recens (Drake and Poor) , but differs from it by the costal area. In addition, all other characters link up with Eritings. A revision of this group is needed to clearly define the relationships between Tingis and Eritingis .
