The status ofPachygrontha solieri(Montrouzier) with the description of a new species from the New Guinea area (Hemiptera: Lygaeidae)

The status of the genus Neorthostigma Belokobylskij, 1998 is re-established as a result of additional morphological studies. A new species, N. braetisp. nov., from Papua New Guinea is described and illustrated. Aspilota brachyclypeataFischer 1978 is transferred to Neorthostigma, hence N. brachyclypeata (Fischer, 1978), comb. nov. A new synonym is suggested, Aspilota macrops Stelfox & Graham, 1951 = Neorthostigma eoum Belokobylskij, 1998, syn. nov.; A. macrops is transferred to Neorthostigma. This genus is additionally recorded in the Western Palaearctic (Norway) and Australasian (Papua New Guinea) regions for the first time. A key for the determination of the three known species of Neorthostigma is provided.

A New Species

We describe a new species of Cyrtodactylus from Karkar Island, an active volcano off the northern coast of New Guinea. It is a member of the C. sermowaiensis species group, which is defined by the absence of enlarged precloacal and femoral scales and the absence of precloacal/femoral pores in males. This species group includes two other species, one of which is widespread along the northern mountain ranges of New Guinea, and the other of which is restricted to Manus Island. The new species differs from each of these in its larger size; more-tuberculate dorsum; wide, even bands across the dorsum; and uniformly brown crown of the head. Distributional data suggest that the C. sermowaiensis species group originated on the former islands of the South Caroline Arc, although only C. sermowaiensis currently occupies terranes derived from that arc. The other two species are now restricted to volcanic islands that originated independent of that arc, but the current restriction of our new species to Karkar Island seems likely to be a relictual distribution of a formerly wider range. The status of Karkar as an active volcano, and the explosive sterilization or virtual disappearance of other islands in the Bismarck Volcanic Arc, suggest that the new species could be at threat of immediate extinction should a similar explosive eruption occur on Karkar.

A New Species

Morphological studies of Lechenaultia filiformis R.Br. have determined that more than one taxon is presently included under that name. We here recognise the suite of disjunct populations from north-east Queensland, north-east Northern Territory, New Guinea and the Moluccas as a new species, Lechenaultia peregrina R.W.Jobson & R.L.Barrett. This is the third tropical species of Lechenaultia currently recognised, however further studies are required to assess the status of about five additional entities in the Northern Territory and Western Australia currently included in L. filiformis s.l. Seed article morphology is critical for species delimitation in tropical Lechenaultia, but seed articles are often absent from collections, or only immature, as they fall quickly once ripe.
