The molluscan genus Cominella (Gastropoda: Buccinidae) at the Three Kings Islands

Abstract

Three endemic taxa of Cominella Gray are recorded from the Three Kings Islands, New Zealand. Cominella (Josepha) regalis n.sp. and C. (Josepha) quoyana griseicalx n.ssp. occur sympatrically in relatively shallow water (to c.50m), whereas C. (Eucominia) mirabilis mirabilis Powell is known only from c.180m. The history of colonisation by these taxa is hypothesised and discussed.     

A systematic study of the pulchra species group of Archips occurring in Japan (Lepidoptera, Tortricidae)

This paper reviews the pulchra species group of Archips, describes a new species, Archips stellata, and redescribes A. pulchra (Butler) and A. abiephaga (Yasuda). Although long confused with each other, these three species are distinguishable by differences in the wing markings, abdominal dorsal pits, and genitalia. To position the pulchra group systematically within the genus Archips, earlier related studies are reviewed and the phylogenetic relevance and polarities of traits are discussed. The forewing pattern, consisting of transverse black and glossy gray fasciae, is presumed to be the only synapomorphy of this group; affinity between the pulchra group and other groups of Archips in some traits may reflect symplesiomorphy.
