The peculiar Asian ghost moth genus Bipectilus Chu & Wang: taxonomy and systematic position (Lepidoptera: Hepialidae s.str.)

Abstract Bipectilus Chu & Wang, 1985, from China, Nepal, Thailand and Vietnam is redescribed. Eight species are recognized in the genus; two were described previously ( Gorgopis unimacula Daniel and Bipectilus yunnanensis Chu & Wang) and six new species are named. A key to the males is provided and all species and their genitalia are described and illustrated. One new combination is established and one lectotype is designated. Observations on the cuticular anatomy of Bipectilus are presented. The monophyly of Bipectilus is supported by several autapomorphies but the genus also possesses many plesiomorphic traits including spurs on the hind tibia in some species. Bipectilus is placed in the Hepialidae s.str. and the autapomorphies of that taxon are summarized. It is concluded that Bipectilus represents an early lineage within the family, and possibly represents the sister-group of all other Hepialidae s.str. All Asian species originally placed in Gorgopis Hübner are removed from this endemic Afrotropical hepialid genus.     

A new subfamily, two new genera and three new species of Aclerdidae (Hemiptera: Coccoidea) from southern Africa, with a phylogenetic analysis of relationships

Abstract A new aclerdid genus, Lecanaclerda Hodgson & Millar, closely related to Aclerda but with fully developed legs and antennae, is introduced for a new new species, L. macropoda Hodgson & Millar, for which the male and female are described. In addition, genus Rhodesaclerda McConnell is revised and all known stages of existing species, R. combreticola McConnell and R. halli McConnell, are redescribed. The crawler, second-instar female, pupa and the adult male and female of a new species, R. insleyae Hodgson & Millar, from South Africa are also described. Another new genus, Kwazulaclerda Hodgson & Millar, close to Rhodesaclerda , is introduced and the crawler, second-instar female, second-instar male, pupa and adult male and female of the new species K. loranthi Hodgson & Millar from Kwazulu-Natal are described. A phylogenetic analysis based on adult macropterous male characters was undertaken to look at the relationships of these species with other Coccoidea. It is concluded that Lecanaclerda is closely related to Aclerda , Kwazulaclerda is closely related to Rhodesaclerda , Kwazulaclerda and Rhodesaclerda belong to Aclerdidae, and Aclerdidae should be split into two subfamilies, Rhodesaclerdinae Hodgson & Millar (to include Rhodesaclerda and Kwazulaclerda ) and Aclerdinae Cockerell (to include Aclerda , Lecanaclerda and Nipponaclerda ). These two subfamilies are diagnosed and a key is given for the separation of the genera now included in Aclerdidae. The relationships of Aclerdidae and Coccidae are discussed.     

STRUCTURE AND REPRODUCTION OF AMANSIA AND MELANAMANSIA GEN. NOV. (RHODOPHYTA,RHODOMELACEAE) ON THE SOUTHEASTERN AFRICAN COAST1

Four species of Amansia Lamouroux were initially found in Natal. More Complete studies on these species revealed a new genus, Melanamansia, Which is described on the basis of presence of two dorsal pseudopericentral cells in two new species from Natal (M. seagriefii sp. nov. & M. fimbrifolia sp. nov.) in addition to other structural characters and features of pigmentation and reproduction. Pseudopericentral cells are not present in the type species of Amansia, A. multifida Lamouroux. The other two species of Amansia occurring in Natal, A. glomerata C. Agardh & A. loriformis sp. nov., have characters similar to the type species. Comparison of species from other regions of the world has shown that eight additional species, previously assigned to Amansia, belong to the new genus.     

The pennatulacean genus Cavernularia Valenciennes (Octocorallia: Veretillidae)

Two new species of sea pens referable to the genus Cavernularia Valenciennes are described from Natal and Transkei, east coast of southern Africa, at depths of 24 and 190 to over 300 m. The two new species are distinguished from other members of the genus by unique combinations of features regarding the axis, colonial growth form, autozooid size, as well as the size, shape, and distribution of sclerites. A comparative review of the genus is included. The 13 presently recognized worldwide species are differentiated and a key for their separation, together with a table of comparative characters, is provided. Of these, ten (77%) are Indo-Pacific in distribution whilst the remainder (23%) are presumably restricted to the eastern Atlantic. Four species are presently recorded from southern Africa. The deepest known bathymetric stations for the genus are here recorded from northern Namibia at 274 m, and from northern Natal at 310/320 m. Relationships to members of the related genus Cavernulina Kükenthal & Broch are discussed.     

Aoruroides queenslandensis n. sp. (Oxyurida: Thelastomatoidea), a new nematode from Australian Panesthiinae (Blattodea: Blaberidae)

A new thelastomatid, Aoruroides queenslandensis, is described from two native Australian cockroaches, Panesthia tryoni tryoni Shaw and P. cribrata Saussure, from sub-tropical rainforest in south-eastern Queensland. Species of Aoruroides Travassos & Kloss, 1958 have previously been reported from cockroaches found in Brazil and the Philippines, but A. queenslandensis n. sp. is the first species of this genus found in Australia. The new species differs from the other members of Aoruroides principally in the position of the nerve-ring and egg morphology.     

A new species report of Caroperla Kohno, 1946 (Plecoptera: Perlidae) from China

A brief taxonomic synopsis of the genus Caroperla Kohno, 1946 is presented and its further generic delimitation is defined along with a new species, C. siveci sp. n. from the Wuyishan Mountain of Fujian, China. It represents the first report of the genus from China and the third species of the genus. The morphological comparison of the new species with the two other known species is given.
