Revision of the genus Menippus Clark in Australia (Coleoptera: Chrysomelidae: Galerucinae)

Abstract  The genus Menippus is revised for Australia, with six species, three of which are new: M. cynicus Clark, M. darcyi sp. nov. , M. ewani sp. nov. , M. fugitivus (Lea), M. sufi sp. nov. and M. yulensis (Jacoby) comb. nov. (from Diorhabda Weise). Menippus yulensis was described from New Guinea. This species and M. darcyi were formerly confused in Australia with M. fugitivus , which is now considered endemic to Lord Howe Island. The species formerly considered M. fugitivus and protected under the Threatened Species Conservation Act, New South Wales, is now named M. darcyi . A key is provided for the Australian species of Menippus and a lectotype designated for M. yulensis . The composition of Menippus is discussed and three non-Australian species are transferred to this genus: M. inconspicua (Jacoby) comb. nov. (from Diorhabda Weise); M. laterimaculata (Jacoby) comb. nov. ; and M. marginipennis (Jacoby) comb. nov. (from Galerucella Crotch). A revised checklist of Menippus species is given. The recorded foodplants of Menippus are species of Celtis (Ulmaceae).

Morphometric and molecular analysis of the Encarsia inaron species-group (Hymenoptera: Aphelinidae), parasitoids of whiteflies (Hemiptera: Aleyrodidae)

Several series of host-reared specimens of an Encarsia species, initially thought to be the cosmopolitan Encarsia inaron (Walker), were collected in the Azores Islands (Portugal). Subsequent morphometric analysis supported the presence of two species: E. inaron and a new species, described herein as Encarsia estrellae Manzari & Polaszek sp. n. Encarsia estrellae was reared from Aleyrodes singularis Danzig, A. ?singularis, and Bemisia sp. afer-group on several host plants. In addition, the D2 region of the 28S rDNA gene was sequenced in eight individuals belonging to these species, as well as single representatives of two closely related and one distantly related species. Phylogenetic analysis of these DNA sequences, together with 23 additional Encarsia sequences retrieved from the European Molecular Biology Laboratory (EMBL) and GenBank databases, further supported the specific status of E. estrellae, and the placement of E. dichroa (Mercet) in the E. inaron species-group. Additionally, E. inaron is redescribed and some taxonomic problems in the E. inaron species-group are discussed.

Taxonomic contribution to the Aleiodes melanopterus (Erichson) species-group (Hymenoptera, Braconidae, Rogadinae) from Brazil

The Aleiodes melanopterus (Erichson, 1848) species-group includes 21 species, of which seven are known from the Neotropical region: Aleiodes flavistigma Shaw, 1993, Aleiodes lucidus (Szépligeti, 1906), Aleiodes melanopterus, Aleiodes mexicanus Cresson, 1869, Aleiodes politiceps (Gahan, 1917), and the new species Aleiodes shaworumsp. n. and Aleiodes vassunungasp. n. Distribution ranges of Aleiodes melanopterus, Aleoides flavistigma and Aleiodes lucidus are extended and the female of Aleiodes lucidus is described. A key to the Neotropical species of this species-group is presented.     

Characterization of Alternaria isolates from the infectoria species-group and a new taxon from Arrhenatherum,Pseudoalternaria arrhenatheria sp. nov.

The infectoria species-group within the genus Alternaria was originally conceived by Simmons in 1993 and was based upon common morphological characteristics that included the development of conidial chains with primary, secondary, and tertiary branching resulting in substantial three-dimensional complexity. These characters can overlap to varying degrees with numerous taxa in another Alternaria group, the alternata species-group, making species-group differentiation difficult. However, members of the infectoria species-group are also distinguished from other small-spored Alternaria species based upon colony characteristics that typically include white or nearly white floccose colonies on DRYES medium and clumps of sporulation islands on low sugar media such as V8 agar, PCA, and weak PDA. In addition, the infectoria species-group contains representatives that are known to produce teleomorphs (Lewia), whereas the members of the alternata species-group and other Alternaria species-groups are strictly asexual. In this study, an assemblage of isolates recovered from varied hosts from the west coast of the United States were examined based upon morphological characters and compared to previously described members of the infectoria species-group. These isolates and members of the infectoria species-group typically produce arachnoid vegetative hyphae with multiple primary conidiophores, whereas other small-spored Alternaria species produce primary conidiophores predominately directly from the agar surface. Additionally, molecular phylogenetic analyses resolved these isolates and members of the infectoria species-group as distinctly nested amongst other sexual taxa in Allewia (Embellisia anamorph) and Macrospora (Nimbya anamorph) and phylogenetically distant to asexual lineages of Alternaria. One taxon among these isolates was novel and clustered with the asexual A. rosae in a distinct clade basal to all other members of the infectoria species-group. A new genus is proposed, Pseudoalternaria gen. nov. and a new taxon is described, Pseudoalternaria arrhenatheria sp. nov.. Moreover, a second taxon is reclassified, Pseudoalternaria rosae comb. nov.
