Updating the knowledge of assassin bug cockroaches (Blattodea: Blaberidae: Paranauphoeta Brunner von Wattenwyl): Species from China and taxonomic changes

The investigation into the cockroach genus Paranauphoeta Brunner von Wattenwyl is insufficient, and there is a lack of taxonomic documentation of this genus from China. Recently, the authors obtained some newly collected specimens which facilitated this study. In this paper the generalized morphology of Paranauphoeta is interpreted in detail, particularly for the male phallic complex, which is illustrated as a whole rather than in pieces. The taxonomy of Paranauphoeta species from China is revised. One out of four species recorded from China, P. indica Saussure & Zehntner, is removed; instead, P. kirby nom. nov. is recorded from China. Together with three new species described in this paper, namely, P. anulata sp. nov. , P. brachyptera sp. nov. and P. lineola sp. nov. , a total of seven Paranauphoeta species are now known to occur in China, whose habitus photos are provided. The new species confirm that this genus is wing‐polymorphic. Male structures, if available, are illustrated. Female structures and oothecae, of which knowledge is limited in this genus and also in cockroach taxonomy, are illustrated or documented, respectively. A key to and a distribution map of the Paranauphoeta species from China are provided. In addition, P. atra Shelford nom. rev. , P. sinica Bey‐Bienko stat. nov. and P. vietnamensis Anisyutkin stat. nov. are regarded as valid separate species.     

The Madagascan click-beetle genus Crepicardus (Elateridae) and its relationship to the Pyrophorinae

The genus Crepicardus is endemic to Madagascar. Ten species are here recognized and redescribed; a key for their identification is given. The genus falls into three distinct species groups and one unassigned species: the klugii-group (klugii Castelnau, madagscariensis Fleutiaux, cribricollis Fleutiaux), the candezei-group (candezei Fairmaire stat.rev ., raffrayi Fairmaire, niger Candèze, puncticollis Fleutiaux), the trisulcatus-group (trisulcatus Candèze, mocquerysi Fleutiaux) and fleutiauxi Girard. Crepicardus costicollis (Castelnau) is again placed as a junior synonym of C.klugii (Castelnau) and candezei Fairmaire restored to specific status. Lectotypes are designated for klugii Castelnau, costicollis Castelnau, candezei Fairmaire, raffrayi Fairmaire, niger Candèze and mocquerysi Fleutiaux. On the basis of adult characters Crepicardus is here assigned to the Pyrophorinae sensu Stibick (1979) and its systematic position is discussed in relation to the widespread Pyrophorinae.     

Evolution and phylogenetic relationships within Porinaceae (Ostropomycetidae), focusing on foliicolous species

A phylogeny of the lichen family Porinaceae using mitochondrial SSU rDNA sequences is presented, with special focus on foliicolous taxa. Fifty specimens of 28 mostly tropical species, representing eight species groups of Porina as well as the genus Trichothelium, were analysed together with species of other members of Ostropomycetidae, and using Agyriaceae as outgroup. We performed the phylogenetic analyses with a Bayesian approach and under the criterion of maximum parsimony. Four main clades can be distinguished: the P. nitidula-group s. lat. (including Trichothelium, P. papillifera and P. rubescens), the Porina epiphylla-group s. lat. (including the P. radiata-, the P. nucula-, the P. imitatrix- and the P. epiphylla-group s. str.) and two clades of the P. rufula-group. The genus Porina as understood by all recent concepts is paraphyletic, and Trichothelium is nested within the Porina nitidula-group. The non-setose P. repanda forms a monophyletic clade with Trichothelium. The tree does not support a monophyletic origin of substrate preferences or photobiont selection. Species-specific associations with morphologically different trentepohlioid photobionts mapped on the tree suggest that closely related mycobiont species switch between different types of algae.

Ant assemblages in the taiga biome: testing the role of territorial wood ants

Summary Ants were collected with sets of pitfall traps in four coniferous-forest habitats in southern Finland. A three-level competition hierarchy concept was used to generate predictions on ant community structure. The levels of the hierarchy, and the respective predictions, from top to bottom were: (1) The dominant territorial wood ants (Formica rufa-group species), expected to exclude each other. (2) The other aggressive species, likely to be excluded by the F. rufa-group. (3) The submissive species, non-aggressive and defending only their nest, and thus likely to coexist with the dominants but in reduced numbers. As expected, the species of the F. rufa-group excluded each other, and the species number of the other aggressive ants was significantly cut down in the presence of the F. rufa-group. The aggressive species F. sanguinea and Camponotus herculeanus showed complementary occurrences with the F. rufa-group, and Lasius niger reduced occurrences. The number of the submissive species was not significantly affected by the F. rufa-group. However, pairwise correlation coefficients were significantly more often negative than positive between presence of the F. rufa-group and average proportion of pitfalls per set with a submissive species, each analyzed in turn. The result indicates that the F. rufa-group also reduced the colony densities of the submissive species. We conclude that in the taiga biome territorial wood ants are, after adjusting for physical vicissitudes of the environment, the major structuring force of ant species assemblages.     

Succession in zooplankton and hydrophytes of a seasonal water on the west coast of South Africa

Paramesochra mielkei sp.n. is described and figured from the interstices of subtidal sandy sediments off the SW Dutch coast. Kunz' (1981) phylogenetic scheme of the Paramesochridae Lang, 1948 is re-examined and it is suggested that the family comprises two phyletic lines which originated early in paramesochrid evolution. Translation into Linnean hierarchies implies the establishment of two new sub-families. Within the primitive Diarthrodellinae subfam. n., Tisbisoma Bozic, 1964 is ancestral to Diarthrodella Klie, 1949 s.l. and Rossopsyllus Soyer, 1975. Remanea Klie, 1929 is transferred to the Paramesochrinae subfam. n. which comprises the genera of both the Scottopsyllus- and the Paramesochra-group. The aberrant genus Caligopsyllus Kunz, 1975, standing close to Apodopsyllus, is removed from the Paramesochra-group. P. brevifurca Galhano, 1970 is splitted into two subspecies and replaced in the genus Paramesochra. An attempt is made to assess the phyletic interrelationships of the Paramesochra-species and the resulting cladogram splits the genus into four species-groups. P. mielkei sp.n. is referred to the dubia-group and seems to be closely related to P. borealis Geddes, 1981. Finally, an amended diagnosis and a revised key to the species of the genus Paramesochra are presented.     

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.     

Middle Jurassic fossils of the genus Sharasargus from Inner Mongolia, China (Diptera: Archisargidae)

To date, only two species of the genus Sharasargus are known. These Upper Jurassic species were found in Mongolia and Kazakhstan, respectively. We herein describe two new species from the Middle Jurassic, which were found in Inner Mongolia, China. They are the oldest known fossils of this genus. A key to Sharasargus species is given.     

Some remarks on the taxonomic status of Paraschizopera Wells, 1981 (Copepods: Harpacticoida)

The monotypic genus Paraschizopera Wells, 1981 (ex Diosaccidae) is transferred to the Tetragonicipitidae on the basis of segmentation of antennary exopod and P2-P4 endopods, setation of P1 and overall similarity in mouthpart structure. Paraschizopera is the most primitive genus of the family and closely related to Diagoniceps Willey, 1930 which is redefined to encompass only the laevis-group. The menaiensis-group is allocated to Paraschizopera which includes now P. beckeri Wells (type-species), P. menaiensis (Geddes) and P. trifida (Yeatman). The new name D. brevicauda is proposed for Diagoniceps sp. sensu Bodin (1979). Keys are provided to the species of Paraschizopera and Diagoniceps, and to the genera of the Tetragonicipitidae.
