Cladistic and phenetic studies of genera of Afrotropical Cryptobiina (Coleoptera Staphylinidae Paederinae) I. Cladistic approach

The monophyly of Staphylinidae, Paederinae and Cryptobiina is discussed. Using a cladistic analysis based on 40 exoskeletal characters, a hypothesis on the phylogeny of genera of Afro-tropical Cryptobiina is proposed. The cladogram clearly shows that these beetles have evolved alone three main pathways. Pathway 1 relates to a single genus, Matropium, the representatives of which exhibit many characters in plesiomorphic state and inhabit soil organic horizons of the Afroalpine zone in Zaïre. With regard to pathways 2 and 3, the observation of certain morphological traits (e. g. the shape of metanotum, the design of mesocoxal cavities) leads to the assumption that genera have developed distinct predation strategies and/or locomotion modalities: on the one hand, three strictly forest dwelling genera (Cryptofagiella, Pachyryptum and Nitidicryptum) have specialized towards a modality of running down or stalking prey in the rain forest; on the other hand, the eight remaining genera would have gained the ability either to hunt by flight or to move quickly in connection with an increase of flight performances, head mobility and visual acuity. This latter evolutionary pattern appears to be particularly evident in highly evolved genera like Monocrypta, Afrophitodum and Opbitodum.     

Cladistic and phenetic estimates of relationship among genera of eupomphine blister beetles (Coleoptera: Meloidae)

Abstract. The Eupomphina includes seven distinctive genera of Meloidae from the arid and semiarid zones of North America. Cladistic and phenetic estimates of relationship among genera are analysed and discussed. Both adult and larval characters are used, and the relative contribution of each to the classification of the subtribe is examined. Generic keys to adults and first instar larvae are included.     

Cladistic and phenetic analyses of relationships among Fusarium spp. in Dongtan wetland by morphology and isozymes

Variations of 12 morphological characters and 78 isozymic bands among 78 isolates of five Fusarium spp. from Dongtan wetland were described and analysed with cladistic parsimony and phenetic UPGMA methods. Hierarchical cluster analysis of 12 morphological characters grouped 78 strains into five defined species with a high overlap between isolates. Hierarchical cluster analysis of isozyme patterns showed a higher degree of relationship among five Fusarium spp., in which Fusarium nivale, Fusarium semitectum and Fusarium oxysporum clustered as one group, and F. semitectum was closer to F. nivale than to F. oxysporum; Fusarium graminearum and Fusarium moniliforme formed one group and showed clearly distinct from the first group. Groups of individual isolates indicated by a plot of principal component analysis were consistent with these findings. The comparison of two different data sets revealed that isozyme patterns showed higher variations between species and among individual isolates than morphological characters. Parsimony analysis of morphological characters yielded unresolved cladograms. Parsimony analysis of isozymes as presence/absence characters revealed the same five species in general as the results indicated by phenetic analysis, differing in the relative position of species in subclusters.

C-banding patterns in chromosomes of Paederius rubrothoracicus carpathicola Scheerpetz 1957 (Coleoptera, Staphylinidae: Paederinae)

An analysis was made of the C-banded karyotype of Paederius rubrothoracicus carpathicola Scheerp. The result indicates that the chromosome number is 2n = 36 and n Male = 17 + Xyp. The examined karyotype shows a paracentromeric position of constitutive heterochromatin in all autosomes. The y chromosome is wholly euchromatic.

Further studies on the Pselaphodes complex of genera from China (Coleoptera,Staphylinidae, Pselaphinae)

New data on the Pselaphodes complex of genera (Pselaphitae: Tyrini) from China is presented. The generic limits of Labomimus Sharp and Pselaphodes Westwood are discussed and expanded. A revised key to the genera of the Pselaphodes complex is provided. New geographic evidence suggests that previously believed wide-spread species Pselaphodes tianmuensis Yin, Li & Zhao contains a number of related species, resulting in a division of the species to nine separate taxa. Fourteen new species belonging to three genera are diagnosed, described and illustrated: Dayao emeiensis Yin & Li, sp. n. (Sichuan), Labomimus fimbriatus Yin & Hlaváč, sp. n. (Yunnan), Labomimus jizuensis Yin & Hlaváč, sp. n. (Yunnan), Labomimus simplicipalpus Yin & Hlaváč, sp. n. (Sichuan), Pselaphodes anhuianus Yin & Li, sp. n.

Labomimus sichuanicus Hlaváč, Nomura & Zhou (Sichuan) is redescribed and illustrated based on a paratype and the material from the type locality. Two recently described species, Pselaphodes tibialis Yin & Li (Yunnan), and Pselaphodes venustus Yin & Li (Yunnan), are transferred to Labomimus (comb. n.) due to the presence of a median metaventral fovea. New locality data is provided for Pselaphodes aculeus Yin, Li & Zhao (Anhui, Fujian, Guangxi, Hainan, Yunnan), Pselaphodes maoershanus Yin & Li (Guangxi, Guizhou), Pselaphodes tianmuensis (Zhejiang, Anhui, Fujian, Jiangxi, Guangxi) and Pselaphodes pectinatus Yin, Li & Zhao (Hainan), with the aedeagus newly illustrated for the latter species.
