AbstractLarvae of species representing 8 genera of the family Aturidae from North America are described, including members of the genera Ljania, Neobrachypoda, Estellacarus, and Aturus for the first time adequately. Larvae of species of Woolastookia, Brachypoda, Axonopsis, and Albia are also described to provide comparative data for these genera. A key to the genera of Aturidae, and preliminary diagnoses for the family, currently accepted subfamilies, and genera are provided based upon larval characters. Information on host associations is reviewed for each taxon. Observations on morphology and host associations of larvae provide the basis for a discussion of the phylogeny of these genera, and a review of the classification of the family.

AbstractLarvae of species representing 12 of the 13 genera of the superfamily Lebertioidea from North America are described, including members of the genera Bandakiopsis, Utaxatax, Estelloxus, and Testudacarus for the first time. Larvae of species of Sperchon, Sperchonopsis, Teutonia, Bandakia, Lebertia, Oxus, Frontipoda, and Torrenticola are also described to provide complete comparative data for the genera of the superfamily. A key to the families and genera of Lebertioidea, and preliminary diagnoses for the superfamily, families, and genera are provided based upon larval characters. Information on host associations is reviewed for each taxon. Observations on morphology and host associations of these larvae provide the basis for an original, though provisional, outline of phylogeny of Lebertioidea, and a review of the higher classification of the superfamily.

AbstractSince the advent of molecular taxonomy, numerous lichen-forming fungi with homoiomerous thalli initially classified in the family Collemataceae Zenker have been transferred to other families, highlighting the extent of morphological convergence within Lecanoromycetes O. E. Erikss. & Winka. While the higher level classification of these fungi might be clarified by such transfers, numerous specific and generic classifications remain to be addressed. We examined the relationships within the broadly circumscribed genus Arctomia Th. Fr., which has been the recipient of several transfers from Collemataceae. We demonstrated that Arctomia insignis (P. M. Jørg. & Tønsberg) Ertz does not belong to Arctomia s. str. but forms a strong monophyletic group with Gabura fascicularis (L.) P. M. Jørg. We also confirmed that Arctomia borbonica Magain & Sérus. and the closely related Arctomia insignis represent two species. We formally transferred A. insignis and A. borbonica to the genus Gabura Adans. and introduced two new combinations: Gabura insignis and Gabura borbonica. We reported Gabura insignis from Europe (Scotland and Ireland) for the first time. While material from Europe and North America is genetically almost identical, specimens from Madagascar, South Africa and Reunion Island belong to three distinct phylogenetic lineages, all of which are present in the latter area and may represent distinct species. In its current circumscription, the genus Gabura may contain up to six species, whereas Arctomia s. str. includes only two species (A. delicatula Th. Fr. and A. teretiuscula P. M. Jørg.). The Gabura insignis group is shown to have an unexpectedly large, subcosmopolitan distribution. With the extended sampling from Arctomiaceae Th. Fr., the placement of Steinera sorediata P. James & Henssen in the genus Steinera Zahlbr. is confirmed and the presence of a new Steinera species from Chile is highlighted.

AbstractNearctic mites of the family Anisitsiellidae are reviewed. A key and revised diagnoses are presented for the four genera, keys to species are provided for the first time, and distributional data are reviewed for each of the 13 known species. Three original species groups of Bandakia are proposed based on knowledge of nearctic species, but with the four exotic species tentatively placed. Adults of four new nearctic species, Bandakia borealis n. sp., Bandakia oregonensis n. sp., Bandakia fragilis n. sp., and Bandakiopsis fonticola n. gen., n. sp., are described. Reared larvae of Bandakia vietsi Cook and Bandakia borealis n. sp., the first known anisitsiellid larvae, also are described providing new insight on life history and phylogeny in the Anisitsiellidae.

A data matrix of 23 generic or subgeneric taxa versus 24 characters and a shorter matrix of 15 characters were analyzed by means of ordination, cluster analyses, parsimony, and compatibility methods (the last two of which are phylogenetic tree reconstruction methods) and the results were compared inter alia and with traditional methods. Various measures of fit for evaluating the parsimony methods were employed. There were few compatible characters in the data set, and much homoplasy, but most analyses separated a group based on Stylaria from the rest of the family, which could then be separated into four groups, recognized here for the first time as tribes (Naidini, Derini, Pristinini, and Chaetogastrini). There was less consistency of results within these groups. Modern methods produced results that do not conflict with traditional groupings. The Jaccard coefficient minimizes the significance of symplesiomorphy and complete linkage avoids chaining effects and corresponds to actual similarities, unlike single or average linkage methods, respectively. Ordination complements cluster analysis. The Wagner parsimony method was superior to the less flexible Camin–Sokal approach and produced better measure of fit statistics. All of the aforementioned methods contain areas susceptible to subjective decisions but, nevertheless, they lead to a complete disclosure of both the methods used and the assumptions made, and facilitate objective hypothesis testing rather than the presentation of conflicting phylogenies based on the different, undisclosed premises of manual approaches.

AbstractMorphological, life history, and distributional data are presented for North American species of the subgenus Stygomomonia (sensu stricto) Szalay, 1943. Adults of the seven previously recognized species are redescribed, and deutonymphs of five of these species are described for the first time. Two species, S. (s.s.) neomexicana Cook and S. (s.s.) occidentalis Cook are substantially revised on the basis of an examination of the types and extensive series of newly collected specimens. Three new species are described, S. (s.s.) californiensis on the basis of deutonymphs and adults, and S. (s.s.) imamurai and S. (s.s.) cooki on the basis of adults. A new diagnosis of the subgenus is proposed and discussed, the relationships of the various species are discussed, and a key to deutonymphs and adults of North American species is presented. New distributional data are presented for all species, and dispersal patterns from Pleistocene refugia are discussed.

The Ptiliidae of the Maritime Provinces of Canada is surveyed. Twenty-nine new provincial records from the Maritime Provinces of Canada are reported including the first records of the family from Prince Edward Island. Fourteen species are recorded for the first time for the Maritime Provinces as a whole. Acrotrichis josephi (Matthews) is recorded for the first time in eastern North America and Acrotrichis haldemani (LeConte) is recorded for the first time in Canada. The genus Pteryx is reported for the first time in Canada. At least 29 species of Ptiliidae are now known to occur in the region. The fauna is briefly discussed in terms of its overall composition, introduced species, and species associated with particular habitats. Saproxylic species found in mature forests are discussed and attention is drawn to their possible relationship to undisturbed forest conditions and the scarcity of old-growth habitats in the region.

Morphological data on the larvae of 37 species of freshwater mites (Hydrachnidia) known from springs in Luxembourg are reported. Larvae of Sperchon insignis (Walter, 1906), S. longissimus K.Viets, 1920, Lebertia holsatica K. Viets, 1920, Atractides fonticolus (K.Viets, 1920) and, with a question mark, A. pennatus (K.Viets, 1920) are described for the first time; re-descriptions are presented for Sperchon squamosus Kramer, 1879 and S. setiger Thor, 1898. Previous larval descriptions are listed and commented on for all species. Two species are recorded as new for the Luxembourgian fauna: Panisellus thienemanni (K.Viets, 1920) and Pseudofeltria scourfieldi Soar, 1904. A further taxon previously not recorded from springs in Luxembourg is described, probably Tiphys Koch, 1836 sp. An illustrated key is presented suitable for the determination of most parasitic water mite larvae attached to insect hosts from Luxembourgian springs.

The Way

The family Ægialitidæ, then known by but one species, was placed by Dr. LeConte (Classification of the Coleoptera of North America, p. xxxvi.) in association with those Heteromera having the anterior coxal cavities closed behind. This structure is also assigned to Ægialites in the detailed account of the insect on page 388 of the same work. Dr. Sharp, in his recent treatise on insects (Cambridge Natural History, Vol. VI., p. 265), speaks of the anterior coxæ as being “completely closed in,” while Dr. Geo. Horn, though dissecting a specimen for a study of the mouthparts, seems to have overlooked the coxal structure, or he would certainly have alluded to it in his notes on the genus (Trans. American Ento. Soc., XV., p. 27). In view of the statements in the books, I was surprised, a few months ago, by the receipt of a letter from the Rev. J. H. Keen, in which he asserted that the cavities of the anterior coxæ are open behind, as in indeed the case. Mr. Keen's observation is of great importance, in that it opens the way to a proper appreciation of the systematic position of the insect.

First Time

The comparactive morphology of the male and female postabdomen of the Australian Tachinidae was studied in a survey which included 152 species of representative genera from all subfamilies except Dufouriinae. The value of the structure of the postabdomen for the higher classification of the family was ascertained, and new information gained which has allowed a better understanding of the correct taxonomic position of some problem groups of tachinids. It was possible to recognise suites of characters for each sex to define each subfamily, but this was not possible at tribal or generic levels in most groups. The male terininalia are diagnostic at specific level. The survey also allowed the discovery of, or confirmed, the reproductive habit of the included genera and provided information on the first-instar larva of 52 species, many of which larvae are described below for the first time. Characters of puparia which may have taxonomic value are discussed and illustrated.

This paper updates the knowledge on the family Tachinidae (Diptera) in the Lithuanian fauna. As the result, 68 species are first records from the country and eight species are deleted from the previous list. Among species listed in this paper, 54 represent first records for the Baltic States and 16 are new for all of Eastern Europe. Parasitoid-host associations for 13 species of Tachinidae with 15 host taxa that comprise 17 couples are recorded for Lithuania for the first time. Among these, Meigenia uncinatata is a new parasitoid of the leaf beetle Gonioctena quinquepunctata (Chrysomelidae).
