Abstract Specific identification of oestrid larvae is usually problematic not only when using morphobiometric features, but also when applying molecular criteria, since very few molecular markers have been described for this group of flies. New molecular markers for oestrid are needed for more reliable species identification, diagnostic purposes, and epidemiological surveys; moreover, they can help in phylogenetic reconstruction. Here, we report the characterization of COI, 28S rDNA, ITS1, and ITS2 in Cephenemyia stimulator from roe deer and in Cephenemyia auribarbis and Pharyngomyia picta from red deer. The COI and 28S rDNA are very uniform in length, while the ITSs sequences are highly variable at both intraspecific and interspecific levels. The described ITSs sequences were longer than those described for other dipteran species by the presence of simple repeats and tandem repeat sequences. In C. auribarbis both ITS1 and ITS2 appeared as two variants, one short and the other long. In general, the analyzed markers present low intraspecific genetic variation and high interspecific variation. ITSs showed the greatest amount of intraspecific and interspecific variation. Phylogenetic analysis demonstrated that the characterized sequences differentiate the species and genera of Oestridae.

Abstract The Louisiana iris species Iris brevicaulis and I. fulva are morphologically and karyotypically distinct yet frequently hybridize in nature. A group of high-copy-number TY3/gypsy-like retrotransposons was characterized from these species and used to develop molecular markers that take advantage of the abundance and distribution of these elements in the large iris genome. The copy number of these IRRE elements (for iris retroelement), is ∼1 × 105, accounting for ∼6–10% of the ∼10,000-Mb haploid Louisiana iris genome. IRRE elements are transcriptionally active in I. brevicaulis and I. fulva and their F1 and backcross hybrids. The LTRs of the elements are more variable than the coding domains and can be used to define several distinct IRRE subfamilies. Transposon display or S-SAP markers specific to two of these subfamilies have been developed and are highly polymorphic among wild-collected individuals of each species. As IRRE elements are present in each of 11 iris species tested, the marker system has the potential to provide valuable comparative data on the dynamics of retrotransposition in large plant genomes.

Morphological And Molecular Characterization

Buzionema lutgardae n. sp. (Nematoda: Oxyuridomorpha: Thelastomatidae) is described from the cockroach Byrsotria sp. (Blattaria: Blaberidae), endemic to Cuba. Females of B. lutgardae n. sp. are shorter than those of B. validum Kloss, 1966 (1600–2150 µm vs. 3131–3378 µm), but the oesophagus is comparatively longer (b = 2.96–3.77 vs. 4.65–4.87). The lateral alae of the new species extend from ca. the midpoint of the cylindrical part of the procorpus to the level of the anus in contrast to the base of the basal bulb to the level of the anus in B. validum. The males of B. lutgardae n. sp. are shorter than those of B. validum (780–940 µm vs. 1177–1423 µm) and their lateral alae end at some distance before the cloaca instead the level of the cloaca in B. validum. The phylogeny of B. lutgardae n. sp. is inferred by the D2-D3 domains of the 28S rDNA. B. lutgardae n. sp. and B. validum form a monophyletic clade with strong nodal support, as sister-group of the genus Leidynema Schwenck in Travassos, 1929.
