Evaluation of Crenobia alpina and Crenobia montenigrina from Parang Mountains (Carpathians, Romania) according to the morphological and biological concepts of species

This paper assesses the taxonomic status - species or subspecies of the monopharyngeal and polypharyngeal Crenobia in Parang Mt. Romania. From the morphological point of view, the two forms belong to Crenobia alpina, respectively to Crenobia montenigrina. The analysis of the copulatory apparatus indicates a seasonal reproductive isolation (restriction from reproduction) of the two forms: the monopharyngeal alpina become able to mate during the warm season while the polypharyngeal montenigrina become able to mate during the cold season. Data on the reproductive biology and peculiar morphological data are also given. The study concludes that the monopharyngeal and the polypharyngeal Crenobia from Parang Mt. are good species according to both morphological and biological concepts.

Contribution to the genus Sympetrum Newman, 1833 (Odonata, Anisoptera) from extreme SW Romania

The paper presents new data on species composition and distribution of the genus Sympetrum in the extreme SW part of Romania. Two species, Sympetrum fonscolombii (Selys, 1840) and Sympetrum striolatum (Charpentier, 1840) are added to those of the literature - Sympetrum sanguineum (Muller, 1764) and Sympetrum meridionale (Selys, 1841) (Cirdei & Bulimar 1965). The sampled area was enlarged with new collecting sites. A brief description of species is given, especially the distinctive characters, including the hamular processes and the vulvar scale. The bifid aspect of the vulvar scale in S. meridionale indicates that the genus Sympetrum has a problem at least of species diagnosability.

Sympetrum sanguineum Newman, 1833 (Odonata, Anisoptera) - only one species with dimorphic females or two sibling species with identical males?

In this paper it is described a new Sympetrum species - Sympetrum bigeminus sp. nov. from Romania. The male of this new species is similar almost to identity with Sympetrum sanguineum from which differs only in the more conspicuous lateral thoracic sutures. The females are different from Sympetrum sanguineum by the vulvar scale, which is prominent (well visible in lateral view), incurved, with a deep concavity, and shortly bilobed, thus showing morphological characters of a different and distinct species.

Schmidtea sp., from the S-W Romania (Platyhelminthes, Tricladida, Dugesiidae)

The morphology and the anatomy of the copulatory apparatus in a Dugesiidae population from the SW Romania are presented. The copulatory apparatus is characterized by intermingled bursal canal musculature and two distinct penis bulbs with two large seminal vesicles. Based on these morphological characters, the population is assigned to the "lugubris-polychroa" group of species, now belonging to the genus Schmidtea (de Vries & Sluys 1991). The copulatory apparatus is also characterised by the presence of an atrial fold, characteristic of S. mediterranea. The assign of the morphotype here presented to the species level is delayed until integrative molecular analysis.
