Abstract: Two new species of oribatid mites of the family Carabodidae are described from litter in Thailand. Diplobodes parakanekoi sp. n. differs from Diplobodes kanekoi, D. africanus and D. aokii by fewer notogastral setae in the c-row, different number of notogastral tubercles, presence of a translamella, and the localization of dorsal notogastral setae. Machadocepheus pararachii sp. n. differs from Machadocepheus rachii by the positions of dorsal notogastral setae c1, da and la. The generic status of the related genera Diplobodes, Machadocepheus, Gibbicepheus, Gibbibodes, Kalloia, Neocarabodes, Sagittabodes and Zimbabweae is discussed.

Key words: carabodid mites, systematics, morphology, Oriental region, Oribatida.

Abstract: The oldest tenebrionid beetle Palaeobasanus neli gen. et sp. n. of the tribe Scaphidemini (subfamily Diaperinae) is described from the Paleocene of Menat (Thanetian) in France. The new extinct genus shows a distinct complex of characters of the tribe Scaphidemini, such as modified procoxal cavities, modified prosternal “cowling” and mesocoxal cavities partly closed by mesepimera. Palaeobasanus gen. n. differs from the extant Scaphidemini in the narrowly separated coxae, structure of prosternal process, which is moderately narrow at middle but strongly widened at apex and rounded (not truncate), abdominal intercoxal process, antennomeres 4–7 clearly covered by simple trichoid sensilla but without round sensory complexes as in recent Scaphidemini and Diaperini. All these mentioned characters seem to be symplesiomorphies within the tenebrionoid lineage, including oldest Mesozoic ‘tenebrionoid’ darkling beetles. It is thought that Palaeobasanus gen. n. could be a basal group within Scaphidemini, closely related to Diaperini, which probably existed at least in the border of the Mesozoic and Cenozoic.

Key words: diversification of Diaperini and Scaphidemini, new species and genus, fossil tenebrionids, Tenebrionidae.

Abstract: We review the phylogenetic and biogeographical connections of the Holarctic subgenus Polia, re-considering the diagnoses of the species groups based on the external morphology and the characterisation of the male and female genitalia, as well. We produced trees based on genital morphological characters. A preliminary CO1 consensus tree was also constructed which generally supports the morphologically outlined species groups. The plesiomorphic abdominal brush organ was observed to become lost in different species groups independently. The asymmetrisation of the tufts of bristles on the saccular extensions represents one of the most important traits of the genus. These are weakly differentiated, and the shape is nearly symmetrical in supposedly plesiomorphic character states. The most differentiated asymmetrical saccular processes were found in P. serratilinea and, parallel, also in the species of the Holarctic P. nebulosa group. Holarctic connections are present in most Arctic-Boreal species and certain sister species and/or species groups in temperate taxa (i.e. in the P. bombycina and the P. nebulosa species groups), with subsequent speciation in the Nearctic. It means that Trans-Beringian migrations should have occurred at least three times in the geographical history of Polia, from which the trans-migration of the basally split P. nebulosa group was the most ancient.

Key words: diagnosis, consensus tree, genital morphology, character status, sister species, biogeography, Polia, Noctuidae.

Abstract: To determine the relative role of climatic variables (temperature and precipitation) on land snail Xerolenta obvia populations, field surveys were conducted in Poland at two sites (SW and NE) with striking differences in climatic regime during two growing seasons. In a temperate climate of Central Europe X. obvia is an annual species with the majority of snails hatching in autumn. They overwinter as juveniles, continue their growth in spring and summer, and reproduce in the following autumn. Due to the comparatively milder climate, the SW population is more plastic, some individuals can live and reproduce longer. The two variants of the growth model are presented. We found that the length of growing season and temperature were additional factors determining differences in snails’ growth and population dynamics between the sites. The growth rate of X. obvia is negatively correlated with the initial size of their shells and varies among sites. These two geographically distant populations differ in terms of their shell size and morphology. The SW population is characterised by larger, dark banded shells compared to the NE one, which is dominated by snails with smaller, white shells. A pattern of decreasing body size in areas with shorter growing season may explain differences in the shell size of X. obvia. Larger shells in regions with warmer and drier environment perhaps constitute responses to selection by environmental factors.

Key words: growth rate, size structure of population, life cycle, terrestrial molluscs, Geomitridae, land snail, shell morphology.

Abstract: In the springs of 2015–2017, the population size and nest characteristics of the Eastern Rock Nuthatch (Sitta tephronota) were investigated. The study was conducted in a 400 hectare area of the mountainous region of southwestern Iran. In 2016, the population of the Eastern Rock Nuthatch was estimated at 33 pairs and its density was 8.25 breeding pairs per 100 ha of the study area. During the study, 45 nuthatch nests were investigated, of which 15 (33%) were found in cliffs and 28 (62%) were located in tree holes; 2% were built in house and bridge walls. The height of the nest was 214.3±112.3 cm above ground level. The mean of the horizontal and vertical depths of the nest chambers in trees was 17.8±3.7 and 12.6±3.2 cm respectively, and statistically differed from those in rocky nests (respectively 23.9±5.5 and 10.8±4.6 cm). However, chamber volumes did not statistically differ between these two nest type categories. The inner entrance areas of rocky nests were significantly smaller than those located in tree holes (respectively 11.1±2.3 and 15.3±5.5 cm2). Our findings suggest that differences in nest characteristics may be an adaptation of the Eastern Rock Nuthatch to predation.
