First record of phoresy of Dendrochernes cyrneus (L. Koch, 1873) (Pseudoscorpiones, Chernetidae) on Cerambyx cerdo Linnaeus, 1758 (Coleoptera, Cerambycidae) and their potential value as bioindicators

Abstract

First record of phoresy of Dendrochernes cyrneus (L. Koch, 1873) (Pseudoscorpiones, Chernetidae) on Cerambyx cerdo Linnaeus, 1758 (Coleoptera, Cerambycidae) and their potential value as bioindicators.-The first evidence of phoresy of Dendrochernes cyrneus (L. Koch, 1873) on Cerambyx cerdo Linnaeus, 1758 is documented. A critical review of all known literature reports of phoresy involving D. cyrneus is also presented. Two of these reports relate to the same observation and are the result of the systematic turmoil within the family Cerambycidae. Both species are treated as primeval forest relics and their isolated populations live in the scattered remains of the ancient forests that covered Europe in the past. We provide new information about the ecological relationships of D. cyrneus with saproxylic beetles, and discuss the ecological preferences of the two species and their role as indicators of the quality of the environment. ResumenEl primer registro de foresía de Dendrochernes cyrneus (L. Koch, 1873) (Pseudoscorpiones, Chernetidae) en Cerambyx cerdo Linnaeus, 1758 (Coleoptera, Cerambycidae) y su valor potencial como bioindicadores.-Se documenta la primera prueba de foresía de Dendrochernes cyrneus (L. Koch, 1873) en Cerambyx cerdo Linnaeus, 1758. También se presenta una revisión crítica de todos los informes científicos publicados sobre la foresía relacionados con D. cyrneus. Dos de estos informes guardan relación con la misma observación y son el resultado de la confusión sistemática existente en la familia Cerambycidae. Ambas especies se tratan como vestigios del bosque primigenio y sus aisladas poblaciones viven en las zonas residuales dispersas de los bosques antiguos que cubrían Europa en el pasado. Aportamos nueva información sobre las relaciones ecológicas de D. cyrneus con escarabajos saproxílicos y analizamos las preferencias ecológicas de las dos especies y su función como indicadores de la calidad del ambiente.

The role of nature reserves in preserving saproxylic biodiversity: using longhorn beetles (Coleoptera: Cerambycidae) as bioindicators

“…Even if our results indicated a difference in the amount of deadwood between the managed and unmanaged sites, we could not detect an effect of the management type strictly on the species richness and abundance of Cerambycidae, perhaps due to the differences between the site pairs. However, the species that are the most valuable from a conservation point of view were found almost solely in nature reserves: C. cerdo-a primeval forest species included in all considered endangered species lists (Karpiński et al 2017)-in the MG1 site, S. scutellata (primeval forest species) in the M1 site, and A. gracilis (RLBSV) in the L1 and MG1 sites. The latter species was also recorded from a Natura 2000 site (L2).…”

Phoretic chernetid species newly recorded from Slovakia and Austria (Pseudoscorpiones: Chernetidae)

“…In Central Europe, phoretic associations were recorded mainly in chernetid species, such as P. scorpioides, D. panzeri, D. cyrneus, L. nodosus and Anthrenochernes stellae Lohmander, 1939(e.g. von Helversen 1966, Drogla & Lippold 2004, Ssymank & Muster 2010, Christophoryová et al 2017, Karpiński et al 2017. Phoresy of the genus Pselaphochernes Beier, 1932 was most recently documented from the Iberian Peninsula (e.g.…”

On the fauna of false scorpions (Arachnida: Pseudoscorpiones) of south-eastern Belarus

“…elongatus (Gyllenhal, 1827) under the bark of a standing dried-up pine near the village of Yakimovka,Rechitsa District,Gomel Region (N 52°23'27.1",E 30°36'24.7"). In this species, passive resettlement (phoresia) is observed on the beetles from the families Cerambycidae (Beier, 1929;Duchač, 1993;Huber, 2014;Jones, 1978;Karpiński et al, 2017;Kew, 1929;), Melandryidae (Vachon, 1954) and some others (Lohmander, 1939), as well as on the representatives of braconid wasps, family Braconidae (Kolomiets, 1980;Ressl, 2007), and ichneumon wasps, family Ichneumonidae (Legg, 2015). Adult false scorpions attach to the underside of the abdomen or to the legs of the host insect and follow it to the sites of xylophage settlement: Dryocoetes villosus (Fabricius, 1792) (Curculionidae: Scolytinae), Bitoma crenata (Fabricius, 1775) (Zopheridae) (Kew, 1929), and Ptilinus pectinicornis (Linnaeus, 1758) (Ptinidae) (Karpiński et al, 2017).…”
