Two new species of Psychodidae (subfamilies Trichomyiinae and Psychodinae) from Germany associated with decaying wood

Abstract

Two new species of Psychodidae, Trichomyia stephani nov. spec. (subfamily Trichomyiinae) and Telmatoscopus thuringicus nov. spec. (subfamily Psychodinae) collected in Germany are described and figured. The larvae, like those of their close relatives are most probably bound to decaying wood. Cutting down in particular old trees finally axes habitats of many endangered red data list species.

What’s Inside the Hole? A Review of European Dendrolimnetic Moth Flies (Diptera: Psychodidae: Psychodinae)

“…), sycamore (Platanus sp.) [13,22,25,38] Telmatoscopus thuringicus Beran, Doczkal, Pfister & Wagner, 2010 Not specified (assumption of development) [5] Telmatoscopus laurencei Lime tree (Tilia sp.) [39] 3.1.…”

“…More than 30 tenacula; tenacula not restricted to the apical portion of hypopods, scattered in all the hypopods length (as in [5] (Figure 10)) . .…”

“…Dendrotelmata are commonly found in old trees, dead or alive, and are a considered crucial component of ecosystems, especially with the modern forestry management where the number of mature and over-mature trees (commonly referred as old trees) has decreased [5]. The main sources of nutrients flowing in the tree holes consist of leaf litter and arthropod cadavers, while the quality and composition of these nutrients vary across species and habitats [6,7].…”

“…There are six subfamilies recognized worldwide, namely Bruchomyiinae, Horaiellinae, Phlebotominae, Psychodinae, Sycoracinae, and Trichomyiinae; all of them except Horaiellinae are present in Europe [14,15]. Species in the subfamily Trichomyiinae develop inside tree holes or rotting wood and their larvae are considered xylophagous (from Greek "xylon", meaning wood, and "faguein", meaning eating) [5]. Species of Bruchomyiinae and Phlebotominae have been reported developing on the ground and leaf litter feeding on decaying organic matter [15].…”

The first trichomyiine from Burmese Cretaceous amber (Diptera, Psychodidae, Trichomyiinae)

“…They are found exclusively in decaying wood or tree holes filled partly with rain water (Beran et al, 2010). This cosmopolitan group is represented in extant fauna by about 85 species, all included in Trichomyia Haliday, 1839 (Satchell, 1956;Duckhouse, 1965Duckhouse, , 1978Duckhouse, , 1980Bravo, 1999Bravo, , 2001 even if this genus encloses a broad range of body structures (genitalia, etc.)…”
