Diagnosis

Trichosiopsis rejecta is a large species. It is characterized by the shiningly yellow legs with bright, mostly white hairs on the fore coxae. The palpi are very long and the gonostyles are elongate with a distinct, slightly obtuse dorso-apical angle. The dorsal margin of the gonostyli is not as straight as in Trichosiopsis scutellata, which has nearly rectangular gonostyli.

DNA Barcoding

The COI sequence is assigned to BIN BOLD:ACK0157 (average distance 0.22%, max. 0.82%, n=24, K2P: 7.95%).

Discussion

This species was originally described from the female sex only, so that the correctness of the present species concept cannot be absolutely certain. The lectotype was studied again (Fig 1), and its interpretation of Mohrig & Menzel (1997: 62-65, Fig. 11) is followed, even though the legs are a bit darker than in most other specimens. Otherwise the studied material agrees with the figures in the redescription by Mohrig & Menzel. The species is deemed to be identical to Leptosciarella pilosa sensu Edwards (1925[3]: 536, fig. 9), Frey (1948[4]: 74, fig. 17) and Tuomikoski (1960[5]: 22) [for more nomenclatural details see the discussion under Trichosiopsis pilosa]. All these authors point out the apparent variability and the species limits were never very clear cut. DNA barcoding showed up, that this species in the sense of Menzel & Mohrig (1997), is in fact a complex of fourteen species: Trichosiopsis andreae, Trichosiopsis orientis, Trichosiopsis cavernarum, Trichosiopsis coloniae, Trichosiopsis defecta, Trichosiopsis erinaceus, Trichosiopsis finjae, Trichosiopsis kleebergi, Trichosiopsis nova, Trichosiopsis paradisi, Trichosiopsis phoenix, Trichosiopsis rejecta, Trichosiopsis suecica.

For that reason, the current distribution list, based on literature records, is pretty much unreliable. Most of the specimens will need to be verified for their correct identification.

Etymology

reiectus lat. = objectionable.

Ecology

Trichosiopsis rejecta is a common and widespread forest species and was bred from dead wood.

Note

The record from Bulgaria is based on the distribution of the BIN on BOLD.
