Diagnosis

Leptosciarella rejecta is a large species. In its typical form it is characterized by the shiningly yellow legs with 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 gonostyles is not as straight as in Leptosciarella scutellata, which has nearly rectangular gonostyles. Leptosciarella defecta is very similar, but has dark coxal bristles and more slender and tapered gonostyles with a narrower front part over the apical tooth, just as Leptosciarella fuscipalpa. The smaller variant of this species, which has darker legs and shorter palpi, is here treated separately as Leptosciarella echinata.

Discussion

This species was originally described in the female sex only, so that the correctness of the present species concept is not absolutely sure. The lectotype was not studied again, but the interpretation of Mohrig & Menzel (1997: 62-65, Fig. 11) is followed here. The studied material agrees with the figures and the redescription. The species is 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 Leptosciarella pilosa]. All these authors point out the apparent variability of this species and it is not clear, how the real species limits are. DNA barcoding might be be a useful method to solve this species complex. The here employed treatment of Le. echinata as a distinct species makes the following distribution list unreliable, if this concept is followed.

Etymology

reiectus lat. = objectionable.

Ecology

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