Diagnosis
Trichosiopsis fuscipalpa is a medium sized, slender species. It can be readily recognized by the long, tiny, yellow legs and long abdomen and by the large and broad wings with a reduced anal lobe. By the shape of the male genitalia Tr. fuscipalpa is similar to Trichosiopsis rejecta, Trichosiopsis defecta and Trichosiopsis finjae, having an obtuse angle on the outer side of the gonostyles above the apical tooth. It differs from these species by the longer antennae, the basally more rounded gonostyles and the not elongated hairs at the base of the hypopygium. The variant with broader form of the gonostyles with a less distinct apical angle (Fig. 2) reminds of species of the Tr. dimera complex, especially Trichosiopsis viatica and Trichosiopsis subpilosa, which can be distinguished apart from the shorter antennae by the shorter palpi and the more setose bM vein respectively. Trichosiopsis cerifera, which has still longer antennae, can be distinguished by the more parallel gonostyli.
DNA Barcoding
The COI sequences are assigned to four different BINs:
- BIN BOLD:ACC1319 (average distance 0.13%, max. 0.31%, n=7, K2P: 3.69%)
- BIN BOLD:ACE2641 (average distance 0.06%, max. 0.15%, n=5, K2P: 6.62%)
- BIN BOLD:ACM7016 (average distance 0.27%, max. 1.12%, n=36, K2P: 3.69%)
- BIN BOLD:ACQ8733 (average distance 0.09%, max. 0.17%, n=11, K2P: 8.04%)
Discussion
The shape of the gonostylus in Tr. fuscipalpa is variable, which was discussed by Heller (2004[5]: 241). The holotype and specimens from northern Finland (Fig. 3) have more elongate gonostyli than the more common form in Central Europe (fig. 2). But otherwise no distinctive differences were observed, so both variants are still treated as conspecific.
Genetic analysis has now shown, that Tr. fuscipalpa is a complex of of different phylogenetic entities. DNA barcoding revealed four different genetic clusters with K2P distances of more than 3.5% each. Usually such distances may qualify for distinct species. There are even a few morphological differences, but not in all cases a secure identification can be achieved. For pragmatic reasons, the genetic variants are treated as subspecies, although they are probably good species. More detailed studies are needed to resolve this complex of cryptic or semi-cryptic species.
Etymology
fuscus lat. = brown, making reference to the colour of the palpi.
Ecology
Trichosiopsis fuscipalpa is one of the most common and widespread forest species in Europe. The species was bred from dead wood (Mohrig et al., 1979[1]; Irmler et al., 1996[6]: 146 [as Trichosia pilosa])
