Diagnosis

Males of A. vernalis are distinguished from congeners by several morphological characters, including the structure of the male genitalia (Fig. 10; see also Chandler (2001), Fig. 107-109), while females are recognised by peculiar abdominal marking ( Chandler 2001, fig. 110, 111).

Distribution

Europe: Moscow province of Russia, Czech and Slovak Republics, Switzerland ( Chandler 2001), Finland ( Ståhls and Kahanpää 2006) and Romania ( Tkoč and Roháček 2014).

Ecology

Virtually unknown. Other Agathomyia species assumed to develop internally in polypore fungi ( Chandler 2001). In the Czech Republic, adults were registered in pyramidal (emergence) traps ( Tkoč and Barták 2013). This species was collected from aspens fallen 8-10 years ago. The species did not show any preferences either to the trunk size or tree mortality mode (windfall vs. windbreak) Table 1. Its occurrence positively correlated with the following fungi: Fomitopsis pinicola (RS=0.99, P<0.01), Cerioporus leptocephalus , Royoporus badius , Trametes trogii , Punctularia strigosozonata (RS=0.73, P<0.01), Xenasma rimicola , Kurtia argillacea , Resinicium bicolor , Tomentella badia , T. crinalis and T. lapida (RS=0.61, P<0.05).

Conservation

Red-listed in Czech Republic, category EN ( Farkac et al. 2005).
