Lonchaea baechlii MacGowan
Nomenclature
-
Tribe: LonchaeinaeGenus: Lonchaea
SUMMARY
this species has two katepisternal setae but the surstylus
does not bear any prensisetae indicating that it is a true Lonchaea species and does
not belong to the genus Silba Macquart, 1851. it is unclear whether the two kat -
episternal setae in the holotype are a characteristic feature of this species. with bare
eyes, uniserial setulae on the anterior part of the genae, black tarsomeres, pale calypteres,
a single seta on the proepimeron and bare orbital plate this species lies near
species such as Lonchaea chorea (fabricus, 1781) in the european fauna. the antennal
flagellomere is however much shorter than in l. chorea in which the length to
depth ratio is on average 2.0–2.3 to 1 (1.7 to 1 in L. baechlii). the frons is wider in
L. chorea (fabricius,1781) with the frons width to eye width ratio ranging from 1
to 1.8–1 to 1.22 (1 to 2.8 in L. baechlii). this species is however easily differentiated
by examination of the male genitalia, in particular the characteristic two segmented
phallus. this shows some similarities to the phallus shape in Lonchaea
bukowskii czerny, 1934 and Lonchaea ragnari Hackman, 1956 but both of these
species have partly yellow tarsomeres and more than one seta on the proepimeron.
