Type species
Damacornu transversum
gen. et sp. nov.
, by original designation.
Other included species
None.
Diagnosis
A genus of
Odontopygidae
–
Prionopetalini
characterized by the following combination of characters: gonopod coxa with a mesal spineless metaplical shelf, without a basad metaplical spine; telopodital torsotope with a long spine; solenomere whip-like, with a basal spine but otherwise without outgrowths, apically fluted and spiraled; telomere a longitudinally folded lamella; distal half of telomere bent at right angles in relation to basal half, with a row of teeth on internal surface.
Etymology
A composite noun, from
Dama
(fallow deer) and
cornu
(horn, antler), referring to the (slight) resemblance between the gonopod telomere and an antler from the fallow deer,
Dama dama
(Linnaeus, 1758)
. Gender neuter.
Remarks
In the key to genera of “
Odontopyginae
” by
Kraus (1966)
,
Damacornu transversum
gen. et sp. nov.
keys out to the genus
Odontopyge
, and in the key to species of
“Odontopyge”
by
Kraus (1960)
it keys out in couplet 11 (“
O.” citernii
Silvestri, 1898 and
“O.” difficilis
Silvestri, 1895). The new species is, however, clearly different from these two species in which there is no metaplical shelf and the proximal solenomeral spine (
ps
) (“Tibialdorn”) is rudimentary. None of the “orphaned” species assigned to
Odontopyge
by earlier authors (see
Enghoff 2016a
) can be adopted by
Damacornu
gen. nov.
, which for the time being remains monotypic.
