Name
Oxapampeus Roewer,1963 new subfamilial assignment – Wikispecies link – Pensoft Profile
- Oxapampeus Roewer, 1963: 62; Kury 2003[1]: 135; (type species: Oxapampeus weyrauchi Roewer, 1963).
Diagnosis
Based on external morphology, Oxapampeus resembles Pachylinae with three scutal areas (subfamily classical diagnosis is the presence of four areas) and scutal area III with a paramedian pair of spines, such as Corralia Roewer, 1913, Diconospelta Canals, 1934, Haversia Roewer, 1913, Huassampilia Roewer, 1913, Neogonyleptes Roewer, 1913, Spinivunus Roewer, 1943, and two species of Sadocus Sørensen, 1886 (Sadocus conspicillatus and Sadocus polyacanthus). However, Oxapampeus can be distinguished from those genera by the combination of the following characters: ocularium with a paramedian pair of pointed tubercles; frontal hump on anterior border of dorsal scutum moderately developed; scutal areas I–II each with a paramedian pair of enlarged tubercles; posterior margin of dorsal scutum straight; and free tergites I–III unarmed.
Taxonomical note
Oxapampeus has been included in Gonyleptinae due to the presence of three scutal areas on the dorsal scutum and absence of autapomorphies of other gonyleptidean subfamilies. However, its penis does not present the typical gonyleptine pattern. In addition, its ventral plate, with slightly concave lateral sides, as well as the absence of dorsally projected basal lobes, makes it resemble several Andean Pachylinae male genitalia.
Composition
Monotypic.
