Background
- Oliarus pinicolus Osborn, 1926, a poorly documented planthopper species, was originally described from western Cuba, associated with Cuban pine (Pinus cubensis).
- The New World cixiid genus Melanoliarus Fennah, 1945, is known for its extensive diversity.
Purpose Of The Study
- To redescribe and illustrate Oliarus pinicolus, including its male terminalia, for the first time.
- To re-evaluate the taxonomic placement of Oliarus pinicolus within the Cixiidae family.
- To provide an updated checklist and taxonomic commentary on Antillean Pentastirini.
Main Methods
- Morphological examination and illustration of male terminalia of Oliarus pinicolus.
- Comparative analysis with related species within the region.
- Designation of a lectotype for Oliarus pinicolus to stabilize its species concept.
Main Results
- Oliarus pinicolus is redescribed and illustrated, with detailed analysis of its male terminalia.
- The species is transferred to the genus Nivcentia Holzinger, 2004, becoming Nivcentia pinicolus comb. nov.
- An amended description of the genus Nivcentia is provided, incorporating characteristics of the newly transferred species.
Conclusions
- The taxonomic placement of Nivcentia pinicolus is clarified, enhancing understanding of the genus Nivcentia.
- The study contributes to the systematic knowledge of Antillean Pentastirini, with illustrations of Cuban pentastirine species.
- This work provides a stable species concept for Nivcentia pinicolus through lectotype designation.
