Dolerus asper Zaddach, 1859 and Dolerus brevicornis Zaddach, 1859 (Hymenoptera: Tenthredinidae), with notes on their phylogeny

European Journal of Entomology, 2004
Concordant differences in morphology, phenology and RAMS markers, as well as in sequenced mtDNA (COI, COII, cytb) and nuclear DNA (ITS2) fragments, indicate that Dolerus asper Zaddach, 1859 and Dolerus brevicornis Zaddach, 1859 are valid species.

Molecular phylogenetics of Thymelaeaceae‐Thymelaeoideae: Resolving the paraphyly of Gnidia and a new monophyletic generic classification for the group

TAXON, Volume 75, Issue 4, August 2026.
Abstract Earlier phylogenetic analyses of the family Thymelaeaceae using combined plastid (matK, rbcL, rps16, trnL‐F) and nuclear (ITS) regions showed that the African‐Malagasy genus Gnidia was extensively polyphyletic in relation to the southern African genera Lachnaea, Passerina and Struthiola, as well as to other Southern Hemisphere genera such as ...

Molecular investigation of the phylogenetic placement of Kartalinia and a revision of Bituminaria (Fabaceae: Psoraleeae)

TAXON, Volume 75, Issue 4, August 2026.
Abstract The genus Kartalinia was described to accommodate a single, obscure species, Psoralea acaulis, based on its unique morphology and karyology. No concerted molecular phylogenetic studies were available for this species at the time, and therefore its phylogenetic position was uncertain.

All pieces together now? A phylogenomic analysis and tribe‐level classification of the heterogeneous family Plantaginaceae

TAXON, Volume 75, Issue 4, August 2026.
Abstract The plant family Plantaginaceae comprises approximately 2100 species in 106 genera, representing around 1% of all eudicots. The current circumscription of the family has been established in recent decades based on insights from DNA‐based phylogenetic analyses, which have united genera previously considered unrelated.

Taxonomic complexity in the parasitic plant genus Cistanche: Evidence from phylogenomics

TAXON, Volume 75, Issue 4, August 2026.
Abstract “Desert hyacinths” (genus Cistanche) are striking parasitic plants of historical and cultural importance that include species traded widely for herbal medicine. Despite the need for robust taxonomy, the application of names in the genus remains confused.

Scrutinizing the Wallacean shortfall: global gaps in snake occurrence data across space and environment

Ecography, Volume 2026, Issue 7, July 2026.
Occurrence records are fundamental for ecological and evolutionary research, providing key information on species' geographic ranges. However, these records are often taxonomically, spatially, and temporally biased, requiring caution in their use. Here, we analysed the spatial coverage of occurrence records for over 3500 snake species worldwide to ...

On the botanical history and nomenclature of the New World genus Piscidia (Fabaceae)

Nordic Journal of Botany, Volume 2026, Issue 7, July 2026.
Piscidia L. (Fabaceae) is a New World genus with nine recognized taxa (seven species and two varieties). The previous nomenclatural revisions, made in 1910 and in 1969, are revisited here. The names Derris grandifolia Heyde & Lux ex Donn.Sm. and P. cubensis Urb. required step II lectotypifications, with an epitype for the latter name.

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1304-1321, July 2026.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...
