It is a helmetiid arthropod closely related to trilobites, notable for its crown-like pygidium (tail shield) that inspired its species name. It belongs to the extinct order Helmetiida within the clade Conciliterga, a group of trilobite-like artiopods.<ref name="Zhao2014">{{Cite journal |last1=Zhao |first1=Fangchen |last2=Hu |first2=Shixue |last3=Zeng |first3=Han |last4=Zhu |first4=Maoyan |date=March 2014 |title=A New Helmetiid Arthropod from the Early Cambrian Chengjiang Lagerstätte, Southwest China |url=https://www.researchgate.net/publication/261474798 |journal=Journal of Paleontology |language=en |volume=88 |issue=2 |pages=367–370 |doi=10.1666/13-103 |bibcode=2014JPal...88..367Z |issn=0022-3360}}</ref> Name origin: The genus name ''Haifengella'' comes from Haifeng village near the fossil site; the species epithet ''corona'' (Latin for “crown”) refers to the crown-shaped outline of its pygidium. ''Haifengella'' has six thoracic tergites and two pairs of tail spines.<ref name="Zhao2014"/> Each of the thoracic tergites exhibits a pair of long spines projecting from the posterolateral corners.<ref name="Zhao2014" />
In 2025, Losso, Caron Ortega-Hernández in their reanalysis of ''Helmetia expansa'' recovered ''Haifengella'' as a sister taxon of ''Rhombicalvaria''.<ref>{{cite journal |first1=Sarah R. |last1=Losso |first2=Jean-Bernard |last2=Caron |first3=Javier |last3=Ortega-Hernández |date=4 April 2025 |title=''Helmetia expansa'' Walcott, 1918 revisited – new insights into the internal anatomy, moulting and phylogeny of Conciliterga |journal=Journal of Systematic Palaeontology |volume=23 |issue=1 |article-number=2468195 |doi=10.1080/14772019.2025.2468195 |doi-access=free |bibcode=2025JSPal..2368195L }}</ref>
