(Tylenchomorpha: Allantonematinae), is described from thrips collected from flowers in Hainan Province, China. The species is identified using an integrative approach combining detailed morphology, molecular phylogenetic analyses, and biological observations.\n                    <jats:italic>Thripinema usitatum<\/jats:italic>\n                    n. sp. exhibits pronounced sexual dimorphism and a complex life cycle, including obese parasitic females, vermiform infective females, and free-living males with degenerate feeding structures within the body of thrips. The new species is distinguished from its congeners by the absence of a stylet in free-living males, a distinctive two-part bursa extending nearly to the tail terminus, and characteristic shapes of parasitic females and male tails. Molecular characterization was performed using three markers (18S rRNA, 28S D2\u2013D3 rRNA, and mitochondrial cytochrome c oxidase subunit I, mt\n                    <jats:italic>COI<\/jats:italic>\n                    ). Phylogenetic analyses based on 28S D2\u2013D3 rRNA and mt\n                    <jats:italic>COI<\/jats:italic>\n                    partial sequences consistently recovered\n                    <jats:italic>T. usitatum<\/jats:italic>\n                    n. sp. as a well-supported, monophyletic lineage clearly separated from other entomophilic nematodes. Among the markers examined, mt\n                    <jats:italic>COI<\/jats:italic>\n                    provided the highest discriminatory power. Biological observations revealed that\n                    <jats:italic>T. usitatum<\/jats:italic>\n                    n. sp. infects thrips at all developmental stages, with a strong prevalence in adult females. Multiple nematode life stages frequently co-occurred within individual hosts, and infection intensities ranged from 1 to 433 nematodes per thrips. These results expand the known diversity of\n                    <jats:italic>Thripinema<\/jats:italic>\n                    and provide a robust framework for future systematic and ecological studies of thrips-parasitic nematodes.\n                  <\/jats:p>","DOI":"10.1017\/s0022149x26101515","type":"journal-article","created":{"date-parts":[[2026,6,18]],"date-time":"2026-06-18T08:01:12Z","timestamp":1781769672000},"source":"Crossref","is-referenced-by-count":0,"title":["Integrative taxonomy of\n                    <i>Thripinema usitatum<\/i>\n                    n. sp., a new entomoparasitic nematode associated with the bean flower thrips\n                    <i>Megalurothrips usitatus<\/i>\n                    in China"],"prefix":"10.1017","volume":"100","author":[{"given":"W.-H.","family":"Chen","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05v9jqt67","id-type":"ROR","asserted-by":"publisher"}],"name":"South China Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.-J.","family":"Qiu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05v9jqt67","id-type":"ROR","asserted-by":"publisher"}],"name":"South China Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Y.-F.","family":"Lu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05v9jqt67","id-type":"ROR","asserted-by":"publisher"}],"name":"South China Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.-H.","family":"Wu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/003qeh975","id-type":"ROR","asserted-by":"publisher"}],"name":"Chinese Academy of Tropical Agricultural Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2299-5980","authenticated-orcid":false,"given":"H.-P.","family":"Pan","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05v9jqt67","id-type":"ROR","asserted-by":"publisher"}],"name":"South China Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.-L.","family":"Xu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05v9jqt67","id-type":"ROR","asserted-by":"publisher"}],"name":"South China Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,6,18]]},"reference":[{"key":"S0022149X26101515_r4","doi-asserted-by":"publisher","DOI":"10.1186\/s42483-024-00223-2"},{"key":"S0022149X26101515_r1","doi-asserted-by":"publisher","DOI":"10.1603\/0022-0493-95.4.668"},{"key":"S0022149X26101515_r12","first-page":"4439","article-title":"Analysis of annual population dynamics of Megalurothrips usitatus on cowpea in Hainan","volume":"58","author":"Huang","year":"2025b","journal-title":"Scientia Agricultura Sinica"},{"key":"S0022149X26101515_r2","doi-asserted-by":"publisher","DOI":"10.1603\/0046-225X-32.4.853"},{"key":"S0022149X26101515_r11","first-page":"54","article-title":"Impact of Megalurothrips usitatus population density on cowpea yield and quality","volume":"45","author":"Huang","year":"2025a","journal-title":"China Plant Protection"},{"key":"S0022149X26101515_r5","first-page":"89","article-title":"Thripinema khrustalevi sp. n.
