Based on the examination of type specimens and non-type material collected from various localities of southern China, we found these two congeners were misidentified in many previous publications. Due to the restricted distribution and limited population size of R. fuscipes in China, most taxonomic, biological, and biocontrol studies conducted under the name Harpactor fuscipes or Rhynocoris fuscipes should be instead attributed to R. costalis. To address this confusion regarding these two species, the present study clarifies the taxonomic status of the two controversial species\u2014R. costalis and R. fuscipes. Additionally, a new species, Rhynocoris minutus Liu, Zhao &amp; Cai sp. nov., collected from southwestern China, is described and illustrated. A key to the 13 species in Rhynocoris currently recorded in China is provided.<\/jats:p>","DOI":"10.3390\/insects16080823","type":"journal-article","created":{"date-parts":[[2025,8,8]],"date-time":"2025-08-08T11:41:53Z","timestamp":1754653313000},"page":"823","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Comments on Two Controversial Oriental Assassin Bug Species of the Genus Rhynocoris (Heteroptera: Reduviidae: Harpactorinae), with the Description of R. minutus sp. nov. from China"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-3251-6236","authenticated-orcid":false,"given":"Huaiyu","family":"Liu","sequence":"first","affiliation":[{"name":"State Key Laboratory of Agricultural and Forestry Biosecurity, MOA Key Lab of Pest Monitoring and Green Management, College of Plant Protection, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3393-0338","authenticated-orcid":false,"given":"Zhuo","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Agricultural and Forestry Biosecurity, MOA Key Lab of Pest Monitoring and Green Management, College of Plant Protection, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoyang","family":"Xiong","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Agricultural and Forestry Biosecurity, MOA Key Lab of Pest Monitoring and Green Management, College of Plant Protection, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaoyang","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Agricultural and Forestry Biosecurity, MOA Key Lab of Pest Monitoring and Green Management, College of Plant Protection, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8590-1753","authenticated-orcid":false,"given":"Hu","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Agricultural and Forestry Biosecurity, MOA Key Lab of Pest Monitoring and Green Management, College of Plant Protection, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9315-2756","authenticated-orcid":false,"given":"Ping","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Environment Change and Resources Use in Beibu Gulf, Ministry of Education, Nanning Normal University, Nanning 530001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wanzhi","family":"Cai","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Agricultural and Forestry Biosecurity, MOA Key Lab of Pest Monitoring and Green Management, College of Plant Protection, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,8]]},"reference":[{"key":"ref_1","first-page":"i\u2013x","article-title":"Systematic catalogue of the Reduviidae of the world (Insecta: Heteroptera)","volume":"1","year":"1990","journal-title":"Caribbean J.
