\u2013 is a forum for advancing the science of phylogenetic systematics. The Society provides the opportunity for diverse workers, from every area of systematics, to debate within a cladistic framework aspects relating to both systematic practices and applications of systematics such as paleontology, historical biogeography, evolutionary morphology, ecology, or conservation biology. Our members combine an interest in the principles of systematics with a strong sense of the importance of empirical work. The exchange of ideas occurs at annual meetings, and in the pages of the Society&#8217;s journal, <a href=\"https:\/\/cladistics.org\/cladistics\/\"><em>Cladistics<\/em><\/a>. The benefits brought to systematics as a field by the Society have been amply documented in the journal since its inception. We expect to continue to benefit systematics into the future.<\/p>\n<p>Membership fees for 2026 are due now \u2013 please visit the <a href=\"http:\/\/cladistics.org\/membership\/\">Membership page<\/a>.<\/p>\n<p>We invite you to follow the WHS Social Media accounts:<\/p>\n<p>Facebook \u2013 <a href=\"https:\/\/www.facebook.com\/p\/The-Willi-Hennig-Society-100064976945167\/\" target=\"_blank\" rel=\"noopener\">The-Willi-Hennig-Society-100064976945167<\/a><\/p>\n<p>Instagram \u2013 <a href=\"https:\/\/instagram.com\/willihennigsociety\" target=\"_blank\" rel=\"noopener\">WilliHennigSociety<\/a><\/p>\n<p>X \/ Twitter \u2013 <a href=\"https:\/\/x.com\/WilliHennigSoc\" target=\"_blank\" rel=\"noopener\">WilliHennigSoc<\/a><\/p>\n<p>X \/ Twitter \u2013 <a href=\"https:\/\/x.com\/CladisticsAlert\" target=\"_blank\" rel=\"noopener\">CladisticsAlert<\/a> \u2013 <em>Cladistics<\/em> journal alert<\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-49syu-187b2ad3469cdda068727c75307bcd92\">\n.flex_column.av-49syu-187b2ad3469cdda068727c75307bcd92{\nborder-width:2px;\nborder-color:#edae44;\nborder-style:solid;\nborder-radius:0px 0px 0px 0px;\npadding:10px 10px 10px 10px;\n}\n<\/style>\n<div  class='flex_column av-49syu-187b2ad3469cdda068727c75307bcd92 av_one_fourth  avia-builder-el-6  el_after_av_one_half  el_before_av_hr  flex_column_div  '     ><p>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-14e3i-4d2d7a71fc5049d89655e94dcc72aaaf\">\n#top .av-special-heading.av-14e3i-4d2d7a71fc5049d89655e94dcc72aaaf{\npadding-bottom:10px;\n}\nbody .av-special-heading.av-14e3i-4d2d7a71fc5049d89655e94dcc72aaaf .av-special-heading-tag .heading-char{\nfont-size:25px;\n}\n.av-special-heading.av-14e3i-4d2d7a71fc5049d89655e94dcc72aaaf .av-subheading{\nfont-size:15px;\n}\n<\/style>\n<div  class='av-special-heading av-14e3i-4d2d7a71fc5049d89655e94dcc72aaaf av-special-heading-h3 blockquote modern-quote modern-centered  avia-builder-el-7  el_before_av_magazine  avia-builder-el-first '><h3 class='av-special-heading-tag '  itemprop=\"headline\"  >Announcements<\/h3><div class=\"special-heading-border\"><div class=\"special-heading-inner-border\"><\/div><\/div><\/div><br \/>\n<div  id=\"avia-magazine-1\"  class='av-magazine av-3adnq-1a5584f59c99e55f31db80dac0504f43  avia-builder-el-8  el_after_av_heading  avia-builder-el-last   avia-builder-el-8  el_after_av_heading  avia-builder-el-last ' ><div class='av-magazine-group sort_all'><article class='av-magazine-entry av-magazine-entry-id-1661 av-magazine-format-standard av-magazine-type-post av-magazine-entry-1 av-magazine-entry-small av-magazine-no-thumb'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class=\"av-magazine-content-wrap\"><header class=\"entry-content-header\" aria-label=\"Post: Hennig XLIII Annual Meeting 2026\"><time class='av-magazine-time updated'  itemprop=\"datePublished\" datetime=\"2026-02-26T02:21:31+00:00\" >February 26, 2026<\/time><h3 class='av-magazine-title entry-title '  itemprop=\"headline\" ><a href='https:\/\/cladistics.org\/2026\/02\/26\/hennig-xliii-annual-meeting-2026\/' title='Link to: Hennig XLIII Annual Meeting 2026'>Hennig XLIII Annual Meeting 2026<\/a><\/h3><\/header><\/div><footer class=\"entry-footer\"><\/footer><\/article><article class='av-magazine-entry av-magazine-entry-id-1625 av-magazine-format-standard av-magazine-type-post av-magazine-entry-2 av-magazine-entry-small av-magazine-no-thumb'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class=\"av-magazine-content-wrap\"><header class=\"entry-content-header\" aria-label=\"Post: Hennig XLII \u2013 program posted\"><time class='av-magazine-time updated'  itemprop=\"datePublished\" datetime=\"2025-07-21T16:04:09+00:00\" >July 21, 2025<\/time><h3 class='av-magazine-title entry-title '  itemprop=\"headline\" ><a href='https:\/\/cladistics.org\/2025\/07\/21\/hennig-xlii-program-posted\/' title='Link to: Hennig XLII \u2013 program posted'>Hennig XLII \u2013 program posted<\/a><\/h3><\/header><\/div><footer class=\"entry-footer\"><\/footer><\/article><article class='av-magazine-entry av-magazine-entry-id-1594 av-magazine-format-standard av-magazine-type-post av-magazine-entry-3 av-magazine-entry-small av-magazine-no-thumb'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class=\"av-magazine-content-wrap\"><header class=\"entry-content-header\" aria-label=\"Post: Hennig XLII - symposia posted\"><time class='av-magazine-time updated'  itemprop=\"datePublished\" datetime=\"2025-05-29T01:25:58+00:00\" >May 29, 2025<\/time><h3 class='av-magazine-title entry-title '  itemprop=\"headline\" ><a href='https:\/\/cladistics.org\/2025\/05\/29\/hennig-xlii-symposia-posted\/' title='Link to: Hennig XLII &#8211;
