Taxonomic review and illustrated key to identify species of Thysanoptera in subfamily Panchaetothripinae (Thripidae) from the Philippines

Abstract

The paper provides a review of 16 species in 12 genera under subfamily Panchaetothripinae (Thysanoptera: Thripidae) from the Philippines including new host plant records for Selenothrips rubrocinctus (Giard). Identification keys to genus and species were developed using morphology-based diagnostics of adult female thrips. Photomicrographs of female, and male thrips when available are provided. Reviewed and redefined are the morphological characteristics of Astrothrips aucubae Kurosawa, Astrothrips globiceps (Karny), Astrothrips tumiceps Karny, Caliothrips striatopterus (Kobus), Copidothrips octarticulatus (Schmutz), Elixothrips brevisetis (Bagnall), Helionothrips annosus Wang, Helionothrips guttatus Reyes, Helionothrips kodaliphilus (Ramakrishna & Margabandhu), Heliothrips haemorrhoidalis (Bouche), Hemingia glandula Reyes, Panchaetothrips stepheni Reyes, Phibalothrips peringueyi (Faure), Retithrips javanicus Karny, Rhipiphorothrips pulchellus Morgan, and Selenothrips rubrocinctus (Giard). Species identity confirmation using molecular techniques is recommended for the three species of Helionothrips Bagnall. All 16 species of thrips infest crop plants, fruit trees, grasses, and ornamentals. Caliothrips striatopterus (Kobus), Heliothrips haemorrhoidalis (Bouche), and Selenothrips rubrocinctus (Giard) are pests of mangosteen, and other high value crops in the Philippines.
