Diagnosis Female macropterous; body color mainly brown, with abdominal segments VIII and IX almost black; all tarsi and leg joints lighter, as well as the tube, with an orange-ish shade; antennomeres I–II and base of III yellow, remaining segments brown, almost black at the tip of antennae; fore wings light brown with a darker base, and a paler band medially. Antennae 7-segmented, VII–VIII almost completely fused but with a visible suture between both; antennomere III with 2 and IV with 4 sense cones. Head as long as wide, without elongated setae on cheeks; maxillary stylets wide apart, forming a “V” shape. Prosternum with basantra. Metanotum weakly sculptured, with one pair of long median setae wide apart. Metathoracic sternopleural sutures present. Pelta reticulate, with the posterior margin potentially eroded; abdominal tergites II–VII with 1 pair of wing-retaining setae; tube cone-shaped, a wide base strongly tapering to the apex, about 1.4x as long as basal width. Median abdominal sternites are usually longer than tergites. Fore tarsi with a robust and short tooth. Fore wings without duplicated cilia.

Genus and similar species information Acallurothrips is a genus with over 20 species worldwide, of which three are recorded in Brazil. These thrips have a characteristic tube: short, with a thick base and strongly tapering to the apex, sometimes with short setae laterally. The head is about as wide as long, with maxillary stylets at least one third of head width apart; antennomeres VII and VIII are partially or completely fused; and abdominal sternites are usually longer than the tergite in the same segment. Acallurothrips conifer is distinguished by its lighter tube, with an orange-ish shade, while in the other two Brazilian species the tube is dark brown, almost black. A key to Neotropical species of Acallurothrips is available in Mound & Marullo (1996).
Distribution around the world Described from Trinidad and Tobago. Recorded from Brazil and Panama.
