Liothrips jatrophae   nom.nov.

Rhynchothrips brevitubus Moulton, 1929: 19   . Homonym of Liothrips brevitubus Karny, 1912: 156   .

Female macroptera. Body, legs and antennae dark brown, antennal segment III with irregular paler areas ( Fig. 9 View FIGURES 6 – 12 ); major setae mainly brown; distal two-thirds of fore wing pale, basal third weakly shaded but brown around sub-basal setae; clavus brown.

Antennae typical of genus but relatively short, with one sense cone on segment III and three on IV. Head dorsally longer than wide ( Fig. 7 View FIGURES 6 – 12 ), first ocellus overhanging interantennal projection; postocular setae weakly capitate, shorter than dorsal eye length; maxillary stylets close together in middle of head, retracted anterior to postocular setal bases; mouth cone 30% longer than dorsal head length, extending to mesopresternum.

Pronotum transverse ( Fig. 8 View FIGURES 6 – 12 ), smooth medially with median longitudinal apodeme, reticulate near anterior and posterior margins; posteroangular and epimeral setae longer than the other three pairs; all weakly capitate. Mesonotum transversely reticulate, lateral setae small. Metanotum reticulate, median setae long and pointed ( Fig. 11 View FIGURES 6 – 12 ). Fore tarsus with short, broadly-based tooth ( Fig. 6 View FIGURES 6 – 12 ). Fore wing with 10–12 duplicated cilia; sub-basal setae capitate, arising in a straight line. Prosternal ferna widely separated; mesopresternum reduced to two slender triangles; metathoracic sternopleural sutures variable from short to long.

Pelta triangular ( Fig. 11 View FIGURES 6 – 12 ), reticulate, recessed slightly into tergite II, with paired campaniform sensilla; tergites II – VII each with two pairs of wing-retaining setae, but anterior pair on each tergite smaller than posterior pair ( Fig. 12 View FIGURES 6 – 12 ); tergites transversely reticulate; tergite IX setae S1 shorter than tube.

Measurements (Female macroptera in microns). Body length 2300. Head, dorsal length 225; width across cheeks 195; ventral length to mouth cone apex 500; postocular setae 65. Pronotum, length 160; width 280; major setae: am 40, aa40, ml 45, epim110, pa 95. Mesonotal lateral setae 35. Metanotal median setae 60. Fore wing length 900; sub-basal setae 35, 50, 65. Tergite IX setae S1 95, S2 100. Tube length 155. Antennal segments III –VIII length 70, 70, 68, 68, 55, 30.

Female microptera. Very similar to macroptera, ocelli well developed; metascutum more transverse ( Fig. 10 View FIGURES 6 – 12 ); fore wing lobe 160 microns.

Male macroptera and microptera. Similar to female but smaller; fore tarsal tooth scarcely larger; sternite VIII largely occupied by pore plate; tergite IX setae S2 stout and 60% as long as S1.

Specimens studied: Mexico, Sinaloa State, Mazatlan, paratype female microptera of brevitubus Moulton   , from deformed leaves of unknown plant, 26.vii.1927 (Ferris), in The Natural History Museum, London   . Mexico, Chiapas State, Tapachula , 3 female, 2 male macropterae, 9 female, 7 male micropterae, from distorted leaves of Jatropha curcas   [ Euphorbiaceae   ], 13.i.2015 (A. Goldarazena), in Australian National Insect Collection, Canberra, and the Natural History Museum, London.
