Host Specificity Studies on<i>Gynaikothrips</i>(Thysanoptera: Phlaeothripidae) Associated with Leaf Galls of Cultivated<i>Ficus</i>(Rosales: Moraceae) Trees

Ten species from Australia in or related to the genus Gynaikothrips are discussed. Variation among specimens of the pest species on Ficus trees, the ficorum/uzeli complex, is examined with the conclusion that recognition of these two species remains questionable. Two species related to this complex are newly recorded from Australia, insulsus Priesner and luzonensis Priesner, and edentatus Priesner is placed as a syn.n. of ficorum. Two new Gynaikothrips are described, jasmini sp.n. and platypodae sp.n., and additamentus Karny is transferred from Gynaikothrips to Eilapinothrips gen.n. A new species of Agynaikothrips is described as the third known member of this genus, lorieni sp.n., and Liothrips umbratus Hood comb.rev. is returned to this original genus from Gynaikothrips. Two species described in Gynaikothrips from the Philippines, capitulatus Reyes and pedanus Reyes, are transferred to the genus Teuchothrips. The monobasic genus, Aiganothrips Bhatti, is considered a syn.n. of Gynaikothrips, and the monobasic genus, Jennythrips Bhatti, is considered a syn.n. of Liothrips.

“…Currently there are 41 species listed in Gynaikothrips (ThripsWiki 2020), all from the Asian tropics, but only two of these are known from Taiwan. These two species are both found widely around the world galling or folding the leaves of Ficus species (Tree et al 2015). The head is longer than wide with the maxillary stylets retracted only into the basal one third, the pronotum often has twisted transverse striae forming several rounded or oval spots, and the fore tarsal tooth is well-developed in males but smaller or even absent in females.…”

“…Generally, the pronotal epimeral and posteroangular setae are equally long in G. uzeli, whereas in G. ficorum the posteroangular setae are much shorter than the epimerals. However, there is considerable variation within and between populations (Tree et al 2015). Sometimes useful for distinguishing these two species is the colour of the fore wings (Mound et al 1995), hyaline in ficorum but shaded in uzeli, and the presence on tergite III of 5-6 pairs of accessary setae in ficorum but of 7-8 pairs in uzeli.…”

This paper lists from Taiwan 11 genera and 28 species of Thysanoptera of the Liothrips lineage. A key is provided to the 11 genera, and Psephenothrips baiheensis sp.n. and P. cymbidas sp.n. are described. A key to the 12 Liothrips species recorded from Taiwan is provided, with two new species, L. dayuilinensis sp.n. and L. hsuae sp.n. One new combination is presented, Liophloeothrips terminaliae (Moulton) comb.n., and Psephenothrips leptoceras Okajima from Japan is newly recorded from Taiwan.

“…Gynaikothrips microchaetus is unique among its congeners in having the male pore plate fully occupying both the sternal and tergal surfaces of abdominal segment VIII. Gynaikothrips uzeli seems to be associated with Ficus benjamina, and G. ficorum with both F. microcarpa and F. benjamina (Tree et al 2015). But G. microchaetus was collected and described by Ananthakrishnan and Jagdish (1969) from galls on an unknown Ficus plant.…”

Gynaikothrips microchaetus Ananthakrishnan and Jagadish (1969) was described from Dharwar in Karnataka, and until now has been known only from southern India (Ananthakrishnan & Sen 1980). The original description was based on an unspecified number of syntypes, with no depositary indicated. However, one of the authors (R. Varatharajan) acquired four slides that are labelled by Ananthakrishnan as this species and bear the same collection details as given in the original description. These are assumed to be syntypes, and one female is here designated as lectotype. The other three slides are of males and are considered as paralectotypes. Further, during extensive surveys for thrips at Dampa Tiger Reserve, Mizoram (23.32 0 N 92.13 0 E) and Manipur University campus (24.82 0 N 93.90 0 E) during 2014-18, we have collected both sexes of this species from the leaves of Ficus curtipes. The freshly collected specimens were mounted onto microscope slides in Canada balsam, and identified using the keys provided by Ananthakrishnan and Sen (1980). Hence, the species is illustrated and re-described with additional features, based on the type material together with freshly collected specimens from north eastern India, Manipur and Mizoram. The following abbreviations are used for pronotal setae: am-anteromarginals; aa-anteroangulars; pa-posteroangulars; ml-midlaterals; po-postocular; epim-epimerals; abdominal tergite IX setae S1, S2 & S3-setal pairs I, II and III respectively (S1 nearest the mid-line). Gynaikothrips microchaetus Ananthakrishnan and Jagadish (Figs 1-9)Female macroptera. Body colour mainly brown; femora brown, tarsi yellow; fore tibiae yellow with small brown area at base, mid and hind tibiae brown with distal one-third yellow; tarsi yellow; antennal segments I-II brown, III-VIII uniformly yellow (Fig. 3); pronotal epimeral setae pale to very weakly shaded. Head longer than wide; with two pairs of slender, pointed, po setae not reaching to compound eyes (Fig. 1); po setae vary in length 16-43 microns, and also vary in position such that they are not always in a simple transverse row; maxillary stylets about one-third of head width apart, retracted to base of postocular setae (Fig. 1). Antennal segmentation and sense cones typical of genus. Pronotum epimeral setae well developed, apex weakly expanded (Fig. 2), am setae minute (6-15 microns), aa, ml and pa variable in length (10-30 microns); notopleural sutures complete. Fore tarsal tooth small, directed forwards (Fig. 3). Fore wings parallelsided, with 14-20 duplicated cilia. Prosternal basantra absent; mesopresternum boat shaped; metathoracic sternopleural sutures absent. Pelta triangular (Fig. 4); tergites II-VII with 2 pairs of sigmoid wing-retaining setae (Fig. 7); tube length variable, anal setae shorter than tube (Fig. 6).Measurements (lectotype female in microns). Body length 2545. Head, length 275; width 222; po, inner pair 30; outer pair 20. Pronotum, length 158; width 282; major setae-am 15, aa 20, pa 24, ml 25, epim 96. Mesonotum lateral setae 30.
