His national contributions included several checklists, together with his more complex contribution within the Fauna of Czechoslovakia. On the 22nd of April 2006 Jaroslav Pelikán celebrated his 80th birthday

Convoluted maxillary stylets among Australian Thysanoptera Phlaeothripinae associated mainly with Casuarinaceae trees

The diversity is reviewed of Phlaeothripinae in Australia with unusually long or convoluted maxillary stylets. This comprises a total of 28 species in eight genera, including Enigmathrips carnarvoni gen et sp.n., Adrothrips latrarei sp.n., A. lihongae sp.n., A. madiae sp.n., A mitcheli sp.n., A. vernoni sp.n., and A. westoni sp.n., also Heligmothrips exallus sp.n., H. macropus sp.n., H. narrabri sp.n. and H. xanthoskelus sp.n., and Iotatubothrips daguilari sp.n. Among Phlaeothripinae, such exceptionally long feeding stylets are known only from Australia and have evolved independently within the unrelated genera Adrothrips and Heligmothrips in association with the green branchlets of Casuarinaceae species. A few species appear to have diverged in their feeding habits and have adapted to fungal-hyphal feeding on the trunks of trees

Structured lipids on a coccid wax (Coccoidea, Eriococcidae)

Maßgeschneiderte Triglyceride, die aus zwei kurzkettigen und einem langkettigen Acylrest bestehen, werden seit einigen Jahren als so genannte Designer-Lipide produziert, vorwiegend für den Einsatz in Medizin und Diätik. Zunehmend finden entsprechende Triglyceride aber auch als Zusatzstoffe für Nahrungsmittel Verwendung, um deren physikochemische Eigenschaften gezielt zu verändern. Die vorliegende Arbeit zeigt, dass eine Schildlausart solche Triglyceride ebenfalls funktionell einsetzt. Die Weibchen von Callococcus banksiae (MASKELL) umgeben sich, wie für Schildläuse nicht ungewöhnlich, mit einer Masse aus Wachsfäden. Diese Masse bedeckt zeitweise die Äste des ostaustralischen Kanuka-Strauches (Kunzea ericoides). Im Gegensatz zu den Wachsausscheidungen anderer australischer Schildläuse, meiden fouragierende Ameisen das Wachs von C. banksiae. Das hängt damit zusammen, dass die Wachsfäden dieser Art aufgrund ihrer besonderen Zusammensetzung „klebrig“ sind. Außerdem interessant ist, dass sich Thysanopteren der Art Teuchothrips fuscipennis (MOULTON) (Phlaeothripidae) in der Umgebung der Schildläuse und im Wachs aufhalten. Sie können sich frei und problemlos auf dem Wachs bewegen ohne festzukleben.banksiae (Maskell) (Coccoidea, Eriococcidae). These waxy masses, measuring up to 10mm in diameter, are sometimes abundant in eastern Australia on the stems of the host plant (Kunzea ericoides), and the wax is of interest biologically for two reasons. First, unlike many coccid species that secrete waxy coverings, ants do not attend C. banksiae despite often walking near them on the plant stems. Second, a particular species of thrips, Teuchothrips fuscipennis (Moulton) (Phlaeothripidae) breeds beneath the waxy mass, and the larvae and adults move quickly and freely between the wax filaments without adhering in any way. The wax surface is the subject of current investigations, for which this report on taylor-made triglycerides provides a base

Taxonomic review of the Oriental genus Phylladothrips Priesner (Thysanoptera, Phlaeothripidae)

Species of the Oriental subtropical and tropical genus Phylladothrips of fungus-feeding thrips exhibit some diagnostic character states, usually with abdominal tergite VIII bearing two pairs of wing-retaining setae and male tergite IX setae S2 about as long as S1. These species are quite small, and the maxillary stylets unusually broad for Phlaeothripinae. Phylladothrips trisetae sp. nov. from Xizang, China and P. selangor sp. nov. from Selangor, Malaysia are described, and P. fasciae is newly recorded from China. All 11 species in this genus are revised with an illustrated key

Inventory of Thysanoptera Collected from French Polynesia.

v. ill. 23 cm.QuarterlyA survey for Thysanoptera was conducted in the Society (Tahiti, Moorea, and Raiatea), Marquesas (Hiva Oa, Nuku Hiva, Ua Huka, and Ua Pou), and Austral islands (Rurutu and Tubuai) archipelagos in French Polynesia from September 2003 to November 2005. At least 55 thrips species in 36 genera and three families were identified from 823 slide-mounted specimens that were collected from 61 host plants in 33 families. Twelve species are considered to be important pests. The greatest diversity of species, 43 (77%), was collected from the Society Islands, with 60% being recorded from Tahiti alone. Species diversity was intermediate in the Marquesas Islands at 43% (24 species collected), with 35% or 19 species being recorded from Nuku Hiva. Lowest diversity was recorded for the Austral Islands, with 38% or 21 species being found in that archipelago. Less than 10% of collected species are likely to be native, with the majority of identified thrips (>90%) in French Polynesia representing a high diversity of exotic species (leaf, flower, and fungus feeders, and four predatory species) that have successfully infiltrated other island groups in the South Pacific.Survey results and subsequent estimates of thrips species diversity in French Polynesia should be interpreted with caution due to uncontrolled variation in sampling intensity that was affected by survey duration, time of year, and visitation frequency to islands

Resolving the confused identity of Frankliniella panamensis (Thysanoptera: Thripidae)

La figure de Jules César dans les Essais Dans les débats idéologiques en Italie, la figure de Jules César se situe au cœur de la grande polémique entamée par les humanistes florentins contre leurs homologues milanais et contre les visées expansionnistes de la tyrannie incarnée par les Visconti, et César est un des personnages les plus cités chez Machiavel.

Figures 22-26 from: Mound LA (2017) Intra-specific structural variation among Hawaiian Hoplothrips (Thysanoptera, Phlaeothripidae), with ten new synonymies and one new species. ZooKeys 722: 137-152. https://doi.org/10.3897/zookeys.722.22131

Most of the 16 fungus-feeding species described from the Hawaiian Islands and now placed in the genus Hoplothrips were based on very few and incomplete specimens. The descriptions were published long before any studies on the biology and structural variation of fungus-feeding Phlaeothripinae. Ten of these species are here placed into synonymy, and doubts are expressed concerning the identity of some others. One new polymorphic species is described and compared to a species known only from Florida. In the absence of comprehensive studies on the Hoplothrips fauna of North America, there is little evidence of endemicity or radiation on Hawaii within this genus

Scolothrips latipennis Priesner 1950

<i>Scolothrips latipennis</i> Priesner 1950: 54 <p> The type specimens of this species (in SMF) were collected at Cairo, Egypt feeding on <i>Eotetranychus cucurbitacearum</i> (Tetranychidae) on <i>Citrullus</i> leaves. It was noted at that time that <i>latipennis</i> sometimes co-existed on the same leaf as <i>Scolothrips longicornis</i>, and collections from Egypt in 1987 from soy bean leaves confirmed this association (in BMNH). These two species are readily distinguished from <i>sexmaculatus</i> because the pronotum lacks a pair of posteromesad discal setae (Fig. 2). <i>S. latipennis</i> is another member of the genus that, in fully mature adults, has at least the anterolateral areas of the pterothorax shaded or even dark brown. In fully mature females the abdominal terga are uniformly light brown to brown, although the legs are almost uniformly yellow, and the pronotum is distinctively paler or even yellow. This species is widely reported in countries of the Mediterranean region (zur Strassen, 2003), and is here newly recorded from Australia: two females have been studied taken from <i>Prunus</i> leaves in New South Wales [near Young in 1965 (ANIC), and near Leeton in 2001 (NSWO)].</p>Published as part of <i>Mound, Laurence A., 2011, Species recognition in the genus Scolothrips (Thysanoptera, Thripidae), predators of leaf-feeding mites, pp. 45-53 in Zootaxa 2797</i> on page 50, DOI: <a href="http://zenodo.org/record/204061">10.5281/zenodo.204061</a&gt

Thrips acaciae Trybom

Thrips acaciae Trybom Thrips acaciae Trybom, 1910: 161 Thrips kikuyuensis Trybom, 1912: 6 syn.n. Thrips spadix Hood, 1932: 131 syn.n. Thrips hirtiventris Hood, 1932: 126 This is here interpreted as a widespread and variable species. Faure (1964) recognised that T. hirtiventris from Tanzania was a synonym. Trybom (1912) did not compare T. kikuyuensis from Kenya with T. acaciae that he had described previously (1910) from Namibia (Kalahari). However, a cotype of kikuyuensis has been examined and these two cannot be distinguished satisfactorily. One paratype female of T. spadix has been studied, and this is also considered to be a synonym, despite Hood indicating that the third antennal segment was rather longer. As discussed below, quadridentatus is possibly a further synonym of acaciae. Material recognisable as T. acaciae has been studied from Sudan, Kenya, Tanzania, Zululand, Namibia and Cameroon. Diagnosis. Body and legs brown, tarsi and fore tibiae yellow; antennal segments I–II brown, III mainly yellow, IV–V yellow at base; forewing shaded with small white oval near base. Antennae 7 -segmented. Ocellar setae III arising outside triangle (Fig. 1), shorter than distance between hind ocelli. Pronotum with many transverse sculpture lines not closely spaced, about 40 discal setae; posteroangular setae about 0.3 as long as pronotum; with 4 or 5 pairs of posteromarginal setae. Mesonotal anteromedian campaniform sensilla present. Metanotum medially with longitudinal row of large slightly elongate reticles (Fig. 2), median setae near but not at anterior margin, campaniform sensilla present or absent. Forewing first vein with 2–4 setae on distal half; clavus with 5–8 marginal setae and 1 discal seta (Fig. 2). Abdominal tergites with sculpture lines extending to setae S 1; VIII posterior margin with weak but complete comb; pleurotergites with no discal setae, but with weakly dentate or slender microtrichia on widely spaced lines of reticulation (Fig. 3); sternites III–VII with more than 24 short discal setae in two irregular rows.Published as part of Mound, Laurence A., 2010, Species of the Genus Thrips (Thysanoptera, Thripidae) from the Afro-tropical Region, pp. 1-24 in Zootaxa 2423 on page 5, DOI: 10.5281/zenodo.19453
