The morphology and chaetotaxy of the first instar larva of the scorpionfly Sinopanorpa tincta (Navás, 1931) are described and illustrated for the first time with the aid of light microscopy and scanning electron microscopy, with particular attention to the mouthparts and their sensilla. A comparison is made with the larvae of other known Mecoptera, especially Panorpa and Neopanorpa in Panorpidae.

In this study, the epidermal types and their distribution on dorsal and lateral petals, the trichome types and their density on sepals of Lathyrus chloranthus, L. digitatus, L. laxiflorus subsp. laxiflorus, L. roseus subsp. roseus, L. sativus, and L. tuberosus, belonging to sections Lathyrus, Lathyrostylis, Pratensis, and Orobon of the genus Lathyrus in Turkey were investigated using light microscopy (LM) and scanning electron microscopy (SEM), and the systematic significance of these characters was evaluated. These taxa, except L. sativus, are studied for the first time under aspects of the petal and sepal micromorphology. Three major epidermal types were recognized on the petal: tabular rugose striate cells (TRS), areolate cells with more or less striations (AS), and papillose conical striate cells (PCS). TRS and AS were further subdivided into three subtypes. TRS was found on the dorsal and lateral petals of L. chloranthus, L. sativus, and L. tuberosus: the dorsal petals of L. roseus subsp. roseus and the lateral petals of L. laxiflorus subsp. laxiflorus, while AS was present on the dorsal and lateral petals of L. digitatus and the lateral petals of L. roseus subsp. roseus. PCS was found only on the dorsal petals of L. digitatus. Three main types of trichomes on the sepal were observed: peltate glandular, capitate glandular, and nonglandular trichomes. The capitate glandular and nonglandular trichomes were further subdivided into three subtypes. The peltate glandular trichomes were present only in L. chloranthus, but absent in the others. The capitate glandular trichomes were found in L. chloranthus, L. laxiflorus subsp. laxiflorus, L. roseus subsp. roseus, and L. tuberosus. The nonglandular trichomes were always present in L. chloranthus and L. laxiflorus subsp. laxiflorus. The present results show that the petal and sepal micromorphology can be used in delimitation of the taxa based on petal and sepal micromorphology.

Palynomorphological characteristics of Campanula lingulata, the Balkan-Carpathian endemic species growing in Serbia, have been investigated using light microscopy and scanning electron microscopy for the first time, in order to provide some information helpful for a better understanding of the taxonomic position of this species within the genus, as well as to contribute to the pollen atlas of Serbian apiflora. The pollen grains are radially symmetrical, isopolar, 3-zonoporate and medium-sized monads oblate-sphaeroidal in shape. Mean of the polar axis (P) is 27.6?1.9 ?m, while the average length of the equatorial axis (E) is 28.8?1.6 ?m. The apertures are operculate. The sculpturing pattern of the exine is microre?ticulate-microechinatae. The exine surface is covered with evenly distributed supratectal spinules of variable length and sparse granules. The longest supratectal spinules are 0.64?0.05 ?m in length and the smallest sculptural elements are less than 0.2 ?m high. The microechinae density per sample area of 5 ?m x 5 ?m averages 17.4?2.4.

The morphology of eggs and first instar larvae of Croce schmidti (Navás, 1927) is described and figured for the first time using light and scanning electron microscopy. The females were collected from Derik, Mardin Province, Turkey and maintained in the laboratory. The eggs are elongate and cylindrical with rounded ends and bear a small terminal micropylar knob. Except for the adhesive materials, the chorion surface is smooth. The newly emerged larva of C. schmidti is characterized by a slightly quadrangular head and short prothorax and has prominent pale dark brown color markings on the metatergites. The body is covered with short brown setae, which include macrotrichia and dolichasters.

AbstractMonodontella giraffae Yorke et Maplestone, 1926 was collected from the biliary duct of liver of a dead giraffe, Giraffa camelopardalis (Linnaeus) from the Tianjin Zoo, Tianjin, China. A redescription of this species was made using light microscopy and scanning electron microscopy (SEM). The lateral alae and the detailed structures of the spicules and genital cone were observed for the first time by SEM. The taxonomic status of the genus is discussed.

The spinning apparatus and silk of <em>Segestria senoculata</em> were studied with the use of scanning electron microscopy and light microscopy, which confirmed the presence of four categories of spigots connected with four types of spinning glands (<em>i.e</em>., <em>Glandulae ampullaceae major, Glandulae ampullaceae minor, Glandulae piriformes and Glandulae pseudaciniformes</em>). New data about the morphology of spinnerets and spigots were obtained for both the adults and nymphal stages of both sexes. For the first time the silken threads of retreats, signal threads and attachment discs of the members of <em>Segestria</em> were subjected to a detailed SEM study. The data resulting from studying the spinning apparatus of <em>S. senoculata</em> was compared to current knowledge of the silk producing systems of families belonging to the Dysderoidea superfamily. Silks that are emitted from spigots in the course of retreat construction are not (similarly to the other dysderoids) processed by the spider’s legs during the subsequent process of hardening. Apart from the major ampullate glands/spigots, segestriids also possess developed minor ampullate glands. Minor ampullate threads are used by <em>S. senoculata</em> spiders when making their signal threads.

The Palaearctic genus Trichomeloe is reviewed and newly defined on the basis of larval and adult characters. Its position among the Lyttini tribe is discussed. Trichomeloe includes eight species, mostly from the Near East. The bionomics of the genus is summarized, together with a key to the species, an annotated catalogue and some taxonomic remarks. T. syriacus n. sp. from Syria and T. mesopotamicus n. sp. from northern Irak, are described. The first instar larva of T. syriacus is described and compared with that of T. chrysocomus, both figured by scanning electron microscopy photographs.

Scanning electron microscopy documentation of all preimaginal stages of the lauxaniid species Minettia longipennis (Fabricius) is presented for the first time. Images of the following morphological structures of all larval instars are provided: pseudocephalon, antenna, maxillary palpus, facial mask, cirri, mouth hooks, ambulatory lobes, anterior and posterior spiracles. Illustrations of the cephalopharyngeal skeleton for all three instars in lateral, ventral and dorsal views are provided. All instars are clearly separable by morphological features. The first instar has unique modification of the facial mask and structure of the cephalopharyngeal skeleton. Second and third instars are similar in overall form and differ in details in structure of the mouthooks and anterior spiracles, and by the number of pharyngeal ridges.

The glochidium of Margaritifera auricularia is described for the first time by using light microscopy, scanning electron microscopy and histological techniques. The larval mantle is formed by only two layers of cells; the inner one being much thicker, with microvilli. All cell masses of the glochidium are temporary aggregations that are the rudiments of organs of the subsequent juveniles which will be released after metamorphosis in the host tissues. In the glochidium there are three main masses of cells: (i) the muscle, which is in an anterior position; (ii) the oral plate in the centre of the larva; and (iii) the more ventrally and posteriorly situated ventral plate, or foot rudiment, flanged with lateral pits all bearing dense cilia. No rudimentary organs such as the pericardium, the kidney, the heart or nerve ganglia have developed. There are no visible hooks in the valve margins, but by using light microscopy we observed minute teeth covered by a rim of the periostracum. Near the margin of the shell there are two pairs of sensory hair tufts only observable by scanning electron microscopy. The glochidium of M. auricularia is the largest of the family Margaritiferidae and intermediate between the glochidium of the known species of this family and those of Unionidae.
