Morphology of the first instar nymph of Leucaspis loewi Colvée (Hemiptera: Coccinea: Diaspididae) The first instar nymph of Leucaspis loewi Colvée is redescribed and illustrated. The sex has not been determined. It has 5-segmented antennae, one trilocular disc pore associated with the anterior spiracle, one pair of well-developed lobes, and fimbriate plates on all abdominal segments. Tibia and tarsus are not fused - they are separated from each other by a septum. A campaniform sensillum is always present at the bases of the tarsi. Dorsal submedian setae are present on each abdominal segment 1-7.

<p><em>Stenocranus pacificus </em>Kirkaldy (Hemiptera: Delphacidae) is destructive pest on corn plants in South Lampung and it has been reported to cause corn damages in North Sumatra. The  objective of this research was to study some aspects biology of <em>S. pacificus</em> on corn plants in screenhouse. The research was conducted by observing the biology of <em>S. pacificus</em> that was reared on corn plants in screenhouse.<em> </em>The results showed that life cycle of <em>S. pacificus </em>was 38–47 (41,60 ± 3,19) days: egg was 9–11 (10,20 ± 0,79) days, the first instar nymph was 3–4 (3,70 ± 0,48) days, the second instar nymph was 3–4 (3,90 ± 0,32) days, the third instar nymph was 3–4 (3,70 ± 0,48) days, the fourth instar nymph was 3–4 (3,80 ± 0,42) days, and the fifth instar nymph was 3–4 (3,60 ± 0,52) days. Age of female was 13–17 (15,30 ± 1,34) days. It was longer than age of male which was 8–12 (10,10 ± 1,20) days. Female could produce 181–214 (197,60 ± 11,64) eggs during its life. The sex ratio was 1:1,98.</p>

The first-instar nymph and adult female of Kermes greeni Bodenheimer, 1931 are redescribed and a lectotype is designated. Kermes palestiniensis Balachowsky, 1953 is synonymized with K. greeni. This synonymy is based on a study of the type material of K. greeni and K. palestiniensis, as well as on fresh, topotypic material collected from Quercus calliprinos Webb in Israel.

New Pest

The adult female and first-instar nymph of a new species of soft scale insect, Hemilecanium mangiferae Kondo & Williams sp. nov., are described and illustrated. This species was collected on the trunk and branches of mango, Mangifera indica L., in Nakhon Pathom and Sukhothai Provinces, Thailand. The insect can cause serious damage by depleting the host sap and by producing large amounts of honeydew on which sooty molds grow. Damage was severe on the local mango cultivar, Nam DokMai. Also included are a revised diagnosis of the genus, a revised key to the adult females of the five species currently placed in the genus, and a key to the known firstinstar nymphs.La hembra adulta y la ninfa del primer estadio de una nueva especie de escama blanda, Hemilecanium mangiferae Kondo & Williams sp. nov., se describe e ilustra. Esta especie fue colectada en el tronco y ramas del mango: Mangifera indica L. en las provincias de Nakhon Pathom y Sukhothai, Tailandia. Este insecto puede causar daños severos al mango deprivando el árbol de savia, y produciendo gran cantidad de melado cual induce el crecimiento de fumaginas. El daño fue más severo en un cultivar local conocido como Nam Dokmai. Tambien se incluyen una diagnosis revisada para el género, una clave revisada para las hembras adultas de las cinco especies actualmente incluidas en el género, más una clave para las ninfas del primer estadio conocidas.

Two African soft scale insects, Toumeyella lomagundiae Hall and T. obunca De Lotto, are transferred to Hallicoccus gen. nov. The adult females of both species are redescribed, and the first-instar nymph of T. lomagundiae is described. A revised taxonomic key to separate the adult females is provided. The affinity of Hallicoccus gen. nov. with the genus Toumeyella Cockerell is briefly discussed.

A New Species

The gall-inducing genus Cissococcus Cockerell is revised to include two species. The family placement of Cissococcus has been uncertain, but characters of the first-instar nymph and adult male clearly show that Cissococcus is a soft scale insect (Coccidae) and is therefore the only member of the Coccidae known to induce a complex covering gall. All stages of the type species, C. fulleri Cockerell, are described and illustrated, plus the adult and third-instar female and first-instar nymph of a new, closely-related species, C. braini Hodgson & Millar sp. n. Both species are known only from wild vines in the southeast and C. fulleri also in the northeast of South Africa, but each induces a unique gall and each appears to be restricted to a different species of Rhoicissus (Vitaceae). The galls of each species are described and figured, and gall induction in the Coccidae is briefly discussed.

A New Species

A new species, Neogreenia lonicera Wu & Nan, is described and illustrated based on the adult female, second-instarfemale and first-instar nymph. This new species was collected at Helan Mountain, Inner Mongolia, China, in bark crevicesof Lonicera microphylla (Caprifoliaceae). A key is provided to separate the five species now known in NeogreeniaMacGillivray. A cladistic analysis of morphological data from adult females and first-instar nymphs of 28 archaeococcoidgenera has Neogreenia in a clade with Jansenus Foldi and Neosteingelia Morrison and usually also with KuwaniaCockerell, and thus Neogreenia should be placed in the family Kuwaniidae. A key to distinguish the adult females of the four genera of the Kuwaniidae is provided.
