The genus Konothrips was erected by Bhatti (1990) for a single species, tuttlei, that was described from Arizona in the genus Chirothrips by zur Strassen (1967). The new genus was distinguished by the longitudinally orientated sculpture on the abdominal terga and sterna, the fore wing costa with only a single seta, and the ovipositor lacking teeth (Bhatti 1990). Subsequently, Nakahara and Foottit (2012) described in Konothrips a second species, colei, from Texas. However, those authors indicated that there is variation in these characters, with  colei intermediate in structure between tuttlei and members of Arorathrips. In the new species described below, the abdominal tergal and sternal sculpture is weakly developed, transverse medially with some reticles in the pleurotergites slightly orientated longitudinally, the ovipositor is reduced and smooth, and costal setae are present on the fore wing. This new species is described in Konothrips because antennal segment I is enlarged (more than 3 times wider than base of segment II), antennal segment II is strongly produced laterally, and the mesosternal furcal invaginations are widely separated. These characters are also shared with the species of Arorathrips, and distinguish this pair of genera from Chirothrips. However, the new species, together with tuttlei and colei, is distinguished from species placed in Arorathrips by the presence of more than 6 stout conical setae on the median area of the mesonotum, and the anterior abdominal tergites with D1 and D2 setae spine-like (conical and stout).

Twelve species of jumping plant lice, Hemiptera: Psylloidea, in two genera are recognised from plants of the genus Allocasuarina (Casuarinaceae) in Australia. Aacanthocnema Tuthill & Taylor comprises two species that are here redescribed, Aa. casuarinae (Froggatt) and Aa. dobsoni (Froggatt), together with four new species, Aa. burckhardti Taylor, Aa. huegelianae Taylor, Aa. luehmannii Taylor, and Aa. torulosae Taylor. A new genus, Acanthocasuarina Taylor, comprises six new species: Ac. acutivalvis Taylor, Ac. campestris Taylor, Ac. diminutae Taylor, Ac. muellerianae Taylor, Ac. tasmanica Taylor, and Ac. verticillatae Taylor. Both genera are characterised by an elongate habitus, short Rs and short, triangular radial and cubital fore wing cells, ventrally produced genal processes beneath angular, overhanging apical margin of vertex, antennae short, and nymphs characteristically elongate, heavily sclerotised and scale-like. Species of Acanthocasuarina have rhinaria on antennal segments 4, 6, 8 and 9, the hind tibia has 1 outer and 2 inner spurs and the female proctiger has a posterior apical hook. In contrast, species of Aacanthocnema lack rhinaria on antennal segment 8 and sclerotised spurs on the hind tibia, and the female lacks a posterior apical hook on the proctiger. Trioza banksiae Froggatt stat. rev. is removed from Aacanthocnema. Keys to genera and species are provided, together with notes on their biology, host associations and biogeography.

Polyzoary (?) forming a simple, flattened, unbranehed, two-edged frond, with sub-parallel sides, consisting of two series of cells, the bases of which rest upon opposite sides of a thin longitudinally-striated central membrane or laminar axis, from which they pass obliquely outwards in opposite directions. The cells open in longitudinal rows on the two flat or slightly convex surfaces of the frond, and have the form of more or less cylindrical tubes, which are septate or are divided transversely by a series of well-developed tabulæ. In the only species known the cells of a few of the median rows of the frond are straight, but those of the lateral rows are oblique. Cell-mouths unknown.

Branchiura Sowerbyi

The genus Monopylephorus Levinsen, 1884 is revised, and divided into three genera. Monopylephorus includes rubroniveus, limosus, kermadecensis, parvus, irroratus, aucklandicus, and the new species cuticulatus and evertus. Rhizodrilus Smith, 1900 includes lacteus, africanus, pacificus, lowryi, and arthingtonae, the last two being transferred from Torodrilus Cook, 1970 and Rhyacodrilus Bretscher, 1901 respectively. Peristodrilus gen.nov. contains the single species montanus. Two other species (M. longisetosus and M. frigidus) will be referred to a new genus within the Phallodrilinae rather than the Rhyacodrilinae. The single member of the Branchiurinae, Branchiura sowerbyi Beddard, 1892 is related to both Rhizodrilus and Bothrioneurum Stolc, 1888 and is included with the Rhyacodrilinae. Telmatodrilus multiprostatus does not usually have its spermathecae in IX but in X as normal, and is not related to Rhizodrilus.The diffuse prostates in some Rhyacodrilinae may have groups of cells penetrating the muscle layers of the atria, somewhat resembling the clustered cells of the Telmatodrilinae, but with the cell bodies still forming a continuous atrial covering.The forward relocation of the spermathecae in Rhizodrilus and their absence in Bothrioneurum seems to be related to the development of large copulatory bursae in XI and the occupation of much of X by atria and vasa deferentia.

The new genus Altavelia Polhemus & Moreira (Heteroptera: Gerromorpha: Veliidae) includes seven species previously contained in the inveruglas group of Paravelia Breddin, 1898 and four new species from Colombia: A. altoandina Molano & Morales, A. antioquia Molano & Morales, A. montana Molano & Morales, and A. quindiana Molano & Morales. Additionally, A. amoena (Drake, 1957) is synonymized with A. flavomarginata (Hungerford, 1930). The genus is characterized by prominent setal tufts or sclerotized wing-like processes on the male proctiger; elongate body shape with long, slender legs; uniformly blackish forewings; antennal segment I longest; and the female abdomen with tergum VIII deflexed. Species in this genus occur at high elevations in the Andes Mountains with records from 1500 to 3600 m. A key is provided to all 11 species in the genus and new distributional records are presented for A. boliviana (Breddin, 1898), A. columbiensis (Hungerford, 1930), and A. flavomarginata.

Nomen Dubium

Kochaspids are an informal group of ptychopariid trilobites that were both abundant and widespread in the early Middle Cambrian of North America. Based on the reassociation of pygidia and cranidia of some kochaspids, Kochiella Poulsen, 1927, is redefined and Hadrocephalites n. gen. is proposed. Hadrocephalites includes taxa previously assigned by Rasetti and Palmer to Schistometopus Resser, 1938a. Schistometopus is considered nomen dubium. Representatives of Kochiella and Hadrocephalites from the Pioche Shale and Carrara Formation of Nevada are described, including the new species Kochiella rasettii, K. brevaspis, Hadrocephalites lyndonensis, and H. rhytidodes. Other kochaspids previously assigned to Kochaspis Resser, 1935; Eiffelaspis Chang, 1963; Schistometopus; and Kochiella are discussed and some are reassigned. The type specimens of Kochiella augusta (Walcott, 1886); K. crito (Walcott, 1917b); K. chares (Walcott, 1917a); K. mansfieldi Resser, 1939; K. arenosa Resser, 1939; Hadrocephalites carina (Walcott, 1917b), and H. cecinna (Walcott, 1917b) are re-illustrated.

A new genus, Casuarinicola Taylor gen. nov., comprising five new species of jumping plant lice (Hemiptera: Triozidae) from Casuarina s.s. (Casuarinaceae) from Australia and New Caledonia, is described. New species are: C. australis Taylor sp. nov., C. nigrimaculatus Taylor sp. nov., C. mucronalatus Taylor sp. nov., C. novacaledonica Taylor sp. nov. and C. warrigalensis Taylor sp. nov. The genus is characterised by the following combination of characters: antenna short, 1.1–1.5 times width of head, genal processes short, conical, 0.2–0.5 times length of vertex, fore wing with broadly rounded to subangular apex, mottled with dark markings (in females of most species) or clear (in males of most species), male proctiger short, with broad lateral expansions, parameres simple, and female proctiger short, broadly rounded, pointed apically and with a pair of broad, flange-shaped lateral lobes. A key to species is provided, together with notes on host associations and distribution.

Two New Species

A new genus and two new species of Sminthurinae are described. Keratosminthurus tapigu gen. nov. sp. nov. and K. calamitosus sp. nov. show a combination of features that redefines the subfamily Sminthurinae, such as a pair of sminthuroid chaetae, unguis without cavity, nine apical chaetae on tibiotarsus, 11 or more anterior dental chaetae, fourth antennal segment clearly subdivided into many (18 or more) subsegments, and asymmetric apex of mucro. The new genus also presents a striking sexual dimorphism, with modifications on male apical organ of antennal segment III, spines on the clypeus and special organs on the interocular area.

Two new genera and six new species of spore-feeding Thysanoptera are described from Australia, with Australian records of two further species, one from California and one from New Zealand. In the Tribe Pygothripini, subtribe Pygothripina, Ecacleistothrips glorious gen. et sp. n. is a large and highly polymorphic rainforest thrips: the apterous male has a transverse first abdominal tergite, in contrast to the females that have a reduced pelta as is typical of most Phlaeothripidae. Also in this subtribe, Heptathrips cumberi Mound & Walker from New Zealand is recorded widely around the southern coasts of Australia. A key is provided to the six genera of Pygothripini subtribe Allothripina in which the terminal sensorium of the maxillary palps is unusually large. In this group, four wingless species are considered: Minaeithrips aliceae gen. et sp. n. and M. driesseni sp.n. in which the maxillary stylets are wide apart, Allothrips hamideae sp. n. in which the third antennal segment has a basal flange unlike any other member of this widespread genus, and Priesneriella citricauda Hood that was previously known only from California. In the Pygothripini subtribe Macrothripina, Polytrichothrips geoffri sp. n. is described from rainforest; this genus was known previously from a single species in Sarawak. A further rainforest species, Malesiathrips australis sp.n., is described in the Tribe Idolothripini, subtribe Elaphrothripina; this genus was known previously from three species in the Asian and Pacific regions.

Iterative Evolution

The well-exposed and fossiliferous Permian carbonates in China have yielded Early and Late Permian species of the Sweetognathus complex that permit worldwide stratigraphic evaluation of members of the group. The sporadic appearance of species of Sweetognathus and related genera throughout the Permian in western North America and Iran, in particular, may represent iterative evolution and homeomorphy. The pectiniform element morphologies of the several species are interpreted as most important for evolutionary studies and document a partial Permian biostratigraphy in China that aids in the interpretation of less complete sequences elsewhere. A new genus, Pseudosweetognathus, and four new species, Pseudosweetognathus costatus, Sweetognathus subsymmetricus, S. paraguizhouensis, and Iranognathus nudus, are described.
