AbstractDistribution patterns between continental and continental-island sister taxa are compared for some legume-feeding psyllids (Arytaininae, Psylloidea) and their host plants (Genisteae, Leguminosae). The host plant genera Adenocarpus, Chamaecytisus, Retama and Teline are characterized by distribution disjunctions, which sometimes match the disjunctions in the associated psyllids. Sister taxa pairs of Retama- and Teline-feeding psyllids from the continent and Macaronesian islands exhibit a similar geographic disjunction as their host plants, but this pattern is not found in Adenocarpus- or Chamaecytisus-feeding psyllids and their hosts. In addition, three closely related continental psyllids reflect the distribution of their Adenocarpus hosts in the montane regions of Morocco and Andalusia, but are not related to other Adenocarpus-feeding species. These examples suggest that among the Genisteae-feeding psyllids, shared distribution patterns with their hosts are localized rather than characteristic of the group as a whole. Six new species of psyllid, which feed on legume shrubs in the Genisteae, and are endemic to the Iberian Peninsula and Morocco, are described and illustrated. These species are in two taxonomically complex arytainine genera, Arytainilla and Livilla. Immature stages provide additional morphological characters useful for resolving taxonomic relationships within the Arytaininae, and the 5th instar nymphs of several species are described and illustrated. Genistoid-feeding psyllids are not known from all genera in the Genisteae but this may be due to incomplete sampling of rarer genistoid legumes. The majority of psyllids newly described here are narrow range endemics in either Andalusia or Morocco; one species occurs in both Andalusia and Morocco, and one species is more widespread in the Iberian Peninsula.

A New Species

Ripersiella emarai is described from Ficus cyathistipula Warburg, Ficus lyrata Warburg and Dieffenbachia sp. from Dutch greenhouses. The immature stages are described based on microscopic features and a key to the stages is provided for their separation. This species description is actuated by the necessity to distinguish the new species from the root mealybug Ripersiella hibisci (Kawai & Takagi), which is occasionally imported and shares host plants with the new species. An identification key to adults of the Dutch greenhouse species and species intercepted during import inspections based on microscopic morphological characters is given. A key to distinguish the nymphal stages is provided and keys are given to the identification of first, second and third instar nymphs of Ripersiella multiporifera Jansen, R. hibisci (Kawai & Takagi) and R. emarai Jansen. Rhizoecus advenoides Takagi & Kawai, 1971 is found to be a junior synonym of Rh. amorphophalli Betrem, 1940.

Two New Species

Two new species of the weevil genus Rhamphus from Italy are herein described: R. bavierai n. sp. (Sicily) and R. hampsicora n. sp. (Sardinia). Both are morphologically and from a molecular perspective close to R. oxyacanthae (Marsham, 1802) and R. monzinii Pesarini & Diotti, 2012. Aside from a diagnostic description and a synoptic key, distribution data and notes on the host plants of the four species are reported. Whereas R. monzinii can be distinguished by several morphological characters, the other three species are morphologically very similar to each other and separable only by the combination of a few subtle characters. On the contrary, a preliminary molecular study revealed substantial divergences of mtCOI from 6.2 to 14.9% between the species, confirming the importance of an integrative taxonomy.

Herein, we studied the occurrence of insect galls from natural vegetation around the Itambé Cave, Altinópolis, SP, Brazil. A sampling effort of 7.5 hours resulted in 41 gall morphotypes on 21 host plant species from 14 families. The richest families of host plants in morphotypes were Fabaceae (N = 11), Euphorbiaceae (N = 7), and Malpighiaceae (N = 5). Copaifera langsdorffii Desf. (N = 8), Croton floribundus Spreng. (N = 7), Diplopterys pubipetala (A. Juss.) W.R. Anderson & C.C. Davis (N = 5), and Bauhinia holophylla (Bong.) Steud. (N = 4) were the super host plant species. Among the gall makers obtained, cecidomyiids were reared in 81% of cases and Hemiptera (Diaspididae), Hymenoptera (Eurytomidae), Coleoptera (Apion sp./Apionidae), and Lepidoptera in 4.5% of cases, each. The parasitoids belong to the Chalcidoidea superfamily (Hymenoptera). One new species of Camptoneuromyiia (Cecidomyiidae) was found in Smilax oblongifolia Pohl ex Griseb. (Smilacaceae) as inquiline and a new species of Lestodiplosis in Diplopterys pubipetala (Malpighiaceae) was a predator. We also present the first register of Bauhinia holophylla as host plants of Cecidomyiidae, and we expand the occurrence of Rochadiplosis tibouchinae Tavares and Couridiplosis vena to São Paulo State. The results of this paper are a continuation of the description of gall morphotypes from the vegetation in Northeastern São Paulo State, and they also increase knowledge about the diversity of host plant and gall-maker associations in the Neotropical region.

Four new leaf mining Oecophyllembiinae (Gracillariidae) species are described from Chinaand Japan: Metriochroa sym-plocosella sp. nov. (host plants: Symplocos anomala, S. sumuntia, Symplocaceae) from China, Guttigera schefflerella sp. nov. (host plant: Schefflera octophylla, Araliaceae), Eumetriochroa araliella sp. nov. (host plants: Dendropanax trifidus, Evodiopanax innovans, Eleutherococcus sciadophylloides and Fatsia japonica, Araliaceae) and Corythoxestis tricalysiel-la sp. nov. (host plant: Tricalysia dubia, Rubiaceae) from Japan. Corythoxestis sunosei (Kumata, 1998) is recorded from new host plants: Adina pilulifera and Mussaenda parviflora, Rubiaceae, from Japan. The female adult and pupal morphol-ogies, life history and host plant of the genus Guttigera are described for the first time. Pupae of seven species of four genera: Corythoxestis, Eumetriochroa, Guttigera, and Metriochroa, are described for the first time. We provide morpho-logical diagnostic differences between species and genera of Oecophyllembiinae and Phyllocnistis. Our preliminary data suggest that Oecophyllembiinae species have three valuable pupal diagnostic characters: 1) cocoon cutter with unique lat-eral processes or setae on the clypeus, 2) tergal spines with only a pair of dorsal setae, and 3) cremaster with more than two pairs of caudal processes, while Phyllocnistis species possess 1) cocoon cutter without lateral processes or setae on clypeus, 2) tergal spines with a pair of dorsal setae and dorsal hooks, and 3) cremaster with only a pair of caudal processes.

A new endemic psyllid genus from the Hawaiian Islands, Stevekenia gen. nov., is described. Two new species, both single island endemics, feed on host plants in the endemic genus Nothocestrum (Solanaceae). Stevekenia nothocestri sp. nov. is found on Nothocestrum longifolium on the island of Oahu and Stevekenia aiea sp. nov. is found on N. peltatum on the island of Kauai. The host plants are montane rainforest species and both are on the IUCN Red List of Threatened Species. In particular, N. peltatum, which is endemic to the island of Kauai, is considered critically endangered, and therefore a similarly endangered status for these host-specific insects is likely. Only a few specimens of each Stevekenia species have been found, suggesting occurrence at low abundance. The host plants survive either as isolated individuals or small fragmented populations, which may already constitute less than the required critical host plant density for the long term survival of this psyllid genus. Unique morphological characters distinguish Stevekenia from other Hawaiian genera, and the placement of this genus within Triozidae is discussed. Mitochondrial DNA barcodes for the new species are provided.

Size And Shape

The clover, or brown, mite, Bryobia praetiosa Koch, was described in 1836 from specimens collected an shrubbery in Germany. The systematics of the species is complex and confusing. By 1838, Koch had described four species in the genus Bryobia but he preserved no type specimens and his descriptions do not agree with his illustrations (7, 12). Subsequent workers either placed Koch's species in synonomy nor described new species. Two species, speciosa Koch and ribis Thomas, have created the most controversv. B. speciosa was accepted as valid by Koch, Berlese, Canestrini and Fanzago, ind Oudemans, but rejected by von Hanstein and Trägårdh (2, 12). The gooseberry mite, B. ribis, was recognized as a valid species by Thomas and von Hanstein but Oudemans and Trägårdh placed it in synonomy with B. praetiosa (12). Further confusion was caused by the descriptions of additional new species of Bryobia and by descriptions of immature stages of B. praetiosa (8). The following taxonomic characters used by early acarologists in describing species of Bryobia have since been considered too variable for distinguishing species: number of femoral and tarsal hairs on the foreleg, body size, concavity of dorsum, and size and shape of cephalothoracic plate (7, 8, 12). Consequently, taxonomists have been at a loss to interpret Koch's original descriptions and subsequent redescriptions became inevitable. Because of the lack of morphological distinctions the modern trend has been to group all previously proposed species into one valid species (7, 8). As a result, 20 synonyms are now recognized for B. praetiosa (8).
