A revised pomi species group is proposed, with Typhlodromus pomi (Parrott, Hodgkiss &Shoene) as the exemplar. The group is characterized by the presence of seta R1 on the opisthoscutum of adult females and it is composed of 16 species, including 2 new species: Typhlodromus bromus (Denmark) comb, nov., T. eiko E1 Banhawy, T. flumenis Chant, T. herbertae Nesbitt, T. juniperi De Leon, T. juniperoides (De Leon) comb. nov., T. lindquisti n. sp., T. mexicanus (Muma) comb. nov., T. negundinis (Denmark) comb, nov., T. nelsoni Chant, T. pomi (Parrott, Hodgkiss &Shoene), T. pomoides Schuster and Pritchard, T. tuttlei (Denmark) comb, nov., T. validus Chant, T. paraflumenis n. sp., and T. pedoni Zaher and Shehata. Typhlodromus pomoides is reinstated as separate from T. herbertae, and Galendromus deleoni Tuttle and Muma is designated as a junior synonym of T. juniperi. Various generic concepts relating to the species in the pomi group are reviewed, the group is described, and a key to adult females and descriptions of each species are provided.

The revised tiliarum species group in the genus Typhlodromus Scheuten is defined by the presence of setae Z1, S2, S4, and S5 as well as J2, J5, Z4, and Z5 on the opisthoscutum, excluding sublateral seta R1 which may or may not be inserted on the opisthoscutum. The chaetotaxy on the opisthoscutum of the revised tiliarum group is identical with that of the australicus (in part) and simplex groups. However, the tiliarum group is distinguished from the former by the absence of seta z6 on the podoscutum and from the latter by differences in the nature of the peritreme and of the setae on the dorsal shield and by the shape of the ventrianal shield. The original tiliarum group included only 3 species whereas the revised group comprises 26 species, including one new species: T. comptus Corpuz, Typhlodromus crassipilis (Athias-Henriot and Fauvel) comb, nov., T. aceri Collyer, T. tuberculatus Wainstein, Typhlodromus runiacus (Kolodochka) comb, nov., T. transitans Gupta, T. tiliarum Oudemans, T. perforatus Athias-Henriot, Typhlodromus carmeli (Rivnay and Swirski) comb, nov., Typhlodromus montforti (Rivnay and Swirski) comb. nov., T. elisae Schicha and McMurtry, T. spaini Collyer, T. cassiniae Collyer, T. steveni Schicha, T. myopori Collyer, T. steeli Schicha and McMurtry, T. cottieri Collyer, T. dachanti Collyer, T. novaezealandiae Collyer, T. manukae Collyer, T. glenfieldensis Schicha, T. oleariae Collyer, T. corrugatus Schicha, Typhlodromus ashleyae sp.nov., T. armidalensis Schicha and Elshafie, and T. nesbitti Womersley. Heteroseiulus aceris Lehman is synonymized with T. aceri, Typhloctonus prunus Denmark and Rather with T. transitans, and Seiulus sexapori Karg and Edland with T. tuberculatus. Shiehia multispinosa Tseng and Typhloctonus vollsella Chaudhri are proposed provisionally as junior synonyms of T. comptus and T. transitans, respectively. Four genera, Neoseiulella Muma, Typhloctonus Muma, Pegodromus Athias-Henriot and Fauvel, and Heteroseiulus Lehman are designated as new junior synonyms of the genus Typhlodromus and one genus, Shiehia Tseng, as a provisional junior synonym. Most species in this group are recorded from temperate climates; 16 of the 26 recorded species are limited to the Australian faunal region. Various generic concepts relating to the species in the tiliarum group are reviewed and the general characters of the group are described. A key, descriptions, and illustrations for adult females of each species are provided.

In this paper, M. yanomami n. sp., from Brazilian Amazonia, Chaetacis bandeirante n. sp., from Central Brazil, and the males of M. gaujoni Simon, 1897 and M. ruschii (Mello-Leitão, 1945) n. comb. , respectively from Ecuador and Brazil, are described and illustrated for the first time. An ontogenetic series of the last development stages of both sexes of Micrathena excavata (C. L. Koch, 1836) is illustrated and briefly described. Adult females are larger and have longer legs and larger abdomens than adult males. Probably females undergo at least one additional moult before adulthood, compared to males. Micrathena ornata Mello-Leitão, 1932 is considered a junior synonym of M. plana (C. L. Koch, 1836), and M. mastonota Mello-Leitão 1940 is synonymized with M. horrida (Taczanowski, 1873). Acrosoma ruschii Mello-Leitão, 1945 is revalidated, transferred to Micrathena and considered a senior synonym of M. cicuta Gonzaga & Santos, 2004. Chaetacis necopinata (Chickering, 1960) is recorded for Brazil for the first time. Chaetacis incisa (Walckenaer, 1841) is considered a nomen dubium.

AbstractThe genus Kiransus Makhan, 1994 erected for a hydrochid species, K. aschnaae Makhan, 1994, with a unique and extremely modified tergum 8 (= 'sternum 5' of Makhan), is placed as a junior synonym (syn. n.) of Hydrochus Leach, 1817, in which it represents a highly derived, subordinate clade, here referred to as the 'Hydrochus aschnaae species group'. A redefinition of this clade is proposed, based on the discovery of three new species, Hydrochus tuberculatus sp. n. from Burkina, H. nigeriensis sp. n. from Nigeria and H. ensifer sp. n. from Sudan. Structural peculiarities in the abdominal apex of Hydrochidae are outlined and attention is called to certain features of phylogenetic importance.

The species belonging to the Monolepta pallidula species group are revised. Two species are recognized as valid: Monolepta sauteri Chûjô and M. kuroheri Kimoto. Taiwanese populations of Monolepta pallidula (Baly) are a distinct species different from the true M. pallidula. Thus Monolepta gracilipes Chûjô, a junior synonym of M. pallidula from Taiwan, is an available name and should be reinstated. A new species, Monolepta tsoui, is described with delimitation of color variation from its allied species, M. gracilipes. A lectotype is designated for Monolepta gracilipes Chûjô. A key to the species of the species group is provided.

The simplex species group is described on a worldwide basis. There are six species in the group as presently conceived, including a new species: Typhlodromus arzakanicus (Arutunjan), T. calabriae (Ragusa &Swirski), T. carmonae n. sp., T. peculiaris Kolodochka, T. simplex (Chant), and T. subsimplex (Arutunjan). A brief introduction to the various generic concepts of different authors is given in relation to the species which belong to the simplex group, and the basic characters of the group are outlined. A key to adult females is provided and morphological descriptions of the six species are given. Descriptions of the three species which we were unable to examine are based on the original descriptions and illustrations.

The present study represents a taxonomic revision of the Pheidole sikorae species group from Madagascar. Forty-four members of this group are recognised and described, and an illustrated identification key to this group is also presented. One species is raised to species level: P. litigiosa Forel, 1892 stat. nov.Pheidole veteratrix angustinoda Forel, 1892 syn. nov. is proposed as a junior synonym of Pheidole veteratrix Forel, 1891. Worker castes are also described and lectotypes designated for P. litigiosa Forel, 1892, P. sikorae Forel, 1891, and P. veteratrix Forel, 1891. The following 41 new species are described: P. alinasp. nov., P. ambohimangasp. nov., P. analavelonasp. nov., P. andohahelasp. nov., P. anomalasp. nov., P. anosyennesp. nov., P. antranohofasp. nov., P. beankasp. nov., P. befotakasp. nov., P. dasossp. nov., P. flavominutasp. nov., P. gracilissp. nov., P. habokasp. nov., P. havoanasp. nov., P. hazosp. nov., P. itremosp. nov., P. joffrevillesp. nov., P. kelysp. nov., P. lavasoasp. nov., P. mahamavosp. nov., P. maintysp. nov., P. mamiratrasp. nov., P. mananteninasp. nov., P. masoandrosp. nov., P. mavohavoanasp. nov., P. midongysp. nov., P. mikrossp. nov., P. mivorysp. nov., P. nitidobrunasp. nov., P. parvulasp. nov., P. parvulogibbasp. nov., P. reniranosp. nov., P. savasp. nov., P. sofiasp. nov., P. sparsasp. nov., P. tamponysp. nov., P. trichotossp. nov., P. tsaravonianasp. nov., P. vadumsp. nov., P. volontanysp. nov., and P. vonysp. nov. At present, there are 109 valid species and subspecies of Pheidole known from Madagascar, but this number is expected to increase with upcoming taxonomic revisions of the species groups not revised in this study.

A new species, Phytoseius feresi Demite & Cavalcante sp. nov. (Acari: Mesostigmata: Phytoseiidae) is described and illustrated based on adult females. It was found in association with plants in natural vegetation in Itacoatiara, Amazonas state, Brazil. This new species is a member of the purseglovei species group and differs of all other species of this group by possessing all dorsal setae, except Z5, and the ventral seta JV5 smooth. We propose a redefinition of purseglovei species group in order to include the new species. In addition, a key to world species of purseglovei species group is provided.

Three new species of the genus Aemene Walker, 1854 are described: Aemene cernyi sp. n. (NE India and E Nepal), Aemene laszloi sp. n. (C Nepal) and Aemene bucseki sp. n. (C Nepal and Pakistan). The Aemene taprobanis Walker, 1854 species-group is established and characterised. The status of one taxon previously considered as a junior synonym of A. taprobanis is revised: Aemene sinuata Moore, 1878, stat. rev. A taxon previously considered as a subspecies of A. taprobanis is upgraded to species level: Aemene likiangensis (Daniel, 1951), stat. nov. Lectotypes are designated for Aemene taprobanis Walker, 1854, Panassa cingalesa Walker, 1865, Autoceras grammophora Felder, 1874 and Aemene sinuata Moore, 1878. Adults together with the male and the female genitalia of the new and related species are illustrated.

Species of eight species-groups (seven named and one unnamed) of Simulium (Simulium) Latreille are revised chiefly based on the adult female and male genitalia. Four species-groups are each divided into more than two groups. Thus, the S. christophersi species-group is divided into two (S. christophersi and S. nebulicola species-groups), the S. griseifrons species-group into six (S. griseifrons, S. grossifilum, S. chungi, S. crocinum, S. indicum and S. yadongense species-groups), the S. malyschevi species-group into two (S. malyschevi and S. pavlovskii species-groups), and the S. melanopus species-group into three (S. melanopus, S. dumogaense and S. iridescens species-groups). The S. crassifilum species-group is merged with the S. variegatum species-group. Simulium fulvipes (Ono) of the former S. malyschevi species-group and S. dentastylum Yang, Chen & Luo of Simulium s. str. species unplaced to species-group are removed from the subgenus Simulium because their male styles are subequal in length to the coxites. A revised classification of species of the 15 species-groups including eight new species-groups of Simulium (Simulium) is presented. Keys to 20 species-groups of Simulium (Simulium) in the Oriental Region are provided for adult females and males.
