Number Of Segments

Ergasilus von Nordmann, 1832 is the type and the most speciose genus of Ergasilidae, with more than 150 valid species. The first species of this genus, Ergasilusiheringi Tidd, 1942, was described from the Neotropical Region, from the gills of Hopliasmalabaricus (Bloch, 1794). Since then, 35 new species of Ergasilidae have been described from the Neotropics. However, a reanalysis of the available type specimens of E.iheringi revealed features that suggest that it represents a lineage independent from Ergasilus. Consequently, we propose Tiddergasilus gen. nov. (Ergasilidae: Cyclopoida) to accommodate T.iheringi (Tidd, 1942) comb. nov. The species was re-examined and redescribed based on available type specimens. Tiddergasilus gen. nov. is characterized by species with exopod of leg 4 2-segmented; antenna small and robust, with a short second segment (approximately three times shorter than the first segment), and claw with a unique morphology (short, recurved with a sub-proximal indentation in the inner margin). A phylogenetic analysis, based on a matrix of 15 taxa and 16 morphological characters in PAUP* software 4.0a152, resulted in 15 equally parsimonious trees. Based on this analysis, Tiddergasilus is closely related to a group composed of Neotropical species of Ergasilus – sharing with them antennule with 6-segments. When the highly homoplastic character “number of segments in the antennule” is removed from the analysis, Tiddergasilus forms a polytomy with the clade of genera of the former Vaigamidae, Ergasilus, and the clade Rhinergasilus+Brasergasilus+Pindapixara.

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).

A New Species

Abstract We describe a new species of Crocidura (Soricidae) from Sulawesi Island, Indonesia, documenting its novelty with both genetic and morphological characters. The new species is widespread on the island, with vouchered records from nine general localities distributed among five of the island’s areas of endemism. Morphologically, the new species is readily distinguished from all other described Sulawesi Crocidura by its intermediate body size, gray pelage, and long, hairy tail. The new species was mainly captured in pitfalls placed in the ground, but we also obtained evidence that it readily climbs trees and may be scansorial in its locomotor habits. Populations of the new species sampled from across the island are closely related, separated by < 0.02 uncorrected mitochondrial p-distances. The new species is one member of an endemic radiation of shrews on Sulawesi now known to contain six valid species and several undescribed species, all within the genus Crocidura. Resolution of species limits and phylogenetic relationships in this radiation is hindered by habitat loss at type localities, historical designation of new species using very small sample sizes, and a lack of genetic data from type specimens. Kami mendeskripsikan spesies baru Crocidura (Soricidae) dari Pulau Sulawesi, Indonesia, sekaligus mendokumentasikan keunikan karakter secara genetik maupun morfologi dari spesies tersebut. Spesies baru ini tersebar luas di Pulau Sulawesi, diketahui berdasarkan spesimen yang berasal dari sembilan lokasi umum yang tersebar di lima kawasan endemik di pulau tersebut. Secara morfologi, spesies baru ini dapat dibedakan dari spesies Crocidura lainnya dari Sulawesi berdasarkan ukuran tubuh yang sedang, rambut tubuh berwarna abu-abu, dan ekor yang panjang dan berambut. Spesies baru ini sebagian besar diperoleh dari perangkap sumuran yang ditanam didalam tanah, selain itu kami juga mendapatkan bukti bahwa spesies ini mampu memanjat pohon dan kemungkinan memiliki perilaku sebagai pemanjat. Beberapa populasi spesies yang dikoleksi dari Sulawesi ini mempunyai kekerabatan yang dekat, hanya dipisahkan oleh jarak proporsi DNA mitokondria (tidak terkoreksi) sebesar < 0.02. Spesies baru ini merupakan salah satu anggota dari suatu kelompok radiasi endemik cecurut di Sulawesi yang sampai saat ini diketahui terdiri atas enam spesies yang valid, dan beberapa spesies yang belum dideskripsikan, semuanya termasuk didalam genus Crocidura. Kepastian dalam menetapkan batasan jarak antar spesies dan hubungan kekerabatan genetik dari radiasi kelompok cecurut di Sulawesi terkendala oleh kerusakan habitat pada lokasi spesimen tipe, sejarah penamaan spesies yang hanya berdasarkan sampel yang sedikit, dan keterbatasan data molekuler dari spesimen tipe.

The genus Episcepsis Butler, 1877 is widely distributed in the Neotropical region and currently includes 43 valid species many of them described solely based on external morphology. The existence of species complexes makes their identification difficult without examination of genital morphology. Four new species from Brazil, Cuba and Peru are described herein; Episcepsis andina sp. nov., E. diversa sp. nov., E. insularis sp. nov. and E. travassosi sp. nov. Comparisons with other similar species as well as photographs of external morphology and male genitalia are provided.

Two New Species

A complete revision of the world species of the genus Phaenoglyphis Förster, 1869 has been conducted. A total of 25 species of Phaenoglyphis are valid after studying their type material. Two new species are described: Phaenoglyphis belizini sp. n. and Phaenoglyphis palmirae sp. n. Two species are synonymized: P. dolichocera (Cameron, 1889) with P. nigripes (Thomson, 1877) and P. pecki Andrews, 1978 with P. villosa (Hartig, 1841). Phaenoglyphis bangalorensis Kurian, 1953 was considered as incertae sedis. Phaenoglyphis duplocarpentieri (Kieffer, 1904) and P. hedickei Hedicke, 1928 are considered lost. Other three species are discarded as valid species because they are missing important parts without which the species cannot be defined: P. cincta (Hartig, 1841), P. frigidus (Belizin, 1968) and P. repentinus Belizin, 1962. A complete redescription and an illustrative plate are presented. A key to species of the genus Phaenoglyphis is given. Phylogenetic analysis based on morphological characters has been performed.

Neotropical Species

The identity of many Neotropical species of Pseudisobrachium Kieffer, 1904 is currently unreachable, mostly because the available descriptions and illustrations are not sufficiently accurate to allow precise identifications. To help solve the problem, 115 valid species and their junior synonyms were examined. Twelve nomenclatural acts are made, and 110 valid species are recognized for the Neotropical region. Two lectotypes are designated: Pristocera crassicornis Westwood and Pristocera haemorrhoidalis Westwood. Seven new species-group synonyms are proposed: Pseudisobrachium retusum Evans syn. nov. for P. pauxillum Evans; P. cunco Perez syn. nov. for P. erythrocephalum Evans; P. navajo Evans, P. rectangulatum Evans, P. emarginatum Evans and P. foutsi Evans syn. nov. for P. flavinervis Fouts; P. acuminatum Waichert & Azevedo syn. nov. for P. latum Waichert & Azevedo. The following new genus-group synonym is established: Parisobrachium Kieffer syn. nov. for Dissomphalus Ashmead. The following new combination and reinstated name are proposed: Dissomphalus albipes (Kieffer) comb. nov. and nom. rev. from Pseudisobrachium paraguayense Kieffer.

The world fauna of the genus Leptomorphus Curtis, 1831 is revised and a phylogeny of species relationships, based onmorphological characters, is presented. An updated genus diagnosis and description are given. Species descriptions,diagnoses, illustrations of general habitus, wings, male genitalia and distributions are provided for 37 valid species, alongwith a key to adults.Twelve new species are described; L. amorimi Borkent, n. sp., L. brandiae Borkent, n. sp., L. crassipilus Borkent, n.sp., L. eberhardi Borkent, n. sp., and L. waodani Borkent, n. sp., from the Neotropical realm, L. furcatus Borkent, n. sp.,and L. perplexus Borkent, n. sp., from the Nearctic realm, L. mandelai Borkent, n. sp., and L. stigmatus Borkent, n. sp.,from the Afrotropical realm, and L. tabatius Borkent, n. sp., L. tagbanua Borkent, n. sp., and L. titiwangsensis Borkent,n. sp., from the Oriental realm. Type specimens were studied for all but three species (L. ornatus, L. subforcipatus and L.talyshensis). Leptomorphus elegans Matile and L. lepidus Matile are considered junior synonyms of L. gracilis Matile, n.syns., and L. ypsilon Johannsen is a junior synonym of L. hyalinus Coquillett, n. syn. Lectotypes are designated for L.magnificus (Johannsen), L. neivai Edwards, and L. walkeri Curtis and a neotype is selected for L. bifasciatus (Say). Thisstudy brings the total number of extant Leptomorphus species to 45, including eight, unique (based on figures anddescriptions), recently described Oriental and northwestern Australasian species (Papp & Ševčík 2011), for whichmaterial was unavailable for this study. The phylogenetic analysis in this study supports the monophyly ofLeptomorphus. The western Nearctic species, L. perplexus, is the sister group to the remaining species, which fell intofour major monophyletic species groups (L. ornatus Brunetti group, L. grjebinei Matile group, L. walkeri group, L.furcatus group). The monophyletic relationships within each group are also discussed. The clades found in this study do not support the arrangement of species in to the Leptomorphus subgenera recognized by previous classifications.

Parsimony Analysis

The species of the former antlion subtribe Periclystina (Neuroptera: Myrmeleontidae) are revised. Prior to this work Periclystina comprised 10 genera and 63 species endemic to Australia (62 spp.) and New Guinea (1 sp.). In this work two former genera are synonymized and four new genera are proposed (for a total of 12 valid genera), and six former species are synonymized and 16 new species are proposed (for a total of 73 valid species). A parsimony analysis utilizing 62 morphological characters is used to infer phylogenetic relationships among all 73 species, and suitable outgroups. Based on the results of the phylogenetic analysis, the tribal and/or generic assignments of 55 (75%) of former Periclystina species are modified here. Periclystina and its two largest genera—Austrogymnocnemia and Glenoleon—were all recovered as polyphyletic in their former circumscriptions. Ten species—placed here in six genera: Anomaloplectron, Csiroleon, Fissuleon gen. nov., Franzenia, Fusoleon and Latileon gen. nov.—clustered phylogenetically with Acanthoplectron and are transferred to the tribe Acanthoplectrini. The remaining 63 species—placed in six additional genera: Austrogymnocnemia, Glenoleon, Megagonoleon gen. nov., Minyleon gen. nov., Periclystus and Riekoleon—form a monophyletic Periclystus genus group and are transferred to the tribe Dendroleontini. All 73 species are (re)described and illustrated. New identification keys are provided for the tribes of Dendroleontinae, for the Australian genera of Acanthoplectrini and Dendroleontini, and for each of the non-monotypic genera treated. In addition, five new lectotypes are designated and 35 new combinations are created.

The described Neotropical species of the common and speciose fairyfly genus Gonatocerus Nees ab Esenbeck (Hymenoptera: Mymaridae) are reviewed and re-diagnosed. Eighty-four valid species are recognized including 11 newly described ones. Illustrated identification keys are provided to identify the 5 subgenera recognized in Gonatocerus and to females of each subgenus. The keys include 79 of the treated species, the other five species are known from males only. The known distribution ranges of the species, including new records of extralimital specimens examined, are given. Host associations of the treated species are also given, with emphasis on those species that parasitize eggs of proconiine sharpshooters (Hemiptera: Cicadellidae: Cicadellinae: Proconiini), all of which belong to the ater and morrilli subgroups of the ater species group of G. (Cosmocomoidea Howard), stat. rev. The other four recognized subgenera within Gonatocerus are the nominate subgenus, G. (Gonatocerus) (= sulphuripes species group of authors), G. (Lymaenon Walker), stat. rev. (= litoralis and straeleni species groups of authors), G. (Gastrogonatocerus Ogloblin), stat. rev. (= membraciphagus species group of authors), and G. (Gahanopsis Ogloblin), syn. n. & stat. n. (= deficiens species group of authors). Newly treated as synonyms of G. (Lymaenon) are Rachistus Foerster, Oophilus Enock, Agonatocerus Girault, Gonatoceroides Girault, and Decarthrius Debauche, all syn. n. Two species groups are recognized within G. (Cosmocomoidea) in the New World: the ater group, to which most Neotropical species belong (with the ater, bucculentus, morrilli, and the newly defined chusqueicolus subgroups) and the masneri group, with two described species from the Dominican Republic. The 11 new species described are G. (Gahanopsis) arkadak Triapitsyn sp. n. (Colombia), G. (Cosmocomoidea) barbos Triapitsyn sp. n. (Costa Rica and Mexico), G. (Cosmocomoidea) blefuscu Triapitsyn sp. n. (Costa Rica), G. (Cosmocomoidea) cuscus Triapitsyn sp. n. (Peru), G. (Cosmocomoidea) garchamp Triapitsyn sp. n. (Argentina), G. (Cos- mocomoidea) gerasim Triapitsyn sp. n. (Mexico), G. (Cosmocomoidea) hispaniolus Triapitsyn & Huber sp. n. (Dominican Republic), G. (Cosmocomoidea) kiskis Triapitsyn sp. n. (Argentina), G. (Cosmocomoidea) logarzoi Triapitsyn sp. n. (Argentina), G. (Cosmocomoidea) mumu Triapitsyn sp. n. (Argentina), and G. (Cosmocomoidea) rakitovi Triapitsyn sp. n. (Costa Rica). Seven new synonymies are proposed: Gonatocerus h-luteum (Ogloblin) syn. n. under G. (Cosmoco- moidea) nigriflagellum (Girault); G. enicmophilus Huber syn. n. and G. necator (Ogloblin) syn. n. under G. (Cosmoco- moidea) bonariensis (Brèthes); G. dimorphus (Ogloblin) syn. n. and G. monrosi (Ogloblin) syn. n. under G. (Gastrogonatocerus) margiscutum Girault; and G. setulosus (Ogloblin) syn. n. and G. dorsiniger (Ogloblin) syn. n. under G. (Gastrogonatocerus) membraciphagus Ogloblin. Litus maculipennis Ashmead, Gahanopsis deficiens (Ogloblin), and Gahanopsis straeleni (Debauche) are transferred to Gonatocerus as, respectively, G. (Cosmocomoidea) maculipennis (Ashmead) comb. n., G. (Gahanopsis) deficiens (Ogloblin) comb. n., and G. (Lymaenon) straeleni (Debauche) comb. n. Lectotypes are designated for the following 23 species: G. (Gahanopsis) acanophorae (Ogloblin), G. (Gahanopsis) aethalionis (Ogloblin), G. (Cosmocomoidea) annulicornis (Ogloblin), G. (Gastrogonatocerus) anomocerus Crawford, G. (Gonatocerus) appendiculatus (Ogloblin), G. (Gonatocerus) bonaerensis (Ogloblin), G. (Cosmocomoidea) caudatus (Ogloblin), G.

A New Species

Sibaria Stål is a genus of Pentatomidae occurring exclusively in the Neotropical region. Since its description, little information has been added to the knowledge of the taxon. The hypothesis of monophyly of Sibaria was recently supported by a phylogenetic analysis based on morphological and molecular data. The purpose of this study is to provide a review of Sibaria, redescribe the valid species, and describe a new species. The genus includes four species: S. andicola Breddin, S. armata (Dallas), S. englemani Rolston, and S. amazonica sp. nov.. Diagnoses, macrophotographs (habitus, external and internal genitalia), an identification key, and distribution records of the species are also provided.
