COURI, MARCIA S., ADRIAN C. PONT, and CHRISTOPHE DAUGERON. "The Muscidae (Diptera) of New Caledonia." Zootaxa 2503, no. 1 (2010): 1. http://dx.doi.org/10.11646/zootaxa.2503.1.1.

Full text

Abstract:

The Muscidae of New Caledonia are reviewed. A key for the identification of genera and species is given, together with diagnoses, descriptions and illustrations. The revision is based on literature records and on examined material from New Caledonia deposited in various museums and institutions. A total of 18 genera and 40 species are recognised, 7 of which are endemic and 4 of which are newly described: Dichaetomyia shinonagai, sp. nov.; Helina flavoextrema, sp. nov.; Limnophora longiantennata, sp. nov. and Pygophora spinifera, sp. nov. Helina Robineau-Desvoidy, Synthesiomyia Brauer & Bergenstamm and Neomyia Walker are newly recorded genera, and Atherigona bidens Hennig, Atherigona poecilopoda Bezzi, Lispe fuscipalpis Malloch, Lispocephala occulta (Pont), Musca ventrosa Wiedemann, Musca vetustissima Walker, Neomyia timorensis (Robineau-Desvoidy), Pygophora hopkinsi Malloch and Synthesiomyia nudiseta (Wulp) are newly recorded species for New Caledonia. Four species previously recorded in the literature on New Caledonia, Muscina stabulans (Fallén), Lispe assimilis Wiedemann, Pygophora maculigera (Stein) and Pygophora minuta Malloch, were not represented in the material examined. The male terminalia of the Atherigona species, Pygophora caledonica (Bigot) and the new species are illustrated. Coenosia pumilio Stein is redescribed. Lispe binotata Becker, 1914 is a new junior subjective synonym of Lispe nicobarensis Schiner, 1868, syn. nov. A brief discussion on the composition of the fauna is also given.

Abstract:

Japanese species of the genus Pygophora Schiner, 1868 are reviewed, with redescription of the following species: P. boninensis Snyder, 1965; P. confusa, 1915; P. immaculipennis Frey, 1917; P. lepidofera (Stein, 1915); P. longicornis (Stein, 1918); P. macularis (Wiedemann, 1830); P. maculipennis Stein, 1909; P. respondens (Walker, 1859); P. unicolor (Stein, 1920). New occurrence records are presented to P. macularis (Wiedemann, 1830), P. respondens (Walker, 1859), and P. unicolor (Stein, 1920). Pygophora trimaculata Karl, 1935 is excluded from Japanese species, as it had been based on a misidentification. The male and female terminalia are illustrated, and an identification key to the Japanese species is provided.

A new species of a tessaratomid bug, namely Pycanum occidentale sp. nov, is described with comments on the other species of the genus found in India. This species can be easily distinguished from the other species of Pycanum by the shape of male genitalia, especially pygophore and parameres. This becomes the fourth species of Pycanum in India and the first one from western India. A key to the extant species of the genus is also provided along with diagnostic images of pygophores and parameres for three species found in India.

Amemboa ripiaria Polhemus & Andersen, 1984 was recognised as junior synonym of Amemboa lyra (Paiva, 1918) byZettel & Chen (1996). After examination of a series of Amemboa specimens from Myanmar, we now determine that thesetwo names are not synonymous and thus re-establish Amemboa riparia. These species can be separated from each other by the structures of the male’s fore leg, and the apical part of the pygophore.

The genus Callostethus was described for Mecistorhinus guttatopunctatus (Fabricius, 1803). Here we describe a second species of the genus, C. flavolineatus sp. nov., based on a male collected in Amapá, Brazil. Descriptions were made using external morphological characters. Callostethus is closely allied to Antiteuchus and can be separated from it by the mesosternum slightly tumid with a low median subcalloused carina, calloused yellow or reddish margin of the metapleuron, and the structure of the pygophore.

Zootaxa 5240, no. 1 (2023): 1–63. http://dx.doi.org/10.11646/zootaxa.5240.1.1.

Full text

Abstract:

The subgenus Edessa, the largest and to date the most confusing taxon of Edessa is diagnosed here, comprising 79 species listed in this work. The subgenus is characterized by the humeral angles conical, somewhat developed, and projected, with apex rounded or somewhat acuminated, but never acute, shyny and impunctate or with a few punctures. The E. sexdens group, composed of 22 species, is proposed here to the subgenus Edessa. This group can be characterized by the anterior arms of the metasternal process with excavated apex; connexival segments with a pair of dark spots; ventral side of the abdomen raised medially; rounded shallow excavation near each spiracle; area between dorsal rim of the pygophore and posterolateral angles grooved; superior process of the genital cup laminar and continued ventrally by a carina, oblique to the parameres; parameres with three lobes; area between dorsal rim of the pygophore and posterolateral angles grooved. The species of the E. sexdens group are distributed in the Neotropical region, from Mexico to Argentina. Descriptions, measurements, and illustrations are provided. An identification key and distributional map are presented. The species Edessa suturata Dallas, 1851 is considered junior synonym of E. alces Erichson, 1848; E. inclyta Walker, 1868, E. fuscidorsata Distant, 1881, and E. gnu Breddin, 1905 are considered junior synonyms of E. electa Walker, 1868; E. olivacea Stål, 1862 and E. ventralis Walker, 1868 are considered junior synonym of E. phoenicopus Dallas, 1851; E. nigromarginata Distant, 1881 is considered junior synonym of E. sexdens Fabricius, 1803; E. subandina Breddin, 1994 is considered a valid species; Edessa dentata (Dallas, 1851) and Edessa excellens (Walker, 1868) are considered junior synonym of E. (E.) urus Erichson, 1848.

A new species of Cosmoclopius Stål, 1866, C. joceliae sp. nov. is described based on specimens collected in northern Argentina. This new species is recognized by the vertical and truncate median process of pygophore, and the short-recurved spine on the apex of the dorsal phallothecal sclerite; and other features such as the dorsally black head, pronotum, and femora, and the thoracic sterna black with median pale markings; some females show lighter posterior pronotal lobe and femora with more conspicuous dark and pale bands. Digital images of the adult male and female and male genitalia are provided, as well as a comparison with the species of the genus are given.

Abstract:

The pentatomid genus Piezodorus presently contains about 12 species, all of which, with one exception [i.e., P. guildinii (Westwood)], have been reported from the Old World; P. guildinii apparently is limited to the New World. P. guildinii and P. hybneri (Gmelin) are similar in appearance and have been considered by some as sister species. The following characteristics we consider valid as diagnostic to separate the two species: for males, the shape and length of the vesica, differences in the anatomy of the conjunctival appendages and penial plate, and shape of the pygophore and parameres; and for females, differences in the anatomy of the first and second gonocoxae, ninth paratergites, and spermathecae.

Abstract:

The male genitalia, including the pygophore, parameres, and inflated aedeagus, and the female terminalia, are compared between Mecidea major Sailer and M. minor Ruckes (Hemiptera: Pentatomidae). These structures are markedly different between these species, particularly the inflated aedeagus. In M. major, the penial lobes tof the aedeagus diverge in the basal 1/3, converge distally, with each lobe subquadrate apically. In M. minor, the penial lobes diverge midway to the apex, weakly converge distally, with each lobe rounded apically. We suggest the same 3 structures should be examined in the remaining 15 species of Mecidea to determine if the taxonomic status of each of these species is supported by the results.

Abstract:

Hypoxys is one of four subgenera of Edessa (Fabricius, 1787) together with Aceratodes (De Geer, 1773), Dorypleura (Lepeletier & Serville, 1825) and Edessa (Fabricius, 1787). This taxon has a very confusing taxonomy due to incorrect use of the names available, imprecise descriptions, and large number of very similar species. To illustrate the confusion, Hypoxys potentially includes a large number of species of Edessa, but actually contains only the type species, according to the most recent catalogue. The name E. quadridens Fabricius, 1803, type species of Hypoxys, was used for more than a century as a label to identify a large group of similar species. In this work we continue revising Edessa elevating Hypoxys to genus based on the following morphological characters: proximal part of costal margin black; evaporatorium with a deep notch on lateral margin; anterior arms of metasternal process acuminate; pygophore longer than wide and subrectangular or barrel-shaped in dorsal view; dorsal rim of pygophore well-projected, almost reaching posterolateral angles and finishing in a small lobe; and posterolateral angles of pygophore not developed. Hypoxys is being divided in four species groups to include 17 species transferred from Edessa. H. quadridens group comprises: Hypoxys quadridens (Fabricius, 1803) (type species), H. boerneri (Breddin, 1904) comb. nov., H. claricolor (Breddin, 1907) comb. nov., H. dolosus (Breddin, 1907) comb. nov., H. eburatulus (Breddin, 1907) comb. nov., H. necopinatus (Breddin, 1907) comb. nov., H. offuscatus (Breddin, 1907) comb. nov. and H. trabeculus (Breddin, 1907) comb. nov. H. triangularis group comprises: H. triangularis (Dallas, 1851) comb. nov. (type species), H. capito (Breddin, 1904) comb. nov. and H. subrastratus (Bergroth, 1891) comb. nov. H. oxyacanthus group comprises: H. oxyacanthus (Breddin, 1904) comb. nov. (type species), H. brachyacanthus (Breddin, 1904) comb. nov., H. infulatus (Breddin, 1904) comb. nov., H. leptacanthus (Breddin, 1904) comb. nov. and H. tragelaphus (Breddin, 1903) comb. nov. H. balteatus group comprises only H. balteatus (Walker, 1868) comb. nov. These groups of species will be useful to organize the new species of Hypoxys that will be described in upcoming papers. Descriptions, measurements, photos of genitalia of both sexes; photos in dorsal and ventral views of the species; and distribution maps are provided. Males of H. capito, H. claricolor, H. eburatulus, H. infulatus, and H. subrastratus are described for the first time. Female of H. necopinatus is described for the first time. Edessa jugalis is considered a junior synonym of H. quadridens; E. rimata a junior synonym of H. offuscatus; E. scabriventris and E. leprosula junior synonyms of H. triangularis; E. pachyacantha a junior synonym of H. tragelaphus; E. orba a junior synonym of E. oxyacanthus. A key to the species of Hypoxys is also provided.

Abstract:

ABSTRACT. Carpocoris pudicus Poda (1761) are small sized stink bugs belonging to order Heteroptera. (Carpocorini). The species first time collected in Hyderabad Sindh during 2015. The Carpocoris Pudicus causes a remarkable loss to different crops and weed leaves and seeds i.e., vegetables and crops were tomatoes, coriander, wheat, rice, maize, pulses, and weeds. A total of 191 individuals 67 males and 124 females were collected from four localities of Hyderabad region. The Body ochreous colour, with stripes on head, pronotum, scutellum and stripped connexiva. The species is redescribed on the basis of morphological characters, especially colour, shape of head, pronotum, scutellum, antennal segments, and internal male genitalia (Pygophore, paramere and aedeagus) and female genitalia (terminalia and spermatheca). A general description of C. pudicus is also given. The species of Carpocorini (stink bugs) is new record of Hyderabad region.

Abstract:

Phylogenetic analyses of the 13 species of the subgenusLyciptabased on morphological characters were performed under equal and implied weighting, following the method of Mirande (2009). Species fromDichelops,Ladeaschistus,Proxys,Spinalanx,Euschistus(Euschistus) andEuschistus(Mitripus) were included as outgroups, and the tree rooted onCarpocoris. Sixty-five morphological characters were coded in the data matrix. The cladistic analyses did not recover the monophyly of the subgenusLycipta. A clade was supported based on characters of the pygophore and female ectodermal ducts strengthening a new definition ofEuschistus(Lycipta). One species,Euschistus monrosi, was excluded from the subgenus and transferred to the nominal subgenus.Euschistus(Lycipta) species are distributed in two Neotropical subregions: Brazilian (Pará, Rondônia and Yungas provinces) and Chacoan (Pampean, Atlantic, Parana andAraucariaForests and Puna provinces). Biogeographical analyses of spatial vicariance were performed employing different sets of parameters and allowed to identify five disjunctions nodes.

Abstract:

The assassin bug tribe Metapterini belongs to the subfamily Emesinae (Hemiptera: Heteroptera: Reduviidae). Morphologically, it is characterized by the conspicuous basal process of the posteroventral series in the foreleg and the presence of wing polymorphism, with a high proportion of the genera with micropterous or apterous species. Here, the male and female ectodermal genitalic structures are documented for ten genera and twenty-three species of Metapterini, including eight species of the speciose genus Ghilianella Spinola, 1850. Descriptions and digital macrophotographs are provided for abdominal segment 8, pygophore, parameres, and phallus of the male, and for tergite 8, tergite 9, gonocoxae, gonapophyses, gonoplac, and bursa copulatrix of the female. The asymmetric male genitalia within Emesinae are discussed. From this morphological documentation sixty six phylogenetic characters are coded, presented as a data matrix and analyzed cladistically, and their potential usefulness for resolving relationships among Metapterini is discussed.

Abstract:

Potamobates Champion, 1898 (Hemiptera: Heteroptera: Gerridae) heretofore included 18 species distributed from southern Mexico to Peru. They display a distinct morphology, especially regarding the projections of abdominal segment VIII. Specific identification and delimitation are difficult, and the genus lacks a thorough revision and evaluation of inter- and intraspecific variation. Here, we revise Potamobates, redescribe and/or illustrate known species, and describe P. molanoi Floriano and Moreira, sp. nov. and Brailovskybates Floriano and Moreira, gen. nov. The new genus is erected for P. thomasi Hungerford, 1937 and is characterized by the following features: (1) abdomen elongated, longer than the mesothorax; (2) abdominal spiracles positioned at the center of the segments; (3) male abdominal segment VIII without projections; (4) male pygophore and proctiger not rotated in relation to the longitudinal axis of the body; (5) female abdominal tergum VIII subequal in length and width; (6) and posterior margin of female abdominal sternum VII not produced medially, with a pair of lateral projections.
