The giant water bug, Lethocerus indicus (Lepeletier and Serville) (Heteroptera: Belostomatidae), a native species of Southeast Asia, is one of the largest insects belonging to suborder Heteroptera. In this study, the meiotic chromosome of L. indicus was studied in insect samples collected from Thailand, Myanmar, Loas, and Cambodia. Testicular cells stained with lacto-acetic orcein, Giemsa, DAPI...

Heteroptera is a worldwide distributed group of insects inhabiting both terrestrial and aquatic habitats and has an important ecological role. A survey of aquatic and semiaquatic Heteroptera from Cuba is provided based on literature reports and field collections. General data on species geographical distribution are given, along with altitude and collection season. Representatives of 86 species...

Mitosis and male meiosis were studied in Myrmedobia coleoptrata (Fn.), (Heteroptera, Microphysidae). Spermatogonial metaphase revealed 14 chromosomes (2n=12 + XY). The nucleolar organizing region was found on the X chromosome. No m-chromosomes were present in the complement. Male meiotic prophase was characterized by a prominent condensation stage. At this stage, the sex chromosomes were positi...

Malaise trap sampling of Hemiptera (Heteroptera; Auchenorrhyncha) was conducted at 500 m intervals along an elevational gradient from 200 m to 3,700 m on the east slope of Mount Wilhelm, Madang Province, Papua New Guinea. Hemiptera had a decrease in morphospecies richness and overall abundance with increasing elevation, however, the Heteroptera did not exhibit either pattern. A few species were...

Limnobatodes paradoxus Hussey, 1925 is a primitive hydrometrid, described from a single female specimen collected in 1923 at Tela, Honduras (Hussey 1925). Following the original description, very few records of this species have been reported in literature, and locality indications are not detailed: Brazil (Cobben 1968), Peru (Andersen 1977), and French Guiana (Polhemus & Polhemus 1995). Anders...

Abstract Germalus kozari sp. nov. (Hemiptera: Heteroptera: Lygaeoidea: Geocoridae) is now described. Comparative notes, keys, diagnoses, and distribution data to allied Indomalayan species provided. greeni reported for the first time from outside of India Sri Lanka.

Hemiptera, the largest non-holometabolous order of insects, represents approximately 7% of metazoan diversity. With extraordinary life histories and highly specialized morphological adaptations, hemipterans have exploited diverse habitats and food sources through approximately 300 Myr of evolution. To elucidate the phylogeny and evolutionary history of Hemiptera, we carried out the most compreh...

Tingidae (Hemiptera: Heteroptera) collected in Vietnam by several institutions between 1958 and 2013 continue to yield new information about tropical diversity in this family of insects. Herein, thirty-seven species are newly recorded for Vietnam, and four are described as new to science. Comments on their affinities and distribution are provided, highlighting the biological richness of a rapid...

Three new species of the Carpocorini are described: Euschistus (Euschistus) baranowskii Eger & Bianchi sp. nov. from Jamaica, Euschistus (Mitripus) saramagoi Bianchi, Cioato & Grazia sp. nov. from Brazil, and Ladeaschistus borgesi Bianchi, Cioato & Grazia sp. nov. from Argentina, Bolivia and Brazil. Comparative illustrations of external and internal genitalia of the species are provided.

Only six species of Microvelia have been recorded from Colombia up to the present, namely M. ancona, M. hinei, M. leucothea, M. longipes, M. panamensis, and M. pulchella. Microvelia inguapi sp. n. and M. piedrancha sp. n. are herein described and compared with similar species. An identification key to the Colombian species of Microvelia is presented.
