| [triatoma jurbergi sp. n. from the state of mato grosso, brazil (hemiptera, reduviidae, triatominae) with an updated list of synonyms and other taxa]. | triatoma jurbergi n. sp. is described based on nine specimens of both sexes deposited in the rodolfo carcavallo collection in the oswaldo cruz institute entomological collection. the new species can be separated from the closely related triatoma guazu lent & wygodzinsky, 1979 by several characters. the most important are longer anteocular region; thin and pointed juga: the shape of the eyes without concavity in the posterior edge; much longer second rostral segment, passing the posterior edge of ... | 1998 | 9711334 |
| comparative study of the stridulatory sulcus, buccula and rostrum of the nymphs of triatoma guazu lent & wygodzinsky, 1979 and triatoma jurbergi carcavallo, galvão & lent, 1998 by scanning electron microscopy (hemiptera, reduviidae). | the ultrastructural morphology of the ventral region of the head (rostrum and buccula) and proesternum (stridulatory sulcus) of nymphs from the 1st to 5th instars of triatoma guazu lent & wygodzinsky, 1979 and triatoma jurbergi carcavallo, galvão & lent, 1998 was described. morphological differences between the two species and of the five nymphal stages development of each species were observed. these structures showed systematic differential characteristics of the studied species and may be use ... | 2003 | 12886412 |
| chromosomal characteristics and distribution of constitutive heterochromatin in the matogrossensis and rubrovaria subcomplexes. | since 1966 the triatomines were grouped in complexes and specific subcomplexes. although the complex and subcomplexes not have taxonomic importance, should be monophyletic groups and cytogenetic tools have proved to be of great importance to characterize these species groupings. based on this, this paper aims to describe the chromosomal characteristics and heterochromatic pattern of matogrossensis and rubrovaria subcomplexes, in order to contribute to the taxonomic and evolutionary relationships ... | 2015 | 25917494 |
| comparative ultrastructural analysis of the antennae of triatoma guazu and triatoma jurbergi (hemiptera: reduviidae) during the nymphal stage development. | the specific concept of two triatominae species of epidemiological importance in the mato grosso region (brasil), triatoma guazu lent & wygodzinsky, 1979 and triatoma jurbergi carcavallo, galvão & lent, 1998, the antenniferous tubercle and the four antennal segments of nymphs from the first to fifth instar were morphologically compared by scanning electron microscopy. the main differences observed were that the antenniferous tubercle in t. guazu did not present a smaller tubercle in the base of ... | 2002 | 12349851 |
