A longitudinal study of two species of Belostoma Latreille (Heteroptera: Belostomatidae): allometry and ontogeny Neotropical Entomology
Iglesias,Mónica S.; Gaspe,María S.; Valverde,Alejandra C..
The multivariate allometric growth patterns from longitudinal data of leg and rostral segments of all instars of Belostoma elegans (Mayr) and B. cummingsi De Carlo are presented for the first time, and the allometric coefficients are compared. The segments of the middle and hind legs present allometric coefficients with opposite polarity to those of forelegs. This discrepancy in the ontogenetic trajectories may be due to the different functions of the legs. The foreleg main function is to capture of the prey, while the middle and hind legs are adapted to swimming. The relative size of rostral segments is an important taxonomic character in Belostoma. In B. cummingsi, the proximal segment is longer than the middle one, while in B. elegans they are subequal....

A new species of Laranda Walker 1869 (Orthoptera: Grylloidea, Phalangopsidae) from remnant patches of the Brazilian Atlantic Forest Neotropical Entomology
Mews,Carina M.; Lopes-Andrade,Cristiano; Sperber,Carlos F..
The genus Laranda has six described species and is confined to South and Southeast of Brazil. We describe a new species and discuss the biology and distribution of the genus. The new species can be distinguished from its known congeners by the following characteristics: absence of yellow spots on pronotum and base of posterior tibiae; female copulatory papilla: sclerotization in dorsal view forming opposing acute angles, apical lobes narrow and small; male genitalia: pseudepiphallic median process short and wide; pseudepiphallic paramere with apex incurved and ectophallic fold surpassing apex of the parameres. The genus is distributed within the Atlantic Forest biome; the new species is found on tree trunks, as well as on forest leaf litter.

Description and key to the fifth-instars of some Cicadas (Hemiptera: Cicadidae) associated with coffee plants in Brazil Neotropical Entomology
Maccagnan,DHB; Martinelli,NM.
Fifth-instars of the cicada species Dorisiana drewseni (Stål), Dorisiana viridis (Olivier), Fidicina mannifera (Fabricius), Fidicinoides pronoe (Walker) and Carineta fasciculata (Germar) are described and illustrated. Moreover, a key to the nymphs of these species along with Quesada gigas (Olivier) is also provided.

Experimental infestation with the immatures of Amblyomma dissimile Koch, 1844 (Acari: Ixodidae) on Tropidurus torquatus (Lacertilia: Iguanidae) and Oryctolagus cuniculus Arq. Bras. Med. Vet. Zootec.
Freitas,L.H.T.; Faccini,J.L.H.; Daemon,E.; Prata,M.C.A.; Barros-Battesti,D.M..
Larvas provenientes de duas fêmeas de Amblyomma dissimile Koch, 1844 (Acari: Ixodidae), naturalmente ingurgitadas em uma iguana (Iguana iguana) e provenientes do Estado do Mato Grosso, foram utilizadas na infestação experimental de lagartos da espécie Tropidurus torquatus e coelhos domésticos. As larvas alimentadas em ambos os hospedeiros realizaram ecdise para ninfas. As ninfas apenas ingurgitaram no lagarto e mudaram para machos e fêmeas. Este é o primeiro registro do parasitismo de larvas e ninfas de A. dissimile em T. torquatus e de larvas em coelhos.

Morphological study of the thorax of the five nymphal instars of Triatoma arthurneivai Lent & Martins (Hemiptera, Reduviidae, Triatominae) Rev. Bras. entomol.
Rosa,João Aristeu da; Medeiros,Marcello Pereira; Cilense,Mario; Barata,José Maria Soares.
Scanning electron microscope (SEM) was done in order to study dorsal, ventral and lateral sides of 1st, 2nd, 3rd, 4th and 5th nymphal instars of Triatoma arthurneivai. The five nymphal instar can be recognized based on different pronotum, mesonotum and metanotum shapes and characteristics. In the 1st instar collar, hairless areas and tubercles are absent. The 2 nd instar presents collar, hairless areas and tubercles. In the 3rd instar occurs the development of wing pads. In the 4 th instar the four wing pads are expanded, but do not reach the abdomen and in the 5th instar the anterior wing pads almost overlap the posterior ones. At the ventral side, two metasternal glands openings (1+1) were found in all five nymphal instars. Brindley's gland evaporation...

Morphology of immatures of Euschistus (Mitripus) grandis (Insecta: Hemiptera: Pentatomidae) Rev. Bras. Zool.
Biasotto,Larissa Donida; Bianchi,Filipe Michels; Campos,Luiz Alexandre.
Immatures are important sources of information about characters, thus potentially improving classification and phylogenies. Euschistus (Mitripus) grandis Rolston, 1978 occurs in southern and southeastern Brazil. There are no references in the literature about this species other than the original description and distribution records. Our aim is to describe the egg and five nymphal instars of E. (M.) grandis, addressing the ontogeny of the external scent efferent system. Specimens of E. (M.) grandis were collected on Solanum pseudocapsicum Linnaeus (Solanaceae) in São Francisco de Paula, Rio Grande do Sul, Brazil, and reared in the laboratory. The egg of E. (M.) grandis is white and barrel-shaped, chorion translucent bearing spines connected by thin sheets...

Morphology of the immatures and biology of Chinavia longicorialis (Breddin) (Hemiptera: Pentatomidae) Neotropical Entomology
Matesco,Viviana C; Schwertner,Cristiano F; Grazia,Jocelia.
Chinavia longicorialis (Breddin) is recorded only in Brazil, Argentina and Uruguay on host plants of at least three different families. Adults and nymphs were reared under standard controlled conditions (24 ± 1°C; 70 ± 10% RH; 12hL:12hD), and fed on green beans (Phaseolus vulgaris L.). Eggs and first instars of C. longicorialis are very similar to those of other species of Chinavia; however, the presence of orange maculae at the thoracic pleura is exclusive of first instars of C. longicorialis. Third to fifth instars have abdominal maculae divided by pseudo-sutures, a diagnostic feature of C. longicorialis nymphs. Light and dark morphs were observed for third, fourth and fifth instars. Head width measurements did not overlap between consecutive instars....
