Oragua Melichar, 1926: key to species from southeastern Brazil and a new species from Rio de Janeiro State (Insecta: Hemiptera: Cicadellidae: Cicadellini)

A new species of Oragua Melichar, 1926 is described and illustrated from the Atlantic rainforest of Rio de Janeiro State, southeastern Brazil, based on specimens collected in Casimiro de Abreu (Oragua casimirensis n. sp.). The new species can be distinguished from the other species of the genus by the following combination of features: dorsum dark brown with dispersed yellow dots and spots; male pygofer with well developed dentiform process, directed inwards, on posterodorsal portion; subgenital plates subtriangular and elongate, expanded basally, not extending as far posteriorly as location of dentiform pygofer processes; aedeagus slender and elongate, with pair of apical processes weakly connected to shaft; paraphyses with rami elongate, slightly asymmetrical, approximately parallel to each other. A key to males of the six Oragua species recorded from southeastern Brazil is provided. We propose a group of species within Oragua (linnavuorii group) based on features of the male genitalia of O. flavolineata Mejdalani, Silva & Takiya, 2016, O. linnavuorii Mejdalani, Silva & Takiya, 2016, and O. casimirensis n. sp.

Taxonomic review of Spiladarcha Meyrick (Lepidoptera: Urodoidea: Urodidae) with a new species from Venezuela

Spiladarcha adamskii sp. nov. is described from Venezuela and is compared to S. derelicta, the type species of the genus. Spiladarcha is characterized by the features of male genitalia, which have not been known previously for the genus. Spiladarcha are distinguished from its sister genus Wockia in having raised scales of small black spots along the upper surface of the forewing veins, a pair of setal zones on the apical part of the tegumen in the male genitalia, and a linguiform antrum and a zone of longitudinal pleats on the ductus bursae in the female genitalia.     

Description of a second species of Nannogonalia Young, 1977 (Insecta: Hemiptera: Cicadellidae: Cicadellini) from the Atlantic Forest of south Brazil

A second species of the poorly known sharpshooter genus Nannogonalia Young, 1977 is described and illustrated from the Atlantic Forest of south Brazil (state of Paraná). Types are deposited in DZUP. Nannogonalia inusitata n. sp. can be distinguished from the type-species (Tettigonia circumcincta Signoret, 1855) mainly by the color pattern and form of the male subgenital plates and female sternite VII. Nannogonalia circumcincta is newly recorded from the state of Paraná. The female genitalia of Nannogonalia are described in detail for the first time, based on the type-species and the new species. We discuss some peculiar features of the first and second ovipositor valvulae of this genus that were previously observed in Versigonalia Young, 1977.

A new Swartzia (Leguminosae: Papilionoideae: Swartzieae) species with trimorphic stamens from Amazonian Brazil

A new species Swartzia trimorphica Mansano & A. L. Souza (Leguminosae, Papilionoideae, Swartzieae) from the Amazonian Brazil, is described and illustrated. The new species is notable and distinct from all the other species of Swartzia by its highly unusual trimorphic stamens, while the other species have either an isomorphic or a dimorphic androecium. The new species is included in the section and subsection Swartzia , ser. Orthostylae based on its bracteolate pedicels, the cauligerous inflorescences, lateral style and the relative size of the ovary compared to the style. The atypically small gynoecium in the material suggests the possibility that flowers may be functionally unisexual. Field observations and more collections are needed to resolve this question.  © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society , 2005, 147 , 235–238.

Resource allocation and bionomics of indigenous and exotic Cotesia (Hymenoptera: Braconidae) species reared on Sesamia calamistis

The braconid larval parasitoids Cotesia chilonis (Matsumura), C. flavipes Cameron and a strain of Cotesia sesamiae (Cameron) from coastal Kenya, reared at the International Centre of Insect Ecology and Physiology, were introduced at the International Institute of Tropical Agriculture in the Republic of Benin for suitability testing on West African stemborers prior to release. C. chilonis was originally collected in Japan while C. flavipes was imported into Kenya from Pakistan. The host species used was the noctuid Sesamia calamistis (Hampson), the most important noctuid maize pest in the region. All three Cotesia species attacked and successfully developed in 2nd to 6th larval instar of S. calamistis but parasitoid-induced mortality was highest on second instars. On most instars, C. sesamiae and C. flavipes produced larger broods than C. chilonis. Larvae parasitized by C. sesamiae developed to the 6th instar and attained an average larval weight of 353 mg, while larvae parasitized by C. chilonis only molted to the 4th instar and attained a maximum weight of 107 mg. The lower developmental threshold estimated from the non-linear regression of temperature on developmental rate was 15.9, 15.9 and 14.9 degrees C for C. chilonis, C. sesamiae and C. flavipes, respectively, while the maximum temperature was 34.2, 35.2 and 33.8 degrees C, respectively. A maximum of four ovipositions were observed per female during a life span ranging from 1.3 days for C. chilonis and C. flavipes to 1.6 days for C. sesamiae. The largest adult progeny, intrinsic rate of increase and net reproductive rates were recorded at 28 degrees C for all species. However, across temperatures, C. flavipes yielded the highest number of offspring, followed by C. sesamiae and C. chilonis. The sex ratios did not vary significantly with species and temperature. Thus, the reproductive potentials of C. sesamiae and C. flavipes were greater than that of C. chilonis.
