Immature stages of Calycopis bellera (Hewitson) and C-janeirica (Felder) (Lepidoptera, Lycaenidae, Theclinae, Eumaeini): Taxonomic significance and new evidence for detritivory

Details of egg, larval, and pupal morphology are described and illustrated for Calycopis bellera (Hewitson) and C. janeirica (Felder), with a special emphasis on larval chaetotaxy. Wild-caught Calycopis females laid eggs on dead leaves in the laboratory, and the caterpillars successfully completed development on an artificial agar diet to which no leaves were added. Males and females of the sexually dimorphic C. bellera had been previously placed in different genera or different species groups. Calycopis janeirica had been chronically misidentified (and misspelled C. jeneirica). Males and females of this species appear to be correctly associated for the first time. Whereas C. bellera has five larval instars-as reported previously for C. caulonia-C. janeirica has four. Morphological characters of the immatures of C. bellera and C. janeirica are summarized in a table and compared with those of other reared Calycopis species.

Redescription of the larva of Amblyomma oblongoguttatum Koch, 1844 (Acari: Ixodidae) by light and scanning electron microscopy

The larval stage of Amblyomma oblongoguttatum Koch is redescribed using optical and scanning electron microscopy. Unfed larvae were obtained from a colony of A. oblongoguttatum originated from engorged females collected on domestic pigs from Monte Negro municipally (10 degrees 29'S, 63 degrees 32'W), State of Rondonia, Western Amazon, Brazil. Several characters are presented including the chaetotaxy of the idiosoma, palpi and Haller's organ, as well as morphological features of the idiosoma, gnathosoma and legs. In addition, the porotaxy (topographical and numerical patterns of integumentary structures) were presented by using a new nomenclature recently proposed. The chaetotaxy of the larvae of A. oblongoguttatum, in general, is similar to other Neotropical Amblyomma species. Three types of integumentary structures were observed on the idiosoma: lyrifissures, small glands, and large wax glands. Topographic and numerical patterns of the integumentary structures consisted of 5 pairs of large wax glands (1 dorsal/4 ventral), 24 pairs of lyrifissures (11 dorsal/13 ventral), and 49 pairs of small glands (28 dorsal/21 ventral). These topographic and numerical patterns found for A. oblongoguttatum show only minor differences when compared with patterns of other Amblyomma larvae, however, a few key features can be used for identification of these species.

A NEW GENUS AND SPECIES OF PHILOPTERIDAE (PHTHIRAPTERA: ISCHNOCERA) FROM THE TRUMPETERS (AVES: GRUIFORMES: PSOPHIIDAE)

A new chewing louse genus and species belonging to the Philopteridae, namely, Palmaellus inespectatus n. gen., n. sp., is described. The new genus is distinguished from the other ischnoceran genera hitherto described by its peculiar characters of the dorsal anterior head plate with 2 postero-lateral projections, pterothorax and abdomen with scarce chaetotaxy, male genitalia with simple mesomere and paramere lacking inner digitiform projection, and the genital region of female with postero-vulvar plates bearing setae. It is a parasite of the trumpeters, an avian family endemic to South America's Amazon Basin.

Description of immature stages of Phelypera schuppeli (Boheman, 1834) with comments on natural history (Coleoptera: Curculionidae: Hyperinae)

Immatures of the Phelypera schuppeli (Boheman, 1834) (Curculionidae; Hyperinae; Cepurini) are described, illustrated and compared with available descriptions of larvae and pupae of Hyperini. Immatures and adults from midwest (Dourados, Mato Grosso do Sul; Pirenopolis, Goias) and southeast Brazil (Bauru, Sao Paulo) were found on leaves of the host plant, Pachira aquatica Aubl. (Malvaceae, formerly Bombacaceae), a tree used as an ornamental plant in many Brazilian frost-free cities. Larvae of P. schuppeli are exophytic, brightly colored, eruciform and possess abdominal ambulatory ampullae, resembling larvae of Lepidoptera. Mature larvae can spin globular lattice-like cocoons where pupation takes place. Data in the field and under laboratory conditions confirmed previously published biological observations on P. schuppeli. Additional information about defensive behaviors, process of cocoon construction and natural enemies, such as the larval predator Supputius cinticeps (Stal, 1860) (Hemiptera: Pentatomidae) and the prepupal and pupal parasitoid Jaliscoa nudipennis Boucek, 1993 (Hymenoptera: Pteromalidae), are reported.

A new species of Schizotetranychus (Acari, Prostigmata, Tetranychidae) from the Chilean fauna, with a few remarkable morphological features

Schizotetranychus tegophallos sp. nov., from papyrus sedge (Cyperus involucratus Rottb., Cyperaceae) from Santiago, Chile, is described and figured. The genital stylets of the male, palpal tarsus tactile setae and chaetotaxy of leg IV trochanter in deutonymphs are discussed.
