Comparative morphology of the tongue in free-tailed bats (Chiroptera, Molossidae)

Descriptive and comparative studies on tongue of nineteen Molossidae, one Mystacinidae, and four Vespertilionidae bats species were carried out. Analysis was restricted to the external morphology, covering general shape of the tongue and its papillae. Types of papillae and their distribution presented considerable intergeneric variation, considering the strictly insectivorous feeding habits of these bats. Distribution of the data of tongue morphology is analyzed and compared with the phylogenetic schemes proposed previously and comments about evolutionary relationships among taxa were done.

Morphology of three Brazilian species of Semiotus (Coleoptera, Elateridae, Semiotinae)

The morphology of Semiotus distinctus (Herbst, 1806), S. intermedius (Herbst, 1806) and S. ligneus (Linnaeus, 1767), including mouthparts and male and female genitalia, is described and illustrated. A comparative analysis of the characters related to the external morphology, mouthparts and male and female genitalia is also included.

Morphology and dynamics of male gametogenesis in Sympterygia bonapartii (Chondrichthyes, Rajidae) from Northern Patagonia

ABSTRACT The smallnose fanskate, Sympterygia bonapartii Müller & Henle, 1841 is one of the most disembarked items in commercial harbors in Argentina. In this work, the microscopic architecture of mature male gonads and the dynamics of cysts development are analyzed as a contribution to awareness of the reproductive biology of the species. Some biological data related to reproduction are given as well. Two seasons were sampled (fall and spring) and length classes's frequency distribution and maturity stages frequency distribution are given. Size at first sexual maturation for males was estimated at 57 cm of total length. Testes are symmetric, peer, lobed, with several germinal zones. Inside the gonads, there are many spermatocysts, containing reproductive cells at the same developmental stage. On the basis of their cytological and microanatomical features, several maturative degrees of the spermatogenic series were differentiated. Few Leydig cells were recognized at the interstitial tissue among cysts. The microscopic and semiquantitative analysis performed in this work provides morphological information about male gametogenesis and some biological data for the North Patagonian population of this economically and ecologically important species.

Taxonomy of the Brazilian firefly Cladodes illigeri (Coleoptera, Lampyridae): morphology and new records

ABSTRACT Cladodes illigeri (Kirby, 1818) is redescribed, and can be distinguished by the following features: color pattern overall black, paired spots and elytral margins pale yellow; pygidium bisinuate, posterior angles rounded, as long as median margin; and aedeagus with phallus 1/3 shorter than the parameres, which are sinuated apically. Cladodes lamellicornis (Motschulsky, 1854) is proposed as a junior synomym of C. illigeri. New records from the Atlantic Rainforest and illustrations for structural features are provided.

Comparative morphology of the type-species of Isotes and Synbrotica(Coleoptera, Chrysomelidae, Galerucinae), with a new synonymy of species

ABSTRACT In order to solve the affinities of the species of Isotes Weise, 1922, a detailed morphological comparative study was carried out based on type-species of Isotes and its junior synonym,Synbrotica Bechyné, 1956. Isotes tetraspilota (Baly, 1865) and Isotes borrei (Baly, 1889) had their morphology of mouthparts, endosternites, wings and both male and female genitalia compared by the first time. A new synonymy is established between Isotes borrei (Baly, 1889) and Isotes crucigera (Weise, 1916) syn. nov. based on external and genitalia morphology. New structures for Section Diabroticites Chapuis, 1875 are presented and discussed.
