III.—Idatiella China: Two new species,with a key (Hemiptera,Miridæ)

Summary

Nine soil, freshwater, and marine species of Thecamoeba have been isolated and investigated, and nine other probably or possibly valid species were reviewed from the literature. Locomotive form/behaviour and interphase nuclear structure are adequate to distinguish all known species, and on that basis the diagnoses of several species have been clarified and questions of possible synonymy resolved.

Most known species can be placed into either a rugose or a smooth group, but it is not yet clear that the genus can be formally divided along that line.

Feeding experiments and observations on six soil and freshwater species showed interspecific differences in the kind of protozoan prey ingested. Species also differed in their rate of multiplication in culture.

One recently discovered species, T. proteoides, approaches Amoeba proteus in both morphological and cultural characteristics more than does any other known species of Thecamoeba but is clearly a member of the latter genus.     

Five new species of Homalotylus Mayr (Hymenoptera: Encyrtidae) − from India with a key to Indian species

Five new species of Homalotylus Mayr (Hymenoptera: Encyrtidae) – H. noyesi sp. nov., H. biharensis sp. nov., H. varicolorus sp. nov. (from Bihar province), H. montanus sp. nov. (from Tamil Nadu province) and H. insularis sp. nov. (from Andaman and Nicobar Island) – are described from India. A revised key to the Indian species of Homalotylus is provided.

A new species and the phylogeny of the South American genus Gromphas Brullé, 1837 (Coleoptera: Scarabaeidae: Scarabaeinae: Phanaeini)

Gromphas jardim Cupello & Vaz-de-Mello sp. nov. is described from Bolivia and Central Brazil and is endemic to the biogeographic province of Rondônia. It resembles Gromphas amazonica and Gromphas inermis, but is distinguished primarily by the pattern of pronotal granulation and the form of the apical tubercle of male protibiae, which is modified in a tapered spur. Based on 31 morphological characters, a phylogenetic analysis returned a single most parsimonious tree where Gromphas is monophyletic and has the following internal topology: ((G. aeruginosa + G. lemoinei) (G. dichroa (G. inermis (G. amazonica + G. jardim)))).
