The new riodinid genus Dachetola, tribe Riodinini, is described and illustrated from Central and South America. Four species are recognized: azora Godart, [1824], and virido Lathy, 1958, are transferred from Chalodeta Stichel to Dachetola (comb. novs.), and caligataStichel, 1911, and pione Bates, 1868, are transferred from Calospila Geyer to Dachetola (comb. novs.). Dachetola is hypothesized to be most closely related to Metacharis Butler.
The genus Calociasma appears to be polyphyletic and contains members that belong to all three currently recognized subtribes of the Nymphidiini. Only the type species, ictericum, and laius are retained in Calociasma, which belongs to the subtribe Nymphidiina. The taxa pulcherrima, comparata and felicis are removed to Juditha (n. combs.) in the Lemoniadina, and lilina (n. comb.) and its newly described sister species from Panama, robbinsin. sp., are placed in the new genus Calicosaman. gen. in the Theopeina. Calicosama is characterized, and its biology and systematic position discussed.
Mirabilamorbus monteithi, new genus and new species, is described from Northern Territory and Western Australia. It is placed in the coreid tribe Amorbini. Comments are made on the variability in body size and shape of hind femora. Dorsal view and details of the male genital capsule and parameres are illustrated. A key to the Australian genera of Amorbini is included.
The water strider species of the genus Ptilomera occurring in Indochina are reviewed, and two new species are described and figured: P. fang from northern Thailand, and P. burmana from northern Burma. Keys to species for both males and females are provided for all taxa found in the region, accompanied by detailed distributional records and range maps.
The four new species Hyalochloria apicata, H. bispina, and H. marginatus from Brazil, and H. baranowskii from Panama and Trinidad, are described; H. rondoniensis Carvalho is synonymized under H. scutellata Henry; males of H. antilleana Carvalho and H. araripensis Carvalho are described for the first time; confusion pertaining to the identity of H. caviceps and H. unicolor is clarified; a lectotype for H. caviceps Reuter is redesignated; and numerous new distribution records are given. Photographs of adults, illustrations of male antennae, and a revised identification key to the 20 known species are provided to facilitate recognition.
Corrections to the 1995 catalog of Miridae entitled “Plant Bugs of the World” are presented. These include taxa and references omitted from the catalog, corrections of synonymies, and corrections of other errors such as spellings of scientific names and incorrect distributional information. A new replacement name Rondonegeria nom. n. is proposed for the preoccupied name Egeria Carvalho and Costa, 1993.
A recently-published phylogenetic tree, constructed using the neighbor-joining algorithm, summarized relationships among 37 species of Coleoptera (Insecta) indicated by a 400 base pair region of the mitochondrial cytochrome oxidase I gene. This study included sequences from four species of the family Coccinellidae. The relationships of the four coccinellids indicated by the published neighbor-joining tree are congruent with current hypotheses of their relationships based on adult, larval, and pupal morphology. However, re-analysis of the molecular sequences for these taxa using standard parsimony methods reveals a more complex situation in which the use of different outgroups and different tree-searching algorithms yields strikingly different topologies, many of which do not correspond to the pattern of relationships derived from morphological data. These sequences may simply be too variable and too highly convergent to accurately reflect the phylogenetic history of Coccinellidae.
