1992, David W. Roubik, editor, Ecology and Natural History of Tropical Bees, page 45:

In further support of the antiquity of this clade is the widely disjunct distribution of some of its basal members among the dasypodaine melittids, as indicated in Sections 26 and 68 and Michener (1981a).

2000, Charles Duncan Michener, The Bees of the World, volume 1, page 95:

The relatively good fossil representation of melittids and their long-tongued associates has been argued to be a reflection of a bias in favour of resin-collecting bees.

meloid

Cantharidin is sometimes referred to as Spanish fly because of its derivation from adults of the large meloid Lytta vesicatoria that is commonly found in Spain; it is a potent vesicant with a putative function as an aphrodisiac.

1981, Murry Blum, Chemical Defenses of Arthropods, page 20:

Meloids are herbivorous as adults, and their larvae are parasites of bees or eat grasshopper eggs.

2002, Frank N. Young, Jr., Gene Kritsky, A Survey of Entomology, page 200:

Cantharidin is also a potent blistering agent.[…]Individual meloids may contain as much as 17 milligrams of cantharidin, or 10% of live weight.

2005, Thomas Eisner, Maria Eisner, Melody V. S. Siegler, Secrets Weapons: Defenses of Insects, Spiders, Scorpions, and Others Many-Legged Creatures, page 221:

2009, "Coleoptera", entry in Vincent H. Resh, Ring T. Cardé (editors), Encyclopedia of Insects, page 198,

The meiolaniids were ancient turtles that evolved during the Eocene epoch, between 55 and 34 million years ago. Fossils of meiolaniid species come from Argentina, from Australia, and from several islands near Australia, including Tasmania and New Caledonia.

2007, Rebecca Stefoff, Turtles, page 52:

Turtle remains are particularly common at Lightning Ridge, comprising several distinct lineages including aquatic chelids and peculiar meiolaniid-like taxa—meiolaniids were spectacular horned turtles known from the Australian region and South America.

2012, Elizabeth T. Smith, Benjamin P. Kear, “Chapter 9: Spoochelys ormondea gen. et sp. nov., an archaic Meiolaniid-Like Turtle from the Early Cretaceous of Lightning Ridge, Australia”, in Donald B. Brinkman, Patricia A. Holroyd, James D. Gardner, editors, Morphology and Evolution of Turtles, page 121:

Meiolaniids are a peculiar group of extinct turtles bearing cranial horns and frills, caudal rings, and tail clubs and restricted to South America (Eocene) and Australasia (Oligocene to Holocene).

Flowers with long, tubular corollas are visited mainly by long-billed meliphagids; the latter, however, also visit flowers of other types.

1985, Allen Keast, An introductory ecological biogeography of the Australo-Pacific Meliphagidae: New Zealand Journal of Zoology, volume 13, number 4, page 620:

The meliphagids, as their common name implies, are primarily nectar feeding or nectarivorous and were quite possibly prevented from any significant adaptive radiation on each main island by competition from the (presumably) earlier radiated Hawaiian honeycreepers.

2002, Alan C. Ziegler, Hawaiian Natural History, Ecology, and Evolution, page 263:

I am not familiar with any detailed studies of the ecology of nectarivores in the brushtongued parrots, meliphagids, and certain marsupial mammals in forests of Australia and New Guinea.

Why Ophiothricidae is a misspelling
According to the International Code of Zoological Nomenclature, taxonomic family names are formed from the stem of the name of the type genus (Ophiothrix), which is the genitive singular form after the ending is removed.
The consonants in Ancient Greek θρῐ́ξ (thríx, “hair”) are due to the underlying χ (aspirated) in the stem becoming ξ (unaspirated) before the nominative singular ending, ς.
The genitive singular form is τρῐχός (trikhós) instead of *θρῐχός (*thrikhós), due to Grassman's Law, which deaspirates θ to τ when there is an aspirated consonant in the next syllable (the χ). The stem of Ophiothrix is thus "Ophiotrich-"

1975, Dudley W. Bolyard, Deep drilling frontiers of the central Rocky Mountains, Rocky Mountain Association of Geologists, →OCLC, page 114:

In proportions, and especially in their uncompressed central metatarsal, Avisaurus retains the conservative condition seen in such basal theopods as Coelophysis and Ceratosaurus (Fig. 2), and thus retains a basal condition compared to derived theropods and Archaeopteryx, which have proximally pinched central metatarsi (eg, compsognathids, ornitholestids, allosaurids, tyrannosaurids, elmisaurids, ornithomimids, dromaeosaurs and saurornithoidids; Paul, 1984).

1985, MK Brett-Surman, “A new family of bird-like dinosaurs linking Laurasia and Gondwanaland”, in Journal of Vertebrate Paleontology, volume 5, number 2, page 133:

Aublysodonts and tyrannosaurs appear to have been the culmination of the ornitholestid-allosaur-tyrannosaur group.

1966, Kenneth Stafford Norris, Whales, Dolphins, and Porpoises, page 663:

She proved the independence of the evolutionary development of osmerids and plecoglossids which form an independent suborder and clearly outlined main traits of similarity and difference of the Salmonoidei and the osmerids.

1995, Acta palaeornithologica: 3, Symposium SAPE: 5, Internationale Senckenberg-Konferenz, 22-26, Juni 1992, page 72:

2010, John Wesley Tunnell, Encyclopedia of Texas Seashells, page 183:

The genus name is a good descriptor of the shells of personids, most of which are moderately to severely distorted.

Some of the Australian specimens are classified with the psychopsids (family Psychopsidae), an alder fly group occurring solely in Australia, where it is known as the silky lace-wing due to the brilliantly colored wings and the long, silky hair.

1976, Bernhard Grzimek, Grzimek's Encyclopedia of Evolution, page 265:

As will be repeatedly seen in many Neuroptera families, psychopsids had a wider distribution during the Mesozoic and Tertiary.

2005, David Grimaldi, Evolution of the Insects, page 342:

While many fossil psychopsids were recorded from the Mesozoic, few representatives have been described from the Tertiary.

2011, Yuanyuan Peng, Vladimir N. Makarkin, Xiaodong Wang, Dong Ren, “A new fossil silky lacewing genus (Neuroptera, Psychopsidae) from the Early Cretaceous Yixian Formation of China”, in Dmitry Shcherbakov, editor, Advances in the Systematics of Fossil and Modern Insects, page 218:

psocid

Psocids (New 1987) are free-living insects that feed on microflora and organic debris on surfaces of vegetation or on other surfaces.[…]Psocids are frequently gregarious as nymphs or adults and may even group together under a communal web.

1993, Charles Leonard Hogue, Latin American Insects and Entomology, page 186:

The houe psocid, Liposcelis bostrychophilus, is a tropical species, but it occurs primarily in households in temperate regions.

2005, William H. Robinson, Urban Insects and Arachnids: A Handbook of Urban Entomology, page 367:

Nymphs and adults of psocids are regularly found in caves. Psyllipsocidae (in Europe the most common psocid in caves is Psyllipsocus ramburii) and Prionoglarididae are perhaps particularly characteristic of caves.[…]In the case of psocids, it has been suggested that the Psyllipsocidae (an ancient group) may have survived by avoiding competition with more recent forms by inhabitibg caves or similar habitats.

2008, John L. Capinera, editor, Encyclopedia of Entomology, volume 4, page 396:

(entomology) Any insect of the family Psocidae.


pulicid

We do not question the corollaries of Jordan's postulate, namely that vermipsyllid fleas never had ctenidia whereas comb-less pulicids and hystrichopsyllids are the descendants of comb-bearing fleas (Holland 1959).

1967, Bernice P. Bishop Museum Entomology Department, Pacific Insects, page 643:

These introduced pulicid fleas are cosmopolitan, having also been introduced by human transport to all continents except Antarctica (Lewis 1995).

2001, Diego P. Vázquez, Daniel Simberloff, “Chapter 6: Taxonomic Selectivity in Surviving Introduced Insects in the United States”, in Julie L. Lockwood, Michael L. McKinney, editors, Biotic Homogenization, page 114:

Two possible, not mutually exclusive, scenarios can be suggested. In the first, ancestors of the dipodine genus Jaculus dispersed to Africa (Black & Krishtalka, 1986) where they were presumably colonized by pulicids. In the second scenario, pulicids colonized jerboas switching from Gerbillinae which originated in Africa and dispersed to Asia no later than in the Miocene (Wessels, 1998).

2014, N. G. Ravichandra, Horticultural Nematology, Springer India, page 17:
