Keys to Genera of Anthocoridae of America North of Mexico, with Description of a New Genus (Hemiptera: Heteroptera)

A key to the genera of Anthocoridae known from America north of Mexico is presented. A new genus, Alofa, is proposed for Cardiastethus sodalis White which is currently placed in the genus Buchananiella Reuter.

The Aquatic and Semiaquatic Hemiptera of Northern Florida. Part 4: Classification of Habitats and Keys to the Species

Many of the small streams in northern Florida may be classified in the sand-bottomed category. The water is swift and usually quite dark due to seepage and drainage from flatwoods and swamps. There is practically no vegetation associated with the stream proper. Twenty-four species of aquatic and semi-aquatic Hemiptera have been taken in this type of stream. The most typical are the gerrids and the rhagovelias. Gerris nebularis as well as one species of Rhagovelia are found only in swift-flowing sandbottomed streams and those of a calcareous nature. Microvelia alachuana is cQnfined to the sand-bottomed streams. Most of the aquatics have been taken only in areas where an accumulation of hyacinths have formed or in the small pools where the water is rather still and leaf debris has collected. Species present in sand-bottomed streams are:

A Key to the Nymphs of the Families of Hemiptera (Heteroptera) of America North of Mexico

A key is presented for the nymphs of the 41 families of Hemiptera (Heteroptera) found in America North of Mexico. The most important structures used for separation are the trichobothria and the dorsal abdominal scent glands.

A New Species of Rheumatobates from Florida (Hemiptera, Gerridae)

The new species, Rheumatobates crinitus, described below represents the first published record for the genus from salt water. The species was first collected in Lake Worth, Palm Beach County, Florida, by the writer in June 1947 and belongs to the group with unmodified antennae and hind legs. All of the other members of this group are known from outside the United States. They are R. clanis Drake and Harris, described from Rio Grande, British Honduras in 1932, R. minutus Hungerford 1936 from Yucatan, Mexico (Merida, Niagra Cenote), and R. vegatus Drake and Harris 1942 from the Isle of Pines, Cuba. The description of vegatus is quite short so it appeared at first that crinitus was that species. However, Dr. Carl J. Drake carefully compared three of my specimens with the single male type of vegatus and pointed out the differences to the writer. There is sufficient material in the three series of crinitus to show that the Florida form is distinct. In view of the constant differences in the proportions of the middle legs, slight differences in the number of hairs on the genital segment as well as the location of the black spines on the front legs of the male, I feel justified in according specific rank to the Florida form.

A New American Genus of Veliidae (Hemiptera)

The present paper was prompted by the discovery of an interesting addition to the veliid fauna of the salt marshes in southernmost peninsular Florida. This proved to be the species originally described as Microvelia turmatis by Drake and Harris (1933) from British Honduras. It was transferred by them later (1936) to Xiphovelia Lundblad, 1933, a genus whose type and only species was collected in Sumatra. Further study of the Florida material discloses that turmalis Drake and Harris is generically distinct from Xiphovelia ensis Lundblad, and it is here made the type of the new genus Husseyella. Husseyella belongs to the subfamily Microveliinae, which is characterized as follows: Ocelli absent. Tarsal formula 1, 2, 2; all claws pre-apical. Apical segment of middle tarsi not deeply cleft, and without plumose hairs arising from the base of such cleft. Hemelytra, when present, with four closed cells, not divided into distinct corium and membrane.

The Aquatic and Semiaquatic Hemiptera of Northern Florida. Part 3: Nepidae, Belostomatidae, Notonectidae, Pleidae and Corixidae

This paper completes the annotated lists of the families of aquatic and semi-aquatic Hemiptera of northern Florida; two families, Hydrometridae and Naucoridae, have been omitted. I published taxonomic and distributional notes on the family Hydrometridae in 1948 and no new data have been gathered. The family Naucoridae has been omitted as I am now undertaking a taxonomic revision of the genus Pelocoris. Part 4 of this series will include keys to the species and a classification of the northern Florida habitats.
