A new species of Gymnophthalmus is described from the Llanos of Venezuela in Apure State. Gymnophthalmus marco-naterai sp. nov. is found mostly on sand dunes and is seemingly endemic to the eolic plains of Apure State. The new species differs from all other species of Gymnophthalmus with 13 scales around the midbody, by having distinctive coloration that includes complete and well-defined lateral and dorsolateral white stripes, a white ventral coloration in preservative (creamish white or yellow in life) devoid of dark markings, and salmon pink tail in life.

One of the most unusual results of intensive collecting in southern Manitoba in. 1958 was the discovery of this striking representative of a dominantly coastal genus of Ephydridae. It ivas collected at several times but in only the one locality, the Bald Head Hills, a region of active sand dunes in the largely stabilized, spruce-covered area representing the shores of the Pleistocene Lake Agassiz. The species is strikingly different from other species of the genus in its thoracic and wing pattern, hut in structural characters it is fairly typical.

The new species Salacia frutiplatensis is described and illustrated herein. This new taxon is part of the arboreal strata of the coastal sand dunes scrub of Los Tuxtlas, Veracruz, Mexico, where it is considered endemic. Salacia frutiplatensis is similar to S. elliptica, S. cordata, and S. impressifolia, but differs from these in the shape and diameter of the extra-staminal disk, pericarp thickness, greater number of seeds, and not displaying the lianous habit.

In the present study we provide evidence for the validity of the genus Trigonodactylus Hass, 1957, improve the diagnosis for this genus and describe a new species that belongs to it—Trigonodactylus persicus sp. nov., from the sand dunes in Khuzestan Province, southwestern Iran. The new species is closely related to Trigonodactylus [Stenodactylus] arabicus sensu Hass, and can be distinguished by the following morphological characteristics: small size, maximum SVL 34 mm; SVL/TailL—approximately 1:1; ventral scales roundish, weakly keeled, 54–61 longitudinal rows at midbody and 190–25 along midbody. No enlarged postmentals. Fingers and toes slightly flattened dorso-ventrally. Lateral edge of digits fringed by series of projecting triangular scales. No web between digits. No preanal and femoral pores. Dorsal color pattern formed by thin, dark, irregular vermicular patches and spots. Sometimes these dark dorsal patterns blend with each other and form transverse bands. There is a narrow, dark, longitudinal line between forelimbs and hindlimbs on lateral sides. Dark, well developed ʌ-shaped marking on snout, which continues behind orbit on tympanum region, approaches the upper ear opening and ends on the pectoral arch. Labial scales white, in some cases with grey-brown dots. Dorsal surfaces of limbs and digits with irregular dark bands. Dorsal surface of tail with 8–10 wide, dark brown bands with irregular margins, same size as alternating light bands. Ventral surface of body and limbs white, tail with dark spots that become more distinct posteriorly.

Lizards of the Liolaemus wiegmannii group comprise 11 species that are widely distributed east of the Andes, occurring in Argentina, Uruguay, and Brazil. Here we analyzed a population of the genus Liolaemus, found in the Pampa region of Uruguay, on isolated sand dunes along the Tacuarembó River. We conducted biometric, meristic, and genetic comparisons between this population and other populations of L. weigmannii from Argentina and Uruguay, and the other species of the L. weigmannii complex. Our morphological and genetic analyses showed that this population represents to a new species of the genus Liolaemus, belonging to the L. wiegmannii group. To date, its known distribution is extremely restricted.

A new species of dune cricket in the family Schizodactylidae, Schizodactylus salweenensis sp. nov. is described from Salween River, Mae Hong Son Province, northwestern Thailand based on both males and females. The Schizodactylidae is recorded for the first time in Thailand. The new species is most similar to Schizodactylus tuberculatus Ander, 1938 and Schizodactylus burmanus Uvarov, 1935 in the morphology of male subgenital plate, but mainly differs in the shape of subgenital plate apex, and the spurs of hind tibiae. The type series was collected from sand dunes along the river. This cricket reaches adulthood during the rainy season.

The diversity of nocturnal velvet ants (Hymenoptera: Mutillidae) at the Philip L. Boyd Deep Canyon Desert Research Center of southern California is investigated. Thirty-five species are found to inhabit areas on and around the canyon. Odontophotopsis hammetti, Sphaeropthalma chandleri, S. fergusoni, and S. mankelli are described as new species. Odontophotopsis hammetti and S. mankelli are only known from Deep Canyon. Sphaeropthalma chandleri and S. fergusoni also are known from Painted Canyon located in the Mecca Hills on east the side of the Coachella Valley and from Corn Springs located east of the Coachella Valley in the Chuckwalla Mountains, respectively. The females of too few of the species are known, so only the males are treated. A key is provided for the males. A new species-group, the S. fergusoni species-group is described to house S. fergusoni and the new species S. arnalduri, which is an apterous male described from Owens Lake Valley. Similarities between the fauna of Deep Canyon and the Algodones Sand Dunes are discussed.

The new species, Scaevola rialagartensis Cast.-Campos is described and illustrated from coastal shrubland and vegetation bordering mangroves in Rio Lagartos, Yucatan, southeastern Mexico, where it is considered endemic. The new species is similar to S. plumieri, S. taccada and S. wrightii, all of which grow in similar environments, but can be differentiated from these in the size of shrubs, shape of axes, and nerves along leaves.
