Genus Catalinia, gen. nov. (Scorpiones: Vaejovidae) is described from southern California, USA and Baja California, Mexico. The genus is composed of four species formerly placed in Pseudouroctonus: Catalinia minima (Kraepelin, 1911), comb. nov. (type species), C. andreas (Gertsch et Soleglad, 1972), comb. nov., C. castanea (Gertsch et Soleglad, 1972), comb. nov., and C. thompsoni, comb. nov. (Gertsch et Soleglad, 1972). Major diagnostic characters of Catalinia include a carapace with a very weak anterior indentation, a very stout metasoma with little or no tapering from segment I to V, and a mating plug with two partial bases. Evidence is presented suggesting …

A new vaejovid genus from Mexico, Franckeus, gen. nov., is described based on unique neobothriotaxy. Species placed in this genus are from the Vaejovis “nigrescens” group (previously called the “nitidulus” group). Six species comprise this new genus, distributed throughout Mexico (mainland as well as Baja California Sur): Franckeus nitidulus, F. rubrimanus, F. platnicki, F. minckleyi, F. kochi and F. peninsularis. A new species of the Vaejovis “nigrescens” group, Vaejovis davidi, sp. nov., is also described.

Ethological research has revealed that the vocal communications of birds are highly specialized behavioral adaptations that can shed light on evolutionary processes. The calls of the quails of the New World are a good example. This group of birds includes some thirty species, about half of which are limited to the tropical forests of Central and northern South America. The other species are North American, ranging as far north as southern Canada. Morphological evidence favors the view that the most generalized, or “primitive,” of these species are the tree quails of Mexico’s moist mountain forests. The more open-country and arid-adapted …
