TEUIA , NEW GENUS

TYPE SPECIES: Teuia beckeri , new species. ETYMOLOGY: The generic name honors the

Kaiová Indians (also called Teui), a group of Amerindians who number more than 1000 people scattered in villages and government Indian posts throughout southern Brazil. They are thoroughly integrated into neo-Brazilian society. Gender feminine.

DIAGNOSIS/DESCRIPTION: See diagnosis and description of single known species below.

GENERIC RELATIONSHIPS: The general shape of the male palp (huge femur, relatively small tibia) is similar to some representatives of Mesabolivar (e.g., M. huambisa , locono ; see figs. 742, 753) and Otavaloa (e.g., O. angotero ; see fig. 1236). Otherwise, the phylogenetic position is obscure (apart from the inclusion in the New World clade: male palpal coxa with retrolateral apophysis, large distance PME-ALE).

DISTRIBUTION: Known only from type locality in southern Brazil.

Teuia beckeri , new species Figures 1259–1264

TYPES: Male holotype, 1♀ paratype from São Leopoldo, Rio Grande do Sul, Brazil, Nov. 8, 1974 (C. J. Becker), in MCN (2357).

ETYMOLOGY: Named for the collector of the type material.

DIAGNOSIS: Eight-eyed pholcid with globular opisthosoma and relatively long legs; distinguished from all other known pholcids by the massive procursus that is partly wrapped around the embolar division (fig. 1260); also by the two pairs of apophyses on the male chelicerae (fig. 1262).

MALE (holotype): Total length 2.3, carapace width 1.06; leg 1: 17.8 (4.5+0.4+4.7 +7.1+1.1), tibia 2: 3.8, tibia 3: 2.4, tibia 4: 3.5; tibia 1 l/d: 51. Prosoma shape and eye pattern similar to Mesabolivar togatus (cf. fig. 853); distance PME-ALE about 90% of PME diameter. Carapace ochre-yellow, with dark median line and spot behind ocular area; ocular area and clypeus slightly darker, sternum light brown with yellowish specks, labium darker. Chelicerae with two pairs of short frontal apophyses (fig. 1262), lateral pair projects forward, median pair faces downward. Palps as in figs. 1259–1260, with distinct retrolateral coxal apophysis, femur very large, proximally with retrolateral protrusion; procursus large and massive, partly wound around embolar division (fig. 1260); bulb simple, with unsclerotized embolar division (fig. 1261). Legs ochre-yellow, without dark or light rings; femora 3 slightly thicker than others; without spines, without curved and vertical hairs; retrolateral trichobothrium of tibia 1 at 5%; tarsus 1 with ~ 17 pseudosegments. Opisthosoma almost globular, ochre-green, with dark greenish spots; genital plate wide, ochre.

FEMALE (paratype): Total length 2.9, carapace width 1.06; tibia 1: 3.4. Very similar to male, but with dark rings distally on femora; opisthosoma higher than long (2.5 versus 2.0). Epigynum light brown with blackish arch frontally (fig. 1263); internal genitalia as in fig. 1264. (I could not find pore plates.)

DISTRIBUTION: Known only from type locality.
