Caaeteboia new genus

Type-species: Liophis amarali Wettstein, 1930 ).

Etymology: Caa-etê- (Brazilian indigenous Tupi, “true forest”) + Boia (derived from the Tupi Mboi, “snake”), gender feminine.

Diagnosis: Small (much less than 1 m), slender snakes with slender transverse (maxillary) processes of premaxillae bearing a small additional process oriented posteriorly from each transverse process (these are in addition to the vomerine processes); hemipenis typically xenodontine, i.e., bilobed, semicapitate and semicalyculate; sulcus spermaticus divides on the proximal region; branches of the sulcus on the lobes with centrolineal orientation; lobes small, the medial lobe shorter than the lateral one; capitula ornamented with small, ill-defined papillate calyces, restricted to the sulcate and lateral surfaces of the lobes; hemipenial body ornamented with well-defined lateral enlarged spines and smaller spines covering the asulcate and sulcate sides of the organ out of the intrasulcar region; body spines decreasing in length toward the base.

Content: Caaeteboia amarali (Wettstein, 1930) new combination.

TRIBE PSEUDOBOINI Bailey, 1967 (Clade 46)

Pseudoboini Bailey, 1967: 157 .

Type-genus: Pseudoboa Schneider, 1801 .

Diagnosis: (99%, 21). A pair of pigmented spots on the palate; posterior region of the palatine bone longer than dental process, behind vomerian process; dorsal region of the vomer with a distinct process in which the ligament of the muscle retractor vomeris is attached; distinct maxillary process of the prefrontal forming a well defined articular area; lateral (nasal) process of the prefrontal hook-like; hemipenis bicalyculate and bicapitate; large lateral spines on the lobular crests; presence of a pair of calycular pockets within the lobular crotch of the hemipenis; enlarged lateral spines of hemipenis extending onto the lobular crests; lobular crests inflated (Zaher, 1994b, 1999).

Content: Boiruna Zaher, 1996 ; Clelia Fitzinger, 1826 ; Drepanoides Dunn, 1928 ; Mussurana new genus; Oxyrhopus Wagler, 1830 ; Phimophis Cope, 1860 ; Pseudoboa Schneider, 1801 ; Rhachidelus Boulenger, 1908 ; Siphlophis Fitzinger, 1843 .

Comments: We agree with Myers & Cadle (1994) and Ferrarezzi (1994a,b) in assigning authorship of the tribe Pseudoboini to Bailey (1967) instead of Jenner in Dowling et al. (1983; see Jenner & Dowling, 1985). Although Bailey’s (1967: 157; see also Bailey 1940) use of the name “ Pseudoboini ” was meant to be informal (“I call informally a tribe, Pseudoboini ”), he nonetheless defined the original concept of the tribe in a table on page 158 (without Saphenophis and Tropidodryas , which were included in this group by Jenner & Dowling, but which are not closely related; see Myers & Cadle, 1994, and Zaher, 1999).

Our analysis confirmed the polyphyletic nature of the genus Clelia already suggested by Zaher (1994b; 1999). We thus describe the new genus Mussurana to accommodate Clelia bicolor and two closely related species previously assigned to Clelia (Zaher, 1994b) .
