Cohonyx variegatus fasciatus: Conant, Amer. Mus. Novitates, 2205:6, January
29, 1965.
Remarks.—Only five specimens of Coleonyx have been collected
in Sinaloa. Edward H. Taylor found a specimen beneath a pile of
logs south of Presidio and referred it to Coleonyx fasciatus (Taylor,
1935b:203-05, 1938:517; Klauber, 1945:182-84, 205). A second
specimen (UIMNH 57847), collected at night on the highway in
the same area, exhibits the coloration typical of C. fasciatus. Three
other specimens are known from north of Culiacan; two were
taken at night on the road and a third (SU uncataloged) was found
beneath a rock. Conant (1965:4-6) considered his specimen
(AMNH 87617) to be intermediate between C. variegatus sonoriensis
and C. fasciatus and accordingly reduced fasciatus to subspecific
status. The other two lizards from the same area confirm his
findings.
Distribution in Sinaloa.—Probably throughout the lowlands of
the state. See Fig. 39,
Specimen examined.—11 mi. S Guaimichil (CSCLB 2002).
Literature records.—18 mi. NW Culiaean (Conant, 1965:4); 10 mi. S Presidio
(Klauber, 1945:182; Smith and Taylor, 1950b:43; Taylor, 1935b:203).
Additional records.—7.4 mi. S junc. hwy. 15 and 40 (UIMNH. 57847); 21
mi. N Rio Culiac&n [hwy. 15] (SU uncataloged, field number FWB 2140).
Gehyra mutilata (Wiegmann)
Peropus mutihtus Wiegmann, Nova Acta Acad. Leop.- Carol., 17:238,
1835 (type locality, Manila, Philippine Islands).
Gehyra mutilata: Boulenger, Catalogue Lizards Brit. Mus., 1:148, 1885.
Remarks.—Two females agree with the re description by Smith
and Necker (1943:197-99) based on one adult and one juvenile of
undetermined sex. The snout-vent lengths are 48, 56; tail 50, 33
(partially regenerated); supralabials 7/7, 8/8 to center of eye; infralabials
7/7 to center of eye. Both specimens were captured from
the side of a building on June 4, 1962. The name Gehyra mutilata
is used following Boulenger (1885a: 148) and Bustard (1965:260).
Gehyra mutilata has been introduced into western Mexico at
several seaport towns. The climbing ability and secretive habits of
these lizards make them likely candidates for stowaway transport
with ship cargos. The original colonists probably came from the
Philippine Islands (Taylor, 1922:64). These lizards are seen in
abundance at night throughout the older parts of Mazatlan. Specimens
were found by careful searching of walls and buildings along
the beach front. Individuals are especially plentiful around lights
where they feed on insects attracted to the light.
