Carico — Spider Genus Tinus 
11 
Etymology. The name is from the latin noun for bear. 
Diagnosis. The length of the carapace, ranging between 3.5 mm 
and 3.9 mm, places its size, without overlap, between the smaller 
T. minutus and the remainder of the species which are larger. The 
epigynum is distinctive with a pair of oval atria. 
Description. Carapace : average length of females 3.63 mm (3.5- 
3.9 N=6); broad dark median band, narrow light submarginal bands; 
dusky marginal band. Legs’. (l-2)-4-3. Abdomen : median dark band 
without typical lateral, large indentations; narrow light bands within 
median dark bands converge posteriorly (Fig. 7). Epigynum: (Fig. 
30) lateral elevations in contact; median elevation widest posterior- 
ly, joined to lateral elevations, narrowed into an isthmus anteriorly 
which separates two large oval atria. Internal copulatory appara- 
tus: (Fig. 31) bursae copulatrix moderately broad, arises anterior- 
ly; fertilization tubes curved, relatively short. 
Natural History. According to Carlos E. Valerio, his field notes 
for collection number CEV-366 contain the following information: 
“. . . adult females rolled green leaves to use as retreats. These re- 
treats were found near the water (5-15 cm above water level). Many 
females had egg sacs at time of collection, holding them with the 
chelicerae against the sternum. Males were not found. Immatures 
(if the same species) had small webs located mainly in the holes of 
chewed up leaves . . .” (1976). A simple ovate-lanceolate leaf with 
serrate margins from an unidentified plant is in the collection jar. 
The leaf measures 4 cm X 10.5 cm and has the margins tied together 
to form a tube of 1 .25 cm in diameter. Debris in the retreat includes 
spiderlings and the appendages of a single damselfly (Caloptery- 
gidae). 
Distribution. Known only from the type locality. 
Material examined. Six females, seven juveniles. Males un- 
known.
