Dankittipakul, Pakawin, Tavano, Maria & Singtripop, Tippawan, 2012, Seventeen new species of the spider genus Teutamus Thorell, 1890 from Southeast Asia (Araneae: Liocranidae), Journal of Natural History 46, pp. 1689-1730 : 1709-1711

Teutamus calceolatus sp. nov.

( Figure 10 A–E)

Diagnosis

Teutamus calceolatus sp. nov. can be easily distinguished from its congeners by the rostrated tegulum of the male palp greatly extending retrolaterally ( Figure 10 A,C) and the sharply pointed submarginal lobes on the carapace; females can be easily recognized by the calceolus spermathecae with simple, curved ducts ( Figure 10 E).

Vock, 1♂ ( MHNG, M01-159) ; 7 July 2001, leg. A. Schulz and K. Vock, 1♂ ( MHNG, M01-160) .

Etymology

The specific epithet is a nominative form of an adjective (Latin: calceolatus , - a, - um = slipper-shaped), and refers to the shape of the spermathecae.

Spination: Leg I: Femora p1-1-1; tibiae p9 r9; metatarsi p5 r5. Leg II: Tibiae p8 r8; metatarsi p5 r4. Carapace orange-brown; submarginal lobes triangular, their apices sharply pointed. Sternum orange-brown. Legs hirsute, uniformly brown. Opisthosoma elongate-ovoid. Dorsal scutum covering two-thirds of length of opisthosoma.

Palp ( Figure 10 A–C): RTA triangular, rather short, strongly excavated anteriorly. DTA short and minute, broad at base, its apex blunt, directed ventrad. Tegulum rostrated, strongly protruding meso-retrolaterally, slightly excavated pro-apically. Conductor triangular, its apex sharply pointed. Embolic base well-developed.

Female (paratype, MHNG, M01-167). Total length 5.56; prosoma 2.48 long, 1.50 wide; opisthosoma 3.08 long, 1.52 wide.

Spination: Leg I: Femora p1-1-1; tibiae p9 r9; metatarsi p5 r5. Leg II: Tibiae p9 r8; metatarsi p5 r4. General appearance as in male; submarginal lobes triangular, their apices bluntly pointed; dorsum dark greenish; venter pale.

Genitalia ( Figure 10 D,E): Epigyne with widely separated circular copulatory orifices situated anteriorly. Insemination ducts slender, elongated, connected to middle portion of spermathecae. Spermathecae calceolus, provided with apical glandular pore. Fertilization ducts lanceolated.

Distribution

Known only from the type localities on the east coast of Malay Peninsula.
