Type Material.— Holotype: S from Philippines, Luzon Island, Camarines Sur Province, 
Mt. Isarog, 11.2 km E Naga City, 13.663683, 123.371667, l-2.Jun.2011, elev. 1760 m, general col¬ 
lecting at night in forest, M. Yngente, N. Chousou Polydouri cols., preparation codes FML-01171- 
01172, (CASENT9043442), deposited in UPLB. 
Etymology. — The specific name is a noun in apposition for the volcano where the species 
was found: Mount Isarog. Isarog Agta is a nearly extinct Bikol language spoken by a semi-nomadic 
hunter-gatherer native people of the Philippines. 
Diagnosis. — Males of T. isarog sp. nov. can be distinguished from those of T. banahaw sp. 
nov. by the well-developed conductor that covers completely one of the hematodocha posteriorly 
(Figs. lA, 4F), whereas in T. banahaw sp. nov. the conductor does not cover it completely (Fig. 
2F). 
Description. — Male (Holotype, CASENT9043442): Total length 1.47. Prosoma: Length 
0.61, width 0.62, height 0.56. Sternum: Length 0.35, width 0.35. Eye diameters and interdistances: 
AME 0.08, PME 0.06, AME-AME 0.02, AME-PME 0.06, PME-PME, 0.03. Leg formula: 1243. 
Opisthosoma: Length 1.09, width 0.78, height 0.75. Dorsal shield of prosoma dark brown (Fig. 
4A). Sternum light olive-green circled by a dark line (Fig. 4C). Opisthosoma color overall olive- 
grey with numerous sparsely long, strong setae and a posterior tubercle (Fig. 4A-C), lighter gi'ey 
at tracheal spiracles and behind the anal tubercle (Fig. 4C). Epiandrum, booklungs and spinnerets 
tan (Fig. 4C). Femora and patellae olive-green, tibiae dark orange, metatarsi and tarsi tan (Fig. 
4A-C). Palp: cymbium with a ventral groove, conductor disk shaped and completely covering the 
hematodocha (Figs. 1 A, 4F), median apophysis minute and square (Figs. 1 A, 4F). 
Female: Unknown.
