ETYMOLOGY:
Hazara
is an old name of the region where the
type
locality is located. Noun in apposition.
DIAGNOSIS: Females are similar to those of
T. bangla
by the reticulated sternum, but are usually smaller, they have shorter lateral apodemes in the genitalia (fig. 52I), and have a more pronounced dorsal conical projection of the carapace (fig. 52F).
DESCRIPTION: Female (
holotype
, PBI_ OON 15665). Total length 1.98.
Cephalothorax:
Carapace orange, piriform in dorsal view, pars cephalica strongly elevated in lateral view, anteriorly narrowed to between 0.5 and 0.75 times its maximum width, sides granulate; lateral margin rebordered; nonmarginal pars cephalica setae light, in Ushaped row; nonmarginal pars thoracica setae absent; marginal setae absent. Clypeus vertical in lateral view, median projection absent; setae light, needlelike. Eyes: ALE circular, PME oval, PLE circular; posterior eye row straight from above, procurved from front; ALE separated by more than their diameter, ALE–PLE separated by less than ALE radius, PME separated by less than their radius, PLE–PME separated by PME radius to PME diameter. Sternum longer than wide, not fused to carapace, with radial furrows between coxae I–II, II–III, III–IV, surface reticulate, without pits, microsculpture covering entire surface, posterior margin not extending posteriorly of coxae IV, extensions of precoxal triangles absent, lateral margins with rounded extensions between coxae, orange; setae sparse, light, densest laterally, originating from surface. Mouthparts: chelicerae, endites, and labium pale orange. Chelicerae straight; fangs directed medially; setae light.
Abdomen:
Dorsum soft portions white. Book lung covers large, ovoid. Posterior spiracles connected by groove (fig. 52H). Pedicel ribbed. Dorsal scutum pale orange, covering full length of abdomen, no soft tissue visible from above. Postepigastric scutum pale orange, long, almost rectangular, covering about 3/4 of abdominal length. Setae of dorsum, and epigastric and postepigastric areas light, needlelike. Spinneret scutum with fringe of needlelike setae.
Legs:
Pale orange; patella plus tibia I shorter than carapace. Leg spination (all spines longer than segment width): leg I: tibiae v2-2-2-0, metatarsi v2-2- 0; leg II: tibiae v2-2-2-0, metatarsi v2-2-0. Trichobothria not examined.
Genitalia:
Rounded, small posterior receptacle visible through the cuticle, between two sclerotized ridges. Anterior sclerite T-shaped, lateral sclerites relatively short, with lateral additional extensions (fig. 52I).
