Bridging the distributional gap of Tyloridastriata (Thorell, 1877) and new synonymy (Araneae: Tetragnathidae).

Kulkarni S, Yadav S - Biodivers Data J (2015)

Bottom Line: Description of Tyloridastellimicans (Simon, 1885) mentions its identity with T.striata, which however characterizes sub-adult of T.striata and is accordingly synonymized.Tyloridastriata is newly recorded from India which links the distributional gap between China to Australia and Comoros Islands.Distributional and taxonomic records of Tylorida species with T.striata- like globose abdomen infer probable synonymy, which is subject to genus revision.

ABSTRACT

Background: Although Tyloridastriata has not been reported from India, observations on India Biodiversity Portal (IBP 2015), an open access repository for biodiversity information of Indian subcontinent, showed images resembling this species. The respective locality in Gujarat, India was explored and specimens were studied to confirm record of T.striata in India. Literature study showed some taxonomic lacunae which needed to be resolved.

New information: The tetragnathid spider Tyloridastriata (Thorell, 1877) is redescribed on examination of its long unknown syntypes from Kendari, Southeast Sulawesi deposited in the Natural History Museum of Giacomo Doria, Genoa, Italy and additional material from Kendari and other Indonesian regions. Description of Tyloridastellimicans (Simon, 1885) mentions its identity with T.striata, which however characterizes sub-adult of T.striata and is accordingly synonymized. Tyloridastriata is newly recorded from India which links the distributional gap between China to Australia and Comoros Islands. Distributional and taxonomic records of Tylorida species with T.striata- like globose abdomen infer probable synonymy, which is subject to genus revision.

Figure 1368205: Vulva, ventral view (Scale=0.3 mm)

Mentions: Carapace brown, sternum and legs fawn; trichobothrial sockets on proximal quarter length of femora IV. Abdomen yellowish brown with shiny guanine patches lined from apex towards ventral side, as also seen in live specimen (Fig. 2). Abdomen globose, roughly triangular in lateral view with two small tubercles at apex. Epigynal plate flat, 1.5 times wider than long, coils of fertilization ducts seen translucently (Fig. 1c).
