A new genus and two new species of oonopid spiders from Myanmar (Araneae, Oonopidae)

Abstract

A new genus, Promolotragen. nov., including two new species, P. hponkanrazisp. nov. (♂♀) and P. shankhaungsp. nov. (♂), is described from Myanmar. The new genus is similar to Molotra Ubick & Griswold, 2011 but can be distinguished by the completely fused bulb and cymbium, the presence of a receptacle, the absence of grooves connecting either the anterior or posterior pairs of spiracles, and the incised labium of both sexes.

A new genus and two new species of oonopid spiders from Tibet, China (Araneae, Oonopidae)

“…The As for the other Asian oonopid genera, i.e., Kachinia Tong &Li, 2018, andVientianea Tong &Li, 2013, also have heavily sclerotized abdominal scuta and leg spines. Paramolotra gen. nov. are quite different from both genera.…”

“…Oonopidae Simon, 1890 is a diverse spider family with 1884 extant described species in 114 genera (WSC 2021). They are small spiders (usually < 3 mm), generally living in leaf litter (e.g., Dupérré et al 2020), in canopies (e.g., Fannes et al 2008;Tong and Li 2011), caves (e.g., Chamberlin and Ivie 1938;Tong and Li 2013). Some are termite nest inquilines (Benoit 1964) or even ant-mimics (e.g., Platnick and Dupérré 2011;Sun et al 2019).…”

Two new oonopid spider species from Yunnan, China (Araneae, Oonopidae)

“…All measurements were taken using an Olympus BX51 compound microscope and are in millimeters. The terminology used in the text and figures follows Tong et al (2018) and Tong and Li (2020) . The type material is deposited in Shenyang Normal University ( SYNU ) in Shenyang, China (curator: Yanfeng Tong).…”

“…Currently, 125 oonopid species have been recorded in China, of which 37 species belonging to seven genera are known so far in Yunnan, China ( Tong and Li 2015a , b ; Liu et al 2019 ; Sun et al 2019 ; Tong et al 2019 , 2021 ; Huang et al 2021 ; WSC 2023 ). While studying new material we found two new species belonging to two genera that were not known previously from China; the two new species are described below.…”

A new species of Ischnothyreus Simon, 1893 (Araneae, Oonopidae) from Guangdong Province, China

“…Recently, a series of publications greatly increased the knowledge of the diversity of Ischnothyreus . Eight new species from Hainan ( Tong and Li 2008 , Tong and Li 2012 ), one new species from Taiwan ( Tong and Li 2014 ), one new species from Chongqing ( Tong et al 2018 ), one new species from Jiangxi ( Liu et al 2019 ), seven new species and one newly-recorded species from Yunnan ( Huang et al 2021 , Tong et al 2021 ) and three new species from Tibet ( Tong et al 2023 ) have recently been described from China. Up to now, 27 species of Ischnothyreus have been recorded in China.…”
