A new jumping spider species of the genus Indopadilla Caleb et Sankaran, 2019 (Aranei: Salticidae) from the Central Highlands, Vietnam

Abstract

single sex only: i.e., five from the males and two from the females. To date, only one species, Indopadilla annamita (Simon, 1903) has been recorded from central Vietnam [Simon, 1903;Żabka, 1988; both sub Bavia].Recently, we performed several surveys of the spider fauna in the Chu Yang Sin National Park, Central Highlands, Vietnam and adjacent regions. As a result, a new jumping spider species -Indopadilla phantoani Hoang et Zhang, sp.n. -is described from the park based on both sexes. This is the second Indopadilla species found in Vietnam. Thus, with the addition of a new species from Vietnam, Indopadilla has become the largest genus of the tribe Baviini, with 15 species described to date. We have also provided a DNA barcode for the female of the new species for further studies. Materials and methodsSpecimens were hand-collected from foliage in the Chu Yang Sin National Park in Central Highlands of Vietnam. Legs II and III on the right side were cut out and preserved in absolute ethanol for DNA analyses, the remaining body was preserved in 70% ethanol for morphological examination. The specimens were examined with a Zeiss Stemi 508 stereo microscope (up to 100X magnification). Photos were taken using Jenoptik ProgRess CF Scan 12.5MP camera and Jenoptik ProgRes Capture Pro 2.10.0.1 software. The male palp and the female epigyne were examined and illustrated ABSTRACT. Indopadilla phantoani Hoang et Zhang, sp.n. (#$) is described from the Chu Yang Sin National Park, Central Highlands, Vietnam. A detailed description, illustrations of the copulatory organs and somatic features, and a distribution map are provided. A partial mtCOI-sequence for the female of the new species is also given.

High species diversity of Phintella and Phintella‐like spiders (Araneae: Salticidae) in Vietnam revealed by DNA‐based species delimitation analyses

“…Eight species of the genus Phintella were previously recorded from Vietnam (Żabka, 1985, Żabka, 2012, Peng and Xie, 1995, Kanesharatnam & Benjamin, 2019, Hoang et al, 2023. In the present study, 18 species of Phintella (Clade 3) were found.…”

“…In the current classification of Salticidae (World Spider Catalog, 2024), the following eight valid named species of Phintella have been recorded from Vietnam (Kanesharatnam & Benjamin, 2019;Peng & Xie, 1995;Żabka, 1985, 2012: P. accentifera (Simon, 1901); P. aequipeiformis Żabka, 1985;P. argenteola (Simon, 1903); P. bifurcilinea (Bösenberg et Strand, 1906); P. debilis (Thorell, 1891); P. daklak (Hoang et al, 2023); P. suavis (Simon, 1885); and P. vittata (Koch, 1846). A total of 121 Phintella and Phintella-like adult specimens collected in 19 localities of Vietnam, with an additional 43 DNA sequences (32 specimens) from Kanesharatnam and Benjamin (2019), were included as ingroups in our molecular phylogenetic analyses (Table S1; Figures 1 and 2).…”

Taxonomic notes on Indopadilla Caleb et Sankaran, 2019, with description of two new species from Vietnam (Aranei: Salticidae)

“…The tropical Asian jumping spider genus Indopadilla Caleb et Sankaran, 2019 is known to be the largest member of the tribe Baviini, accounting for 18 described species [World Spider Catalog, 2024]. To date, only three Indopadilla species have been reported from Vietnam, namely, I. annamita (Simon, 1903), I. cuc Wang, Li et Pham, 2023, and I. phantoani Hoang et Zhang, 2023[Simon, 1903Żabka, 1988;Caleb et al, 2019;Hoang et al, 2023;.…”
