Description
Thyropygus ursus sp. nov.
urn:lsid:zoobank.org:act: D3E091F2-C075-458B-A9B5-DA35B673309B
Fig. 10 A–D
DiagnosisA species of the opinatus subgroup. Differs from all other species in the subgroup by having the lateral process of the anterior coxal fold (alp) flattened, broad, apically curved caudad and ending in a short spine, as well as by the first femoral spine (fe 1) being very short and erect.
EtymologyThe name is a Latin noun in apposition, meaning “bear”, and refers to the (somewhat) bearhead-like profile of the lateral process of the anterior coxal fold (alp).
Material examinedHolotype
THAILAND: ³, Krabi Province, Koh Lanta District, Lanta Islands, 7°39'20" N, 99°02'31" E, 2 Jan. 2009, leg. B. Däubl and E. Haring (NMHW-Inv.7855).
Paratypes
THAILAND: 1 ♀, same data as holotype (NMHW).
DescriptionAdult male with 62 podous rings, no apodous rings. Length 11 cm, width 6.4 mm. Adult female with 61 podous rings, no apodous rings. Length 12 cm, width 7.4 mm. Colour in life unknown; preserved specimens with head, antennae, legs, metazona, epiproct, paraprocts and hypoproct brown; prozona yellowish brown.
GONOPODS (Fig. 10 A–D).Anterior coxal fold (ac; Fig. 10A): lateral process (alp) flattened, broad, apically curved caudad, tip with short spine, lateral margin slightly folded; mesal process (amp) shorter than alp, slender, straight, directed distad, pointed. Posterior coxal fold (pc; Fig. 10B) basally with moderately high paracoxites (px), distally truncate, forming shelf to accommodate telopodite, mesal process (pmp) very small, directed distolaterad. Telopodite (Fig. 10 C–D) leaving coxite over shelf of posterior coxal fold; femoral spine double, fe 1 very short, erect, situated above fe 2, fe 2 very long, slender, curved downward, in situ resting behind alp; tibial spine (ti) long, slender, curving in horizontal plane, its tip close to base of fe; apical part: lamellar lobe (ll) broad, bent down; palette (pa) simple, gutter-like, with small crest (cr) near tip; distally with about twelve brownish blepharochaetae (bp).
DNA barcodeThe GenBank accession number of the barcode of the holotype is KU306523 (voucher code NMHW- Inv.7855).
