description
Description Adult male with 64 podous rings, no apodous rings. Length 13 cm, width 7.6 mm. Adult females with 60 – 63 podous rings, no apodous rings. Length 13 – 14 cm, width 7.8 – 8.6 mm. Colour in life unknown; preserved specimens with head, antennae, legs, metazona, epiproct, paraprocts and hypoproct brown; prozona yellowish brown. GONOPODS (Fig. 7 A – E). Anterior coxal fold (ac; Fig. 7 A): lateral process (alp) regularly curved, terminating in sharp spine pointing slightly distad, with lateral short, sharp crest at middle of alp (Fig. 7 C, arrow); mesal process (amp) slightly shorter than alp, flattened, straight, directed distad. Posterior coxal fold (pc; Fig. 7 B) basally with moderately high lateral paracoxites (px), distally truncate, forming shelf for accommodation of telopodite, mesal process (pmp) triangular, directed distad, lateral process (plp) erect, digitiform. Telopodite (Fig. 7 D – E) leaving coxite over shelf of posterior coxal fold; femoral spine double, fe 1 very long, curved downward, situated above fe 2, in situ resting at middle of alp, fe 2 long, very slender, curved downward; tibial spine (ti) flattened, short, curving mesad; apical part: spatulate lobe (sl) small, rounded; with slender, long spine (sls) at base of apical part; palette (pa) simple, gutter-like, distally with about nine brownish blepharochaetae (bp). DNA barcode The GenBank accession number of the barcode of the holotype is KU 306521 (voucher code CUMZ-D 00088). Distribution (Fig. 12) Known only from the type locality.

diagnosis
Diagnosis A species of the opinatus subgroup. Differs from all other species in the subgroup by having the lateral process of the anterior coxal fold (alp) regularly curved, terminating in a sharp spine pointing slightly distad, and by having the tibial spine (ti) short and flattened.
etymology
Etymology The name is a Latin noun in apposition and refers to the flattened tibial spine (ti).
