Diagnosis: Lateral lamella of telocoxite with large median digitiform process directed distally, and with one to three small teeth below this (
Fig. 64
). First femoral process (
Fig. 63
,
fp1
) small, partially curved around the base of the larger spine and concealed in gonocoel. Second femoral process (
Fig. 63
,
fp2
) originating at knee, distally divided into 2 spines. Pectinophore ribbon-like (

,
pe
), and incurved towards spine branch, Spine branch narrow and apically acute (

Description:
Size
: Mid-body width in males
9 mm
, in females
11 mm
. Male with 48 segments, female with 49.
Colour
: Frons chestnut brown, head darker. Antenna chestnut brown, 6
th
antennomere darker. Collum dark brown; prozonites yellowish, dark yellow longitudinal stripes present at height of ozopores; metazonites dark brown to black, anteriorly lightly bordered; ozopores darker. Limbus yellowish. Last segment dark, only median ridge on paraprocts lighter. Sternites yellow, legs dark brown.
Head
: Frons finely wrinkled, with 5 supralabral pits. Epicranial suture distinct, interocular suture only faint. Suture from hind corner of eye visible, eye relatively close to antenna.Antennomere 2>3>4>5>1>6>7, and antenna hardly reaching posterior border of collum.
Collum
: Lateral margin wide, thickened, 1 or 2 folds at anterior and lateral borders.
Tergites and sternites
: Ozopores from 6
th
segment onwards. Prozonites longitudinally striated, ventrally turning into horizontal ridges of metazonites; metazonites with longitudinal striation, ending below ozopores. Prozonites and metazonites divided by a distinct suture. Limbus finely dentate. Sigilla ovoid.
Legs
: Pads becoming smaller posteriorly, on last segments only distal pad present, this always being larger than interior pad.
Gonopods
: As in diagnosis.
