Diagnosis
(redundant, genus monotypic)
Etymology
The name is a Latin noun meaning “remover of capsules”, cf. etymology of genus.
Material studied (total: 1 ♂)
Holotype TANZANIA: ♂, Morogoro Region, Kilombero District, Udzungwa Mts, Mwanihana Forest Reserve, near Sanje village, under rotten log in forest, K.M.Howell leg., KMH 1686 (VMNH).
Description (male)
SIZE. Length ca 6 cm, diameter 3.9 mm, 67 podous rings, no apodous rings in front of telson.
COLOUR. Specimen faded, traces of a broad, light dorsal stripe. Colour according to the collector’s field notes: “dark, shiny black with brown stripe length of back; legs pale”.
HEAD. Without peculiarities.
COLLUM. With a marginal and a submarginal furrow.
BODY RINGS. Almost perfect cylinders, not vaulted; suture straight; ozopores ca three diameters behind suture.
ANAL VALVES. Each with a short, curved dorsal spine and a small ventral denticle; marginal rim slightly raised, setiferous tubercles hardly protruding.
OZOPORES. Starting from ring 6.
LIMBUS (Fig. 7I). With simple, long-triangular lobes. Surface of lobes longitudinally microstriate.
MALE LEGS. With postfemoral and tibial ventral pads on legs, except a few anteriormost and posteriormost pairs, pads gradually decreasing in size towards posterior end.
GONOPOD COXA (Fig. 7 A–D). In anterior view parallel-sided, ca 4½ times as long as broad, subapically with a lateral triangular incision delimiting an apical lateral lobe (all). Proplica (pp) simple, parallel-sided; proplical lobe (prl) in anterior view hidden behind metaplical spine. Metaplica (mp) apically rounded, with a large mesal flange (mf) closing basal part of space between pro- and metaplica, subapically with a long basad spine (msp) covering proplical lobe and a stout, bifid process (mbp) on posterior surface.
GONOPOD TELOPODITE (Fig. 7 E–H). Arculus 90°. Torsotope (tt) simple, compact, without processes (Fig. 4B). Posttorsal narrowing without processes or spines. Telopodite just distal to posttorsal narrowing dividing into slender solenomere and broader telomere. Solenomere (slm) ca as long as and normally resting within concavity of telomere (projecting perpendicularly on Fig. 7E due to shrinkage during preparation for SEM), simple, apically with a stout hook and a subapical pointed lobe, in profile strongly reminding of a kind of bottle-opener (e.g., http://www.barleypop.com/best-beer-bottle-opener-period/). A long, slender, curved spine (ps) arising near base of solenomere. Telomere forming a curved, roughly parallel-sided trough, vaguely boat- or pod-shaped, with a subapical spike (tss) and several complicated lamellae inside the concavity (Fig. 7G).
Distribution and habitat
Known only from the type locality. Habitat: forest (under log).
Coexisting species
No other odontopygid species were found in the same sample as the unique holotype, but three are known from Mwanihana Forest Reserve: Chaleponcus mwanihanensis Enghoff, 2014, Aquattuor major Enghoff, 2015 and A. submajor Enghoff, 2015.
