Diagnosis

Redundant, genus monotypic.

Etymology

After ‘Hotel Dolichoiulus’, many years ago the author’s room in his parents’ house; subsequently the temporal home for several successive myriapodologists and others for shorter or longer periods.

Material examined (total 2 ♂♂)

Holotype TANZANIA • ♂; East Usambara Mts, Amani, Kwamkoro; ca 1000 m a.s.l.; 24 Dec. 1975; O. Lomholdt leg.; in rotten wood; NHMD 621699 .

Paratype TANZANIA • 1 ♂; East Usambara Mts, Tanga Region, Muheza District , Nilo FR ; 04°54′16″ S, 38°39′45″ E; 1090 m as.l.; 10 Jul. 2000; Frontier Tanzania leg.; NHMD 621700 .

Description (male)

SIZE. Length 53–61 mm, diameter 2.7–2.9 mm, 69–76 podous rings, no apodous rings in front of telson.

COLOUR. Specimen from Kwamkoro after 43 years in alcohol faded, but a clear dorsal pale stripe still visible; specimen from Nilo FR after 18 years in alcohol overall light to whitish brown, posterior part of metazonites amber, no dorsal stripe.

SUPRALABRAL SETAE. 4.

MANDIBULAR STIPES. With moderate disto-ventral lobe, distal margin hence bilobed.

ANAL VALVES. With moderate dorsal spine, no ventral spine or ‘corner’, margin raised, each with three setae on protruding ravelins.

LIMBUS ( Fig. 8E ). Strongly striate, margin with shallow lobes, one stronger ridge running into and through each lobe.

LEGS. With large ventral pads on postfemur and tibia from leg-pair 7 backward, diminishing in size and eventually disappearing toward hind end.

FIRST PAIR OF LEGS ( Fig. 7 ). Prefemoral lobes relatively short, broadly rounded in ventral view. Three coxosternal setae (CXS) close to lateral margin of coxosternum, well separated from prefemoral lobes. Prefemora with two mesapical setae (APS) and four to six peglike lateral sensilla (LPS).

STERNUM 9. Rounded-triangular (damaged during preparation, not illustrated).

GONOPOD COXA ( Fig. 8A–D ). Lateral margin forming a ca 120° angle, with a strong, obliquely distad spine (lcs) ca midway between angle and tip. Mesal margin of proplica (PP) with an indentation forming a similar angle, proplica hence almost parallel-sided though angled; proplical lobe hidden behind rounded metaplical flange. Metaplica (MP) without a differentiated basal flange, subapically with a rounded flange (rf) covering proplical lobe, apically with a strong, U-shaped spinelike process (msp), process first directed basad or latero-basad, then making a 180° turn and pointing distal or meso-distad. Posterior side of metaplica with a rounded, partly light-coloured, rounded knob (mk), just above with a small, rounded process (mrp) pointing basad-mesad.

GONOPOD TELOPODITE ( Fig. 8A–D ). Arculus 90º. Torsotope (TT) extended. A very long, retrorse, almost straight post-torsal spine (PTS) at end of not very pronounced post-torsal narrowing (PN). Solenomere (SLM) whiplike, almost completely concealed within telomere. Telomere (TM) taeniate, forming a sheath for the solenomere, with strong, hooklike basal spine (bts) on posterior side, distally curved posteriad-apicad and somewhat expanded into rounded ‘palette’ and with a straight spine (dts) on outer side of curvature.

Distribution and habitat

Known only from the forest around Amani in the East Usambara Mts, and from the Nilo FR slightly to the north of Amani, altitudinal range 930–1000 m a.s.l. See Doody et al. (2001) and Beharrell et al. (2002) for information on these areas.

Remarks

The basal telomeral spine (bts) in this species originates very close to where the basal solenomeral spine (BSS) originates in many other species, and it cannot be excluded that the spine in this species is in fact BSS.
