Description. Measurements: male holotype with 44 rings, circa 41 mm long, 3.2 mm wide. Male paratypes with 43 or 44 rings (specimen from Vevembe with 46), up to 44 mm long, up to 3.5 mm wide.

Coloration faded in alcohol. Head, legs and antennae orange-red ( Figs 39 View Figure 39 A–D). Anal valves and subanal scale reddish, preanal process greyish ( Fig. 39C View Figure 39 ). Metazonites red, remaining parts of body rings up to ozopore openings orange-reddish, more dorsally greyish. Specimens dorsally with a slender, orange line.

Head: each eye with circa 24–28 ocelli arranged in 6 or 7 vertical rows ( Fig. 39D View Figure 39 ). Labrum with standard three irregular teeth and a single row of 10–12 stout marginal setae. Clypeus with two setiferous foveolae on each side. Antennae long, protruding back to ring 6. Relative lengths of antennomeres: 1<<2=3=4=5=6, first antennomere very short ( Fig. 40A View Figure 40 ). Terminal antennomere with four large sensory cones located together inside a membranous area ( Fig. 40B View Figure 40 ). Antennomere 5 latero-apically with five rows ( Fig. 40C View Figure 40 ), antennomere 6 with two rows ( Fig. 40B View Figure 40 ) of sensilla basiconica.

Gnathochilarium lamellae linguales each with two standard setae located behind one another ( Fig. 39E View Figure 39 ). Stipites each with three apical setae. Palpi of gnathochilarium with numerous sensilla. Hypopharyngeal crest with a field of spine-like structures ( Fig. 40D View Figure 40 ). Central pads of endochilarium separated into two areas, a group of 6–8 sensilla located apically ( Fig. 40E View Figure 40 ). Close to endochilarium with a large group of sensilla, located towards hypopharyngeal crest. Mentum basally subdivided by a membranous suture ( Fig. 39E View Figure 39 ). Stipites each with a sclerotized ledge ( Fig. 39E View Figure 39 )

Mandible external tooth simple, rounded; mesal tooth with three cusps ( Fig. 40F View Figure 40 ). Seven to nine dense pectinate lamellae ( Fig. 40G View Figure 40 ). Intermediate area between pectinate lamellae and molar plate almost completely absent. Molar plate short, only slightly longer than pectinate lamellae, with only six or seven transverse furrows ( Fig. 40F View Figure 40 ).

Collum: smooth, not protruding as far as body ring 2 ( Fig. 39A View Figure 39 ).

Body rings: mostly smooth, with some irregular punctation and some transverse impressions on mesozona. Ozopores starting at ring 6, touching suture between mesozona and metazona. Ozopore on ring 6 located more ventrally than subsequent ozopores.

Telson: anal valves with well-developed lips and micropunctation. Preanal ring and subanal process well-rounded, not extending beyond anal valves ( Fig. 39C View Figure 39 ).

Legs: coxae 1 and 2 elongated and fused with sternum, podomeres from prefemur to tarsus in both sexes each with 4–10 ventral/mesal setae. Length of midbody legs circa 1.0 times body diameter in males ( Fig. 39F View Figure 39 ). Each podomere with a pair of setae ventrally. Coxae 3 and beyond of cylindrical shape. Tarsus with a stout dorso-apical seta and three pairs of setae, apical pair stout, others successively smaller ( Fig. 39G View Figure 39 ).

Male sexual characters: tarsal pads absent ( Fig. 39G View Figure 39 ). Coxae 3 and 4 each with a short, conical coxal process. Process protruding posteriorly ( Fig. 39B View Figure 39 ).

Anterior gonopod sternite elongated into a wide, almost rectangular lobe. Mesal process of coxite prominent, longer than telopodite, but shorter than telopodite process ( Fig. 41A View Figure 41 ). Telopodite on anterior side with a circular opening for the posterior gonopods ( Fig. 41A View Figure 41 ). Telopodite process very long, slender, slightly curved inwards. Shape resembling a sable ( Fig. 41B View Figure 41 ), basally projecting to lateral side into a long, slen- der, well-rounded, retrorse process. Retrorse process laterally extending beyond telopodite ( Fig. 41B View Figure 41 ).

Posterior gonopods unique ( Figs 41 View Figure 41 C–E). Gonopod pair connected via a wellsclerotized sternite. Coxites and telopodites positioned parallel to those of opposite gonopod. Coxite wide, well-sclerotized, with a single groove ( Fig. 41C View Figure 41 ). Coxite and telopodite separated by a suture. Telopodite massive, longer than and as wide as coxite ( Fig. 41C View Figure 41 ). Telopodite basally divided into two branches ( Figs 41D, E View Figure 41 ). Both branches of similar width and almost similar length, resembling a U ( Figs 41 View Figure 41 C–E). Sperm canal protruding at base of U, running free but somehow attached to lateral main branch ( Fig. 41E View Figure 41 ), tip prolonged into flagellum ( Fig. 41D View Figure 41 ). Mesal branch of telopodite on anterior side medially with a finger-shaped process ( Fig. 41D View Figure 41 ).

Female unknown.

Etymology: andringitra , noun in apposition, after the type locality, the Andringitra mountain massive.
