Colouration uniformly dark brown, pronotum somewhat darker, legs and antennae pale brown.
Texture. Body semi-lustrous, all body parts rugulose, especially on head and thorax with numerous conspicuous, setigerous granules.
Vestiture. All body surfaces, including forewing veins densely covered with whitish semi-erect setae. Vestiture on dorsal surface of head erect, short, slightly directed anterad, setae on lateral and ventral surfaces contrastingly longer than those on dorsum, semi-erect, diversely directed. Posteroventral surfaces of forecoxae and foretrochanters each with a group of many prominent setae. Occurence of tr-setae (not studied in detail): dorsum and venter of head, ventral surface of labium; a few on lateral areas of pronotum, postero-ventral surface of foretrochanters, dorsal, posterior and ventral areas of forefemora, postero-ventral surface of foretibiae, a few on dorsal and ventral surfaces of mid- and hindfemora, dorsal surfaces of mid- and hindtibiae and tarsi.
Structure. Head (Figs. 9–13). Slightly longer than pronotum (Fig. 9). Anterior lobe elongate, ratio length of gena to its minimum width 0.91. Eyes medium-sized, dorsal ocular index 2.75. Ratio distance eye-apex of antennifer to length of eye 2.0. Post-ocular part of anterior cephalic lobe moderately long and moderately concave. Constriction between anterior and posterior cephalic lobes shallow. Posterior lobe transverse, without median impression (Fig. 10), ratio length to maximum width 0.74. Ocelli large, situated antero-laterally. Posteriormost area of lateral surfaces of posterior lobe of head with inconspicuously convex, narrow area lacking vestiture but with numerous, sparsely distributed non-setigerous granules (Figs. 12–13). Posterior lobe overlapping the junction with the neck but when seen in a dorsal view, its lateral outlines join the neck at an obtuse angle. Antennae slightly shorter than head and pronotum together (ratio 0.87), antennal formula (longest segment first) II, III, IV, I. Ratio basal width of segment II to its distal width 0.7.
Labium long, slender. Segment III three times longer than segment IV. Labial formula (longest segment first) III, II = IV, I.
Pronotum (Fig. 9). Collum with a shallow, broad triangular impression in the anterior third, posterior margin convex, precollum well developed, finely rugulose. Impression between collum and midlobe broad. Midlobe wide, widest near the middle, ratio width of midlobe to its median length 1.18. Midlobe with deep median groove, that terminates two-thirds of the way along in a shallow, broadly triangular impression. Posterior margin of midlobe convex, laterally with inconspicuous, indistinct impressions. Conspicuous and deep pronotal pits situated approximately half of length of midlobe, closer to lateral margin of midlobe than to linear groove. Two inconspicuous, very shallow pits situated close to linear (longitudinal) groove, either side of mid-line, half-way along midlobe of pronotum. Posterior lobe large, robust and long, lateral margins only slightly convex, irregularly rounded, widest in the posterior third. Posterior margin slightly convex, in the middle slightly concave. Ratio width to median length of posterior lobe 3.1.
Forelegs (Figs. 15–16). Forefemora stout, 3.4 times as long as wide, widest in the basal third. Foretibiae three times as long as wide, apex of foretibia protruding as a conspicuous process. Apicitibial armature consists of seven spiniform setae (Fig. 15), three ventral (middle one much longer, directed towards tarsus, anterior and posterior ones straight, shorter), two long subventral and two short, robust dorsal on upper-most part of tibial process. Bristle comb consisting of 38-40 setae. Foretarsi with armature consisting of four spiniform setae (Fig. 16), two long, slender proximal setae (anterior one longer) and two distal, shorter and stouter spiniform setae of the same length and shape. Apical section of ventral surface of fore-tarsus with group of five long setae (Fig. 16) situated between the spiniform setae of fore-tarsal armature. Posterior claw of posttarsus shorter, two-thirds the length of the anterior claw.
Mid- and hindlegs. Hindfemora robust, nearly twice as wide as midfemora, claws isomorphic. Apex of mid- and hindtibiae with two apical combs, the anterior comb consisting of approximately 12 setae on the middle and 10 setae on the hind tibia, the posterior comb consisting of 12 setae on the middle and 15–16 setae on the hind tibia.
Etymology. Named after the conspicuous granulosity of the body.
Micro-habitat and collecting method. All specimens (both adults and larvae) were collected by sifting of and subsequent extraction from in Winkler apparatus - leaf litter in rain forest in eastern Madagascar (Andasibe- Mantadia National Park).
Distribution. Eastern Madagascar.
Differential diagnosis. Proboscidopirates rugulosus sp. nov. differs from all other Proboscidopirates species by the presence of conspicuous setigerous granules on the head and thorax (Figs. 9–13), (the cuticle is smooth or has fine, inconspicuous granules in other species).
