( Figs 1A–K View Figure 1 , 4A–C View Figure 4 , 5A, B View Figure 5 )
Material examined: Seventeen larvae from a single female:/ Namibia, 585/ Trans-Kalahari Highw. /-21.9030 16.38 075/19 & 25 Nov 2018 /leg. KEiB Expedition//Hopl.2Namib/712// KEIB _ DIP_01290 /
Pseudocephalon: Antennal complex (an) large, antennal dome (and) elongate with a tapered conical tip, antennal basal ring (abr) high ( Fig. 1A, B, D View Figure 1 ); maxillary palpus (mp) shaped as a slender conical protuberance, central cluster of sensilla situated at the tip, first sensillum basiconicum (sb1) very long and with slightly swollen tip, shifted away from the central cluster of sensilla and situated at about the middle of the palpus, additional sensilla coeloconica (ns1–ns2) situated dorsally at the base of palpus ( Fig. 1A, B, E View Figure 1 ); ventral organ (vo) on flat, fleshy lobe ( Fig. 1C View Figure 1 ); oral ridges (or) visible as long crevice running on lateral surface of pseudocephalon ( Fig. 1A View Figure 1 ); entire surface of pseudocephalon smooth without cuticular ridges or warts ( Fig. 1A–C View Figure 1 ).
Cephaloskeleton: Mouthhook (mh) large and strongly sclerotized, tip serrated with teeth oriented ventrally and slanting slightly posteriorly ( Fig. 5A View Figure 5 ); basal part with well visible lateral arm (la), mouthhooks tightly adpressed forming a gutter-like structure (Figs 4B, C, 5A, B); labrum (lb) large, long, and massive, about halfway along the length covered from above by a horseshoe-shaped sclerite (ahs) (Figs 4B, C, 5A), anterior half of labrum strongly curved downward (Figs 4B, 5A); intermediate sclerite (is) firmly fused to parastomal bars (pb) (Figs 4B, 5B); labial sclerite (ls) formed as a rod between mh and is (Figs 4B, 5A, B); parastomal bar short and broad (Figs 4B, 5B); vertical plate wide ( Fig. 4B View Figure 4 ); dorsal cornu very broad and slightly longer than ventral cornu ( Fig. 4B View Figure 4 ); dorsal bridge absent.
Toracic segments: Entire surface of thoracic segments (t1–t3) covered with cuticular scales, spinose bands not differentiated ( Fig. 1A, B View Figure 1 ); starting from t2, cuticular papillae (cp) visible as fleshy processes, tip of each process slightly widened and forming a crown-like structure ( Fig. 1F View Figure 1 ); Keilin’s organ with elongated sensilla ( Fig. 1I View Figure 1 ).
Abdominal segments: Entire surface of abdominal segments (a1– a7) ( Fig. 4A View Figure 4 ) covered with cuticular scales, spinose bands not differentiated ( Fig. 1G, H View Figure 1 ); lateral creeping welts (lcw) developed and also covered entirely by scales ( Fig. 1G View Figure 1 ); all abdominal segments (a1–a7) with cuticular papillae visible as fleshy processes with a crown-like structure like those on thoracic segments, each segment with the following arrangement of papilla: 1 ventro-laterally, 2 + 1 + 2 laterally, 3 + 3 dorsally ( Fig. 1G, H View Figure 1 ); ventral surface of a1–a7 with well-defined fusiform creeping welts (vcw) at the anterior margin of segments and post-crevice prolegs (pcp) at the posterior margin of segments ( Fig. 1H View Figure 1 ).
Anal division: Entire surface of anal division (ad) covered with cuticular scales, spinose bands not differentiated ( Fig. 1J View Figure 1 ); papillae around spiracular field in the form of fleshy processes as described above for thoracic and abdominal segments ( Fig. 1J View Figure 1 ); no hair-like spines around spiracular field ( Fig. 1J View Figure 1 ); posterior spiracle (ps) with four peristigmatic tufts (pt), each with three to four branches ( Fig. 1K View Figure 1 ); anal papillae (ap) rounded ( Fig. 1J View Figure 1 ); anal tuft with several small scale-like spines.
Remarks: Gravid females of Hoplacephala sp. were attracted to the stains from water sprinkled on the ground. Attempts to raise the first instar of Hoplacephala sp. on freshly killed blow flies ( Chrysomya albiceps (Wiedemann, 1819)) failed.
