Remarks

• Systematics: http://zoobank.org/4D4A2A7C-9239-4054-9F31-18EC93C1ADED The adult female of this species differs from those of all other currently described Andaspis species by having 6 tooth-like spurs (or minute horns) present on the anterior margin of the head. This species is somewhat similar to Andaspis halli Rao, 1952, a species known to occur in Zimbabwe. Adult females of the two species share an elongate body shape and a distinct second lobe. However, this species differs from it by the following characters (those for A. halli in parentheses): two scleroses located above each median lobe (no scleroses present above each median lobe), a club-shaped sclerosis present above each second lobe (an elongate sclerosis present above each second lobe), eight marginal macroducts located on the dorsum (six marginal macroducts located on the dorsum), and lacking perivulvar pores (three groups of perivulvar pores). (Hamilton, et al., 2017)
• Structure: Slide-mounted adult female 1.06 mm long; widest at third abdominal segment, 0.48 mm wide. Body outline oblong, derm membranous except for pygidium. A distinctive species with six spurs or minute horns present on anterior edge of head. Each antenna with five setae. Anterior spiracles each with 2 disc pores, each about 4 μm in diameter, trilocular; posterior spiracles lacking pores. Anterior abdominal segments well-developed with convex margins; tooth-like tubercles present on segments 2 and 4. In addition to those on pygidium, gland spines located along margins of abdominal segments 3 and 4. Many short macroducts distributed around ventral margins extending from mesothorax to abdominal segment 1. (Hamilton, et al., 2017)
