• Kondo2010b: pp.9-10 ( Adult (F) ) [Key to the adult females of Cryptostigma Ferris]

Remarks

• Systematics: The adult female of C. saundersi can be diagnosed by the following features: (i) sclerotic pores absent, (ii) complex orbicular pores present, totalling 34, (iii) dorsal setae absent, except for those present on orbicular pores, (iv) preopercular pores absent, (v) each anal plate with about 21 setae on dorsal surface, (vi) with about 100 or more marginal setae between anterior and posterior stigmatic areas, (vii) 1 multilocular disc-pore present near each antenna, (viii) ventral microducts present in transverse linear intersegmental rows and around margin, and (ix) ventral tubular ducts present. C. saundersi appears closest to C. chacoensis, but the following features separate C. saundersi from C. chacoensis (character states on C. chacoensis in brackets): (i) 60 or more complex orbicular pores (22-33); a multilocular disc-pore present next to each antenna (absent); and ventral microducts present in rows (scattered). (Kondo, 2010b)
• Structure: Alcohol preserved specimens with a pale yellowish brown longitudinal stripe and several intertwining stripes on dorsum; also with semicircular stripes on declivity anterior to anal lobes; remainder of dorsum of a darker brown; a small darker brown to almost black area around anal plates. Ventral surface dark brown with a paler marginal area. Length (unmounted) approximately 7 mm, breadth from 5-6 mm (Laing, 1925a from Kondo, 2010b).
• Biology: According to its collector, L.G. Sanders, the insects were found in the trunk of an undetermined tree, and tended by ants of an undescribed species of the genus Azteca (Laing, 1925a).
• General Remarks: Description and illustrations in Kondo, 2010b.
