Remark. Unruh & Gullan (2008b) designated a lectotype for this species, provided diagnoses of the adult female and first-instar nymph, with a complete list of type material and a key to distinguish the adult female from all other species of the genus. Their diagnosis of the first-instar nymphs of C. abrahami was adapted from the original description because they did not have access to specimens of this instar. I recorded firstinstar nymphs associated with adult females and thus provide the first detailed description and illustration of the first-instar nymphs and adult females of this species. Recently, Kondo & Unruh (2009) published a photograph of live adult females of C. abrahami and included this species in their key to South American species of Iceryini.

ADULT FEMALE ( Fig. 2 View FIGURE 2 )

Description based on 8 females in fair condition.

Material examined. GUYANA: Syntypes females, 4 slides of Crypticerya abrahami Newstead, Issororo, N.W. Dist. British Guiana (= Guyana), 3.vi.15. Syntypes examined during a visit, 1986, to BMNH.

VENEZUELA: near Merida, 2000 m, on Calliandra falcata Benth. (Fabaceae) , November 2, 1984, I. Foldi coll., 4 adult females on 4 slides, and 5 first-instar nymphs on 1 slide. MNHN.

Mounted material: Body broadly oval, 5.6–5.9 mm long, 5.0– 5.2 mm wide; rounded at both ends. A good diagnostic feature for the adult female of this species is the presence of the long collared setae in a broad band around entire ventral submargin.

Dorsum. Derm rather thickened. Multilocular pores of 4 types: (i) each 9–10 µm in diameter, with a large triangular centre ( Fig. 2 View FIGURE 2 F) with 3 large inner loculi plus 3 pairs of outer loculi, evenly scattered across all body segments; (ii) larger pores, each 11–12 µm in diameter, with a large quadrilocular centre ( Fig. 2 View FIGURE 2 D) with 4 inner loculi plus 12 outer small loculi, densely scattered throughout; (iii) smaller pores ( Fig. 2 View FIGURE 2 A), each 8–9 µm in diameter, with 2 large inner loculi and a tiny subcentral loculus, plus 4 elongate outer loculi, present on head and thorax, and (iv) medium-sized pores ( Fig. 2 View FIGURE 2 K), each 8–10 µm wide, with a strongly sclerotised opening centre plus 8–12 outer loculi, abundant around anal opening.

Distribution. Colombia, Guyana, Venezuela.

Remarks. Three species, C. abrahami (Newstead) , C. pimentae (Newstead) and C. rosae (Riley & Howard) , belong in the Crypticerya rosae group of Unruh & Gullan (2008b), who considered these species to be morphologically identical. Unruh & Gullan did not synonymise them because they differ genetically and are found in different regions: C. abrahami in Colombia, Guyana and Venezuela, C. pimentae in Jamaica and C. rosae in Florida ( USA) and Mexico.

Crypticerya abrahami (Newstead) is rather similar to C. rosae (Riley & Howard) in that both females form neither an ovisac nor a marsupium and the secretion on the dorsal surface forms only a fine, thin coat; they also share broadly oval mutilocular pores with a bilocular centre, circular pores with a trilocular centre; multilocular pores with a bilocular centre with a central ductule; also the length of the marginal-submarginal hair-like setae is nearly the same (650 µm and 625 µm long). However, C. abrahami differs from C. rosae as follows: in the presence of pores with Y-shaped opening; in having multilocular pores with a circular centre and 10 outer loculi on anal area, and in the presence of numerous perispiracular thoracic pores.

In first-instar nymphs of C. abrahami, Newstead (1917) indicated 4 pairs of caudal setae, but in reality there are only 3 pairs (each 1.0– 1.2 mm long); the apparent median pair are much shorter and correspond to collared setae, of length about 600 µm, which is the same length as collared setae on the margin of the body. First-instar nymphs of C. rosae and C. multicicatrices also have 3 pairs of caudal setae, with maximum length of perhaps 1270 µm and 1100 µm, respectively. First-instar nymphs of C. abrahami differ from those of C. rosae in the presence of dorsal hexagonal pores and ventral quadrilocular pores. Also long marginal collared setae are distributed along the entire margin in C. abrahami , but only on the abdominal segments in C. rosae .
