Type area.

French Guiana.

Diagnosis.

Larger size readily separates this species from A. puncticollis and A. gilvipes gilvipes .

Descriptive notes.

Data for SBL in Table 1. Habitus as in Fig. 5A. Both males and females with four terminal setae near the posterior margin on sternum VII.

Male genitalia. Fig. 6 A–C. Apical portion of phallic median lobe moderately long, broadly rounded in dorsal aspect, with prominent dorsal flange; endophallus without darkened microtrichial fields; lamina present, long and narrow, tapered but rounded at apex.

Ovipositor and female reproductive tract. Fig. 7A. Gonocoxite 2 (gc2) very thick, nearly straight. Bursa copulatrix (bc) moderately short; spermatheca (sp) long, tightly coiled, attached near the base of the common oviduct (co). Spermathecal gland duct originating above the base of the spermatheca, spermathecal gland (spg) small, sausage-like, small swelling of duct before gland.

Geographical distribution.

Fig. 8. The range of this species extends from Bolivia and central Brazil northeast to Surinam, and north to the island of Guadeloupe in the Lesser Antilles.

Chorological affinities and relationships.

Within Amblygnathus , the West Indian range of this species is overlapped only by the range of A. g. gilvipes . The putative adelphotaxon of A. cephalotes is the Brazilian A. gigas Ball and Maddison (1987: 265, Fig. 70D).

Material examined.

We have not seen any additional specimens other than those reported by Ball and Maddison (1987: 247).
