Amblygnathus gilvipes gilvipes Ball & Maddison, 1987: 230. HOLOTYPE male, labeled: Chapada, Brazil Acc. No.2966; Insect Collection CARNEGIE MUSEUM OF NATURAL HISTORY Pittsburgh, Pa. [yellow paper] (CMNH). ALLOTYPE female, labeled same as holotype (CMNH). 41 PARATYPES from various Brazil localities, Venezuela, Surinam and French Guiana, and Guadeloupe in the Lesser Antilles.- Ball 1992: 85.- Lorenz 1998: 356.- Lorenz 2005: 378.- Peck et al. 2014: 15.

Type locality.

Chapada, State of Bahia, Brazil.

Diagnosis.

This species is readily separated from the other two West Indian Amblygnathus species on the basis of small size and its range restricted to the Lesser Antilles.

Descriptive notes.

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

Male genitalia. Fig. 6 G–I. Apical portion of phallic median lobe shorter than in A. puncticollis , broadly rounded in dorsal aspect, with well developed but narrow dorsal flange; endophallus with one moderate sized spine and an extensive darkened microtrichial field nearly as long as the shaft. Ball and Maddison (1987: 230) reported, evidently incorrectly, that a long slender lamina was present. The male genitalia of three previously dissected specimens were checked for the lamina, but it did not appear to be present.

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

Geographical distribution.

Fig. 8. The known range of this subspecies extends from Rio de Janeiro in southern Brazil north to Manaus in western Brazil, to Venezuela, Surinam and French Guiana, and to the islands of St. Vincent and Guadeloupe in the Lesser Antilles.

Chorological affinities and relationships.

The West Indian range of this subspecies is overlapped by only the range of A. cephalotes . This subspecies is the putative adelphotaxon of the Peruvian A. gilvipes peruanus Ball & Maddison.

Material examined.

In addition to type material, we have seen a total of 4 specimens (3 males, 1 female). See Appendix for details.
