Differential diagnosis

Differs from most species, except Paratropis otonga , in the morphology of the spermathecae, constituted by two receptacles with a long neck and fundus with lobes laterally extended ( Fig. 1E ). Differs from P. otonga in the spermathecae receptacles morphology without longitudinal fold and with fundus lobes laterally extended. Additionally, differs in the geographic distribution given that P. otonga is known from the Ecuadorian provinces of Cotopaxi and Pichincha while P. amfe sp. nov. is from Colombia, Quindio. Differs from P. chami sp. nov., described based on a male, by the absence of abdominal tubercles ( Fig. 1C ).

Etymology

The specific epithet is a noun in apposition taken from a combination of letters of the name of Ana María Fuentes Espagnolo, the partner of one of the authors (FPM) throughout numerous adventures.

Cheliceral furrow with two rows of well-developed teeth, 9/10 and 12/14 teeth on promargin and retromargin, respectively. Labium: length 2.14, width 1.98, with 84 cuspules on anterior edge. Labio-sternal groove with two lateral mounds. Maxillae longer than wide, with the anterior prolateral lobe very elongated, conical, with 102/113 cuspules spaced, largely spread over prolatero-ventral border from the inner edge to anterior lobe. Sternum: length 3.62, width 4.47; three pairs of sigillae, anterior subcircular, median and posterior sigillae oval; anterior and median sigillae marginal, posterior submarginal. Anterior edge of sternum with a semicircular area slightly elevated (joined to labio-sternal groove). Legs: cuticle not encrusted with soil particles. Leg and palpal segments measurements provided in Table 1 . Leg I clearly thicker than the others. Bristles, thorn-like setae and spines present. Trichobothria, filiform: Palp: Ti d7; Ta d7.
