Diagnosis.
Mesotergal area III with large paramedian spines (the remaining species of Paravima , except P. morritomacairensis , without ornamentation or with conical, mammilliform or domed tubercles). Can be distinguished from that species by the coloration of mesotergal areas I-IV darker than the rest of the DS (concolorous in P. morritomacairensis ).
Description.
Holotype (ICN-Ao-1671.1). Measurements: CL: 0.8, AL: 1.6, CW: 1.6, AW: 2.1, BaCh: 0.3, IOD: 0.5; Pedipalp: Tr: 0.4, Fe: 0.5, Pa: 0.5, Ti: 0.5, Ta: 0.5, Claw: 0.4; Leg I (Tr: 0.3, Fe: 3.8, Pa: 0.6, Ti: 2.5, Mt: 4.7, Ta: 1.5); Leg II (Tr: 0.4, Fe: 8.7, Pa: 0.9, Ti: 7.0, Mt: 8.7, Ta: 3.3); Leg III (Tr: 0.5, Fe: 6.8, Pa: 1.0, Ti: 3.6, Mt: 7.4, Ta: 1.7); Leg IV (Tr: 0.7, Fe: 9.7, Pa: 1.1, Ti: 5.0, Mt: 10.8, Ta: 2.6). - Dorsum: Anterior and lateral margins of DS smooth. Ocularium smooth (Figs 7B View Figure 7 , 8A View Figure 8 ). Mesotergum delimited, darker than the rest of the DS, divided into four areas, with some granules. Area I divided into two halves, each one with a pair of tubercles; area II-IV undivided; II with a pair of medium-sized tubercles close to the medial axis of the body (Figs 7B, C View Figure 7 , 8A View Figure 8 ); III with a pair of high paramedian spines (Figs 7C, E View Figure 7 , 8A, B View Figure 8 ); IV with four small tubercles. Posterior border of scutum substraight, with a row of tubercles. Free tergites I-II and anal operculum with a few tubercles (Fig. 8A View Figure 8 ). - Venter: Coxae I-IV with some granules (Fig. 7D View Figure 7 ). Coxa I with a longitudinal row of tubercles at the medial region, being the third larger than the others, three large tubercles reaching the anterodistal region, and one small tubercle close to the posterodistal margin (Fig. 8C View Figure 8 ); coxa II longer than coxa I; coxa III longer than I and II; coxa IV backward projected (Fig. 7D View Figure 7 ). Sternites and anal operculum with a few small tubercles. Stigmatic area smooth. Stigmata large, oval and transverse (Fig. 7D View Figure 7 ). - Chelicerae: Segment I rectangular, with well-marked bulla (Fig. 7B, C View Figure 7 ), two small ectal subdistal tubercles, and two separated tubercles on the proximal border (Fig. 7B View Figure 7 ). Chelicera not swollen, monomorphic (Figs 7C, E View Figure 7 , 8A View Figure 8 ). Hand with some sparse setiferous tubercles of different sizes on the frontomesal region, a group of setae on the mesal face of the fixed finger, and some setiferous tubercles close to the base of the fixed finger (Fig. 8D View Figure 8 ). Fixed finger with the inner surface irregularly dentated. Movable finger with one trapezoid, sub-basal tooth and with the inner surface dentate (Fig. 8D View Figure 8 ). - Pedipalps: Longer than DS length, smooth. Tr ventrally with two subapical tubercles. Fe with a ventromesal row of six setiferous tubercles (the second and the third larger than the others), and one large ventroectal setiferous tubercle in the distal portion (Figs 7C View Figure 7 , 8E View Figure 8 ). Pa with one large mesal setiferous tubercle. Ti ectal II, mesal iII. Ta ectal IIi, mesal IIii (Fig. 8E View Figure 8 ). - Legs: Legs I-IV smooth. Leg I filiform, the rest, getting steadily thicker from leg II to IV. Fe IV four times DS length (Fig. 7A View Figure 7 ). Tarsal counts: 7(3)-8(3)/18(3)-18(3)/7-7/7-7. - Penis: LP short and depressed, half-moon shaped, with anterolateral blunt corners apically pointed (Figs 8F-H View Figure 8 ). Malleus carrying the branched MS-A-B (two pairs of MS-A and one pair of MS-B in a diagonal alignment) (Fig. 8H View Figure 8 ). MS-D1-2 short, located in an oblique line on a keel between the LP and the base of the stylus (Fig. 8G, H View Figure 8 ). MS-E2 medium-sized and branched (Fig. 8F View Figure 8 ). Stylus straight, surpassing the lamina parva, tip truncate (Fig. 8H View Figure 8 ). - Color (in ethanol): Carapace reticulated dark brown (59) on light orange yellow (70). Mesotergum dark brown (59). Pedipalps and chelicerae deep yellowish brown (75). Posterior border and free tergites Dark Olive (108). Legs I-IV dark yellowish brown (78).
Remarks.
The coloration in vivo (Fig. 19G View Figure 19 ) is quite different, with carapace, chelicerae, pedipalps, coxae and trochanters strong reddish brown (40); laterals of DS vivid orange yellow (66); mesotergum and medial region of free tergites brownish black (65); free tergites vivid yellow green (115); and the rest of the legs brownish black (65). - Female: Chelicerae of the same size as male (monomorphic). Femora slightly thinner than in male.
Derivatio nominis.
The species name honors professor Eduardo Flórez, curator of the ICN Arachnological collection. Professor, in Latin magister, ( Paravima magistri in genitive case), in recognition of his excellent work in the teaching and development of arachnology in Colombia and his interest in the divulgation of scientific knowledge about the arthropods in the country.
Distribution.
