However, it is included here because two very similar species newly described below require an updated diagnosis, and because a few details were missing in previous studies. In addition, some specimens previously assigned tentatively to this species are now considered to belong to other species (see Distribution below).</p><p>Diagnosis</p><p>Leaf-dwelling, long-legged pholcid with dark pattern on carapace (Figs 1 – 2). Easily distinguished from most known congeners (except M. wayuu sp. nov. and M. uca sp. nov.) by strongly asymmetric male palps (Figs 3 – 4; including asymmetry of femur and tibia), by male chelicerae with pair of strong lateral protrusions (Fig. 5A), and by female external and internal genitalia (Figs 5C, 6 – 7; epigynum with posterior semicircular process, or ‘scape’; internal genitalia with complex system of pouches, ducts, and folds). Distinguished from both M. wayuu and M. uca by male chelicerae with rounded rather than pointed distal apophyses (Fig. 5A), by main branch of left procursus with distinctive ventral indentation (bold arrow in Fig. 4C), by hair-like process on right procursus (arrow in Fig. 4D), and by less pronounced palpal asymmetry, i.e., absolutely and relatively smaller right palp (e.g., right/left tibia diameter &lt;2.5 vs&gt; 2.6; see also Fig. 22). Further distinguished from M. uca by different color pattern on carapace (both in males and females; Fig. 2), by smaller size and shorter legs (e.g., male tibia 1 &lt;5.0 vs&gt; 6.5; female tibia 1&lt;4.0 vs&gt; 5.5), and by female external genitalia (epigynal scape without asymmetric groove; compare Fig. 6B with Fig. 16B).</p><p>Description (amendments; see Huber 2000, 2004)</p><p>Right procursus with hair-like process on retrolateral side (arrow in Fig. 4D). Prolateral trichobothrium absent on tibia 1, present on other leg tibiae. Female tibia 1 length (N = 50): 3.2 – 3.8 (mean 3.5). Shape of pore plates slightly variable (Fig. 7B, D).</p><p>Barcodes</p><p>We sequenced five specimens from two localities (geographic distance: 270 km) (Table 1; Fig. 23). Within localities, distances were 0.0%; between localities, distances ranged from 8.4 – 9.1% (Table 2). Distances to the other three species treated herein ranged from 15.5 to 20.2 %.</p><p>Distribution</p><p>Known from several localities in eastern Venezuela (Sucre, Bolívar) and northwestern Brazil (Roraima) (Fig. 24). The females from Falcón listed in Huber &amp; Villarreal (2020) are here assigned to the newly described M. wayuu sp. nov. (see below). Specimens from Peru listed and illustrated in Huber (2000) are considered to represent a distinct, formally undescribed species (or more than one species).</p></div>	https://treatment.plazi.org/id/5F0C87E2163BFFBEFE2AEA40FB6CFE5C	Public Domain	No known copyright restrictions apply.

Total body length 2.1, carapace width 0.7. Distance PME–PME 70 µm; diameter PME 90 ×110 µm; distance PME–ALE 30 µm; AME absent. Leg 1: 22.9 (5.7 +0.3+ 5.4+10.3 +1.2), tibia 2: 3.5, tibia 3: 2.1, tibia 4: 3.3; tibia 1 L/d: 77; diameters of leg femora (at half length) 0.09; of leg tibiae 0.07.</p><p>COLOR (in ethanol). Carapace pale ochre-yellow with distinct ochre-brown pattern on posterior half, ocular area and clypeus without dark marks (Fig. 1G – H); sternum mostly whitish, only posteriorly with small ochre mark; legs ochre-yellow, patellae and tibia-metatarsus joints dark brown; abdomen pale ochre-gray, dorsally and laterally with dark marks.</p><p>BODY. Habitus as in Fig. 1G – H. Ocular area slightly raised. Carapace without thoracic groove. Clypeus with short median process at rim (length ~30 µm). Sternum wider than long (0.56/0.44), unmodified. Abdomen approximately twice as long as wide, dorso-posteriorly pointed.</p><p>CHELICERAE. As in Fig. 19A; with series of ~16 – 19 modified (globular) hairs on each side and pair of distal apophyses near fang joints, without proximal lateral processes.</p><p>PALPS. As in Fig. 17; coxa unmodified; trochanter with short ventral apophysis; femur short, distally strongly widened, with short conical process on prolateral side, apparently symmetric; femur-patella hinges and tibia-tarsus hinges slightly shifted toward prolateral side; tibia short, slightly asymmetric (see below), with two trichobothria in relatively distal position; procursi strongly asymmetric, see below; genital bulb simple, with small conical process on prolateral side and long weakly sclerotized embolus ending with pointed process, slightly asymmetric (see below).</p><p>ASYMMETRY. Proximal palpal segments (coxa, trochanter, femur) apparently symmetric. Right tibia slightly thicker than left tibia (maximum diameter in lateral view ~220 vs 210 µm). Procursi directionally asymmetric (Fig. 18): left procursus with strong and distally sclerotized ventral hinged process, with slender prolateral sclerotized process, prominent dorsal hump, without distal sclerite; right procursus with slender and weakly sclerotized ventral hinged process, without prolateral sclerotized process, with smaller dorsal hump, with long distal sclerite directed towards ventral and prolateral. Genital bulbs weakly asymmetric: right embolus slightly longer than left embolus (~340 vs 310 µm).</p><p>LEGS. Without spines, without curved hairs, without sexually dimorphic short vertical hairs; retrolateral trichobothrium of tibia 1 at 7%; prolateral trichobothrium absent on tibia 1; tarsus 1 with ~20 pseudosegments, very indistinct.</p><p>Variation</p><p>Males</p><p>Tibia 1 in eight males: 4.8 – 5.9 (mean 5.5). Sternum in some males with small dark marks near bases of leg coxae.</p><p>Females</p><p>In general, very similar to male (including color pattern on carapace) but clypeus unmodified. Tibia 1 in two females: 4.5, 5.3 (missing in third female). Epigynum (Fig. 20A – C) very simple, weakly sclerotized, without scape; internal asymmetric structures visible through cuticle; posterior epigynal plate short and indistinct. Internal genitalia (Figs 19B, 20D – G) asymmetric, with sclerotized receptacle on right side connected with arched membranous structure on left side; the three examined females were same-sided; with pair of elongated pore plates (possibly slightly asymmetric, but this might be an artifact of preparation). One cleared female from Panama very similar but pore plate slightly longer (Fig. 21).</p><p>Barcodes</p><p>We sequenced two specimens from two localities (geographic distance: 173 km) (Table 1; Fig. 23). The CO1 distance was 0.6% (Table 2). Distances to the other three species treated herein ranged from 16.7 to 20.9%.</p><p>Distribution</p><p>Known from two localities in Colombia and one locality in Panama (Fig. 24).</p></div>	https://treatment.plazi.org/id/5F0C87E21629FFA5FDBEEF1CFBCAFCD8	Public Domain	No known copyright restrictions apply.
