A remarkable new species of Agoristenidae (Arachnida, Opiliones) from Córdoba, Colombia

A new species of Leiosteninae (Opiliones, Agoristenidae) from the Colombian Caribbean, Avima tuttifrutti sp. nov. García & Pastrana-M., is described and illustrated, based on two males from the montante forests of Tierralta (Córdoba department). The new species differs externally from other species of Avima by having one yellow hump on mesotergal area IV and green coloration on dorsal scutum. SEM images of the penis and a map showing its distribution are offered. This species represents the first record of a harvestman from the department of Córdoba and the eighth species of the subfamily recorded from the country.

Avima is the most diverse genus of the subfamily, with 34 described species, distributed from northern Brazil and Peru to Trinidad and Tobago and the Caribbean region of Venezuela (García & Villarreal, 2020: fig. 9), and has been considered as a non-natural aggrupation of species. Because of that, a cladistic analysis is needed for a better understanding of its phylogenetic affinities and real distribution (Porto & Colmenares, 2014;García & Villarreal, 2020). In Colombia, there is only one species of the genus recorded, Avima scabra (Roewer, 1963), from Cundinamarca department (central Andes).
As a result of a field trip to the buffer zone of Paramillo National Natural Park (Tierralta, Córdoba), a remarkable new species of Avima was collected. Here, we offer a description and illustrations of the species together with a distribution map. Terrestrial Eco-regions of the World (Olson et al., 2001). Geographic coordinates were interpolated between square brackets to indicate that they are estimates, using GoogleMaps. The word vereda refers to a subdivision of a municipality or village in Colombia and has no direct translation to English.

Avima tuttifrutti
Dorsum: DS epsilon type, with wrinkled tegument. Green coloration beginning at ozopore level and reaching the posterior margin of the scutum (except in the proximal half of mesotergal areas I-III and area V) and free tergites ( Venter: Coxa I with one anteroproximal large triangular tubercle with four cusps, a longitudinal curved row of nine medium-sized tubercles (the two distalmost visible in dorsal view) and two tubercles on the postero-distal margin (Fig. 2C). Coxa II with a row of tubercles on the distal third. Coxae III-IV with some granules. Coxa IV longer than coxa III stigmatic area with a few granules. (Fig. 1B).
Chelicera: Basichelicerite rectangular, with well-marked bulla; four tubercles on ectal face and two tubercles on  (Figs. 1A, 1B). Anterior region of hand with setiferous tubercles of different sizes, going from the middle of the hand to the base of movable and fixed fingers. Fixed finger with the inner surface finely grooved. Movable finger with one trapezoidal, medial tooth and with the inner surface at distal portion dentate (Fig. 2D).
Penis: lamina parva (LP) small and depressed, apex crescent shaped, with anterolateral sharp corners dorsoapically pointed (Fig. 3). Reddish Brown (#7f2b0a). Lateral borders of mesotergum, external region of areas I-IV and free tergites Vibrant Green (#0add08). Laterals of cephalothorax and medial protuber-ance of area IV Greenish Yellow (#cdfd02). Trochanter and femur of pedipalps, trochanters I-II, distal femora II and distal tibiae II and IV Banana Yellow (#fafe4b) (Fig. 1).  Distribution: Known from Tierralta (Córdoba department), at 120 m a.s.l., in the transition area between Magdalena-Uraba moist forests (NT0137) and Northern Andean Montane Forests (NT0145) WWF ecoregions (Fig. 4A), located in Serranía de San Jerónimo (San Jerónimo Mountains, West Andes). This area corresponds to the buffer zone of the Paramillo National Natural Park (Fig. 4B), one of the less studied and most endangered protected areas in the country, mainly because of the coca crops and cattle ranching activities (Clerici et al., 2020).

Etymology:
The specific name is a noun in apposition taken from the type locality, Tutti Frutti farm. It is property of Mr. Agustín Hernández, who makes huge efforts to maintain the forests of this place in the middle of the expansion of cattle activities.

Remarks:
The external morphology of Avima tuttifrutti sp. nov. (i.e., inconspicuous mesotergal grooves, lack of armature on mesotergal area III, presence (or not) of granules on DS), matches partially that of some species of Avima (e.g., Avima anitas Porto & Colmenares, 2014, Avima bicoloripes Roewer, 1949, Avima matintaperera Pinto-da-Rocha, 1996and Avima soaresorum Pinto-da-Rocha, 1996. However, the body coloration and the hump on area IV of the new species have not been seen in any Avima species, which easily allows its recognition as a new species. Additionally, the leg II and the penis of A. tuttifrutti sp. nov. show characters that deserve attention (for comparison, see Roewer (1949), Pinto-da-Rocha (1996 and Porto & Colmenares (2014)).
The stylus of A. tuttifrutti sp. nov. is very interesting, being mostly erect, becoming narrower from distal half and showing a sigmoidal tip (Figs. 3A, C). From the species cited above, just A. soaresorum has an straight stylus, but the tip is dorsally curved. The longitudinal dorsal keel is present in A. anitas and A. matintaperera, but is absent in A. tuttifrutti sp. nov. (Fig. 3) and A. soaresorum.
The MS E1 present in A. anitas are not present in A. matintaperera and A. soaresorum, nor in A. tuttifrutti sp. nov. (Fig. 3A). The MS A2 in A. tuttifrutti sp. nov. are located close to the base of the stylus, forming a belt around the malleus together with MS A1 and B (Figs. 3A, B). This alignment is similar to that seen in A. matintaperera and A. soaresorum, but opposite to that of A. anitas, where MS A2 are located far from the base of the stylus.
The presence of the MS D1-D2 in A. tuttifrutti sp. nov. (Fig. 3) is shared with A. anitas and A. matintaperera, but not with A. soaresorum.
All these morphological characteristics could suggest systematic affinities, but only a phylogenetic analysis including other Avima species and other Leiosteninae genera, would help to better understand its internal relationships.
