Avima tuttifrutti View in CoL sp. nov.

( Figs. 1-4 View Figure 1 View Figure 2 View Figure 3 View Figure 4 )

Diagnosis: Avima tuttifrutti sp. nov. can be distinguished by the presence of a green coloration on laterals and posterior margin of DS ( Figs. 1 View Figure 1 A-D, 2A, B); and area IV with a medial yellow hump ( Figs.1C, D View Figure 1 , 2B View Figure 2 ) (not present in other Avima species ); stylus of penis without dorsal process or dorsal keel ( Fig. 3 View Figure 3 ) ( Avima leucobunus Roewer, 1929 has dorsal keel).

Description: Based on male holotype (Measurements in Table 1).

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 ( Figs. 1A, C, D View Figure 1 , 2A, B View Figure 2 ). Area IV with a medial hump ( Figs. 1C, D View Figure 1 , 2B View Figure 2 ). Green coloration, except on laterals of cephalothorax and in the hump of area IV, in which is yellow ( Figs. 1A, C View Figure 1 , 2A, B View Figure 2 ). Ocularium low, without median concavity, with some granules. Mesotergum weakly delimited, divided into four areas with diffuse grooves, mostly smooth ( Figs. 1A View Figure 1 , 2A View Figure 2 ). Abdominal scutum widest at level of groove III. Area I-IV smooth with two medial subparallel granules. Area I divided in two halves; area II-IV undivided. Free tergites I-III with some granules ( Figs. 1A View Figure 1 , 2A, B View Figure 2 ).

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 View Figure 2 ). 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 View Figure 1 ).

Chelicera: Basichelicerite rectangular, with well-marked bulla; four tubercles on ectal face and two tubercles on

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 View Figure 2 ).

Pedipalps: Trochanter ventrally with two subapical tubercles. Femur with a ventroectal row of four setiferous

tubercles (the two basalmost larger than the others, and one medium ventromesal setiferous tubercle in the apical portion. Patella with one large mesal setiferous tubercle. Tibia ectal iIII, mesal IIi.Tarsus ectal IIi, mesal IIi ( Figs. 2E,F View Figure 2 ).

Legs: Leg I filiform, legs I-IV straight and smooth ( Figs. 1A View Figure 1 , E-F). Leg II unusually elongate and slender ( Fig. 1F View Figure 1 ). Distal portion of Fe II, Ti II and Ti IV with yellowish coloration. Leg IV thicker than the others; Fe IV length five times DS length ( Fig. 1E View Figure 1 ). Ta IV without tarsal process, claws smooth. Tarsal formula: ♂ holotype (ICN- Ao-1970): 10-9/13-17/7-6/7-7; ♂ paratype ( MNRJ 59051 View Materials ): 9-9/17-17/6-7/7-7 .

Penis: lamina parva (LP) small and depressed, apex crescent shaped, with anterolateral sharp corners dorsoapically pointed ( Fig. 3 View Figure 3 ). Malleus with two pairs of branched MS and one pair of branched MS B transversally aligned ( Figs. 3A, B View Figure 3 ); MS C absent; two pairs of MS D located in a keel between the ventral part of the LP and the base of the stylus ( Figs. 3A, C View Figure 3 ); MS E2 large and triffid, MS E1 absent ( Fig. 3A View Figure 3 ). Stylus elongated, (surpassing the LP), mostly straight, with sinuous distal half, tip truncated and straight ( Figs. 3B, C View Figure 3 ).

Color(in alcohol): Carapace,chelicerae,pedipalpi and legs I-IV background Burnt Sienna (#b04e0f) with reticulation

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 View Figure 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 View Figure 4 ), 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 View Figure 4 ), 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).

Type material: Male holotype (ICN-Ao-1970) and male paratype ( MNRJ 59051 View Materials ). Colombia, Córdoba department, Tierralta municipality, vereda Tuis Tuis, Reserva Natural Finca Tutti Frutti , [8.043333 -76.100306],[120 m], on ditch with mosses GoogleMaps ; 26.iv.2019; Raquel Pastrana leg.

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, 1996 and 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)).

A. tuttifrutti sp. nov. has a very long and slender leg II ( Fig.1F View Figure 1 ).Forcomparison,notethedifferencesintheproportion Leg II/DS length: A.bicoloripes (42 mm / 4 mm = 10.5); A. matintaperera (29.26 mm/2.48 mm = 11.8); A. soaresorum (31.93 mm/2.64 mm = 12.1); A. tuttifrutti sp. nov. (48.01 mm/2.61 mm = 18.4).

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 View Figure 3 ). 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 View Figure 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 View Figure 3 ). The MS A 2 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 View Figure 3 ). 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-D 2 in A. tuttifrutti sp. nov. ( Fig. 3 View Figure 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.
