A morphological cladistic analysis, consisting of 45 terminals and 58 characters was performed to evaluate the monophyly of the genus Paravima Caporiacco, 1951, and its relationship to other Leiosteninae. The analysis resulted in two most parsimonious trees, all recovering Paravima as monophyletic with the inclusion of two species formerly described in Avima Roewer, 1949, therefore, the following nomenclatural acts are herein proposed: Paravima plana (Goodnight & Goodnight, 1949) comb. nov., and Paravima quirozi (González-Sponga, 1981) comb. nov., Avima vigirima (Villarreal-M & Rodríguez-Manzanilla, 2003) is here considered as a junior subjective synonym of P. quirozi (González-Sponga, 1981) comb. nov., Paravima acanthoconus Villarreal-Manzanilla & DoNascimiento, 2005 is here considered as a junior subjective synonym of Paravima propespelunca González-Sponga, 1987, and Paravima flumencaurimarensis González-Sponga, 1987 is here considered as a junior subjective synonym of Paravima goodnightorum Caporiacco, 1951. Additionally, three new species are described: P. lokura sp. nov. (Tamá National Natural Park, Norte de Santander department) and P. magistri sp. nov. (Los Tunos Natural Reserve, Cundinamarca department), both from Colombia; and P. totoro sp. nov. (Henri Pittier National Park, Aragua state) from Venezuela. Finally, an emended generic diagnosis, a key for all the species, and a distributional map are presented.

The Neotropical family Agoristenidae Šilhavý, 1973, is an uncommon albeit diverse taxon (26 gen., 80 spp.), as is reflected for the small number of specimens deposited in natural collections, divided into three subfamilies, the most diverse being Leiosteninae Šilhavý, 1973, from northern South America (13 gen., 62 spp.) (
Paravima, as currently diagnosed, is a small group of six species associated with forests in the central region of the Cordillera de la Costa in Venezuela. The genus was described by
On the other hand, Avima is the most diverse genus of Leiosteninae, however, it is most likely an amalgam of unrelated lineages as partially suggested by
In the present work, a phylogenetic analysis based on morphological characters was carried out. The monophyly of Paravima was tested and the relationship between the three previously mentioned Avima species and the genus Paravima was evaluated. So, after two new combinations, three synonyms, and the description of three new species, the genus Paravima passes from six to nine species, all of them included in an identification key and an updated geographical distribution map.
Individuals of the species were imaged from varied sources. We mostly used a Nikon 5200, a Canon PowerShot S3IS, and a Sony Cybershot DSC-V1 camera attached to a stereomicroscope. Multiple images of each selected specimen at different focal planes were combined with Zerene Stacker of CombineZP (
The male genitalia illustrated with Scanning Electron Microscopy (SEM) was dehydrated with Critical Point Drying (CPD), sputter-coated with gold-palladium, and examined with a JEOL JSM-6390LV Scanning Electron Microscope at the Center for Scanning Electron Microscopy of Museu Nacional de Rio de Janeiro (MNRJ), with an accelerating voltage of 10 kV. Drawings were made using a stereomicroscope with camera lucida, and digitized with Inkscape 0.91 software. Some penis drawings have no scale. Color descriptions use the standard names of the 267 Color Centroids of the NBS/IBCC Color System as named in
The distribution map was made with Quantum GIS 2.18.19 software (

We obtained two parsimonious trees, using a value of K = 6.4844 whose strict consensus is presented in the figure 16 (L=189, CI=43, RI=73). Paravima was recovered as monophyletic, grouping all the previously described Venezuelan species, plus the species Avima plana and A. quirozi, together with the species described here, Paravima lokura sp. nov., P. magistri sp. nov., and P. totoro sp. nov. A sister group relationship between Avima venezuelica and Paravima was found under the following values of K: 2, 4, 6,4844 and 8 (Figs
Paravima
Paraavima (incorrect subsequent spelling): Soares & Avram 1981: 76.
Paravima goodnightorum Caporiacco, 1951, by monotypy.
Originally in Tricommatinae. Transferred to Leiosteninae by Soares & Avram (1981).
The genus can be diagnosed within Leiosteninae by the placement of the ocularium, located close to the anterior half margin of the carapace and the absence of a longitudinal dorsal keel in the stylus of the penis, and additionally by the combination of characters presented in the description.
DS outline Epsilon type 3, with posterior border distinctly wider than anterior border, giving an ovoid appearance. Ocularium low, very close to the anterior margin of DS, smooth (granulate in P. lokura sp. nov.), and with median concavity. Interocular distance half of carapace width (except in P. magistri sp. nov. that is one third). Mesotergum concolor with the rest of the DS (except in P. magistri sp. nov., P. plana comb. nov., and P. quirozi comb. nov., with a dark spot). Mesotergal area III with paramedian ornamentation (except in P. plana comb. nov. and P. quirozi comb. nov., smooth). Long legs (FeIV length at least 3.7 times DS length). Penis with tips of LP sharp, not differentiated and not curved; subdistal depression between MS-E2 and horned LP; malleus with three pairs of branched MS-A (except in P. magistri sp. nov. where it has two pairs); MS-C and MS-E1 absent; stylus sinuous (except in P. magistri sp. nov., P. plana comb. nov., P. quirozi comb. nov., and P. totoro sp. nov., where it is straight), and without dorsal keel or process.
From Greek παρά (beside) and the pre-existing genus Vima. Gender: feminine.
Venezuela: Cordillera de la Costa mountain range (Distrito Capital, Aragua, Carabobo, Miranda, Guárico and Yaracuy states); Colombia: P.N.N Tamá (Norte de Santander department) and San Antonio del Tequendama (Cundinamarca department).

The differences in shape and size of the dark spot in the mesotergal areas of P. quirozi seems to be populational: specimens from Maimire (Yaracuy) have more rounded spots, individuals from La Guáquira (Yaracuy) exhibit wider and shorter spots (Fig.
Mesotergal area III with paired dome-shaped tubercles (the remaining Paravima varies between acute spines, conical/mammilliform tubercles, or lack of tubercles). DS variegated, with mesotergal areas II–III darker in the center and gradually fading towards the laterals (in P. magistri sp. nov. variegated in the anterior region of DS; in the other Paravima species uniformly variegated).

Paravima totoro sp. nov. (
Totoro is a character in the Japanese animated fantasy film My Neighbor Totoro (directed by Hayao Miyazaki and animated by Studio Ghibli), being a friendly wood spirit in post-war rural Japan. For us, the paramedian armature of the new species resembles the ears of the charismatic Totoro. We take advantage of exalting the excellent work of Studio Ghibli with this tribute.

The monophyly of Paravima has not been previously tested in a phylogenetic context, with former analyzes including a single species of the genus (
In the present analysis, we found that character (S1) defines a derived group within Paravima, and occurs homoplastically in Avima tuttifrutti. Additionally, (HS1) was reinterpreted as the generalized condition in Agoristenidae, except for some cases (e.g. Globibunus Roewer, 1912, Muscopilio Villarreal & García, 2021, Barlovento González-Sponga, 1987, Leptostygnus Mello-Leitão, 1940, Vima Hirst, 1912, and some species of Avima). We obtained a monophyletic Paravima in all cases, defined by (a) ocularium placed close to the anterior margin of the carapace [ctr 11(1)], and (b) absence of longitudinal dorsal keel on the stylus [ctr 42(0)], both homoplastic synapomorphies (Fig.

Sensitivity plots (‘Navajo rugs’) indicate the recovery of the nodes in the analyses under implied weights with K values of 1, 2, 4 and 8. Clear circles represent homoplastic synapomorphies and filled circles represent non-homoplastic synapomorphies.
However, the internal relationships within Paravima have not been fully resolved (Figs

Paravima magistri appears as sister group to the rest of the species, supported by (a) the proportion of interocular distance vs width of carapace; (b) the unmodified shape of the spines of area III and (c) MS-A quantity (only two pairs vs three pairs). The remaining taxa are clustered in a polytomy formed by two groups of species and two isolated species. The more specious group gathers most of the species with area III armed, from sectors further east of Cordillera de la Costa in Venezuela (except P. totoro). P. plana and P. quirozi, the unarmed species, are clustered for sharing, in addition to the absence of ornamentation on mesotergal area III [17(0)], the elongation of the base of the LP [47(0)] (Fig.
Due to the unarmed mesotergal area III, these species were historically related to Avima. However, our study confirms the degree of homoplasy of this character. Other morphological similarities, which are now known to be shared with Paravima, were first detected by Villarreal-M & Rodríguez-Manzanilla (2003), but not tested in a phylogenetic analysis. Our results strongly support the monophyly of Paravima, but the internal relationships within the genus are not stable enough to propose any infrageneric or supraspecific taxonomic organization at this time.
The interpretation of some states of character in some species was difficult, due to the unavailability of genitalia specimens for study (e.g. P. morritomacairensis, P. locumida) which necessitated reliance on schematic drawings from the literature, e.g. MS D and MS E, being hard to discern between if these drawings are incomplete or if certain genital structures truly do not exist. Additionally, limited information on morphological variability (Fig.
A parallel analysis under equal weights offers interesting results (Fig.
Little is known about the natural history of the Paravima species, with limited information available on the biomes and microhabitats they occupy. From a biogeographical approach, most species are restricted to the biogeographic Venezuelan province in the Cordillera de la Costa in Venezuela. However, two new species have been recorded in the Magdalena province in Colombia (Fig.
Paravima species occupy a wide range of altitudes and diverse biomes. Many of the species have been recorded from Montane Cloud Forests at altitudes between ~1200–1945 m a.s.l. (P. totoro, P. plana, P. goodnightorum) (Fig.

Two major problems have affected the taxonomy of Paravima: (1) the use of the Roewerian taxonomic system and, (2) the incomplete original descriptions/drawings. The armature of the scutal area III was used for the creation of artificial groups, i.e. all the agoristenid without any armature on area III were classified as Avima, ignoring other characters, as the genital morphology (see
