Figs 9 , 18

Paravima morritomacairensis González-Sponga, 1987: 482, figs 618-623; Kury, 2003: 31.

Diagnosis.

Paired tubercles on the mesotergal area III spiniform, gradually sharpening (shared with P. magistri sp. nov., from which it can be distinguished by the absence of a dark spot in the mesotergal areas). The remaining Paravima species lack ornamentation or have conical, mammilliform or domed tubercles).

Description.

See González-Sponga (1987). Here we offer a complementary description (based on MIZA 0105923 and González-Sponga 1987: figs 622, 623): Margins of DS, chelicerae, and pedipalps variegated (Fig. 9A ). Anterior and lateral margins of DS smooth, posterior margin with some granules (Fig. 9A, B, D ). Area III with a pair of paramedian mammilliform tubercles (higher than ocularium) darker than the rest of the mesotergum (Fig. 9A-C ). Anterior margin of coxa I with a high proximal conical tubercle (Fig. 9E ). Fe IV is three and a half times DS length. Malleus of penis with one pair of branched MS-B; MS-D absent (see Remark); one pair of MS-E2 large and branched. Stylus elongated, surpassing the lamina parva.

Distribution.

Known from Guárico state, in the Venezuelan biogeographic province ( Morrone et al. 2022) (Fig. 18 ).

Material examined.

Type material: Holotype ♂, VENEZUELA, Guárico, Monagas, El Morrito, road Altagracia de Orituco-San Francisco de Maicara [Macaira] | [9.89933° -66.30614°] | 850 m | 10.iv.1982, Reyes Torrealba leg. (MCNC 967, not examined) .- Paratypes 1 ♀, same data as holotype, (MCNC 968, not examined) ; 1 ♂ 10 ♀, same data as holotype, (MAGS, not examined) . - Other material: VENEZUELA: 2 ♂ 8 ♀, Guárico, Monagas, El Morrito de San Francisco de Macaira , 10.iv.1982, Reyes Torrealba leg. (MAGS 504 (MIZA 0105923)) ; 1 ♂, same data as previous (dissected), (MIZA 0105924) .

Remarks.

One of the males of MIZA 0105923 was dissected but the genital was not together with the male; another male was without genital operculum nor penis. MCNC material seems to be lost (not found in MAGS collection). We suspect that MAGS 504 corresponds to the material cited as MAGS, without number. The figures of the penis by González-Sponga (1987: figs 622, 623) does not show MS-D, but this is probably an omission ( Paravima typically has two pairs of MS-D). Specimens of this species are extremely similar to P. locumida and a detailed review of the genitalia and variability of both taxa would be useful to determine their identity.
