Kiskalla is an adjective in Quechua language that means “spiny” and refers to the large number of spines on all legs, particularly in males. The genus gender is feminine.

Kiskalla ignacioisp. nov.

The new genus differs from all remaining Theraphosinae genera by the following combination of characters: the presence of lateral abdominal stripes (Figs 2F, 4C, 9), a small dorsal arrowhead-shaped patch of type III urticating setae (Figs 8C, 9D, 10B, 12G), presence of short, stout setae on the dorsal metatarsi encircling the filiform trichobothria (Fig. 4H), an apical crown of long spines on ventral metatarsi of all legs in both sexes (Figs 4G, 10G) and tarsi IV with slightly-developed scopula restricted to the margins due to the presence of long ventral setae (Fig. 4G). In addition, males and females share a general similarity in the shape of the palpal bulb and spermathecae with those of Hapalotremus. However, males are readily distinguished by the presence of a very large and serrated SA keel on the palpal bulb, combined with a well-developed PI keel on embolus and a barely perceptible PS keel (Figs 3A–D, 7), a projection on the retrolateral face of the cymbium (Fig. 6A), tibiae of legs I about 1:3 longer (Fig. 5A), and a tibial apophysis not arising from a large common base (Fig. 5). Females are distinguished from Hapalotremus by having a single dome-shaped receptacle lacking both apical and basal lateral projections (Figs 8E, 10H, 12F, 13H).

Kiskalla shares with other Peruvian Theraphosidae inhabiting high montane regions the presence of only type III urticating setae, as in Anqasha Sherwood and Gabriel, 2022; Antikuna; Bistriopelma; Chinchaysuyu Ferretti et al., 2023; and Hapalotremus. Females of Kiskalla differ from all the above genera (except Hapalotremus) by the presence of a single spermathecal receptacle. Kiskalla further differs from Anqasha by the general morphology of the male palpal bulb: the embolus of Kiskalla lacks the R keel, which is present and well-developed in Anqasha (Sherwood and Gabriel 2022a; Kaderka 2023). Males of Kiskalla also differ from those of Antikuna by possessing a well-developed, serrated SA keel and only a slightly-developed PS keel, whereas Antikuna species show a small SA keel and a well-developed PS keel (Kaderka et al. 2021). Kiskalla is easily distinguished from Bistriopelma by having a single dorsal patch of urticating setae on the abdomen instead of the two patches characteristic of Bistriopelma and by the morphology of male palpal bulb (Kaderka 2015). In addition, Kiskalla differs from Chinchaysuyu in the morphology of the male palpal bulb, which in Kiskalla bears PS and PI keels, whereas Chinchaysuyu shows a multiple rolateral accessory keels extending across the tegulum, along with the presence of an R keel (Ferretti et al. 2023; Kaderka 2024). Males of Kiskalla are further distinguished from those of Hapalotremus by the presence of a cymbial retrolateral projection, a well-developed serrated SA keel, and a weakly-developed PS keel on the prolateral face of embolus but highly distinct in ventral view; females differ by lacking apical and lateral projections on the spermathecae, which are variable developed in Hapalotremus (Ferretti et al. 2025). Finally, Kiskalla differs from some representatives of Thrixopelma that bear only type III urticating setae, by the non-spatulate embolus of the male palpal bulb, the PI keel lacking crests, and the absence of an R keel on the embolus (Sherwood et al. 2021).

Kiskalla comprises small-sized brown to grey tarantulas, with total body length ranging from 11.8 to 19.1 mm (excluding chelicerae and spinnerets). Carapace oval, uniformly colored; caput highly elevated in Kiskalla zukuapasankasp. nov. Ocular tubercle oval, slightly to high elevated, wider than long, bearing eight eyes, anterior eye row slightly procurved to procurved, posterior row recurved in dorsal view. Clypeus narrow. Fovea transverse, deep and wide, procurved. Chelicerae lacking rastellum and stridulatory bristles; promargin with 10–12 teeth. Labium wider than long, with 4–24 cuspules restricted to the anterior third. Maxillae with 66–170 cuspules on the basal half of the ventral side. Ventral surface of maxillae with apical half to nearly the entire surface covered by short spiniform setae. Sternum rounded with long soft setae on margins, three pairs of oval sigillae. Abdomen with lateral black stripes along the margins (more conspicuous in Kiskalla ignacioisp. nov.) and with a single dorsal arrowhead-shaped patch of type III urticating setae. Legs very spinose; tarsi IV lacking scopulae or with scopulae poorly developed and restricted to the margins by long setae. Leg formula: I>IV>II>III in males, IV>I>II>III in females. Femur III incrassate in males. Palpal bulb of males with globose tegulum and a tegular projection, embolus wide, retrolaterally curved with four keels: A, PI, PS and SA serrated. Spermathecae of females consists in a single subquadrate dome-shaped receptacle with large granules.

This species is named in honor and in loving memory of Ignacio Enrique Quispe-Escobedo, father of Oscar M. Quispe-Colca, with whom Oscar spoke a lot about the discovery of this species.

Kiskalla ignacioisp. nov. differs from K. yeisonisp. nov. and K. zukuapasankasp. nov. by its distinctive coloration: carapace, legs and palps blackish-brown with whitish pubescence; abdomen dorsally black with short lateral bands contrasting with a whitish ventral surface (Figs 2D, 2F, 4C, 9B). Females of K. ignacioisp. nov. also differ from congeners by the shape of the spermathecae, which consists in a single sub-quadrate seminal receptacle (Figs 8E, 10H).

males. The paratype male from a locality near that to the holotype presents eight labial cuspules and a more rounded sternum (Fig. 4D, E). The carapace shares the wittish setae on margins but it is covered by iridescent purple setae (Fig. 4A, F); lateral abdominal stripes and pale margins are so more conspicuous (Fig. 4B, C) and the urticating patch is slightly displaced towards the central portion of the dorsal abdomen (Fig. 4B). Both the holotype and paratype males share ventral maxillae with the apical half covered by short spiniform setae (Fig. 4E) as well as short, stout setae on the dorsal metatarsi encircling the trichobothria (Fig. 4H). The tibial apophyses have some differences, the male paratype has a more curved RB along with a stout spine on the apical portion (Fig. 5). In relation to the palp configuration, the male paratype has a more developed cymbial projection on the retrolateral face (Fig. 6A) and the palpal bulb has a PS slightly more distinct than in the holotype male and a well-developed tegular projection along with a more serrated SA keel (Fig. 7A–D).

One of the paratype female (Fig. 10) from a locality near the type site presents five to seven labial cuspules (Fig. 10E), a more strongly procurved fovea (Fig. 10A) and more conspicuous lateral abdominal stripes (Fig. 10B, D). Possibly due to preservation conditions, the females from the Chacaconiza community (MUBI 313, 314) have the entire abdomen covered by short plumose setae, given a “fluffy” appearance (Figs 10B, 10D, 11), a feature not evident in one of the other female paratype (Fig. 8C). Aside from these specific differences, all examined females share the same general morphology; ventral maxillae covered with short spiniform setae restricted to the apical half (Fig. 10E), tarsi IV with only slightly developed scopulae (Fig. 10G) and the spermathecae with a single subquadrate seminal receptacle (Fig. 10H).

Kiskalla ignacioisp. nov. is known from Corani locality at Puno department, Peru (Fig. 16), found at elevations of 4360–4570 m a.s.l. The habitat is characterized by a cold and mountainous environment, with a mean annual temperature of –6°C to 12°C. The vegetation comprises mainly grasslands near to wetlands known as “bofedales” (Fig. 2E). The male holotype was found under a stone without any apparent retreat, the female paratype was found under a stone inside a burrow without discernible webbing and ranged in length between 18–20 cm. Male and female paratypes were found in the field between 2014 and 2024 in areas near the community of Chacaconiza, Corani District, Carabaya Province, Puno Department, Peru. The species inhabited puna grassland formations including tussock grass (pajonal), puna turf, and cryoturbated zones, always associated with rocky outcrops or scattered medium to large-sized stones. Individuals were found beneath stones, usually in small burrows excavated under them, at depths ranging from 20 to 80 mm. During field observations, wasps of the family Pompilidae (known as tarantula hunters) were also recorded in the vicinity of the species’ habitat. It is worth noting that in the area of occurrence, there are plans for the development of two medium-scale open-pit mining projects, which may pose a potential threat to populations of this species.

Holotype: PERU • 1♀; Puno, San Antonio de Putina, Putina; 4000 m a.s.l.; 07.V.2022; O. M. Quispe-Colca col.; MUSA-AR 319.

PERU • 1♀; same data as for holotype; MUSA-AR 321.

This species is named in honor of Yeison A. Calizaya Melo, a close friend of Oscar M. Quispe-Colca, who regards him as a younger brother.

Females of Kiskalla yeisonisp. nov. differ from congeners by the distribution of short spiniform setae covering most of the surface of maxillae (Fig. 12E), whereas in K. ignacioisp. nov. and K. zukuapasankasp. nov., these setae are restricted to the apical half. Kiskalla yeisonisp. nov. also differs from K. ignacioisp. nov. by its coloration: carapace, legs, and palps dark-brown; abdomen pale brown, lacking lateral bands (Fig. 12G); and spermathecae consisting of a single dome-shaped receptacle with small granules (Fig. 12F), instead of a sub-quadrate receptacle with large granules. Females of K. yeisonisp. nov. resemble those of K. zukuapasankasp. nov. in the general aspect of the spermathecae, but can be easily distinguished by the lower number of labial and maxillary cuspules (Fig. 12E), a shorter fovea (Fig. 12A), and a slightly elevated caput (Fig. 12A).

Kiskalla yeisonisp. nov. is known only from Putina locality at Puno department, Peru (Fig. 16), found at elevation of 4000 m a.s.l. The habitat is characterized by a cold and mountainous environment, with a mean annual temperature of –5°C to 17°C. The vegetation comprises mainly scrubs and grasslands near to relict “queñua” forest (Polylepis incarum Bitter and P. triacontandra Bitter) (Fig. 12H), however, there are also nearby crop areas as well as grazing of cattle, sheep and camelids. The entrance to the burrow of the female holotype was found under a rock without any discernible webbing, at a depth between 15 and 20 cm below the ground.

The specific name zukuapasanka is derived from the Quechua words zuku, meaning “grey-haired,” and apasanka, a local name for tarantulas. The epithet refers both to the general appearance of the species, characterized by its greyish setae, and to the common name used by local communities for these spiders.

Females of Kiskalla zukuapasankasp. nov. resemble those of K. yeisonisp. nov. in the general aspect of the spermathecae (Fig. 13H) and those of K. ignacioisp. nov. in having the ventral maxillae with short spiniform setae restricted to the apical half (Fig. 13F). However, K. zukuapasankasp. nov. can be easily distinguished from its congeners by the higher number of labial cuspules (8–24 in K. zukuapasankasp. nov. versus 4–7 in K. ignacioisp. nov. and K. yeisonisp. nov.), a broader fovea (Fig. 13A), a highly elevated caput (Fig. 13A, C) and booklung openings bordered by short, stout setae (Fig. 13D).

Kiskalla zukuapasankasp. nov. is known only from Abra Sallaco and Cuyo Cuyo localities at Puno department, Peru (Fig. 16), found at elevations of 4000–4220 m a.s.l. The habitat is damp and mountainous featuring steep valleys with rocky talus slopes (Fig. 15A) with seasonal temperatures ranging from a low of –4°C to a high of 17°C. Vegetation is sparse and consists of patches of mosses and low grasses. Females and subadults were found in ground retreats under large angular rocks laying on the ground surface. These retreats lacked any discernible webbing at the entrance and appeared to be self-excavated. The retreats under the rock ranged in length from 20 to 40 cm with the end angling deeper into the ground (Fig. 15B).
