Diagnosis

Males of Tabiboka milleri gen. et sp. nov. may be distinguished by the morphology of the palpal tibia with the RTA having an elongate curved spur arising retrobasally and extending distally to the apex of the tibia ( Figs 5B–C , 6A–C ) (vs T. milloti gen. et sp. nov. and T. polotowae gen. et sp. nov. have a short and stout RTA, Figs 9B–C , 11B–C ), a short, broad embolus (E) and a small, slender paraconductor (Pc) largely hidden behind the embolus ( Figs 5A–C , 6D–F ) (vs in T. milloti and T. polotowae , the E is slender and the Pc is situated between the E and the C, Figs 8F , 9B, 11B, 12E). Females of T. milleri have the epigyne with a broad, swollen, oval median lobe (ML) that extends posteriorly beyond the epigastric furrow, narrow anteriorly (anterior width less than half the total width, Figs 4B , 5D , 7A ) (vs in T. milloti , the ML is broad anteriorly, Fig. 9D ; and in T. polotowae , the ML is medially narrowed, Figs 11D , 12G ).

Etymology

The species name is a patronym in honor of Jeremy Miller, who collected widely in Madagascar and led a team that carried out a pioneering study of entelegyne spider phylogeny ( Miller et al. 2010).

Variation

Males (n = 5)

Male genitalia display slight geographic variation. Males from Ranomafana have very slender retrobasal tibial processes, with length greater than 20 times width, whereas in males from Ankazomivay and Tsinjoarivo these are thick, with length less than 15 times width. The distal RTA may be deeply cleft in males from Ranomafana or only slightly cleft as in males from Ankazomivady. Most individuals have a crack across the subbasal part of the leg tibia just distad of the basalmost ventral spines, but this varies. Within the Ranomafana population some have the tibial leg crack clearly marked whereas in others the crack cannot be distinguished. Total length = 9.60–12.00, carapace length/width = 1.28–1.41, carapace height/width = 0.44–0.59, PER/carapace width = 0.24–0.26, PER/OAL = 2.33–2.65, PER/AER = 1.38– 1.46, OAL/OQL = 1.24–1.42, OQP/OQA = 1.46–1.57. Clypeus height/AME = 1.20–2.86, cheliceral length/clypeus height = 8.00–13.33, sternum length/width = 1.11–1.19, palpal coxa length/width = 2.14–2.50, femur I length/carapace width = 1.04–1.22, metatarsus I length/carapace width = 1.02–1.11, femur IV length/carapace width = 1.09–1.30, cymbium length/carapace width = 0.36–0.42, cymbium length/palpal patella length = 1.45–2.43, cymbium length/palpal tibia length = 1.23–1.90, cymbium length/palpal femur length = 0.76–0.92, palpal tibia length/palpal patella length 1.00–1.57.

Females (n = 5)

Total length = 11.50–14.00, carapace length/width = 1.26–1.31, carapace height/width = 0.45–0.65, PER/carapace width = 0.25–0.33, PER/OAL = 2.44–2.95, PER/AER = 1.35–1.70, OAL/OQL = 1.13– 1.38, OQP/OQA= 1.33–1.71, clypeus height/AME = 1.60–2.40, cheliceral length/clypeus height = 7.67– 12.50, sternum length/width = 1.14–1.30, palpal coxa length/width = 1.94–2.57, femur I length/carapace width = 0.92–1.10, metatarsus I length/carapace width = 0.62–0.71, femur IV length/ carapace width = 0.92–1.10, palpal tarsus length/carapace width = 0.32–0.37, palpal tarsus length/palpal tibia length = 1.15–1.31, palpal tarsus length/palpal femur length = 0.74–0.86, palpal tibia length/palpal patella length = 1.08–1.37. The oval epigynal median lobe may be evenly curved in lateral outline ( Fig. 5D ) or be attenuated posteriorly ( Fig. 4B ). Median lobe length 0.93–1.38 times width, with median lobe extending posteriad of epigastric furrow by 0.11–0.29 of lobe length. Spermathecae may be evenly rounded or have as many as two shallow dorsal constrictions. Spermathecae separated by 0.27–0.35 the total width of the spermathecae.

Note on synonyms

Specimens of this species have been used as exemplars in previous studies including morphological documentation and in published molecular phylogenies. The morphology of the species was documented for the Spiders Assembling the Tree of Life (AToL) study (2001–2009) as the exemplar “ Zorocratidae gen. Talatakely sp. Talatakely”, Images [476092–509952] SpiderAToL, March 3, 2008, https://www.morphbank.net/?id=218853 ( Morphbank 2023): CASENT_9016094. Specimens were used as the exemplars “ Zorodictyna sp. 2 ” by Polotow et al. (2015) (CASENT_9035866) and as “ Zorodictyna sp. CG300” by Wheeler et al. (2017) (CASENT_9024004).

Natural history

This species is commonly found running on leaf litter in closed-canopy montane rainforest. Individuals were also collected in pitfall traps or under objects.

Distribution

Tabiboka milleri gen. et sp. nov. are known only from rainforests in Antananarivo and Fianarantsoa Provinces in southeastern Madagascar ( Fig. 26 ).
