Calvanese, Victor C., Brescovit, Antonio D., Bonato, Lucio (2019): Revision of the Neotropical species of Aphilodontinae (Geophilomorpha, Geophilidae), with eight new species and a first phylogenetic analysis of the subfamily. Zootaxa 4698 (1): 1-72, DOI: 10.11646/zootaxa.4698.1.1

Description of holotype. Female (IBSP 3664). Entire body: length 21, maximum width 0.65. Cephalic plate: anterior and posterior margin rounded, length 0.50 and width 0.45 (length / width ratio 1.11), with little scattered SE. Antenna: length 1.13, ca. 2.2 times as long as cephalic plate; AA II – XIII length / width ratio 0.6 – 0.9; LAA ca. 3 times as long as AA XIII. Clypeus: 3 + 3 LS, 1 + 1 PS, 5 + 5 SCS. Mandible: PL with 25 denticles. First maxillae: TFM length 0.039 and width 0.03; DA with 2 apical and 2 subapical SL; MPC with 3 apical and 1 subapical SL. Second maxillae: left TSM length 0.07 (1.85 times as long as TFM) and maximum width (basal margin) 0.037; left T 3 length 0.01 (cs. 0.5 times as long as T 2) and width 0.01 (0.32 times as wide as T 2); both TSM with 1 apical SE. Forcipular segment: FTE length 0.18 (0.36 times as long as cephalic plate) and width 0.56; FPT length 0.04 and width 0.38; FCX length 0.45 and width 0.47 (length / width ratio 0.95); FRL length 0.41, reaching anterior margin of cephalic plate, and maximum width (middle part of TFF) 0.23; FRL with two denticles in TFF and one in TI; FD 1 with 1 apical SE; FD 2 with 1 apical and 1 subapical SE; FD 3 with 1 apical and 2 subapical SE; TA 0.88 times as long as TFF and with small basal DTA. Walking legs: 59 pairs; left FL length 0.52, 0.75 times as long as second leg; left leg 29 length 0.9. Tergum from the first to penultimate leg-bearing segment: TE 29 length 0.36 and width 0.66 (length / width ratio 0.54), with one anterior row of 8 SE, one posterior row of 8 SE and little SE sparse between the rows; PT 0.6 times as long as TE and with two parallel rows of 5 – 8 SE. Sternum from the first to penultimate leg-bearing segment: STF oval, slightly narrower in anterior part; ST 29 length 0.40 and width 0.27 (length / width ratio 1.48). Ultimate leg-bearing segment: MTL trapezoidal, length 0.13 and maximum width 0.30 (length / width ratio 0.43); UPS exposed and not suppressed in middle part, length 0.03 and width 0.38. Ultimate legs: thin, length 1.57, 1.4 times as long as penultimate leg; each CXP with 7 or 8 COP, closely grouped together with MTL. Postpedal segments: GF with 1 + 1 distal SE. Known variation. Male: 57 leg-bearing segments; each CXP with 4 – 6 large COP; ultimate legs with prefemur, femur and tibia wider than long and tarsal article globose, all articles quite hairy; GM biarticulated; GM 1 with 5 or 6 SE in one row; GM 2 with 7 – 9 scattered SE.

Diagnosis. A species of Mairata n. gen. with: around 57 – 59 leg-bearing segments; known body length in adults 18 – 23 mm; distal denticle of forcipular trochanteroprefemur with one apical seta (Fig. 33 H); coxopleuron with 2 – 8 large coxal pores in adults, grouped near the metasternite, in both males and females (Figs 12 A, E, 33 K – L, 34 E – G, 45 D); females with ultimate legs not thickened when compared to penultimate legs (Figs 33 K, 34 A, D – E). Recorded specimens: 11, including 6 ♀ and 5 ♂, from two localities.

Distribution. Brazil — São Paulo: Cotia; São Roque.

Etymology. The epithet is a noun in apposition, referring to the Butantan Institute, recognized worldwide for its promotion of biological research.
