(Figs. 6‒10)
Description. Body length 4.2 to 5.4 mm (four females, holotype included). Total cercal length unknown, up to 3.0 mm in paratype 4.2 mm long. Epicuticle with thick microspines (Figs. 6‒8); body with short and smooth clothing setae.
Antennae with 21 antennomeres in a regenerated antenna. Sensillum of third antennomere subcylindrical, sharply pointed, located in ventral position between macrosetae d and e. Central antennomeres 1.2 times longer than wide. Apical antennomere 2 times longer than wide, its cupuliform organ containing 10‒12 sensilla with 2 or 4 collarettes. Abundant gouge sensilla (Fig. 10) with 10 to 14 sensilla in one single distal whorl on medial and distal antennomeres, with less numerous sensilla on the fourth antennomere. Frontal process well developed (Fig. 8), with several smooth, slightly tuberculate setae. Three macrosetae along line of antenna insertion with relative lengths in 5-mm-long female paratype as a = 0.75, p = 1, i = 0.75. Suboval labial palp with subcylindrical, sharply pointed latero-external sensillum similar to sensillum of maxillary palp and third antennomere, plus two guard setae, 10 setae on anterior border and 50 neuroglandular setae, in the largest paratype.
Thoracic nota slightly elongated. Distribution of macrosetae (Fig. 6): pronotum with 1+1 ma, 1+1 la, 1+1 lp; mesonotum and metanotum without macrosetae. All macrosetae short, thick, with numerous long barbs along the distal half. Marginal setae long and thick, with barbs along the distal half. Legs elongated, metathoracic legs reaching abdominal segment VIII. Femur III without dorsal macrosetae. Tibiae without ventral macrosetae. Calcars with numerous barbs from base to tip. Dorsal and lateral tarsal setae smooth. Subequal elbow-like claws (Fig. 9) with smooth, well developed lateral crests and with a short extension at the basal end of the posterior claw. Body of claw transversally striated. Telotarsal process smooth and setiform.
Distribution of abdominal macrosetae on tergites: 3+3 post macrosetae on VIII, 5+5 post macrosetae on IX. Urosternite with 6+6 thick macrosetae with long barbs, urosternites II to VII with 4+4 macrosetae, urosternite VIII with 1+1 macrosetae. Apical, subapical and medial sternal setae completely covered with long barbs.
Cerci with base followed by up to 28 short primary articles, each with 4 to 8 whorls of barbed macrosetae on proximal articles to smooth macrosetae on distal articles, mixed with whorls of smooth setae.
Female subcylindrical appendages of urosternite I with a field of 12 a1 -glandular setae, in paratype 5.4 mm long.
Type material. Holotype female and three female paratypes from “Sótano Los Hernández” at - 300 m deep, 20°55’ N, 99°34’ W in Sierra Gorda’s massif limestone, San Joaquín, Querétaro, México, 19 IV 2014, A. García leg., mounted in Hoyer’s solution, deposited in UNAM. One female paratype from the nearby cave “Cueva La Herradura” at - 130 m deep, 20°53’ N 99° 34’W,, San Joaquín, Qerétano, México, 24 V 2009, A. García leg. mounted in Hoyer’s solution, deposited in UNAM.
Etymology. This species is dedicated to the well-known Spanish entomologist, biospeleologist and politician Cándido Bolivar y Pieltain (born 1867, Madrid—died 1975, México D.F.) who is considered the pioneer of biospeleology in Mexico, his adoptive country, as he was from Spain.
Remarks. Features of the telotarsus and the reduction of thoracic macrosetae (3+3 ma, la, lp, 2+2 ma, la and 1+1 ma) place Tachycampa bolivarpieltaini n. sp. alongside two other new Tachycampa species proposed from Mexican caves (see below), which together can be considered part of the “tachycampoide” group and provisionally put in Tachycampa. Tachycampa bolivarpieltaini n. sp. lacks macrosetae on the mesonotum, metanotum and urotergites I‒VII. These features and the thick microspines on the epicuticle distinguish T. bolivarpieltaini n. sp. from other Tachycampa species.
