Specimens pale white with purple pigments on Ant IV, internal side of the Ant II–III, and weakly present on anterior and posterior head, and basal part of tibiotarsus I.

Scales present on Ant I to proximal one quarter of Ant III, proximal Ant IV, dorsal and ventral head, dorsal thorax and abdomen, legs (except empodia), anterior and posterior collophore, ventral and dorsal manubrium and dens ventrally.
Head. Antennae smaller than trunk length (Fig. 32); ratio antennae: trunk = 1: 1.35–1.84 (n=4), holotype 1: 1.40; antennal segments ratio as I: II: III: IV = 1: 1.43–1.59: 2.2–2.44: 2.38–3.34, holotype 1: 1.43: 2.2: 2.38. Ant IV completely annulated with apical bulb apically unilobed or bilobed. Ant III annulated on distal three fourths, apical organ with 2 club-shaped sens, 3 spiny guard sens, s-blunt sens of different sizes and ciliated chaetae (Fig. 33A). Ant I dorsally with 3 median mac and 3 smooth mic at the base, apparently without spines (Fig. 33B). Eyes A and B larger, G and H smaller, others subequal, and with 5 ‘IO’ chaetae; head dorsal macrochaetotaxy with 10 An, 4 A, 4 M, 7 S and 1 Pp mac. (Fig. 33D). Clypeal formula with 4 (l1–2), 3 (ft), 3 (pf0–1) ciliated chaetae, l1–2 larger than others, l1 apically acuminate, others subequal (Fig. 33C). Prelabral chaetae ciliated and not bifurcated. Labral p0 chaeta without median filament, p0–1 larger than others. Labral papillae with two inner conical projections, outer papillae absent (Fig. 33C). Maxillary palp with smooth t.a and b.c. finely ciliated, thicker and 1.09 longer than the t.a. (Figs. 34B). Labial papilla E with l.p. apically pointed and surpassing the base of a.a. (Fig. 34A). Basolateral and basomedian labial fields with chaetae M1–2, R (smaller than others), E, L1–2 ciliated (Fig. 34C). Ventral head with about 22 ciliated chaetae, postlabial formula with 4 (G1–4), 3 (H2–4), 4 (J1–4) chaetae, 5 thin posterior chaetae, and 3 larger chaetae, 1 b.c. surrounding the cephalic groove (Fig. 34C).
Thorax chaetotaxy (Fig. 35 A–B). Th II projected anteriorly, a, m and p series with 13–14, 8 and 11 mac, respectively. Th III a, m and p series with 2, 0 and 8 mac, respectively. Ratio Th II: III = 1.90–1.40: 1 (n=4), holotype 1.40: 1.
Abdomen chaetotaxy (Figs 35 C–D, 36A–C). Abd I a, m and p series with 1, 4 and 0 mac, respectively, m4 absent. Abd II a, m and p series with 1, 4 and 0 mac, respectively.

Abd V a, m and pa / p series with 1, 4 and 1/5 mac, respectively. Ratio Abd III: IV = 1: 3.53–4.48 (n= 4), holotype 1: 4.14.

Subcoxa I with 5 chaetae on a row and 2 psp; subcoxa II with an anterior row of 9 chaetae, posterior row of 4 chaetae, 2 extra chaetae near p row and 6 psp; subcoxa III with one row of 9 chaetae and 2 posterior psp (Figs 37 A–C). Trochanteral organ with about 23 spine-like chaetae (Fig. 37D). Tibiotarsus not subdivided, outer side with 3 proximal larger ciliated chaetae apically acuminate (e), inner side with 9 mac weakly ciliated (ai and pi), and anterior side with 2 mac (ae) on proximal half (Fig. 37E). Unguis with 4 inner teeth, b.t. subequal to m.t. in length, a.t. smaller. Unguiculus with all lamellae smooth and acuminate, except pe serrated and with a small proximal tooth; ratio unguis: unguiculus = 1: 0.57. Tibiotarsal smooth chaeta 1.08 larger than unguiculus and tenent hair 0.90 smaller than unguis outer edge (Fig. 37F).
Collophore. Anterior side with 14 chaetae, 7 proximal spine-like chaetae, 1 ciliated chaeta, 4 ciliated chaetae apically acuminate and 2 mac distally; posterior side with 5 chaetae, 4 thin ciliated chaetae widely distributed and 1 smooth chaeta distally; lateral flap with about 19 chaetae, 5 smooth and 14 ciliated (Fig. 38A).
Furcula. Manubrium ventral formula with 1, 0, 0, 0/0 (subapical), 14 (apical) ciliated chaetae plus approximately 15 elongated apical scales per side (Fig. 38B); manubrial plate with 1 blunt mac ciliated abruptly acuminate at the apex, 5 ciliated chaetae of different sizes and 2 psp. Dens dorsally with one proximal row of 3–4 blunt mac weakly ciliated and apically bullet-like, holotype with 3 (Fig. 38C).
Etymology. Refers to the type locality of the new species, Botswana.
Remarks. Lepidocyrtinus botswanensis sp. nov. resembles L. annulicornis in antennae subequal to trunk length, Th II with 6 median mac in m1–2 complex and 11 posterior mac, Th III to Abd II with 9, 5 and 4 central mac, respectively, and unguiculus pe lamellae serrated. However, L. botswanensis differs from this species by color pattern (see remarks of L. africanus), unguiculus pe lamella with a small proximal tooth (absent in L. annulicornis) and manubrial plate with 1 mac abruptly acuminate at apex (2–3 in L. annulicornis).
