description: 3.1.1.2. Trachyuropoda bali sp. nov.
Material examined: Holotype: Female. Colombia, near Rio Claro, from leaf litter, 15 May 1984, leg. J. Balogh (HNHM). Paratypes: 2 females, locality and date same as in holotype (1 paratype in ISB, 1 in HNHM).
Description: Female. Length of idiosoma 1290–1320 µm, width 1010–1020 µm (n = 3). Shape oval, posterior margin rounded.
Dorsal idiosoma (Figure 6a): Marginal and dorsal shields completely separated. Dorsal shield hypertrichous, dorsal setae (ca. 70–79 µm) smooth and spine-like (Figure 6b). Dorsal shield bearing 1 pair of L-shaped grooves bordered with long (ca. 57–64 µm), smooth, and spine-like setae (Figure 6b). Dorsal shield covered by alveolar pits. Margin of dorsal shield strongly sclerotized. Marginal shield without ornamentation, marginal setae spine-like (ca. 51–57 µm).
Ventral idiosoma (Figure 6c): Surface of sternal shield smooth, except the area anterior to genital shield where reticulate sculptural pattern can be found. Several T-shaped sternal setae can be observed. Ventral shield covered by alveolar pits and bearing numerous smooth and spine-like setae (ca. 31–34 µm). Setae around anal platelets similar in shape to ventral setae, except the short (ca. 15 µm) postanal seta (Figure 6d). Stigmata situated between coxae II and III, peritremes M-shaped, asymmetric, the posterior loop longer than the anterior (Figure 6c). Genital shield linguliform, its surface smooth in central area, but covered by oval pits near its lateral margins. Apical process absent. Base of tritosternum narrow, tritosternal laciniae divided into 4 apically serrate branches (Figure 6e). Pedofossae deep and their surface smooth. Separated furrows for tarsi IV absent.
Gnathosoma (Figure 6f): Corniculi horn-like, internal malae divided into several marginally pilose branches. Hypostomal setae are as follows: h1 (ca. 80 µm) smooth and situated near the anterior margin of gnathosoma; h2 (ca. 60 µm), h3 (ca. 69 µm), and h4 (ca. 77 µm) long and marginally serrate. Epistome subtriangular and marginally pilose (Figure 6g). Chelicerae (Figure 6h) without internal sclerotized node, movable digit shorter than fixed digit. Movable digit with 1 tooth, fixed digit bearing 2 teeth. Trochanter of palps bearing a short and smooth and a long and marginally serrate seta; other setae on palps smooth.
Male, nymphs, and larvae are unknown.
Etymology: We dedicate the new species to Dr Durmuş Ali Bal, the excellent Turkish Uropodina researcher.
Notes: The new species belongs to the Trachyuropoda graeca- group on the basis of the presence of the strongly sclerotized rectangular or L- and c-shaped dorsal grooves (Hirschmann, 1976). This group contains 7 species, but only 4 already known species (T. mesofovea Hirschmann, 1976; T. mesofoveasimilis Hirschmann, 1976; T. represa Hirschmann, 1976; and T. rufipes Hirschmann, 1976) have L- or c-shaped dorsal grooves on the posterior area of the dorsum. The distinguishing characteristics of the species having L- or c-shaped dorsal grooves are shown in Table 2.
