Trachyuropoda bali, Kontschán & Starý, 2013

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 View Figure 6 ): Marginal and dorsal shields completely separated. Dorsal shield hypertrichous, dorsal setae (ca. 70–79 µm) smooth and spine-like ( Figure 6b View Figure 6 ). Dorsal shield bearing 1 pair of L-shaped grooves bordered with long (ca. 57–64 µm), smooth, and spine-like setae ( Figure 6b View Figure 6 ). 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 View Figure 6 ): 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 View Figure 6 ). Stigmata situated between coxae II and III, peritremes M-shaped, asymmetric, the posterior loop longer than the anterior ( Figure 6c View Figure 6 ). 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 View Figure 6 ). Pedofossae deep and their surface smooth. Separated furrows for tarsi IV absent.

Gnathosoma ( Figure 6f View Figure 6 ): 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 View Figure 6 ). Chelicerae ( Figure 6h View Figure 6 ) 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 View Table 2 .
