No full textDjeboa obovata (Cook, 1966) (Figs. 31 A–F) Mideopsis (Djeboa) obovata Cook 1966: 240. Material examined: Type series: FMC, Liberia; holotype female, Congo Town area, water filled ditch, 30.vii. 1958 Cook (Coll. 105); paratype male, same data as holotype. General features: Idiosoma tapering posteriorly, obovoid in shape (L/W ratio 1.1–1.2), dorsal shield without medial depression; muscle scars with weakly pronounced thickenings, located anterior and posterior to the postocularia; colour pattern unknown; gnathosomal bay Y-shaped, narrowing in posterior half; tips of Cx-I ending posterior to frontal margin; medial margin of Cx-IV not reduced to a median angle; Cx-III and -IV with a few longitudinal striae (two or three pairs on Cx-IV) Palp (Fig. 31 D): P- 1 without a dorsal seta; P- 2 with slightly concave ventral and convexly bowed dorsal margin; P- 3 ventral margin slightly concave; P- 4 equally narrowing from the base to distal edge. Legs: I-L (Fig. 31 E) with I-L- 6 dL/H ratio 3.2; IV-L: Fig. 31 F. Discussion: Differing from all known species of the genus in the obovate idiosoma shape. Distribution: Liberia (Cook 1966).Published as part of Pešić, Vladimir, Cook, David, Gerecke, Reinhard & Smit, Harry, 2013, The water mite family Mideopsidae (Acari: Hydrachnidia): a contribution to the diversity in the Afrotropical region and taxonomic changes above species level, pp. 1-75 in Zootaxa 3720 (1) on page 53, DOI: 10.11646/zootaxa.3720.1.1, http://zenodo.org/record/28502
Tiramideopsis Cook 1967
No full textGenus Tiramideopsis Cook, 1967 Type species: Tiramideopsis ovalis Cook, 1967 Diagnosis: Idiosoma noticeably elongated; surface of dorsal shield with a U-shaped ridge; posterior suture lines of Cx-IV lightly developed and closely flanking the genital field; Cx-IV meeting medially to form a well developed suture line; well developed ridges extending anteriorly from region of insertion of IV-L; Cxgl- 2 closely flanking either middle or anterior end of genital field; no condyles associated with openings for insertion of IV-L; 4–7 pairs of Ac; small setae flanking acetabula on separate platelets in female and with enlarged setal bases, lying on ventral shield in male; swimming setae absent; palp uncate; sexual dimorphism of idiosoma, legs and palp may be present in the different species. Remarks: This is a highly distinctive clade rather distantly related to the other mideopsid genera. It includes two subgenera, Tiramideopsis (four pairs of Ac and a slight sexual dimorphism of IV-L- 3 of male) and Navamideopsis (six or seven pairs of Ac and sexual dimorphism of ventral shield and palp in male). Distribution: India, Arabian Peninsula.Published as part of Pešić, Vladimir, Cook, David, Gerecke, Reinhard & Smit, Harry, 2013, The water mite family Mideopsidae (Acari: Hydrachnidia): a contribution to the diversity in the Afrotropical region and taxonomic changes above species level, pp. 1-75 in Zootaxa 3720 (1) on pages 8-9, DOI: 10.11646/zootaxa.3720.1.1, http://zenodo.org/record/28502
Djeboa bomiensis Cook 1966
No full textDjeboa bomiensis (Cook, 1966) (Figs. 10 A–F) Mideopsis (Djeboa) bomiensis Cook 1966: 239. Material examined: Type series: FMC, Liberia; holotype female, Suehn road, approximately four miles north of Bomi Hills Road, 30.xi. 1957 Cook (Coll. 84); paratypes: same site and date as holotype 3 / 3 /0; Coll. 36, 1/0/0; Coll. 41, 1/0/0; Coll. 76, 0/ 1 /0; Coll. 83, 3/ 1 /0; Coll. 88, 1/ 4 /0; Coll. 89, 0/ 2 /0; Coll. 91, 0/ 1 /0; Coll. 93,3/ 2 /0; Coll. 94, 2/ 3 /0; Coll. 95, 1/ 2 /0; Coll. 96, 1/ 2 /0 (see Cook 1966 for more details). General features: Dorsal shield oval (L/W ratio 1.1–1.2), with medial depression (Fig. 10 A); muscle scars with slightly pronounced thickenings, located anterior and posterior to the postocularia; dorsal shield blue in colour except periphery; gnathosomal bay of a modified Y-shape, noticeably narrowing in posterior half; tips of Cx-I ending posterior to frontal margin; medial margin of Cx-IV reduced to a median angle; Cx-III and -IV with a few longitudinal striae (two pairs on Cx-IV). Palp (Fig. 10 D): P- 1 without a dorsal seta; P- 2 with straight ventral and convexly bowed dorsal margin; P- 3 maximum height proximally, ventral margin concave; P- 4 equally narrowing from the base to tip. Legs: I-L (Fig. 10 E) with I-L- 6 L/H ratio 2.6; IV-L: Fig. 10 F. Discussion: In shape and setation of palp (with P- 1 lacking seta), Djeboa bomiensis is similar to D. rotundata K. Viets, 1914. The latter differs most noticeably in the rounded shape of the idiosoma, and also in a more slender P- 3 and P- 4 (Cook 1966). A re-examination of type material shows that the statement of Cook (1966) that swimming hairs are absent in D. bomiensis (followed later in the key of K.O.Viets 1970) is erroneous. Distribution: Liberia, widely distributed and numerous.Published as part of Pešić, Vladimir, Cook, David, Gerecke, Reinhard & Smit, Harry, 2013, The water mite family Mideopsidae (Acari: Hydrachnidia): a contribution to the diversity in the Afrotropical region and taxonomic changes above species level, pp. 1-75 in Zootaxa 3720 (1) on page 22, DOI: 10.11646/zootaxa.3720.1.1, http://zenodo.org/record/28502

General features: Dorsal shield almost perfectly circular (L/W ratio 1.0), with extended medial depression occupying most of the shield (Fig. 25 A); muscle scars located anterior and posterior to the postocularia, with moderately pronounced thickenings; anterior and central portion of dorsal shield blue; edges of ventral shield with large serrations; gnathosomal bay Y-shaped, noticeably narrowing in posterior half; tips of Cx-I ending posterior to frontal margin; medial margin of Cx-IV reduced to a little more than median angle; Cx-III and -IV with a series of longitudinal striae (three pairs of on Cx-IV). Palp as shown in Fig. 25 D: P- 1 with a dorsal seta; P- 2 with straight ventral and convexly bowed dorsal margin; P- 3 proximally thicker than distally, ventral margin with an proximal inflation, distally slightly concave; P- 4 slender, equally narrowing from the base to tip. Legs: I-L (Fig. 25 E) with I- L- 6 dL/H ratio 2.6–2.7, ventral margin distally convexly protruding; IV-L: Fig. 25 F. Remarks: In the round idiosoma shape, D. liberiensis resembles D. multidentata (K. Viets, 1911) which differs in possessing a patch violet in colour on the anterior dorsum and larger dimensions (Cook 1966). Distribution: Obviously the most frequently collected and most widely distributed species in Liberia.Published as part of Pešić, Vladimir, Cook, David, Gerecke, Reinhard & Smit, Harry, 2013, The water mite family Mideopsidae (Acari: Hydrachnidia): a contribution to the diversity in the Afrotropical region and taxonomic changes above species level, pp. 1-75 in Zootaxa 3720 (1) on page 45, DOI: 10.11646/zootaxa.3720.1.1, http://zenodo.org/record/28502

Palp (Fig. 19 D): P- 1 with a dorsal seta; P- 2 strongly inflated, with straight ventral and convexly bowed dorsal margin; P- 3 much higher proximally than ventrally, ventral margin slightly concave, dorsal margin strongly convex; P- 4 slender, basally thickened, from here to anterior tip equally narrowed. Legs: I-L (Fig. 19 E) with I-L- 6 L/H ratio 2.0, ventral margin distally convexly protruding; IV-L: Fig. 19 F. Discussion: The present species is similar to Djeboa compressa K.

General features: Dorsal shield oval (L/W ratio 1.1), with medial depression; muscle scars with little pronounced thickenings, located anterior and posterior to the postocularia; colour pattern consisting of an anterior blue patch (Figs. 40 K–L); gnathosomal bay Y-shaped, noticeably narrowing in posterior half; tips of Cx-I ending posterior to frontal margin; medial margin of Cx-IV reduced to a median angle; Cx-III and -IV with a series of longitudinal striae (four or five pairs on Cx-IV). Palp (Fig. 34 D): P- 1 with a dorsal seta; P- 2 with straight ventral and convexly bowed dorsal margin; P- 3 proximally thicker than distally, ventral margin concave; P- 4 slender, equally narrowing from the base to tip. Legs: I-L (Fig. 34 E) with I-L- 6 L/H ratio 2.0– 2.3, ventral margin strongly protruding; IV-L: Fig. 34 F. Remarks: The dorsal colour pattern of D. unimaculata resembles that of D. multidentata K.
