Grieshuber’s (2014) following statements do not help much in distinguishing this species from C. wanda in many cases: 1) size usually larger than C. wanda [but very often there is no difference in size between the two species]; 2) male hindwing underside dark submarginal spots obsolete or absent [such feature is frequently found in C. wanda too]; 3) female upper side never dark as in C. wanda [some dark females of C. arida could be as dark as some light females of C. wanda, such as Specimens B 1 in fig. 2 and C 1 in fig. 3, but this character is usually useful; on the other hand, female of C. wanda yangguifei R.-X. Huang & Murayama, 1992 (= C. chrysotheme yangguifei: Grieshuber & Lamas 2007; treated as C. stoliczkana yangguifei by Hoshiai 1993) seems to break this rule greatly, discussed below in details]; 4) style of flight being more straight and a bit higher above the ground, not so zigzag and near the ground as in C. wanda [such difference is only evident at a sympatric locality on Road from Caka to Tianjun as Grieshuber et al. (2012: 58) observed, however it has no absolute use for the specimens from other localities; the junior author observed that C. arida at Aksai flew very near the ground, C. wanda at Niuxinshan, Qilian flew much higher above the ground, C. wanda at Dulan flew high above the ground and often fell suddenly to the ground; the senior author observed that C. wanda at Demula, SE Tibet could fly in straight line; it seems that both C. wanda and C. arida fly higher at the biotopes with bushes but lower at the biotopes with only grasses]. Moreover, it is noted that size of cell spot on hindwing underside and red markings around cell spot are also individually variable and useless in distinguishing the two species. Giving a limit for the populations from Qinghai and Gansu only (C. arida cakana and C. wanda wanda), the following characters are found useful in distinguishing the two species: 1) male upper side ground color is more with an orange hue in C. arida than in C. wanda - this is often useful for a close examination of specimens, but useless for photos; 2) female upper side black markings are often deeper and more in contrast with the pale ground color in C. arida than in C. wanda, but sometimes some females of C. arida could approach C. wanda in dull black markings; 3) females with pale ground color at subbasal area of forewing upper side all belong to C. arida; 4) female hindwing underside submarginal spots are more uniform in color and less in contrast with the pale ground color in C. arida, but are usually uneven in color and more in contrast with the pale ground color in C. wanda. These characters also work for C. arida arida from W. Kunlun Shan, W. Xinjiang, various populations of C. wanda wanda from Tibet and C. wanda demula Huang, 2021 from Demula, SE. Tibet. However, C. wanda yangguifei from E. Xinjiang seems to break this rule completely, being in common with C. arida arida and C. arida cakana but entirely different from C. wanda wanda and C. wanda demula in all the above-mentioned characters. Notes on Colias wanda yangguifei. By the help of Dr. X. Zhang (Urumqi), the senior author examined the photos of the holotype of C. wanda yangguifei (Fig. 73). C. wanda yangguifei was originally described as C. chrysotheme yangguifei on 5 ♂♂ and 2 ♀♀ from “Aqikfu, Aljin, East Kunlun (meaning the contiguous area between Aljin and East Kunlun)”, with 1 ♂ and 1 ♀ figured (R.-X. Huang & Murayama 1992: 2, figs. 7–8). R.-X. Huang & Murayama (1992) did not indicate the status of the figured specimens. This pair of specimens were traced and photographed by Dr. X. Zhang who visited Prof. R.-X. Huang a few years ago. According to Dr. X. Zhang (pers. comm.), this pair of type specimens were not labeled at all (the senior author visited Prof. R.-X. Huang in 1993 and found that he used to give no label to many specimens kept in his collection, and often changed the labels of the specimens exchanged to him). However, they fit the original figures except for the antennae glued from other specimens. The female paratype (Fig. 74) is actually a C. chrysotheme (Esper, [1781]) as Hoshiai (1993) indicated. The type locality of C. wanda yangguifei is clarified as follows. R.-X. Huang (1986) gave the collecting data of C. wanda yangguifei (misidentified by him at the time as Colias fieldii) in his early publication as: Kalachuka Shan, East Kunlun, 4350m on 23.VII.1984 at grassy slopes. Zhang et al. (1986) published a brief overview of the 1984 expedition joined by R.- X. Huang and gave a detailed map of the routes and spots explored. Kalachuka Shan is situated to the SE. of Aqikfu lake and a camp is marked at the foot of the mountain, near the co-ordinates 36.9365N, 88.6674E. The holotype from Kalachuka Shan, more like a male of C. wanda wanda from E. Kunlun Shan, Qinghai, appears not so bright as in specimens from the Aljin Shan area between Ruoqiang and Mangai. By the help of Mr. R. Xing (Urumqi) and Mr. Z.-Y. Qi (Shanghai) the senior author examined a few specimens from Aljin Shan and Qimantag Shan, in addition to the specimens figured in literature (Grieshuber et al., 2012; Grieshuber, 2014); these newly collected specimens are in common with Grieshuber’s (2014) specimens in detail. However, Dietz (2002: 95, figs. 1 & 4) figured a very dark female from a locality “ 125 km south of Miran” under the name, C. baeckeri, which cannot be distinguished from C. wanda wanda from Qinghai. It is noted that all these lately collected specimens are not topotypic, being obtained from the localities in Aljin Shan and Qimantag Shan, more than 150 km away from the type locality of C. wanda yangguifei. By these insufficient and contradictory data, the authors could not make a conclusion on the status of C. wanda yangguifei, leaving this to a further study in future. Without a further study on more topotypic specimens (especially ♀♀) from Kalachuka Shan, a final conclusion on the taxonomy of C. wanda yangguifei is impossible. The specimens from Aljin Shan and Qimantag Shan might not belong to C. wanda yangguifei, whilst the holotype of C. wanda yangguifei from Kalachuka Shan might belong to C. wanda wanda. Identification. Specimens from Wulan-Tianjun area, neighbouring to the type locality, are identical with the type specimens of C. arida cakana. Specimens from Aksai (previously recorded by Hoshiai 1996) are somewhat closer to the populations from W. Qilian Shan (named as C. arida muetingi, later treated as a synonym of C. arida cakana). However, the authors agree to Grieshuber & Lamas (2007) opinion that C. arida muetingi is not constantly different and does not merit being retained as a valid subspecies. Male specimens from Aksai tend to have an obsolete reddish marking alongside the cell spot on hindwing underside; female specimens from Aksai tend to have a paler ground color on hindwing upper side. As stated for the case of C. arida muetingi by Grieshuber & Lamas (2007), such variations are slight and not constant, and are more possibly caused by different climates rather than geographical isolation. Flight period. Early July to early August, depending on localities and years. It flies earlier at Wulan-Tianjun area than at Aksai in the same years. Altitude. 3400–3600m. Distributional notes. C. arida cakana and C. wanda wanda are sympatric in a few localities (Verhulst 1994a; Grieshuber et al. 2012). Our collecting data confirmed this at least at Guanjiaoshan, Tianjun where the two taxa were collected from the same locality on same days in early July. C. arida cakana seems not to be found to the east of Qinghai lake.Published as part of Huang, Hao & Song, Kui, 2022, A review of the genus Colias Fabricius, 1807 (Lepidoptera: Pieridae) from Qinghai with descriptions of a new subspecies of Colias thrasibulus Fruhstorfer, 1910, pp. 451-489 in Zootaxa 5105 (4) on pages 453-455, DOI: 10.11646/zootaxa.5105.4.1, http://zenodo.org/record/633377

Harpagophora arida Redman & Hamer & Barraclough 2003, sp. n.
No full textHarpagophora arida sp. n. Redman Figs 1, 20–26 Type material (examined): Holotype: NAMIBIA: 1ơ, Ais-Ais [2717CB], x.1968, R. F. Lawrence (AMSA uncatalogued). Diagnosis: Larger femoral spine apically bifid with two divergent points of unequal length (Fig. 24). In addition to two femoral spines, a third short tooth is present at flexure of telopodite (Fig. 24). Spine branch short, narrow, cylindrical and bifurcate, terminating in two spines of unequal length (Fig. 24). Pectinophore an elongate, ribbonlike laminate plate curving apically. Length of pectinophore about half length of posterior limb of telopodite (Fig. 24). Proximal margin of pectinophore dentate, while distal margin with several spiniform processes emerging closer to apex (Fig. 22). Distal margin of telocoxite with shallow depression over centre of distal surface (Fig. 22). Lateral margin of telocoxite folded back on itself (i.e. fold directed distally) in area around gonocoel opening (Fig. 22). Etymology: L. arida = dry. Refers to the arid, desert type habitat of the type specimen. Lawrence proposed the name (manuscript name) in 1968. Description: Dimensions: Male, n = 1. Body width 8.2; collum width 8.1; body length 80.0; legs detached and missing; antenna length 5.7. Number of segments: 54. Colour: Head and clypeus light brown. Collum brown laterally and light brown dorsally. Prozonites greyish (bleached), mesozonites light brown, metazonites brown.Anal valve, caudal spine, and legs brown, antennae light brown. First ozopore: Segment 6. Collum: Anterior corner rounded and obtuse; posterior corner extending a little beyond the posterior border and overlapping second segment. One submarginal groove with smaller groove along vertical margin (Fig. 20). Gonopods: Longer femoral spine directed distally and partially concealed under laterally directed fold on aboral surface of telocoxite, apically bifid with two divergent points of unequal length (Fig. 24). Short, simple, partially curved, second spine wrapped around base of larger femoral spine and directed laterally. A third small spine present at flexure of telopodite (Fig. 24). Pectinophore elongate, ribbon-like, curling distally. Length of pectinophore about half length of posterior limb of telopodite. Proximal margin of pectinophore dentate, while distal margin with several spiniform processes emerging closer to apex (Figs 22, 25). Spine branch short, narrow, cylindrical and apically bifid with two spines of unequal length, emerging halfway down telopodite (Fig. 24). Telocoxal spines obscure and aborally directed (Fig. 22). Distal margin of telocoxite simple, without medial protrusion but with shallow depression over centre of distal surface (indicated by arrow, Fig. 22). Lateral margin of telocoxite folded back on itself (i.e. fold directed distally) in area around gonocoel opening (indicated by broken arrow, Fig. 22). Gonocoel opening extending from opening where posterior limb of telopodite emerges, down lateral surface of gonopod. Aboral surface of telocoxite with shallow depression in which larger femoral spine rests (Fig. 22). Pre-anal ring: Caudal spine short, not extending beyond margin of anal valve, moderately upturned distally (Fig. 26). Distribution: The species appears to be endemic to southern Namibia (Fig. 1). Remarks: This species differs from congeners in the structure of the telocoxite, pectinophore and spine branch, and the lateral margin of the telocoxite which is curled upwards (i.e. fold directed distally) in the area around the gonocoel opening. The latter character state is unique to H. arida. The spine branch emerges closer to the flexure of the telopodite than in other Harpagophora species, where these structures (pectinophore and spine branch) occur in close proximity to each other. H. arida is bigger than the South African species of the genus.Published as part of Redman, Guy T., Hamer, Michelle L. & Barraclough, David A., 2003, Revision of the Harpagophoridae (Diplopoda, Spirostreptida) of southern Africa, including descriptions of five new species, pp. 203-277 in African Invertebrates 44 (2) on pages 215-217, DOI: 10.5281/zenodo.766630

No full textDiploglena arida sp. n. Figs 1–4, 14, 19, 26, 27, 48–50 Diploglena capensis Purcell, 1904: Platnick & JÄger 2008: 10, figs 26–30 (in part, misidentified). Etymology: The species is named for the arid habitats that it occupies in the Northern Cape Province of South Africa. Diagnosis: Males of D. arida sp. n. are most similar to D. capensis, but can be separated by the shape of the tegular apophysis (subtriangular as opposed to slightly curved distally), the clearly larger membranous conductor, and the relative orientation of the embolus and tegular apophysis: tips in the same transverse plane in D. arida sp. n., while the tegular apophysis is clearly more distal and further from the embolus tip in D. capensis (compare Figs 48–50 with Figs 51–53). Females are similar to D. dippenaarae sp. n., but can be separated by the narrow unsclerotised patch on the anterior epigynal plate, which is only as broad as the transverse sclerotised strips (as broad as the lateral margins of the posterior tracheal openings in the other species).

Carapace yellow-orange; chelicerae orange-brown; sternum and mouthparts orange, darker around margins; leg I and II yellow, metatarsi and tarsi yellow-orange, legs II–IV with creamy-yellow femora, remaining segments yellow; abdomen cream dorsally and ventrally. Palpal femora and patellae yellow, tibiae and tarsi yellow-orange. External genitalia with weakly sclerotised anterior plate, with broad arch-shaped unsclerotised patch in front of paired slightly recurved sclerotised strips (Fig. 14); ESTR 1:0.54–1:0.64.

Amphibolocypris arida Jocque, Brendonck, Riddoch & Martens, 2010, sp.nov.
No full textAmphibolocypris arida sp.nov. Jocque & Martens (Figs 2–5) Type locality: Rock pools near Thamaga, south-eastern Botswana (24 ° 40 ’ 30 ” S, 25 ° 31 ’00” E). The pools are situated on granite rocky outcrops, surfacing in a mainly savannah matrix of grasslands and shrubs. The pools are generally shallow (max 20 cm deep) and small (max. 2 m radius), with water temperature reaching up to 37.1 °C at mid day. Based on measurements in 8 pools, habitat waters were characterized by a basic pH varying between 7.3 and 8.8 and were always low in conductivity with values ranging from 27.6 to 69.1 µSm/cm (Jocque, unpubl.). Accompanying ostracod fauna: Heterocypris sp.nov., Heterocypris incongruens, Sarscypridopsis cf gregaria, Potamocypris spec. Type material: Holotype: a male, with soft parts dissected in glycerine in a sealed slide and with valves stored dry (after use for SEM) in a micropalaeontological slide (OC. 3167) Allotype: a female, with soft parts dissected in glycerine in a sealed slide and with valves stored dry (after use for SEM) in a micropalaeontological slide (OC. 3168) Paratypes: 2 males and 2 females, with soft parts dissected in glycerine in a sealed slide and with valves lost (OC. 3166, OC. 3169 -OC. 3171) Derivation of name: as the species is thus far only known from rock pools in a (semi-) arid area, the specific name refers to this characteristic of its habitat. Diagnosis: Valves elongated, with anterior margin more broadly rounded, posterior margin bluntly pointed, posterior calcified inner margin narrow, but present. External surface set with elongated microridges. Valves sexually dimorphic, with female valves being more elongated. Natatory setae on A 2 of medium length. T 2 with subapical seta claw-like, reaching middle of elongated end claw. CR without proximal seta. Hemipenis with one shield with one club-like expansion, the other shield with two elongated lobes, one pointed, basally inserted, and one distally rounded, more apically inserted. Prehensile palps almost symmetrical, relatively short, with broad base and sickle-shaped. Additional description of male: Valves in lateral view (Figs 2 A,B) elongated, weakly calcified, externally set with longitudinal micro-ridges and sparse rimmed pores (Figs 2 E,F = from female valves). with rounded dorsal margin, anterior margin more broadly rounded than posterior margin, ventral margin slightly sinuous. Valve outline antero-dorsally with a dent. Anterior calcified inner lamella broad, dorsally ending at dent; posterior calcified inner lamella narrow, but present. Muscle scars situated in front of the middle. Carapace in dorsal view very narrow, lancet shape. No overlap between LV and RV. A 1 (Fig. 3 A) with 7 segments. First segment with 2 ventral setae, no dorsal seta. Second segment with one medio-dorsal seta, Rome and Wouters organs not visible. Third segment more than twice as long and wide, with one shorter ventral and one longer dorsal seta. Fourth segment almost as long as wide, with 2 shorter ventral setae and 2 long dorsal natatory setae. Fifth segment slightly longer than wide, also with two shorter ventral and 2 longer dorsal natatory setae. Sixth segment almost twice as long as wide, with 1 short ventral setae and 4 long natatory setae. Terminal (seventh) segment more than twice as long as wide, with 1 shorter seta, one long aesthetasc Ya (not drawn) and 2 long natatory setae. A 2 (Fig. 3 B) with exopodite reduced to a small plate, bearing 1 long and 2 short setae. Endopodite 3 - segmented. First segment elongated and stout, aesthetasc Y short and club-like, distal part swollen. Natatory setae of unequal length, but all relatively short, mostly not reaching tip of second segment; ventral-most seta the longest. Second segment with 2 dorso-lateral and 3 ventro-lateral setae (2 long, 1 short), distal chaetotaxy typical of male Cyprididae, with setae z 2 and z 3 changed into claws, z 1 a seta and claw G 1 turned into a long seta, extending beyond tips of all claws, these claws stout, relatively short and set with strong spines. Terminal segment with claws G M and G m, seta g and aesthetasc y 3, basally fused with an accompanying seta. Md (compare to Figs 3 D,E,E’ = female) with coxal plate distally set with rows of spines and small setae. Palp with alpha-seta short, narrow and smooth, beta-seta short, stout and hirsute, gamma-seta short, broad and hirsute in distal fourth of its length. Second segment dorsally with a group of 3 smooth setae, ventrally with 3 long and smooth and 1 shorter and hirsute setae. Third segment dorsally with 4 subapical setae, ventrally with 1 subapical seta, distally with 3 normal setae and a gamma-seta. Terminal segment with 3 stout claws and 3 small setae. Mx 1 (compare to Fig. 4 A = female) with second palp-segment slightly spatulate, Zahnborsten on third endite smooth. T 1 (Figs 5 A, B) with 1 a-seta, 1 b- and 1 d-setae. Distal chaetotaxy of coxal plate consisting of 16 setae of sometimes very different shape and length. Prehensile palps almost symmetrical; first segments with large ventral protuberance, set with 1 large sensory organ; second segments sickle-shaped, tapering towards the end, distally with one long and stout sensory organ. T 2 (compare to Fig. 4 B= female) with elongated segments and unusually long setae. First segment with seta d 1 reaching into second segment, this (knee-) segment with seta d 2 missing. Third segment with 1 long ventro-apical seta, reaching almost to fifth segment. Fourth segment divided into two elongated subsegments: segment 4 a with a relatively short ventro-apical seta, not reaching tip of segment 4 b, this latter segment with 2 subequal, ventro-apical setae. Fifth (terminal) segment with 1 subapical seta and 1 subapical claw (generic character) and 1 long and thin apical claw. T 3 (compare to Figs 4 C,C’= female) a cleaning limb. First segment with 3 setae. Second segment with 1 long apical seta. Third segment with 1 short lateral seta. Distal part of third and fourth segment fused to a pincer shaped organ, bearing 1 long seta, 1 seta of medium length, set with two rows of setulae and 1 very short seta. CR (Fig. 4 E) distally with 2 claws and 1 apical seta, proximal seta missing (generic character). Attachment (Fig. 4 D = female) slender, with simple distal bifurcation. Hemipenis (Fig. 5 C) with a complex of ventral lobes of medial and lateral shields: one shield with one club-like expansion, the other shield with two elongated lobes, one pointed, basally inserted, one distally rounded, more apically inserted. Additional description of female: Female valves more elongated, dorsal margin bluntly pointed, with greatest height less than ½ the length and situated almost in the middle. Anterior margin more rounded than posterior margin, but both less so than in the male. Calcified inner lamellae and position of muscle scars as in the male. A 1, Md (Figs 3 D,E,E’), Mx 1 (Fig. 4 A) and T 3 (Fig. 4 C,C’) as in the male. A 2 (Fig. 3 C) with natatory setae slightly longer than in the male, z 1-3 all setae, reaching up to or beyond tips of end claws, the latter more slender and longer than in the male and set with more delicate spines. T 1 (Fig. 4 F) with palp short and wide, distally with 3 relatively short setae. T 2 (Fig. 4 B) with segments and setae slightly longer and more slender than in the male. CR slightly more slender than in the male. Remarks: Most species in the subfamily Isocypridinae are known to have weakly calcified valves. In the present study, most specimens of A. arida sp.nov. have either weakly calcified, or completely decalcified valves. This means that only few specimens had valves reflecting the true shape, hence the limited number of illustrations of these valves. The longitudinal ridges on the valve surfaces (Figs 2 E,F) could function as reinforcement of weakly calcified valves. Measurements (in mm): Male, holotype: RV, L = 1.69, H= 0.65; LV, L= 1.67, H= 0.65 Female, allotype: RV, L= 1.58, H= 0.63; LV, L = 1.58, H= 0.64 Differential diagnosis: Amphibolocypris arida sp.nov. differs from the other described species in the genus, the type species A. exigua, by the more elongated valves, with more pointed posterior margin, especially in the female; by the shape of the hemipenis (one large rounded lobe and one narrower lobe in A. exigua, one subquadrate lobe and three more elongated lobes in A. arida) and of the prehensile palps (proximal segments with more elongated ventral protuberances and more elongated and narrower distal segments with shorter distal sensory organs in A. exigua). Two further, as yet undescribed, species from Namibia (Martens, unpubl.) differ from both A. exigua and A. arida sp.nov. in the shape of the hemipenis (see below). Ecology and distribution: The species is presently known from its type locality only, namely rock pools on a granite outcrop in south-eastern Botswana. From other, as yet unpublished records of other species of Amphibolocypris from Namibia (see above), it would seem that this once monospecific genus might be more speciose than was previously assumed, in which case the individual species could have rather limited distributions. Other species investigated: As a comparison, two further new species of Amphibolocypris from the western part of southern Africa are mentioned here, and the outlines of the hemipenis given. Due to limitation of material (single specimen, completely decalcified valves), these species are left in open nomenclature.Published as part of Jocque, Merlijn, Brendonck, Luc, Riddoch, Bruce J & Martens, Koen, 2010, On Amphibolocypris arida sp. nov.
