Lasioseius quinisetosus Lindquist & Karg
No full textLasioseius quinisetosus Lindquist & Karg (Figs 35–43) Lasioseius quinisetosus Lindquist & Karg in Christian & Karg, 2006: 128 (replacement name for Cheiroseius inguinalis Karg, 1977: 299, junior homonym of Lasioseius inguinalis Karg, 1976: 533). Cheiroseius inguinalis Karg, 1977: 299. not Lasioseius inguinalis Karg, 1976: 533. Diagnosis: The adult female of this species resembles those of several species of Lasioseius described from the Southern Hemisphere (Africa, Australia, South America) in having the metapodal plates coalesced into one enlarged, subtriangular, reticulated plate on either side. It further resembles that of L. uluguruensis van Aswegen & Loots, 1969, in distinction to other species including L. inguinalis Karg, 1976, in having only 4 (instead of 5 or 6) pairs of opisthogastric setae plus the 3 circum-anal setae on the ventri-anal shield, leaving setae ZV 3, JV 4, JV 5 on soft cuticle flanking that shield. It differs from L. uluguruensis and others in lacking discrete platelets on the pre-sternal region and in having nearly all of the dorsal shield setae smooth, attenuate (only j 1 and r 3 are tricarinate) and relatively long, most of them clearly longer than distance to insertion of next seta in series. Adult female. Dorsal idiosoma (Fig. 35): Dorsal shield 580–588 µm long, 425–465 µm wide at midlength level of setae s 6, embossed-reticulate over entire surface, lacking puncta posteriorly between setae Z 4 -J 5; with 22 pairs of setae (j 1 -j 6, z 1 -z 6, s 1 -s 6, r 2 -r 5) on anterior region and 15 pairs of setae (J 1 -J 5, Z 1 -Z 5, S 1 -S 5) on posterior region. Setae j 1 (40–43 µm) and r 3 (50–52 µm) lanceolate-tricarinate, all other dorsal shield setae slender, attenuate, most of them relatively long (58–88 µm), clearly longer than distance to insertions of next seta in series, though some of them, especially z 1, s 1, s 2, r 2, J 5 (20–32 µm) and to lesser extent z 2, z 5 (35–42 µm), shorter; seta r 4 ca. 0.6 as long as s 4 neighboring it medially; insertion of seta z 5 displaced slightly anterior to level of j 5. Lateral soft cuticle with 12 to 15 pairs of setae, including 7 marginal pairs (r 6, R 1 -R 6) and 0 to 3 submarginal pairs (UR) below R 4 -R 6, flanked by 5 pairs of opisthogastric setae ventrolaterally (see below), these setae attenuate, of moderate length. Ve nt r a l idiosoma (Fig. 36): Tritosternal laciniae free for ca. 80 µm of their length (115–120 µm). Presternal area strongly lineate, not microtuberculate, and containing first pair of sternal setae. Sternal shield densely punctate over most of surface, lineate-striate along lateral margins, lacking anteromedian patch of reticula, with second and third pairs of sternal setae and 2 pairs of poroids. Metasternal plates subquadrate, with fourth pair of sternal setae and third pair of poroids. Endopodal strips well formed alongside coxae III–IV. Genital shield truncated posteriorly, slightly widened behind genital seta, coarsely punctate over much of surface, slightly reticulate posteriorly; paragenital pores in soft cuticle well posterior to level of genital seta. Post-genital platelets consolidated into one transverse strip. Metapodal plates undivided, enlarged, reticulate, subtriangular, longer (85–97 µm) than wide (67–75 µm). Ventri-anal shield much wider (338–342 µm) than long (200–220 µm), with anterior margin slightly concave medially, embossed-reticulate over entire surface, lacking field of puncta in anal region; shield with 4 pairs of opisthogastric setae (JV 1 -JV 3, ZV 2) plus 3 circum-anal setae of which para - anals subequally as long as post-anal seta (25–30 µm); JV 3 (55–57 µm) clearly longest of setae on shield. Ventral soft cuticle around ventri-anal shield with setae ZV 1 flanking shield anteriorly and with 8 to 11 pairs of setae flanking shield postero-laterally, including 5 pairs of opisthogastric setae (ZV 3 -ZV 5, JV 4, JV 5) flanked by marginals R 4 -R 6 and 0-3 pairs of submarginals; other than short ZV 1 (20 µm), all these setae moderately long, similarly attenuated, and individually inserted on sclerotized tubercles. Exopodal plate a wide continuous strip alongside coxae II–IV. Peritrematal shield and peritreme (Figs 35–36): Peritrematal shields fused to dorsal shield at level of setae r 2 and contiguous with exopodal shields alongside coxae II–IV; peritremes extending anteriorly to bases of setae j 1. Spermathecal apparatus (Fig. 37): Difficult to discern, apparently with a small (length 8 µm, width 8 µm) but well sclerotized cup-shaped calyx; embolus and minor duct barely discernible. Gnathosoma (Figs 38–41): Anterior margin of tectum with 3 weakly formed, irregularly denticulate prongs, the central one deeply subdivided in some specimens. Middle segment of cheliceral shaft elongate, much as in species of Cheiroseius (length ca. 190 µm, including the ca. 50 µm long fixed digit). Fixed cheliceral digit with short pilus dentilis, 2 offset subapical teeth beside a deep notch (to accomodate apical hook of movable digit) anterior to a row of ca. 15 minute teeth inserted on a convex ridge (ca. 11–13 µm in length) that apposes dentition of movable digit (much as in species of Cheiroseius); movable digit (length 48–52 µm) tridentate, the central tooth larger; lateral hyaline rim along paraxial face of digit weakly serrated at level of base of movable digit. Deutosternum with 7 connected rows of fine denticles; anterior 5 rows each with ca. 25 denticles; 6 th and 7 th rows each with ca. 30 denticles. Hypostomatic setae h 1 slightly thicker, longer (48–52 µm) than h 2 (38–45 µm); internal mala slightly longer than corniculus, with lateral margin finely fringed. Palptrochanter with internal seta attenuated (35–40 µm), much longer than external seta (25 µm). Legs (Figs 42, 43): Leg I subequally as long as dorsal shield, leg IV slightly (1.1–1.2) longer (550–610 and 625–675 µm long, respectively); pretarsus of leg I long, thin (25–27 µm), pretarsi of legs II–III (15 µm) and IV (17–18 µm) shorter; claws of tarsus I smaller than those of other tarsi; tarsi II–IV with apical setal processes nearly half as long as pretarsi; pretarsi II–IV with thin attenuate paradactyli projecting well beyond apices of claws (15–17 µm on II–III, 20–25 µm on IV). Genua and tibiae of legs I-II-III-IV with 13 - 11 - 9 - 9 and 13 - 10 - 8-10 setae, respectively, without deficiencies. Tarsus II with seta pl - 2 elongated (55–60 µm) but short of reaching base of pretarsus (Fig. 43); tarsi III–IV without elongated setae. Tarsus IV (250–255 µm) ca. 1.4 as long as tarsi II–III (175–180 µm); leg IV setae pd - 3 on basitarsus and pd - 2 on telotarsus subequal in length (38–45 µm), ca. 0.5 as long as tibia (80–90 µm). All leg setae smooth. Adult male: Unknown. Material examined: Piracicaba – 3 female, 04.i. 1999, from litter of a patch of secondary forest. Previous records: Originally recorded from nematode probes from two sites in Chile, from substrate amidst grass roots and from algae of small pond (Karg 1977). Remarks: Although described as a species of Cheiroseius, some of the attributes in the original description of Karg (1977) indicate the proper placement of this species in the genus Lasioseius, especially: the tricarinate form of the humeral seta r 3, the position of the para-anal seta beside (rather than behind) the anal opening, the greater length of the post-anal seta relative to the para-anals (generally shorter than the paraanals in Cheiroseius), the enlargement of the metapodal plates (otherwise unknown among the many species of Cheiroseius and other platyseiine genera), and the rounded form of some of the pulvillar elements of tarsi II–IV that are typically acute in platyseiines. The examination by one of us (EEL, 2004) of a paratype female of Cheiroseius inguinalis confirmed the presence of other attributes characteristic of Lasioseius rather than Cheiroseius, including: the lack of flagellate-straplike form of the anterior hypostomatic seta and internal palptrochanter seta; the lack of straplike form of elongated seta pl - 2 on tarsus II and the lack of similar elongation and form of seta ad - 3 on tarsi II–IV, and a leg chaetotaxy fully holotrichous like most Lasioseius and other genera of Blattisociinae, rather than lacking seta v 3 on femora I–II and pv - 1 on genu II, which are definitive losses for genera of Platyseiinae (Lindquist & Evans 1965). When Christian & Karg (2006) transferred Cheiroseius inguinalis Karg into Lasioseius, as Lasioseius inguinalis (Karg 1977), this name became a junior homonym of Lasioseius inguinalis Karg, 1976, which is the name for another, quite distinct species also described from Chile. One of us (EEL, 2004) has examined the holotype of this species also (Figs 44–46). Adult females of this form have similarly enlarged metapodal plates but are distinct as follows: the caudal region of the dorsal shield and anal region of the ventri-anal shield are densely coarsely punctate (puncta not shown in Fig. 44, see fig. 19 c in Karg 1976); the dorsal shield setae are generally shorter and tricarinate-serrate; the sternal shield has a V-shaped patch of reticula anteromedially; the ventri-anal shield bears 6 pairs of opisthogastric setae (not 7 pairs as indicated by Karg, as JV 5 is inserted on a tubercle in soft cuticle beside the incurved postero-lateral margin of the shield) (Fig. 44); the cheliceral digits are smaller and with much different dentition, the fixed digit having 6 coarse, well separated teeth, and the movable digit (length 30 µm) quadridentate (Fig. 45); the legs are shorter, with I and IV shorter than the idiosomal length (which is similar to that of Ch. inguinalis), and with the tarsi markedly shorter (tarsi II–III 110–115 µm, IV 160 µm); the pretarsi of legs II–IV have short paradactyli (Fig. 46). As a result, L. inguinalis (Karg 1977), was replaced by Lasioseius quinisetosus Lindquist & Karg in Christian & Karg, 2006: 128, and that name is used here.Published as part of De, Jeferson L., Lindquist, Evert E. & De, Gilberto J., 2009, Edaphic ascid mites (Acari: Mesostigmata: Ascidae) from the state of São Paulo, Brazil, with description of five new species, pp. 1-32 in Zootaxa 2024 on pages 17-19, DOI: 10.5281/zenodo.18613

Fungiseius Moraza & Lindquist, 2011, new genus
No full textFungiseius new genus (Figs 1–60) Type species: Fungiseius armatus new species Diagnosis. Adults of Fungiseius are distinguished apomorphically from those of other blattisociine genera by the following attributes: dorsal shield with lateral margins bearing a delineated strip extending from setae z 2 to S 5 and bearing some of r -marginal setae anteriorly and the series of S - lateral setae posteriorly; sternal or sternitigenital shield with gland pore at apex of endopodal extensions between legs I and II; female with small ventrianal or anal shield; female with deep postgenital furrow; male and female with deep postanal furrow and lacking opisthogastric setae JV 3; hypostomatic setae hp 2 minute; legs II greatly thickened, and with enlarged, curved, spine-like setae on dorsolateral surfaces of tarsus; genua III and IV with eight and nine setae respectively, lacking pv - 1; tarsus I with one dorsobasal seta pd attenuate, erect; claws on legs I–IV with a basal swelling. Among the genera of Blattisociinae, adults of Fungiseius are strikingly similar to those of another fungus-inhabiting genus, Hoploseius, in having legs II greatly thickened and provided with spine-like setae. In contrast to Fungiseius, leg II of Hoploseius has enlarged spine-like setae on the ventral faces of the femur, genu, tibia and tarsus, and lacks enlarged curved setae on the dorsolateral face of the tarsus. Adults of Hoploseius differ in other apomorphic ways from those of the new genus in having the apical margin of the fixed cheliceral digit with a curved row of small, rasping teeth; females with an expansive ventrianal shield; genu I lacking setae pd - 3 and av - 2, and genua III-IV retaining seta pv - 1, although lacking al - 2.

Leg setae collectively smooth. Legs of male without dimorphically modified setae. Etymology. The name of the genus is a Latinized combination of the term fungus, meaning fungus, and seius or sejus, a Roman surname commonly used by authors to form names for genera of mesostigmatic mites. The name is masculine in gender, and indicates the habitat from which these mites have been collected. Distribution and habitats. This genus is based on material associated with perennial fungal growths on decaying logs in two widely separated, subtropical to tropical New World localities, one from pine-oak forest south of the Isthmus of Tehuantepec in Mexico, and one from a locality in coastal lowland rainforest of Costa Rica. Remarks. The genus Fungiseius is based on their adults having several apomorphies, some of which appear to be unique among the known taxa of Blattisociidae: (1) dorsal shield with delineated lateral rim extending from setae z 2 to S 5 and bearing z 2 or s 2, r 2 -r 5, and S 1 -S 5; (2) apex of endopodal extension of sternal or sternitigenital shield between legs I and II with a gland pore; (3) female with deep postgenital furrow; (4) male and female with deep postanal furrow; (5) opisthogastric setae JV 3 absent; (6) hypostomatic setae h 2 minute; (7) legs II much stouter than other legs; (8) strongly thickened claw-like setae on tarsi of legs II to IV, especially leg II; (9) genua of legs III–IV lacking seta pv - 1. Attributes (1), (3), (4) and (8) appear to be unique to this genus. Although attribute (1) is superficially similar to a condition found in Orthadenella, the latter genus does not belong to this subfamily, in view of its females not having an apparently phytoseioid-type spermathecal system (Athias-Henriot 1973; see discussion below). Also, the delineated rim of attribute (1) in Fungiseius is unique in carrying lateral setae S 1 -S 5, leaving the R - marginals on soft cuticle, while the rim found in Orthadenella and among genera of the ascoid family Melicharidae differs in bearing most or all of the R - marginal setae, with the laterals inserted mediad the rim (personal observations). Attribute (7) is shared only with Hoploseius, whose members are also restricted to bracket fungi. Attributes (2) and (6) are uncertainly unique in that their presence or absence among other taxa of this and related families has not been confirmed, while (5) and (9) are homoplastic. The apomorphic attribute of a “phytoseioid-type” sperm access system in adult females, on which the superfamily Phytoseioidea is based (Athias-Henriot 1968, 1971; Alberti & Di Palma 2002; Lindquist et al. 2009), is difficult to observe in both species of Fungiseius, due to the reduced size and relatively weak sclerotization of the calyx, such that discernment of a minor duct emanating from the embolus is problematical. However, other, more readily observable attributes detailed by Lindquist & Moraza (2010) as diagnostic for the family Blattisociidae support placement of Fungiseius in this family. Among the genera of Blattisociinae, adults of Fungiseius are strikingly similar to those of Hoploseius, whose members also dwell in bracket fungi, in having greatly thickened legs II. However, this appears to be an interesting case of convergence. Legs II of Hoploseius bear strongly thickened, spine-like setae on the ventral faces of the femur, genu, tibia and tarsus; these setae are apposed to one another, apparently for grasping structures, most probably those of the drosophilid flies used for phoresy (Lindquist 1963). As adult males are similarly armed, but have not been found to be phoretic, the grasping function may also be used by both sexes in copulation. In contrast, legs II of both sexes in Fungiseius have slender setae on the ventral faces of the femur and genu; strongly spine-like setae are restricted to the tarsus, primarily on the dorsal and lateral faces. The latter setae are claw-like, not apposable, and probably are used for scraping or burrowing. Other than a within-genus tendency towards hypotrichy among some of the leg segments, which is subject to considerable homoplasy, members of these two genera do not share other apomorphic attributes that would indicate a sister-group relationship. Even the loss of seta pv - 1 on genua III and IV in Fungiseius differs from the losses of setae al - 2 and av - 1 on genu III and of pd - 3, al - 2, and pl - 1 on genu IV among some species in Hoploseius (Lindquist & Evans 1965). The affinity of Hoploseius with Lasioseius, based on the tricarinate form of at least some of the dorsal shield setae and the strongly formed ventrianal shield, is distinct from Fungiseius. Among other genera of Blattisociinae, adult females of Fungiseius are similar to those of Aceodromus and Opilioseius in having a reduced ventrianal shield or an anal shield, and in the spermathecal apparatus having a weakly sclerotized calyx. These attributes are subject to considerable homoplasy among other genera of this subfamily, especially the species-rich Lasioseius (personal observations).Published as part of Moraza, María L. & Lindquist, Evert E., 2011, A new genus of fungus-inhabiting blattisociid mites (Acari: Mesostigmata: Phytoseioidea) from Middle America, with a key to genera and subgenera of the subfamily Blattisociinae, pp. 1-25 in Zootaxa 2758 on pages 4-6, DOI: 10.5281/zenodo.27675

Dear Club Members
Thanks for your swell letter I received from you and as I received it after a week of no mail it was doubly welcome. I am at the present in the hospital getting over an eye infection and it sure is painful. In Europe they have bullets to watch out for and over here we have that plus diseases. We have been very busy here and have been on the go all the time. I had a chance to knock off a few weeks furlough during March and although I did get to a city it is a bad place for a furlough. I am hoping for a return to the states the latter part of this year and am starting to sweat it out now. That good old uncle sugar looks so good from here that it will be like a trip to heaven. Well no more here but will write later.

No full textMakarovaia new genus (Figs 1–40, 98– 100) Type species. Makarovaia ornata new species. Genus based on adult female, male, nymphal and larval material representing one newly described species. Diagnosis. Adults of Makarovaia are distinguished from those of Hispiniphis in having the dorsal shield more extensive anterolaterally, so as to bear setae z 2, s 1, s 4, r 2, r 3, and in having more strongly sclerotised and ornamented shields on the venter, including a moderately large, obovate anal shield slightly wider than long. Male sternigenital shield fully formed, with endopodal extensions between leg bases, a convex posterior margin between bases of legs IV, and bearing all five pairs of sternal setae. Hypostome of nymphs and adults elongate, resulting in corniculi inserted relatively posteriorly, at level about halfway between insertions of hypostomatic setae hp 1 and hp 3. Movable cheliceral digit of female and female nymphs multidenticulate (≥four teeth), and with bluntly pointed process distinct on midventral face. Male chelicera with ciliated, flexible, digitiform process paraxially at level where movable digit hinged to fixed digit, and with spermatodactyl abruptly bent downward near it base, directing the freely extending part posteroventrally. In addition to leg chaetotactic reductions noted for the genusgroup description, genua II and III lacking ventral setae (av absent); femora I–II and tibia I retaining seta ad - 3, genu II retaining al - 2. Tarsus I without ventrodistal acuminate process extending under pretarsus; tarsi II–IV with ventral projection under pretarsus acuminate in immature instars but truncate in adult. Nymphs with opisthosoma normal in fully-developed form, size, and not closely flanked by legs IV, which directed posterolaterally. Description. Idiosomatic dorsum. Adult female (Fig. 1). Dorsal shield well sclerotised, sufficiently expansive anterolaterally to bear setae s 1, z 2, r 2, r 3; surrounding soft cuticle thickly formed and ornamented, in distinction to simply striated ventral cuticle, as noted for family. Dorsal shield with maximum complement of 18 pairs of setae, including 12 podonotal (j 1, j 3 –j 6, z 2, z 4, z 5, s 1, s 4, r 2, r 3) and six opisthonotal pairs (J 4, J 5, Z 2 –Z 5); dorsal setae similar in form and general size except J 5 always minute. Dorsal shield with complement of 17 pairs of discernible pore-like structures (nine podonotal, eight opisthonotal), of which five pairs (three podonotal, two opisthonotal) superficially appear secretory (gland pores) and 12 pairs (six podonotal, six opisthonotal) non-secretory (poroids). Soft lateral cuticle with ca. 20–25 pairs of lateral and marginal setae (s 5, s 6, r 5, S 1 –S 5, R 1 –R 6, and six or more UR ’s), and at least six pairs of marginal poroids, including idRp. Adult male (Fig. 21). Dorsal shield similar in size, ornamentation and setation to that of female; form and relative lengths of setae on dorsal shield and dissimilar structure of surrounding soft cuticle as in female.

Tarsi II and III with setae ad - 1, pd - 1 as long as short pretarsus; apical ventral tarsal process triangular. Etymology. The generic name is in honor of our esteemed Russian colleague, Olga Makarova, whose many contributions to the systematic and ecological knowledge of gamasine mites are exemplary. Distribution and habitats. The new genus is currently based on one newly described species. All instars of mites of the genus Makarovaia are known only as subelytral symbionts of adult hispine beetles of the genus Chelobasis, tribe Arescini. Only four species of the neotropical genus Chelobasis are recognised; their larvae are all restricted to unfurled leaves of Heliconia (Strong 1977; Staines 2009). Remarks. The larval and protonymphal complement of four dorsal setae on femur I differs from the general pattern given by Evans (1963) in having two anterodorsals and two posterodorsals, instead of three and one, respectively. This is probably a posterolateral shift in position of one of the more basal dorsal setae, rather than an unlikely ontogenetic retardation of one anterodorsal seta and acceleration of one posterodorsal seta. Adult males of the one known species of Makarovaia have a peculiarly formed structure at the base of the movable cheliceral digit. Quite slender, finely ciliated, and apparently flexible, it seems to be an outgrowth from the paraxial surface of the arthrodial envelope (Fig. 24). A somewhat similar but more strongly elaborated excrescence, restricted to males, has been illustrated for many free-living parasitid mites (Micherdzinski 1969); otherwise, such a structure has not been noted or illustrated among males of other families of Gamasina, although it may be readily overlooked. Similar or more elaborate arthrodial brushes are evident among members of the families of Eviphidoidea, but they are featured on immatures and adults of both sexes. The structure is not formed in the immatures or adult female of Makarovaia ornata, and is not evident among members of the species of the sister genus Hispiniphis at hand. Adult males of the one known species of Makarovaia are frequently infected with an undescribed form of the laboulbeniaceous genus Rickia (see discussion). Adults of species of Hispiniphis have rarely been found infected with this fungus, despite the coexistence of the beetle hosts.Published as part of Moraza, María L. & Lindquist, Evert E., 2015, Systematics and biology of mites associated with neotropical hispine beetles in unfurled leaves of Heliconia, with descriptions of two new genera of the family Melicharidae (Acari: Mesostigmata: Gamasina: Ascoidea), pp. 301-351 in Zootaxa 3931 (3) on pages 311-315, DOI: 10.11646/zootaxa.3931.3.1, http://zenodo.org/record/24418
