D'après les schémas originaux de Antonio Berlèse c'est une femelle que nous voyons. La chaetotaxie est bien sur des protubérances comme ici.LINDQUIST AND EVANS : TAXONOMIC CONCEPTS IN THE ASCIDAE, with a Modified Setal Nomenclature for the Idiosoma of the Gamasina (Acarina; Mesostigmata)

Genus Hoploseius Berlese
Hoploseius BerIese, 1914, p. 136. Type-species: Zercon cometa Berlese (1910),
by original designation.
BODY DORSUM. Female with 32 to 42 pairs of .setae: 16 to 23 pairs on
anterior region and 13 to 15 pairs on posterior region of dorsal shield, and 3 to 7
pairs of marginals on lateral membrane; submarginal series of setae lacking.
Male with all marginal setae of anterior and posterior regions on edge of dorsal
shield; total number of posterior (R) marginals fewer than in female. Some
dorsal setae of adults, but not r3 or Z5, usually tricarinate or vestigially so;
humeral seta r3 on dorsal shield, similar in size, shape, and orientation to neighboring
setae.
BODY VENTER. Female with third sternal pores and fourth sternal setae on
metasternal plates; genital shield truncate posteriorly, paragenital pores on membrane
beside its posterolateral corners; ventrianalshield with five to seven pairs
of ventral setae; Zvl on membrane or absent, Jv5 on ventrianal shield or on membrane;
peritrematal shield united to dorsal shield well anteriad of humeral seta,
tapered posteriorly; spermatheca with sclerotized cervix and long, fine accessory
duct. Male with sternogenital and peritrematal shields free from ventrianal shield.
GNATHOSOMA. Base of tritosternum expanded, bifid, and denticulate distally,
enclosing insertions of laciniae (Fig. 48). Tectum rounded or triramous, smooth
or denticulate. Deutosternum with rows of denticles moderately wide; width of
fourth or fifth row three to four times diameter of socket of internal rostral seta;
each row multidenticulate; sixth row slightly widened beyond lateral lines.
Corniculi of usual length, well separated, parallel. Fixed chela multidentate, its
distal extremity with enlarged, rounded anterior margin bearing curved row of
small teeth (Fig. 43); movable digit tridentate. Male spermatodactyl without
subapical pointed projection on ventral surface. Protonymph with one seta on
palptrochanter.
LEGS. Tarsus I lacking a conspicuously clavate-tipped seta dorsodistally.
Femur I typically shaped, gradually narrowing basally. Leg II of female (and
male) usually markedly thickened, with strong, opposable spinelike setae on
ventral surfaces of femur, genu, tibia, and tarsus.
Adult setation of legs I-II-III-IV
neotenous and varying interspecifically, genua from 11-11-9-9 to 8-7-6-6; tibiae
from 11-10-8-10 to 9-7-7-7.
Setae av-2 and pd-3 absent on genu and tibia I (Fig.57); some or all of following setae not expressed in some species:
- genu I: ad-3, pd -3, av-2, av-1, pv-l;
- genu II: ad-3, pd-3, al-2, pl-2, pv-l;
- genu Ill: al-2, av-1;
- genu IV: pd-3, al-2, pl-1;
- tibia I: ad-3, pd-3, ad-2, av-2;
- tibia II: ad-2, al-2, pl-2;
- tibia Ill: al-2;
- tibia IV: pd -3, al-2, pl-2.
Trochanter I with only 4 or 5 setae, av-1 absent.
