Fungiseius Moraza & Lindquist

FEMALE

Gnathosoma. Anterior margin of epistome triangular, irregularly convex or with nearly truncate median lobe, denticulate. Seta h1 about as long as h3 and distinctly longer than h2 (minute, spine-shaped) and pc; insertion of h2 slightly anterior to insertion of h3. Inner palp trochanter seta 3–6 times as long as outer seta, but not elongate. Deutosternum wide, with delimiting lateral lines (divergent toward the base) and seven (rarely eight) rows of 6–10 denticles each (lateral lines extending only from first to sixth most distal rows in F. clavulisetis Moraza & Lindquist ). Corniculi 2–3 times as long as their basal widths, well separated from each other, subparallel to slightly convergent distally. Cheliceral digits of similar lengths, stout; fixed digit with 5–11 teeth in addition to apical tooth; pilus dentilis setiform, small; movable digit with three teeth in addition to apical tooth.

Idiosoma. Elongate. Dorsum: dorsal shield distinctly smooth or ornamented, with delineated strip along lateral margins, without lateral incisions at region of fusion; anterior end of dorsal shield either strongly deflexed, concealing bases of j1 and z1 from dorsal view, or reaching anterior margin of idiosoma, with j1 inserted right at the edge of the shield and directed forward. No supernumerary setae on dorsal shield. Podonotal region of shield with 17 or 22 pairs of setae. Opisthonotal region of shield with 11 or 15 pairs of setae. Unsclerotised lateral cuticle with 5–8 pairs of setae, including r3, which is distinguished or not from neighbouring setae by being almost perpendicular to surface and/or longer than neighbouring setae. Most dorsal setae of similar lengths, much shorter than distance to subsequent setae, acicular and smooth (Z4 and Z5 distinctly longer and capitate in F. clavulisetis ). Venter: presternal region lightly sclerotised and consolidated to anterior edge of sternal shield. Sternal shield bearing three pairs of setae of similar lengths (st1–st3); st2 slightly closer to st3 than to st1; posterior shield margin with a short or distinct median lobe. Third pair of lyrifissures (iv3) and st4 inserted on metasternal plates that may be free from sternal shield or narrowly connected to it. Genital shield not wide enough to include iv5, but bearing st5; posteriorly truncate. One to three pairs of variously shaped metapodal plates. Usually with 1–2 pairs of elongate platelets between genital and anal or ventrianal shields. Opisthogaster with nine pairs of setae in addition to circumanal setae; with a small ovoid (longer axis longitudinal) anal shield or a subtrapezoidal ventrianal shield, the latter bearing three pairs of opisthogastric setae; para-anal setae inserted between levels of posterior margin and mid-length of anal opening, less than half as long as post-anal seta. Anal opening not enlarged, 1/4 to 1/5 of shield length, separated from posterior shield margin. Anterior section of endopodal shield fused with sternal shield, with a pore at apex of extension between coxae I–II; section behind sternal shield a V-shaped platelet between coxae III– IV and irregularly shaped platelet beside coxa IV. Exopodal shield distinct along coxae I–IV.

Peritreme. Extending from stigma to region between levels of s1 and z1; about as wide as diameter of stigma. Peritrematic shield wide, broadly fused with dorsal shield at level between s1 and z1 and broadly or narrowly connected to exopodal shield beside coxa IV.

Legs. Median section of pulvilli of legs II–IV rounded. Setation of legs I–IV, genu: 12 (or 13), 10, 8, 9 (or 10); tibia: 12, 10, 8, 10. Leg II much stouter than other legs. Legs with several tarsal setae thick and spine-shaped. Tarsus I with a solid, long and erect dorsobasal seta. Setae ad1 and pd1 of tarsi II–IV as long as pretarsi.

Spermathecal apparatus. Phytoseiid-type.

MALE

Epistome similar to female. Corniculi similar to female, but stouter and slightly more separated. Fixed cheliceral digit with six teeth in addition to apical tooth; movable digit with one tooth in addition to apical tooth; spermatodactyl slightly longer than movable digit, slightly undulate, finger-shaped, with a short apical process. Dorsal shield with ornamentation similar to female, but broader, including s2. Shape of dorsal setae similar to female. Presternal region as in adult female. Sternogenital shield with five pairs of setae (st1–st5) and three pairs of lyrifissures (iv1–iv3); posterior margin slightly convex. Endopodal shield fused with sternogenital shield, except for region beside coxa IV, fused with sternogenital shield only anteriorly. One or two pairs of metapodal plates. Ventrianal shield subtriangular, relatively small, leaving a wide surrounding area of unsclerotised cuticle, bearing four of the seven pairs of opisthogastric setae in addition to circumanal setae; abutting sternogenital shield. Fused peritrematic and exopodal shields extending around posterior margin of coxa IV to abut posterior end of endopodal shield. Legs as in female.
