Description.

(Holotype larva):

Dorsum: Prodorsal scutum with two pairs of sensilla (ASE and PSE) and two pairs of setae (AL and PL). AL located slightly anterior to ASE bases, PSE present at posterior pole of scutum, Posterior pair of sensilla (PSE) more than three times longer than anterior pair ASE, both finely ciliated on their distal halves. Cuticular lines surround both sensilla. AL longer than PL, both with long dense barbs on their entire lengths. Prodorsal scutum almost pentagonal in shape, straight anteriorly, round posteriorly, widest at the level of PL setae (Fig. 3). Two pairs of eyes present at the level of posterior end of scutum dorsolaterally on idiosoma, anterior pair 24 (22-24) across, posterior pair 14 (13-14) across. Dorsal setae on idiosoma, 16 pairs (fD = 32), barbed and ranging in lengths from 29-61 (28-64)(Fig. 1).

Venter: Idiosoma ventrally bears setae 1a between coxae I, setae 3a slightly anterior to the area between coxae III; 1a 50 (48-54), 3a 28 (28-32) long; opisthogaster behind the coxae III with 10 setae (fV=10). All ventral setae with dense barbs. NDV = 32+10 = 42 (Fig. 1B). Coxae I-III each with one coxalae; all coxalae barbed. Coxalae 1b three times longer than 2b (Fig. 2).

Gnathosoma: Infracapitulum with one pair of nude hypostomal setae (Hy) 30 (30-34) and nude galealae (Ga) 23 (21-24), supracoxalae present, very small, peg-like. Palp five segmented, palpfemur and genu each with one barbed seta, palptibia with three barbed setae, tibial claw bifurcate. Palptarsus with one eupathidium, one solenidion, two smooth and four barbed setae including one long seta (Figs 4, 4a). Palp setal formula: fPp: 0-B-B-BBB2-NNBBBBζω.

Legs: Legs seven segmented with divided femora, all legs longer than body length; leg III the longest one, Tarsi terminate into two lateral claws and a claw like empodium. Chaetotaxy of leg segments: coxae 1 –1– 1; trochanters 1 –1– 1; basifemora 3 –3– 3; telofemora 5 –5– 5; genua 8+1σ+1κ - 8+1κ - 8; tibiae 14 + 2φ+ 1Cp + 1κ - 15 + 2φ - 15+1φ; tarsi 22 + 1ω + 1ε + 1Cp + 2ζ - 20+ 1ω + 1Cp + 2ζ - 20 + 1ζ (Figs 5-13).

Etymology.

The specific epithet is derived from the name of famous mountain "Uhad", where holotype larva was collected.

Type material.

Holotype larva was collected from the mountain “Uhad”, Al-Madina, Saudi Arabia, 24°30.086'N, 39°36.41'E, on 23 February, 2013, coll. M. Kamran), parasitizing tamarix leafhopper, Opseius sp. ( Hemiptera : Cicadellidae ), from Tamarix sp. ( Tamaricaceae ). Paratypes 4 larvae, collection data same as holotype, while one paratype was collected from Wadi-e-Hanifa near Arqa over bridge, Riyadh, Saudi Arabia, 24°41.354'N, 46°37.042'E, on 14 April, 2013, from Tamarix sp. in association with the same host, coll. M. Kamran. Holotype and 4 paratypes (P2, P3, P4, P5) are deposited in the King Saud University Museum of Arthropods (KSMA) and Acarology Laboratory, Department of Plant Protection, College of Food and Agriculture Sciences, King Saud University. One paratype (P1-accession no. Acy: 14/47) has been deposited at the Agriculture Research Council, Plant Protection Research Institute, Biosystematics Division, Pretoria (ARC-PPRI), South Africa.

Remarks.

Erythraeus (Erythraeus) uhadi sp. n. belongs to a group of species of subgenus Erythraeus that share the following combination of characters: basifemoral setal formula 3 –3– 3, tibia I with 14 normal setae, Ti III 270-334, Ti II 170-210, genu III 120-200.
