Agallia Curtis

Agallia Curtis 1883: 193 . Type species: Agallia consobrina Curtis , by monotypy.

Anaceratagallia Zachvatkin 1946: 159 , 160. Type species: Cicada venosa de Fourcroy ( France).

Description. Brown, with two spots on crown, one median spindle shaped spot and two large, rather triangular spots on posterior half of pronotum and spot on either side of median line on anterior half of pronotum, brown to dark brown. Scutellum with basal triangles dark brown to black. Forewing venation dark brown. Vertex medially longer than next to eyes, hind margin evenly rounded. Ocelli rather high on face, about as far apart from each other as from adjacent eye. Pronotum transversely rugose and punctuate, longer than median length of vertex and scutellum. Forewing with three subapical cells, inner subapical cell closed basally by crossvein. Male pygofer with caudal margin prolonged into spinelike process ventrally ( Figs 4 c, 5c, 6c,d). Anal collar process well developed. Subgenital plates boat-shaped, with stout setae. Style inner fork longer than outer fork. Connective broader than long. Aedeagus simple, with well developed dorsal apodeme, with or without small processes, gonopore subapical.

Remarks. Species of this genus were collected from the study area and two are new records for Pakistan. All three species have similar color pattern which may vary in tonality.

Agallia robusta Pruthi (Plate 1d, Fig. 4 ).

Measurements (mm). Male total length 3.63, forewing length 2.97, crown length at middle 0.18, crown width across eyes 1.27, pronotum width 1.12, pronotum length 0.58, mesonotum length 0.15, scutellum length 0.31.

Material examined. Pakistan: Sindh Prov., 4 3, 37 Ƥ, Tandojam, 6.iv.08, I. Khatri, at light (IKC).

Distribution. India, Pakistan.

Remarks. This species is similar to A. aciculata and A. cuspidata in general appearance but differs in the shape of the acute process of the pygofer posterior margin, the shape of the male anal collar and the aedeagal shaft lacking the processes found in the other two species. Originally recorded by Pruthi (1930) before the creation of Pakistan.

Agallia cuspidata (Dlabola) (Plate 1e, Fig. 5 ) New record.

Measurements (mm). Male total length 4.0, forewing length 3.22, crown length at middle 0.22, crown width across eyes 1.41, pronotum width 1.33, pronotum length 0.59, mesonotum length 0.27, scutellum length 0.33.

Material examined. Pakistan: Sindh Prov., 5 3, 40 Ƥ, Tharparkar, 12.xi.07, I. Khatri and 1 3, 4 Ƥ, with same data but collected on 18.v.06 (IKC).

Distribution. Afghanistan, Pakistan.

Remarks. This species resembles A. aciculata and A. robusta in general appearance but differs in the male anal collar process being tridentate ( Fig 5 c) and the very conspicuous aedeagal shaft with medial and apical processes.

Agallia aciculata Horváth (Plate 1f, Fig. 6 ) New record.

Measurements (mm). Male total length 3.18, forewing length 2.54, crown length at middle 0.15, crown width across eyes 1.17, pronotum width 1.07, pronotum length 0.49, mesonotum length 0.13, scutellum length 0.25.

Material examined. Pakistan: Sindh Prov., 2 3, 4 Ƥ, Tharparkar, 6.vii.07, I. Khatri (IKC).

Distribution. Asia, Europe.

Remarks. This species resembles A. robusta and A. cuspidata in general appearance but differs in the shape of the male anal collar process ( Fig 6 c) and the aedeagal shaft in bearing a subapical denticle.
