Introduction

Deltocephalinae is comprised of over 38 tribes, 6,683 described species under 923 genera, making it the largest subfamily of Cicadellidae based on the number of described species, and is found in all geographical regions (Zahniser and Dietrich, 2013). Up to date, 31 genera and 57 species of Deltocephalinae have been recorded from Pakistan (Khatri and Webb, 2010). Subfamily Deltocephalinae includes small-to-large, mainly wedge-shaped leafhoppers. Ocelli on anterior margin of the head near to eyes; frontoclypeus not swollen, carinae absent; lateral frontal sutures reaching to ocelli; antennal ledges reduced or absent; gena with a fine erect seta laterad of lateral frontal suture, large, usually covering up the proepisternum. Forewing macropterous to brachypterous; if macropterous, with apices overlapping at rest; with 3 anteapical cells; often with 1 or more cross veins between A1 and claval suture; inner apical cell narrowed distally, not reaching to wing apex. Profemur AM1 setae distinct; row AV with short stout setae extending from base to 1/2 to 2/3 length of femur; intercalary row with various thin setae arranged in one row. Mesotrochanter with apical postero ventral stout seta. Metafemur macrosetal formula usually 2+2+1 with penultimate pair close-set. Metatibia usually anteroposteriorly compressed, ventrally with a median ridge. Male pygofer usually with a membranous cleft at basolateral margin. Valve produced posteriorly, lateral margins short, articulated with pygofer laterally. Sub genital plates articulated with each other and with valve; usually triangular, normally somewhat flattened; with dorsal slot or fold articulating with style. Connective Y-shaped or ‘linear’, rarely T-shaped; devoid of anteromedial lobe or process. Style broad at base, bilobed basally; apophysis not elongate. First valvula convex to relatively straight; dorsal sculpturing pattern reaching the dorsal margin or not; sculpturing pattern strigate, concatenate, reticulate, imbricate, maculose, or granulose. Second valvula with basal fused section as long as distal paired blades or longer; median dorsal tooth present or not; usually with small to large, regularly or irregularly shaped dorsoapical teeth on apical 1/3 or more; teeth sometimes restricted to apical 1/4, or absent.

During ongoing studies on the leafhopper fauna of Pakistan, three additional species belonging to subfamily Deltocephalinae, Changwhania terauchii Matsumura (1915) n. rec., Paralimnellus cingulatus Dlabola (1960) n. rec. and Linnavuoriella arcuata Hamilton (1980) n. rec., are reported for the first time from Pakistan. The material examined is deposited in the Entomological Museum, Northwest AandF University, Yangling, Shaanxi, China (NWAFU).

Genus changwhania kwon, 1980

  • Type species: Aconura terauchii Matsumura, 1915 by original designation.
  • Changwhania Kwon, 1980, 96, 97; Webb and Heller, 1990, 452.
  • For a detailed description of this genus, see Zhang et al. (2009).

 

Distribution

Palaearctic Region; Asia; Austro-Oriental Region

Key to species of Changwhania from Pakistan (males)

  • Coronal margin of crown with pair of round black markings; aedeagus with subapical processes and truncate apex…..C. terauchii
  • Coronal margin of crown with pair of oval black markings; aedeagus with apical processes and apically rounded…..C. ceylonensis

 

Changwhania terauchii (Matsumura, 1915) (Figure 1 A–I), new record to Pakistan

 

Materials examined: 21, Pakistan: Azad Jammu and Kashmir: Muzaffarabad, 737 m, 12-VII-2016, coll. Naveed Hassan. 411, Azad Jammu and Kashmir: Rawalakot, 1638 m, VII-2017, coll. Naveed Hassan.


Remarks: This species can be distinguished by the head having large spots and truncate aedeagal apex with subapical processes; crown with spots more rounded than usual in ceylonensis and large facial spots. Both species have similar distributions and are sympatric in Nepal and possibly in other areas as well.

Distribution: Korea, Japan, China, India, Thailand, Malaysia, Java, Pakistan

Genus Linnavuoriella Evans, 1966

Linnavuoriella Evans, 1966: 134 (Type: Platymetopius arcuata Motschulsky, 1859)

Crown margin anteriorly with transverse submarginal ventral fuscous line. Forewings with dark spot at tip of clavus, two dark spots on apical margin (Figure 2 A, B and C).

Subgenital plate elongate, broader at base, tapering apically with submarginal setae (Figure 2F). Style with sharp pointed apophysis (Figure 2E). Aedeagus with two pairs of petal-like terminal processes sub equal in length; gonopore subapical; dorsal apodeme finger-like (Figure 2 G, H).

Genus Paralimnellus Emeljanov, 1972, new record to Pakistan

 

This genus closely resembles Calamotettix Emeljanov, in the aedeagal shaft dorsoventrally flattened, style shape and pygofer lobe with processes extending from the inner wall, but can be differentiated by the subgenital plates with apex narrow, anteclypeus narrowed apically and lacking the first ante-apical cell on the elytra (Emeljanov, 1972). This genus is represented by only one species and is recorded for the first time from Pakistan.

Distribution: Palaearctic Region, Oriental Region.

  • Paralimnus cingulatus Dlabola, 1960: 2
  • Paralimnus (Bubulcus) cingulatus Dlabola, 1961: 320
  • Paralimnellus cingulatus (Dlabola), Emeljanov 1972: 107
  • Bubulcus cingulatus Dlabola; Hamilton 1975: 487; Webb and Heller 1990: 8
  • Paralimnus (Dlabolasia) cingulatus Dlabola; Nemesio 2007: 143
  • Paralimnellus cingulatus Xing and Li, 2011: 5456, new taxonomic status
  • Length (including tegmen). Male: 2.7–2.9 mm; Female: 3.5 mm.

 

Material examined: 4, 3, Pakistan: Azad Jammu and Kashmir: Rawalakot, 1638 m, VII-2017, coll. Hassan Naveed.

Distribution: USSR, Iran, Nepal, India, Korea, China, Pakistan.

Note: Emeljanov (1972) provided illustrations for the male pygofer side and aedeagus. Hamilton (1975) and Webb and Heller (1990) did not provide figures of the male genitalia.
