Checklist and keys to Deltocephalinae leafhoppers (Hemiptera, Cicadellidae) from Pakistan

Abstract

Keys to all levels of the subfamily Deltocephalinae (Hemiptera: Cicadellidae) of Pakistan are provided based on published records and original data from recent research. Checklists to the genera and species of Deltocephalinae are also given. A total of 49 genera with more than 100 species are now known from Pakistan. Two new synonyms are proposed, i.e., Cicadulinastriata Ahmed, 1986 a junior synonym of Cicadulinachinai Ghauri, 1965, syn. nov. and Macrostelesparafalcatus Naveed & Zhang, 2018 a new junior synonym of Macrostelesindrina (Pruthi, 1930), syn. nov.

Introduction

Cicadellidae, the largest family of Hemiptera, comprises 26–40 subfamilies (depending on the classification used, e.g., Dietrich 2005 and Oman et al. 1990, respectively). Included are nearly 22,000 species of which more than 200 species are known from Pakistan (Khatri and Webb 2010). The largest leafhopper subfamily, Deltocephalinae, is found in all geographical regions and comprises more than 38 tribes and 923 genera (Zahniser and Dietrich 2013). The earliest Deltocephalinae to be recorded from Pakistan were by Pruthi (1930, 1936) who recorded several species from Indian localities which are now in Pakistan, e.g., Lyallpur, Changla Gali and Murree Hills. Thirty-one genera and 57 species of the subfamily were recorded from Pakistan by Khatri and Webb (2010); these authors also provided a checklist to Pakistan Deltocephalinae and illustrated the species, some new. Subsequently, Khatri and Rustamani (2011) provided a key to tribes and genera known at that time from Pakistan and, due to the revised classification of Zahniser and Dietrich (2013), some genera have been transferred from one tribe to another (see Remarks under Deltocephalinae). In this paper we add a further 18 genera and 51 species records, provide checklists and keys to species and include two new species synonymies; a total of 49 genera with more than 100 species is now known from Pakistan.

Much taxonomic work needs to be done for the fauna of Cicadellidae in various countries and this is particularly true for Pakistan. Such studies are not only important to discover the leafhopper diversity but also for pest management in agriculture and forestry as leafhoppers being one of the most important groups of vectors of plant pathogens (Claridge and Wilson 1991; Wilson and Turner 2010).

Materials and methods

All specimens were examined with a Leica ZOOM2000 stereomicroscope. Drawings were made using an Olympus drawing tube. Photos were taken by a ZEISS SteREO Discovery.V20 stereomicroscope equipped with a ZEISS AxiocamICc 5 camera that also provided measurements. Adobe Photoshop CS was used to compile photographs. Specimens from Pakistan are deposited in the various collections as indicated in the published records and additional specimens, examined and figured for this study, are deposited in the Entomological Museum, Northwest A&F University, Yangling, Shaanxi, China.

Taxonomy

Deltocephalinae Fieber

The subfamily Deltocephalinae includes small-to-large, mainly wedge-shaped leafhoppers diagnosed as follows: head with ocelli on anterior margin near to eyes; frontoclypeus not swollen, carinae on anterior margin of head usually absent; lateral frontal sutures reaching to ocelli; antennal ledges reduced or absent; gena large, usually covering proepisternum, with a fine erect seta laterad of lateral frontal suture. Forewing macropterous to brachypterous; if macropterous, with apices usually overlapping at rest (except Gurawa); with two or three anteapical cells and often with one or more crossveins between A1 and claval suture; inner apical cell narrowed distally, not reaching to wing apex. Profemur AM1 seta distinct; row AV with short stout setae extending from base to 1/2–2/3 length of femur; intercalary row with various thin setae arranged in one row. Mesotrochanter with apical posteroventral 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. Subgenital plates articulated with each other and with valve rarely fused to each other and valve (Goniagnathus); 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 striate, concatenate, reticulate, imbricate, maculate, 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.

Remarks. We treat Deltocephalinae here in its wider sense, following Zahniser and Dietrich (2013) to include Selenocephalini, Mukariini and Penthimiini. We also follow Zahniser and Dietrich (2013) for the placement of genera in tribes; this has particular implications for Bampurius placed in Athysanini by Khatri and Webb (2010), here placed in Scaphoideini and the genera placed in Scaphytopiini by Khatri and Webb (2010), i.e., Grammacephalus placed here in Scaphoideini, Masiripius placed here in Opsiini and Varta placed here in Vartiini.

Checklists and keys to species of Pakistani Deltocephalinae

Keys to all species of Pakistan Deltocephalinae are given for each genus containing more than one species. We follow Zahniser and Dietrich (2013) for most of the tribal diagnostic characters.

Athysanini Van Duzee

Diagnosis. It is impossible to provide a set of characters to easily diagnose this large tribe due to its morphological diversity. However, most members have the connective Y-shaped and lack the distinctive features of other tribes.

Euscelidius Ribaut

E.cornix Naveed & Zhang

Figs 23, 36, 52

Euscelidiuscornix Naveed & Zhang, 2020c: 470, fig. 1A–G (Pakistan).

Platymetopius Burmeister

Platymetopius sp.

Remarks. From the figure (code number DW 50A, unidentified) given by Mahmood (1969) this genus is present in Pakistan.

Tambocerus Zhang & Webb

Remarks.Tambocerus is one of the few Athysanini with transverse striations on the fore margin of the head.

T.bulbulus Naveed & Zhang

Figs 22, 39, 51

Tambocerusbulbulus Naveed & Zhang, 2018i: 240, figs 3A–D, 4A–I (Pakistan).

Chiasmini Distant

Diagnosis. These are small to medium sized leafhoppers, usually white, stramineous, green, brown, grey, or black in colouration, and sometimes iridescent. They can be identified by the tapering or parallel sided clypellus, aedeagus hinged at the base (hinge usually but not always present), ovipositor usually extending far beyond the pygofer, first valvula dorsal sculpturing pattern maculate to granulose and usually submarginal, first valvula without distinctly delimited ventroapical sculpturing, and second valvula teeth obliquely triangular and serrated.

Cicadulini Van Duzee

Diagnosis.Cicadulini, following Zahniser and Dietrich (2013: 56), is a rather poorly defined tribe. It was defined by these authors in the following way: “small to medium sized, slender, stramineous, yellow, or greenish leafhoppers, sometimes with the anterior margin of the head marked with black spots. They can be identified by the male segment X often long and strongly sclerotised, and subgenital plates sometimes with a row of macrosetae near the middle and with long fine setae laterally” and additionally in their key: “male pygofer incised dorsally nearly to base”. Clearly, this definition is not ideal as you may not be able to identify a taxon (for example in a key) based solely on “often” and “sometimes” characters and also in their figure 15 of Cicadula Zetterstedt, segment X is moderately long (although the dorsal pygofer incision is very long and therefore the dorsal bridge very short). In addition, the genus Pseudosubhimalus Ghauri, placed in Athysanini by Zahniser and Dietrich (2014), was subsequently placed in Cicadulini based on molecular evidence and (in its type species) segment X is long and well sclerotised (Meshram and Niranjana 2019) However, in the genus the subgenital plate macrosetae are marginal, and in one of its species, P.katraini Meshram and Niranjana, segment X is very short. Similarly, segment X is not elongate in the Nearctic Knullana DeLong. The following three species of this genus occur in Pakistan.

Remarks. A re-examination of the material identified and figured as M.indrina by Khatri and Webb (2010) and original figures of M.parafalcatus shows that there is insufficient evidence to separate the two species. The two species differ only very slightly in the separation of the long apodemes of the second abdominal sternite (fig. 64). Other differences seen in their respective original figures, i.e., of the aedeagus and style, are due to differences of orientation. Therefore, we consider the two species to be synonyms.

Paralimnini Distant

Diagnosis. These are small to medium sized leafhoppers. They can be identified by the combination of the following characters: clypellus tapering apically or parallel-sided, lorum narrower than clypellus at base; connective with anterior arms closely appressed, articulated with aedeagus; female first valvula sculpturing imbricate or rarely maculate or granulose. The tribe is very similar morphologically to the closely related Deltocephalini, from which it can be distinguished by the articulation between the connective and aedeagus (fused in Deltocephalini), although a few species of Flexamia (Paralimnini) have the connective fused to the aedeagus.

Remarks.Khatri and Rustamani (2011) pointed out that the paralimnine HengchuniapakistanicaAsche and Webb (1994) was erroneously recorded from Pakistan as it is known from the Indian state of Gujarat (spelt as Gudjarat).

Scaphoideini Oman

Diagnosis.Scaphoideini, following Zhaniser and Dietrich (2013: 148), is a rather poorly defined tribe. It was defined by these authors in the following way (with wording from their key to tribes in square brackets and added characters from Viraktamath and Yeshwanth (2020) in bold): “None of the following characters are present in all taxa, but some combination of [most of] these characters is present in all and a few (*) appear to be unique to this tribe: head narrower than pronotum, produced; genae sometimes wide and visible dorsally; frontoclypeus long and narrow; antennae long [longer than width of head]; body slender; head and wings often with brown, orange, ochraceous, or ivory markings; forewing with one or more darkly pigmented reflexed veins in vicinity of outer anteapical cell; profemur row AV setae absent or reduced (without stout setae); metatibia macrosetae in row PD long, as long as or longer than 0.5x length of protibia*; male or female pygofer with dense tufts of long fine or regular [macro] setae*; subgenital plate apex membranous or long, digitate, and somewhat membranous or weakly sclerotised; subgenital plates with long fine setae laterally and/or dorsally (also occurs in other deltocephaline tribes); basal processes of aedeagus or connective sometimes present, connected or articulated to base of aedeagus or apex of connective stem; aedeagus sometimes fused to connective”. The last mentioned character is found in Sikhamani Viraktamath and Webb and Thryaksha Viraktamath and Murthy.
