A review of Gryllidae (Grylloidea) with the description of one new species and four new distribution records from the Sindh Province, Pakistan.

Seventeen species of the family Gryllidae were reviewed and a Modicogryllussindhensis is described herein as new. Four species, namely Achetahispanicus Rambur, 1838, Gryllusseptentrionalis F. Walker, 1869, Callogryllussaeedi Saeed, 2000, and Miogryllusitaquiensis Orsini & Zefa, 2017 are recorded as new country and state records. Differences between similar species and a taxonomic key to the species of Sindh are provided. Riffat Sultana, Surriya Sanam, Santosh Kumar, Sheik Mohammad Shamsudeen R, Fakhra Soomro.

Introduction

Crickets are representative of superfamily with six (four families: , , and ) Gorochov, 1985, Laicharting, 1781, Costa, 1855, Blanchard, 1845, Zeuner, 1937 and Saussure, 1874 (Cigliano 2021). The group dates back from the Triassic Period and today includes 3,700 for all species of orthopterans known living and 43 extinct species, 22 extant and 27 extinct subfamilies, and 528 extant and 27 extinct genera (Resh and Carde 2009). The Species File is a taxonomic database of the world’s including grasshoppers, katydids, crickets, and related insects, both living and fossil. It has full taxonomic and synonymic information for more than 29,060 valid species and includes 47,500 scientific names and 106,200 specimen records.

Crickets live in virtually all terrestrial habitats from treetops to a meter or more beneath the ground. Field crickets live in oligotrophic, dry, barren habitats. Crickets are abundantly found at night but conceal themselves in thick vegetation, leaf litter, and under stones and rocks. Crickets are drab, or brightly and intensely coloured. Crickets have an incomplete metamorphosis with three life stages viz., egg, nymph, and adults. Females insert their eggs in soil and lay their egg on plants (Alexander 1962).

The classification of the has been established by Henri de Saussure in a remarkable monograph published in Geneva in the years 1877 and 1878. In this thorough work, the author points out the most important morphological characters and establishes the larger divisions of the group. Although a great number of species have been described since the publication of Saussure’s work, it remains the basis of the modern classification of the . The are abundant throughout Sindh, the most cultivated region of Pakistan that are damaged by mole crickets, ground crickets, field crickets, house crickets, etc. The live in different types of habitats such as moist soil, herbs, shrubs, grasses, and vegetation. The fauna of from Sindh is insufficiently known. It was therefore felt necessary to revise the family from this region. Descriptions, taxonomic keys, and illustrations for all 17 known species are provided; bionomics and ecological accounts are also briefly discussed. In this manuscript we offer one new species and four new records from Pakistan, which aid in filling the gaps in our knowledge of the of Pakistan and bring information up to date.

Materials and methods

All specimens were collected from different agricultural crops in various districts of Sindh. Material was brought to Entomology and Bio-control Research Laboratory (), Department of Zoology, University of Sindh, Jamshoro. Methodology for euthanasia was adapted from Vickery and Kevan (1983) and Riffat and Wagan (2015) with slight modifications: specimens were killed by using potassium cyanide or chloroform in standard entomological killing bottles for 5–10 minutes. Samples were not left longer because their colours could change.

Pinning of samples was done quickly after killing. An insect pin was inserted on the pronotum posterior to transverse sulcus, slightly to the right of the median carina. The head was directed slightly downwards on the stretching board. The left wings were set with the long axis of the body nearly at a right angle to the pin. The posterior legs were bent beneath the body to minimize the possibility of breakage and to occupy a smaller area. The abdomen was dropped below the wings and not obscured by the hind legs.

Fully dried specimens were preserved in insect cabinets with labels providing collection date, habitat, locality, and collector’s name. Naphthalene balls (C10H8) were placed in boxes to prevent the attack of ants and other insects. Specimens were identified through the bibliographies given by Riffat and Wagan (2015), and Species File () (Cigliano et al. 2020) was consulted.

Photographs of the various species were prepared. Line drawings were made with a camera lucida fitted on a microscope (Ernst Leitz Wetzlar Germany 545187) and these were improved with the help of the softwares Adobe illustrator CC-2015 and Adobe Photoshop CS.

Measurements of various body parts were calculated in millimetres (mm) using the microscope (Oculas), 10 × 10 graph, compass, divider, and ruler. Abbreviations used in the text are as follows.

Ecology.

is broadly distributed in the field. They complete their life cycle within 60–70 days. Agricultural crops affected by this species are (wheat), (rice), (sugarcane), and (common lawn grasses).

Global distribution.

Czech Republic, Greece, Peloponnese, Patras, Yugoslavia, Serbia, USA, India, Pakistan (Cigliano et al. 2020).

Remarks.

is generally recognised as the house cricket, cosmopolitan in nature. The presence of this species was reported by Chopard (1969) from Himalayas, Srinagar, and Kashmir, at 6000 ft a.s.l. Previously, Ghouri (1961) stated that and other species were severe pests of many crops in Pakistan, and Malik (2012) also stated it from human habitation. At present we have recorded this species from Chachro (). We have collected large numbers of specimens from agricultural fields and confirm that it is a pest of various crops.

Denmark, Germany, Netherlands, Switzerland, UK, Pakistan (Cigliano et al. 2020).

Due to its rare status and sporadic nature is included in the red lists Hochkirch et al. (2007). It is flightless in its habitat of dune, short grasses, chalky soil, and light sandy porous soils. During our field survey we collected material from different districts. Our examination demonstrates that this species has morphological similarity to but few differences in wing pattern and head morphology identifies each species.

Argentina, Paraguay, Caribbean, Jamaica, Pakistan (Cigliano et al. 2020).

This is the first record from the deserts of Thar, Sindh, Pakistan. According to Saeed (2000), this species of cricket occurs in terrestrial habitats throughout the world, and mostly damages cotton, rice, millet, and sugarcane crops. Due to their predatory nature, they are also helpful in biological control, but more detailed investigations are needed to identify this strategy in future.

is cosmopolitan in nature. This species is generally known as the tropical house cricket or Indian house cricket because they are found everywhere, domestic in all tropical countries. Khan (1954) reported that it caused huge damage to textiles mills in India. During our field survey we observed that this species moves at dusk from the holes of a termite mound. However, this species is not termitophilous in nature like other insects; it does not live with the termites.

Annandale (1924) reported that this species lives in crevices, mostly occurring in wood and frequently in holes of bungalows. During the present study, we collected this species from a stack of wood from Umerkot.

Khan (1954) noticed that all females of deposit more than 150 eggs when temperatures are favourable, between 20–25 °C with the relative humidity of 80–82%. At present, only females were captured and is longer in total body length (20 mm) with the ovipositor ca. 15 mm compared to Chopards’ (1969) report of total body length 12–15 mm and ovipositor 12–12.5 mm. This may be a geographical variant of the region; however, a detailed and comprehensive analysis of the taxa will be undertaken when more material will be collected.

Earlier, this species was collected by Chopard (1969) from various localities of India, but his specimens were smaller in size. The elytra of this species are longer than those of , leading to the question of whether this species could be a macropterous form of the proceeding one. Considering the extreme reduction of the elytra of the female of , it seems difficult to admit the possibility of a return to fully winged form. However, future studies with more samples should resolve this problem.

is commonly known as black field cricket. Species of this genus are reported as a serious pasture pest in Australia and the warmer northern regions of New Zealand (Banfield and Cottier 1948; Reynolds and Langton 1973; Mill 1978). They reported that each year black field crickets cause considerable losses in pasture production over the dry summer period when stock feed is short. The resulting bare areas in the pasture are then opened to weed invasion because the black field crickets consume only pasture seed.

During the present study we captured only a single female from grasses, which is considered as perennial ryegrass pasture, the main feed for dairy cows in temperate regions. This study suggests that preference of crickets for perennial ryegrass may lead high risk of damage to cultivated areas of Pakistan.

Until now 52 species of were recorded by Cigliano et al. (2020). Gorochov (1985) reviewed the species from Asia and established two subgenera. He moved (Serville, 1838), (Ohmachi & Matsuura, 1951 (Saussure, 1877), (Walker, 1869), and (Le Guillou, 1841) into the subgenus with as the type species, and he moved and into the subgenus with the first as type species. Gorochov (1988) established another subgenus, , with as its type species from Africa, and added a further two new species in 1990. Otte (2006) downgraded genus as a subgenus under . The remaining species are still in the pool of the subgenus without having been studied again. In China, these crickets are often confused, and different species names have been used, until Ma et al. (2015) distinguished them by their genitalia. However, these changes are mainly based on morphological studies without molecular evidence.

This species is commonly known as black field cricket. Its powerful legs are used for jumping. This species has numerous white strips on the abdomen which make it different from the other species. Zalitschek et al. (2012) reported that they are omnivores in nature. However, dietary requirements are similar but perform different functions depending upon the sex of the specimen: females take a protein-rich diet for the production of eggs while, male requires it for producing mating calls to attract females.

Chopard (1969) compiled a detailed account on this species: the head had the same pattern as . The abdomen showed the longitudinal bands on both sides. The elytral length extended from the apex of the abdominal tergite. He calculated body length as 12 mm, pronotum 2.5 mm, elytra 2 mm, and ovipositor 9 mm. The collected specimens show variation in size as well as in other parameters, possibly due to geographical and feeding habitats. This species has unique characteristics, including the presence of a black band that runs from the pronotum where it makes a raised bulging cup-like structure; this black band covers the whole length of tegmen it follows a narrow straight line on the abdominal segments to the end of the last segment.
