  • 4Grasshoppers and locusts are ancient enemies to agriculturethey pose constant threat to value crops due to this, a numberof areas have suffered from deprivation; entire regions havehad to be discarded (Appert & Deuse, 1982).Because of thisdestructive behavior long ago attracted man’s attention.Amongst the grasshopper fauna Pamphagidae is worth ofimportant containing 93 genera and nearly 600 species orsubspecies in the world which mainly distribute inmountainous or semi-desert area in Africa, Europe and Asia.NEW RECORD OF GENUS EREMOPEZA
  • 5According to Uvarov (1943) this subfamily is divided into 9tribes most of them peculiar to southern Africa, in thePalearctic region it is represented by only 3 tribes of whichonly the Thrinchini which are characteristic principally forsemi-deserts and deserts, including the outskirts ofmountainous regions and the Pamphagini, distributed incountries along the shores of Mediterranean sea.Continue…..NEW RECORD OF GENUS EREMOPEZA
  • 6The genus Eremopeza consists of the seven species peculiar toIran and adjacent countries; these are divided into a numbersof species and subspecies. However, the systematic position ofthis genus was not studied satisfactory yet. Its division intospecies and subspecies may be modified after the extensivesurvey and detailed studies.Continue…..NEW RECORD OF GENUS EREMOPEZA
  • 7Eremopeza gigas was described by Kirby (1914) fromBalochistan. Presently a single specimen which is very closelyrelated to Eremopeza gigas has been collected from JamshoroSindh province. Further, a detail morphological description ofthis specimen has been studied and compared with alreadydescribed species. The following differences has been noted.Continue…..NEW RECORD OF GENUS EREMOPEZA
  • 8Grooves of pronotum well-marked and found distinct anduniform in depth and metazoan with pronotum tubarclus whilein E.gigas grooves on pronotum strong and median carina ofmetazoan without the tubrculate and color darker as comparedto Sindh specimen.E.gigas is less robust and pronotum and metazoan foundsomewhat narrow and longer as compared to Sindh specimen.Similarly, in E.gigas wings near the base from bluish to lightgreenish-blue in color on contrasting to this, color of wingswas light green at base in present studies specimen.NEW RECORD OF GENUS EREMOPEZA

  • 11Body very large, slender, stout and rugose, Antennae filiformabout 26 segments, slightly longer than the head and pronotumtogether. Eyes rounded prominent. Prosternum either with theanterior margin raised like a plate or with a process or conicaltubercle, or only slightly convex in the anterior part, transversegroove of mesosternum in the middle often extends caudadbetween the aleral lobes.DIAGNOSISNEW RECORD OF GENUS EREMOPEZA
  • 12Pronotum slight lyraised in front, but hardly ridged, veryslightly carinated in the middle. Tip of abdomen ventrallyreddish or reddish-rusty. All 3 transverse grooves of pronotumwell-marked, distinct, but approximately uniform in depth. Thedark band of wings is sharply right-angled with a well markedposter-external angle, apex of wing also dark. Pronotum with anarrow linear carina. Hind tibia blue with organ-red distal end.DESCRIPTIONNEW RECORD OF GENUS EREMOPEZA
  • 13Generally light yellowish in color. Antennae dark brownishwith white spots near base. Fastigium of vertex with smallerblack spots . Inner side of hind tibia blue, red apically, whileouter side dirty whitish. 8 spines inner side and 9 outer sides.Black tipped color varying with the corresponding side. Colorof wings light green at base metazoan with pronotum tubarclusand also along the side of median carina. Tegminasemitransparent with two smoky dark bands, apex having lightbrown speckles. Wings hyaline and transparent, light greenishat base.COLORATIONNEW RECORD OF GENUS EREMOPEZA
  • 14Wings near the base from bluish to light greenish blue in color.Tegmina and hind wings equal in size reaching to the end of(4th quarter) of hind tibia . Hind femur internally black exceptfor a pale pre-apical band. Hind tibia dirty whitish with thebase; a pre-median and pre-apical ring. Hind femora stronglyserrated and granulated; hind tibiae short; arolia very small.Continue…..NEW RECORD OF GENUS EREMOPEZA

  • 18It is interesting to point out that all the species ofPamphagidae were collected at higher altitudes ranging from1500 to 2500 M above sea level but, I have recorded this fromthe very low altitude for the first time. It is also evident fromthe available literature (Bei-Bienko & Mischenko (1963,1964), Junjua (1959), Uvarov (1943) and Ahmed et al (1979)that these species are restricted to higher altitude of theprovince and may be considered endemic. These observationstend to stress the need for additional surveys of endemicspecies in all the district of Sindh including other areas ofPakistan.NEW RECORD OF GENUS EREMOPEZA

  • 20As this speeies is very close to Eremopeza gigas (Kirby) andhas been compare with the specimen from Balochistan anddifference has been noted in the shape of pronotum. Shouldthis character prove to be distinct for the Sindh population, itwould justify recognition of this phenon as distinct subspecies(or species), but it is premature to make a decision, based onsingle specimen.NEW RECORD OF GENUS EREMOPEZA
