Hydaticus
Leach, 1817 is a large genus of dytiscid
beetles. This genus has an almost worldwide distribution,
with most of the about 150 species inhabiting the Old
World tropics (Nilsson, 1995). So far, 3 species have been
recorded from Pakistan:
Hydaticus histrio
Clark, 1864,
Hydaticus ponticus
Sharp, 1882, and
Hydaticus ricinus
Wewalka, 1979 (Franciscolo, 1968; Wewalka, 1979;
Nilson, 2003). This genus inhabits pools, puddles, margins
of lakes, riverine forest pools, and intermittent stream
pools. They can also be caught in paddy fields. Ecology
varies greatly from species to species, with the rare ones
being confined to forest habitats (Hendrich et al., 2004).
The specimens were collected by Z. Ahmed from
Mirpur Khas, Sind of Pakistan on June 27, 2007.

Aquatic Coleoptera from Pakistan: faunistic and zoogeographical contribution (Coleoptera: Gyrinidae: Dytiscidae: Hydrophilidae)

Records of 19 species and one subspecies of water beetles of four families: Gyrinidae (two species), Dytiscidae (seven species), Hydrophilidae (10 species), and Spercheidae (one subspecies) from Pakistan are listed, based on collected material. Four genera and 10 species are recorded from Pakistan for the first time. The newly recorded genera are: Patrus, Helochares, Sternolophus and Coelostoma. The newly recorded species are: Dineutus spinosus (Fabricius, 1781), Patrus haemorrhous (Régimbart, 1891), Copelatus freudei Guignot, 1955, Copelatus sp1, Copelatus sp2, Enochrus ater (Kuwert, 1888), Helochares anchoralis Sharp, 1890, Sternolophus rufipes (Fabricius, 1792), Paracymus aeneus (Germar, 1824) and Coelostoma stultum (Walker, 1858). Zoogeographic affinities of the recorded species are discussed. According to their current distribution, the 18 species known from Pakistan can be classified into five zoogeographical categories.

  • Dec 2018
The present study was carried out to investigate the biodiversity, abundance and seasonal fluctuation of ground beetles on Massa region from June 2015 to October 2016. The beetles were collected using 20 pitfall traps which were operated on a weekly basis, a total of 2867 specimen representing two families Carabidiae and Tenbrionidae and 10 genera (Blaps polychresta, Zophosis punctata, Pimelia interpunctata, Blaps nitens, Adesmia dilatata, Scaurus vicinus, Tentyria cyrenaica, Laemostenus complanatus, Ditomus cilpeatun and Akis costitubera were recorded. Overall diversity was 81% and 83% Simpson's scale and Shan-non's scale respectively. The highest index; 0.116841 (Simpson's index) and 0.36693 (Shan-non's index) was found in species Z. punctata. Results showed the influence of temperature on A. costitubera, B. polychresta and D. cilpeatun with the A. costitubera being a better predictor, addition to constant of A. costitubera Beta =0.818 ; constant of A. costitubera and B. polychresta Beta = 0.625 and 0.53 and constant of A. costitubera , B. polychresta and D. cilpeatun Beta = 0.629 , 0.335 and 0.191. The results concluded the importance of using ecological indexes in studying the abundance and seasonality of ground beetles fluctuated during different seasons.

Aquatic Coleoptera of Singapore: Species richness, ecology and conservation
Article
  • Jun 2004
  • RAFFLES B ZOOL
The present paper is the first comprehensive review of the aquatic Coleoptera, or water beetles, of Singapore. A total of 93 species are reported here. They are: Noteridae (9), Gyrinidae (9), Dytiscidae (35), Spercheidae (1 ), Hydrophilidae (30), Hydraenidae (3), Limnichidae (3), Curculionidae (2), and Chrysomelidae (1). The water beetle fauna of Singapore is mainly Oriental with a high percentage of Sundaic faunal elements. Thirty species (32%) are first recorded for Singapore. However, eight species are believed to be locally extinct, and 27 species (29%) are listed as threatened. The main causes of species becoming endangered are deforestation and change of ground water level in the vicinity of springs; as well as waste water pollution and infill. The water beetle communities of the main habitat types are briefly outlined. For each species all literature references are cited, and the distribution and ecology are described. A brief account on the conservation status and future prospects of Singapore's aquatic beetle fauna is given. The dytiscid species Copelatus andamanicus Régimbart, 1899, is here suggested to be a junior subjective synonym of C. oblitus Sharp, 1882.

On a new species of Hydaticus subgen. Guignotites Brinck 1943 from Portugal, with notes on palaearctic species
Article
  • Dec 1967
Observations are given on fourteen species of Guignotites, one of which, from southern Portugal, is described as new to science. Keys at present available, being mainly based upon uncertain colour patterns, were not sufficient for the identification of the new species and so a key to males of palaearctic species, and another specifically for the separation of the new species from its allied ethiopian species, are provided. The position of H. (G.) thermonectoides Sharp is also discussed. General consideration on distribution of species having males provided or not with spined rows on the anterior tarsal plates are suggested.
