| abstract | The present paper describes three new species and two new records of trombiculid mites of bats from Guangxi, China.
Trisetica asiaticus, sp. nov. (figs. 1-5)
Diagnosis of larva: This new species is closely related to T. melvivi Traub & Evans, 1950, but differs from it in the following characteristics: (1) Galeal setae branched, (2) sternal setae 2-2, (3) Leg I with 3 genualae, (4) Body with 59 ventral setae, (5) SD 36.7µ, SB 14µ (6) Palpal setation formula: B/B/NNB.
Diplectria sinensis, sp. nov. (figs. 6-10)
Diagnosis of larva: This new species is close to. D. calva Domrow, 1962, but isreadily separable by the following characteristies: (1) Body with 65 dorsal setae and 57-59 ventral setae, (2) Scutum larger, (3) Palpal setation formula: B/B/BNB.
Microtrombicula (Microtrombicula) guangxiensis, sp. nov. (figs. 11-17)
Diagnosis of larva: This species close to M. (M) hexasternalis V.-G., 1965. It is readily separable as follows: (1) Scutum roughly trapezoidal, (2) Body with 33 dorsal setae and 31 ventral setae, (3) Formula of coxal setae B3-4,B0-1, B3-4; Formula of sternal setae: 2B2, 2B3, 2N, (4) Leg I with 2 genualae and leg III with 3 mastitarsalae, 2 tibialae, (5) Palpal setation formula: B/B/NNN.
Holotype specimens of the above three new species are deposited in the Sanitation and Anti-Epidemic Station of Guangdong, the paratype of Diplectria sinensis sp. nov. is deposited in the Department of Parasitology, Chongqing Medical College. |
