Acrotrichis britteni Johnson, 1969

Fig. 17A

Diagnosis

The form of the spermatheca distinguishes this species ( Fig. 17A ).

Material examined

MALAYSIA-BORNEO • 1 ♀, Sarawak; May–Aug. 1978; P.M. Hammond and J.E. Marshall leg., BMNH 1978-49 ; Marndi grass heaps; BMNH • 1 ♀, Sarawak, 4 th Division, Gunung Mulu National Park ; May–Aug. 1978; P.M. Hammond and J.E. Marshall leg., BMNH 1978–49 ; under buffalo dung; BMNH .

Remarks

Tropical, mainly synanthropic species recorded from various parts of tropical Asia. Johnson (1985) noted that he had seen only females from the Seychelles and Mascarenes and considered that the species was parthenogenetic; he added the rider, however, that he had also seen possible males from West Bengal. More recently, he determined males taken by myself in Kerala, S. India, in association with females as possibly britteni (unpublished).
