description
Description: Male. Body size: 0.7 - 0.8 mm. Head: Postfrons asetose. Eye bridge 2 - 3 ommatidia long. Postocular bristles in 1 row. Neck of fourth antennal flagellomere longer than node (Fig. 5 A). Node subglobular, with short subbasal setae, 1 mesal single to double whorl of long setae, 1 distal whorl of long, thin hair-shaped sensilla, and 2 - 3 thick hair-shaped sensilla. Maxillary palpus 3 - 4 - segmented, first and second segments with hair-shaped translucent sensilla. Wing: AntC extending beyond R 5 for 1 - 2 times the vein width. ApicR 1 = 2 - 3 times the length of Rs. Legs: Pretarsal claws without teeth. Terminalia: Sclerotization of tg 9 widely interrupted mesally. Ventral emargination of gonocoxites broadly V-shaped, not extending to midlength (Fig. 5 B). Gonostylus elongate, straight, excavated subbasomesally, with short, nose-shaped subapical process (Fig. 5 B). Tegmen long, protruding beyond apical and basal margins of gonocoxites, slightly constricted at midlength and broadened on distal half, rounded apically, with distinct dark longitudinal stripe; basal margin of ventral plate distinct, situated below midlength of tegmen (Fig. 5 C). Cerci very weak. St 10 apparently absent. Female and preimaginal stages: Unknown.
diagnosis
Diagnosis: Peromyia bashfordibashfordi is a typical representative of the Peromyia intermediaintermedia group as defined by JASCHHOF (1998) and reviewed subsequently (JASCHHOF 2001 b, JASCHHOF & JASCHHOF 2004, 2009). It is most similar to Peromyia obunca JASCHHOF, 2004 from New Zealand, from which it differs in the straight gonostyli with small subapical process. The gonostyli in P. obunca are slightly curved and lack the process. Further, the gonocoxites in P. bashfordibashfordi lack the large asetose basal portion that is present in P. obunca.
discussion
Remark on relationships: Male morphology suggests P. bashfordibashfordi and P. obuncaobunca are very closely related to one another, presumably sister species. So no doubt persists any longer that P. obuncaobunca is a member of the intermediadia group to which it was tentatively assigned by JASCHHOF & ZASCHHOF (2004).
etymology
Etymology: This species is named to honour Richard BASHFORD, Senior Silvicultural Technician at Forestry Tasmania, Hobart, who is in charge of the invertebrate collections at Warra LTER site. Types:
