Oestropsyche vitrina Hagen, 1859  

( Figs. 177–182 View Figs )

Macronema vitrinum Hagen, 1859: 209   [Holotype male; Sri Lanka;

MCZ ( Ross, 1952: 35)]. Polymorphanisus vitrinus (Hagen) Hagen, 1864: 875   . Oestropsyche palingenia Brauer, 1868: 266   [Lectotype male;

Philippines; IRSNB; synonymised by Ulmer, 1907: 29]. Oestropsyche vitrina (Hagen) Ulmer, 1907: 29   . Oestropsyche hageni Banks, 1939: 56   [Holotype male; India; MCZ;

synonymised by Barnard, 1980: 66].

Diagnosis. Male. Antennae 30 mm in length, light brown with dark brown striations. Forewing 17 mm and hind wing 8 mm. Mesoscutum and mesoscutellum without evident markings. Tibial spurs 1.3.2.

Male genitalia. Inferior appendages two-segmented and apex forming somewhat lobular structure, potentially mistaken as separate segment. Phallus in lateral view with same orientation as that of A. sexpunctata   ( Fig. 180 View Figs ). Lateral tubercles in segment X well-developed.

Female. Antennae 13 mm in length, light brown with dark brown striations. Forewing 20 mm and hind wing 12 mm. Mesoscutum and mesoscutellum without evident markings. Tibial spurs 1.2.2.

Uy et al.: Southeast Asian Macronematinae  

Material examined. Philippines: 1 male, 5 females, Nueva Vizcaya, Imugan, coll. C.J. Uy, 13 January 2014 ( UPLBMNH)   ; 1 male, Nueva Ecija, Pantabangan, coll. C.J. Uy, 1 May 2013 ( UPLBMNH)   .

Distribution. India, Iria Jaya, Laos, Malaysia (Perak), Philippines (Luzon), Sri Lanka, Sumatra, Thailand, Java, Borneo, Bali, Sulawesi.

Remarks. Based on original description by Hagen (1859), the inferior appendages were not stated whether it is segmented or not. Barnard (1980) provided a detailed description of this species during his revision study however, illustrated that inferior appendages are unsegmented. The samples that we examined showed that inferior appendages of O. vitrina   are two-segmented ( Fig. 178 View Figs ). The male wings ( Fig. 177 View Figs ) and male genitalia ( Figs. 178–181 View Figs ) were redrawn. Head in dorsal view was also figured to show the structure of setal warts ( Fig. 182 View Figs ). The tibial spurs of O. vitrina   are extremely variable, with male specimens possessing tibial formulas of 0.2.2, 1.2.2, 1.3.2, 2.2.2, 2.3.2, or 2.3.3 and female specimens possessing tibial formulas of 0.2.2, 1.2.2, 2.2.2, 2.3.2, or 2.3.3.
