Saussure (1878): 537 [685]; Bolívar (1889): 426; Casto de Elera (1895): 219; Kirby (1906): 91; Bruner (1915): 263; Chopard (1968): 360; Gorochov (1996): 60

Type material examined (images). Male holotype (DORSA-BG00002S01), Philippines, Luzon Island , Manila, coll. Meyen ( MfN) .

Material examined. 2 males (UPLG.19.45, 57): Philippines, Luzon Island, Laguna, Paete , Barangay Ilaya Norte, UP Land Grant , N14.40167, E121.54278, 303.5± 4.1 m, 1649 hours; N14.39870, E121.54249, 349.0± 5.3 m, 2030 hours, 6 September 2019, on foliage, coll. M. K. Tan, J. B. Baroga-Barbecho, C. C. Lucañas and S. A. Yap, pinned and genitalia dissected (all UPLBMNH and ZRC)

Distribution. This species was described from the Philippines and is currently known only in Luzon Island. The holotype collected from Manila is apparently missing ( Hollier et al., 2013). This species was also known from Nueva Cáceres (now part of Naga) ( Bruner, 1915). Our material represents the first record of this species in La-guna—albeit not surprising—between Manila in the north of Laguna and Naga in the south of Luzon Island.

Genitalia description ( Figs. 2 C–E). The genitalia of the male holotype is partly missing, with only the epiphallus (including the bridge, posterolateral epiphallic lobes, posteromedial epiphallic lobule) and ectoparameres present; while rami, rachis (= guiding rod), endoparameres are missing ( Gorochov, 1996; Cigliano et al., 2020). The males from Laguna have very similar epiphallic morphology, which are distinct from other congeners: epiphallus (ep) with posterior margin broadly concave posterolateral epiphallic lobes (p.ep) slender, flattened and bent at 90° internally at the apex with apex subacute; posteromedial epiphallic lobule (m.ep) stout with obtuse apices; ectoparameres strongly sclerotized and stoutly triangular, each with a basal dorsal lobe with subacute apex, taper apically into an acute apex that slightly surpassing posterolateral epiphallic lobes. Here we describe the missing parts of the genitalia: endoparamere (en) forked posteriorly, anterior end straight but not surpassing rami; rami (r) slender, gently curved, anterior end acute; rachis (ra) straight, relatively narrow, anterior end somewhat arrowed-shaped, posterior end truncated and slightly surpassing posteromedial lobule of epiphallus.
