Kuwasima "" . (CHM). Supplementary description of male genitalia (Figs 16C, D , 27A-L ). Median lobe more than 1/3 the length of abdomen; sub-bullet-shaped in dorsal view, moderately arcuate in profile; dorsal plate dehiscent in basal 3/5; ventral plate longer, apically pointed upward, dehiscent in basal 4/5. Tegmen 9/10 as long as median lobe; moderately arcuate in profile. Parameres 9/20 the length of tegmen; apical 1/3 bi-lobed; lobes fringed with short, stout apical setae. Apical process of endophallus as Figs 16C, D , 27D-F ; nearly 1/4 as long as median lobe, sub-monolithic; the middle thick in profile, with a prominent, horn-shaped, dorsal projection; sides each ventrally connected to a winding semi-toroidal appendage; base sub-triangular-spatulate in dorsal view, in profile thick, bent upward. 8th sternite cotyledonary; apex in "V" -form emarginated; blade extensively thinned in middle; apex and sides fringed with hairs of various lengths; peduncle a little longer than blade, thickened near blade. 8th tergite sub-squarish; much larger than the sternite; apex fringed with hairs of various lengths. 9th tergite connected to 9th sternite (spiculum gastrale) with a pair of elongated struts; latero-apical corners produced, with a few short, stout setae.

Ditto, lateral. Remark. This specimen from Basilan was examined for comparative purposes. Genitalia of this species is described above, as endophallus was not included in the previous description ( Yokoi et al. 2016 ). Figure 17. A-L. Ceresium elongatipenne sp. nov. Holotype male.

Luzon, Bohol, Mindanao (Philippines), Basilan , Philippines (New record) ; Bali; Maluku; Waigeou; West Ilian; Papua (Indonesia); Papua-Newguinea; Vanikoro (Solomon Islands). Figure 20. A-J.

Scale bars: 0.5 mm ( D-F ); 1 mm ( A-C, G-K ). Note. The holotype was recorded from "Insularum Manillaum". There was no further indication. The distribution in Basilan is thus treated as a new record within the Philippines. Figure 23. A-L. Ceresium lingafelteri Vives. Male from Mindanao (New record). Genitalia. A.

Essentially, the external characteristics of this specimen from Basilan correspond to those of the holotype from Luzon. Its setose 9th tergite is noteworthy. Specimens from other localities should be re-examined in this regard. Figure 26. A-F. Examnes kawakamii Yokoi, Makihara & Noerdjito. Male from Basilan, Philippines. (New record). Genitalia. A.
