description: 7. Bengalia lyneborgi James, 1966   
Figs. 98–108, 179, 192, 204, 214, 215.  
Holotype male, Philippines (Palawan) (ZMUC), by original designation. For details see Type material below.  
 Bengalia latro: Malloch, 1927: 412, “… several specimens from Mt. Maquiling, Los Banos, Baguio, and Cuernos Mts., Philippine Islands (C. F. Baker) …” only. Misidentifications, not latro de Meijere.   
 Note. I am basing this synonymy on the examination of 3 male and 5 female specimens from Los Banos, Mt. Makiling, Cuernos Mts. (all Philippine Islands), all Baker leg. in USNM (for details, see below). Although only a female from Cuernos Mts. carries a latro determination label by Malloch, it is likely that this determination label refers to all the Philippine specimens collected by C. F. Baker and seen by Malloch. For more details, see entry for Malloch in the synonymy of Bengalia varicolor Fabricius, below.   
 Bengalia lyneborgi James, 1966: 467. Holotype male, by original designation, Philippines (Palawan, Brooke’s Point, Uring Uring, 22 August 1961) (ZMUC). Only photographs of ST5 flap examined.   
 Bengalia lyneborgi: James, 1977: 529. Catalogue entry.   
 Bengalia varicolor: Rueda, 1985: 347. Misidentification, not varicolor Fabricius. Philippines.   
Note. Not examined, but Rueda’s illustrations of the ST5 flap (fig. 17) and the aedeagus in dorsal view leave no doubt about the identity of his material.  
 Bengalia lyneborgi: Rognes, 1997: 64 (fig. 24). [Tip of ovipositor.]   
 Bengalia lyneborgi: Kurahashi & Magpayo, 2000: 47. Philippines (Culion Is., Luzon, Mindanao, Negros, Palawan).   
 Afridigalia jamesi Lehrer, 2005: 45. Holotype male, by original designation, Philippines (Palawan, Uring Uring, Brooke’s Point) (WSUP). Not examined, but discussed by Rognes (2006: 465–466).   
 Afridigalia lyneborgi: Lehrer, 2005: 52. Philippines.   
 Afridigalia nicolasia Lehrer, 2005: 56. Holotype male, by original designation, Philippines (Busuanga Is., 4km N San Nicolas) (BPBM). Not examined, but discussed by Rognes (2006: 465–466).   
 Bengalia lyneborgi: Verves, 2005: 239. Catalogue entry.   
 Diagnosis. Male. Length: 10–11mm (n=4). Frons at vertex / head width ratio: 0.308 –0.329 (mean 0.316, n=7). Lunula bare. Fronto-orbital plate without proclinate orbital setae. Anepimeron with a small tuft of 8–15 black setulae. Fore tibia with a bundle of strong spine-like setae on proximal half of ventral surface, the largest seta slightly longer than tibial diameter (Fig. 179). Mid tibia without elongated pv or other setulae distally, only short ground setulae present, much shorter than diameter of tibia (Fig. 192). Hind tibia with long av setae in a not very dense fringe occupying a little more than distal half, no long setae in fringe on v or pv side, only a few short erect setulae (Fig. 204).   
ST5 flap (Fig. 105) almost square with a hind border which varies from almost straight with a slight emargination only, to a type with a quite deep emargination, the bottom of which forms a right angle.  
Cerci (Figs. 102, 103) with a depression in middle as seen in profile. Surstylus without vestiture below. The dorsal projection of the bacilliform sclerite is rather long and blunt.  
 Distiphallus with a strongly sclerotised upper lip in the form of a narrow, elongate and slightly upturned process (Figs. 98–100). Mid-dorsal wall perforated by a long dorsal opening along most of its length (Fig. 98, d. o.). Dorsolateral wings projecting horizontally. Antlers hardly sclerotised, short, slightly upturned and grooved on dorsal side, with small irregular processes basally and distally at the front wall of the groove. Lateral finger long and strong, projecting from a prominent vertical sclerotised sheet (Figs. 99, 100, 107). No ventral finger found. External hypophallic lobe inconspicuous, slightly folded in middle and weakly denticulate. Internal hypophallic lobes strongly reduced, without denticles, originating as very low folds close together near base of distiphallus and diverging towards middle and then disappearing. From within the distiphallus two strong sclerotisations curve outwards and forwards, enclosing between them two balloon-like structures with a complex system of internal sclerotisations on each side at the distal end of the ventral part of the distiphallus (Figs. 99, 100).   
 Female. Length: 9–10mm (n=5). Frons at vertex / head width ratio: 0.308 –0.342 (mean 0.324, n=6). ST1– 5 and ovipositor as shown Figs. 214, 215. A pair of strong marginals on ST2–4. ST5 elongate oval.   
 Distribution. Philippines.   
 Material examined. Type material. Bengalia lyneborgi James, 1966. Holotype male, Philippines (Palawan, Brooke’s Point, Uring Uring, 22 August 1961) (ZMUC). Only photographs of ST5 flap examined. ST5 flap about as shown in Fig. 105.
