Diagnosis. A species often with somewhat darkened scutum, pleura, and abdomen; latter sometimes with rather broad black marginal bands. Male. Length: 7–13mm (mean 10.1mm, n=7). Frons at vertex / head width ratio: 0.317 –0.358 (mean 0.336, n=13). Lunula bare. Frontal vitta usually bright yellow anteriorly, often contrasting strongly with darker hind part. Fronto-orbital plate usually without proclinate orbital setae, but a paralectotype male (ZMAN…0118.11) has two proclinate orbital setae on each side, about 2/3 as long as the reclinate prevertical seta. The other males sometimes have a few of the orbital hairs outside of the frontal setae somewhat enlarged but never as strong. Legs yellow, femora often darkened, especially on anterior side. Anepimeron with a bundle of about 25 black setulae among the yellow ground vestiture, all well separated from the katepisternum.

Fore tibia ( Fig. 178 View FIGURES 173–186 ) with 7–8 small ventral spine-like setae in proximal half, 2–3 larger than the others; prolonged ground setulae forming a slight fringe distally on ventral side, the setae longer than tibial diameter. Mid tibia with pv fringe distally, fringe setulae much longer than tibial diameter ( Fig. 191 View FIGURES 187–198 ). Hind tibia with fringe of long densely set av, v and (to a lesser extent) pv setae at distal half or two-thirds ( Fig. 203 View FIGURES 199–210 ).

ST5 flap ( Fig. 90 View FIGURES 83–92 ) with a usually straight or very slightly convex posterior border as seen from above,

Cerci narrow in dorsal view, curved in lateral view. Surstylus with a dense cover of pale setulae on ventral side ( Fig. 83 View FIGURES 83–92 ). Triangular projection of bacilliform sclerite pointed.

Area around lateral and ventral fingers, enlarged view. 92. Distiphallus from in front. Scale = 0.25mm ( Figures 84, 86, 87 View FIGURES 83–92 ). Abbreviations: l. f. = lateral finger; v. f. = ventral finger.

Distiphallus with prominent dorsolateral wings and broad, backwardly curving antlers with 2–3 tines at tip. Basal tooth strong. Upper lip projecting beyond base of antlers, distal edge convex in dorsal view, underside strongly concave as seen from in front ( Figs. 87 View FIGURES 83–92 , 96 View FIGURES 93–97 ). Lateral finger very conspicuous: long, thick, slightly curved, denticulate on all sides and projecting far beyond lateral edges of the hypophallic lobes ( Figs. 84, 86, 91, 92 View FIGURES 83–92 ). Ventral finger a narrow process in lateral view, projecting well below midventral wall, its anterior edge smooth, without denticles ( Figs. 87, 91, 92 View FIGURES 83–92 ). Inner and outer hypophallic lobes parallel, not converging with their counterparts. Outer hypophallic lobe with a conspicuous shelf ( Figs. 86, 87, 91 View FIGURES 83–92 ). Anterior end of midventral wall level with distal end of dorsolateral wings (thus much farther forward than in varicolor .

Female. Length: 7–11mm (mean 9.4mm, n=4). Frons at vertex / head width ratio: 0.333 –0.350 (mean 0.342, n=6). ST2 as long as wide with 2 well separated strong (though short) erect marginals, sometimes with 2 smaller, one outside each (4 in all). ST3 very short with 2 strong erect marginals as distant as the strong ones on ST2, and sometimes with 1–2 smaller on their inside. ST4 twice as long as ST3 with 6 strong mostly erect marginals in groups of three. The middle in each group stronger than the others, and erect, but sometimes the smaller setae are not developed. ST5 about as long as ST2, broadly triangular, hind end narrower than front end, broadly rounded, with two strong marginals.

Distribution. Indonesia (Java, also Sumatra [female specimen below]).

Material examined. Type material. Bengalia latro de Meijere, 1910 . This species was described on the basis of an unknown number of male and female specimens captured in “Semarang, Januar, November; Gunung Ungaran, October, Jacobson leg.; Semarang, Dezember, Drescher leg.”. All the localities are in Java, Indonesia. The syntypes present in RMNH and ZMAN, their labels, and their depository have been reported by de Jong (2000: 111). In addition there are two overlooked male syntypes present in USNM. All material has been examined and is detailed below. To fix the identity of the name Bengalia latro de Meijere, I have selected and labelled a lectotype. I have labelled all the remaining type material with red paralectotype labels. All the original syntypes of B. latro are conspecific, except for one female in RMNH which lacks a pair of discal setae on T5. Its abdominal sternites are shaped quite differently and have a different vestiture compared to the other syntypic females. It is obviously another species than latro .

Lectotype male, here designated, in ZMAN, labelled (1) “E. JACOBSON / Samarang. Java / Nov. 1909 ” [printed]; (2) “13/57” [printed]; (3) “ Bengalia / latro / de Meijere, 1910 / ZMAN type DIPT.0118.12” [printed on red museum label]; (4) My red lectotype label ( latro de Meijere ) ( Fig. 95 View FIGURES 93–97 ). Dissected by K. R. Abdominal tergites glued to card on pin. Genitalia in glycerol in glass microvial on separate pin with similar lectotype label. Paralectotypes. RMNH: 1 male and 1 female labelled (1) “ Java I. ’06 / Semarang. / Jacobson.” [printed, except “I. ’06” which is handwritten]; (2) “ Bengalia / latro / det. de Meijere.” [handwritten in de Meijere’s hand, except third line which is printed] ( Fig. 97 View FIGURES 93–97 ). Male dissected by K. R. 1 female labelled (1) “Semarang / Jacobson” [handwritten]; (2) “ Bengalia / latro. / det. de Meijere. / Cotype” [handwritten, except third line which is printed]; (3) “ Bengalia sp. (f) / not latro de Meijere / T5 without discal setae / ST2-5 very different / from latro / K. Rognes det. 2009”. This female lacks a pair of discal setae on T5 and is definitely not latro . It is also much larger than the other syntypic females and the ST2–5 are completely different in shape and setosity. 1 male labelled (1) “ Java / Jacobson” [handwritten]; (2) “Mus. Leiden” [printed], (3) “ Bengalia / latro / det. de Meijere.” [handwritten in de Meijere’s hand, except third line which is printed]. USNM: 1 male labelled (1) “ Java I. ’06 / Semarang. / Jacobson.” [printed, except “I. ’06” which is handwritten]; (2) “ SYNTYPE / Bengalia / latro / De Meijere 1910 / N. E. Woodley ’94” [red label, handwritten except “N. E. Woodley” which is printed]; (3) “ Bengalia / latro / de Meij. / det. de Meijere” [handwritten, upright script, not de Meijere’s]; (4) “ B. latro is in synonymy with / varicolor in James (1977) / but this specimen is / not that species. NEW ’94” [white handwritten label in N. E. Woodley’s hand]; (5) “ USNM / 2046748” [printed on white label]. Flap of ST5 intact and visible. Genital capsule removed and glued to card below specimen, above labels [aedeagus broken, but cerci, surstyli, pre- and postgonites visible]. 1 male labelled (1) “E. Jacobson / Samarang. Java / Nov. 1909 ” [printed]; (2) “13/58” [printed]; (3) “ Bengalia / latro de Meij. ” [handwritten folded white label in de Meijere’s hand, handwriting compared with same writing on RMNH specimens]; (4) “ USNM / 2046748” [printed on white label]. I had an accident with this specimen, and the left mid leg was knocked off and the tarsus lost. The leg has been glued to a card below the specimen above the labels. This male, still undissected but with the ST5 flap visible, and the female from Sumatra 1925 (see below) were studied by Malloch (1927: 410–412), but the genitalia he figured, including the ST5 flap, were not from any of these specimens. See treatment of Bengalia varicolor Fabricius, 1805 , below. ZMAN: 1 female labelled (1) “Semarang / Drescher. /12.1905” [printed, except “12” and “05” which are handwritten]; (2) “ Bengalia / latro / de Meijere, 1910 / ZMAN type DIPT.0118.1” [printed on red museum label]. 3 males and 3 females labelled (1) “ Java I. ’06 / Semarang. / Jacobson” [printed, except “I. ’06” which is handwritten]; (2) “ Bengalia / latro / de Meijere, 1910 / ZMAN type DIPT.0118.2–4 [for the males] 5– 7 [for the females]” [printed on red museum label]. 4 males labelled (1) “E. Jacobson / Samarang. Java / Nov. 1909 ” [printed]; (2) “13/56”, “13/46”, “13/48”, “13/52”, respectively; the one with the “13/56” label also carries a small label reading “ ♂ ” [printed]; (3) “ Bengalia / latro / de Meijere, 1910 / ZMAN type DIPT.0118.8–11” [printed on red museum label]. One of these males (…0118.11) has two proclinate orbital setae on each side.

Afridigalia tenggeria Lehrer, 2006a . Holotype male, in BMNH, labelled (1) “ WEST JAVA: / Tengger Mts. / Nungkodjadjar. / 4000'. V.1938 / B.M.1962-651” [printed]; (2) “ Afridigalia ♂ / tenggeria n. sp / HOLOTYPUS / Det. Dr.A.Z.Lehrer / 2005” [printed pink label]; (3) “ Afridigalia ♂ / tenggeria n. sp / HOLOTYPUS / Det. Dr.A.Z.Lehrer / 2005” [printed pink even larger label]; (4) My determination label ( latro de Meijere ). The specimen was somewhat damaged in the mail at reception. On the left side the fore and mid legs lack the tarsus. On the right side the mid leg lacks the tibia and tarsus. The right hind leg with three tarsomeres intact was loose in the box together with four tarsal fragments. The abdomen had been dissected and has spots of glue. The ST5 flap and the genitalia were in glycerol in a large plastic vial. The distiphallus had the left antler broken at base. I have transferred the genitalia to a smaller glass microvial with glycerol and

Other material. USNM: 1 female labelled (1) “ Fort de Kock / (Sumatra) 920m / 1925 / leg. E. Jacobson. ” [printed]; (2) “ Bengalia / latro / de Meij. / det. E. Jacobson ” [handwritten, similar to writing on male from Java ’06 in USNM, above; possibly Jacobson’s?]; (3) My determination label ( latro de Meijere ). This female was studied by Malloch (1927: 410–412) .
