3. Bengalia emdeniella ( Lehrer, 2005) View in CoL , comb. nov.

Figs. 44–53 View FIGURES 44–52 View FIGURE 53 , 175 View FIGURES 173–186 , 188 View FIGURES 187–198 , 200 View FIGURES 199–210 .

Holotype male, China (Fujian, Yenpingfu ) ( BMNH), by original designation. For details see Type material below.

The synonymy below (and, consequently, the distribution) is tentative as far as many of the Chinese provinces are concerned. In view of the fact that a new species from Yunnan (see B. weii below) is based on specimens which all carried a “ Bengalia varicolor ” determination label, it is to be expected that several other records of “ varicolor ” from China by Chinese authors may actually refer to specimens belonging to B. weii or even other, undescribed species, rather than to B. emdeniella .

Bengalia varicolor: Fan, 1965: 193 , figs. 753–755. Misidentification, not varicolor Fabricius. China (Guangdong, Hainan, Jiangxi, Sichuan, Yunnan, Zhejiang).

Note. The vertical sclerotised sheet in the aedeagus of varicolor as interpreted by Fan (1965: fig. 755; repeated in later Chinese publications), and by Lehrer (2005, as fanzideliana ) is very narrow (dorsoventrally) in lateral view, but has a slight emargination along the anterior edge as in the emdeniella holotype. The narrowness may be due to foreshortening due to perspective of an aedeagus perhaps being figured from a dried state, and I consider it as the same species as emdeniella (see next entries). In addition the vertical sclerotised sheet appears fused with the mid-dorsal wall of the aedeagus, just as is the case in emdeniella holotype.

52. Lateral finger of left side. Scale = 0.25mm ( Figure 47 View FIGURES 44–52 ). Abbreviations: l. f. = lateral finger; pst. scl. = parastomal sclerite.

Bengalia varicolor: Fan, 1992: 532 , figs. 1108a, 1108i, 1108m. Misidentification , not varicolor Fabricius. China (Guangdong, Hainan, Jiangxi, Sichuan, Yunnan, Zhejiang).

Note. Fan again included Taiwan citing Hennig (1941), but Hennig’s specimens identified as varicolor belong mostly to emarginata Malloch (and a few to varicolor Fabricius ).

Bengalia varicolor: Fan, 1997: 451 , figs. 139a, 139m, 139i. Misidentification , not varicolor Fabricius. China (Fujian, Guangdong, Hainan, Jiangxi, Sichuan, Xizang, Yunnan, Zhejiang).

Note. Fan again included Taiwan, but this time without citing Hennig (1941). However, the localities listed for Taiwan (Fan 1997: 452, lines 1–2), i.e., Anping, Hengchun [formerly Koshun], Sokutsu, Tainan (all in Chinese script) are those listed by Hennig (1941) under varicolor . [I consulted Chiu et al. (1984) for comparison of the Japanese and Chinese names for these localities].

Bengalia varicolor: Feng et al., 1998: 1381 , fig. 2825 Jv. Misidentification, not varicolor Fabricius. China (Fujian, Guangdong, Guangxi, Hainan, Jiangxi, Sichuan, Xizang, Yunnan, Zhejiang).

Note. Feng et al., included Taiwan, but again, most likely on the basis of Hennig (1941).

Afridigalia emdeniella Lehrer, 2005: 38 . Holotype male, by original designation, China (Fujian: Yenpingfu ) (BMNH). Examined.

Afridigalia fanzideliana Lehrer, 2005: 42 . Unavailable (no type designation). See Rognes (2006: 457) for details. [ China]

Bengalia varicolor: Verves, 2005: 240 View in CoL , in part. Misidentification, not varicolor Fabricius. View in CoL Catalogue entry for China.

Diagnosis. Male. Length: 15mm (from Lehrer 2005). Frons at vertex / head width ratio: 0.295 (n=1) (measured on photograph). Fronto-orbital plate without proclinate orbital setae. Anepimeron with about 20– 25 black setulae on upper part of posterior half, below lesser ampulla. Fore tibia in basal half with a row of small spine-like setae of about the same size ( Fig. 175 View FIGURES 173–186 ). Mid tibia with a fringe of somewhat prolonged thin posteroventral setae in distal part, longest setae about twice the tibial diameter.

Fringe on hind tibia rather dense and long, situated on distal two-thirds or more of anteroventral surface, prominent also on ventral and posteroventral surface, the posteroventral fringe setae twice the tibial diameter or more.

ST5 flap ( Fig. 50 View FIGURES 44–52 ) longer than broad, with a deep marginal excavation almost reaching halfway to its base, and with diverging lateral edges.

Cerci strongly curved in lateral view. Surstylus without vestiture on underside. Process of bacilliform sclerite with a long point.

Distiphallus short and high, almost triangular in profile view. Projecting dorsolateral wings absent; middorsal wall broad, fused with vertical sclerotised sheet ( Figs. 47, 51 View FIGURES 44–52 ). Antlers rather short and projecting upwards and forwards, grooved on anterior side. No basal tooth present. Upper lip ( Fig. 47 View FIGURES 44–52 , upper arrow) not projecting beyond base of antlers in dorsal view. [The mid-dorsal wall is ruptured along the midline in the only available genital preparation, rupture seen in Figs. 47, 51 View FIGURES 44–52 ]. Lateral finger large ( Figs. 45, 51, 52 View FIGURES 44–52 ), spinose distally. Vertical sclerotised sheet very conspicuous and its anterior edge smooth, slightly concave, as seen in lateral view. Internal hypophallic lobes strongly converging as seen in ventral view. External hypophallic lobes folded in anterior part, presenting a forwardly facing wall, which is well sclerotised laterally, and which backwards ( Fig. 47 View FIGURES 44–52 ) and also inwards ( Figs. 45, 51 View FIGURES 44–52 ). Each parastomal sclerite has a small dorsal projection basally ( Fig. 51 View FIGURES 44–52 ).

Female. Unknown.

Distribution. China (Fujian, Guangdong, Guangxi, Hainan, Jiangxi, Sichuan, Xizang, Yunnan, Zhejiang).

Material examined. Type material. Afridigalia emdeniella Lehrer, 2005 . Holotype male, in BMNH, labelled (1) “Pres. By / Com.Inst.Ent. / B.M.1954-110.” [printed]; (2) “Suenson” [printed]; (3) “COM. INST: ENT: / COLL. NO. 11715” [printed]; (4) “ China ” [printed]; (5) “SP.NOV.” [handwritten]; (6) “YENPINGFU / Fukian Prov. / E. Suenson / 16 MAY 1935 ” [printed large label]; (7) “ Bengalia / varicolor F. / van Emden det 1953” [handwritten, except “van Emden det 195” which is printed]; (8) “ Bengalia ♂ / emdeniella Lehrer n. sp. / HOLOTYPUS / Det. Dr. A. Z. LEHRER / 2004” [printed]; (9) “ HOLOTYPUS ” [red printed label]; (10) “ Bengalia ♂ / emdeniella Lehrer n. sp. / HOLOTYPUS / Det. Dr. A. Z. LEHRER / 2004” [printed]; (11) “Published as / Afridigalia emdeniella / Lehrer, 2005: 38 / K. Rognes 23.v.2008 ” [printed]. The specimen is in good condition, one fore leg glued to card on pin. Dissected by Lehrer. Genitalia transferred to glass microvial from original large opaque plastic vial by K. R. Lehrer (2005) renders the type locality as “Yenpingen” but that is an error (cf. Fig. 53 View FIGURE 53 ).
