5. Bengalia spinifemorata Villeneuve, 1913

Figs. 44–51 .

Bengalia spinifemorata Villeneuve, 1913: 153 . Lectotype male (MRAC, examined), by designation of Lehrer (2005: 170–172). Type locality: Democratic Republic of Congo, Katanga, Sankishia [as “Sankisia”] [9°21'S, 25°54'E]. Bengalia spinifemorata: Rognes, 2006: 460 .

Diagnosis. Male. Length: 11 mm. Frons at vertex / head width ratio: 0.300 (n=1). ST5 flap deeply sunk into the hind part of the ST5 proper so that the hind margin of the flap at each side of the excavation is flush with the hind margin of the ST5 proper. Surstyli with parallel upper and lower edges, weakly concave on inside. Bacilliform sclerite process forming a very low protuberance. Semicircular sclerotisation narrow at apex. Tip of beak at level with apical end of semicircular sclerotisation and with junction of veil and veil process. Right and left part of veil vertical, without rib on anterior surface, partly sclerotised in lower half, and shorter and less transparent than in B. racovitzai and B. smarti (this may be due to a layer of greyish glycerol jelly still adhering to its anterior surface). Upper margin smooth and without serrations. Lower part of veil process flattened and expanded and denticulate along margin and on its flattened surface. Posterior part of hypophallic lobe half as wide as the anterior part as seen in ventral view. Dentate process distally widening somewhat in profile view.

Female. Unknown.

Discussion. Known only from the lectotype. Lehrer (2005: 170–172) designated as lectotype one of the specimens originally mentioned by Villeneuve (1913). Although the designation did not satisfy the original wording of Article 74.7.3 of the Code (ICZN 1999a) (since it did not “contain an express statement of the taxonomic purpose of the designation”), it satisfies the amended wording of the Article (ICZN 1999b) (since it does “contain an express statement of deliberate designation (merely citing a specimen as ‘lectotype’ is insufficient)”). Lehrer gives an express statement of deliberate designation.

It appears that the true B. spinifemorata may not have been seen by Zumpt (1956).

Distribution. Democratic Republic of Congo (Katanga).

Material examined. Type material. Lectotype male, designated by Lehrer (2005), in MRAC with labels as follows: (1) Sankisia / 4-IX-11 [handwritten]; (2) COLL. MUS. CONGO / Lualaba: Sankishia / 4 – IX – 1911 / (J. Becquaert) [handwritten except first line]; (3) R. DET. / 5575 / B. [printed except last line which is handwritten]; (4) PARATYPUS [printed on yellow label]; (5) Bengalia / spinifemorata / type Villen. [handwritten in Villeneuve’s hand]; (6) LECTOTYPUS [printed on white label that is glued to a bigger red label]; (7) Maraviola 3 / spinifemorata / ( Villeneuve, 1913) / LECTOTYPUS / Det.Dr.A.Z. LEHRER / 2004 [printed] ( Fig. 51 ). Lehrer (2005: 171) miscited “Sankisia …” as “Sankedia …” on one of the labels ( Fig. 51 , leftmost label), although the proper spelling was published by Villeneuve (1913). Dissected by Lehrer.
