For details see Type material below.      Bengalia unicolor  Séguy, 1946: 85. Holotypemale, fixed by monotypy, Pakistan(Karachi) (MNHN). Examined.  Note. Séguy did not explicitly state that he based his species on one specimenonly, nor did he use the word “ Holotype” or “Type” or similar expression in the published text, but only one specimenis present in MNHNfitting the information that Séguy published about the material before him, and I take the specimen to be a holotypefixed by monotypy. The specimens bears a Séguy “TYPE” label ( Fig. 143). Séguy (1946: fig. 1a) illustrated the ST5 flap.     Bengalia unicolor: James, 1977: 530. Catalogue entry.     Bengalia unicolor: Kurahashi & Afzal, 2002: 221. Pakistan( Baluchistan, Khuzdar). Single female specimen, not seen by me.    Note. Kurahashi& Afzalcite the holotypemale in MNHNto be among “Type material examined”. But their citation of the museum depository is preceded by a question mark (“…? ( MNHN).”) which seems to indicate that they did not examine the specimen, but only suggested that it was possibly housed in that museum.      Bengalia unicolor: Verves, 2005: 240. Catalogue entry.   Diagnosis. Male. Length: 11.5mm. Frons at vertex / head width ratio: 0.321 (n=1). Lunula with a pair of setulae. Anepimeron with long thin yellow setulae only, no black setulae. Fore tibia with a number of ventral spine-like setae in basal half, at least two of these much stronger than the other spine-like setae and about as long as tibial diameter ( Fig. 183). A distinct fringe distally on mid tibia, setae about twice as long as tibial diameter ( Fig. 196). Hind tibia also with a strong fringe, occupying distal three fourths of the tibia ( Fig. 208). Basal segment of hind tarsus with an avrow of delicate setae a little longer than segment diameter. Mid femur with the pvctenidium of short stubby spine-like setae continuing mediad slightly beyond middle of femur; about 15–18 spine-like setae in all, 4–5 longer pvsetae basad. ST5 flap rectangular, slightly longer than broad ( Fig. 146), the distal corners are somewhat bent dorsally so they appear slightly too short in the figure. Cerci strongly curved in lateral view. Surstylus narrow, blunt distally, bare below. Process of the bacilliform sclerite strongly pointed.   FIGURES 139–148.  Bengalia unicolorSéguy, male (from holotype in MNHN). 139.

Upper lip projecting beyond base of antlers, distal edge almost straight in dorsal view. Two dark lines apparent in dorsal and ventral views of upper lip ( Figs. 140, 141) mark the insertion from below of two supporting vertical walls. These are seen in lateral view as triangular flanges, very weakly sclerotised, the anterior edge (almost invisible in Fig. 142) passing from tip of lip to a point lateral to the ejaculatory opening. Lateral finger thin, slightly curved and smooth, a few denticles at tip only ( Fig. 147). Internal hypophallic lobes converging. External hypophallic lobes folded distally and end in two spatula-like projections proceeding forwards and ventrally ( Figs. 140, 142). Strongly sclerotised flaps on each side of the ejaculatory opening ( Figs. 140, 142, 148).  Female. Unknown.   Distribution. Pakistan.   Material examined. Type material.  Bengalia unicolor Séguy, 1946.  Holotypemale, in MNHN, labelled (1) “MUSEUM PARIS / KURRACHEE [= Karachi] / (Août – Sept.) / MAINDRON 133-96” [yellow label with black print]; (2) “TYPE” [red label with black print]; (3) “ Bengalia/ unicolor / ♂TYPE. Seg. / E. Séguy vid. 46” [white label in Séguy’s black handwriting, except “E. Séguy vid.” which is printed; a printed black line present along the lower edge of label]. Dissected by K. R. The specimen is somewhat teneral as evident from the protruding ptilinium and the slightly wrinkled abdomen. The abdomen had large black spots on each side of the anterior half of T4, slightly intruding on T3, but they disappeared after boiling in KOH. T1+2 had a very faint and narrow band, and T3 and T4 a broader black marginal band, but no black bands remained in the dissected abdomen. T1–5 (as a unit), ST1–5 including ST5 flap (as a unit), and genitalia are kept in glycerol in a glass vial on the pin.
