Description.
Female (
Holotype
). Body surfaces dull-shagreened dark pitchy castaneous but elytron smoother and brighter with violaceous lustre; antenna largely dark with contrasting testaceous segments 1+2 and 10+11. Surfaces essentially glabrous except conspicuous adpressed setae on elytral preapex-apex. Legs largely testaceous, tibiae tinged with fuscous.
Head: frontal surfaces evenly contiguous, frons flattened merging with gently convex vertex; these surfaces appearing dull-shagreened (actually with fine diametric granulatons at
50 x
); frons additionally with sparse deep punctures mostly smaller than interspaces; vertex largely impunctate on disc but becoming punctate above, surface with deep median sulcus; eye prominent, maximum diameter about 0.6 x as broad as interocular space; gena about 0.4 x as deep as eye. Antenna attaining mid-elytron; pedicel ca 7/12 as long as segment 3; flagellar segments slender with last 5 distinctly heavier. Prothorax 0.72 x as long as broad; side convex with stronger curvature along anterior half; posterior angle produced; basal margin beaded; discal surface evenly convex with small elliptical deep punctures commonly smaller than interspaces. Elytron rather evenly tapered to preapex and thence to extended “beaked” extremity; disc with basal 3/5 confusedly punctate, thence becoming regular with swollen interstices; humerus weakly produced but with 2 sharp posthumeral costae extending into apical 1/3. Ventral surfaces: propleuron smooth-shagreened, impunctate; metasternum as preceding; abdominal ventrites obscurely punctate but otherwise shagreened; ventrites in lateral profile gradually ascending to thorax; ventrite 1 with intercoxal piece narrow to basal breadth (14:107); ventrite 1 not quite as long as 4 remaining ones; last ventrite briefly and convexly emarginate at extremity flanked with finely serrate lateral margins. Legs: metafemur ± slender, incrassate, evenly thickened to middle; metatibia slender, apex briefly and slightly expanded. Genitalia: spermatheca with receptacle elongate-narrow and gently curved. Measurements: Body length

; head breadth 144 cmm; interantennal space 44 cmm; interocular space 80 cmm; eye 48 cmm; gena 20 cmm; pronotal length 148 cmm; pronotal breadth 206 cmm; elytral length
4.3 mm
; abdominal ventrites: 58:15:13:13:20.
Male (Allotype). Paler than female with body surfaces largely orange-fulvous but elytra slightly darker subcastaneous, dorsal surfaces additionally with a slight brassy lustre; antenna yellow- to orange-testaceous with intermediate segments darker; legs yellow-testaceous. Body surfaces not shagreened as in female but head and prothorax possessing a fine diametric microsculpture, the elytra nearly smooth; pronotum additionally with distinct punctures; elytron with punctures confused on inner basal quadrant and becoming striate apically and laterally. Abdominal ventrite 5 with small median depression, sides dentate before briefly emarginate apex. Genitalia: aedeagal apex as in Fig.
3f.

Remarks.
This is one of the larger
Taophila
, ranging up to about
5.5 mm
; it exhibits pronounced sexual dimorphism: the female dark and shagreened, the male paler in color and much smoother in body form and sculpture. Differs from
T. mars
,
n. sp.
in lacking teeth at the side of the prothorax and the nearly glabrous dorsum. The species commemorates Fauvel’s MS name,
cancellata
, perpetuating the label name attached to a single fragmented specimen from the ISNB Fauvel collection. The name is derived from the Latin
cancellus
, meaning lattice or screen, referring to the shagreened fine sculpture of the body surfaces in the female.
