( Figs 101–113 View FIGURES 101–104 View FIGURES 105–113 )

Puparium. Elongate oval ( Figs 101 View FIGURES 101–104 , 105 View FIGURES 105–113 ), white, broadest at transverse moulting suture to first abdominal segment region; 1250–1650 µm long, 950–1225 µm wide.

Margin. Smoothly and regularly crenulate, 9–15 crenulations in 0.1 mm. Margin not modified into pore in the tracheal pore opening area ( Fig. 102 View FIGURES 101–104 ), and can be recognised by shallow irregular crenulations ( Fig. 107 View FIGURES 105–113 ), but clearly modified into C-shaped invagination to form a visible caudal pore ( Fig. 113 View FIGURES 105–113 ).

Dorsum. Submargin with 14 pairs of tuberculate setae ( Figs 101 View FIGURES 101–104 , 105 View FIGURES 105–113 ), 7 pairs each on cephalothorax and abdomen, apical setae longer than basal elevation, setae fine, apically pointed, 132–158 µm (basal elevation 50–55 µm + apical setae 75–108 µm) long. All the submarginal setae reaching beyond margin of the puparium. Minute tubercles present in a row on median area of pro-, meso- and metathorax and on abdominal segments I–VIII ( Figs 106, 110 View FIGURES 105–113 ). A row of tubercles present on submedian area of abdominal segment I–VIII, near termination of abdominal segment sutures. Longitudinal moulting suture reaching margin and transverse moulting suture reaching outer subdorsal area. Median length of cephalothorax measured shorter (600–703 µm long) than abdomen (650– 945 µm long). Cephalothoracic and abdominal segment sutures reaching submedian area. The longest median length was of abdominal segment I and shortest of segment VIII; abdominal segment II and III subequal, segment IV longer than III; the order of median length of abdominal segment was noticed as: VIII<VII<VI<V<II=III<IV<I. The median length of abdominal segment VII is shorter (8–20 µm) than VI. The median length of abdominal segment I–VIII measured as: 80–100, 65–82, 65–82, 62–85, 65–80, 65–70, 45–63, 22–55 µm long, respectively. The vasiform orifice located anterior of pupal caudal end by more than three times of its own length. The distance between posterior end of vasiform orifice and caudal margin of puparium measured 152–220 µm long, 40–58 µm wide near caudal end of the orifice. Caudal furrow smooth ( Fig. 108 View FIGURES 105–113 ). Pockets discontinuous.

Vasiform orifice. Subrectangular to subcircular ( Figs 103 View FIGURES 101–104 , 112 View FIGURES 105–113 ); as long as wide or little wider than long, slightly notched at posterior end, 50–65 µm long; 52–68 µm wide; operculum subcordate, slightly constricted subapically, completely covering the orifice, 32–50 µm long, 30–45 µm wide. Lingula visible through uplifted operculum, normally hidden beneath operculum, globular, with a pair of setae subapically.

Venter. Antennae arising from mesal to base of prothoracic legs ( Figs 104 View FIGURES 101–104 , 111 View FIGURES 105–113 ), reaching middle of prothoracic legs, 80–102 µm (including keel 5–15 µm) long. A pair of ventral abdominal setae, cephalolaterad of vasiform orifice but within the boundaries of the dorsal eighth abdominal setae, 25–28 µm long, 47–55 µm apart. Microsetae present in middle of pro- and mesothoracic legs, 5–7 µm long and of metathoracic legs, 10–12 µm long.

Chaetotaxy. Anterior marginal setae 25–28 µm long. Posterior marginal setae 40–48 µm long. Cephalic, first abdominal and eighth abdominal setae capitate but caudal setae longer and pointed than remainders. Cephalic setae 10–23 µm long, first abdominal setae 12–23 µm long, eighth abdominal setae 5–20 µm long and caudal setae 53 µm (basal elevation 15–20 µm + apical setae 32–38 µm) long.

Material examined. Holotype and paratypes. Malaysia : Sarawak, Gunung Mulu National Park, a single puparium from first row of three puparia on slide under one cover slip, 27.vi.1978, V F Eastop 16, 291, J. H. Martin (275-81) ( NHM). The holotype slide bears three puparia, one placed in upper row and two below in second row, the right side puparium from second row is partly broken and the second puparium located on its side shrunken on abdominal segments. A single puparium from first row is complete and selected as the holotype .

Host plant. Unidentified plant.

Distribution. Malaysia: Sarawak.

Etymology. The species moniker ‘ aequalis’ is a Latin word for ‘equal’ reflecting placement of submarginal setae in a row on equal distance from margin.

Remarks. Fundamentally, this species resembles T. actinodaphnis in shape, but differs from it in having 14 pairs of submarginal setae arranged in a single row, a row of median and submedian tubercles on abdominal segments, and nearly subrectangular shape of vasiform orifice.
