Tuberaleyrodes bruneiensis sp. nov.

( Figs 75–87 )

Puparium. White; elongate oval ( Figs 75 , 79 ); broadest at first abdominal segment region and constricted at thoracic tracheal pore area; 1400 µm long, 1000 µm wide.

Margin. Crenulate ( Figs 76 , 82 ), faintly and irregularly, 9–10 crenulations in 0.1 mm. Anterior and posterior marginal setae, each 37 µm long.

Dorsum. Submargin not differentiated from the dorsal disc. Submarginal lines evident. Submargin with 8 pairs of small, capitate setae; of these, three pairs placed on cephalic region, one pair each laterad of pro-, meso- and metathorax, first abdominal segment and laterad of caudal furrow. Subdorsum with six pairs of tuberculate setae, one pair each on cephalus and mesothorax and four pairs on abdomen, basal elevation in each of these much longer than the apical seta, apex capitate. Of the four pairs on abdomen, one pair each laterad of abdominal segment III– IV, V and two pairs posterior to segment VIII. Submedian area with a few tubercles along the bases of tuberculate setae. Longitudinal moulting suture reaching subdorsal area and transverse moulting suture reaching submedian area. Median length of abdomen longer than cephalothorax, median length of abdomen from origin of first abdominal segment to base of segment VIII measured 474 µm long. Thoracic tracheal furrows absent. Caudal tracheal furrow prominent ( Figs 81, 83 ), smooth, 175 µm long, 37 µm wide near the posterior end of vasiform orifice. Pockets discontinuous.

Vasiform orifice. Subcordate ( Figs 78 , 83, 84 ), posteriorly narrow, deeply notched, longer than wide, inner posterior and lateral margin of the orifice with irregular striae, 82 µm long, 75 µm wide; operculum subcordate, posteriorly concave, 42 µm long, 48 µm wide. Lingula visible, not reaching outside of the posterior margin of the vasiform orifice, star-like appearance (possibly overturned).

Venter. A pair of ventral abdominal setae 25 µm long, 40 µm apart. Caudal and thoracic tracheal folds ( Fig. 87 ) indicated with stipples. Antennae originating from mesal to prothoracic legs, reaching pro- and mesothoracic legs space ( Fig. 75 ) 125 µm (including keel 3 µm) long. Paired rostral setae 2 µm long. Microsetae at middle of meso- and metathoracic legs, 7 µm long. A pair of microsetae near apical pads of metathorax, approximately, 2 µm long. Spiracles and adhesive sacs visible.

Chaetotaxy. Cephalic, first abdominal and caudal setae on tuberculate elevation of dorsal cuticle whereas eighth abdominal setae capitate; cephalic setae 130 µm (basal elevation 112 µm + apical setae 18 µm) long; first abdominal setae 85 µm (basal elevation 67 µm + apical setae 18 µm) long; caudal setae 88 µm (basal elevation 67 µm + apical setae 18 µm) long; eighth abdominal setae capitate, cephalolaterad of vasiform orifice, 25 µm long. Submarginal capitate setae up to 16 µm long. Subdorsal tuberculate setae ( Figs 77 , 85 ) 125–188 µm (basal elevation 105–163 µm + setae 20–25 µm) long.

Material examined. Holotype. Brunei: Temburong District, ridge NE of Kuala Belalong , approx. 300 m alt., one puparium on slide, 30.x.1992, J. H. Martin (6189) ( NHM).

Host plant. Unidentified plant.

Distribution. Borneo: Brunei.

Etymology. The species is named after the country of its collection locality, Brunei. Remarks. This species somewhat resembles T. actinodaphnis in its puparial elongate shape but differs from it in the shape of puparium being constricted at prothoracic region, in number and placement of dorsal setae, and in having longer than wide and posteriorly narrow vasiform orifice.
