6B76272AFF92FFBDFF3C5D6FFA0AFBA3.taxon	description	Imago. Unknown. Soldier (Figs. 1, 2, 6). Head capsule in dorsal view (Fig. 1 A) narrowing toward anterior, anterolateral corners with stubby knobs; very slight constriction in posterior third; posterior margin evenly convex. In lateral view (Fig. 1 B) head ellipsoid with steep frontal protuberance behind antennal sockets; frontal protuberance narrowly trapezoidal (Fig. 2 A) and conical in anterior (Fig. 2 B) and posterior view (Fig. 1 D). Frontal protuberance with tiny wart-like bump near middle of posterior margin (Fig. 2 A) and two curved setae on either side near summit (Fig. 2 B); summit without opening. Postmentum extending below genae, but not excessively so. Head capsule with pair of long straight setae on vertex behind protuberance and pair projecting laterally anterior to constriction. Four straight setae on submentum. Mandibles symmetrical, nearly straight with slight bend near bases; apical hooks about one-seventh of mandible lengths. Each mandible with triangular marginal teeth about two fifths length from hooks in lateral view when in resting position (Fig. 6). Thorax and anterior two thirds of abdomen filled with yellow defensive secretion. Antennae with 14 articles, or 15 if third subdivided, article formulae 2> 3 = 4 <5 or 2> 3 = 4 ≤ 5; Tibial spur formula: 2: 2: 2. Measurements. Head capsule length to postclypeus (mm) 1.59, 1.50; left mandible length to ventral condyle 1.54, 1.52; right mandible length to ventral condyle 1.53, 1.52; head width at antennal socket 1.06, 1.05; max. head width 1.30, 1.35; max. head capsule height (postmentum to protuberance) 1.25, 1.17; protuberance height from plane of vertex 0.25, 0.25; max. postmentum width 0.20, 0.19; max. postmentum height, 0.16, 0.16; max. pronotum width, 0.81, 0.78. Worker (Figs. 3 – 6). Monomorphic. Abdomen subspherical in dorsal view (Fig. 3 A, 6); integument transparent covered with hundreds of long setae. Postclypeus fully inflated in lateral view (Fig. 3 D). Pronotum angled ca. 100 º with anterior lobe larger than posterior; about 8 – 10 long setae along lobe margins. Tibial spur formula: 2: 2: 2. Fontanelle barely visible. Head capsule covered with sparse long setae. Antennae with 14 articles, or 15 if third subdivided. Digestive tube with spherical and large crop developed; mixed segment with narrow mesenteric tongue (Fig. 4 A – C); P 1 forming a semicircular tube from MS to P 2 insertion; P 3 large and globous in ventral view (Fig. 4 C) dorsal lobe exiting and partially surrounded by P 4; P 4 long and narrow. Enteric valve armature (Fig. 5 B) composed of six anterior and three posterior cushions. Posterior cushions with small spines becoming larger entering gut lumen. Anterior cushions project into gut lumen, finger-like; composed of fleshy outer lobes and inner ridges, ridges with each with about 100 thorny spines. Mandibles of soil-feeding type (Fig. 5 A). Left mandible with apical tooth twice the size of M 1 + 2, separated by acute angle; a sinuous margin between M 1 + 2 and M 3, M 3 much smaller than M 1 + 2; molar prominence without ridges, projecting. Right mandible with apical tooth more than twice the size of M 1, M 2 much smaller than M 1, molar plate without ridges and very concave. Measurements. Length of head with postclypeus (n = 10, min. - max., mean mm) 0.74 – 0.86, 0.80; max. head width 0.81 – 0.91, 0.87; length of hind tibia 0.86 – 0.96, 0.90.	en	Scheffrahn, Rudolf H.

6B76272AFF92FFBDFF3C5D6FFA0AFBA3.taxon	etymology	Etymology. “ Trapezia ” refers to the trapezoidal shape of the frontal protuberance in lateral view.	en	Scheffrahn, Rudolf H.

6B76272AFF92FFBDFF3C5D6FFA0AFBA3.taxon	diagnosis	Diagnosis. Soldiers of D. trapezia sp. nov. are unique among congeners in having a steep frontal protuberance that is narrowly trapezoidal in lateral view and its posterior margin is angled about 60 ° from plane of the vertex. Dentispicotermes trapezia sp. nov. is closest to D. globicephalus but the protuberance in the latter is triangular in lateral view and its posterior margin is angled about 30 ° from plane of the vertex. The D. trapezia sp. nov. worker gut and EVA is very similar to other species that I have examined: D. brevicarinatus and D. cupiporanga (Scheffrahn 2019).	en	Scheffrahn, Rudolf H.
