Coptotermocola clavicornis sp. n.
This monotypic genus is distinguishable from all other Termitohospitini most distinctly by the strongly carinate mesocoxal process (Figs 27, 38), and additionally by the compact antennae (Fig. 29) and short maxillary palpi (Fig. 33).
Body form (Figs 24–27) limuloid. Pronotum strongly convex, dorsally obscuring most of head; abdomen posteriorly tapered.
Head capsule (Fig. 28) transverse, widest behind eyes. Antennal fossae deep, as large as eyes and dorsally obscured by vertex. Eyes large and produced anterolaterally. Antennae (Fig. 29) compact with 11 articles; antennomere I longer than II–X and partially hidden within antennal fossae; antennomere II dilated at apex to receive antennomere III; antennomeres III–X strongly transverse and more than twice as wide as long, length increasing distally; antennomere XI fusiform; pedicles of antenomeres IV–XI obscured by apex of preceding article. Labrum (Fig. 30) transverse and semicircular, anterior margin broadly concave; disc basomedially sparsely covered with pores; epipharynx (Fig. 30) glabrous. Mandibles (Figs 31–32) asymmetrical, dorsally covered with numerous pores around middle. Right mandible (Fig. 32) with a small subapical tooth; anterior one fifth strongly curved adorally. Left mandible (Fig. 31) without a subapical tooth. Maxillary (Fig. 33) lacinia elongate and strongly recurved adorally, adoral margin with 11 setae; apical two setae without basal cuticular processes (spinose scale of Ahn and Ashe 2004), third apical seta with a proximal basal cuticular process, central five setae with paired basal cuticular processes, basal three setae without basal cuticular processes; galea tapered apically, apex densely furnished with long trichae; palpus with 4 articles; article I triangular; article II trapezoidal and dilated toward apex; article III oviform, more than three times longer than wide and sparsely covered with long setae; article IV slightly narrowed toward apex with inconspicuous pseudosegment, pseudopores present apicomedially. Mentum (Fig. 34) trapezoidal, disc covered with long setae and several pores near middle and lateral areas; anterolateral corners slightly produced and with a pair of long macrosetae. Labial (Fig. 35) palpus with 3 articles, first article a fusion of I + II; article I + II with a mediobasal seta on ventral surface (probably homologous to seta c of Sawada ), twin and medial pores present; article III almost half as long as article I + II with 2 pores at apex; ligula triangular with medial subtriangular area sclerotized; prementum wider than long, with 2 pairs of both real and pseudopores, and a pair of setal pores present; apodemes broad and longer than disc, dilated posteriorly with apices recurved internally and almost touching.
Pronotum (Fig. 36) transverse, widest at posterolateral angles; anterior margin concave with anterolateral angles slightly produced anteriorly; posterior margin rounded and slightly produced medially; marginal cuticle thin and somewhat translucent (Fig. 26). Prosternum reduced in length. Elytra (Fig. 37) subquadrate, slightly wider than long. Wings fully developed. Mesoventrite (Fig. 38) slightly shorter than metaventrite; mesoventral process produced as an extremely large structure widest medially and tapered at ends, microsculpture composed of longitudinal wavy lines and pores (Fig. 39), structure ventrally partially obscuring basal podomeres; mesocoxal cavity marginal bead complete, narrowly separated. Legs (Figs 40–42) stout and laterally flattened; femora subrectangular; apical tarsomeres longest, tarsal formula 4-4-5. Fore leg (Fig. 40) with coxa approximately as long as femur; trochanter subtriangular; tibia thin. Mid leg (Fig. 41) with coxa globular; trochanter very thin; tibia thin. Hind leg (Fig. 42) subrectangular and almost as long as trochanter and femur combined; trochanter globular-triangular; femur slightly dilated apically; tibia thin.
Abdomen (Figs 24–27) tapered posteriorly. Segment I represented by only tergite I fused to the metanotum. Segment II represented by only by tergite II. Segments III–VII with 1 tergite, 1 sternite, and 2 pairs of paratergites. Tergite VIII (Fig. 43) with a blunt apicomedial point. Sternite VIII (Fig. 44) with posterior margin rounded. Tergite IX (Fig. 45) fully subdivided dorsally by tergite X. Tergite X (Fig. 45) fully divided medially to base, only connected each other and tergite IX on anterior margin.
Median lobe of aedeagus (Figs 46–47) with basal capsule bulbous. Paramere (Fig. 48) with a structure appearing homologous to Seevers’ (1978) medial phragma produced apically. Spermatheca (Fig. 49) apically slightly bulbous.
The generic name is derived from a combination of the generic name of the host termite, Coptotermes Wasmann, 1896 and the Latin noun cola meaning “dweller”. The gender is feminine.
