bicolor is similar to the female and this species differs from the other Hymenoepimecis species by the following characteristics: fore wing hyaline yellowish, with apex blackish, metasoma orange, with posterior margins of tergites II-V narrowly black, tergites VI+ black,
sternite I with a high, laterally compressed, nasute ventral protuberance, ovipositor 1.0-1.3 times as long as hind tibia.
Tergites and
sternites undivided; setae uniseriate and acuminate.
Subgenital plate (Figs 26-28) subelliptical with a transverse fold; apical sderite semi-circular with a U- or V-shaped incision, posterior part convex, lateral margins swollen, anterior part inflated with clear median keel; basal sclerite inflated with median keel and its lateral margins slightly converging towards the 7th abdominal
sternite.
13); genital fork (
sternite 5) with V-shaped gap at base, inner surfaces of arms densely spinose (Fig.
1C, D) elongated, apically narrowed, distinctly exceeding the end of ninth
sternite, almost reaching the end of dististyles in lateral view (Fig.
In preparation for electron microscopy, female specimens were removed from alcohol and air dried for about 20 minutes prior to dissection of the subgenital plate (
sternite 7) with fine needles (Roboz Surgical Instruments, Gaithersburg, MD) and dissecting scissors (Fine Science Tools, Inc., Foster City, CA).
Sternites. They are present as follows:
sternite II without setae or lyrifissures;
sternite X and IX with 2 long medial setae and 2 short lateral setae; sternal setae simple and longer than tergal setae;
sternites not divided; and sternal chaetotaxy is shown in Table 3.
villiger released the odoriferous secretion by exudation to the seventh abdominal
sternite, the most common method of delivery among tenebrionids [5].
In primitive termites, there are no differences in the caste developmental pathways between sexes, and it is easy to discriminate between sexes using abdominal
sternite morphology (Weesner, 1969; Jones and La Fage, 1980; Zimet and Stuart, 1982; Myles and Chang, 1984; Henderson and Rao, 1993).
simplex are larger extending to
sternite VI with the posterior margin rounded medially and angling equally to the medial and lateral margins and overlapping for 2/3 to 3/4 of their length while opercula of T.
