Eosembia Ross 2007
No full textGenus: Eosembia Ross, 2007 Diagnosis. Male Eosembia are generally distinguished from other genera in the family Oligotomidae as follows: the anterior branch of the media (MA) is unbranched in the forewing and hindwing, the basal segment of the left cercus is slender and never lobed and the tenth abdominal tergite is completely divided. Males often are strongly bicolorous, being basically blackish brown except typically possessing a bright orange prothorax and bases of the forelegs. Distal segments of the antennae are commonly abruptly white, and setae are usually longer than the bearing segment. Terminalia with process of the left hemitergite (10 LP) usually broad, aedeagus usually sclerotic and broadened caudally. Hind basitarsus lengthened, second papilla very small or absent. The female is large, robust, and richly pigmented. Distal antennal segments are usually abruptly white. The prothorax and certain leg segments in some species are bright orange, but entirely dark in others. Intersegmental areas of the thorax, coxae and trochanters are whitish. Hind basitarsus often has two ventral papillae. Type species. Eosembia nepalica Ross, 2007: 578, by original designation Distribution.

II. 2008. All specimens collected by P. Poolprasert. Distribution. This species is only known in western, northern and northeastern Thailand Etymology. The specific epithet refers to the region of first discovery: Siam, former name of the Kingdom of Thailand. Description. Alate male (n = 9, mean (range) ± SD): Head width × length 0.7 (0.6–0.8) ± 1.13 × 0.9 (0.8 –1.0) ± 0.45 mm, body length 6.2 (6.0– 6.4) ± 1.05 mm, width 0.7 (0.6–0.8) ± 0.53 mm, forewing length 3.8 (3.7–5.9) ± 0.41 mm, hindwing length 3.3 (3.2–3.4) ± 0.19 mm. Head capsule elongate-oval, dark. Eyes dark lavender. Submentum trapezoidal with shallow medial concave anterior magin. Mandible dark and slender. Antennae short, brownish throughout, 16 -segmented. Thorax brownish throughout. Wings light brown with AM not forked. All legs entirely brownish. Hind leg with only one basitarsal papilla. Abdomen light brown with terminalia paler. Terminalia with forward projection of MS extending one-third length of ninth tergite (9), apex rounded. 10 LP slender, straight-sided and parallel-sided then constricted medially and slightly narrowed caudally with apex dorsally furrowed. Inner lobe of LCB finger-like, tapered distally leftward. LPPT sclerotized, without outer hook. 10 LP broad basally then tapered terminally with small outer hook at apex. 10 RP long, broad, gradually narrowing caudally, with mostly membranous inner margin. LC 1 very broad basally then slightly constricted to distal tip. Apterous female (n = 5, mean (range) ± SD): Head width × length 0.7 (0.6–0.8) ± 0.27 × 1.0 (0.9–1.1) ± 0.35 mm, body length 6.4 (6.3–6.5) ± 0.17 mm, width 0.7 (0.6–0.8) ± 0.29 mm. Head capsule dark, longer than wide. Eyes smaller and less reniform than in male. Antennae brown throughout, 14 -segmented. Thorax brownish throughout. All legs same color as thorax. Hind leg with only one basitarsal papilla. Abdomen cylindrical, brown throughout. Tenth sternite symmetrically divided longitudinally into two lateral plates. Cerci entirely medium brown. Remarks. This new species is very difficult to see in nature because its gallery is small, concealed beneath pulverized bark particles and fecal pellets. Most of the nests were also found under foliose lichens (Fig. 2 C). Females tend to be solitary in their galleries with their young. FIGURE 4. Illustrations of Dachtylembia siamensis n. gen., n. sp.

Discussion. According to Ross (2007), diversity of Embioptera in southeastern Asia is high, particularly so in Thailand. Teratembiidae was also included in a dichotomous key to the families and subsequently, teratembiids were reported as an oriental group. However, no species of this family was listed for this geographic area; therefore, Dachtylembia gen. nov. is considered the first known teratembiid in Thailand. Morphological characteristics of the new genus place it in Teratembiidae; however, the cladistic analysis has demonstrated that some species in Teratembiidae (e.g., Teratembia geniculata Krauss, 1911) and Oligotomidae (Haploembia solieri (Rambur, 1842), Aposthonia glauerti (Tillyard, 1932), A. gurneyi (Froggatt, 1904) and Oligotoma saundersii (Westwood, 1837)) are closely related (Szumik, 1994). The phylogenetic relationship of these two families including this new species should be reconstructed for further study.Published as part of Poolprasert, Pisit, 2014, Dachtylembia, a new genus in the family Teratembiidae (Embioptera) from Thailand, pp. 456-462 in Zootaxa 3779 (4) on pages 458-462, DOI: 10.11646/zootaxa.3779.4.3, http://zenodo.org/record/23065
