description: <i>3. Trachelas devi</i> n. sp. (Figs. 15-21) <i>General:</i> Cephalothorax brown; legs yellow; abdomen black. Total body length 3.00 mm. Carapace length 1.10 mm. Carapace width 1.00 mm; abdominal length 1.90 mm; abdominal width 1.20 mm. Legs as in Table-I. <i>Cephalothorax</i>: Longer than wide, anteriorly narrowing, posteriorly overlapped by abdomen; cephalic region raised; cervical furrows weakly distinct; posteromedially with a fovea; radial furrows deeply distinct. Eyes pearly-white, based with black band, unequal in size, anterolaterals largest; anterior row of eyes strongly recurved and posterior row nearly straight; anteromedian eyes close while posteromedians distantly placed; laterals closely placed; ocular quad longer than wide. Chelicerae brown, strong, both inner and outer margins with 2 teeth (Figs. 17). Maxillae and labium brown, maxillae broad, longer than wide (Figs. 18); labium broad, as long as wide (Figs. 18); both maxillae and labium anteriorly scopulate. Sternum dark brown, broad, nearly heartshaped (Figs. 19). Legs long and slender, each of tibia and metatarsi I and 11 with 3 ventral spines; tarsi with 2 claws; leg formula 4132 and the measurements (in mm) as in Table-I <i>Abdomen:</i> Oval, dorsum submarginally with serially arranged black patches leaving the white longitudinal mid-dorsal area (Figs. 15) Epigyne and internal genitalia as in figs. 20 and 21. . <b>Table-I</b>: Measurments (in mm) of different parts of legs of <i>Trachelas devi</i> n. sp. <i>Male:</i> Unknown. <i>Holotype</i>: Female in spirit. Types are at present in the Depa~tment of Zoology, Government P. C. College, Bagerhat and will be deposited to the Museum of the Department of Zoology, University of Dhaka, Bangladesh, in due course of time. <i>Etymology: The species</i> is named after <i>the</i> famous Philosopher Dr. G. C. Dev of <i>Dhaka University</i>, Bangladesh. <i>Type-locality:</i> BANGLADESH: Dhaka, date 24.ii. I992, Coil. Biswas. <i>Diagnosis: The Indian Trachelas</i> species (Majumder &amp; Tikader, 1991) <i>do not</i> seem <i>to be</i> related <i>to the</i> present species <i>T. devi</i> n. sp. because <i>the</i> latter is <i>with abdomen broad at</i> anterior 1 1/3rd region, without <i>any</i> sigilla, <i>cephalic region not</i> constricted, contiguous anteromedian <i>and</i> lateral <i>eyes and</i> typical epigynum. <i>These</i> sufficiently justify <i>the erection</i> of <i>the</i> new species. Abdominal <i>shape</i> of <i>the</i> present species even <i>though</i> may <i>be</i> related <i>to the T. taiwanicus (Hayashi &amp; <i>Yoshida</i>, 1993)</i> <i>but stands</i> distinct because of <i>the</i> characters indicated above. <i>The</i> species <i>even</i> show <i>too many</i> structural differences, though it <i>has</i> a similarity in <i>the</i> general appearance <i>with that</i> of <i>T. japonicus</i> (Shinkai &amp; Takano, 1984). Therefore, <i>the species</i> is described as new <i>to</i> science.
