M205c stereomicroscope

Types are deposited in the Institute of Zoology, Chinese Academy of Sciences (IZCAS) in Beijing. All specimens collected were preserved and observed in a 95% ethanol solution. The specimens were measured and examined under a Leica M205C stereomicroscope, and further morphological details were observed using an Olympus BX41 compound microscope. The male palp was dissected from the left side of the spider for further examination. The carapace measurements include the clypeus (except for Relictocera sp. which has a distinct clypeus). The length and width ratios were measured according to the length of the cymbium (including the cymbial protrusion) to its width. The internal genitalia of the female and the male palp were dissected and immersed in lactic acid for digestion. An Olympus C7070 wide zoom digital camera (7.1 megapixels) mounted on an Olympus SZX12 stereomicroscope was used to take photos at different focal plans. The photos were assembled with the image stacking software Helicon Focus 6.7.1 to generate high quality photos before further editing with Adobe Photoshop CC 2014. Leg measurements are given as total length (femur, patella, tibia, metatarsus, and tarsus). Leg segments were measured from their retrolateral side. All measurements are given in millimetres (mm). Terminology follows Li et al. (2014) (link), Tong and Li (2007) , and Deeleman-Reinhold (1995) .

The specimens were measured and examined with a Leica M205 C stereomicroscope, and further morphological details were observed with an Olympus BX41 compound microscope. Male palps were detached from the left side of the animal for further examination (except for Leclerceraxiangbabang sp. nov. whose right palp was detached). Carapace length was measured excluding the clypeus. Internal genitalia of the female and palpal bulbs were dissected and immersed in lactic acid. An Olympus C7070 wide zoom digital camera (7.1 megapixels) mounted on an Olympus SZX12 stereomicroscope was used to take photos at different focal planes. The photos were then transferred to the image stacking software Helicon Focus 6.7.1 to generate photos with a greater depth of field before further processing with Adobe Photoshop CC 2014. Leg measurements are shown as total length: femur, patella, tibia, metatarsus, and tarsus. Leg segments were measured from their retrolateral side. All measurements are given in millimetres (mm). All terminology follows that of Li et al. (2014) (link).

Specimens were examined with a Leica M205c stereomicroscope and an Olympus BX51 compound microscope. Genitalia were drawn with the aid of a drawing tube. Male genitalia were placed in concentrated lactic acid in a cavity slide for at least several hours before they were examined. Habitus photographs were made with a KEYENCE VHX-2000 – Super Resolution Digital Microscope System. Label data are cited verbatim, with separate lines on the same label indicated by a slash “/”; different labels are separated by a vertical line“|”.
