Type species
Cambonilla securicula Jocqué gen. et sp. nov.
Diagnosis
Species of Cambonilla gen. nov. are recognized by the tubular protrusion around the pedicel and dispersed PVS, with rows of tiny denticles in males, absence of PVS in females; both sexes have a marbled pattern of the abdominal venter, strongly recurved PER and granulate carapace teguments.
Etymology
The genus name is derived from the country of the type locality Cambodia, in combination with the ending of its sister genus Heliconilla. The gender is feminine.
Description
MEDIUM SIZE SPIDERS (7.5– 7.3 mm). With granulate teguments of carapace (Fig. 2A), sternum and basal leg segments. Carapace longer than wide (L/W <1.29–1.65) with sparse cover of split pale setae (Fig. 2B); widest at level of coxae II, narrowed to about 0.63 times maximum width in males (Figs 2A, 5A) and 0.66–0.80 times maximum width in females (Fig. 6A) (cephalic width measured on posterior tangent of PME); domed (Fig. 2C), without cervical grooves, profile highest at fovea.
COLOUR (Fig. 5 A–D). Carapace dark brown; chelicerae, legs, mouthparts and sternum medium to orange brown; abdomen dorsum dark with pattern of numerous white spots without apodemes, in males anteriorly overlaid by transparent reddish orange oval scutum; venter with sepia pattern on dark background; sclerotized in front of epigastric fold, in males extended into short tubular extension around pedicel.
EYES. In two strongly procurved rows: PLE at level of AME (Fig. 2D). All eyes pale and subequal. Clypeus straight, height 2.8 to 4.2 times diameter of ALE (Figs 2D, 5C).
CHILUM. Single, well developed and delimited, protruding in the middle. Chelicerae conical with many evenly dispersed setae; without teeth; fangs about three times longer than wide at base (Fig. 2E). Labium triangular. Endites roughly triangular, converging (Fig. 5B). Sternum shield-shaped, almost as wide as long, with rounded precoxal depressions (Fig. 4 A–B); anterior margin straight, lateral margins with inter- and intracoxal triangular extensions; posterior tip slightly indented in males, rounded or truncate in females.
LEGS. Slender. Formula 4123 or 4132. Tibial process well developed in all legs. Spination reduced on legs I and II, well developed on III and IV. Most spines short and slender. Bothria with three ridges (Fig. 1F). Superior tarsal claws with up to 15 teeth on leg I and II (Fig. 3A), with up to 8 teeth on legs III and IV (Fig. 3B). One dorsal hinged hair on tibiae I and II (Fig. 3C). Mt II-IV with preening brush of chisel-shaped setae (Fig. 3D).
FEMALE PALPAL TARSUS. With claw turned inward over ± 30°, provided with four or five small, basal, prolateral teeth; with several spines; without distal patch of chemosensitive setae.
ABDOMEN. Oval; tracheal spiracle fairly small, provided with small rectangular scutellum. Both sexes with six spinnerets. ALS large, conical, biarticulate. PLS and PMS provided with 1 and 4 cylindrical gland spigots respectively. Colulus represented by haired field. Venter with dispersed thick setae in posterior half (Figs 5B, D, 8B, D) and with short PVS provided with rows of tiny denticles (Fig. 3 E–F), in ill-defined row and/or group in males; both absent in females; hinged hairs sparse (Fig. 6 B–C).
MALE PALP. Tibia with strong RTA (Figs 4D, 5E). Cymbium with a few small distal spines; without distal claw; with patch of chemosensitive setae (Figs 4 C–D, 5E), short lateral fold opening ventrad, reaching middle of cymbium; tegulum with large central membranous area (Figs 5F, 7A); MA situated near retrolateral distal part of tegulum; C relatively small; embolus with massive well delimited base, originating on posterior part of tegulum, long, bifid (Fig. 4E).
EPIGYNE. With central plate wider than long (Figs 6D, 7C, 9D, 10C). Spermathecae poorly delimited smoothly fused to copulatory ducts (Fig. 6E).
