Type material. Female holotype from Guatemala, F.D. Godman [Sarg] leg., deposited in the Musée National d’Histoire Naturelle, Paris (NHM 1901.3.3.132), not examined.

Material examined. Nicaragua: Department of Matagalpa: Selva Negra, near Matagalpa, (12.9836°N, 85.9002°W), 1251m, 25–30 May 2012, K.B. Miller, M. Leister, R. Mallis leg., 1 male ( MSBA 37271), 1 female ( MSBA 37272).

Diagnosis. Same as genus diagnosis.

Description. Male: Total length 6.4. Carapace length 3.0; width 2.7; yellow, pear-shaped, length> width, narrowed at the cephalic region, highest posteriorly at thoracic groove, anteriorly truncate, with dark radiating pattern on ventral surface, eight circular eyes in two rows, PER strongly recurved, AER recurved, lateral eyes one and a half diameter of median eyes, thoracic groove longitudinal ( Fig. 1 A).

Chelicerae yellow, length> width; with two widely spaced retromarginal cheliceral teeth subequal in size; with three promarginal cheliceral teeth, distal tooth widely spaced from proximal two teeth, proximal tooth the smallest.

Sternum yellow, circular. Labium yellow, rectangular, width> length, rounded distally. Endites yellow, rectangular, length> width.

Trochanters notched; legs yellow, patterned with dark spots and annulations; all legs heavily spined, tibia I with four pairs of long thin ventral spines, tibia II with five pairs of ventral spines, proximal four pairs long and thin, distal pair short. Metatarsi I and II with two pairs of long thin ventral spines. All spines placed in raised sockets. All tarsi with small claw tufts composed of dense setae arising from discrete oval pads, pads not fused to cuticle of the lateral tarsus, claw tufts do not conceal tarsal claws, all tarsi terminate in two tarsal claws bearing a single row of prominent denticles, weak scopula on ventral surface of all tarsi. No tibial crack observed.

Leg formula: IV, I, II, III.

Leg measurements: Leg I, 13.3 (1.0, 0.4, 3.1, 1.2, 3.2, 3.2, 1.2); Leg II, 12.0 (0.9, 0.4, 2.9, 1.2, 2.7, 2.9, 1.0); Leg III, 10.8 (0.9, 0.4, 2.6, 1.0, 2.5, 2.6, 0.8); Leg IV, 14.0 (1.0, 0.5, 3.4, 1.1, 3.1, 3.7, 1.2).

Opisthosoma length 3.2; width 1.9; oval, longer than wide, dorsum light yellow, laterally darkened, patterned with dark spots on distal half ( Fig. 1 A).

Ventrally with opisthosoma light yellow-brown, maculate.

Pedipalpus trochanter, femur, and patella light yellow; tibia orange-brown, large RTA placed on base of tibia, elongate, narrowed distally, with proximally placed spur on ventral surface, anterior edge of proximal half serrate, with large, thick dorsal spine on distal region of RTA ( Fig. 1 B–F). Dense oval brush of thicker curved setae on dorsal surface of cymbium ( Fig. 1 B–D, F); pedipalpus bulb with sperm duct visible; median apophysis short, curving medially; embolus, curving laterally into transparent conductor, blunt tegular apophysis projected antero-ventrally from middle of tegulum, most easily seen in lateral view ( Fig. 1 B–D).

Female: Total length 9.8. Carapace length 3.8; width 3.3; color and form as in male, pattern more distinct. Opisthosoma length 5.8; width 3.7; patterned with thick white medial stripe and dark lateral stripes; pattern on venter and legs more distinct, but as in male. Tibiae I and II armed with five pairs of ventral spines, proximal four pairs long and thin, distal pair short. Metatarsi I and II with two pairs of long thin ventral spines. All spines placed in raised sockets. Scopula extending to ventral surface of metatarsi on legs I–III, restricted to tarsi on leg IV. Claw tufts and tarsal claws as in male. Leg formula as in male.

Leg measurements: Leg I, 11.6 (1.0, 0.5, 2.8, 1.3, 2.7, 2.4, 0.9); Leg II, 11.1 (1.0, 0.4, 2.7, 1.2, 2.6, 2.3, 0.9); Leg III, 10.4 (1.0, 0.4, 2.5, 1.1, 2.3, 2.3, 0.8); Leg IV, 12.8 (1.1, 0.5, 3.3, 1.3, 2.7, 3.4, 1.2).

Pedipalpus terminating with tarsal claw bearing a single row of prominent denticles.

Epigynum with medial septum and rounded lateral lobes. Vulva with curved ducts terminating in globular spermathecae ( Fig. 2 A–B).

Distribution. Hoedillus sexpunctatus is known from Guatemala and the Matagalpa department of Nicaragua. In a field trip to Panama in 2015 an immature specimen belonging to the genus Hoedillus was observed by the primary author near the La MICA Biological Station, Coclé province, 424m, 23, July 2015 (Permit No. SC/A-21-15), extending the range of this genus south to Panama.
