Diagnosis

Males of Dendroicius garigi Dhiya’ulhaq sp. nov. can be easily distinguished from those of the only other species Dendroicius hotaruae Lin & Li, 2020 by the finger-shaped tegular sclerite ( Fig. 6B, E View Fig vs sheet-like in D. hotaruae [ Lin & Li 2020: fig. 3b, e]), absence of dorsal embolic apophysis (vs present) and tibial apophyses merged into one large structure ( Fig. 6C, G View Fig vs multiple separate apophyses in D. hotaruae [ Lin & Li 2020: fig. 3e]).

Etymology

The specific epithet is taken from Jambi Malay, meaning ‘denticles’, referring to the denticles on the palpal tibia. Noun in apposition.

HABITUS AND COLORATION. Carapace dark-brown, covered in black setae; lateral margins with thin stripe of white setae starting medially up to posterior end; small patch of white setae below ALE. Chelicerae colored slightly lighter than carapace; dentition: two promarginal, one retromarginal. Opisthosoma oval, yellow, laterally with thin longitudinal stripe of white setae in between stripes of black setae. Legs dorsally covered in white setae. Anterior legs brown except pale tarsus. Leg I stouter than other legs. Posterior legs pale. Spinnerets pale, except brown tip of PLS.

PALP ( Fig. 6 View Fig ). Tibia length-to-width ratio 0.60. RTA wide with three apices: ventral apex rounded, median and dorsal apices triangular. Numerous small denticles present along dorsal edge of RTA and towards distal edge of tibia. Cymbium rather broad. Tegular lobe wide and expanded; tegular bump rounded with wide base, right next to small membranous area. Sperm ducts inverted J-shaped retrolaterally; slightly curved prolaterally. Tegular sclerite pale, slightly shorter than embolus. Embolus needle-shaped, slightly more than third of length of bulb, forming 60 degree angle towards bulb.

Female
