Crockeria kinabalu Benjamin, 2016: 195, figs 92, 93, 96–99.

Material examined.

Indonesia – Sumatra, Jambi Province • 1 ♂; Batang Hari, Bajubang, Bungku ; 01°55'41.6"S, 103°15'34.2"E; elev. 48 m; 9 May 2013; J. Drescher leg.; canopy fogging in jungle rubber plantation; GOET 2013_HJ 1.1_AraThom 033 N_001 (to be transferred to MZB) .

Diagnosis.

Males of Crockeria kinabalu Benjamin, 2016 are distinguishable from Crockeria neofelis Dhiya’ulhaq & Benjamin , sp. nov., by the elongated MA (Figs 9 D – F , 10 ; Benjamin 2016: fig. 96) (vs wide, pincer-shaped; Figs 11 E, F , 13 A, B ); tapering, filiform conductor (vs membranous, triangular with rounded-tip); filiform embolus (vs short, needle-shaped); hook-shaped RTA (Figs 9 D , 10 A ; Benjamin 2016: fig. 97) (vs RTA with a flat, spatulate tip; Figs 11 E , 13 A ). Females are distinguishable from Crockeria laevis ( Thorell, 1890) by the smaller CO ( Benjamin 2016: figs 95, 98, 99) and from C. neofelis by the larger, inward-facing CO (vs smaller, outward facing; Figs 12 C, D , 13 D ) and lack of epigynal windows. Furthermore, the abdomen is uniformly coloured (Fig. 9 A ) (vs patterned in the other two species (Figs 11 A , 12 A ; Benjamin 2016: fig. 94).

Figure 29. Distribution of examined Thomisidae species from the Epidius clade (sensu Benjamin, 2011) prior to the present study, as well as the sampling location of the current study in Jambi Province, Sumatra, Indonesia (green flag). The new genus and the five new species described in the present study are all from the same study location, i. e., a replicated plot design across lowland rainforest, ‘ jungle rubber’ (rubber agroforestry), and smallholder monoculture plantations of rubber and oil palm in Jambi’s lowlands (Drescher et al. 2016).
