Cristipocregyes rondoni Breuning, 1965a: 33 ; Rondon & Breuning, 1970: 329, fig. 3, i, type locality: Laos, Borikhamxay Prov., Pakkading.

Type material examined. Holotype ( BPBM; Figs 31, 36 ): ♀, “ Parkading / 18-4 64 ”, “ LAOS: / Borikhane Prov. / Pakkading / 22. III. 1965 ”, “ J. A. Rondon / Collection / BISHOP MUS.”, “ Cristipocregyes / rondoni mihi / Breuning dét. Typ”.

Other materials examined. 1♂ ( BPBM, J. A. Rondon Coll.; Figs 16–17, 26 , 55–61 ), Phou Khao Khouay , Vientiane Prov., Laos, 31. VII, 1965 ; 1♀ ( BPBM, J. A. Rondon Coll.), Ban Van Heua , Vientiane Prov., Laos, 29. X, 1965.

Diagnosis. This species is easily distinguishable from the former species by having the following structures: body large; pronotum without black vittae; elytra with round maculae near apex.

Redescription. Male ( Figs 16–17, 26 ; n = 1): LB = 10.7 mm, WB = 4.5 mm.

Body reddish brown. Head, pronotum, elytra, and femora with sparse long suberect pearl white setae; inferior side of antenna and tibiae with dense same setae. Head clothed with dense pearl white and golden pubescence. Antenna with scape, pedicel, and each basal part of antennomeres 3–11 with pearl white pubescence, and the reminders with sparse brown pubescence. Pronotum clothed with pearl white and golden pubescence, of which golden one forms indistinct maculae around discal tubercles. Elytra clothed with white pubescence, scattered with several small tufts of black short setae throughout, provided with small macula of golden pubescence behind each basal ridge, wide longitudinal macula of same pubescence extending and obliquely dilating from behind humeri toward apex on each lateral side, a pair of large round maculae of white pubescence near apex. Dominant part of ventral surface and legs with light brown and pearl white pubescence.

Eye with LL/WL = 1.1, LL/LG = 1.4. Antenna 1.3 times as long as body; relative length of each segment as follows: 1.3: 0.3: 1.4: 1.4: 1.0: 0.9: 0.8: 0.8: 0.7: 0.7: 0.6. Pronotum with LP/WP = 0.9, LP/LB = 0.3, WP/ WEH = 0.7, provided with umbilicate, coarse and sparse punctures which are distinct in lateral and latero-dorsal side but reduced in disk; disk with three obtuse tubercles on middle, transversally depressed behind basal margin; lateral side with dull projection near apex. Elytra with LE/WEH = 1.6, LE/LB = 0.7, LE/LP = 2.4; disk with longitudinal obtuse ridge near each middle behind base, and several setigerous tubercles on base and basal ridge, entirely provided with small rough punctures which are distinct in basal part, though reduced apically and indistinct near rounded apex.

Male genitalia ( Figs 55–61 ; n = 1): tegmen slightly curved in lateral view. Paramere in dorsal view 1/4 of the length of tegmen, gently constricted in base, slightly curved in apical 2/3; ventral side with inwardly directed cylindroid projection behind base. Median lobe slightly curved in lateral view; median strut disjunct behind middle; ventral plate with apex roundly pointed. Endophallus about 2.5 times as long as median lobe; PB relatively long; APH rudimental, with ED on dorsal side of distal 1/3. MSp sparsely arranged in proximal 2/3 of MT+CT. LSp distributed in distal 1/3 of MT+CT in latero-dorsal side. SSp densely covered entire part of PB.

Female (n = 1): LB = 13.1 mm, WB = 5.6. Similar to male, but rotund. Antenna 1.1 times as long as body; relative length of each segment as follows: 1.4: 0.3: 1.5: 1.5: 1.0: 0.9: 0.8: 0.7: 0.7: 0.6: 0.5.

Distribution. Laos.

Taxonomic notes. This is the type species of the monotypic genus Cristipocregyes established by Breuning (1965a). According to the description ( Breuning 1965a) and the key to the genera of Mesosini ( Rondon & Breuning 1970), Cristipocregyes is different from Anipocregyes in the ratio between antennomere 3 and 4: antennomere 3 not longer than antennomere 4 in Cristipocregyes but longer than antennomere 4 in Anipocregyes ( Rondon & Breuning 1970) . However, the length of antennomere 3 is variable among the other members of Anipocregyes in the present study as shown in the description of each species. Furthermore, this species should be congeneric with Anipocregyes due to shared external and male genitalic features. Thus, Cristipocregyes rondoni is transferred to Anipocregyes and thereby Cristipocregyes is synonymized with Anipocregyes .
